Blocking – I Saw What YOU Did and I Know Who YOU Are!

When I was growing up I remember my mom talking about an old, scary, movie that she saw when she was young. In the movie some teenagers were making prank phone calls saying “I saw what you did and I know who you are.” One of the calls happened to be made to a guy that just killed his wife. Joan Crawford played a woman that was romantically inclined to said murderer. She eventually meets her demise when he stabs her because she knew about the first murder.

How every DBA feels when there is blocking

While blocking in SQL server might not be a felony offense (it isn’t…but it should be – WHO’S WITH ME?) as the DBA you not only want to know what is being blocked, but also who is doing the blocking and what in the H-E-Double-Hockey-Sticks they are doing.

At SQL Saturday Orlando I talked about this very thing and the query I defer to for the information.

IMA GONNA HUNT U DOWN!

It might look complicated but it is actually very simple – query sys.sysprocesses with a cross apply using the sql_handle to get the text of the query, and then an outer apply with the same query again but you are joining to the blocking spid so you can get the text for the query that is doing the blocking. Beyond that, you can filter on various columns and refine your output

WHY ARE YOU BLOCKING YOURSELF? WHY ARE YOU BLOCKING YOURSELF? WHY ARE YOU BLOCKING YOURSELF?

Of course, I know you can’t run this without the code (and I know that’s why you’re here…because I SAW WHAT YOU DID!)

If you are looking for a good way to troubleshoot blocking I hope this helps. If you have some folks running queries that are making you stabby, run this, find out what is going on, and then remove their access try to help them so they aren’t making you stabby any more. Then tell them they need to buy you a beverage because they are still alive.

It’s About Time for…#SQLSatOrlando!

Next week I am returning to Orlando not only to visit the mouse at his house, but also to speak at SQL Saturday Orlando! Last year was my first time there and I had a great time. This also happened after the event was pushed back to November 2016 because of Hurricane Matthew.

This year I will talking about deadlocking and blocking – something that is an issue for so many DBAs. Whether this issue is indexes or bad code…or you have been trying in use indexes to cover up bad code, blocks and deadlocks can happen in even the best environments under the right circumstances. If you are going to be at SQL Saturday Orlando come to my session where we will talk about detecting and preventing these arch enemies of the DBA!

Wanna Get the Kids Interested in Coding? Make it a Game. Literally!

Former co-worker and friend Daniel Janik is trying do something that I will eventually have to do – get a teenager interested in something that can lead to a career.

I’ve been teaching my 17 yr old SQL Server and other various topics. I have quite a bit of experience training technology and speaking but it never fails; after about 5 minutes his eyes glaze over and he nods and “umhums” and then starts checking his phone.

I have one nephew that is already intrigued by the PowerShell that I am doing and seems to have a genuine desire to write code. This makes me SOOOOOOOO HAPPY! My hope is that he is able to continue what he is learning now and migrate into a skill set that will afford him a good career. And if he happens to maybe “hack” into something that he shouldn’t have, I will help with his bail, smother him with hugs and kisses and tell him “OMG…I AM SO PROUD OF YOU!!!”

Check out Daniel’s blog post, download the game and give it a whirl. I plan on showing my nephews this to get the opinions of the younger, not-a-teenager set. I doubt my niece will be interested in this right now…unless there was a Disney princess in there with the sea monsters. I will leave it to Daniel to incorporate that in the 2.0 version. 🙂

 

Speaking – SQL Saturday Baton Rouge!

This Saturday will mark the fourth year that I will be speaking at SQL Saturday Baton Rouge at LSU. Out of all the SQL Saturday events I have participated in since 2014, Baton Rouge is one of the few that I have been to every year since. Houston is another one…and actually, these may be the only ones only because they have had an event every year.

Not only am I speaking on Automation with PowerShell and Deadlocks and Blocking, but I am also participating in a panel discussion on Careers in IT. I’m excited to be invited along with some of the other speakers to be a part of this. Looking back on my own school days, I knew I would have a career in IT, but little did I know I would detour from a path in development to the world of SQL Server, and becoming a DBA.

