I've got the following error in my listener.log file:
---
11-JUN-2003 15:15:49 * service_died * order1 * 12547
TNS-12547: TNS:lost contact

TNS-12560: TNSrotocol adapter error
TNS-00530: Protocol adapter error
32-bit Windows Error: 2: No such file or directory

When I looked up the error TNS-12547, it says "Partner has unexpectedly gone away".

My question is: is this "Partner" the Oracle instance or the client attempted to make a connection?

Also, has anybody encountered the above error before?

Thanks,
