Pass value from child job to parent job both running as independent process

[Anonymous]

Hi,

Googling gives me to return value from child to parent job both running under same process through buffered output.

My design is from parent job I am running parallel child job, where every child job will run as separate process(for max utilizing of resources to process huge volume of tables) and has to return the last processed id back to parent job.

Could you kindly suggest how this can be achieved.

Thank you

Hi,

I have also tried routines with static variables.

package routines;

public class testMyRoutineDemo {
public static String myLastProcessedID_1;
public static String myLastProcessedID_2;
}

Populated the value in child job:

routines.testMyRoutineDemo.myLastProcessedID_1 = "123"

In parent job:

in tJava - 

System.out.println("last_customer_id=" + routines.testMyRoutineDemo.myLastProcessedID_1);

Could you kindly suggest.

Thanks.

I am attaching the screenshot of the flow.

Please suggest if there is a possibility to pass value from child job to parent job running as independent process.

Thanks

You need to use a file to pass values from child job to parent when running as an independent process.

Will it be possible to share through temporary file?

Why not, as soon as you don't select the "Remove file when execution is over" option.
In this case, the parent job will be in charge to delete this file.
For lisibility, I prefer the parent to pass filename in which the child job will have to put data.
