3.1.6 Notes about installation and setup in Windows
- Organization of this subsection
(1) Notes about environment variables
Performance Management uses the JPC_HOSTNAME environment variable. Do not set a user-specific JPC_HOSTNAME environment variable. If such an environment variable is set, Performance Management will not function correctly.
(2) Installing and setting up multiple Performance Management programs on the same host
Performance Management enables you to install PFM - Manager, PFM - Web Console, and PFM - Agent on the same host. This subsection provides notes about such an installation.
-
If you install PFM - Manager and PFM - Agent on the same host, there is no need to install PFM - Base. In this case, PFM - Agent requires PFM - Manager; therefore, install PFM - Manager first, and then install PFM - Agent.
-
PFM - Base and PFM - Manager cannot be installed on the same host. To install PFM - Manager on a host where PFM - Base and PFM - Agent are already installed, uninstall all Performance Management programs (other than PFM - Web Console), and then install PFM - Manager and PFM - Agent in this order. Similarly, to install PFM - Base on a host where PFM - Manager and PFM - Agent are already installed, uninstall all Performance Management programs (other than PFM - Web Console), and then install PFM - Base and PFM - Agent in this order.
-
If you install PFM - Agent on a host where PFM - Manager is already installed, the PFM - Manager on the local host becomes the connection-target PFM - Manager. In such a case, you can no longer change the connection-target PFM - Manager to a PFM - Manager on a remote host. Therefore, if you want to connect to a PFM - Manager on a remote host, make sure that PFM - Manager has not been installed already on the target host.
-
If a PFM - Agent already exists on the host where PFM - Manager is being installed, the local host is redesignated as the connection-target PFM - Manager for that PFM - Agent. The resulting settings are output to the common message log file; check the results.
-
If PFM - Web Console already exists on a host where PFM - Agent is to be installed, close all browser windows before starting installation.
-
When a new Performance Management program is installed, the default is that the status management function is enabled. However, if you upgrade from version 07-00 to 08-00 or later, the settings for the status management function disabled. To change the status management function settings, see the chapter that describes Performance Management failure detection in the JP1/Performance Management User's Guide.
- Tip
-
To improve system performance and reliability, we recommend that you run PFM - Manager, PFM - Web Console, and PFM - Agent on separate hosts.
(3) Upgrading
For notes about upgrading the Performance Management programs, see the notes on version upgrades in the chapter on installation and setup in the JP1/Performance Management Planning and Configuration Guide.
For details about the precautions to be observed when upgrading from an older version of PFM - Agent, see Appendix H. Migration Steps and Notes on Migration. For details about how to upgrade PFM - Agent, see the relevant appendix in the JP1/Performance Management Planning and Configuration Guide.
(4) Notes about an SAP system employing an ASCS instance configuration
To monitor the SAP system, you need to set up an instance environment for each host that contains a central instance with dialog service (primary application server instance) or a dialog instance (additional application server instance).
(5) Notes on using the remote monitoring function
-
To use remote monitoring, you have to synchronize the system clocks of different hosts by using NTP or different means.
-
If the time zone varies between the host on which PFM - Agent is running and the one on which the monitored SAP system is running, adopt the time zone set for the SAP system by following the steps described in 3.1.5 (10) Setting up a time zone for the SAP system.
(6) Restrictions on using remote desktop connections for management
When installation or setup operation is performed by using remote desktop connections for management, the following restrictions apply:
-
Remote desktop connections can be used only for the installation, setup, uninstallation, and maintenance purposes.
-
When the above operation is performed, you must use a session 0 connection instead of regular remote desktop connection. To use session 0, specify the /console option as follows when you start a remote desktop connection application on the applicable operation terminal (client):
mstsc.exe /console
Note: mstsc.exe is an executable file that opens a remote desktop connection. Note that only one user with Administrator permissions can use session 0 connections at a time.
(7) Other notes
-
If connection dialogue instance of the SAP system does not have an MTE name for the acquisition, no performance data will be collected from the field of some records because this field does not exist in the connection-target dialog instance. As a result, a warning message (KAVF14173-W) is output to the common message log and Windows event log. This warning message is output regardless of the settings for Log (whether or not the collected performance data is to be recorded in the Store database) in each record.
-
If you attempt to install PFM - Agent for Enterprise Applications while Performance Management programs and services are running or while other programs that reference Performance Management files (such as Windows Event Viewer) are running, a message prompting for a system restart might be displayed. If this occurs, restart the system according to the message and complete the installation.
-
If you attempt to install PFM - Agent for Enterprise Applications while Performance Management programs and services are running or while other programs that reference Performance Management files (such as Windows Event Viewer) are running, file expansion might fail if there is not enough disk space or if you do not have directory permission. In such a case, terminate all such programs and then re-install PFM - Agent for Enterprise Applications. If there is not enough disk space or you do not have directory permission, resolve the problem and then re-install PFM - Agent for Enterprise Applications.
-
Before you install Performance Management programs, check to see if any security-related programs, such as those described below, are installed. If such a program is installed, take appropriate action according to the information provided below.
-
Security monitoring program
Terminate the security monitoring program or change its settings so that installation of the Performance Management programs will not be affected.
-
Virus detection program
We recommend that you terminate any virus detection program before you install the Performance Management programs.
If a virus detection program is running during installation of a Performance Management program, it might slow down the installation process, the installation might fail, or the program might not install correctly.
-
Process monitoring program
Terminate the process monitoring program or change its settings so that it does not monitor the services and processes of Performance Management or the services and processes of common components.
Installation of a Performance Management program might fail if any of these services or processes is started or stopped by the process monitoring program during the installation process.

When this product is first installed and the Programs and Features dialog box is opened, the icon displayed for the product may change immediately from the originally displayed icon. This problem relates only to the icon, and does not affect product operation.
-
This product does not support communications using IPv6 addresses. If you want to use this product in an operating system that supports IPv4/IPv6 dual stacking, the IP address that is calculated from the SAP host name on the connection destination must be resolvable by using IPv4. In this case, you must not set the environment variable SAP_IPv6_ACTIVE (which is used for IPv6 communications with the SAP system) in the execution environment for this product.
