This subsection describes the estimation of resources used for each OS when the Web server and J2EE server are deployed on different machines. When deploying the Web server and J2EE server on different machines, estimate the resources used respectively for the Web server machine and the Application Server machine.
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.
This section describes the estimation of resources used by the Web server machine and the Application Server machine in AIX.
The following table describes the estimation of resources used by the Web server machine:
