PM69387: STORAGE OVERLAY WRITING DATA TO DRLDUMP CAUSES ABENDS SUCH AS S30A RC24 ( ABEND30A ABENDS30A S30A 30A )

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• A collect ( DRLPLC )is being run with the "ON OVERFLOW CONTINUE"
  option and overflow conditions are occurring. This causes some
  diagnostics to be written the DRLDUMP file. In some cases the
  combined length of the column and table names involved causes
  the length of the diagnostic line to exceed 80 bytes.
  Because no LRECL has been specified for DRLDUMP it defaults to
  80 bytes and the diagnostics are being truncated.  For example
  .
  "Column IO_WAIT_DB_EVENTS in table DB2_TRANSACTION_M is set to
  null due to overflow"
  .
  in truncated by 2 bytes to become:
  "Column IO_WAIT_DB_EVENTS in table DB2_TRANSACTION_M is set to
  null due to overfl".
  If the DRLDUMP record is followed immediately by a CICB prefix
  for an area to be freed ( the length of the storage to be freed
  is at X'02' in the CICB prefix) an S30A abend with return code
  24 will result.  The abend code may be different depending on
  the storage which gets overlaid by the DRLDUMP record which
  exceeds 80 bytes in length.
  .
  See LOCAL FIX for work around.
  

Local fix

• To avoid the overlay, explicitly specify an LRECL larger than
  80 bytes for DRLDUMP in the DRLPLC JCL, for example:
  .
  //DRLDUMP  DD SYSOUT=*,LRECL=121
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of the TDS/z log collector,        *
  *                 particularly those specifying the            *
  *                 ON OVERFLOW CONTINUE option on the COLLECT   *
  *                 statement.                                   *
  ****************************************************************
  * PROBLEM DESCRIPTION: Abend S30A-10 during freemain. Other    *
  *                      abends such as S878-18 (error during    *

  *                      block overlay) are also possible.       *
  *                      If ON OVERFLOW CONTINUE is specified    *
  *                      then DRLOUT may contain message         *
  *                      DRL0349W and DRLDUMP may contain        *
  *                      truncated diagnostics for columns with  *
  *                      overflow errors.                        *
  ****************************************************************
  * RECOMMENDATION: APPLY THE PTF FIXING THIS APAR               *
  ****************************************************************
  The diagnostic writer does not check the length of the
  diagnostic message to be written resulting in overlays from the
  I/O buffer into storage control blocks later used to free
  storage or perform other system functions.
  

Problem conclusion

• The diagnostic lines causing the problem have been reformatted
  to not exceed 80 bytes. The diagnostic writer has been modified
  to wrap text that exceeds the LRECL specified for DRLDUMP.
  TDS/z documentation will be updated to recommend a minimum
  logical record length of 80 for DRLDUMP.
