DSXchange

Hi,

Am running a job on DataStage PX 7.1.
This job has a transformer, followed by lookups over multiple files (in one lookup stage) and another transformer, followed by a funnel stage.

The main error messages obtained are as follows -

subArgs={asc}}},1: Fatal Error: mmap failed: Not enough space

subArgs={asc}}},1: Failure during execution of operator logic
subArgs={asc}}},1: Output 0 produced 0 records
buffer(1),0: Failure during execution of operator logic
buffer(1),0: Fatal Error: waitForWriteSignal(): Premature EOF on node czhs0255 Error 0
buffer(2),0: Failure during execution of operator logic
buffer(2),0: Fatal Error: waitForWriteSignal(): Premature EOF on node czhs0255 Error 0

Besides, am unable to view the full log file as the number of log messges a lot and the director shows only which it can accomodate.

Appreciate any inputs/ help on this.

Thanks in advance.

Regards,
Nitin

The Director has a filter which, by default, shows the 100 most recent events. You can invoke the filter via Ctrl-T, by choosing Filter Entries... from the View menu, or by right mouse click in the Log view and choosing Filter from the pop-up menu.

Can't really help much with the PX problem, except to note that the first error message indicates that something has run out of allocable memory.

Hi Nitin,

We used to get similar kind of errors when running our jobs on 4 nodes but we were able to run the jobs successfully on 2 nodes.

Are you running on single node or multi node? If it is on multinode create another configuration file which uses lesser number of nodes.

Why don't you test using a simple job. Are you using a single lookup stage to lookup multiple datasets?

Why dont you search this forum on iomap. There was a discussion on this 2 weeks back. It might help.

Lastly try to view all the datasets that you are using for lookup.
