Hi I had to upgrade one of the 8 Node RAC environment and it is running 5 Database with ASM and RDBMS with it own Home in on AIX. We have only 2-3 hrs window and so want to have expert opinion on the following 1. If I will upgrade CRS and it suggest at the end of successfull install to run root102.sh on all NODES Can I run on all node in parallel. It takes 10-15 minutes and so want to save some time. Not clear if it affect each other as anyway CRS is down at that time on that node 2. Can I run the CRS upgrade indiviual on all node at the same time from few new putty session instead of initiating from one window and selecting all nodes. The reason is that it will take 15 Minutes to upgrade on Node 1 and then 15 minutes to copy to other nodes. If there are 7 more nodes, then it will take 15*7=100+ min. to copy to other nodes. So I f will run seperately from each nodes, it will be total of 15-20 minutes for Software and then 15 minutes for root102.sh. 3. If CRS is upgraded and is down, Can I start the ASM and RDBMS upgrade at the same time or it will conflict due to /tmp/installer Lock files or any other issue can come. TIA Sanjay
