Please let me know the difference between parallel Transformer and BASIC Transformer in parallel job. Which one is useful under which scenario.

Thanks.

Visibly, there is no difference other than mentioned in the documentation. BASIC transformer has access to BASIC functions (functions that you could use in a server job's transformer).

When your situation demands any BASIC function in a PX job (that are not available in your PX transformer), then you could go for a BASIC transformer stage.

Interview question?

No, it is not for interview.

I am using 5 BASIC transformers in a parallel job (needs to call some server routines & macros not available in parallel transformer). The job fails with the error :

node_node1: Fatal Error: Unable to start ORCHESTRATE process on node node1 (x40bdwas01): APT_PMPlayer::APT_PMPlayer: fork() failed, Resource temporarily unavailable

The job however worked with parallel transformer without those calls.So, my dbout is on the BASIC transformer.

Please advise.

This would have been a much better place to start then, rather than the extremely generic "what's the difference" question.

I already have one started with 'ORCHESTRATE error ', but no one has responded to it yet.

This one?

That's probably because there's zero in the way of detail in it, at least here you've added some pertinent information re: the job design.
