PM94429: ABEND04E RC00E20004 FROM DSNSVBK FOR THE ADMF LOCAL BCT SUBPOOL WITH FULL OF RCLS BLOCKS ACQUIRED BY DSNILSTS FOR START DATABASE

APAR status

• Closed as fixed if next.

Error description

• ABEND04E RC00E20004 from DSNSVBK for the ADMF LOCAL BCT SUBPOOL
  with full of RCLS blocks acquired by DSNILSTS for START DATABASE
  COMMAND. Due to the number of START command that was issued,
  DB2 has allocated too much storage. With this APAR, DB2 will
  only allow certain number of START or STOP DB command to avoid
  the storage shortage. With this APAR, DB2 will issue an error
  message to the user instead of ABEND.
  .
  For STOP DATABASE command, the structure observed was DBEE block
  acquired by DSNIDBPL in the same BCT pool
  

Local fix

• If the command uses SPACENAM(*) option, remove it. Without the
  SPACENAM, the customer could issue more number of STOP command.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: DB2 for z/OS users of -START or -STOP        *

  * PROBLEM DESCRIPTION: ABEND04E RC00E20004 DSNIDBAE DSNSVBK    *
  *                      below the bar storage shortage when     *
  *                      issuing many -START OR -STOP DATABASE   *
  *                      SPACE commands.                         *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When issuing many -START DB SP or -STOP DB SP commands,
  00E20004 storage pool ADMF LOCAL BCT SUBPOOL shortage may be
  encountered.  The storage contains many RCLS and/or DBET DBEE
  blocks.
  

Problem conclusion

Temporary fix

Comments

• Another APAR PI06843 moves the DBET storage in ADMF local BCT
  subpool to its own above the bar pool.  The APAR is strongly
  recommended to DB2 users to alleviate the storage constraint for
  -START and -STOP DB commands.  DB2 internal defect D175543 is
  opened to address RCLS storage usage in the next release of DB2.
