6.1.1 Resources used for deploying batch server
This subsection describes the estimation of the resources used for deploying batch servers for each OS. When deploying the batch servers, estimate the resources used by the machine on which the batch servers is deployed.
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.
Furthermore, for details about the estimation of the resources used for each process, see 6.2 Resources used for each process.
For details about the required virtual memory, see 6.3 Estimating virtual memory usage. For details about the disk occupancy, see the release notes of Application Server.
