Issue/Introduction

Encountering a PIEHP0002 error when the environment has some storage limitations. 
This can be related to the job class definition or a problem with LE options or HEAP options which are being used. 

What can specifically be done to resolve this?

Environment

Easytrieve Report Generator, release 11.6

Resolution

The recommendation is to run with the following values for your //CEEOPTS DD statement for the LE options:

//CEEOPTS DD *
RPTOPTS(ON)
RPTSTG(ON)
ALL31(ON), STACK(,,ANYWHERE,KEEP,,), HEAP(,,,FREE,,)
/*

Here are the HEAP options for your reference which we have in effect, and we are not getting the PIEHP0002 error:

PARMLIB(CEEPRMS0) ANYHEAP(16384,8192,ANYWHERE,FREE)
PARMLIB(CEEPRMS0) BELOWHEAP(8192,4096,FREE)
DD:CEEOPTS HEAP(32768,32768,ANYWHERE,FREE,8192,4096)
PARMLIB(CEEPRMS0) HEAPCHK(OFF,1,0,0,0,1024,0,1024,0)
PARMLIB(CEEPRMS0) HEAPPOOLS(OFF,8,10,32,10,128,10,256,10,1024,10,2048,10,0,10,0,10,0,10,0,10,0,10,0,10)
IBM-supplied default HEAPZONES(0,ABEND,0,ABEND)
PARMLIB(CEEPRMS0) THREADHEAP(4096,4096,ANYWHERE,KEEP)

Please check if you are using a default for the HEAP() option .. which is HEAP(,,,KEEP,,).
This means that even if you call the free routine to release memory, it isn’t actually freed.
There are a variety of bugs that occur if the memory is really freed. So IBM recommends using the KEEP option to avoid these.
