SQLNet tracing may be requested by Oracle Support when RMAN hangs and:
- 10046 trace on the target and catalog show both connections are idle with high waits on 'SQLNet message to/from client'
- RMAN debug trace shows a hang calling an internal routine (one that is NOT being executed AT TARGET or AT RCVCAT) eg
Typically, rman will be making a remote connection to a target or catalog but even a local connection will still use a BEQUEATH SQLNet protocol.
One of the main problems when generating sqlnet tracing is the large number of trace files generated - when tracing rman we are only interested in certain specific processes.
This article will show how to set SQLNet tracing and determine the exact sqlnet trace files to upload to support.
