Download and install VirtualBox if you don’t already have it. Download the Oracle DB Developer VM (warning: it’s almost 8gb). Download the “Basic”, “SDK” and “SQL.Plus” packages of the Oracle Instant Client. Set up the Oracle DB Developer VM. First, in Finder, double click on the.ova file you downloaded. Follow VirtualBox’s. Hello everyone, in this video I am describing how to install SQLPLUS in easy steps. If you like this video please like and subscribe my channel to get the la. Instant Client 19.8 supports macOS High Sierra, Mojave, Catalina, and Big Sur. In Finder, double click on all desired Instant Client.dmg packages to mount them. All installations require the Basic or Basic Light package. Open a terminal window and change directory to one of the packages, for example. That could affect running SQL.Plus from a shell script, for example. There are workarounds for the 11g instant client. The installation notes at the bottom of the download page have changed since I last did this, and it now says to hard link the library files to the user's /lib directory to avoid that issue. Fortunately it looks like you don't. Sql Plus free download - FlashPlayer Plus, Magix Music Maker Plus, EZ-DJ Plus, and many more programs.

In this post we will learn how to How To Install MySQL on Mac OS X. The same procedure can be used for installing MySQL on Mac OS X. How to add MySQL to $PAT.

Modern, native client with intuitive GUI tools to create, access, query & edit multiple relational databases: MySQL, PostgreSQL, SQLite, Microsoft SQL Server, Amazon.
Installing SQLite on your Mac is pretty straightforward. Just follow these steps: Head over to SQlite.org and download the C source code file, named sqlite-autoconf-3130000.tar.gz or similar, from.
Find 'Macintosh OSX' and download both the Basic and SQL.Plus packages from the Instant Client downloads page. Move the contents of both into a single convenient folder (I used /Applications/Applicationfolders/instantclient). Add the location to your PATH variable, and also set DYLDLIBRARYPATH to point to it; for example.
Now some of the dylib files include versions in their filenames, but some programs such as SQL.Plus do not look for the versioned file, they look for the generic filename. So to resolve that problem, we need to also create links for them. Sudo ln -s libclntsh.dylib.11.1 libclntsh.dylib sudo ln.

Step 1: Download

You will need to download at least 3 files from oracle. In order to do so, you may need to register as an Oracle developer, or log in. The three files you need are the “basic”, “SDK” and “sqlplus” files for instantclient. They can all be found on the Oracle website.

instantclient-basic-macosx-<version>.zip
instantclient-sdk-macosx-<version>.zip
instantclient-sqlplus-macosx-<version>.zip

Download them to a temporary folder on your machine.

Step 2: Uncompress and Copy Files

Uncompress the files to the /op/oracle/ folder on your machine. You will have to first create the folder:

Install Sql Plus

Then uncompress the zip files in to that folder. You can do this from your temp directory with this command:

After you uncompress the files, you can create an alias for the instantclient folder. This will enable you to upgrade later, simply by changing where the link points.

Now some of the dylib files include versions in their filenames, but some programs such as SQL*Plus do not look for the versioned file, they look for the generic filename. So to resolve that problem, we need to also create links for them.

So up to this point, we now have all the files on our machine, and are ready to start configuring oracle client.

Step 3: Configure Oracle

You can configure oracle for all users of the system (and that is part of the reason we placed all the files in /opt/oracle instead of the users home folder.) But this configuration is per user, not system wide. Modify the users .bash_profile, and add the following lines:

You can set the NLS_LANG to be whatever is right for your situation, I choose AMERICAN_AMERICA.UTF8 since that is correct for me. You will also note I did not set the TNS_ADMIN folder to be /etc, the default location, instead I placed it in the users home directory. This is up to you, I find it easier to have each user manage their own TNS_NAMES. Finally it adds the executables to the path.

Once that is finished you can source the file, or open another terminal window, and then you will be able to run SQL*Plus.

You should be greeted by the version of the release that you just installed.

To configure your tns_names.ora file, if needed, you should create the directory etc in your home folder, and ad the file.

Using your favorite editor, edit the tnsnames.ora file. For more information on configuring the file, check this link.

