This utility has many potential uses. For example, use it to suspend change capture while you make DDL changes such as cascade delete or delete all row changes or corrections to a source or target object.

This utility runs on z/OS only. It processes registrations only for data sources from which the following ECCRs capture data:

You can use the utility to perform the following tasks:

When you use the utility to change the registration status, it sets suspension and activation timestamps. The period bounded by the suspension and activation timestamps is called the

suspension window

.

You must refresh the ECCR after a registration status change to have it detect the status change and get the suspension and activation timestamps. During the suspension window, the ECCR discards change records that have a timestamp later than the suspension timestamp. The utility writes message output for registration status changes for audit and monitoring purposes.

The PowerExchange Navigator displays the current registration status in the

Status

field of the Resource Inspector. After the utility processes a PWXUCREG registration suspension request, the Resource Inspector displays the suspension timestamp in current system time in the

Suspend Time

field and displays the value

Suspended

in the

Status

field. After the utility processes a PWXUCREG registration reactivation request, the Resource Inspector displays the activation timestamp in the

Active Time

field and resets the

Status

to

Active

.
