There is a little hint about setting shm parameters in /etc/system. Prior to Solaris 10, shmsys:shminfo_shmmax parameter has to be set in /etc/system with maximum memory segment value that can be created. 8M is the default value on Solaris 9 and prior versions; where as 1/4th of the physical memory is the default on Solaris 10 and later. On a Solaris 10 (or later) system, it can be verified as shown below: % prtconf | grep Mem Memory size: 32760 Megabytes % id -p uid=59008(oracle) gid=10001(dba) projid=3(default) % prctl -n project.max-shm-memory -i project 3 project: 3: default NAME PRIVILEGE VALUE FLAG ACTION RECIPIENT project.max-shm-memory privileged 7.84GB - deny - system 16.0EB max deny - Now it is clear that the system is using the default value of 8G in

Fundamentals Oracle Errors Performance Tuning ASM Datafiles & Tablespaces Exadata Database Startup On Solaris 10 Fails With Ora-27102 Out Of Memory I have Solaris 10 system with RMAN http://www.dbas-oracle.com/2011/08/database-startup-on-solaris-10-fails.html 16G size. I am starting database with 6G of SGA size but startup fails with the following errors. SQL> startup ORA-27102: out of memory SVR4 Error: 22: Invalid argument And the https://www.experts-exchange.com/questions/22919982/Creating-Database-10-2-in-Solaris-10-error-ORA-27102-out-of-memory-SVR4-Error-22-Invalid-argument.html alert log shows something similar to the following. WARNING: EINVAL creating segment of size 0x000000002a000000 fix shm parameters in /etc/system or equivalent Cause:Solaris 10 sets the shared memory segments on out of projects, and it is suspected to be caused by projects not being setup correctly. Because of this,there is not sufficient SHMMAX available for Oracle to allocate the SGA, so startup fails. Solution:It is still permitted in Solaris 10 to set the limits in the /etc/system file, which willallow database startup in the interim, until canresolve the issues with projects settings. Log in out of memory using root user. For example, a sample /etc/system entry setting SHMMAX = 6GB. set shmsys:shminfo_shmmax=6442450944 set semsys:seminfo_semmni=1024 set semsys:seminfo_semmsl=1024 set shmsys:shminfo_shmmni=100 Database started with above settings ok, and missing project settings in this case were the following. 1 In case adding new Project: # projadd -c "Oracle" 'user.oracle' 2 In case modifying existing project: # projmod -s -K "project.max-shm-memory=(privileged,6GB,deny)" 'user.oracle'. I have applied both of the above ways but the issue still persists. At last I restart the database server and it works for me.
