The following describes the network environment required to run Performance Management.
(a) IP address settings
The PFM - RM for Oracle host must be set up in a network environment where IP addresses can be resolved from host names. PFM - RM for Oracle will not start in an environment where IP addresses cannot be resolved.
You can use the real host name as a monitoring host name (a host name used in Performance Management system).
In a Windows system, set up the environment so that an IP address can be resolved from the host name returned by the hostname command. In a UNIX system, set up the environment so that an IP address can be resolved from the host name returned by the uname -n command.
For details about the configuration of a monitoring host name, see the chapter on installation and setup in the Job Management Partner 1/Performance Management Planning and Configuration Guide.
Note that IP addresses set in the jpchosts file are not used for resolving the IP addresses of monitoring targets.
Use one of the following methods to set the host name and IP address of a host monitored by Performance Management programs:
- Host information settings file for Performance Management (jpchosts file)
- hosts file
- DNS (Domain Name System)
Use a real host name or an alias name for the monitoring host name.
- When using a real host name
In a Windows system, set up the environment so that an IP address can be resolved from the host name returned by the hostname command.
Note that although Performance Management can operate in a DNS environment, it does not support host names in FQDN (Fully Qualified Domain Name) format. Therefore, specify a monitoring host name without the domain name.
- When using an alias name
Set up the environment so that an IP address can be resolved from the specified alias name.
For details about the structure of a monitoring host name, see the chapter that describes how to change the system configuration in the Job Management Partner 1/Performance Management Planning and Configuration Guide.
- Notes on setting IP addresses:
- If you intend to use Performance Management within multiple LAN environments, set the IP addresses in the jpchosts file. For details, see the chapter on installation and setup in the Job Management Partner 1/Performance Management Planning and Configuration Guide.
- Performance Management cannot operate on the hosts to which IP addresses are assigned dynamically by DHCP. Make sure that all the hosts on which Performance Management programs are installed are configured with user-specified static IP addresses.
(b) Settings when IPv6 used
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.
- Cases when the jpcconf ipv6 enable command needs to be executed:
- When switching from an IPv4 environment to an IPv6 environment on each host
- When switching the PFM - Manager environment from IPv4 to IPv6 in an environment in which both IPv4 and IPv6 are used
- Cases when the jpcconf ipv6 enable command does not need to be executed:
- When each host already operates in an IPv6 environment
- When PFM - Manager operates in an IPv6 environment in an environment in which both IPv4 and IPv6 are used
The following shows an example of executing the jpcconf ipv6 enable command:
jpcconf ipv6 enable
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.
(c) Port number settings
The following table shows the default port numbers assigned to the services of Performance Management programs. For other services and programs, available port numbers are automatically assigned each time they are started. If you use Performance Management in a firewall environment, use fixed port numbers. For details about how to set fixed port numbers, see the chapter on installation and setup in the Job Management Partner 1/Performance Management Planning and Configuration Guide.
Table 2-1 Default port numbers for Performance Management program services (in Windows)
Service description | Service name | Parameter | Port number | Remarks |
---|
Service configuration information management facility | Name Server | jp1pcnsvr | 22285 | The port number used by the Name Server service of PFM - Manager. This port is set up on every Performance Management host. |
OpenView linkage facility | NNM Object Manager | jp1pcovsvr | 22292 | The port number used by the OpenView linkage facility of PFM - Manager and PFM - Base to provide communication between the map manager and object manager. This port is set up on the hosts on which PFM - Manager and PFM - Base are installed. |
Service status management facility | Status Server | jp1pcstatsvr | 22350 | The port number used by the Status Server service of PFM - Manager and PFM - Base. This port is set up on the hosts on which PFM - Manager and PFM - Base are installed. |
Monitoring console communication facility | View Server | jp1pcvsvr | 22286 | The port number used by the View Server service of PFM - Manager. This port is set up on the hosts on which PFM - Manager is installed. |
Web service facility | Web Service | -- | 20358 | The port number used by the Web Service service of PFM - Web Console. |
Web container facility | Web Console | -- | 20359 20360 | The port number used by the Web Console service of PFM - Web Console. |
JP1/ITSLM linkage facility | JP1/ITSLM | -- | 20905 | The port number set by JP1/ITSLM. |
- Legend:
- --: None
Ensure that the network is set up to allow communication using these port numbers, which are used by PFM - RM for Oracle.
