Use of QUIESCE on catalog and directory objects

Running the QUIESCE utility on the catalog and directory table spaces makes these objects unavailable for any updates during the utility execution. Therefore, this action can have a severe, adverse impact on your system's availability. Running QUIESCE on the catalog and directory table spaces is not necessary to prepare for point-in-time recovery. The RECOVER utility can recover data to a point in time with consistency without a quiesce point.

If system availability is not a concern or you have planned for it, and you want a quiesce point on the catalog and directory table spaces, run QUIESCE on these table spaces. Adhere to the following requirements:

You can quiesce DSNDB01.SYSUTILX, but DSNDB01.SYSUTILX must be the only table space in the QUIESCE utility control statement.
A separate QUIESCE control statement for DSNDB06.SYSTSCPY is required after you quiesce the other catalog and directory table spaces. This separate quiesce is needed to ensure that a subsequent point-in-time recovery of DSNDB06.SYSTSCPY recovers all of the SYSCOPY records for QUIESCE operations for the other catalog and directory objects.
