Rolling Upgrades in Rac
728006May 20 2010 — edited May 21 2010Hi All,
can you please explain abt rolling upgrades in rac env
suppose i am having rac setup on 10.2.0.1 if i want to apply patch set 10.2.0.4 is it required downtime
As per the readme of 10.2.0.4
1)Stop every thing on node 1 and apply patch set
2)stop every thing on node 2 and apply patch set
3)stop the database and run the catupgrd.sql script.
My question is for running catupgrd script i have to bring down the db so what the meaning of rolling upgrade??
And in this type of sece which type of upgrade is best one rolling or non-rolling.
KK
