Stop database activity for the registered source or sources for which you want to suspend capture registrations.

To suspend the capture registrations, use the PWXUCREG utility to issue the SUSPEND_REGISTRATION command.

The suspension window opens. The utility sets the suspension timestamp to the current system time without any adjustment for the local time. Also, the utility issues message PWX-03716 to the DTLLOG log to report the registration status change.

For each suspended registration, the PowerExchange Navigator Resource Inspector displays

Suspended

in the

Status

field and the suspension timestamp in the

Suspend Time

field. The

Suspend Time

value is not adjusted for the local time.

For Adabas sources only, perform a PLOG switch.

This step ensures that all of the changes up to the point of the PLOG switch are captured for the active registration.

Enter the ECCR REFRESH command with the MVS MODIFY (F) command:

The ECCR becomes aware of the registration status change and suspension timestamp. When the ECCR encounters the first change record to discard, it issues message PWX-07752. The ECCR discards change records that have a timestamp later than the suspension timestamp.

Run the jobs or processes that generate the changes that you do not want to capture for the source or sources that are associated with the suspended registrations.

To reactivate the capture registrations, use the PWXUCREG utility to issue the ACTIVATE_REGISTRATION command.

The suspension window closes. The utility sets the activation timestamp to the current system time without any adjustment for the local time. Also, the utility issues message PWX-03716 to the DTLLOG log to report the registration status change.

For each reactivated registration, the PowerExchange Navigator Resource Inspector displays

Active

in the

Status

field and the activation timestamp in the

Active Time

field. The

Active Time

value is not adjusted for the local time.

For Adabas sources only, perform a PLOG switch.

This step ensures that all of the changes that occur during the suspension window up to the PLOG switch are discarded for the suspended registration.

Enter the ECCR REFRESH command with the MVS MODIFY (F) command again.

The ECCR becomes aware of the registration status change and activation timestamp.

Enable database activity to resume on the registered source or sources.

The ECCR starts capturing change records that have timestamps later than the activation timestamp. The ECCR issues message PWX-07753 when it encounters the first change record in the change stream after the end of the suspension window.
