globalMap.get returns null

Anonymous — Fri, 08 Nov 2019 10:28:19 GMT

Hello,

first sorry for my bad english.

I implement a Tmap which has 2 output (in order to get the rejects of inner join in the second output). Those 2 outputs go to the same Oracle table with 2 components (tDBOutput_1 and tDBOutput_2). I link a "OnComponentOk" from tDBOutput_1 to a tfixedFlowInput.

tMap --- out1 ---> tDBOutput_1 --- OnComponentOk ---> tFixedFlowInput_1

\_ --- out2 ---> tDBOutput_2

All The rows from out1 and out2 are correctly inserted in the DB table.

In the tFixedFlowInput_1 I can only get the rows inserted from tDBOutput_1 with ((Integer)globalMap.get("tDBOutput_1_NB_LINE_INSERTED")) but ((Integer)globalMap.get("tDBOutput_2_NB_LINE_INSERTED")) is always null.

Do you have any idea to find a solution?

@ktox ,can you show job design?

I show job here job_design, tmap and tfixedflowinput

Thanks

@ktox , from DB2 output component is inserting any data? if yes then you need to use on component on from tDBoutput_2 to tfixedflowinput. since in your design you use from tDBoutput_1 .

Yes, tDBOutput_1 inserts 10000 rows in table and tDBOutput_2 inserts around 2000 rows.

in tFixedFlowInput_1 -> ((Integer)globalMap.get("tDBOutput_1_NB_LINE_INSERTED")) is 10000

but ((Integer)globalMap.get("tDBOutput_2_NB_LINE_INSERTED")) is null.

I would like to have : ((Integer)globalMap.get("tDBOutput_1_NB_LINE_INSERTED")) + ((Integer)globalMap.get("tDBOutput_2_NB_LINE_INSERTED"))

But the job throws NullpointerException because of tDBOutput_2.

@ktox , you can use on Subjob ok from the main component of job to tfixedflowinput and it should work. can you try it?

It works fine!

Thank you
