I just applied the following 2 coomands and restarted database without any
issues. It is Window 2003 with 4GB ram. No other changes made to any other
parameter or any file.
SQL> ALTER SYSTEM SET SGA_MAX_SIZE = 1500M SCOPE = SPFILE;
System altered.
SQL> ALTER SYSTEM SET SGA_TARGET = 1500M SCOPE = SPFILE;
System altered.

(AWE) for increased memoryCC: oracle-l@xxxxxxxxxxxxxxxxx the ML Note:The size
of this window is defined by a registry setting in the HOME key for Oracle
(HKLM\Software\Oracle\Homex) called AWE_WINDOW_MEMORY. By default,
this value is 1GB, so if this value is not set in the registry,
AWE_WINDOW_MEMORY will be 1GB. This is set on a per instance basis.

Hi, 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 spfileThe 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? Thanks,David GrosserDBANSTAR Electric
