Supplementary usage topics

The topics in this section address supplementary usage topics that can affect the operation of IMS HP Change Accumulation Utility.

Reprocessing change accumulation groups
After a validation error, the IMS HP Change Accumulation Utility process stops. You can automatically reprocess change accumulation groups after a validation error by using the GEN.RETRY extended batch control statement.
Point-in-time change accumulation and database recovery
Point-in-time change accumulation (PITCA) and database recovery restores a database to a specific date and time. A point-in-time change accumulation is useful for contingency planning and for disaster recovery planning.
Using secondary logs
The IMS dual logging feature records logs in duplicate. The copy of each primary log is called the secondary log.
Limiting input logs
It is sometimes necessary to limit the number of log data sets that are processed.
Failure to start SORT subordinate address spaces
It is possible to receive an error message indicating a failure in starting the SORT subordinate address spaces.
Diagnosing ISPF errors
