Execute the pdstop command to terminate HiRDB normally.

Take the actions described below. Actions (b) and (c) can be taken in any order. For details about the HiRDB Datareplicator commands, see the HiRDB Datareplicator Version 8 Description, User's Guide and Operator's Guide.

(a) After HiRDB Datareplicator has extracted all system logs, wait for all the extracted system logs to be reflected onto the target database

For details about how to check whether all system logs have been extracted and whether all system logs have been reflected, see Modifying the Configuration of the Source System in the HiRDB Datareplicator Version 8 Description, User's Guide and Operator's Guide.

(b) Stop the data extraction facility of HiRDB Datareplicator

Execute the hdestop command to stop the data extraction facility of HiRDB Datareplicator.

(c) Stop the target Datareplicator

Stop the target Datareplicator. If the target Datareplicator is HiRDB Datareplicator, use the hdsstop command to stop it.

Move back the time in the OS settings. In the case of a HiRDB parallel server configuration, if the time differs among the individual server machines, certain tasks such as comparing messages become complicated. Therefore, synchronize the time among the server machines.

Wait for the amount of time by which the time was moved back (for example, 1 hour if the time was moved back by 1 hour).

Use the pdstart command to start HiRDB normally.

Take the actions described below. Actions (a) and (b) can be taken in any order.

(a) Start the data extraction facility of HiRDB Datareplicator

Execute the hdestart command to start the data extraction facility of HiRDB Datareplicator, which was stopped in Step (2) (b) above.

(b) Start the target Datareplicator

Start the target Datareplicator, which was stopped in Step (2) (c) above. If the target Datareplicator is HiRDB Datareplicator, use the hdsstart command to start it.

To acquire a log point, execute the database copy utility (pdcopy) with the -z option specified and acquire backups of all RDAREAs. To acquire backups of all RDAREAs in a HiRDB parallel server configuration, you must execute the pdcopy command with the -z option specified on each server.
