Hi All, we have been receiving the following error on some of our jobs:

main_program: ERROR: gethostbyname(dcob04) returned null; node node1 cannot be used.

If the job is re-started it runs fine.

What's common about the jobs that are failing are they all read from the same Oracle Database. Jobs may run fine for weeks then fail.

Jobs are simple and similar

Sorry here is some extra info and configuration file:

main_program: Unable to define node 'node1'.
Probable configuration problem; contact Orchestrate system administrator.

Wondering this may related to Linux. We are running Red Hat.

Do you have Null handling in place?
