ORA-27102: out of memory
Linux-x86_64 Error: 28: No space left on device
There are 64G physical memoray avaliable. shmmax is set to 52G But still its not possibel to start the Oracle instance with more than 30G SGA. Solution: kernel.shmall is set to small.
cat /proc/sys/kernel/shmall
8248733
getconf PAGE_SIZE
4096
This means that only 8248733 memory pages can be allocate. 4096 x 8248733 = 32G To allocate 50G we need to set shmall to at least 13107200 Comments (3) 3 Comments » I know this posting is over two years old, but I've been looking for a straight forward answer to this same question for over 2 months. We increased the memory on one of our Linux X64 servers to 32GB, but I couldn't get all of the databases I wanted started up on it (each had 2G SGA and 500M PGA in it's initSID.ora file. There are 9 databases. So I finally found this posting and viola(!) All of the DB's started up and opened without the memory error. In fact, I went back through them and increased the SGA to 3G and the PGA to 750M. Changing the SHMALL setting did the trick. NOTE: The SHMMAX kernel parameter was increased prevously too. Thank you for the posting and for making it so even someone like me (who needs clear and simple instructions) can use it. Comment by SL Brower -- August 2, 2012 @ 7:20 pm Helped me out a lot!
