Environment

This command can be issued from a z/OS® console, a DSN session under TSO, a DB2I panel (DB2 COMMANDS), an IMS or CICS® terminal, or a program that uses the instrumentation facility interface (IFI).

This command must be issued from the source or proxy data sharing group in an implementation of the GDPS® Continuous Availability with zero data loss solution.

Db2 commands that are issued from a logged-on z/OS console or TSO SDSF can be checked by Db2 authorization using primary and secondary authorization IDs. A logged-on z/OS user ID must be defined in RACF or a similar security server.

Usage notes

Trace information for data sharing members

When this command with group scope is issued in a Db2 data sharing member, it also runs on all other active members. IFICID 090 trace records for other group members can show that the same command was issued by the SYSOPR authorization ID from the 016.TLPKN5F correlation ID, in addition to the trace records from the member where the original command was issued. See Command scope in Db2 data sharing.
