The DB2 ECCR displays a DB2 unit‑of‑recovery ID (URID) and an internal status code for each unit of recovery (UR) that is active at the time you issued the
F DB2
eccr‑name
,URID
command. The DB2 URID is the same as the PowerExchange Logger unit of work (UOW).
This message can also be generated during Statistics and Refresh processing.
This message contains the following variables:
  • 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 Logger for MVS.
    • 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
    • Data
    • Abort UOW
    • Begin Phase1
    • End Phase1
    • Begin Phase2
    • Phase 1/2 Tran
    • End Todo
Processing continues.
Use this information to diagnose problems with UOWs that do not end properly, such as persistent outstanding UOWs.
If the message displays a valid
urid
value, you can use the DB2 ECCR TERM command to commit the UR. If the message reports a URID value of PENDING, you must use the Logger RESOLVE_INDOUBT command to commit or discard the UR. In this case, the next time the DB2 ECCR is restarted, it receives the result of the RESOLVE_INDOUBT command. After the restart, the resolved entries no longer show up in the output from the URID command and do not affect the restart point for the DB2 ECCR.
