[Bug 214311] New: Package "sapinit" sets shared memory too low
https://bugzilla.novell.com/show_bug.cgi?id=214311 Summary: Package "sapinit" sets shared memory too low Product: SUSE Linux 10.1 Version: Final Platform: x86-64 OS/Version: SLES 10 Status: NEW Severity: Normal Priority: P5 - None Component: Commercial AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: Ulrich.Windl@rz.uni-regensburg.de QAContact: qa@suse.de The /etc/sysctl.conf.sap file (of package "sapinit") includes a shared memory setting kernel.shmall of about 5GB. As about 90% of SAP R/3's memory is located within shared memory segments, this setting prevents to use 8 GB or larger shared memory configurations. dev_disp of SAP says: Warning: tmpfs at /dev/shm is configured quite small with 3584 MB! Minimum value is 8192 MB. Recommended size is 75 % of RAM + swap -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

I don't know how these correlate, but the application server complains during startup for an 8GB RAM configuration. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

If SAP complains about /dev/shm it's a known bug and should be fixed with an upcoming update. At the latest this should happen when SAP and SLES10 is validated finally. You might want to test the packages on ftp://ftp.suse.com/pub/people/stark/misc/test/ But please be careful since they are not fully QAd. And the final update package could be different but those should also fix the problem. (Only after a reboot since it has to mount /dev/shm differently.) Dirk or Dennis, please take over this bug or dupe it on your desire. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

Ulrich, is this still an issue or already fixed for your environment?
