Hi Im not a performance analyst, Im a CICS & MQ Sys-Prog. I dont understand this new "paradyne".
Some Back ground March 1 Our Development Team introducd some new functionality. The following week we were plagued with multiple 0C4 and 0C7 - ASRA Abends, Storage Violations, and one CICS Task abended in a loss of our main production CICS Region. March 7 a secnd wave of application changes were deployed. All Of the Abends with the Exception of The Storage Vioation seem to have evaporated, as they no-longer exists. However we are now see a sihnificant Increase of I/O, Almost double in CPU consumption by many tasks, and an Increase in Storage Occupancy for these transaction. Some Transaction Storage incresaed by 6+ Meg. Working with our Capacity Planning and Performance person and reviewing CMF data, RMF Reports, running Traces, and real time Monitors we have identified the 7 buggest cuprits. (STROBE is a Great Product) . We provided our findings and analysis to our Management and Mainframe development management with much reluctance. . . Heres what I dont understand Our development management are telling is (Systems & Operations) that it is "cheaper to Upgrade the mainfame than to have the application programmers review their code for performance oppurtunities". . . Are You F...ing kidding me. . . In todays era is this true, because I havent heard of it ? . The Systems teams spent three weeks trying to compensate and adjust our performance configuration (LPAR Weights, CICS File Adjustments etc.) to accomodate the additional CPU that was introduced. . I have not seen any documents produced stating that it would be cheaper to Upgrade to a larger machine. What about the License costs for all our products ? . . If a Machine costs 8 Million, are you telling me 10 good COBOL CICS & MQ appliaction programmers could not make some improvement for less than 8-Mil ? . One of My application developers explained to me that they were getting a ASRA/0C4 Abend. So to correct it they increased 3 tables from 33 entries (3Meg) to 99 entries (9Meg). . Did I miss a performance lecture at SHARE ? . Can someone explain and rationalize for this new paradyne ? . "cheaper to Upgrade the mainfame than to have the application programmers review their code for performance oppurtunities". . Im clueless . ?? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