How do they make this happen? Work. Lots of hard work. After helping with SQL Saturday Dallas 2015, joining the NTSSUG board in 2016, and then having an organizing role in 2016, I found out how much goes into the planning of these events. If you have attended a SQL Saturday or you are going to in the future, be sure to say “THANK YOU!” to all the organizers and sponsors. If you want to get more involved in the SQL Server community, SQL Saturday is a great way to do that – just show up at the event, find an organizer and tell them that the SQL Kitten sent you to be their humble servant volunteer for the day…or you could just say you want to volunteer and leave out the other stuff because it might make it weird.

Podcast with SQL Data Partners

Recently I had the pleasure of meeting Carlos Chacon with SQL Data Partners and found out he had a podcast (I know…I live under a rock…with cats). He asked if I was interested in being on said podcast – ummmm…yes, please! Click here (Episode 33) if you wanna go listen to the podcast or here if they get all up in your grill about streaming stuff at the office and you wanna just read the transcript. Thanks to Carlos for the opportunity! Enjoy! 🙂

T-SQL Tuesday #73 – Those Darn Elves

t-sqltuesdaySince I have not blogged in a while, and I saw it was T-SQL Tuesday, I thought I would participate in this FOR THE FIRST TIME EVER! This month SQLBalls asks us if our SQL Servers are on the naughty or nice list. Since I have recently transitioned to a new role, I am still getting familiar with the servers and the environments I am working with. The servers of my past are but a memory, but a fresh one. I cannot even begin to think of all the different “naughty” things that were done on those servers, and how some days it felt like a losing battle. How can you fight a security or code change when you have been over ridden by management, only to have that change come back and bite you weeks or months later? The “I told you so” you might feel like popping off will fall on deaf ears and you will just be stuck fixing the problem…until it gets to be too much and you decide it is time for action.

I have done this before. The day had been a long one and I thought I was finally going home when I got drug into a call on a data issue – something was changed that shouldn’t have been. When and by whom? I didn’t know or have any way of finding this information (days later when I tried to get a backup that was several months old to validate this data from when it was deployed; there was no backup – all all – but that is a completely different issue for another time). I had my suspicions but no proof. Could have been a naughty developer elf logging in with an elevated SQL account they knew the password for. Changing the password? “Out of the question” they say. It is everywhere.

If this were the only event that had happened THAT DAY. It wasn’t. This one was production (hence the conference call). The others (yes, more than one) were pre-production. Messes that had to be cleaned up because the developer elves thought they knew better than the DBA and that they could do it on their own. This production issue was the last straw. Elves were running a muck and had to be reigned in, and they weren’t going to like it.

All the elevated permissions in the pre-production servers – gone. I didn’t care if it was a DEV server. Am I the meanest DBA in the world? So says some. Scrooge? Well, if you are into name calling and want to go there, then ok, but I get to call you names too. In this case I did not care – I was fixing things that were only broken because someone abused a privilege. It should also be said that there was some relation in the names off all the tables involved with all the issues that occurred on this day.

If I had to wag my finger and any naughty part of the SQL Server instances it would have to be at security…and I am partially to blame. It can be difficult to keep up with all the changes that happen across a large environment when it comes to assigning permissions, and if you have more than one DBA, the situation is compounded by the fact that you might not always know what the other is doing and vice versa. They might grant something that you would otherwise veto for cause. You might take care of a permissions issue one way when they would handle it differently.

While I worked on some Powershell code to pull back users from specific AD groups and incorporate alerts for some of those groups, sadly the bandwidth was not there to fully roll this out. I did however create some triggers that would send email alerts when a change was made at the server and database levels, and I made them nameless and encrypted.

 

 

The lack of a name for each of these is intentional, as is the encryption. The last thing I wanted was someone seeing these ans what they were doing, and if they had permissions to do so, disabling or dropping them to avoid having their nefarious behavior tracked. Even better would have been to put additional triggers in place to prevent the dropping of these no matter what, but I decided not to go there.

