From: Dolphin on 18 Feb 2010 08:51 Hi, We have a Solaris 10 V490 server installed 2 years ago and did not apply any kernel patch or cluster patch as no down time granted. Now the application wanted to have it patch to the latest level. Can I down load the latest cluster patch and apply it to the system? If not, how should I go about it? I have a Solaris 10 DVD 10/09 release, can I use it to upgrade the system instead of applying the latest cluster patch? Thanks in advance.

As of about a week ago you need a paid support contract before you can download *any* patches. This situation may (or may not!) change, so keep watching sunsolve.sun.com. > I have a Solaris 10 DVD 10/09 release, can I use it to upgrade the > system instead of applying the latest cluster patch? You could also try a Live Upgrade, but that does require that you partitioned your boot disk before doing the original install - the upgrade works on the 'other' partition. -- Chris

It's usually best to install patches but, unless you have an immediate problem it's best to wait a while. Patches, in particular, are risky. They attempt to fix a problem or problems and therein lie the seeds of a new problem. The fix was written "under the gun" and the testing was also done "under the gun"! A patch almost always fixes the original problem but there is a significant risk of introducing a new problem, or problems. Many shops will run an upgrade/fix candidate on a test system for some period before moving it to production. Sometimes you can't do that! You should try to have a "back out plan" in case of need. |
