Re: Any details on this migration
We run both CA-Datacom and DB2; my perception (not yet backed up by figures) is that Datacom is considerably less resource-intensive than DB2. One thing I hope to do this year is to figure out a way to compare their performance. First I need to make sure they are reasonably well-tuned, though, and then I need to try to determine what sort of differences there are in resource chargeback. Jon snip The conversion was from CA-IDEAL to Micro Focus Cobol and the migration of CA-DATACOM to Oracle. http://www.move2open.com/m2o-bupa-success-story.html Given that CA-DATACOM is a '4gl' database, I would suspect that it might not scale well and may have been slurping a lot of horsepower. And, given CA's historic pricing postures. /snip -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: Any details on this migration
Actually, let me rephrase that statement: Datacom seems to be less resource-intensive than DB2 *given the operating parameters and the workloads at this shop*. There are so many differences between the way we use them that may make a meaningful comparison all but impossible.

Of course both teams of conslutants are biding to help us re-write and migrate. Some of our board members have the idea that mainframe = expesnive and open systems (Intel) = cheap. They have all had project to migrate some of their applicatons off of mainframe, but they all are still running all of their core applications on mainframes and their applications depend on the data that we provide them. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: Any details on this migration
well, it says a LARGE SCALE systems migration, so that probably means about 50 mips. That's what the alternative platforms consider large. - Original Message - From: John Giltner [EMAIL PROTECTED] Newsgroups: bit.listserv.ibm-main To: IBM-MAIN@BAMA.UA.EDU Sent: Wednesday, April 05, 2006 9:12 AM Subject: Any details on this migration Does anybody have any details on the size of the IBM mainframe that was replaced in this migration? http://www.itwire.com.au/content/view/3825/49/ -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: Any details on this migration
A little googleing turned up that they went live in January 2005. http://www.move2open.com/m2o-bupa-case-study.pdf At that time, they were looking at a 3 year payback at $2 million per year savings. I guess the project was $6m. Wonder how they are doing?

My shop has decided to migrate most of our applications off of CICS/DB2/IDMS on z/OS. They want to go Linux on Intel running J2EE (Websphere for now) for online and trying to keep Cobol for batch with DB2 with the possibility of replacing DB2 to Oracle) as the DBMS. The applications we are migrating account for about 85-90% of our CPU usage. Our director point to this as see it's possible to migrate a large scale applications off of a IBM mainframe and save money. We are running a 1C7 and 1C3 now and will be upgrading to 304/303 in the next two weeks. In the new world they plan on use blade servers. Two four ways as DB servers and 8 two-ways for application servers (4 for Webshpere and four for batch jobs). -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
