INIT JAVA HEAP SIZE field
Indicates the size in megabytes of the initial Java heap (the middleware heap within non-system heap) for the JVM used by the DSNWLM_JAVA WLM environment. This value is assigned to the -Xms option in the JVM startup options file specified in the JVM PROPERTIES FILE field.
| Acceptable values: | DEFAULT or 1–99999 (in megabytes) |
|---|---|
| Default: | 32 |
| Update: | None |
| Data sharing scope: | Group |
| DSNZPxxx: | None |
| z/OSMF variable: | JVMHEAP |
If you specify DEFAULT, the -Xms option is assigned 64M, but remains commented out in the JVM startup options file. If you specify a numeric value, it is assigned to the -Xms option and the option is active 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.
