Two errors with a same data-job running on DataFlux server

[bzadnik]

Hello,

I hope you will be able to assist me.

I  have not  encountered these two errors so far on Dataflux server behaviour.
With same job doing scanning on the one table I have firstly received
following error:
1. FIRST ERROR:

ROOT][DATAFLOW_4_0]Node DATAFLOW_4 error: [33:EXPRESSION:Traspose PDP data] Expression Plugin - Expression Plugin - Seek in file failed..
2021-09-21T13:40:35,989 INFO [ROOT]Setting Execution State: STOPPING, Error message:(Process Flow - Job terminated due to error in one or more nodes. (DATAFLOW_4:0 - [33:EXPRESSION:Traspose PDP data] Expression Plugin - Expression Plugin - Seek in file failed..))
2021-09-21T13:40:36,006 INFO [ROOT]Process Flow - Job terminated due to error in one or more nodes.

Without any  changes, I have just restarted DataFlux DM Studio, and
than on the Data Management Server ran again same job and got a different error:

2. SECOND ERROR:

ERROR [ROOT][DATAFLOW_4_0]Node DATAFLOW_4 error: [38:SORT:Sort by key] Temporary File Library - Write failed, rc = 112.
2021-09-22T04:13:32,996 INFO [ROOT]Setting Execution State: STOPPING, Error message:(Process Flow - Job terminated due to error in one or more nodes. (DATAFLOW_4:0 - [38:SORT:Sort by key] Temporary File Library - Write failed, rc = 112.))

Do you know what these error(s) mean?

Thank you. Boštjan

Hello,

The first error message "Expression Plugin - Seek in file failed" indicates an expression node which uses some function that is trying to access a file is failing. Exactly which file depends on the code in the expression function. This could also be a problem with space available where te Expression node is trying to write.

The second error message "Temporary File Library - Write failed, rc = 112" is also typical of a lack of ressources.

Both seem to indicate a lack of temporary space. Can you check this?

Thanks,

Audrey

Hi Audrey,

thank you for your answer.

I guess you are referring to a disk space availability.

We have currently 12 GB free and a  6 vCPU permanent processors on the sever 

machine where I am running job.

But, results are written to Oracle database (exadata) that does not reside on same machine

and there should not be any problems regarding space availability.

Can you be more specifici which temp space do you have in mind?

Thank you.

Yes, I am referring to disk space. Especially TEMP space: it's not because the entire disk is not full that the space allocated for the temp is not full though.

What is your Expression node code doing exactly?

hi Audrey,

I have the same problem in a sort and/or clustering node. We tried to change the path of base/temp library to an other with more disk space but no change.How can we change the space allocation for this temp library (on the server and in local) ?

Thanks
