Question

ORA-03114: NOT CONNECTED TO ORACLE

Asked by: plq

I'm running a long job from a web application with a IIS / vb.net mid tier and an oracle backend.

The web app runs in IIS as high isolated.

After many minutes (not sure how many yet), the thing comes back with ORA-03114: NOT CONNECTED TO ORACLE

Are there any configuration parameters either in IIS or ORACLE or other things I can set that might fix this?  

thanks

Hi,

can you check your alert log for when this happens?  it sounds as if there might be a server error and the database is dumping your conection.  if this is the case, there will be an entry in the alert log with reference to a tracefile that will contain more information.  you will need to know when the server dumps your connection tho'.

the alert log is located : select value from v$parameter where name = 'background_dump_dest'

let us know what it says ( if anything )

good luck :)

Hi Richard.

Thanks for this. The sql gave me
F:\oracle\admin\DBNAME\bdump

So I went there and theres a alert_dbname.log which hasn't been updated for 7 days, I checked its contents as well and thats also 7 days old at the bottom

Other than that theres trc files the latest of which is 3 days ago.

thanks
Paul

It seems that your database is not opened.
Can you establish a connection using SQL*Plus ?

 

by: plqPosted on 2006-10-17 at 06:39:59ID: 17747493

The error happens when we import a large file using our software. The process is constantly pushing data into oracle. Technically its running through IIS

When we use a smaller file (< 5 mins load time) it loads ok and completes. There's some kind of timeout going on I think

Hi,
  What is the profile of the user? Does it have any CPU limits or any other limits? If you have any limits, then please try to give unlimited resources and give it a try.
Please post the complete error message. Sometimes, it is possible that we get only the first line, which will be misleading.

Badri.

Nope. I made it fail again and the latest trc or any file in those folders is dated 4 days ago.

Yes I can query the database fine from sql plus or from my own little "query analyser" program written in vb

Can you tell me how to check this ? I am not familiar with oracle - thanks

Hi,
  Please check, if there are multiple connections in the programme. Please use some debug statements to print the connection string where it is failing.
It is possible that you have multiple connections and the first connection opening is fine and one connection opening is failing becuase you have specified wrong SID or something.
HTH

Badri.

No, the entire code runs under a single connection

Points coming up... but the answer is in the above thread

Please note, for anyone trying to analyse NOT CONNECTED TO ORACLE in future, the cause in this case was a previous error that wasnt correctly handled. (end of communication error), which drops the connection and then not connected to oracle is raised on a subsequent query.

thanks
