**nishantprabha** · 04-26-2009, 03:25 AM

Hi

We are restarting our server once in two days. otherwise DB is getting down.Please guide me how to resolve this.we dont want to restart it frequently(Requires restart once or twice in a month)

Server Configuration
----------------------------

32 bit windows server 2003 XP
4 GB RAM
Users connected : Around 150
Application using : JDEdwards
Database : Oracle

Total RAM=4gb (Oracle+OS)
Oracle => SGA+PGA=500+100=600MB

Also please guide me how can I utilize the remaining memory in a proper way.

Providing some of the parameters and values assigned.

Initialization parameters:
==================================
__db_cache_size 100663296
__java_pool_size 155189248
__large_pool_size 4194304
__shared_pool_size 255852544
db_block_size 8192
shared_pool_reserved_size 12792627
PGA 100 MB

Total System Global Area 524288000 bytes (500 MB)
Fixed Size 789692 bytes
Variable Size 442757956 bytes
Database Buffers 79691776 bytes
Redo Buffers 1048576 bytes

we are using SPFile

Thanks in Advance

you have said nothing there which indicated why you are restarting the server

**nishantprabha** · 04-26-2009, 05:55 AM

We are restarting DB because users are not able to connect to application (JDEdwards) or some times they are not getting datas from database.

So as an Admin I tried to check the enterprise manager, or Toad in server. It is showing Listner error which means that connection to database is lost.

So I will do a restart.
After that all the problem will be solved. Even I can access toad and enterprise manager.But this will continue for two or three days. Again same problem will affect and I need to restart again.Thats Y I doubted whether it can be the problem of any buffer cache or some other setting.

Please let me know whether u need the entire parameter list to check any values... Anyway I am attahing an Excel along with this, which has got the entire parameter and values.

**PAVB** · 04-26-2009, 09:18 AM

Any ORA- error message on the client side?
What you see in Alertlog?

**nishantprabha** · 04-26-2009, 11:18 AM

No ORA message.. thats y i cannot figure out what exactly happening...

I am providing all the parameter values below.Please let me know whether any important value is missing or not.

**PAVB** · 04-26-2009, 06:25 PM

Two items call my attention, #1 the use of Windows XP as the O/S for a production database server and, #2 the suspiciously small size of the SGA

Having said that I think you are looking for the root cause of the issue in the wrong place. It is hard to believe the system just stops working showing neither O/S nor Oracle messages. Nothing in Oracle’s Alertlog? Nothing in Windows’ Event viewer either? Really?

What happens if you recycle Oracle instead of powering down the server as original post suggests is the current standard procedure to deal with the issue.

**gtcol** · 04-27-2009, 01:00 AM

32 bit windows server 2003 XP
4 GB RAM
Users connected : Around 150
Application using : JDEdwards
Database : Oracle

Total RAM=4gb (Oracle+OS)
Oracle => SGA+PGA=500+100=600MB

Well, with 150 concurrent users, how do you expect to do with 500M SGA and a mere 100M PGA, where Oracle needs some memory, to maintain user session info. This is heavily undersized, i would say. See alert log, Windows Event Viewer as PAVB suggested. Also keep monitoring Perfmon continuously. Increase SGA, PGA to what is possible, at least 2G.

**mahajanakhil198** · 04-28-2009, 05:59 AM

what say abt listener log file?

**nishantprabha** · 04-28-2009, 06:33 AM

Please see the attached Listener log file.

this I have taken before restarting the server.

please let me know whether any issue is there with listener.
