URID Command

Lists the DB2 URIDs for the DB2 subsystem or data-sharing group on which the DB2 for z/OS ECCR is running. Reports only the URIDs for active URs.

A DB2 UR, if captured, can also be an outstanding PowerExchange Logger UOW.

Use this command to diagnose problems, such as unsuccessful QUIESCE operations or persistent UOWs that do not end.

Syntax

Use the following command syntax:

URID

To issue the ECCR URID command, use the MVS MODIFY or F command with the ECCR started task or job name.

Output

The command produces the following message:

PWXEDM177438I urid status last activity at last_log_position is activity_type

In this message:

urid is the DB2 unit-of-recovery ID (URID) for the UR.

status is one of the following values:

ABORT. The UOW was aborted, and no change data is available to capture.

OPEN. Change data is available to capture, but no Begin UOW record has been received.

POTENTIAL. The Begin UOW was received, but no change data is available to capture yet.

ROLLBACK. The UOW was rolled back, but change data is available to capture.

TRANSMIT. The DB2 ECCR is sending change data for this UOW to the PowerExchange Logger for z/OS.

UNRESOLVED. No urid value was encountered during the DB2 ECCR run. The ECCR records a URID value of PENDING for the specified UOW. When a UOW is outstanding, PowerExchange issues message PWXEDM177440W. This situation can occur if in‑flight units of work exist when the previous occurrence of the DB2 ECCR is shut down, usually not with a QUIESCE.

last_log_position is the RBA or LRSN of the last record that was processed for this UOW.

activity_type is one of the following values:

Begin UOW

End UOW
