Hi I have performance question 1. If we have a big PF such as 500,000 records and have LF which was using for both online and batch programs. And sometime many program use it at the same time. The PF is very active one. What (and why) should be use for parameter matainance access path between *IMMED and *REBLD? 2. OPNQRY or LF should be use in a picture of performance? TIA.
