This defeats the whole point of using projects as the workaround just changes things on a system wide basis instead

of resolving the actual project configuration issue. There's also no guarantee this method will work in later updates of Solaris 10 as the functionality has technically been obsoleted by projects. You may be told this is a known bug, Oracle bug ID 5237047 - Incorrect system requirements for Solaris 10, and is actually a bug in Solaris 10. You'll probably be told to implement the changes in the above Metalink document. As above: DON'T.

You may even be told this is a known limitation in Solaris 10 in that you can't have a shared memory segment of more than 6GB, and once again referred to the workaround in the above Metalink document. As above: DON'T. Believe it or not, I heard all three of these in one conference call this weekend and from what I can tell this is probably due to a complete misunderstanding of how projects work in Solaris 10 (ie a lack of knowledge) or due to some very bad documentation in Oracle's bug/call system. However, this post isn't all about what not to do, but rather how you go about resolving this issue. In short, you need to change the shared memory allocation for the particular project assigned to your Oracle user or group, depending on which you've chosen to implement. There is loads of information on setting up projects on docs.sun.com and Sunsolve, but if you're looking for information specific to Oracle and this error, then check out this post in Mandalika's scratchpad. It provides clear succinct and correct details on changing the shared memory settings needed to get your Oracle database/instance running. — Published 01 July 2008 Copyright © 2005 - 2016 Colin Seymour All rights reserved.

of memory Solaris-AMD64 Error: 22: Invalid argument On asking to the team, came to https://aprakash.wordpress.com/2010/06/26/ora-27102-out-of-memory/ 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 http://www.dbaglobe.com/2013/05/quick-way-to-fix-ora-27102-out-of.html 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, out of 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 out of memory 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.

After few searches on google, got the command to change the value.Logged in as root (luckily had the password :)), and used the below command bash-3.00# projmod -s -K "project.max-shm-memory=(priv,6442467400,deny)" oracle Then, tried to startup the database,but again failure.Checking back the parameters -bash-3.00$ cat /etc/project system:0:::: user.root:1:::: noproject:2:::: default:3:::: group.staff:10:::: oracle:100::::
