Hi,

I have to apply a bugfix patch in RAC environment. I go through readme file and according to my understanding i have to follow the below steps:

1. Shutdown instance on both nodes

2. upload the p5606847_10203_Solaris86-64.zip file on server and unzip

3. cd 5606847 

4. opatch apply 

I have the below queries:

1. Do i need to stop all the oracle services on both nodes ? or shutdown instances is enogh.

2. Whether the patch will automatically apply on both nodes or we need to patch individually all the nodes ? if yes, then any difference in the above steps.

Please provide your inputs.

Thanks
Harsh

It actually depends on the options you choose (like rolling upgrades). As Michell already said, just look into readme file and do as it says.

All what is needed to be stopped is mentioned in the readme files. If something is not mentioned then it is not mandatory to stop it.

Michel

Don't hijack a topic with a subject that doesn't have any relation with the previous question, create your own one.
Documentation is on http://tahiti.oracle.com

I will recommend u stop all oracle processes in both nodes before applying the patch.
Also make sure ssh is properly configured to assure propee communication b/w all nodes before patching.
However, do not stop the crs...

Take care...

when we apply patch we are touching the binaries of oracle.

Readme doc which is been provided by oracle have all the steps, every patch has its own step but while CPU patch,

use the correct opatch utility
set the opatch path if required.
.

Stop listener
stop instance
stop agent

put the db instance in blackout if you using grid, so that no alert should be generated

Take proper down time for applying patch.

It means Before doing opatch apply

Note :- By which command we have to give for applying patch is there in readme.txt

once patch is applied successfully please run the catcpu.sql if u applying cpu patch... and also ultrp.sql after starting the DB than start the listener.

We can apply patch simultaneously on both the node on rac but its always good to apply patch on one node so that if any error comes our one instance is up and running, business will not be impacted.
