Batch utilities
BCF provides batch utilities to help you handle specific situations that may arise in the batch backout and logging environment.
For more information about these utilities, see Using-the-log-utilities.
BCF Log utility
The BCF Log utility helps you analyze BCF operations.
You can also use it as an emergency solution to some recovery requirements, for example, to run the IMS Batch Backout utility and back out the complete execution of a job step when the application has used checkpoint calls but did not begin execution with a checkpoint call. You can also use it to perform backout for a batch message processing (BMP) execution because the IMS Batch Backout utility does not support complete backout for a BMP that has participated in sync point processing.
The BCF Log utility provides the following functions:
- statistics (STATS)
- logical compare (COMPARE)
- batch backout log create (BCREATE)
- online backout log create (OCREATE)
- find online BMP executions (FIND)
Database Changed Block Reconciliation utility
The Database Changed Block Reconciliation utility is an extension of the BCF Log utility.
You can use to identify database blocks that have been changed by more than one unit of work. The utility produces a report that lets you determine whether executing the Batch Backout utility using the log data set created by the OCREATE function of the BCF Log utility is likely to result in a damaged database.