After doing this a few times, I made a bash file that can do most of the work for you. You have to run this script from the folder after you have downloaded the oracle zip files.

Here I’ll show you how to get SQL Server up and running on your Mac in less than half an hour. And the best part is, you’ll have SQL Server running locally without needing any virtualization software.

Prior to SQL Server 2017, if you wanted to run SQL Server on your Mac, you first had to create a virtual machine (using VirtualBox, Parallels Desktop, VMware Fusion, or Bootcamp), then install Windows onto that VM, then finally SQL Server. This is still a valid option depending on your requirements (here’s how to install SQL Server on a Mac with VirtualBox if you’d like to try that method).

Starting with SQL Server 2017, you can now install SQL Server directly on to a Linux machine. And because macOS is Unix based (and Linux is Unix based), you can run SQL Server for Linux on your Mac. The way to do this is to run SQL Server on Docker.

So let’s go ahead and install Docker. Then we’ll download and install SQL Server.

Install Docker
Download the (free) Docker Community Edition for Mac (unless you’ve already got it installed on your system). This will enable you to run SQL Server from within a Docker container.
To download, visit the Docker CE for Mac download page and click Get Docker.
To install, double-click on the .dmg file and then drag the Docker.app icon to your Application folder.
What is Docker?
Docker is a platform that enables software to run in its own isolated environment. SQL Server (from 2017) can be run on Docker in its own isolated container. Once Docker is installed, you simply download — or “pull” — the SQL Server on Linux Docker Image to your Mac, then run it as a Docker container. This container is an isolated environment that contains everything SQL Server needs to run. Best smart tools v3 34.00 crack download.
Launch Docker
Launch Docker the same way you’d launch any other application (eg, via the Applications folder, the Launchpad, etc).
When you open Docker, you might be prompted for your password so that Docker can install its networking components and links to the Docker apps. Go ahead and provide your password, as Docker needs this to run.
Increase the Memory
By default, Docker will have 2GB of memory allocated to it. SQL Server needs at least 3.25GB. To be safe, increase it to 4GB if you can.
To do this: /download-mac-os-x-mavericks-full-version/.
1. Select Preferences from the little Docker icon in the top menu
2. Slide the memory slider up to at least 4GB
3. Click Apply & Restart
Download SQL Server
Now that Docker is installed and its memory has been increased, we can download and install SQL Server for Linux.
Open a Terminal window and run the following command.
This downloads the latest SQL Server 2019 for Linux Docker image to your computer.
You can also check for the latest container version on the Docker website if you wish.
Update: When I first wrote this article, I used the following image:
Which downloaded SQL Server 2017. Therefore, the examples below reflect that version.
Launch the Docker Image
Run the following command to launch an instance of the Docker image you just downloaded:
But of course, use your own name and password. Also, if you downloaded a different Docker image, replace microsoft/mssql-server-linux with the one you downloaded.
Here’s an explanation of the parameters:
-d
This optional parameter launches the Docker container in daemon mode. This means that it runs in the background and doesn’t need its own Terminal window open. You can omit this parameter to have the container run in its own Terminal window.
--name sql_server_demo
Another optional parameter. This parameter allows you to name the container. This can be handy when stopping and starting your container from the Terminal.
-e 'ACCEPT_EULA=Y'
The Y shows that you agree with the EULA (End User Licence Agreement). This is required in order to have SQL Server for Linux run on your Mac.
-e 'SA_PASSWORD=reallyStrongPwd123'
Required parameter that sets the sa database password.
-p 1433:1433
This maps the local port 1433 to port 1433 on the container. This is the default TCP port that SQL Server uses to listen for connections.
microsoft/mssql-server-linux
This tells Docker which image to use. If you downloaded a different one, use it instead.
Password Strength
If you get the following error at this step, try again, but with a stronger password.
I received this error when using reallyStrongPwd as the password (but of course, it’s not a really strong password!). I was able to overcome this by adding some numbers to the end. However, if it wasn’t just a demo I’d definitely make it stronger than a few dictionary words and numbers.
Check the Docker container (optional)
You can type the following command to check that the Docker container is running.
If it’s up and running, it should return something like this:
Install sql-cli (unless already installed)
Run the following command to install the sql-cli command line tool. This tool allows you to run queries and other commands against your SQL Server instance.
This assumes you have NodeJs installed. If you don’t, download it from Nodejs.org first. Installing NodeJs will automatically install npm which is what we use in this command to install sql-cli.
Permissions Error?
If you get an error, and part of it reads something like Please try running this command again as root/Administrator, try again, but this time prepend sudo to your command:
Connect to SQL Server
Now that sql-cli is installed, we can start working with SQL Server via the Terminal window on our Mac.
Connect to SQL Server using the mssql command, followed by the username and password parameters.
You should see something like this:
This means you’ve successfully connected to your instance of SQL Server.
Run a Quick Test
Run a quick test to check that SQL Server is up and running and you can query it.
For example, you can run the following command to see which version of SQL Server your running:
If it’s running, you should see something like this (but of course, this will depend on which version you’re running):
If you see a message like this, congratulations — SQL Server is now up and running on your Mac!

