Problem summary

  • ****************************************************************
    * USERS AFFECTED:                                              *
    * This issue may affect you if you are using IDR Db2 for z/OS  *
    * remote source.                                               *
    ****************************************************************
    * PROBLEM DESCRIPTION:                                         *
    * When the Db2 log reader API returned a decompression error,  *
    * the CDC engine stopped reading logs for tables in all        *
    * subscriptions. Now, the CDC engine logs an error indicating  *
    * which table and position had the decompression error and     *
    * stops the subscriptions that replicate that table. Other     *
    * subscriptions remain running.                                *
    ****************************************************************
    * RECOMMENDATION:                                              *
    * Upgrade to IDR 11.4.0.3-5590 or newer for Db2 for z/OS       *
    * remote source.                                               *
    ****************************************************************
    

Problem conclusion

  • Upgrading to IDR 11.4.0.3-5590 or newer for Db2 for z/OS remote
    source resolves the issue.
