Hi

Hi

I am running Red hat es 3 at my office since today the oracle shutdowns writing a log saying due to a ctp/ip error this service when down.

What my boss feels is some how the network software is corrupted.

Is there a way for me to uninstall the network part of redhat and re-install it back again? With out reinstalling redhat all over again

Thank

There's no point in taking any action until you have a better idea of what is wrong. You should look at the computer log files on both the client and on the server. You should do some network diagnostics such as pinging different computers on the network. Don't do anything until you know, or at least have a suspicion, about exactly what is wrong.

Hi

I have done all of those pinged to different machines and from machines works but with time outs and some times delays not at all continues, change the cable, NIC card, reconfigured, switch ports, but nothing helped.

Can you think of a reason why this is happening?

And further more can you tell me how to reinstall a corrupted part (system portion) of a redhat machine (Network service or some part need by redhat to work properly) hoping it boots with errors.

thank you

You may have to bring in a network and Oracle expert to diagnose your network problems. If you have looked at the system logs and the Oracle logs and done a lot of diagnostic testing, and you are still unable to pinpoint exactly what is wrong, then you would benefit from having a consultant come in and look at your situation. It is impossible to tell from reading your posts what is not working. For all I know it could be a problem with the user account accessing Oracle. There are just too many possibilities for anyone to make responsible suggestions. For example you said that you tried to ping the server but you didn't provide enough details. Did you ping the server from the client that is used for Oracle applications? Did the ping succeed or fail? If the ping failed did you read the /var/log/messages of the server to see if the packets were received? Have you pinged the client from the server? Did that succeed or fail? Did you read the /var/log/messages on the client after you tried to ping it from the server? Did it have any network related messages?

You see? Those questions need to be asked and answered. And those questions are just about using ping from the client and from the server. There are lots of other tests to perform. You have to see if both the client and server have total network failure or if it is partial failure or if the network is actually okay. You have to look at the Oracle server logs to see if there are more messages that could help you to understand the problem. If you are using unshielded twisted pair cables then maybe the hub is broken. All of these kinds of questions need to be answered before you can understand the cause of the problem. You may find that someone tripped over a cable and loosened the wires from the connector. It could look okay but actually have a loose connection to the connector.

I'm just trying to say that you need to understand the cause of the problem, in exact detail, before you can create a solution.

I wish that I could be more helpful but I think that you need to bring someone into your office to diagnose the problem.
