4.2.2 Network environment setup

(1) IP address setup

You must set up at the PFM - Agent host an environment in which IP address can be resolved from host names. PFM - Agent cannot start in an environment in which IP addresses cannot be resolved.

Actual host names or alias names can be used for a monitoring host name (the name used as the host name of a Performance Management system).

• When using an actual host name as a monitoring host name

  Execute the hostname command on a Windows system or uname -n command on a UNIX system to check the host name, and set up the environment so that it can resolve IP addresses. Note that on a UNIX system, the host name obtained by the hostname command can also be used.

• When using an alias name as a monitoring host name

  Set up the environment so that it can resolve the IP addresses for the set alias name.

For details about monitoring host name settings, see the chapter explaining installation and setup in the JP1/Performance Management Planning and Configuration Guide.

Use one of the following methods to set up the host name and IP address:

• The host information settings file for Performance Management (jpchosts file)

• hosts file

• DNS

Important

• Performance Management can be run on a DNS environment, but does not support host names in the FQDN format. Accordingly, leave out the domain name when setting monitoring host names.

• If PFM - Agent for Platform is to be used in multiple LAN environments, set up the IP address in the jpchosts file. For details, see the chapter explaining installation and setup in the JP1/Performance Management Planning and Configuration Guide.

• Performance Management cannot be run on a host on which DHCP is used to assign dynamic IP addresses. Set fixed IP addresses on all hosts on which Performance Management is installed.

Performance Management supports IPv6 network configurations in addition to IPv4 environments. Performance Management also works in network configurations that are made up of a mix of IPv4 and IPv6 environments.

PFM - Agent for Platform can communicate with PFM - Manager over IPv6, but only if both are hosted on Windows or Linux.

For details about and limitations applicable to communication in the IPv4 and IPv6 environments, see L. Communication in IPv4 and IPv6 Environments.

To communicate over IPv6, you must enable IPv6 on the PFM - Manager host, as well as on each PFM - Agent host. Before installing PFM - Agent for Platform, you must also enable the use of IPv6 on the PFM - Agent host. To configure this setting, execute the jpcconf ipv6 enable command. If the use of IPv6 is already enabled, there is no need to configure this setting. To check whether the use of IPv6 is enabled, execute the jpcconf ipv6 display command.

For details about the jpcconf ipv6 enable and jpcconf ipv6 display commands, see the chapter that describes commands in the manual JP1/Performance Management Reference. For details about the timing and conditions for executing the jpcconf ipv6 enable command, see the chapter that describes network configurations that include IPv6 environments in the JP1/Performance Management Planning and Configuration Guide.

Also note that if you want PFM - Agent for Platform to communicate with PFM - Manager over IPv6, you must specify host names that can be resolved.

Communication between PFM - Agent for Platform and PFM - Manager is established using resolvable IP addresses. When PFM - Agent for Platform and PFM - Manager communicate in an environment in which IPv4 and IPv6 coexist and an attempt to communicate with one resolvable IP address fails, no attempt will be made to communicate using the other IP address.

For example, when an IPv4 connection fails, a retry over IPv6 will not be attempted. Similarly, when an IPv6 connection fails, a retry over IPv4 will not be attempted. We recommend to confirm connections in advance, if possible.

(2) Port number setup

The default port numbers shown in the table below are assigned to Performance Management program services. For any other services or programs, port numbers currently not in use in the system are automatically assigned when the service or program is started. When you are using Performance Management in an environment with a firewall, assign fixed port numbers. For details about how to fix port numbers, see the chapter explaining installation and setup in the JP1/Performance Management Planning and Configuration Guide.

Table 4‒1: Default port numbers and Performance Management program services (for UNIX)

Service explanation	Service name	Parameter	Port number	Remarks
Service configuration information management function	Name Server	jp1pcnsvr	22285	Port number used by the Name Server service of PFM - Manager. This port number is set for all hosts in Performance Management.
Service status management function	Status Server	jp1pcstatsvr	22350	Port number used by the Status Server service of PFM - Manager and PFM - Base. This port number is set for hosts in which PFM - Manager and PFM - Base are installed.
JP1/SLM linkage facility	JP1/ITSLM	--	20905	Port number set in JP1/SLM.

Set up the network to enable these PFM - Agents to communicate using the assigned port numbers.
