Verifying your Java components installation

CICS® support for Java™ application programs is included in the base product, and no specific installation is required. Before you begin to set up and configure Java support in your CICS system, follow the steps below to verify that the Java components are correctly installed on your system.

  1. Use the supplied checklist in Verifying Java components checklist to ensure that all of the required Java components are installed in the correct locations on your CICS system.
  2. Read about the JVM components and the supplied sample definition files in more detail in Java Virtual Machine sample definition files, particularly if you have not performed a default installation.
  3. Authorize the hlq.SDFJAUTH library. See Authorizing the hlq.SDFJAUTH library for details on how to do this.
  4. Amend the default parameters in the BPXPRMxx members of SYS1.PARMLIB so use the JVM supplied with CICS. See Amending parameters in SYS1.PARMLIB(BPXPRMxx) for details on which parameters to change.

When you have verified your Java installation, use the task list in Java Applications in CICS to begin setting up your Java environment.
