SrvCtrl eats my memory day by day

[HanyHamed]

hi all
my problem is simple:
- i have WINNT server for ORACLE 8i database only. it is part of a control system of the Steel Plant. it has no other custom services/application running.
after each restart of the server, the SrvCtrl occupies only few hundred KB, but day after day it starts to eat the memory. i record that increment of memory usage as around 3-7 MB per Day. now for example it is 60 MB of (Mem Usage).

this means that i have to restart the server each 5-6 days ( not acceptable ) specially it is an online control system.

Please could some one help me.

Is your program opening connections and not closing them?

 

[HanyHamed]

how i can know that?

 

[johnwm]

Is this a commercial program or your own?

If it's a commercial program then speak to the suppliers as it appears to have a memory leak.

If it's your own then check out xwb's suggestion. Any Objects (such as Data connections) need to be closed and set to Nothing after each use. The method will depend on the language you're using

Good Luck

i use that server as ORACLE database only.
no other programs or control application are running.

 

[johnwm]

Sorry I should have been clearer with my previous question. The problem is more likely to be the front-end. What is your front-end program?

Good Luck

i using delphi for models programming but all the applications are located in another server, also the user interfaces are located in user's PC's
is that you mean by front-end program?

 

[johnwm]

Any applications that use that server for data could be the problem. You will need to use a process of elimination to find out which. If you are writing your own Delphi code then that's where I would start looking for unclosed database connections.

Good Luck

HI IRstuff

what do you think?! instead of saying what i know, try to find an answer, if you don't have any, don't volunteer to spread out usless news, i am not plying,i am not in casino, i have a serious problem need to be solved.
that is enought for now

 

[IRstuff]

I'm simply warning the members of this site not to waste their time going over old ground, as a courtesy.

Since you have a problem with the Oracle software, why have you not contacted their tech support?

TTFN

 

[HanyHamed]

it is not oracle because i am monitoring ORACLE services and i execlude oracle from the subject. i am sure it is WINDOWS. i already contact microsoft but stupid automatic answer is all the time activated. that is all.
sorry if i was aggressive.

 

[IRstuff]

Do you nkow for sure that you need it?

Have you tried to turn it off?

TTFN

 

[HanyHamed]

i think windows mainly use it as it is one of its core.
i don't think it is a good idea to turn it off.

 

[IRstuff]

Not sure about NT, but it's NOT anything that's part of XP.

Plus, there are TONS of services that Microsoft turns one that are mostly useless. Even the DNS client can be turned off with nary an ill effect.

TTFN

 

[johnwm]

I don't believe that it is a core windows service. srvctrl is a cluster-aware monitor product associated with Oracle. As I said before, this is almost certainly a problem induced on your server by one the client programs.

Good Luck

YES I am sure now it is not a windows service.

thank you all for your valubale advices specially IRStuff
