DSNU521I csect-name - RECOVER UTILITY FAILED. UNABLE TO READ REQUIRED LOG RECORDS.
Explanation
Recovery was requested for a table space, index space, or data set. An attempt was made to apply changes from the Db2 log, but the necessary log records could not be read from the log data set. This message is accompanied by message DSNI007I.
System action
The RECOVER utility completes unsuccessfully with return code 8.
Operator response
Provide the console listing of the DSNI007I message for the system programmer.
System programmer response
Run the print log map (DSNJU004) utility. Find the data set that contains the requested RBA or LRSN from the output of the utility.
User response
Consult the system programmer for corrective action.
Problem determination
- The data set was deleted from the bootstrap data set (BSDS) by the change log inventory (DSNJU003) utility. Rerun the utility to insert the missing data set name. Db2 must be stopped to run this utility.
- The BSDS was damaged. The BSDS can be restored using the dump and the most recent archive log data set. Run the change log inventory (DSNJU003) tility to supply changes that occurred during and after the last offload operation. Changes can be determined from the operator's console listing.
If a listed log data set contains the required RBA or LRSN, this message is preceded by one or more DSNJxxx error messages. See the explanation of those messages for the appropriate action.
