  ****************************************************************
  DB2 was started with DEFER ALL to recover the DSNDB01.DBD01
  table space. The RECOVER utility with the PARALLEL option
  specified to recover table space DSNDB01.DBD01 triggered the
  trusted context cache to be built, which resulted in the
  message like the following:
      DSNT376I CORRELATION-ID=022.TCCBLD02 RC00C900BA TYPE2000
  This occurred in a disaster recovery situation after the
  clusters for the directory and catalog objects were deleted
  and defined.
  
  The trusted context cache build service tried to access the
  trusted context catalog tables to build the cache, which
  requires access to DSNDB01.DBD01. However, the RECOVER utility
  had previously acquired a drain of all readers and writers on
  DSNDB01.DBD01, this resulted in the timeout condition.
  

Problem conclusion

Temporary fix

Comments

• The trusted context cache will not be built if the DB2
  subsystem has been started with the DSNZPARM option to
  DEFER ALL objects. Hence, trusted connections will not
  be available.
