The RESET function releases the Directory (CXX) and database control or resets the Log Area (LXX) to empty. The two functions are described separately following.
This function clears the update-user control count, read-only-user control count, and Directory (CXX) exclusive control indicator. The function forces subsequent CA Datacom/DB processing to assume no other CA Datacom/DB processing is active.
Important! Use this function only when no other CA Datacom/DB processing is active. If this function is run and CA Datacom/DB jobs are active, the processing that occurs after this point produces unpredictable results.
If a DBUTLTY RESET AREA=CXX,DBID=nnn is performed after a MUF failure and prior to MUF RESTART processing, the RESTART phase of the next Multi-User Facility start up ignores any log records that pertain to that DBID. Should this occur, your data integrity on this DBID may be compromised.
