Subsystem records (SSYS)

The RECON data set uses the subsystem (SSYS) record to describe data sharing information.

An SSYS record is created when an IMS subsystem signs on to DBRC. This SSYS record contains information about the subsystem and related recovery information including:

• Subsystem name and type (online or batch)
• IRLM identification
• Abnormal-end flag and the recovery-process start flag
• List of authorized databases
• Time stamp that correlates the subsystem entry with the appropriate log records
• A flag indicating whether this is a BPE-based subsystem
