    You could check Separate launcher processes option in launcher admin.
    Next, please change the value of MaxThreads parameter in dtx.ini file.

    After that each map will run in separate process with multi-thread.

    Hi Silver is there any other procedure of implementing Multi threading in WTX other than using Launcher.

    Thanks & Regards,

    ; server, the greater the number of maps that can be executed concurrently.
    MaxThreads=20

    check in dtx.ini
    by default is multithreading.. if u do not want this.. u can set it 1..
    MaxThreads parameters...need to be 1 if u dont need multithreding

    All...correct me if i am wrong...

    Hello, Sunil.

    You can also develop java-based program with the SDK of WTX to do it.
    But, it's not the best choice for it. For performance, launcher is a good choice in my opinion.

I implemented a crude method for our inquiry job by splitting the large input file and calling a second batch job on our 2-processor VM environment to translate each half into the many small 270 files our trading partner can handle. Batch run time dropped from 150 to 34 minutes.
