Error description

  • Java APAR IZ66459 provided a modification to the Java 5 JVM
    to prevent an 0C4 when a thread other than the IPT was
    executing and the IPT was no longer present within the LE
    enclave.
    .
    This APAR is raised to make sure that behaviour is in effect
    for all CICS JVMs.

  • ****************************************************************
    * USERS AFFECTED: All CICS TS 3.2 Users.                       *
    ****************************************************************
    * PROBLEM DESCRIPTION: When running a JVM an ABEND 0C4 may     *
    *                      occur when a thread other than the IPT  *
    *                      is executing and the IPT is no longer   *
    *                      present within the LE enclave.          *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    Java APAR IZ66459 provides a fix to the problem that when
    CICS runs a JVM there is the risk of an 0C4 abend should a
    thread other than the IPT be executing and the IPT is no longer
    present within the LE enclave.
    This fix is not active by default and CICS may still run the
    JVM with the same risk unless the JVM is configured correctly.
    

Problem conclusion

  • CICS is changed to ensure all JVMs start with the fix from
    Java APAR IZ66459 active.
