This subsection explains the initialization procedure to be used when the configuration of the target system is changed. If you are changing the configurations of both the source and target systems, see 6.8.2 Changing the configuration of the source system for details about the initialization procedures.

The following figure shows the initialization procedure.

Figure 6-26 Procedure for changing the configuration of the target system

Note:

You must start the source and target databases to perform the steps beginning with step 5.

The procedure for changing the configuration of the target system shown in the figure is explained below. The numbers correspond to the numbers in the figure.

1. Terminate the source Datareplicator.
   

   No.	Task	Execution command	Check item
   1	Terminate the source Datareplicator.	hdestop	--
   2	Verify that the source Datareplicator has been terminated.	hdestate	Verify that the KFRB04411-E message has been output to the standard error output.

   --: Not applicable

2. Verify that all update information in the target Datareplicator has been imported.
   

   No.	Task	Execution command	Check item
   1	Verify that all processes are running at the target Datareplicator. If there is any inactive process, restart it.	hdsstate	Verify that PID in the displayed results is not -1.#
   2	Verify that all update information has been imported.	hdsstate	Verify that current used ratio in the displayed results is 0%. Alternatively, verify that Queue write position and Queue read position in the displayed results indicate the same position.

   #

   If sendmst is specified in the sendcontrol operand in the extraction system definition, -1 might be displayed in PID:hdstcpmst in COMMUNICATION INFORMATION.

3. Terminate the target Datareplicator.
   

   No.	Task	Execution command	Check item
   1	Terminate the target Datareplicator.	hdsstop	--
   2	Verify that the target Datareplicator has been terminated.	hdsstate	Verify that the KFRB04302-E message has been output to the standard error output.

   Legend:

   --: Not applicable

4. Change the system configuration.
5. Initialize the target Datareplicator.
   

   No.	Task	Execution command	Check item
   1	Initialize the target Datareplicator.	hdsstart -i -q#	Verify that the KFRB04216-I message has been output to the standard output (Event Viewer in Windows).

   #

   If necessary, specify options.

6. Start the source and target Datareplicators.
   

   No.	Task	Execution command	Check item
   1	Start the target Datareplicator.	hdsstart#	Verify that the KFRB00100-I message has been output to errfile1 or errfile2.
   2	Start the source Datareplicator.	hdestart#	Verify that the KFRB00502-I message has been output to msterrfile1 or msterrfile2.

   #

   If necessary, specify the options.
