Send Email Procedure

Question

Hello,
I've tried to run the code below (to send an email), but I keep getting an error msg. (ORA-03113:end of file on communication channel).
Any thoughts on how to overcome this error?

An ORA-03113 is symptom of an error and is in itself a totally meaningless message for determining the error.
An ORA-03113 is created by the client driver - it's not an error returned to the client by the server. This client error message simply says that the client has discovered that the Oracle Server Process that was servicing it, can no longer be communicated with.
Why?
The usual reason is that the Oracle Server Process that was servicing that client session crashed. When it did so, it took the "communication channel" down with it. This now results in an ORA-03113 on the client when the client attempts to "talk" to its server.
When an Oracle Server Process crashes, there should be traces of that - a message in the instance's alert log file recording the crash and specifying what the trace/dump file name is that was created for this crashed process.
Find that message and post your problem, with that message (full error details) in the [url http://forums.oracle.com/forums/forum.jspa?forumID=61]Database - General forum.
