APAR status

• Closed as program error.

Error description

• When a view is created on a base object, such as a table or
  another view, there is a set of privileges granted by the
  database manager to the definer of the dependent view.  If the
  AUTO_REVAL database configuration parameter is set to IMMEDIATE,
  then system privileges are supposed to be re-granted for the
  owner of the view when the base object is recreated, however,
  they are not.
  

Local fix

• Set AUTO_REVAL database configuration parameter to DEFERRED
  while performing maintenance on objects.  Otherwise, recreate
  the dependent view to pick up the correct system granted
  privileges.

  * All DB2 Version 9.7 GA through to Fix Pack 1 servers on      *
  * Linux, Unix and Windows environments running with AUTO_REVAL *
  * set to IMMEDIATE.                                            *

  * PROBLEM DESCRIPTION:                                         *
  * System privileges on views dependent on base objects do not  *
  * have privileges re-granted when the base objects are         *
  * redefined.                                                   *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * Set AUTO_REVAL database configuration parameter to DEFERRED  *
  * while performing maintenance on objects.  Otherwise, ensure  *
  * to always drop and recreate dependent views when base        *
  * objects are redefined, or apply DB2 Version 9.7 Fix Pack 2   *
  * to obtain the fix.                                           *
