Preparing the connection to the CIM server

The Provisioning Manager and the CPMC communicate with a CIM server . The CPMC uses a CIM connection to communicate with the Provisioning Manager. To obtain information about an observed system, the Provisioning Manager retrieves performance information via the CIM server on that system. To prepare the communication, you can establish connections to the server by using either the HTTP protocol or the HTTPS protocol, if the CIM server is configured to support the chosen protocol. For more information about configuring the CIM server, see the z/OS Common Information Model User’s Guide. For the HTTPS protocol, you use an AT-TLS configuration. The Provisioning Manager and the CPMC do not support authentication based on SSL certificates.

Note:

Ensure that the configured port of the CIM server matches the definitions that you make in your domain configuration and in the connections defined using the CPMC.

Required settings for the RMF™ Distributed Data Server

If you are using RMF to provide performance information on the observed system, then you should configure the GPMSRVxx member that is used by the RMF Distributed Data Server. This member must specify a higher value for MAXSESSIONS_HTTP than the default of 20. The recommended value is 60 or higher.

MAXSESSIONS_HTTP(60) /* MaxNo of concurrent HTTP requests */