Note there is nothing there for the name for each of these – this is courtesy of the devious mind of Rob Volk. He might have too much time on his hands but this is pretty darn crafty. What you name these triggers is up to you but you have to MAKE NOTE OF WHAT THE NAME ARE!!! When I did these they were a combination of a few tabs and spaces – like “space space space tab tab” but with those actual characters. The result looks like this:

 

triggers_noname

It should go without saying use this code at your own risk and always thoroughly vet and test anything before applying it to a production environment.

If this helps further cement my meanest DBA creds then I guess I am doing it right. Sometimes the elves developers can get out of hand and it is up to Santa the DBA to make sure they know they are being watched.

 

My First Time Submitting to SQL PASS Summit – Part 1

I have now officially submitted to SQL PASS Summit 2015. Five sessions. All me (well, and a few others on the panel I submitted). The hard part is over…but how did this all happen?

My story starts back in the year 2013. My first time to attend a SQL PASS Summit. It was in Charlotte, NC. I didn’t know these were normally in Seattle. It didn’t really seem to matter too much either. I was a first timer. And they labeled me as such.

first_timer_2013

I didn’t mind. I knew I was a newb. I embraced it. I signed up for and watched the webinar for first timers put on by Denny Cherry. I also got a first timer buddy (aka Someone I can follow around like a puppy until I am comfortable enough and have found other suitable, like minded, people that will welcome me and allow me to accompany them to places that sell beer).

I met so many new people while at Summit that year and out of all the conferences I had been to in the past, this was by far the best experience I had ever had. One this that happened numerous times when talking to people was hearing the words “Have you thought about presenting?” I’m all “Wow…these people are nice…and encouraging…wait…presenting? Say what?”

Did they need fresh meat? A new crop of willing yet unsuspecting folks to throw their hat in the ring, to hopefully be selected, and dive head first off that cliff into something that might become an obsession that would challenge them in ways they had never thought of before? Maybe. Maybe they did. Maybe it was a little cultish. Well, pass the kool-aid.

I came home and gave it some thought. I really wanted to do this but did not know where to start. I felt like I had stuff to say. Stories to tell. Experiences to share. But where to start? I decided I would do a panel. I rounded up some experienced speakers for a particular SQL Saturday, created my session and submitted it. That was the easy part. I then decided we would have weekly internet video chats so that everyone could get acquainted, and I could get their take on how they saw the panel going. They were also able to provide me much needed guidance with my slide deck (something else I had never done before) and how the session needed structure. I took all this in and did my slides accordingly.

The time finally came for the SQL Saturday event and my panel session. I made the trip out there and met up with everyone. I attended my very first speaker dinner. I could not believe I was there and in the same room with some of the brightest and well known minds in the SQL community. This was it – my first taste of what would consume that entire year.

The panel went well. My fellow panelists and other patted me on the back for a job well done. Feedback was good. I was elated. I was hooked. I thought I was ready to handle what was up next – my first solo session. Just me and my slides. Another SQL Saturday. Another city.

Code Upload – Pragmatic Works webinar

For those that attended my webinar last week with Pragmatic Works I have uploaded the code…finally. For what it is worth, the weekend was busy and I was working on my SQL PASS Summit submissions. Then, just as I was getting this together on Monday night, I was not feeling right and realized I was making mistakes and that is no good. Tried to go to work on Tuesday but even they knew something was wrong with me. Went home and found out later my nephew was also sick. No need for any further details. Just trying to get better. Thanks for your patience. 🙂

 

The lovely people at Pragmatic Works sent me some of your questions from the webinar. Without further adieu…

Do you have a suggestion for BEGINNERS learning books to get a basic understanding of PS??

Great question! While I have a TON of books on all kinds of things (SQL Server, C#, web dev stuff, etc.) I do not have a single book on Powershell. How did I accomplish all this then? Simple – using this pesky thing we call the internet. I have also attended some great Powershell sessions at SQL Saturday events.

Did they leave any beer bottles?

The roofers? Thankfully no.

Do not criticize the king of soda pop, Dr. Pepper!

Preach it!

When will VBScript stop functioning for SQL Server or Windows Server. As in will there be a total switch?

