From JTESTA@longaberger.com Mon, 17 Sep 2001 12:33:08 -0700 From: "JOE TESTA" Date: Mon, 17 Sep 2001 12:33:08 -0700 Subject: RE: Looking for 24 X 7 Design Considerations Message-ID: MIME-Version: 1.0 Content-Type: text/plain Anyone contemplating upgrading anything more important than a sandbox database to 9i is nutso.   9i is ready for development playing around in 6-8 months, production no earlier than 12-18 months is my estimation.    joe >>> DWILLIAMS@LIFETOUCH.COM 09/17/01 03:25PM >>>Tracy - Is there any possibility of upgrading these databases to Oracle8i,or even better 9i before you implement 24X7? Oracle is claiming new featuresin 9i will support 24X7. I would also imagine that if you could bring alldatabases up to the same level, it would be easier to establish policies.For 7.3.4, you might need to do something entirely different. Also there isa book "Oracle 24x7 Tips and Techniques" by Venkat S. Devraj, but thepublishing date was 1999, so the information may be dated.Dennis WilliamsDBALifetouch, Inc.dwilliams@lifetouch.com-----Original Message-----Sent: Monday, September 17, 2001 10:15 AMTo: Multiple recipients of list ORACLE-LWe currently have 15+ databases (7.3.4 & 8i using IBM AIX and HACMP) that donot have a  24x7 restriction.  Now, management is looking to bring in newproducts that will need to be 24X7.  They are looking for costs to determinethe viability of such a decision.  I have no 24x7 experience and am lookingforideas or options to consider.  [At least initially they are stating therecanbe no downtime for maintenance (upgrades/reorgs)]-- Please see the official ORACLE-L FAQ: http://www.orafaq.com-- Author: Tracy Rahmlow  INET: Tracy.Rahmlow@aexp.comFat City Network Services    -- (858) 538-5051  FAX: (858) 538-5051San Diego, California        -- Public Internet access / Mailing Lists--------------------------------------------------------------------To REMOVE yourself from this mailing list, send an E-Mail messageto: ListGuru@fatcity.com (note EXACT spelling of 'ListGuru') and inthe message BODY, include a line containing: UNSUB ORACLE-L(or the name of mailing list you want to be removed from).  You mayalso send the HELP command for other information (like subscribing).-- Please see the official ORACLE-L FAQ: http://www.orafaq.com-- Author: DENNIS WILLIAMS  INET: DWILLIAMS@LIFETOUCH.COMFat City Network Services    -- (858) 538-5051  FAX: (858) 538-5051San Diego, California        -- Public Internet access / Mailing Lists--------------------------------------------------------------------To REMOVE yourself from this mailing list, send an E-Mail messageto: ListGuru@fatcity.com (note EXACT spelling of 'ListGuru') and inthe message BODY, include a line containing: UNSUB ORACLE-L(or the name of mailing list you want to be removed from).  You mayalso send the HELP command for other information (like subscribing).
