Well it’s time for another great Data Platform Summit in Bangalore India. The team there has been kind enough to allow me to present a pre-con this year (third year in a row). This year I’ll be changing up my precon a little bit. Instead of talking about SQL Server, I’ll be focusing more on Azure and everything that the DBA that’s going to be moving into Azure needs to know about Azure (or at least as much as I can cram into a 7 hour session, I’ve got 4 days worth of material I can present but only 7 hours to present it).
During the session this year we’ll be learning all about the components that you need to get know about and setup to successfully run a high volume SQL Server in a VM in the Azure Cloud.
This session is really important to the Indian market specifically as Microsoft has just opened new Azure data centers in India in the last year, so more and more Indian companies should be expecting to move workloads to Azure. This session will give attendees the knowledge to become the experts within the organizations to be able to help their companies move into the Azure Cloud.
So what do you do now? You go signup for the all day PreCon session and then come to the session. Nice and easy.
Join me on September 14th, 2017 for my annual PASS Summit Attendee Orientation webcast. Like in prior years this is the must see pre-PASS Summit webcast were you’ll get all sorts of information about the PASS Summit for this year. This includes sessions, directions around the convention center, parties, Speaker Idol, and much, much more.
Getting registered for the webcast is simple. Go here and fill this out. That’ll get you the link to the URL for the webcast and the ICS file to put into Outlook so that you get a reminder for the webcast.
There will be reminders posted on Social Media, but even if you haven’t gotten approval to go to PASS yet, get registered for this webcast so you don’t forget. After all, it’s free.
I’m pleased to announce that PASS has made the mistake of letting me run the Speaker Idol at the PASS Summit for another year. If you
haven’t seen the speaker idol before it’s kind of like the TV show of the similar name. But instead of winning a contract that’ll never be fulfilled by some recording company, you win a speaking spot at the next PASS Summit. One of the parts I love about Speaker Idol is that by the end of the PASS Summit we know who are first speaker is for the next year. It also gives 12 speakers the chance to speak at the PASS Summit lightning talk style with immediate feedback from our panel of judges, who are all top PASS Summit speakers.
If you’ve always wanted to speak at the PASS Summit but haven’t been selected, this is your chance to get in front of the community and make yourself known. Several past contestants of Speaker Idol have gone on to speak at that PASS Summit even without winning the competition. One of the benefits of competing in the Speaker Idol competition is that it gives you visibility to the program committee, the judges and the community at large so that more people are aware of you and your speaking style. This alone will increase your odds of being selected to speak at the PASS Summit in the future (if you don’t win the competition).
It you competed in a prior speaker idol (and you didn’t win a speaking slot at the PASS Summit) you’re welcome (and encouraged) to submit again.
Here’s a few blog posts that some of our prior contestants have posted about the experience.
Now for the rules (or you can just sign up here):
You must have spoken at one of the following events (in a format other than a lighting talk, where your session had at least 30 minutes of content delivered by you):
- SQL Saturday
- SQL Bits
- SQL Server Days
- Microsoft Ignite
- Dev Connections
- Other large event with a national or international reach
You have not spoken at the PASS Summit of PASS Business Conference for a breakout, spotlight or pre-con session. (If you gave a lightning talk and no other session you are eligible.)
You are not scheduled to speak at the 2017 PASS Summit.
You will be in Seattle during the PASS Summit (attending PASS isn’t needed, and if you aren’t attending PASS we will get you to the session room for Speaker Idol).
You are available to attend which ever speaker idol session(s) you are assigned to (including the final session on Friday afternoon).
You have a 5 minute technical presentation which you can give. (Time management is your responsibility.)
You sign up on the registration form before September 8th, 2017 at 11:59:59pm (23:59:59) according to Google’s time function in their spreadsheet application. Because of the tight schedule between this announcement and PASS late applications can’t be considered.
You are not a member of the PASS Board of Directors or an employee of PASS.
You are not employed by a sponsor of Speaker Idol
If a contestant drops out of the contest before the PASS Summit starts the organizer (Denny Cherry) will reach out to the next person on his list that wasn’t accepted and offer them an position in the contest. People will be offered spots in the competition until someone accepts. The organizer will NOT announce how many people if any turned down a spot in the competition.