A SQL Server GUI for your Mac – Azure Data Studio

Azure Data Studio (formerly SQL Operations Studio) is a free GUI management tool that you can use to manage SQL Server on your Mac. You can use it to create and manage databases, write queries, backup and restore databases, and more.

Here are some articles/tutorials I’ve written for Azure Data Studio:

Another Free SQL Server GUI – DBeaver

Another SQL Server GUI tool that you can use on your Mac (and Windows/Linux/Solaris) is DBeaver.

DBeaver is a free, open source database management tool that can be used on most database management systems (such as MySQL, PostgreSQL, MariaDB, SQLite, Oracle, DB2, SQL Server, Sybase, Microsoft Access, Teradata, Firebird, Derby, and more).

How To Download Sql Plus On Mac Os

I wrote a little introduction to DBeaver, or you can go straight to the DBeaver download page and try it out with your new SQL Server installation.

Limitations of SQL Server for Linux/Mac

SQL Server 2017 for Linux does have some limitations (at least, in its initial release). The Linux release doesn’t include many of the extra services that are available in the Windows release, such as Analysis Services, Reporting Services, etc. Here’s a list of what’s available and what’s not on SQL Server 2017 for Linux.

Another limitation is that SQL Server Management Studio is not available on Mac or Linux. SSMS a full-blown GUI management for SQL Server, and it provides many more features than Azure Data Studio and DBeaver (at least at the time of writing). You can still use SSMS on a Windows machine to connect to SQL Server on a Linux or Mac machine, but you just can’t install it locally on the Linux or Mac machine.

How To Download Sql Plus On Mac Windows 10

If you need any of the features not supported in SQL Server for Linux, you’ll need SQL Server for Windows. However, you can still run SQL Server for Windows on your Mac by using virtualization software. Here’s how to install SQL Server for Windows on a Mac using VirtualBox.

Update, 2009:

Since I wrote this article in 2007 there have been new releases of Oracle (including 10g Express Edition for Linux),Parallels, VirtualBox, Mac OS and every flavour of Linux.Ubuntu has become a favourite desktop Linux, and is now supported by Oracle, including a convenient XE installation.Parallels Tools now provides file sharing for Linux, and Oracle provides pre-built VirtualBox demo VMs for download.Many of us who moaned about the lack of an Oracle version for Mac have found that we don't really need one after all.

I have not updated the document to reflect these changes.If you just want a quick and easy Oracle installation,have a look at Oracle Express Edition for Linux.You still have to increase the swap space as shown below, but otherwise the installer takes care of just about everything.

Introduction

Back in 2002, Oracle announced 9.2 Early Adopters' Edition for Mac OS 10.2. It was theoretically for OSX Server rather than the desktops and laptops we allwanted it for, you had to jump through a few hoops to get it working, it had no internal JVM, it didn't do Native Compilation, and SQL*Plus took up to tenseconds to connect. However, I had Oracle on my G3 iMac and that was pretty cool.

