Honored to be #1 in DB2Night Show’s top 20 DB2 LUW Shows

It’s been a while that I blogged on db2talk. We recently had an exciting addition to our family in the form of a baby girl. As a dutiful dad, I was busy changing diapers, feeding her and bonding with her. đŸ™‚

Scott Hayes’, the founder of DBI Software and the host of DB2Night Show recently tweeted top 20 DB2 LUW shows on DB2Night Show. After re-tweeting his tweet, I looked at who were in the top 20. It was a pleasant surprise!

I was #1. whooo.hooo.. I want to take a moment and thank Scott Hayes for hosting a platform to share my DB2 knowledge and for DB2 DBAs all around the world for tuning into this show and for downloading replays. I am honored and humbled to be among DB2 stars like Scott Hayes, Ember Crooks, Matt Huras, Iqbal Goralwalla, Melanie Stopfer, John Hornibrook and many others.

Here is the link to the actual article on DBI Software’s site.

DB2 LUW Database Object’s owner and Instance Owner’s authority over it

Here is an interesting challenge I faced recently. I was going to replace (rebuild) a view with new DDL and I got error code SQL0551N which meant I didn’t have authorization to do so.

How to bring tablespace state to offline

I learned something interesting recently and I wanted to share in this blog post.

In this blog post, I will share how to bring a tablespace’s state to offline. Please know that doing so will put all the tables in such tablespace in inaccessible state. This could result in an outage situation. I have only used this approach for testing monitoring setup. You are cautioned from using this. Continue reading
