DataStage® Release: 11x
Job Type: Parallel
OS: Unix
Hi,

The parallel jobs are aborting with the below error-

main_program: APT_PMaddrInfoFor(): getaddrinfo(host = #hostname#, port = ) failed with error -2 - Name or service not known: node #hostname# cannot be used.

Please note: I have replaced the actual host name with #hostname# in the above error.

Has anyone encountered a similar error? Please help.

Thanks,
Lavanya

Let's get some additional information. Is this affecting all jobs or just certain ones and if so, what do they have in common? Was everything working before and this a new error and if so, what changed (that you know of) that started this error to appear? Is your hostname correct and accessible?

Seems to me it's either a problem with your config file (were changes made to it or them?) or something in the topology changed. Wondering about work on your O/S like patches or firewall

When there is an unresolved parameter name, like #hostname#, in an error message, it usually signifies that that parameter has not been added to the job. Possibly components have been copied from ...

Ray - I believe this means they added the ## to the error message, not that it was unresolved. Lavanya, can you please clarify?

Yeah chulett... your are right. I have added ## only in the error message.

Yes, all the jobs are aborting and they were working fine before.
The hostname is correct and we are able to connect to the host through designer and administrator clients. There are not changes in the config file as well.

Did you guys code Node restrictions in your jobs?

open the job and examine each stage to see if some yahoo is limiting the execution of a stage to a particular node name.
