RE: Indexes vs Logical Files

Thanks everyone for the suggestions!

Jim - what am I looking for? Some of my LF were created 20 years ago, but likely compiled relatively recently.

OEBOX1 is a logical file.. DSPFD? Is this what you're referring to?

Access path . . . . . . . . . . . . . . . . : Keyed
Access path size . . . . . . . . . . . . . : ACCPTHSIZ *MAX1TB
Access path logical page size . . . . . . . : PAGESIZE *KEYLEN
Maximum key length . . . . . . . . . . . . : 36
Maximum record length . . . . . . . . . . . : 131
Keep in memory . . . . . . . . . . . . . . : KEEPINMEM *NO

Does this mean the page size is 36?

Charles - thanks for the explanation. The "Explain" portion in RSS is a bit overwhelming for this SQL view. I worried about burying views within views.

And you're right about trying it... sometimes the suggested indexes work wonders, while other times they do very little.

I believe at one time that was true. Since then the CQE has been displaced by the SQE.

I would be looking at those logical files since they are most likely older to see the page size (as some have suggested) and other attributes. Might be worthy of a rebuild with newer parameters.