A couple of years later, out came 10g for Mac OS 10.3. This was a simpler install, everything worked, and we seemed to be getting somewhere.Unfortunately, there progress stopped. When Mac OS 10.4 came out, you could just about install 10g if youjumped through some more hoops - but soon there was a new range of Macs that ran on something called an 'Intel chip', and Oracle did not run on that.So from 2006 with the whole Apple range now running on Intel, there is no Oracle product for either the OS version or the hardware platform.

However, Parallels Desktop For Mac has been getting some great write-ups, as it makes use of the Mac'sshiny new Intel chip to run software compiled for Intel with almost native efficiency.A virtual database server even has some advantages, since you'll get a client-server setup that's similar to many commercial Oracle installations.It'll also be easy to experiment with configurations, and you can make a backup by simply copying the Parallels .hdd file.

Note about Howard Rogers/Dizwell links

Shortly after this article was written, Howard Rogers closed the Dizwell site.Unfortunately this article linked to some excellent animated installation guides that were there.These days (as of 2015), following a complete site overhaul, he is writing again and you can download his pre-built Centos/Oracle disk image fromwww.dizwell.com.

There are other easy-to-follow CentOS and Oracle installation guides about, for example Tim Hall's Linuxand Oracle installation guides on Oracle Base.

I hope the remainder of this article is still useful.

Overview

What we're going to do is:

Create a Parallels virtual machine.
Install CentOS, following Howard Rogers' CentOS installation guide for VMware (similar to Parallels).
Install Oracle, following Howard Rogers' Oracle installation guide for CentOS.
Install Oracle Instant Client For Mac OSX so we can have SQL*Plus in a Mac Terminal window, just like old times. (The Instant Client also includes JDBC and ODBC drivers etc.)
Optionally, we'll also set up iSQL*Plus, SQL Developer and anything else I can get working.

This will give us a virtual database server that will appear like another computer on the network. For most purposes we'll be able to connect to the database from the Mac,without having to log into CentOS at all.

Download the software

Parallels Desktop for Mac

Parallels Desktop for Maccosts $79.99 (£42) at the time of writing, although you can download a time-limited free trial.

CentOS

You also need a guest OS capable of running Oracle.Many choose Windows for its convenience and the ability to use tools such as PL/SQL Developer or(if you must) TOAD.However, Redhat Linux is an Oracle-supported platform (2006's Oracle Unbreakable Linux is essentially Redhat with an Oracle badge),and CentOS is a free Redhat clone.You can buy CentOS on DVD (it's very cheap since you are only paying for the distribution costs) or download a disk image in .iso format.It's further complicated by a choice of versions (I chose CentOS 4.4 for i386), mirrors (I chose the 'actual country' download mirror site, in my case UK),formats (single DVD rather than multiple CD) and download methods (I chose Bittorrent). (Update: CentOS 5 is the current release as of Summer 2007.)

You can download Bittorrent free from www.bittorrent.com. With Bittorrent, you download a small control file such as CentOS-4.4-i386-binDVD.torrent, and open it in the Bittorrent application, which drives the actual download. I started it up and left it running overnight. (I'm told Bittorrrent can be extremely fast, but in my case it wasn't. If you have problems there is a lot of help on the Net.)

Oracle 10g

At the time of writing, this is Oracle Database 10g Release 2 Enterprise/Standard Edition for Linux x86 32 bit.There is no convenient way provided to share files between the VM and the host, although we can set up an NFS share later,which allows you to access Mac files directly from Linux.

Create a new Virtual Machine

Parallels' supplied help explains how to get this started. Essentially you create a new virtual machine (VM) using the 'Install OS' button, and follow the onscreen instructions.

Choose 'Custom OS installation' (Windows users get a handy Express option, but no such luck for Linux).
For the OS Type, choose Linux and Red Hat Linux (RHL is the same as CentOS for our purposes).
I gave it 756 MB of RAM (my iMac has 2 GB), and 15 GB (15360 MB) of disk space, selecting Plain rather than Expanding (it said it would run faster). You could make it bigger, but huge files are slower to back-up, copy and so on. (However, if you install Application Express you will need at least 936 MB of memory, and a bit more disk space.)
For the hard disk image file location, I chose a spot on my Firewire drive (a subfolder per VM is a good idea).
For networking, choose 'Bridged Ethernet' (see 'Networking for Dummies' box, below).
'Default adaptor' will do (this lets it choose between Ethernet or Airport automatically), or just pick Ethernet.
Give the VM a name. This is the name within Parallels, not the CentOS hostname.
Select 'ISO file' for the installation media, and show it the CentOS .iso file you downloaded earlier. Hit 'Finish' and be prepared for a ten minute wait while it formats 15GB of disk space.

