Eligible User Image Copy
Although you can create User Image Copy at any time, not all User Image Copies are eligible for database recovery.
With the Build Recovery JCL Only option, you can check whether
the User Image Copy is eligible without updating existing DBDS. IMS Recovery Expert
checks ALLOC, REORG, and other records in the RECON data set and determines whether
the User Image Copy is eligible for database recovery. The cases where the User
Image Copy is not eligible are listed below.
- REORG after User Image Copy
- If the REORG record exists between UIC RUN
timestamp and Recovery Timestamp,
it is impossible to recover the DBDS from the User Image Copy. If this
condition is detected, the following message is displayed, and the
recovery job terminates with an
error.
BSY0004I - (BSYI540E)- REORG after UIC found, UIC cannot be used for recovery: DB=dbdname DDN=ddname
- Index DBDS in HALDB
- Due to the DBRC NOTIFY.UIC command restriction, ILDS and index DBDS in HALDB cannot be used as User Image Copy. IMS Recovery Expert schedules index rebuilding instead of recovery.
- HALDB Online Reorganization
- Due to the DBRC NOTIFY.UIC command restriction, User
Image Copy is not allowed while Online Reorganization is in progress. If
this condition is detected, the following message is displayed, and the
recovery job terminates with an
error.
BSY0004I - (BSYI538E)- UIC was taken while OLR was in progress: DB=dbdname DDN=ddname
- CIC User Image Copy for KSDS DBDS
- Due to the DBRC NOTIFY.UIC command restriction, CIC
User Image Copy is not allowed for KSDS. If this condition is detected,
the following message is displayed, and the recovery job terminates with
an
error.
BSY0004I - (BSYI539E)- UIC was created in ALLOC time range, CIC is not allowed for KSDS : DB=dbdname DDN=ddname
