PM36177: ADD NEW SUBSYSTEM PARAMETER (ZPARM) AS TIME OUT FACTOR FOR DDL AND DCL

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• During the processing of a DDL statement, DB2 uses the standard
  IRLM time out value for obtaining locks.  This limits user
  flexibility on controlling how long DDL statements will wait for
  a resource before timing out.
  .
  To allow user more control on the wait time for a resource
  during the processing of a DDL statement before a time out is
  encountered, we would like to introduce a separate time out
  factor for DDL and DCL (GRANT, REVOKE, and LOCK) statements.
  New subsystem parameter (ZPARM) will be added in order to
  influence the timeout value.
  .
  The actual time out value will be the product of new parameter
  and the standard IRLM time out value that is in effect as
  specified by IRLMRWT.
  
  influence the timeout value.

Comments

• This is the V10 change for APAR PM32921.
  
  This fix is an enhancement to allow a user more control on the
  wait time for a resource during the processing of a DDL
  statement before a timeout is encountered.
  
  ++HOLD Type MTS
  **Action for PM36177
  PM36177 is a pre-conditioning APAR that includes changes to
  support the enhancement for IRLM timeout value for DDL
  statements that will be enabled via APAR PM37660. At this
  time, all of the changes are transparent to the user. In a
  data sharing group, this pre-conditioning APAR should be applied
  to all members before the enabling APAR is applied to any
  member. The enhancement is not enabled until the enabling APAR
  is applied.
