Usage notes

1. We cannot use COPYPAGE on page sets of a queue manager that is running.

2. Using COPYPAGE involves stopping the queue manager. This results in the loss of nonpersistent messages.

3. Before you use COPYPAGE, the new data sets must be preformatted as page sets. To do this, use the FORMAT function, as shown in Figure 55.

4. Ensure that the new (destination) data sets are larger than the old (source) data sets.

5. We cannot change the page set identifier (PSID) associated with a page set. For example, we cannot 'make' page set 03 become page set 05.

6. Failure of this function does not prevent other CSQUTIL functions from being attempted.

7. If you attempt to use the COPYPAGE function after the queue manager has terminated abnormally, the page sets might not have been closed properly. If a page set has not been closed properly, we cannot successfully run the COPYPAGE function against it.

   To avoid this problem, run the AMS VERIFY command before using the COPYPAGE function. The AMS VERIFY command might produce error messages. However, it does close the page sets properly, so that the COPYPAGE function can complete successfully.

   For more information about the AMS VERIFY command, see the DFSMS/MVS Access Method Services for VSAM or the DFSMS/MVS Access Method Services for the Integrated Catalog Facility manual.
