How to Switch from CDB to PDB: A Step-by-Step Guide

Hey buddy! So, I heard you got a little lost in the land of databases. You’re stuck with that CDB and wanna jump ship to PDB. Well, don’t worry! I got your back. Switching databases can be as easy as switching TV channels, right? Or is it more like changing a tire? Seriously tho, let’s dive into this. Grab a snack, and let’s get this party started!

Step 1: Get Your Gear Ready

Okay so first thing first, you gotta make sure you have what you need. Think of it like going on a road trip. You wouldn’t wanna forget snacks or your favorite playlist, right?

You need Oracle installed on your laptop or whatever machine you’re using. And make sure you got proper rights to access both CDB and PDB because let’s face it, nobody likes a gatecrasher.

Step 2: Make a Backup… Like A Superhero

Now that you’re ready–time for the backup part! This is like putting on a cape before saving the day. Because if something goes wrong in this switcheroo, you don’t want to be that person crying over spilled data.

So go ahead and backup your CDB. Use RMAN or any other superhero tool you have in your arsenal.

Step 3: Check the Version – Major FOMO Alert

But wait! Before jumping in headfirst, check the version of Oracle you’re running on both CDB and PDB. This is important because switching between versions can lead down the scary road of “Oops! What did I do?” Not fun at all.

Just make sure they are compatible or else it’s gonna be awkward like running into an ex on date night.

Step 4: Say Goodbye to CDB – Gently

So now you’re ready to say goodbye to your CDB like it was your boring old sweater that shrunk in the wash. Don’t burn bridges though!

To create a new PDB from the existing CDB just run some simple commands like ‘CREATE PLUGGABLE DATABASE.’ Yep! Sounds fancy but trust me, it’s easier than ordering takeout.

Step 5: Let There Be Light… Er… Connections

And now it’s time for connections! This part is kinda like making new friends at school. You gotta tell everyone who’s new in town so they can stop being shy.

You need to configure network settings for PDB so other systems can find and talk with it. Run commands like ‘ALTER SESSION’ stuff so everything gets cozy together.

Step 6: Populate Your New Hangout Spot

Alrighty! Now that your PDB is ready and chilling, time to move some data into your new digs!

This part can be done easily using data pumps which sounds cooler than it actually is by the way. Just think of them as delivery trucks bringing all your stuff over from CDB without dropping anything (hopefully).

Step 7: Test It Like You Just Got A New Toy

Finally, you’ve made the switch! Time for testing because we don’t want any surprises later on—like finding out that remote control car doesn’t actually drive straight.

Check if everything works as it should—run queries and see if your data is cozy in its new home. If everything looks good give yourself a high five!