This subsection describes the prerequisite programs required to install PFM - RM for Oracle.
The host on which PFM - RM for Oracle is installed is hereafter called "PFM - RM host".
There are roughly two cases in the program configuration of PFM - RM for Oracle. The actual program configuration needs to be determined based on the system configuration.
- Install PFM - RM for Oracle on the PFM - Manager host
- This configuration is the program configuration for installing PFM - RM for Oracle on the same host on which PFM - Manager is installed. In this program configuration, you need to install Oracle Client on the same host on which PFM - RM for Oracle is installed.
- The following figure 2-1 shows the program configuration in this case:
Figure 2-1 Program configuration (installation of PFM - RM for Oracle on the PFM - Manager host (Windows))
![[Figure]](figure/zuo02006.gif)
- Install PFM - RM for Oracle on the different host from PFM - Manager host
- This configuration is the program configuration for installing PFM - RM for Oracle on the different host from PFM - Manager host.
- In this program configuration, you need to install PFM - Base and Oracle Client on the same host on which PFM - RM for Oracle is installed. The following figure shows the program configuration in this case:
Figure 2-2 Program configuration (installation of PFM - RM for Oracle on the same host on which PFM - Base and Oracle Client are installed (Windows))
![[Figure]](figure/zuo02001.gif)
(a) Monitoring target programs
The monitoring target programs of PFM - RM for Oracle are as follows:
- Oracle Database Standard Edition
- Oracle Database Standard Edition One
- Oracle Database Enterprise Edition
Note that when a monitoring target program running on a virtualized OS is being monitored, PFM - RM for Oracle monitors what the monitoring target program can perform on the virtualized OS.
(b) Performance Management programs
Install PFM - RM for Oracle and PFM - Base on the PFM - RM host.
PFM - Base is a prerequisite program for PFM - RM for Oracle. Only one instance of PFM - Base is required, even when multiple instances of PFM - RM are installed on one host.
Note that you do not need to install PFM - Base if PFM - Manager and PFM - RM for Oracle are installed on the same host.
To monitor Oracle operation using PFM - RM for Oracle, PFM - Manager and PFM - Web Console are required.
Note the following when installing and setting up Performance Management.
(a) Precautions regarding environment variables
Because Performance Management uses JPC_HOSTNAME as an environment variable, do not set it as a user-specific environment variable, as this will prevent Performance Management from operating properly.
(b) Notes on installing and setting up multiple Performance Management programs on same host
With Performance Management, you can install PFM - Manager, PFM - Web Console, and PFM - RM for Oracle on the same host. When doing so, note the following:
- When PFM - Manager and PFM - RM for Oracle are installed on the same host, PFM - Base is not required. In this case, PFM - Manager is a prerequisite program for PFM - RM for Oracle and must be installed before PFM - RM for Oracle is installed.
- You cannot install PFM - Base and PFM - Manager on the same host. If you want to install PFM - Manager on a host on which PFM - Base and PFM - RM for Oracle are already installed, uninstall all Performance Management programs, and then install PFM - Manager and PFM - RM for Oracle in that order. The same applies when you install PFM - Base on a host on which PFM - Manager and PFM - RM for Oracle are already installed: you must uninstall all Performance Management programs, and then install PFM - Base and PFM - RM for Oracle in that order.
- If you install PFM - RM for Oracle on a host on which PFM - Manager is already installed, the connection-target PFM - Manager will be the instance of PFM - Manager on the local host, and cannot change it to that on the remote host. If you want PFM - RM for Oracle to connect to PFM - Manager on a remote host, ensure that PFM - Manager is not installed on the host on which you install PFM - RM for Oracle.
