RE: Limiting Oracle Memory

so....a PL/SQL table?.....can you say more about the code in question without violating the cryptic inner sanctum of Dulcian?

DBMS_PIPE.down('Ross');,

        Thanks for not destroying me with your mental powers:) I am concerned
about the size because it is completely hosing the machine. The worst part is, it is ONE connection that is doing it. No one else is connected to the db, but once this migration begins, POW, the memory goes to town and the machine eats it.

        So what I was hoping to do was set a limit on Oracle, let it have 600 megs
and finish the job. Yes, it would probably be slower, but at least the server wouldn't die. Once it dies that's it, it has to be done all over again. I am going to talk to the developer and see if we can do this whole thing differently, unless I can figure out how to use ora_workingsetmax!!

        Thanks again:)
Kev

1. I *like* NT, actually.
2. that's "DBMS_PIPE.down('Ross'); to you, Buster"
3. oracle, as a process, should include EVERYTHING on the box having to do w/Oracle with the exception of the listener. Including user connects, i believe....700MBytes is not at all large in that context....

Do this: track user sessions and memory over time.

if they grow commensurately...then there is no leak.

if there are monotonic jumps in the latter w/o any in the former, you may well have a leak, and you'll need to move to the thread level to find it, likely.

I am sure Jared and Mladen will be glad to help you with deep internal NT questions. <EG>

Hi all,

        I have a procedure that seems to be bringing my server to it's knees.
Winnt, Oracle 817 (Pipe down Ross:))
Anyway, what happens is a pl/sql table is placed into memory and then later on it will be written to the disk. However, by the time the process is about to get to the writing part the machine is dead. The Oracle.exe process is well over 700MBs and the Virtual Memory is over a gig and a half!! Is there anyway for me to limit this, I tried using the registry entry ORA_WORKINGSETMAX, however that doesn't seem to work. Has anyone used this setting? Are you just supposed to put a number in the entry? I put 600 but nothing happens. Any help would be greatly appreciated.
