DFS0485W RECOVERY DATA FOR [DATA BASE dbdname|AREA areaname] MISSING FROM THE RECON DATASET
Explanation
Recovery information for database dbdname or area areaname might be missing from the RECON data set. The database or area is being opened for update with DBRC so that log data sets generated during the execution are recorded in the RECON data set. In a previous run when update ACCESS to the database or area was allowed, DBRC was not used. Therefore, unless explicit action was taken, the RECON data set contains no record of log data sets from previous executions necessary to generate valid recovery JCL.
If the log data sets from the previous executions were explicitly added to RECON, then this message confirms that the RECON is again being used to record recovery information. If an image copy was recorded in RECON since the last update of the database or area that did not use DBRC, and if the log data sets from the previous executions were not recorded in RECON, then this message indicates that recovery from image copies before the updates without DBRC are invalid.
System action
Execution continues. The DBRC usage indicator (DUI) in the database is updated with the identification of the RECON data sets that currently record recovery information.
Programmer response
- Use the appropriate DBRC commands to manually update the RECON data set to ensure that all logs required as input for recovery or change accumulation are recorded.
- Take and record an image copy of the database (or area) in the RECON data set to provide a new recovery base.
The first execution that opened this database or area for update processing without DBRC issued message DFS0486W.
