(6) Notes on using JP1 authentication mode

(1) Notes on failover occurrence detection

It is difficult for Performance Management to detect failovers on PFM - Manager, PFM - Agent, or PFM - RM nodes. To detect the occurrence of a failover, you need to utilize methods such as using cluster software management tools, SNMP traps issued by the cluster software, or message monitoring of log files. For details on message monitoring of log files, see 13.5 Detecting problems by linking with the integrated system monitoring product.

(2) Notes on starting and stopping Performance Management

Use the cluster software to start and stop Performance Management that is used on a logical host registered in the cluster software. If you start up or stop Performance Management using a method other than the operating cluster software, such as by using the jpcspm start or jpcspm stop command, there might be a difference between the actual Performance Management status and the status controlled by the cluster software, causing an error to be assessed.

(3) Notes on setting Status Server services

One host can run only one Status Server service. For that reason, the Status Server service on a physical host manages the status of the physical host and logical host services. You need to set the Status Server service not to perform a failover or run constantly.

(4) Notes on command execution

Only the executing node can execute the following PFM - Web Console commands when Performance Management is used on a logical host:

jpcaspsv command

jpcasrec command

jpcmkkey command

jpcrdef command

jpcrpt command

Both the executing node and standby node can execute the jpcwras and jpcwagtsetup commands. These two commands act for the physical host that executes the commands.

(5) Notes on networks

Performance Management on a physical host cannot operate if it cannot communicate using the physical IP address that corresponds to the physical host name (in the Windows system, the host name displayed when the hostname command is executed, and in the UNIX system, the host name displayed when the uname -n command is executed).

(6) Notes on using JP1 authentication mode

To use JP1 authentication mode in an environment using PFM - Manager on a cluster system, JP1/Base must also be used on the cluster system. The JP1/Base version must be 08-00 or later.
