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  

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 memoryOSD-00034: additional error informationO/S-Error: (OS 8) Not enough storage is available to process this command.  

I've tried raising and lowering the memory but nothing works.  

Has anyone implemented AWE? If so, how did you get it to work?
