APAR status

  • Closed as program error.

Error description

  • Every time a subscription is started, except the first time
    after an address space start, some storage is leaked. The amount
    of storage depends on how many table mappings are defined in
    the subscription.
    

Local fix

  • The address space can be restarted.
    

Problem summary

  • ****************************************************************
    * USERS AFFECTED: All users of IIDR CDC for z/OS               *
    ****************************************************************
    * PROBLEM DESCRIPTION: There exists a storage leak that after  *
    *                      a long time of operation may prevent    *
    *                      the product to obtain new storage in    *
    *                      order to function as designed.          *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When replication for a subscription is stopped and started, some
    storage used for performance metrics information is leaked. This
    will happen every time the subscription is restarted. After a
    time, this leak may lead to the address space exhausting the
    available storage and prevent it from functioning as designed.
    

Problem conclusion

  • A fix is implemented to ensure that storage used for performance
    metrics is not leaked.
