MAX APPL HEAP SIZE field
Indicates the maximum size in megabytes of memory for application work (non-system heap) in the JVM used by the DSNWLM_JAVA WLM environment. This value is assigned to the -Xmx option in the JVM startup options file specified in the JVM PROPERTIES FILE field.
| Acceptable values:: | DEFAULT or 1–99999 (in megabytes) |
|---|---|
| Default: | DEFAULT |
| Update: | None |
| Data sharing scope: | Group |
| DSNZPxxx: | None |
| z/OSMF variable: | JVMAPPH |
If you specify DEFAULT, the -Xmx option is assigned 128M but remains commented out in the JVM startup options file. If you specify a numeric value, it is assigned to the -Xmx option and the option is active (uncommented) in the JVM startup options file. Note that the CLIST has no way to validate whether system resources are available to support the specified size.
If you do not use Java, just accept the default setting.
