I want to upgrade my EBS from 188.8.131.52 to 12.1.3 (keeping DB same , i.e., 184.108.40.206). I have MT services running on 5 nodes. All 5 nodes have all the services enabled.No, you need to run it on one node after laying down the software and apply the patch using (options=nocopyportion,nogenerateportion) -- http://docs.oracle.com/cd/E18727_01/doc.121/e16342/T527285T527419.htm#upgd_perform_upgrade
My doubt is :
While applying the upgrade patches, Do I have to execute the patches on all the nodes ?
If yes, Do I have to run them sequentially (one node after another) OR can I run them parallely (simulteneously on all nodes )?
Do I have to use any special options like 'nodatabaseportion' etc ?
1. I laydown the file-system on node a, apply the upgrade patch on node a. (is there no need to lay the file-system on the remaining nodes ?)No, just lay down the software on one node.
2. I then have to clone the rest of the nodes (b,c,d) using 'node a' as source ?Correct -- Rapid Clone Documentation Resources For Release 11i and 12 [ID 799735.1]
I have another doubt : My DB is RAC enabled (say node1,2,3). I don't want to lay new filesystem for my DB as I have the desired version of it. While laying the filesystem of MT (node a), I can define only one DB node (node1),Correct.
how/where shall I define the other 2 RAC nodes (node 2, 3) ?You do not have to define them, just bring the other two nodes up (in case you shut them down before the upgrade) -- Using Oracle 11g Release 2 Real Application Clusters with Oracle E-Business Suite Release 12 [ID 823587.1]
I am follwoing the note : Interoperability Notes EBS R12 with Database 11gR2[ 1058763.1].As mentioned in the doc, if you are on Linux/Unix then you need to apply this patch.
1- Step 2: Apply patch 6400501 to the IAS 10.1.2. Do I really need to apply this patch ?( I am not sure how I can check whether this has already applied or not)
2- Step 6: Install Oracle database 11g Products from the 11g Example CDs. Do I need to do this step and please ket me know whre I can get this CD ( I have 2 files : p10404530_112030_LINUX_1of7.zip and p10404530_112030_LINUX_2of7.zip)Yes, it is mandatory and you need to download all files.
Do I need to download anything extra here to fullfil the step.
3- Step 8: Apply additional 220.127.116.11 RDBMS pathes :Before the upgrade. As mentioned under the same step "Do not run any of the post install instructions as those will be done after the upgrade.".
Before applying this additional patches, I hv to upgrade the database to 18.104.22.168. Please correct me if I am wrong.
As per the note, step 13 is to upgrade database to 22.214.171.124. I got confused here, It means, Do I need to apply additional patches on 10.2.0.5 database then upgrade to 126.96.36.199
