If you've tried to bring the database up once and received this error, you will need to reboot the host to clear out memory. Set the db service to not start upon reboot so you can control the restart when the host is back.
Ensure that your settings are not too large for the amount of memory you have available also. Remember, db_block_buffers is the number of blocks, not the size of the pool. That's bit me more than once.

Subject: Implementing ADDRESS WINDOWING EXTENSIONS (AWE) for increased memory
I'm trying to implement ADDRESS WINDOWING EXTENSIONS (AWE) to take advantage of all of the memory on my server. The server details are: Windows server 2003 enterprise edition, 4 processors, 8 GB memory, Oracle 10.2.0.1.
I tried to implement awe according to metalink note 225349.1 but my instance is not coming up. I did the following:
- added switches /PAE and /3GB to the boot.ini
- removed sga_target from the spfile added USE_INDIRECT_DATA_BUFFERS=TRUE to the spfile
- added DB_BLOCK_BUFFERS to the spfile
The error I get when I start the database is :
ORA-27102: out of memory OSD-00034: additional error information O/S-Error: (OS 8) Not enough storage is available to process thiscommand.
I've tried raising and lowering the memory but nothing works.
Has anyone implemented AWE? If so, how did you get it to work?
