Just an FYI for which java versions to use.  It's a bit frustrating having to reinstall java 8 just to get the licensing installed (also a waste of time to figure out).

Hello Daniel... I'm facing with that about informix 14.10.FC13 installation... I want to update from informix1410FC11 to 1410FC13 but I don't know how to specify in the ids_install the JAVA_HOME to point java11 without desinstall java 8 because 1410FC11 is using it... do you know how to specify the path?

It does depend upon the your Java installation.  Some OS versions will allow the installation of multiple different java versions and they have a command that will point to your default version.

If you install your own version of Java like the Zulu OpenJDK from Azul, you can install multiple versions in /opt and then create a symbolic file link to point to the version you want to use.

Steps: Set JAVA_HOME, install your java versions, create link to the version you need.

Example:

Set JAVA_HOME to /opt/java.

Install zulu8.90.0.19-ca-jdk8.0.472-linux_x64 and zulu11.84.17-ca-jdk11.0.29-linux_x64

To link to Java8 run: ln -s  /opt/zulu8.90.0.19-ca-jdk8.0.472-linux_x64 /opt/java

To link to Java11 run: ln -s  /opt/zulu11.84.17-ca-jdk11.0.29-linux_x64 /opt/java

ls -al /opt     (shows link to java 11)

lrwxrwxrwx 1 root     root      36 Jan 20 14:37 java -> zulu11.84.17-ca-jdk11.0.29-linux_x64/
drwxr-xr-x 1 root     root     146 Oct  4  2025 zulu11.84.17-ca-jdk11.0.29-linux_x64/
drwxr-xr-x 1 root     root     236 Oct  4  2025 zulu8.90.0.19-ca-jdk8.0.472-linux_x64/

As you install different versions of OpenJDK you only need to change the link to point to the newer version.

Note:  You may need to recompile custom UDRs after changing the java version on a running system.
