ORA-27102: https://urisnotaword.wordpress.com/2010/07/16/ora-27102-out-of-memory-linux-x86_64-error-28-no-space-left-on-device/ out of memory tips Oracle Error Tips by Stephanie F. First solution by Mircea Vutcovici I got the ORA-27102 error upon instance startup: SQL> startup ORA-27102: out of memory Linux-x86_64 Error: 28: No space left on device My OS is Red Hat Linux (RHEL 5.4 x64), and I?ve traced the out of sqlplus process and here was the error: shmget(0x37ed6a3c, 1243611136, IPC_CREAT|IPC_EXCL|SHM_HUGETLB|0600) = -1 ENOSPC (No space left on device)The solution was to increase kernel.shmall from 2097152 (as it is in the install doc for oracle 10h and oracle 11g) to 4194304. Probably is better to leave the RHEL5 default which is 4294967296The issue is documented online: ?Upon startup of Linux database get ORA-27102: out of out of memory memory Linux-X86_64 Error: 28: No space left on device" The Oracle docs note this on the ORA-27102 error: ORA-27102: out of memory Cause: Out of memory Action: Consult the trace file for details On the Oracle DBA-Forums, a user posts that he has been confronted by ORA-27102. He is unsure how to resolve this error because the database had previously worked, and ORA-27102 seemed particularly strange because he assumed he had plenty of storage on his machine. The error details were as follows: C:\Oracle\ora92\bin>SQLPLUS /NOLOG SQL*Plus: Release 9.2.0.5.0 - Production on Wed Mar 22 15:59:00 2006 Copyright - 1982, 2002, Oracle Corporation.

My OS is windows XP oracle version 9.2.0.5 I have NOT set LOCK_SGA in init.ora file.

Linux-x86_64 Error: 28: No space left on device I need to copy over my full tuning notes, but in the meantime, step 1 to look at with this error is shmall. cat /proc/sys/kernel/shmall MOS (301830.1) says to set it to shmall = total_mem_allocated_to_sgas / PAGE_SIZE to get PAGE_SIZE: $> getconf PAGE_SIZE Many other sites suggest setting it to shmall = shmmax/PAGE_SIZE Via Oracle Documentation, shmmax should be 1/2 physical memory. So, if you have 32G of memory and have a db with 25G allocated to the SGA, if you used the MOS calculation, with a page_size of 4096, shmall would = 6553600. Whereas if you went with the shmmax calculation, (assuming shmmax was set according to Oracle docs), shmall would = 4194304. And, what if you have a db that needs a very high PGA? If you're basing the server's memory allocation calculation on the SGA, would that not result in less-than-ideal parameter settings? Clearly both methods can result in significantly different results. Different enough that it makes me wonder if they both are potentially the proper way to do it, or if one version only produces the ideal results when the stars are lined up and your SGA is exactly what was used during testing and all other variables are set to default - and thus, it is not necessarily wise to always follow said method. I truly don't know as I haven't tested. (On my to-do list.) If anyone has test results, please share! In the meantime, I'm still starting with shmmax and tuning from there.. Like this:Like Loading...
