Specifying another JVM to launch Talend Studio

If you have more than one JVM installation on your machine, you can specify which one to use to launch Talend Studio for a particular purpose.

Before you begin

Download and install the JDK of the new Java version that you want to use.

Procedure

Go to the root of your Talend Studio installation directory and open the .ini file with a text editor.

For Linux, the file name is either Talend-Studio-linux-gtk-aarch64.ini or Talend-Studio-linux-gtk-x86_64.ini.
Edit or add the -vm option so it points to the Java executable of the JVM version with which you want to launch Talend Studio.
Make sure to follow these rules:
- The -vm option and its value must be on separate lines.
- The -vm option must be defined before the -vmargs option, because everything after -vmargs is passed directly to the JVM.
Example
For example:
```
-vm 
/usr/lib/jvm/<JDK_HOME>/bin/java
```
or
```
-vm
/usr/lib/jvm/<JDK_HOME>/lib/server/libjvm.so
```

Results

Next time you launch Talend Studio, it is using the new Java version. For more information, see Launching Talend Studio.

Then, if you want to check which JVM version Talend Studio is using, open the latest logs located in <workspace>/.metadata/.log. They will show you the Java version used. For example:

!SESSION <timestamp> -----------------------------------------------
...
java.version=17.0.10
java.vendor=Azul Systems, Inc.
