PH33238: DSMAX REACHED AFTER PH27493 / UI71764 IS APPLIED FOR A COPY SHRLEVEL REFERENCE JOB WITH RC00C20113 21/01/11 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• DSMAX reached after PH27493 / UI71764 is applied for a COPY
  SHRLEVEL REFERENCE job of a list of 4285 tablespaces or
  partitions with :
  
  DSNT500I <DBU2 DSNUGRAR RESOURCE UNAVAILABLE
            REASON 00C20113
            TYPE 00000220
  
  Additional symptoms: RC00E4010A 00E4010A MSGDSNT500I
  

Local fix

• Use COPY SHRLEVEL CHANGE and OPTION(ITEMERROR,SKIP) to
  avoid having all the tablespaces in the list opened at
  once.

  ****************************************************************
  With PH27493/UI71764 applied, COPY utility job may end with
  ABEND04E RC00E4010A due to table space or index open failure
  with RNA reason code RC00C20113, when the open dataset count
  exceeds the DSMAX.
  The dataset close processing logic has been improved to
  proactively close datasets that were opened solely for
  utility access in PH27493. When approaching DSMAX or when
  DSMAX is reached, Db2 will prioritize the closure of
  utility-only datasets over those datasets that have been
  accessed by applications.
  However, the utility-access-only datasets are excluded from
  DSMAX processing mistakenly in the enhancement of PH27493.
  This causes the utility-access-only datasets to not be closed
  when DSMAX is being reached, and could therefore cause dataset
  open failures such as the ABEND04E RC00E4010A for the COPY
  utiility.
  

Problem conclusion

• Db2 code has been modified to include and prioritize the
  closure of utility-only datasets properly when approaching
  DSMAX or when DSMAX is reached.
