I would like to handle an OracleException thrown when my network/database connection is interrupted, where can I find out what error codes I might can receive?
I guess since we are talking about a connection interruption these would be technically TNS errors such as ORA-12560 "TNS:protocol adapter error." But I have noticed a couple others depending on where exactly the connection is lost and would like to get a full list.
Take a look at Oracle Database Error Messages 11g Release 1 (11.1). And here are the search results for TNS errors.
