17.4 Migrating Managers

If a Manager with an existing operating environment is migrated to another Manager for some reason, there are two types of migration, as follows:

• Inheriting only the configuration information for the source Manager
  In this case, a new PDB will be created, but configuration information for Agents in the previous environment will be inherited.
• Inhering the PDB from the source Manager as well
  In this case, the PDB will be migrated from the source Manager to the destination Manager, and both the performance information that has been collected from Agents and configuration information for Agents will be inherited.

The following sections explain how to migrate Managers in each of these cases.

17.4.1 Inheriting only the configuration information for the source Manager 

Perform the following procedure:

1. Extract configuration information from the PDB of the source Manager
   Output configuration information from the source Manager to a file as described in Section 18.4, "sqcPDBexport (Configuration Information Export Command)". Note that the host name of the destination Manager must be specified in the -n option.
2. Install the destination Manager
   Install the destination Manager from scratch as described in Section 4.1.1, "Tasks required for Manager installation".
3. Import the configuration information into the destination Manager
   Place the configuration information file that was output in step 1 in the following folder on the destination Manager.

   

   Variable file directory\transfer\DsaPDBWriter

   
   

   

   /var/opt/FJSVssqc/temp/DsaPDBWriter

   It will take approximately 60 seconds to store the configuration information in the PDB. After the information has been stored, the ".tmp" file will be deleted.

4. Make any changes to the IP address of the Manager
   If the IP address of the Manager has changed, change the IP address settings at this point.
   Perform this task by referring to Section 17.3, "Changing the IP Address of a Manager".

17.4.2 Inhering the PDB from the source Manager as well

Perform the following procedure:

1. Back up the PDB on the source Manager
   Back up the PDB file on the source Manager as described in Section 17.2.1.1, "PDB files".
2. Extract configuration information from the source PDB
   Output the configuration information from the source PDB to a file as described in Section 18.4, "sqcPDBexport (Configuration Information Export Command)". Note that the host name of the destination Manager must be specified in the -n option.
3. Install the destination Manager
   Install the destination Manager from scratch as described in Section 4.1.1, "Tasks required for Manager installation". However, do not start resident processes as explained in Section 4.1.1.2, "How to start and verify the program".
4. Copy the PDB from the source Manager to the destination Manager
   Copy the source PDB that was backed up in step 1 to the same path on the destination Manager.
5. Copy the configuration information from the source Manager to destination Manager.
   Place the configuration information file that was output by step 2 in the following folder on the destination Manager.

   

   Variable file directory\transfer\DsaPDBWriter

   

   /var/opt/FJSVssqc/temp/DsaPDBWriter

6. Start the resident processes on the destination Manager
   Start the resident processes as described in Chapter 5, "How to Start and Stop Resident Processes". Also, make sure that the resident processes are running correctly.
7. Make any changes to the IP address of the Manager
   If the IP address of the Manager has changed, change the IP address settings at this point.
   Perform this task by referring to Section 17.3, "Changing the IP Address of a Manager".
