ORA-27102: out of memory ora-27102 out of memory solaris tips Oracle Error Tips by Stephanie F. First solution by Mircea Vutcovici I got the ORA-27102 error upon instance startup: ora-27102 out of memory linux-x86_64 error 12 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 sqlplus process and here was theOra-27102 Out Of Memory Solaris 11
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 memory Linux-X86_64 Error: 28: No space left on device" ora-27102 out of memory windows 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. The resolution for ORA-27102 came when the user "reduced sga_max_size from 1.8g to 1g. restarted db and it is open now" but they were still unsure whether there could be more SGA than 2g in Windows XP, and what the OS limitation was. A replier answered the question i

Here is the error image. Any of you please suggest me, how i should execute this insert script in toad. P.S : since toad is connecting to remote machine I'm not able to run it with SQLPLUS. out of memory If any one knows option to do that, please let me know. If you need any more information, Please raise your hands in comment box i will provide you. oracle oracle10g sqlplus toad share|improve this question edited Dec 29 '15 at 4:38 asked Sep 8 '14 at 12:40 Wanna Coffee 1,66031736 This is not a programming question, probably will be closed. Normally you would upload such a big script to the server via FTP/SFTP and then log in via SSH and then run the script with SQLPLUS. –bpgergo Sep 8 '14 at 12:43 If this script is an insert script that contains multiple insert statements and if it is not an option to upload the script to the server and log in via ssh and run the script with SQLPLUS then I suggest divide and conquer. Split the script into smaller parts in a text editor until you get parts small enough for the TOAD not to throw outofmemory. –bpgergo Sep 8 '14 at 12:46 okay, whether we can have any query to run this script file in toad?? –Wanna Coffee Sep 8 '14 at 12:49 1 committing may also help –bpgergo Sep 8 '14 at 12:57 1 Of course you can connect to a remote server using SQL*Plus.
of memory Solaris-AMD64 Error: 22: Invalid argument On asking to the team, came to know,that there was some issue, which they were not aware of.So it was time to investigate🙂 Check the Alert log Starting ORACLE instance (normal) Sun Jun 20 17:00:06 2010 WARNING: EINVAL creating segment of size 0x0000000180004000 fix shm parameters in /etc/system or equivalent Oracle is trying to create a 6Gb shared memory segment, but operating system responded with an invalid argument (EINVAL) error message. As the alert log suggested, "fix shm parameters in /etc/system" and showed "creating segment of size 0x0000000180004000".Converting the hex value ("180004000" ) in decimal comes up to "6442467328". As suggested, changed the value of set shmsys:shminfo_shmmax to "6442467400" in /etc/system and rebooted the server.Again,the same error -bash-3.00$ sqlplus / as sysdba SQL*Plus: Release 10.2.0.4.0 - Production on Sun Jun 20 17:15:03 2010 Copyright (c) 1982, 2007, Oracle.
