Initializing the VSAM Data Set as a Dump Directory

After you create a new dump directory VSAM data set, you must initialize it for IPCS. Use the TSO/E IPCSDDIR command as follows:

IPCSDDIR 'userid.DDIR'

Note: You do not need to initialize your dump directory for each IPCS session.

If the initialization is successful, the system displays READY.

The IPCSDDIR command writes two records to the dump directory: one with a key of binary zeros (0) and the other with a key of binary ones (1).
