Pre-installation tasks

Before you install, you might need to prepare or configure your computer.

For developing Java applications, you must install Eclipse IDE for Java Developers for Eclipse 2023-06. This can be downloaded from https://www.eclipse.org/downloads/packages/release/2023-06/r/eclipse-ide-java-developers. You can use the Eclipse installer to downloaded it automatically.
For developing Java and Web applications, you must install Eclipse IDE for Enterprise Java and Web Developers for Eclipse 2023-06. This can be downloaded from https://www.eclipse.org/downloads/packages/release/2023-06/r/eclipse-ide-enterprise-java-and-web-developers. You can use the Eclipse installer to downloaded it automatically.
Access to a repository containing the DMA update site. This can either be a locally downloaded zip file or the address of a shared repository that has been preconfigured for your usage.

Note: You can download the DMA update site zip file from IBM Site.
A valid license. This can either be provided by means of a license server that contains DMA licenses, or it can be a license key (permanent or trial) which you have obtained from IBM.
An installation of a Java development kit (JDK) 64 bit.

Note:
DMA requires a Java 17 JDK, both when installing and running it. We recommend using the Open JDK or Oracle JDK (see the System Requirements for the exact recommended versions.)

You should specify which JDK to use by editing the file eclipse.ini (found in the Eclipse installation folder). Specify the path to your JDK 17 installation using the -vm argument. For example:

-vm

D:/openjdk-17/jdk-17/bin/server/jvm.dll
For Mac, add the below entry to config.ini file to provide non-root user access to var directory for DMA license plugins to access:
```
com.ibm.cic.licensing.p2.home.dir=/var
```
