Considerations for database sharing

In general, like any other unload utility during reorganization, FABHURG1 and FABHFSU must have exclusive control of the database while they run. In some cases, however, you might want to read the database while it is being updated by IMS.

The update might be done either by IMS within the same program or by another IMS subsystem through concurrent execution. For such cases, see Database sharing support. The considerations in the topic also apply to FABHURG1 and FABHFSU.
