Specifying the JDK or JRE for Integration Server

Integration Server must point to a JDK or JRE. By default, Integration Server points to the location of the JDK installed at the same time you installed Integration Server. If necessary, you can specify a different location.

Before you specify the location of Java for Integration Server, determine whether you need to specify the location of the JDK or the JRE. If you intend to use Designer to develop and compile Java services on Integration Server, specify the location of the JDK. If you will not be using this installation of Integration Server to compile Java services, you can specify the location of a JRE.

Important:
If you specify a different JDK or JRE, do not remove the JDK or JRE that Software AG Installer installed with Integration Server. The JDK and JRE installed with Integration Server are required to run the Software AG Uninstaller.

Note:Microservices Runtime does not use the Java Service Wrapper, the wrapper.conf file, or the custom_wrapper.conf file. To change the Java location s for Microservices Runtime, use a text editor to open Integration Server_directory /bin/setenv.bat(sh) and set the JAVA_DIR property to the JDK or JRE location.

1. Open the custom_wrapper.conf file in a text editor. You can find the wrapper.conf file in the following location:

2. Add the wrapper.java.command property and set it so that it specifies the location of the JDK or JRE installation directory. For example:

Note:
If your Integration Server runs on a UNIX system, you must also modify the library path property so that it points to the location of the JDK or JRE installation directory. Library path is represented by LIBPATH on AIX and LD_LIBRARY_PATH on all other flavors of Linux.

Note:
If you change the Java location and you use Integration Server to develop and compile Java services, you must also change the value of the watt.server.compile configuration parameter. For more information about watt.server.compile, see Server Configuration Parameters.
