From my mailbag: Dear nixCraft, I run a Debian Linux 8.x on my Desktop and Ubuntu Linux 16.04 LTS on my Linode cloud server for my personal website.
Earlier this week (10-April), I had done a Switchover from the 2node RAC database to a SingleInstance database.
Yesterday, I demonstrated a DataGuard Switchover from a 2node RAC(ASM) database to a SingleInstance(FileSystem) Database.
Continuing the series of posts on the RAC/ASM to SingleInstance/FileSystem DataGuard configuration … With both instances RAC1 and RAC2 running, I have redo shipping from both instances to the single instance STBY.(In my test server with 3 VMs, it takes a number of minutes to have all 3 instances running and communicating with each other … so there are spurious ORA and TNS errors until the 3 instances have stabilized.
