-----Original Message----- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of Tom Duerbusch Sent: Friday, November 21, 2008 3:35 PM To: [email protected] Subject: Re: Oracle DB's and Why?? We are running Oracle 10g R2 on our z/890 with an IFL. The reason....pure and simple...cost. I'm currently running 6 Oracle images (i.e. 6 Linux guests, SUSE 10 SP2) on the IFL. Cost of Oracle license, $44,000 (single engine). To run these 6 images, each on their own server, 6 * $44,000 for Oracle licenses (single engine on each server). These are not real heavy hitters, Oracle images seems to be taking about 10% of the IFL. Each of the images takes 600 MB virtual, with a few vdisks for paging. The Oracle SGA was also trimmed down greatly. I let the ficon attached DS6800 handle the I/O load. When I'm shown that response time becomes a problem, I will then up the Oracle SGA, and the Linux guest size for more cache hits, but until then.... We do have 4 Oracle licenses for WINTEL. The few people that access Oracle on both platforms can't tell, from a performance perspective, that they are on the mainframe. With the success, management has made a goal, not to buy/install any databases on any other platform other than the mainframe. (I doubt that we will have 100% compliance.) We have changed requirements that specified SQL/SERVER to Oracle, with pretty good luck. Some also go to DB2/VSE and eventually DB2/UDB (on the mainframe). Other considerations: 1. Security. 2. Virus concerns. 3. Backup. 4. Disaster recovery. 5. Ability to serve the data to any authorized dept/agency/division. 6. Reduction of replacement of current database servers. There were 9 items. I can't think of the other 3. Must be getting beer time <G>.

Were the AIX or Wintel platforms considered?? Thanks, Chris IMPORTANT: This e-mail and any attachments may contain confidential, proprietary, and/or privileged information.
