Re: Multi-tasking to reduce time

The idea of dataQ seems good.
you can also explore another way : add a trigger to the control file.
And look at the transaction pgm : end by return without LR

Subject: Multi-tasking to reduce time


I have following scenario.

Control program reads through a control file (control file has list of
transactions to be processed) and calls programs as below:
CREATE_TRAN_INFO -> this program writes record in CREATE_TRAN_INFO phy. file
per transaction
CREATE_CASH_INFO -> this program writes record in CREATE_CASH_INFO phy. file
per transaction
CREATE_COLLAERAL_INFO -> this program writes record in CREATE_COLLAERAL_INFO
phy. file per transaction
(Lets call these as work programs)
If all work programs run successfully, control program flags transaction as
processed and commits.

This is taking about 20 min. to process around 40,000 transactions. I need
to reduce this by 40% to meet SLA specified. Can I get some ideas on how
best can this be achieved.

I could think of creating IN and OUT data queues for each work program. Take
them out (from inline call) to a separate job that runs in batch. Control
program feeds these programs through IN data queue and picks the processed
part from OUT and also writes to the respective phy. file.
I am of the opinion that there would be too many dynamic calls to QSNDDTAQ
and QRCVDTAQ, not sure if the objective would be achieved.
Just for note, all work programs can run independently at the same time.

Any help is greatly appreciated.

Best rgds.,
