Setting parms in CL for PF

I also posted this on Midrange-L but after thinking about it today it's really more of an RPG question...maybe.


I've got a 9406-600 running V5R2 and have to run a large update job about once a month. File1 is a sequential, non-keyed PF containing about 18 million records of updated "current" information. File2 is a keyed PF "master" with 18 million+ records that will be updated from File1. File2 has 1 logical. I'm reading a record in File1 and chaining to File2. If no record is found, it writes to File2. If record is found, it then checks about 5 fields and if the fields are identical in both records, no update is performed. If they're not the same, the info from File2 is moved and written to File1.

A friend suggested changing some of the OVRDBF parms to help processing go faster, such as FRCRATIO and NBRRCDS. Any suggestions on how to set these parms? For that matter, any suggestions on how to speed up the update process? TIA.