- If you install PFM - Manager on a host on which PFM - RM for Oracle is already installed, the connection-target PFM - Manager is reset to the local host. See the setting results that are output to the common message log.
- If you install PFM - RM for Oracle on a host on which PFM - Web Console in already installed, close all the browser windows before you install the program.
- When you perform a new installation of a Performance Management program, the status management facility will be enabled by default. To change the setting of the status management facility, see the chapter on error detection for Performance Management in the Job Management Partner 1/Performance Management User's Guide.
- Hint:
- To improve system performance and reliability, we recommend running PFM - Manager, PFM - Web Console, and PFM - RM for Oracle on separate hosts.
(c) Notes on upgrading PFM - RM for Oracle
Note the following when upgrading PFM - RM for Oracle.
For details about upgrading, see the Job Management Partner 1/Performance Management Planning and Configuration Guide.
- Before installing Performance Management programs, make sure that no Performance Management programs and services are running on the local host, regardless of whether they are running on a physical or a logical host. For details about how to stop services, see the chapter on starting up and stopping Performance Management in the Job Management Partner 1/Performance Management User's Guide.
- If you install PFM - RM for Oracle on a host on which Performance Management programs are already installed, PFM - RM for Oracle will be installed in the same folder as the Performance Management programs other than PFM - Web Console. To change the installation folder, you must delete the Performance Management programs except PFM - Web Console and then re-install them.
- You cannot install PFM - Base and PFM - Manager on the same host. If you want to install PFM - Manager on a host on which PFM - Base and PFM - RM for Oracle are already installed, uninstall all Performance Management programs except PFM - Web Console, and then install PFM - Manager and PFM - RM for Oracle in that order. The same applies when you install PFM - Base on a host on which PFM - Manager and PFM - RM for Oracle are already installed: you must uninstall all Performance Management programs except PFM - Web Console, and then install PFM - Base and PFM - RM for Oracle in that order.
- When you upgrade, if the data model version of the Store database will change, the current Store database is automatically updated with the result that twice the disk space for the Store database is temporarily required. Before upgrading, make sure that there is enough free space on the disk where the Store database is stored. Estimate the necessary free space based on the total size of the current Store database. For example, if the total size of the current Store database is 100 gigabytes, at least 200 gigabytes of free space will be required for installation. If you change the disk where the Store database is stored, take into consideration the amount of disk space that will be needed on the disk after the switch.
(d) Other cautionary notes
- To monitor a monitoring target program, you need to install Oracle Client 32-bit and set up the environment.
- When you perform a new installation of PFM - RM for Oracle in an environment where no other Performance Management program has been installed, make sure that there are no files or folders in the installation folder.
- You may be prompted to restart the system if you attempt to install PFM - RM for Oracle while another Performance Management program or service is running. Alternatively, you may be prompted to restart the system while Windows Event Viewer or another program that references Performance Management files is running. If this occurs, restart the system as indicated in the message, and complete the installation.
- The installer may be unable to expand the files required for installation if you attempt to install PFM - RM for Oracle in the following cases:
- While a Performance Management program or service is running or while another program that references Performance Management files (for example, Windows Event Viewer) is running
- When there is insufficient disk space
- When you do not have the required folder permission
Stop any active Performance Management programs or services or other programs that reference Performance Management files, and then perform the installation again. If the problem is caused by insufficient disk space or a lack of the appropriate folder permissions, fix the problem and then perform the installation again.
- When you install Performance Management programs, check whether the following security-related programs are installed. If they have been installed, take appropriate action according to the explanations below.
- Security monitoring program
Stop the security monitoring program or change the settings so that the installation of Performance Management programs will not be interrupted.
- Virus detection program
Stop the virus detection program before you install Performance Management programs.
If a virus detection program is running during the installation of Performance Management programs, the installation processing might slow down, installation might not be executable, or the programs might not be able to be installed correctly.
- Process monitoring program
Stop the process monitoring program or change the settings. Also, specify settings that prevent the services or processes of Performance Management and common components from being monitored.
If the process monitoring program starts or stops these services or processes during the installation of Performance Management programs, installation might fail.
