System/member information

z/OS MVS Using the Subsystem Interface
SA38-0679-00

In addition to the device information, the JES Device Information services returns basic information on JESPLEX members that match the system and member selection filters (see SSJD6SYS and SSJD6MBR in SSJDFLT6). Note that complete information on JESPLEX members is available from the JESPLEX information subfunction of the JES Property Information services (JESPLEX Information).

The JES Device Information services return one system/information data area in the SSJDSIN8 chain for each request to obtain device data. This data area contains an entry for each system/member that meets the selection filters. Each data area consists of the following contiguous data structures:
  • System information header mapped by JDSIHDR.
  • Prefix section mapped by JPSYSPRF in macro IAZJPLXI.
  • System information section mapped by JPSYSINF in macro IAZJPLXI.
