About this task
Procedure
- Set the JVMPROFILEDIR system
initialization parameter to a suitable directory in z/OS® UNIX where
you want to store the JVM profiles used by the CICS region. For more information, see Setting the location for the JVM profiles.
- Ensure that your CICS region has
enough memory to run Java applications.
For more information, see Setting the memory limits for Java.
- Give your CICS region
permission to access the resources held in z/OS UNIX,
including your JVM profiles, directories, and files that are required
to create JVMs. For more information, see Giving CICS regions access to z/OS UNIX directories and files.
- Set up a JVM server. You can configure a JVM server to run different workloads. For more information, see Setting up a JVM server.
- Optional: Enable a Java security manager to
protect a Java application from performing potentially unsafe actions.
