Issue/Introduction

While executing an Endevor generate processor containing a precompiler step that utilizes Unix System Services, the step abends with a java heap error. 

JVMDUMP055I Processing dump event "systhrow", detail "java/lang/OutOfMemoryError", exception "Java heap space"
JVMDUMP013I Processed dump event "systhrow", detail "java/lang/OutOfMemoryError".
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

The job executes successfully outside of Endevor.

Resolution

The ASSIZEMAX parameter for Endevor Alternate ID was added to the OMVS segment definition. This overrides the MAXASSIZE parameter specified in SYS1.PARMLIB member BPXPRMxx.  This drives the maximum size of an address space created by Unix (region above the line plus region below the line).
