Hi,
Here is the error message i get:
with Database Buffers = db_block_buffers * db_block_size Database Buffers = 16000 * 8192 = 125 MB
SVRMGR> startup ORA-27123: unable to attach to shared memory segment Linux Error: 22: Invalid argument ^^^^^^^^^^^
And it works with:
Database Buffers = db_block_buffers * db_block_size Database Buffers = 8000 * 8192 = 62.5 MB
SVRMGR> startup ORACLE instance started. Total System Global Area 171752720 bytes Fixed Size 48400 bytes Variable Size 105832448 bytes Database Buffers 65536000 bytes Redo Buffers 335872 bytes Database mounted. Database opened. SVRMGR>
I have enough shared memory (512MB) and free shows this:
[root@kredel7 background]# free -m total used free shared buffers cached Mem: 1012 453 558 46 354 35 -/+ buffers/cache: 63 948 Swap: 2129 0 2129
I put the strace output file at http://linux.uni-mannheim.de/strace.out
Hope that would help finding the problem.
