oracle 11g install prerequisite fails for valid rhel 4 kernel parameter value
Okay I have never had this happen before. Installing Oracle 11gR2 client
on RHEL 4 x86 and prereq for semmni fails to recognize Linux value.
Initially there were six other kernel parameters that failed and I reset
them in the /etc/sysctl.conf file, ran sysctl -p, and no problem passing
on the second try except for semmni. The value is:
>/sbin/sysctl -a | grep sem
kernel.sem = 250 32000 100 128
> cat /proc/sys/kernel/sem
250 32000 100 128
> uname -a
Linux semele 2.6.9-67.0.20.ELsmp #1 SMP Wed Jun 18 12:40:47
EDT 2008 i686 i686 i386 GNU/Linux
> cat /etc/issue
Red Hat Enterprise Linux AS release 4 (Nahant Update 8)
Oracle installer says expected value is 128 and actual value 0. I have
successfully installed the client on another Linux server with the
same basic install with no problems. Oracle support suggests a reboot.
Is there any reason Linux shows the parameter but Oracle cannot see it?
Oracle sees the other 3 parameters: SEMMSL, SEMMNS, SEMOPM
Is this value stored anywhere else on Linux? Do you agree that a reboot
might fix this?
Thanks for reply. I agree that we do not want to ignore prereqs as this is our production application server running Client 10gR2. We are installing Client 11gR2 in conjunction with database upgrade in Feb 2011. If reboot solves the issue, then happy days are here again! However, if it does not, and all other pre-reqs pass, if I ignore just the semmni parameter and then install Oracle, I wonder what the risk is for later issues.
