Issue/Introduction

Problem :

After an upgrade to a new z/OS I first received an error due to a back level Java version when I tried to deploy a product from CSM to this LPAR.
After changing the CCISPNSV PROC on this LPAR to use Java version 7.1 (31 bit) and despite coding a REGION=0M on the CSM CCISPNSV EXEC card, execution failed with the following error messages :

Environment :

z/OS release : any
CSM 5.1, 6.0 and 6.1
Java any version

Cause :

The memory usage is limited by IBM's Step Initiation Exit, IEFUSI and there is not enough memory to execute the CCISPNSV step(s) successfully. 

Resolution :

Ensure that the region size allocated by IEFUSI is at least the minimum of 1Gb as required by CCISPNSV.  

Environment

Release: MSMNGR00200-5.1-Chorus Software Manager
Component:
