DELETE PSID

Usage notes for DELETE PSID

1. The identified page set must have no storage class (STGCLASS) referencing it.
2. If the page set still has buffers in the buffer pool when you issue this command, the command fails and an error message is issued. We cannot delete the page set until 3 checkpoints have been completed since the page set was emptied.
3. If the page set is not to be used again by the queue manager, update the queue manager started task procedure JCL, and remove the corresponding DEFINE PSID command from the CSQINP1 initialization data set. If the page set had a dedicated buffer pool, remove its definitions also from CSQINP1.
4. If you want to reuse the data set again as a page set, format it before doing so.
