  • RPG/JAVA Integration how to define min and max size for started JVM?

    Hello all,

    we are using the RPG-JAVA Integration to use webservices through java code in RPG. One of the messages to process is rather big so we get a OutOfMemoryError...how do we set the min and max size of the heap in the started JVM?

    kind regards

    A standalone java program heap size can be tuned using -Xms and -Xmx
