Improve the performance of the RPG program - Tip1

Post  maran on Wed May 29, 2013 11:40 am

One way to improve the performance of the RPG program is eliminate the unused fields(Work Fields and File Fields) so that static storage will be reduced.

Elementary Fields and Advanced data items like Arrays and tables use static storage, so reducing the amount of static storage of program takes improves overall efficiency.

If we are not using all the fields from the PF then consider creating LF with the required fields. No need to worry about the effect of extra access paths on the system. If the access path matches one that already exists, the system will share it, maintaining only one access path for both files.