If a contestant drops out of the contest during the PASS Summit (for purposes of this clause “during the PASS Summit” is defined as from the time that Denny gets to Seattle, which will probably be Saturday or Sunday before the conference, until Friday afternoon) no changes to the lineup will be made.
If a contestant wins their round and can not continue to the finals for any reason, the runner up from their round will be declared the winner of their round and will be moved to the finals.
If a judge is not able to complete the competition they will not be replaced.
Other Idol Rules
The wild card winner will be selected by the judges at the end of the Friday morning round from the runners up from each round. If a winner is not able to compete in the finals, and the runner up is already speaking in the finals, the judges may consider all contestants from that round as eligible for the wildcard slot.
Judges do not have to recuse themselves because a friend is in the competition. Judges are expected to be fair.
You are responsible for your own travel to the PASS Summit to compete in this competition.
You may present your session in any format that you’d like. You can view the recordings from 2015 (the 2016 recordings current require that you purchased the recordings, I’m working on fixing that) via PASS TV.
While you can use any format when giving your presentation that you’d like, it is recommended that you use a format which will show the judges how your presentation skills will translate from a 5 minute session to a 75 minute session as that’s how long the PASS Summit sessions are.
Contestants are allowed to watch the other sessions during speaker idol and make changes to their presentation as they see fit.
In case you missed it above, the Sign Up Form is <- there.
Stay tuned for announcements on the judges and the contestants. (Judges won’t be announced until after the PASS schedule is finalized as I need to see who’s available to be a judge.)
After you sign up, shortly after the sign up period closes, the applicants will be sifted through and the 12 contestants will be selected and emailed. They’ll have a short period of a couple of days to accept the invitation to compete. Once we have 12 “yeses” we’ll all get on the phone to talk though what you should expect, talk about what kinds of sessions you want to give, and get any questions answered from this years 12.
That’ll give a few weeks for the 12 contestants to put together their slides for the speaker idol and prepare to give the best 5 minute sessions that they can.
One of our customers ran across some interesting data within their Azure bill. Specifically they were
looking at the billing for their SQL DW, but this same issue can show up in the billing statement for other services as well.
This customer has a single SQL DW setup with a service tier of DW300. Looking at their monthly bill last month, something looked kind of odd. A snippet of the bill is shown below.
Some things stand out to me when looking at this bill. First is the service that is being billed. It doesn’t say how many DWs we’re being billed more (more on that later).
Something else odd is that the SQL DW shows being billed for 1220 hours. Now in theory the most number of hours for any single service you can be billed for in a single month is 744 as that’s 24 (hours) *31 (days), but here we’re being billed for 1220 hours. Now we know for a fact that this SQL DW is powered off at times, so how are we using this resource for more than 31 days in a month?
The last oddity is the rate. $1.46 an hour. This points us to the reason for all of these strange numbers. That’s the rate to run a SQL DW at DW100 for one hour.
The entire SQL DW service is built around 100 DWUs and incrementing the cost and scale up from there. If you look at the pricing page for SQL DW you’ll notice that the price increase is linear. This is for a reason, it makes the billing MUCH easier.
So even though we’re being billed for 1220 hours, the SQL DW actually only ran for about 406 hours and change.
When reviewing your Azure bill, especially for PaaS services, keep in mind that the billing may not look like you expect it to because they have configured the billing at a lower tier then used a multiple to get to the correct pricing.
Let me start by saving to every event organizer thank you for running the events you run. This post may come off a little bad-tempered, but please know that this comes from me wanting to make your life easier, and to make your events even better than they already are.
Please, please communicate with potential speakers WELL in advance of your event. If you’ve got a list of speakers that you know based on their abstracts you’ll be accepting (even if you don’t know which specific session you’ll be picking) then let those speakers know that you’d love to have them speak at your event. If you don’t know yet which session you want from them, let them know. This gives them the chance to start booking travel as quickly as possible if they are coming from a remote location. If international airfare is required for the speaker booking early can mean saving hundreds of dollars in flight costs being saved. If the speaker is paying for the flights out of their own pocket this can be a big benefit.
Doing It Right
A perfect example of this is Data Platform Geeks Summit in India. The team there has been great about working with the international speakers several months in advance, in order to let them know that they’ve been accepted so that flights could be purchased. In addition to being able to book flights in advance some of the speakers were able to book other speaking engagements in Southeast Asia maximizing the ROI on the expense of booking the flights to get to the other side of the planet.
