Oracle Data Pump and BFILEs

BFILEs or external LOBs allow you to store data outside the database. The data is stored in the operating system. What exactly is a BFILE and what do you need to be aware of when you want to export the data?

Patching Oracle Grid Infrastructure And Oracle Data Guard

Often, when you have RAC, you also have Data Guard. What must you know when patching Grid Infrastructure when Data Guard is present? How can you apply patches to Grid Infrastructure and the database when Data Guard is present? This blog post answers these questions.

Pro Tips

While writing the blog post series I lot of nuggets came up. I gathered the best pro tips in this blog post.

New Webinars Coming Up

Dates are settled for the next two webinars. Sign up now to get the latest updates on Data Pump and Release and Patching Strategy for Oracle Database 23c.

Oracle CloudWorld 2022 On-Demand

Get the very last out of Oracle CloudWorld 2022 by watching some of the recordings. You can find some really great sessions available on demand. All available for free on YouTube.

Can I Run Datapatch When Users Are Connected

To complete a patch apply you must execute datapatch. You can execute datapatch on a running database with users connected. But beware of the pitfalls.

Upgrade, Data Guard, and Restore Points

When you upgrade your Oracle Database, Flashback Database is an excellent fallback mechanism. It works fine in a Data Guard configuration as longs as you follow the right procedure.

How To Upgrade Data Guard – MAA Method

It is not that complicated to upgrade your database, even if it is part of a Data Guard setup. Using AutoUpgrade is fully supported and highly recommended. A little extra legwork is needed to take care of the standby database. But the good thing is that your Data Guard setup is maintained throughout the process.

Downgrade and Data Guard

If you experience problems with a new release of Oracle Database after go-live – downgrade might be the answer. Data Guard and downgrade works fine together if you follow the right procedure. Here’s how to do it.

Flashback and Data Guard

If you need to fallback a failed upgrade, you can use Flashback Database. You can even do it without compromising your Data Guard if you follow the procedure.

Upgrade and Data Guard

You can upgrade your Oracle Database to a new release and keep the Data Guard setup intact. There is no need to rebuild the standby database after the upgrade.

Why Does It Take so Long to Import Check Constraints?

When Data Pump creates constraints during import, they will be created in the same way as they were exported. Validated constraints must be validated again which can take quite some time.

XTTS: Prerequisites

The easiest way to migrate with XTTS is to use version 4 of the Perl script and Full Transportable Export Import. Can you meet the requirements?

XTTS: Pro Tips

A collection of nuggets that I gathered while writing the blog post series on XTTS.

XTTS: Make It Fast

To make your migration with transportable tablespace faster, there are a few knobs you can turn.

XTTS: Bigfile Tablespaces

Bigfile tablespaces are often used in very large databases. Do they have an impact on your migration with transportable tablespaces and incremental backups?

XTTS: Backup on Standby Database

Offload the backups from the primary database when doing cross platform migrations with transportable tablespaces and incremental backups.

Get Started with Autoupgrade

Get started with AutoUpgrade and learn how to use our Hands-On Lab to sharpen your skills.

Oracle Database 21c Is Here

Oracle Database 21c is now available on more platforms. Here’s my take on it.

Upgrade with Less Downtime

If your database is sensitive to downtime, you can use the fast deploy mode to run some tasks while the database is still online.

DataPump Export from Data Guard

To save resources on your primary database when doing Data Pump exports and to avoid ORA-01555, you can use a snapshot standby database.

Future-proof Your Encrypted Database During Upgrade

When you upgrade an encrypted database to Oracle Database 19c you configure AutoUpgrade to change the keystore definition from sqlnet.ora to the new recommended parameter – WALLET_ROOT.

AutoUpgrade One-liner

You can specify all input to AutoUpgrade in a single command – without using a config file. Ideal for scripting and automation.

How to Upgrade a Single PDB

You can use AutoUpgrade to perform unplug-plug upgrade of your PDB. It is faster, but there are some things you must be aware of.

New Version of AutoUpgrade

A new of AutoUpgrade is out and it contains several cool features like unplug/plug upgrade and better handling of data guard.

Is AutoUpgrade resumable?

Yes, it is. You can resume a terminated or lost session. AutoUpgrade will automatically pick up from where it left.

Move to the Cloud – Webinar

Get the slides from the webinar “Move to the Cloud – not only for techies”. Also, you can find the missing part on transportable tablespaces, and information about a recording.

Migration Strategies

We did a webinar today on Migration Strategies – Tips and Tricks and Insights and Secrets. Here is a wrap-up and link to the slides.

Debut on the Big Stage

In mid-October you can join our two webinars on database migration. One of them is exclusively about cloud migration – for techies only.

TDE from a Non-Security Guy

TDE Tablespace Encryption is a must-have in the cloud and something that most of us have to learn. I recently gave a presentation on the basics and what you will need to learn to survive in the cloud.
