4.2.7 Changing the Data Insertion Destination Director

If multiple directors are being used, it is possible to change which director is used to insert data from APIs.

This section explains how to change the director where data is inserted from APIs.

The following diagram shows an example of an operation pattern where data is managed so that data is allocated evenly to each director.

The operating conditions for this example area as follows:

• The system will monitor the amount of data on each director every day.
• When each day's jobs finish, the system will determine which director has the least data, and change the insertion destination for data from APIs to that director.
• There are three directors.

The data insertion destination director can be changed during operations.

[Figure : Example of Operation Pattern for Distributing Data Evenly to Each Director]

The procedure for changing the data insertion destination director for this operation pattern is as follows:

[Figure : Procedure for Changing the Data Insertion Destination Director]

1. Execute the shundstate command, check the total number of records for each director, and record the result.

   shundstate -s director identifier -w

2. Specify the director to be used as the data insertion destination.
3. Change the value of the InsertPoint parameter in the conductor environment file to the director identifier of the director specified in Step 2 above.
4. Execute the shunsyscfgedit command to change the data insertion destination director to the value of the InsertPoint parameter specified in Step 3 above.

   shunsyscfgedit -n Shunsaku system name

Refer to 6.2.3 Monitoring Director Operation Information for more information on the content displayed by the shundstate command.

If Shunsaku File is used, users will be able to specify the range for searching and updating data. Refer to Chapter 7 Shunsaku File for more information on Shunsaku File.