Install CentOS

Follow Howard Rogers' guide to installing CentOS 4.

Note however that this is written for VMware on Windows, and the networking set-up steps are subtly different in Parallels for Mac. (Those who are already familarwith this stuff will take it in their stride, but the rest of us may need to look at Networking for Dummies, below.)

Resist the urge to use the CentOS 'Up2Date' tool in the top right corner to get all the CentOS system tools up to date, at least until you have installed Oracle and made a backup(i.e. copied the .hdd file - or in Parallels 3.0, created a snapsot).For example some system libraries may be altered or renamed by an upgrade, and you'll have to start tweaking installer scripts to get them to work, without really knowing what effect the changes had.

Note that 'Parallels Tools' are currently only available for Windows, OS/2 and Solaris, and not for CentOS. This isn't a big deal, but just means we don't get aconvenient way to switch context or copy and paste between the Mac and the VM.(NoMachine NX Client is worth a look, although I haven't tried it myself. I'll update this document if I do.)

There is also no way provided to share files between the VM and the host, but you can set up an NFS share. To keep this installation guide simple, I have written a separateNFS setup guide. (If you are not familiar with the networking involved, you may want to read 'Networking for Dummies', below,before tackling NFS.) With NFS in place, you can download and unzip the Oracle software to the Mac, rathr than having to download it separately withinany VM you create.

It may also be an idea to add some extra swap space, depending on how much memory you gave the VM. For example to add 512MB, execute the following commandswith root privileges (either become the root user first using the command su -, or place sudo in front of each command and enter your own password when prompted):

dd if=/dev/zero of=/etc/extraswap bs=1M count=512
mkswap /etc/extraswap
swapon /etc/extraswap
Edit /etc/fstab to include the line:
/etc/extraswap swap swap defaults 0 0
After adding the new swap file and enabling it, make sure it is enabled by viewing the output of the command cat /proc/swaps or free -m (the '-m' option makes it display in megabytes).

Networking for Dummies

Parallels provides three Network Adapter options, which represent the different ways the VM can connect to the local network.The static IP address will depend on the network adaptor we select.(You can easily change it later, so feel free to experiment.)

Bridged Ethernet: the VM becomes a peer of the Mac. They will be in effect two machines sharing a common network gateway, which means their IP addresses must be in the same range. I'll be using this option.
Host-only Networking: the VM becomes a client of the Mac. It can only see (and be seen by) its host machine, and won't have Internet access. Its IP address should be in the same range as 'Parallels Host-Guest' (see screenshot below).
Shared Networking (Network Address Translation): the VM and the Mac will appear as a single machine. Parallels recommend this for a quick and easy general purpose set-up, but it is not ideal for a database server.

At the Network Configuration screen in the CentOS installer, the default setting is to use DHCP. You do not want to use this.DHCP (Dynamic Host Configuration Protocol) is great at automating network configuration,but because it dynamically hands out temporary IP addresses, any Oracle utility you configure by specifying the IP address will break sooner or later at the whim of DHCP.

Sql Plus Download Oracle

In VMware on Windows (as in Howard's guide) you would check the VMware settings to find the VM's name on the network, such as'VMnet1', type ipconfig in a cmd window to see VMnet1's IP address, and use that information to pick a new static IP address back in the CentOSinstaller. However, this is where VMware and Windows differ from Mac OSX and Parallels. OSX does have an 'ipconfig' command, but it's a rather different beast and requiresa bunch of additional parameters depending on what type of information you are interested in.

The related command ifconfig gives me output like this (I've changed a few random values in case any hackers are reading this):

The label on the left identifies the network device, in this case en0, the Mac's Ethernet connection(I used the -u en0 option so it only shows en0, and not Airport or my Firewire drive)and it's telling me that its address is 10.0.1.2 and the subnet mask is 255.255.255.0 (shown in hexadecimal as ff ff ff 00).

