James, I'll assume that this program reads FILE1 and chains to FILE2 to update it. The first thing I'd do is try to index or sort FILE1 so that it's in the same basic order as FILE2. This will allow the system to cache the reads/updates to FILE2. This change shouldn't require changing the update program. A couple of questions: Are there multiple updates in FILE1 for records in FILE2, or is there only one update in FILE1 for any record in FILE2? Are the updates changing fields that are used in an index over FILE2? Steve Morrison Beacon Insurance 940-720-4672 -----Original Message----- From: James R. Newman, CDP [mailto:newman400@xxxxxxxxxxx] Sent: Thursday, October 14, 2004 11:32 AM To: Midrange L Subject: Setting parms in CL for PF 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. 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. James R.