The more communication that you can have with your speakers and sponsors the better as it keeps everyone advised on what’s going on and what needs to get booked and shipped well in advance. This holds true even after you’ve announced your schedule—you won’t annoy speakers by over communicating.
The Trump Administration has put together an Election Integrity Investigation commission to investigate voter fraud here in the United States. They are requesting all state governments hand over a LOT of personal information including (but not limited to) your name, address, birthday, political party (if recorded), last four digits of your Social Security Number, which elections you’ve
participated in since 2006. The data is known as Personally Identifiable Information (PII).
This is not a political post, that’s for political folks to talk about. I’m an information security professional: I want to talk about the massive risk to all our personal data if this information is sent over.
Here’s the letter that was sent to the states. First let’s review how the data should be sent in: one option is via email. We all know email isn’t secure, witness the email hacking and data drops from the last election. Transmission of the information alone puts every individual at risk of a hack. Alternatively, they offer the SAFE system as a backup. Based on the URL, the system is run by the US Army, not the commission, which will require a secondary transfer of our PII, under the assumption it’ll end up in the correct place, won’t be lost, released, etc. Moreover, it’s entirely possible it could arrive at the U.S. Army and still be transferred via email, nullifying any attempt made in the name of personal security.
Now let’s dig into that second to last sentence there. “Please be aware that any documents that are submitted to the full Commission will also be made available to the public.” So the panel is going to take everyone’s personal data, the exact data needed to steal someone’s identity, and release it to the public? Where anyone can download it?
Finally there’s the request for the last four digits of your social security number, which is the most pernicious and misguided request in the letter, because it is the key to your identity. The digits you would be handing over are the most random ones in your coding as they are in sequential order of your request for a card. The first five, if you applied for a social security number before 2011 (which is almost all of us) are sequencing based on location: the first three digits were assigned based on the ZIP Code of your mailing address at the time of your social security application. You may still live in the same zip code, or you can be easily tracked for previous addresses online. The second two digits are a group number based on location, again possible to reference it with a little work.
As a final consideration, there are also people who need to stay hidden for their own protection: spouses who do not want their abusers to locate them, witnesses from court cases, adoption issues, even celebrities who don’t want to subject themselves to stalkers or superfans constantly knocking on their front door.
And there is no “opt out” for an individual, the record is historical in nature going back to 2006 and presented by the election board, not the individual.
This whole project seems to have been construed without consultation with anyone in the information security sector and it shows. Even if the panel could overcome the transfer and privacy issues, we have no way of knowing how this information will be stored (assuming that it isn’t released to the public as the letter suggests) so that confidential data can actually remain confidential.
Thankfully many of the Attorneys General from across the country have said that this won’t be happening because of state privacy laws. Encourage them, and your state election boards, to keep fighting this. Hopefully the commission will figure out that this is a horrible idea.
On Saturday a lot of winners of the Microsoft MVP award got emails that they’ve been waiting for telling them that they were renewed as MVPs for another year. Some people didn’t get renewed for one reason or another, and only Microsoft knows why.
You may have expected to see me tweet that I was renewed as a Microsoft MVP on Saturday, but I didn’t. That’s because I wasn’t. Now this doesn’t mean that I’m not an MVP, because I am. The thing is that unlike most of the other MVPs I wasn’t up for renewal as a Microsoft MVP July 1st. The reason why is a little lengthy, so bear with me.
Back in the olden days of the MVP program (2016) there were 4 renewal schedules, at the top of each quarter. I received my award in October the first time around, so I got renewed every October. When they announced the change to the program around the MVP Summit last year they had just renewed the October awardees so technically we’d all still be MVPs when renewal came up in July. Because of that Microsoft decided that we’d keep our October award expiration, then they’d extend that until the next July (our awards should have expired October 2017, so they now expire July 2018). Because of this we all get to keep our awards for an extra 9 months (January and April award winners got extended until July 2017, the July award winners didn’t get any extra time).
So yes, I’m still an MVP. You can tell who’s an MVP by looking at the MVP webpage. Now this isn’t a perfect solution as some MVPs opt to hide their profile for one reason or another, but it’s a pretty good bet that if someone isn’t listed there they aren’t an MVP anymore, and if they are listed there they are an MVP. As soon as someone is no longer an MVP there profile is removed so there’s no risk of finding people that aren’t MVPs in the MVP directory.