Alternatively, open System Preferences, Network, and look at the 'Network Status' page: you may see an entry something like this (depending on your network connection of course),which tells me that my Mac's internal IP address is10.0.1.2:1This is behind my firewall - when I connect to a public Internet website I will appear to have a different address, set by my ISP.

If you are on wi-fi it's even easier - Option-click the Wi-Fi symbol in the menu bar.

The two Parallels entries below it apply to Host-Only Networking and Shared Networking. Since I'm not using either of these right now they are not relevant.The new static address I'm going to use for CentOS will be of the form 10.0.1.xxx; that is, matching the Mac's address but with a different number in the finalslot.2 If we were using Host-only Networking as in Howard's example, we would read the 'Parallels Host-Guest' address from the 'System Preferences, Network' screen, and choose an address in the same range, for example 10.37.129.10.

The two other pieces of information you will need are the addresses of the DNS server and the default gateway(in my case the router, although in some setups it could also be a proxy server). DNS looks up names such as 'williamrobertson.net' and translates them into IP addresses.On home setups it's common for the DNS server and router to share the same address (but don't count on it).There are various ways to find this information, but the easy way to find the router address isby selecting 'Built-in Ethernet' in the 'System Preferences, Network' screen above. Here, my router is at 10.0.1.1 and my subnet mask is 255.255.255.0:

Yet another way, which also tells you the DNS address, is using the command ipconfig getpacket en0:

The line with 'server_identifier' shows the gateway address, and the one with 'domain_name_server' shows the DNS address. In this case they are both 10.0.1.1.

The CentOS installer applies these settings for you, but you can edit them later in the CentOS 'System Settings, Network' screen:

Install Oracle

If you set up NFS, then you can download and unzip Oracle on the Mac, into a directory you share using NFS(www.oracle.com, Downloads, look for Database 10g for Linux, 32 bit).3 While it's downloading, it might be a good time to install your favourite Firefox bookmark synchronisation service - I use Foxmarks. Then within CentOS you can simply cd to that directory and execute ./runInstaller.Otherwise, you'll have to download Oracle from inside CentOS.You might as well also download the Oracle Database 10g Companion CD while you're at it (672 MB) if you are going to want to install Application Express later.

There isn't much I can add to Howard Rogers' guide to installing Oracle 10g Release 2 on Centos 4.3 & 4.4.Follow that. It'll work.

I also added the following to /etc/bashrc for a more friendly prompt:

This sets the prompt as the current directory name, in bold.

OEM has to be started manually:

Howard suggests editing /etc/rc.d/init.d/dbora (the database startup script called during the boot process) to have itstart up OEM. I had mine start up iSQL*Plus (see below) as well. I added the following lines to the 'start' section:

Note the URL displayed on the command line when you call emctl, which is http://hostname:1158/em/console/aboutApplication, where hostname is the name you set when installing Centos.You can actually control-click this URL and it will load in Firefox.However, it is rather more useful to be able to do this from the Mac.

Add an entry to the Mac's /etc/hosts file to map a name to the address, for example:

Now we can enter the Enterprise Manager URL into a browser, and behold the moment of truth:

Back on the Mac - SQL*Plus, gqlplus, SQL Developer etc

Oracle 10g Instant Client for Mac OS X

Although the RDBMS software itself won't run on Intel Mac, it turns out that SQL*Plus does.The client software will also allow other applications to connect to the database.

Find 'Macintosh OSX' and download both the Basic and SQL*Plus packages from the Instant Client downloads page.
Move the contents of both into a single convenient folder (I used /Applications/Application_folders/instantclient).
Add the location to your PATH variable, and also set DYLD_LIBRARY_PATH to point to it; for example:
Fire up SQL*Plus, using the fully-qualified host and service names:
Here's a rather basic shell script for starting SQL*Plus. Save the following in convenient directory and name it sql. (If you're worried that someone might snoop your password by entering ps -auxU williamr | grep sqlplus, or if you want to allow for multiple VMs, it'll take a bit more work). A marginally more flexible version is here. (It assumes you have gqlplus - see below.)

gqlplus

This gives a better SQL*Plus command-line experience (or should do). To quote the documentation:

gqlplus is a UNIX front-end program for Oracle command-line utility sqlplus. gqlplus is functionally nearly identical to sqlplus, with theaddition of command-line editing, history, table-name and optional column-name completion. The editing is similar to tcsh and bash shells.

