system/r ... san jose research, bldg. 28. work was for vm/cms on the group's 370/145. there was then technology transfer to endicott for sql/ds product for vm, vs1 & dos/vs. some past posts about system/r http://www.garlic.com/~lynn/submain.html#systemr when "eagle" effort "crashed" in STL, the system/r group was asked how fast they could turn out something for MVS. System/R reunion discussion of SQL/DS mentions that massive EAGLE project in STL kept attention away from RDBMS ... allowing System/R to get out as SQL/DS http://www.mcjones.org/System_R/SQL_Reunion_95/sqlr95-SQL_DS.html quote from above: The surprise of the MVS project was that it happened faster than I thought it would. In other words, Plan A collapsed, all right? Eagle collapsed, and all of a sudden, everyone turned to us and said, "OK, when can you ship this database product?" [laughter] And that's when we had to make some fairly hasty, difficult decisions on ... ... snip ... lots more in the System/R 1995 reunion http://www.mcjones.org/System_R some mention in Jim's departing "MIP Envy": http://www.garlic.com/~lynn/2007d.html#email800920 slightly later 24sep80 version here: http://research.microsoft.com/~gray/papers/CritiqueOfIBM%27sCSResearch.doc Oracle executive mentioned in this Jan1992 meeting claimed (when he was at STL) to have handled the SQL/DS tech. transfer from Endicott back to STL for DB2 http://www.garlic.com/~lynn/95.html#13 past posts about Jim palming off bunch of stuff on me when he was departing for Tandem ... including consulting with the IMS group and customers running System/R http://www.garlic.com/~lynn/2007.html#email801006 http://www.garlic.com/~lynn/2007.html#email801016 some also discussed at celebration held for Jim at Berkeley http://www.garlic.com/~lynn/2008i.html#32 A Tribute to Jim Gray: Sometimes Nice Guys Do Finish First audio from the celebration http://www.garlic.com/~lynn/2008i.html#50 Microsoft versus Digital Equipment Corporation sql/ds mentioned here ... http://en.wikipedia.org/wiki/IBM_SQL/DS sql/ds redbook http://www.redbooks.ibm.com/abstracts/gg244047.html and sql/ds "rebranded" here http://www-01.ibm.com/software/data/db2/vse-vm/ as referenced above ... the "official" DBMS effort in STL was called "EAGLE", but when that crashed ... then the system/r group was asked how fast could a RDBMS be turned out for MVS. recent post/mention in (linkedin) Greater IBM http://www.garlic.com/~lynn/2011d.html#42 Mainframe Hall of Frame. List of influential mainframers thoughout history as an aside ... the first commercial offering of Codd's relational (worked at research in bldg. 28) http://en.wikipedia.org/wiki/Edgar_F._Codd was on Multics http://en.wikipedia.org/wiki/Multics_Relational_Data_Store more on MRDS from the System/R reunion: http://www.mcjones.org/System_R/mrds.html RDBMS wiki page http://en.wikipedia.org/wiki/Relational_database_management_system trivia ... multics was on 5th flr of 545 tech sq. The science center that did virtual machines, cp67/cms, etc ... was on 4th flr of 545 tech sq. When the cp67 group split off from the science center, they took over the Boston Programming Center on the 3rd flr (morphing into the vm370 development group). The development group outgrew the space on the 3rd flr and moved out to the old SBC bldg. (vacated in the legal actions where IBM transferred SBC to CDC) in Burlington Mall. misc. past posts mentioning 545 tech. sq http://www.garlic.com/~lynn/subtopic.html#545tech in the wake of demise of Future System project ... misc. past posts http://www.garlic.com/~lynn/submain.html#futuresys there was mad rush to get products back into the 370 (hardware & software) product pipeline ... having been killed off during the FS period. Part of that was the head of POK managed to convince the corporation to kill-off VM370 Burlington Mall development group, becuase he needed to transfer all the people to POK for MVS/XA development (or otherwise he couldn't meet the ship schedule). Endicott managed to save the vm370 product mission, but had to recreate a development group from scratch. -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- 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
