Job A on system A issues static SQL query to DB2 on system B. Which is faster:
1) DDF call to DB2 on system B via APPC over FICON CTC or 2) Local call to DB2 member of datasharing group w/ FICON CF links? Considering the overhead of DRDA protocol and independent enclave creation/classification/scheduling, etc., I would guess option 2 is more efficient in terms of CPU and response time. I'm just not sure how to determine in theory to what degree. db -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Vernooy, C.P. - SPLXM Sent: Wednesday, December 19, 2007 9:38 AM To: [email protected] Subject: Re: FICON vs ESCON CTC's "Mark Jacobs" <[EMAIL PROTECTED]> wrote in message news:<[EMAIL PROTECTED]>... > Is there any advantage in migrating CTC's from ESCON to FICON? > > -- > Mark Jacobs > Time Customer Service > Tampa, FL > ------ SPEED!!! XCF signalling via Ficon CTC links well outperform CF structures. Others will benefit similarly (VTAM).
