"Have you seen ORA-03113 before?"
Yes

"Why did we get this error?"
I don't know.  It could be a big variety of reasons.

"How to fix it?"
That is not so easy.

The two most-difficult Oracle errors to deal with are:
ORA-03113: end-of-file on communication channel
and
ORA-03114: not connected to ORACLE

The reason these two are the most difficult to deal with, is: the connection to the database server is broken at this point, and you cannot handle these with an "exception" section.

Unfortunately you have to figure out what caused this error, and fix that problem.  There certainly is *NOT* just one cause for this, or one easy fix.

If you need us to help you figure out what caused this, you will have to give us a lot more information, like:
1. your database version
2. your server O/S
3. your client or application server O/S and Oracle version
4. which application do you see this in
5. is this a new procedure or application, or an exisiting one that used to work, but now gets this error
6. do all clients get this, or only some
7. does this happen consistently now, or only randomly

Some of the situations in which i encountered this wierd error are : -

1. Trying to store more chars in a variable than its max. size.
2. Trying to display data much more bigger than the output buffer size.
3. Trying to pass an invalid type of argument in a function call.

Check for these symptoms in ur program by debugging it and try to fix them.

Also, check out a very brief description of this error at http://ora-03113.ora-code.com

how do you connect to database?
eg. ODBC and JDBC have some parameters saynig, how long can you be connected to DB, how long at maximum can one statement be executed.
but in most cases the error means some network problems or application error hiting some oracle bug

I have met this error on Linux/Unix platform after installing Oracle and changing the Kernel of the OS.
Also can arise after installing additional software on the box.

One other thing not mentioned...

Are there any errors in the alert log that correspond to the time this happened?

Would you please post your SQL?

As far as I can remember, we had the same error before with a SQL which count(*) from a view.

If you have similar SQL, try to change count(*) to count(1)

There are many other reason might cause this error.

Good Luck

Share with us the version of Oracle. Sometimes patches remove bugs.

raise a tar ( SR ) with oracle and they will let you know what patch you should apply depending of your db version, platform, etc.

Thanks