Unfortunately I've found gqlplus isn't perfect - for example if you edit the current buffer by typing ed (with _EDITOR defined as vim or whatever)it wrecks the formatting by stripping all the leading spaces, and also strips any trailing semicolons, thus wrecking PL/SQL.ed also doesn't recognise the ORACLE_PATH environment variable and therefore doesn't find my scripts, although mysteriously they run fine.Maybe this is a configuration issue and as usual I'm just missing something. I'll update this page if I figure out how to fix it. Even so, it's a handy thing to have.

You can install it in CentOS if you like, but it'll run in a Mac Terminal window. You need the Oracle Instant Client set up first as it will look for a sqlplus executable.

Download gqlplus (zipped tarfile). The instructions tell you how to unzip (gunzip filename) and untar (tar -xvf filename), but this is a Mac and I let Firefox do it for me.
The download includes a README file with installation instructions, but essentially you open a Terminal window, cd to the unzipped gqlplus directory, and enter:

Now you can call gqlplus in place of sqlplus. It seems to take a little longer to start up, but it's worth it for the ability to scroll back throughprevious commands as you can on Windows.You could call this using a slightly modified version of the above script, sql.

iSQL*Plus

Although the server process is started by default when you create the database, it will need to be restarted any time you restart the database.Enter the following command in CentOS, as the oracle user:

One annoyance I've found with iSQL*Plus is that the font for the work area is the default proportional one, which (fairly obviously, I would have thought) isunsuitable for entering code. However, if you view the source of the page you can find the name of the stylesheet, which is

For Internet Explorer it is blaf-A0-en-ie-5-macos.css. The 'mozilla' one appears to be the default and is used in non-Mozilla based browsers such as Safari and Shiira.You can edit this file, and add the following lines at the end (while I'm at it I'll also make any DBMS_OUTPUT text monospace):

You can alter the session timeout interval from its default of 15 minutes by editing$ORACLE_HOME/oc4j/j2ee/oc4j_applications/applications/isqlplus/isqlplus/WEB-INF.

Note also that the traditional glogin.sql in $ORACLE_HOME/sql/admin is read by iSQL*Plus on startup and reconnection,so you can add things like set serveroutput on size unlimited here. (The documentation suggests that'Some privileged connections may generate errors if SET SERVEROUTPUT or SET APPINFO commands are put in the Site Profile or User Profile', although I'm not sure whatsort of errors it means, or whether they are severe enough to offset the benefit of not having to retype the command manually each time.)

Anyway, once the server process is running, enter http://hostname:5560/isqlplus in your browser (substituting your VM's hostname).iSQL*Plus is documented in the SQL*Plus User's Guide and Reference.

SQL Developer

Download from www.oracle.com/technology/products/database/sql_developer.A ready-to-run Mac OSX binary is provided (SQLDeveloper.app). I must admit I was expecting some clunky Windows Java port, but I was pleasantly surprised.The Preferences are in the wrong place, but apart from that it's looking a lot like a real Mac application. Nice job, guys!More resources are available on the official SQL Developer mini-site.I won't repeat the 'Getting Started' instructions here, as it's just a case of clicking on the icon.

Application Express

Simple, you might think

Start at the Application Express home page,which has many useful links including the download page,which in turn leads to the installation guide.

Essentially there are three steps:

Install Oracle HTTP Server (also referred to as 'Apache Standalone'), a lightweight web server, from the Companion CD (not actually a CD, but a zipped download).
Run SQL*Plus script apexins.sql as SYS to install the database objects (this will create two schemas, with various tables, packages, public synonyms etc).
Work through the Post-Installation Tasks in the installation guide, such as setting up a marvel.conf and starting the Oracle HTTP Server.

However in practice things were not quite so straightforward.
