Job now gives fatal error re TCP protocol

[gerardp]

I'm running a job which extracts data from several Oracle 8 databases (using the DRS stage). The job has always worked in the past but now gives the following fatal errors:

buffer(5),2: Failure during execution of operator logic
buffer(5),2: Output 0 produced 0 records
buffer(5),2: Fatal Error: Cannot find protocol entry for tcp protocol!

I've tried other jobs which also access the same Oracle 8 databases using the DRS stage - some work and others give the same fatal errors.

The source databases appear to be working okay and allow connection via SQL*Plus.

Any help appreciated.

Getting the same errors.

Admin folks claim the server is busy!

Any insights? I'm running version 7.5x2 on Windows, which probably explains a lot.
