Patch level detected:Dollar Universe 5.6
On Dollar Universe 5 in AIX, SAP jobs are failing with the above error messages.

Cause

Cause type:
Configuration
Root Cause: This issue is due to the file descriptor limits of the SAP manager process owner and the available memory of the SAP manager process.

Environment

OS: IBM AIX
OS Version: N/A
Related configuration item(s): Manager SAP 4.4.1

Resolution

To fix this issue:

1. Stop the SAP Manager (in case it is still running)
2. Using the 'ulimit' command, set the value to 'unlimited' for the 'data':

ulimit -d unlimited

3. Double check that this change has been taken in account with the command:

ulimit -a

The concerned user is the owner of the SAP manager process.

4. Edit the file 'uxstartjcs.ksh' and add the following environment variable, for example:

export LDR_CNTRL=MAXDATA=0x40000000
nohup $UXEXE/uxagtsap ${AREA} ${UCOMPANY} ${UNODE} > $UXSAP/log/univmgr_${UCOMPANY}_${UNODE}_${AREA}.log 2>&1 &
unset LDR_CNTRL

Remark : the value 0x40000000 corresponds to a data segment of 1G.

5. Restart the SAP Manager in using the command 'uxstartjcs.ksh'.
