B.2 Migration Procedures when Performing Failover Operations using the Standby Feature

This section describes the migration procedure for migration from an older version/level for failover operations using the standby feature.

Perform the migration procedure as described in the following table:

Step	Task
Step	Active node	Standby node
1	Install PRIMECLUSTER. (*1)	Install PRIMECLUSTER. (*1)
2	Stop the standby cluster application. (*2)
3	Stop RMS. (*3)
4	Start the GDS volume.
5	Mount the file system.
6	Modify the configuration of the standby cluster application.
7	Delete the resource information for the Symfoware database cluster.
8	Upgrade Symfoware Server.	Upgrade Symfoware Server.
9	Register the resource information for the Symfoware database cluster.
10	Modify the configuration of the standby cluster application.
11	Unmount the file system.
12	Stop the GDS volume.
13	Start RMS.
14	Start the standby cluster application.
15	Check the behavior.

*1: If a supported version of PRIMECLUSTER is not been installed
*2: If the standby cluster application is running
*3: If RMS is running.

The details for each step are described below.

1. Install PRIMECLUSTER.

On all nodes on that comprise the cluster system, check the current version of PRIMECLUSTER. If the required version is not installed, then install it.

See

Refer to "2.2 Related Software" for information on the PRIMECLUSTER versions.
Refer to the PRIMECLUSTER Installation Guide for information on installing PRIMECLUSTER.

2. Stop the standby cluster application.: Check the standby cluster application status. If it is running, stop it.

3. Stop RMS.: Check the RMS status on all nodes that comprise the cluster system. If RMS is running, stop it.

4. Start the GDS volume.: Start the GDS volume on the active node.

5. Mount the file system.: Mount the file system where the data storage destination directory was stored on the active node.

6. Modify the configuration of the standby cluster application.: Delete the database cluster resources from the standby cluster application.

7. Delete the resource information for the Symfoware database cluster.fs: Use the pgx_pclrsc command to delete the database cluster resource information on the active node.

8. Upgrade Symfoware Server.: Refer to "Chapter 3 Installation", and then upgrade Symfoware Server on all nodes that comprise the cluster system.

9. Register the resource information for the Symfoware database cluster.: Use the pgx_pclrsc command to register the database cluster resource information that was deleted in step 7 on the active node.

10. Modify the configuration of the standby cluster application.: Register the database cluster resources in the standby cluster application.

11. Unmount the file system.: Unmount the file system where the data storage destination directory was stored on the active node.

12. Stop the GDS volume.: Stop the GDS volume on the active node.

13. Start RMS.: Start RMS on all nodes that comprise the cluster system.

14. Start the standby cluster application.: Start the standby cluster application.

15. Check the behavior.: Execute switch or rebuild to check if the migration was successful.
