Ora-27102: Out Of Memory Solaris-amd64 Error: 22: Invalid Argument
SVR4 Error: 22: Invalid argument Diagnosis $ oerr ORA 27102 27102, 00000, "out of memory" // \*Cause: Out of memory // \*Action: Consult the trace file for details Not so helpful. Let's look the alert log ora-27102 out of memory linux-x86_64 error 12 for some clues. % tail -2 alert.log WARNING: EINVAL creating segment of size 0x000000028a006000 fix shm parameters in /etc/system or equivalent Oracle is trying to create a 10G shared memory segment (depends on SGA/PGA sizes), but operating system (Solaris in this example) responded with an invalid argument (EINVAL) error message. 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 ora-27102 out of memory windows 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 this scenario, where as the application (Oracle) is trying to create a memory segment (10G) larger than 8G. Hence the failure. So, the solution is to configure the system with a value large enough for the shared segment being created, so Oracle succeeds in starting up the database instance. On Solaris 9 and prior releases, it can be done by adding the following line to /etc/system, followed by a reboot for the system to pick up the new value. set shminfo_shmmax = 0x000000028a006000 However shminfo_shmmax parameter was obsoleted with the release of Solaris 10; and Sun doesn't recommend setting this parameter in /etc/system even though it works as expected.
