5.1.4 Resources used by Management Server

This subsection describes the estimation of resources used by Management Server for each OS.

Note that the Example of option settings in each table of estimation of resources used differs according to the OS and the kernel versions in use. Reference the manual of the OS being used and set up the estimates based on the estimation formula in the table. The settings are not required when the corresponding kernel parameter is not applicable in the OS being used.

Organization of this subsection

(1) In AIX

The following table describes the estimation of resources used by Management Server:

Table 5‒9: Estimation of resources used by Management Server (In AIX)

A represents the number of Management actions executed concurrently. Add the following value only if Management actions are executed when a Management event occurs:

  • The total of the values specified for the manager.mevent.send.max keys in the property file for issuing Management events for each J2EE server.

(2) In Linux

A represents the number of Management actions executed concurrently. Add the following value only if Management actions are executed when a Management event occurs:

  • The total of the values specified for the manager.mevent.send.max keys in the property file for issuing Management events for each J2EE server.
