This article addresses some error messages caused by a Java update.
Problem:
We are receiving the following error repeatedly in the Enterprise Server console.log:
CASMG9999E CS5006,06 casgate: Init failure ( -1) in dfhgreqm with region
CASCS5006I 07 casgate: Reason was: Unable to map memory at 0805306368 for length 0002048000 07:44:05
The error occurs only when Enterprise Server is started from the command line. When started via the Enterprise Server Administration console, no error appears. Why is this happening?
Resolution:
This error message is related to a Java update from Java 1.4 to 1.5 that caused an initialization file (called cybAgent) for CA Workload Automation to be changed. Removing the following two statements from this initialization file will correct the memory error:
export IBM_JAVA_MMAP_JAVA_HEAP=true
export LDR_CNTRL=MAXDATA=0x80000000
