# Memory Requirements

Memory usage of a configured environment consists of the following elements:

- Workspace Manager

- Listeners

- Concurrently running application agents

Actual memory usage depends on application features, and varies depending on the application. The SHRLIBRGNSIZE parameter (defined on SYS1.PARMLIB, member BPXPRMxx) can affect the amount of memory that the server address space will allocate. For SHRLIBRGNSIZE, we recommend the default MVS installation value of 64Mb:

    SHRLIBRGNSIZE(67108864)

Server memory usage:

- The workspace (including listeners) uses 200 megabytes.

- Each pre-started agent requires 20 megabytes.

The minimum amount of memory for a newly installed server with no workload is 250Mb. However, depending on usage, workload, and configuration options, 500Mb is recommended to start, to be adjusted as needed.
