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. 🙂

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 could this happen? I was using instance owner’s user id (db2inst1) which meant I should be able to drop and/or re-create database objects.. right?

Using awk to format output from select statement in DB2 on AIX/Linux

In this blog post, I will share with you a simple way but effective way to format the output from a select statement at the command prompt.

The 2016 IDUG DB2 North American Tech Conference – May 23 – 26, Austin, TX.

“It ‘s a very exciting time” — The Matrix (1999) 00:47:48

Indeed it is! The biggest conference on DB2 is right around the corner. Less than a week to be precise.

This years conference is special to me because this not only my 3rd consecutive IDUG but also my first time as an IDUG core member in Conference Planning Committee. As a core member of CPC, I participated in conference’s agenda being built, saw rooms being assigned to sessions, voted on abstracts, stayed in touch with all the speakers in my track (DB2 LUW Track – II) to get their draft and final copies uploaded and lots of other activities. I am eager to see the effort of so many people come to fruition. I now have lot of appreciation to what goes behind the scenes of a great conference with utmost quality to happen without minimum hiccups.

I am also eager to meet my DB2 friends and learn from the best DB2 minds in the industry. If you have not attended IDUG before or not sure if you want to attend this time, I would highly encourage you consider to attend this one.

How to bring tablespace state to offline

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

Recently, I was working with our enterprise monitoring team to setup monitoring/alerting for distributed DB2 databases. One of the alerts we wanted to setup was when a tablespace state is OFFLINE.
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.

Calculating size of table in a DPF database

Starting from DB2 versions 9.5 and up, a rich and detailed DB2 administrative view called SYSIBMADM.ADMINTABINFO comes bundled with DB2 engine. Among many things, it provides a handy way to calculate table size. In this blog post, we will look at how to calculate table size in a DPF database.

DB2 LUW Import from /dev/null, Restore and Rollforward

In an earlier blog post, we looked at recovering data after ‘TRUNCATE’ operation.
In this blog post, we will look at recovering data after using ‘import’ command to quickly get rid of data.

DB2 LUW Truncate, Restore and Rollforward

Starting in DB2 LUW version 9, TRUNCATE is supported. This gave ability to quickly get rid of massive amounts of data from tables without worrying about possibility of filling up logs. But, one question that seems to linger around in the minds of many DB2 LUW DBAs is “Is TRUNCATE operation recoverable?” I set out to find this out myself recently. This blog post details such findings.

2015’s Highlights and Happy New Year 2016!

I hope everyone has had a great start to the 2016 year!  I wanted to take a moment to express my gratitude for being a db2talk visitor and reader.

Just a couple of 2015’s db2talk highlights that I would like to share:

1. In 2015, the number of views and unique visitors on db2talk almost quadrupled compared to 2014.
2. DB2 Basics and DB2 Tips are two most popular categories.
3. Blog posts related to awk and UNIX tips and tricks have been very popular in terms of blog-post hits.

DB2 Sample Database – Modifying storage path

In an earlier blog post, we looked at how to create a sample database in DB2 LUW. We also looked at changing the defaults to suit our needs…changed the default database name from SAMPLE to whatever we wanted and also changed the database path (DBPATH).

Here is the link to that blog post: http://db2talk.com/2015/09/08/creating-a-db2-luw-linux-unix-and-windows-sandbox-database/
