Well, one thing I noticed is that a few of your kernel parameters are not correct. Specifically: set semsys:seminfo_shmmax=4294967295 set semsys:seminfo_shmmin=1 set semsys:seminfo_shmseg=50 set semsys:seminfo_shmmni=200 should really be: set shmsys:shminfo_shmmax=4294967295 set shmsys:shminfo_shmmin=1 set shmsys:shminfo_shmseg=50 set shmsys:shminfo_shmmni=200 That is, these are shared memory (shm*) parameters, not semaphore (sem*) parameters. ===================================== Jim Silverman Senior Systems Database Administrator Solucient, LLC Telephone: 734-669-7641 FAX: 734-930-7611 E-Mail: jsilverman@xxxxxxxxxxxxx -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Onkar N Tiwary Sent: Tuesday, November 22, 2005 8:01 AM To: oracle-l@xxxxxxxxxxxxx Subject: ORA 27102 + oracle 10g + solaris8 hi , I have got a solaris box where i was installing oracle 10g .
