Customer is running 10.2.0.2 RAC on Solaris 10. Final objective is to upgrade to RAC 10.2.0.4. Requirement is as below; 1) Upgrade Solaris 10 patches from Generic_118833-03 to 142909-17 2) Upgrade RAC to 10.2.0.4 Question1: Customer is thinking of performing the OS patch upgrade via the below strategy; Night1: 1. Shutdown node2. 2. Shutdown crs/db on node1. 3. Perform OS upgrade on node1. 4. Once node1 successfully upgrade it’s OS, start crs/db on node1 and continue database operation until night2. Take note that node2 is down from night1 until night2. Night2: 1. Shutdown node1. 2. Startup node2; do not startup node2 crs/db. 3. Perform OS upgrade of node2. 4. Once node2 successfully upgrade it’s OS, startup crs/db on node2. 5. Now startup node1 and it’s crs/db and join cluster Now both node crs/db continues operation. Is there any concern on the OS patch upgrade strategy as above? A: No issue on the OS patch upgarde. Stay within a 24 hours of upgrade window. Question2: After the OS patch upgrade via the strategy above, is there a need to do anything on rac (db/crs)? Perhaps relink? Or do we just bring up crs and both crs/db will up and running? A: Doc ID 444595.1 - Is It Necessary To Relink Oracle Following OS Upgrade? Question3: We notice that SUNWsprox OS package is not available in both servers. However RAC is already up and running. Does it mean that SUNWsprox package is not needed in SOlaris 10? A: That OS-Package SUNWsprox is not required at Solaris 10 (see note 169706.1). Therefore this error can be ignored on your OS version. Question4: Customer would like to disable gsd. Is this recommended? A: Yes you can disable the gsd. Question5: During the OS patch upgrade, java version will be upgraded from "1.5.0_06" to "1.5.0_24". Will there be any issue with RAC? A: No issue with RAC. Question6: If OS patch in node1 is upgraded but not on node2, will RAC have any issue? A: Please refer the below doc, Doc ID 220970.1 - RAC: Frequently Asked Questions
