I suggest two things:

1) validate that the user setting for root, <sid>adm & ora<adm> match the requirements on pg 34 of the NW04 ABAP IPG

2) ensure you have at LEAST 1.5GB in the temporary directory to be used by sapinst

This problem is nearly always to do with User Limits. Depending on the shell you are using you can view and change the limits using the limit or the ulimit command. If you change a limit the new value holds only for the shell and processes started in this shell. Hence if you change limits you have to do it in identically the same shell process from which you start sapinst.

If you are using csh or tcsh run limit to view all limits. The limits stacksize, datasize and memory are especially important. If they are not yet unlimited you should set them to unlimited using the commands

limit stacksize unlimited

limit datasize unlimited

limit memory unlimited

Please verify the result using


If you are using ksh or bash run

ulimit -a

to view the limits and

ulimit -d unlimited

ulimit -s unlimited

ulimit -m unlimited

to set the limits.

Retry the SAPinst once you have set these ulimits

As soon as we increased the space, the GUI ran just fine.

Please refer below discussion,

This will help to resolve the problem
