According to Metalink Note 161818.1 Oracle Server (RDBMS) Releases Support Status Summary, Premier Support of Oracle 10g Release 1 ends in January 2009, which means that those of us supporting Oracle 10.1 databases have less support from Oracle from now on.
During the Premier Support time-frame, Oracle is committed to providing interim patches for the most current patchset (and if you can persuade them, even for older patchsets). Oracle 10.1 is only supported as part of Extended Support, a purchasable option providing customers with an option to get one-off patches for their critical issues.
You are still able to log a Service Request against Oracle 10.1 release, and Oracle might even be able to open new bugs and suggest workarounds—but don’t expect much enthusiasm from Oracle Support. The good news is, if you are still on 10.1, you can and should use this as a weapon in your arsenal to argue for an upgrade to 10g Release 2 or even 11g.
We still have few 10.1 databases amongst our 100+ clients (granted, only few), and this helps to make the decision. Unfortunately, the current state of economy doesn’t help to push an upgrade project; but <shameless_plug> you know where to got to get cost effective help with Oracle 10g and 11g upgrades. Don’t you?;)</shameless_plug>
At the moment, my team is upgrading two clients from 10.1 (one RAC and one cold failover on a Solaris Cluster). What’s the state on your side? Any 10.1’s still kicking around? Is management receptive to the upgrade ideas? Speak up!
