Problem summary


    

  • ****************************************************************
* USERS AFFECTED: All users of QCF3.1. No abends or other      *
*                 errors. Some ECSA storages are not released  *
*                 at IMS shutdown and used ECSA builds up.     *
****************************************************************
* PROBLEM DESCRIPTION: Several QCF programs obtain ECSA,       *
*                      but do not release it properly at the   *
*                      end of IMS run. Programs are changed to *
*                      release the storage. No QCF ECSA shows  *
*                      anymore after IMS shutdown.             *
****************************************************************
* RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
****************************************************************
Programs are changed to release ECSA storage. Install the APAR
to avoid used ECSA storage building up.
