Starting the CIM Extension Manually

The management server can only obtain information from this host when the CIM extension is running. To start the CIM extension, enter the following in the /opt/APPQcime/tools directory:

# ./start

Keep in mind the following:

•You must have root privileges to run the CIM extension. The CIM extension only provides the information within the privileges of the user account that started the CIM extension. Only root

has enough privileges to provide the information the management server needs. If you do not start the CIM extension with root privileges, the management server will display messages resembling the following: Data is late or an error occurred.

•To configure UNIX CIM extensions to run behind a firewall, see ”Configuring UNIX CIM Extensions to Run Behind Firewalls” on page 389.

•If you see the message “Fork Function Failed” when you start the CIM extension, the AIX host is running low on physical or virtual memory. See ”“Fork Function Failed” Message on AIX Hosts” on page 416.

When you enter the start command, the following message is displayed:

Starting CIM Extension for AIX...

How to Determine if the CIM Extension Is Running

You can determine if the CIM extension is running by entering the following command at the command prompt:

# ./status

The CIM extension is running when the following message is displayed:

CIM Extension Running: Process ID: 93

where 93 is the process ID running the CIM extension

Configuring CIM Extensions

Configuration information is stored in a configuration text file that is read by the CIM extension on start-up. The file is named cim.extension.parameters and is located in the [Installation_Directory]/conf directory on the host. This directory also contains a file named cim.extension.parameters-sample. This file contains samples of available parameters and can be copied into the cim.extension.parameters file and used as a template.

Changing the Port Number

The CIM extension uses port 4673 by default. If this port is already in use, follow these steps to change the port the CIM extension will access:
