Is your PDB state saved?

Is your PDB state saved?

This might save you a couple of minutes if you wonder how multitenant works in combination with Oracle Data Guard. The question I got was, is your PDB state saved after a switchover? The short answer is: Yes it is. No statements without proving them of course, so here we go. The primary database: I have the state of my pub always saved in my post creation script, but you can easily retrieve in what state the PDB will be…

Data Guard made easy

Data Guard made easy

Sometimes I hear stories about struggles to setup Data Guard correctly. It should not be hard. There are lots of ways which lead to a correct setup. Die hards prefer the manual or own scripted way.

oops, sorry I dropped the wrong directory

There are some days, that you play around in your lab and end up with a situation you hope will never happen in real life. Today was one of those days. While playing around with 12.2 pdb’s I found following scenario. Imagine a container database in noarchivelog. I would not recommend to run in noarchivelog, but sometimes, it still happens. At a certain moment in time, you play around with the db_create_file_dest parameter and you decide to set it to /u03…
