setting parameters

[kavuri]

Hi,
I am having various jobs. I would like to set parameters for database name, user, password, db2 instance name, node information. I want to write the values into a flat file and read them from that flat file.
Here can I do that by running any script, like before jobsubroutine.
I may miss some sequence, please suggest me what the flow is.

Thanks
Kavuri

Be systematic and painstaking. Make a checklist.
