Re: Manual mem management in 10g

Michael, I could easily be wrong but I think you are getting 04030
errors because you have allocated too much of your total available
memory to the SGA and do not have enough left to be allocated to the
PGA's of your user sessions.

Essentially, the DB Creation Asst was only going to use 40%, which we thought was quite low, of it's possible 2GB so we decided on 80% since all this server does is this 1 instance. So it came up with 1.2GB for sga and 400MB for pga.


 Have your tried reducing your SGA_TARGET
to say 800M or 1G and seeing if this eliminates the 04030 errors while
still allowing the database to perform well enough?

That is the only thing support has suggested (other than the 3gb switch) but they haven't given me a practical way to do it yet. You can only reduce sga_target by the difference in your current amount and the min sizes of the parameters that sga_target controls. sga_target is 1200MB, the sum of min sizes is 1188MB so I can only reduce it in 12MB steps it seems. Now perhaps this is really what I need to do (can't do it all at once), but support has never responded back if there's a more appropriate way to do it (after several updates of my SR asking for clarification).


Why can't you use the -3G or better yet /PAE switch to make more than 2G
available?

It isn't supported by MS in a production environment on Standard Edition unless the app vendor (Oracle) has tested it. Oracle hasn't responded about that either.