VBScript? Hmmmm…great question. No clue. This might be a Microsoft cockroach. Like replication.

why we need a PS-Drive – why we can just use an arraay directly?

You mean passing in the server name from the array to the Invoke-SqlCmd? Yeah, you could do that. That’s just not how I wrote this. 🙂

what is her email again?

Leave a comment here if you would like to email me and I will get back to you.

does the ( $servers | Measure-Object).count syntax do?

That counts the number of items in the array.

What is the purpose of the New-PSDrive?

New-PSDrive is a method of connecting to a SQL Server instance. Another method would be to declare a connection with SMO (Server Management Objects).

Does it work on windows 2003 as well?

I have not tested this against Windows Server 2003.

so, ps-drive is the equivalent of object explorer in SSMS?

Well, kinda. Maybe. More the equivalent of browsing a drive in a cmd.exe window.

what city in Austin?

Ummmm….Austin is a city.

What permission you require on AD for this excercise

To make the AD changes, I have no clue. Not my area and I also intentionally created the Azure VM so I could make all the changes I needed to without worrying about a silly thing like permissions. As far as reading from AD (which is the main Powershell script for this part) I am not sure about this either but I am assuming you need some level of read permissions (which is all that script is doing).

There are some things where I may tend to run something, and if anyone says anything, ask forgiveness later. Security is pretty tight where I am – I have gotten dinged on xp_cmdshell but so far nothing on reading from AD. If for some reason you can’t run anything against AD, I would find the person over that and find out why, and let them know what you are trying to do.

Thanks again to everyone who attended. If you have any other questions leave a comment. 🙂

3/12 – Webinar : Beginning Automation with Powershell

Anything I can do to reduce the time I have to spend dealing with otherwise time-sucking tasks gives me a happy. Currently, where I am, I have reduced our daily deployment process to a single Powershell cmdlet with a log file review. All the steps that normally went into each deployment (applying SQL scripts, data updates, updating the TFS task, sending an email that the deployment is done) are handled by Powershell, and the process accepts multiple deployments at the same time. As long as there are no errors in the log file for a deployment, there is nothing more to do. There’s an error? Run the same cmdlet with the rollback option.

I am still working on improving this process, from trying to get the error handling to work the way I want it to, to incorporating the automation of check-in to source control of the changes that were just applied. It is a work-in-progress that will continue to reduce the amount of time spent on what would otherwise be manual tasks.

This work led me to the idea for a session on Powershell and automation of processes. Join me and Pragmatic Works on Thursday, March 12th from the comfort of your own desk at 11am EST/10am CST for Beginning Automation with Powershell. This demo-heavy session will go over some different Powershell cmdlets and automation concepts that you can take and build upon in your own environment. Powershell is a tool that no DBA should work without. A development background is helpful but not necessary – what DBA would not want to spend a few hours writing code for a process that will save them from having to do a repetitive manual task over and over again? Automation frees up time for us to do other projects that we want to spend time on and grow our skill sets.

Have questions about this? Leave a comment below. See y’all there. 🙂

#SQLSatPhoenix This Weekend!

Both the SQLSat Austin and Albuquerque events were great – now on to Phoenix. I will be giving two sessions there – Deadlock, Block & Two Smoking Barrels: Breaking Down Blocking and Deadlocks and Making the Leap from Developer to DBA.

The first of the two is a new session for me. When it comes to blocking and deadlocks, I like to be able to identify the cause (and sometimes the culprit) and have the information needed to resolve the issue. Some methods are easier, while with others, you also have to think about the footprint of the troubleshooting itself.

With Making the Leap from Developer to DBA, this session has evolved with time and my own experiences. Anyone who is looking to transition to being a DBA full time should attend to get a real-life perspective on migrating into this role and some of the things you can look forward to.

On top of all this, I have also been invited to be part of the WIT Panel. Come join my self and some other amazing women during lunch as we share and discuss confidence and our experiences in IT.

I’m looking forward to another great SQL Saturday as well as meeting everyone in Phoenix. See y’all there! 🙂
