Space Requirements for Using the Backup Feature

The PDS containing the initialization parameters must have enough directory and disk space for the following items:

  • The backup members for the global initialization parameter file and local initialization parameter files
  • Changes to the global and local initialization parameters
  • ISPF formatted statistics

If the initparm PDS runs out of space, an Sx37 (or similar) ABEND occurs and the system attempts to back out the changes by copying the initparm backup file (including the ISPF STAT information). To recover space inside the PDS, compress the PDS prior to starting IBM® Connect:Direct®.
