Figure 26-2 shows a system configuration for applying the facility for monitoring MIB performance information to a HiRDB/Single Server.

Figure 26-2 System configuration for a HiRDB/Single Server

Explanation

JP1/ESA is installed in the server machine where the monitored HiRDB is located.

Figure 26-3 shows a system configuration for applying the facility for monitoring MIB performance information to a HiRDB/Parallel Server.

Figure 26-3 System configuration for a HiRDB/Parallel Server

Explanation

JP1/ESA is installed in the server machine where the system manager is defined, because that is the server machine where performance information is collected; there is no need to install JP1/ESA in other server machines.

MIB commands are executed at the server machine where the system manager is defined.

Figure 26-4 shows a system configuration for applying the facility for monitoring MIB performance information to a multi-HiRDB configuration of HiRDB/Single Servers.

Figure 26-4 System configuration for a multi-HiRDB configuration of HiRDB/Single Servers

Explanation

In the case of a multi-HiRDB configuration, a single MIB command can be used to monitor multiple HiRDBs. You must specify in the MIB environment definition file all the HiRDBs that are to be monitored. Note that there is no requirement that you monitor all the HiRDBs; it is possible to monitor only selected HiRDBs.

Figure 26-5 shows a system configuration for applying the facility for monitoring MIB performance information to a 1-to-1 switchover configuration.

Figure 26-5 System configuration for a 1-to-1 switchover configuration

Explanation

If you are using a system switchover facility, you must also set up the server machine in the standby system for performance monitoring. That way, if system switchover should occur, monitoring will be continued for the server machine at the switching destination. However, as is shown in Figure 26-6, the collected performance information is not continuous. After switchover, it will appear as though a different HiRDB were being monitored.
