What are the recovery implications of SYSB-II?


CICS creates log entries for files defined as recoverable. Because SYSB-II makes batch appear like any other CICS transaction, SYSB-II can make use of these log entries for recovery from a batch job-step abend. SYSB-II also has a backward recovery option that allows you to back out all of the updates that a batch job step just made. The backward recovery option uses special batch logs for easier batch restarts.

As you might know, you can do forward recovery for online updates using a product like CICS VSAM Recovery. You can also do forward recovery for batch updates using that type of product and SYSB-II because batch changes are now logged in CICS.
