This subsection describes the prerequisites for installation and setup, and provides cautionary notes and other information you should know before installing and setting up PFM - RM for Oracle in a cluster system.
The following are the prerequisites for running PFM - RM for Oracle in a cluster system.
Make sure that the following conditions are satisfied:
Make sure that the following conditions are satisfied:
Make sure that the following conditions are satisfied:
Performance Management supports IPv6 environments as well as IPv4 environments as a network configuration. Therefore, Performance Management can operate even in a network configuration in which both an IPv4 environment and an IPv6 environment are used.
PFM - RM for Oracle can communicate with PFM - Manager via IPv6. Note that this explanation applies only when the OS of a host on which PFM - RM for Oracle and PFM - Manager are installed is Windows Server 2008 R2 or Linux.
For details about the scope of communication in an environment with both IPv4 and IPv6, see M. About Communication in IPv4 Environments and IPv6 Environments.
When you want to use IPv6 for communication between PFM - Manager and PFM - RM for Oracle, the settings for using IPv6 must be enabled for both the PFM - Manager host and the PFM - RM host. You can specify the settings by executing the jpcconf ipv6 enable command. The following explains when the command needs to be executed and when it does not need to be executed.
The following shows an example of executing the jpcconf ipv6 enable command:
jpcconf ipv6 enable
Execute the jpcconf ipv6 enable command separately on the executing node and on the standby node.
For details about the jpcconf ipv6 enable command, see the chapter that describes commands in the manual Job Management Partner 1/Performance Management Reference. For details about the conditions or occasions for executing the jpcconf ipv6 enable command, see the chapter that describes network configuration examples in an environment that includes IPv6 in the Job Management Partner 1/Performance Management Planning and Configuration Guide.
When you use IPv6 for communication between a monitored host and PFM - RM for Oracle, specify the name of a monitored host where name resolution can be performed.
Communication between PFM - RM for Oracle and a monitoring target is performed with an IP address that can be resolved. Also, if an IPv4 environment and an IPv6 environment are both used, and communication between PFM - RM for Oracle and the monitoring target fails with an IP address that can be resolved, the communication is not retried by using another IP address.
For example, if communication fails when IPv4 is used, IPv6 is not used to retry communication. Similarly, if communication fails when IPv6 is used, IPv4 is not used to retry communication. Make sure beforehand that a connection can be established.
When you set up PFM - RM for Oracle to run in a logical host environment, you must specify the information shown in the following table, in addition to the environment information required for PFM - RM for Oracle setup.
Table 3-4 Information required to set up PFM - RM for Oracle to run on a logical host
Item | Example |
---|---|
logical host name | jp1-halora |
logical IP address | 172.16.92.100 |
Shared disk | /jp1 |
When multiple Performance Management programs are installed on a single logical host, the programs share the same directory on the shared disk.
For details about how much shared disk capacity is needed, see A. Estimating System Requirements.
In a system configuration in which PFM - RM for Oracle runs on a logical host, consider whether you want the entire logical host to fail over when an error occurs in PFM - RM for Oracle.
If the entire logical host is failed over when an error occurs in PFM - RM for Oracle, business applications on the logical host will also be failed over. Failover of these applications may affect any business operations that are in progress.
