Developers esp database in our agency balk at any downtime during the day and any other changes. You could argue a failure of leadership in upper management but OTOH they are paid whether its up or not so we don't want downtime. Cluster also gives forced conformity. Yes you can go around updating systems and OpsCenter 11g is great and you could use Live Upgrade but that is another leadership failure partly offset by the point that the development aren't all on same revision of OS etc and so are afraid that since noone else was the guinea pig it will break their database (even Oracle dbms because they might even be as recent as 10g but still have 9i running).
Real life in an institution suffering a long period of this sort of thing is messy. ----- Original Message ----- From: [email protected] <[email protected]> To: [email protected] <[email protected]> Sent: Wed May 18 12:30:38 2011 Subject: Re: [ldoms-discuss] Veritas for development DB why need cluster at all? just use SAN to snapshot lun and move between hosts, the key is use Virtual IP (not phys-IP addess) so one can move the application very easily between hosts (after you move the storage) On 5/18/2011 12:18 PM, Hung-ShengTsao (Lao Tsao) Ph.D. wrote: > > > On 5/18/2011 12:13 PM, Hudes, Dana wrote: >> Because RAC is for parallel database clusters and that is a separate >> project by someone else who has to deal a DBA who won't let him use >> any zones or LDOMs or zfs even for boot of the platform.
