ORA-00845: MEMORY_TARGET not supported on this systemThis is probably due to the fact that your SLES isn't configured to support shared memory, at least not in the way Oracle Database needs it.

The first one should verify that you have enough shared memory in your kernel parameters to serve your memory_target parameter. (Which value did you enter for that parameter, anyway?) You can also verify if the semaphore parameters ( sem ) have been setup as required.
sysctl -p |grep kernel df -k /dev/shm
I suppose SLES 10 SP2 is supported system for oracle 11gIt is, but this doesn't mean that the installer checks every setting for every parameter needed. Some things, e.g. configuring your kernel parameters, are [url http://docs.oracle.com/cd/E17781_01/install.112/e18802/toc.htm#BABJFAIA]part of the Installation Guide
The problem has been solved, it is quite simple ..Great to hear you've got it working now!
