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 with maximum memory segment value that can be linux-x86_64 error: 12: cannot allocate memory 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. On Solaris 10 and later, this value can be changed dynamically on a per project basis with t

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 the error: shmget(0x37ed6a3c, 1243611136, IPC_CREAT|IPC_EXCL|SHM_HUGETLB|0600) = https://blogs.oracle.com/mandalika/entry/oracle_on_solaris_10_fixing -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" The Oracle docs note this on http://www.dba-oracle.com/t_ora_27102_out_of_memory.htm 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.
