I have oracle database 22.214.171.124 with RAC feature , with 2 node on oracle linux 6.4 :
ol6-112-rac1 and ol6-112-rac2
I want to create active data guard with RAC feature from this database , these active dataguard with rac option has 2 node :
I want to use this document for creation active data guard from rac database to rac database :
I do the steps in this document , all of things is ok but in step " Start the Managed Recovery Process " after i want to switch log in primary , switch log is not occurred on standby database . After " tail of alert log " on standby database and executing " Switch log " on primary , this error is occurred :