Congrats to the MVP Class of 2017, you’ve all earned it. See you at the next award cycle.
Running SSRS with the ReportServer and ReportServerTempDB databases has been supported for a while now. If however you want to use scheduled delivery of reports you need to do some extra stuff to make this work.
The first thing that you need to do, if when setting up the SSRS instance you need to move the AG from Replica to Replica to setup the correct permissions within the MSDB database (or manually setup the permissions for SSRS within the MSDB database. The easy solution is to make the SSRS database a member of the db_owner role in msdb. This is because apparently the permission that the SSRS configuration manager gives the SSRS account doesn’t include the ability to add a category to the msdb database, which it needs to do. db_owner was the easy fix in our case, and the risk of SSRS doing something it shouldn’t in MSDB is minimal.
That’ll allow SSRS to create all the needed jobs on each node of the Availability Group.
The next thing you need to do is configure the Availability Group to restart SSRS after the AG fails over. This needs to happen because SSRS doesn’t recreate the jobs when it reconnects to the AG, it only does this on SSRS startup. If you are running SSRS in a farm (which you should be doing for high availability) you only need to restart SSRS on one node of the farm.
This can be easily done with a three line batch file, which you configure as a generic resource in failover cluster manager within the resource group which hosts the availability group. Personally I put this script in c:\scripts with some other stuff.
sc \\ssrs-server stop ReportServer > c:\scripts\restart_ssrs.txt
sc \\ssrs-server start ReportServer >> c:\scripts\restart_ssrs.txt
The first line stops SSRS, the second starts it. The third line pauses the batch file so that it doesn’t complete and quit. If it did that then failover clustering would see that as a failure and a failure trigger a failover (or if you disable that a failed service). And since I like my clusters all green and happy, I pause the batch file so it sits there forever. The > c:\scripts\restar_ssrs.txt is logging the output to a text file.
Yes, I could have done this with PowerShell but it wouldn’t have gotten me anything except for more complex code while I check to see if the service is down, then attempt to start it. And SC works just fine for this.
The last thing you need to do is make the computer accounts for all the members of the availability group members of the local administrators group of the SSRS server. This needs to be done so that the service can be restarted (or in some other way give these accounts access to restart services). It needs to be the computer account of the member nodes, not the computer account of the cluster as the batch files run under the context of the computer.
After that, when an AG failover occurs your SSRS will restart within a minute or two and create any missing jobs.
Now the downside here is that you’ll have a bunch of jobs failing on the secondary replicas, but I’ll take that over a non-working configuration.
Recently Microsoft Azure introduced the ability to have multiple front end IP addresses on an Internal Load Balancer. This allows for
Failover Cluster Instances to have multiple instances per cluster, and Availability Group deployments to have multiple Availability Groups per deployment.
But with this improvement comes the need to be very careful about how our probe ports are setup on things. Otherwise things aren’t going to work exactly as we expect them to. And we’ve seen this on a couple of different deployments with customers now.
Much of this problem comes from the fact that all the sample code that’s out there and talks about how to setup an FCI or AG assumes a single front end IP and a single probe, as that’s all that was available for years.
Thankfully solving this is actually pretty straight forward. We need a single probe configured in the Load Balancer for each front end IP address that we configure in the load balancer. That means that each IP that we have configured in failover cluster manger also needs it’s own probe as well. If you don’t setup a separate probe for each clustered IP address then the only way to ensure that everything works as expected is to have all of those Clustered IP addresses on the same node of the windows cluster.
What I like to do is something like this.
The reason that we have to do this is pretty basic, you just have to remember how the probe ports work. The probe port that you configure in Windows isn’t listening on the clustered IP Address. It’s listening on 0.0.0.0 or all IP addresses. Also, the Internal Load Balancer doesn’t connect to the probe port on the clustered IP, but instead on the clustered node’s IP address.
We can see this is we run netstat -a -n on the node that’s hosting the Availability Group replica. In this case the node of the VM is 10.0.0.8 and the probe for the AG is listening on port 59999. The SQL Server Availability Group is listening on 10.0.0.14 in this case and the cluster root of the Windows Cluster is listening on 10.0.0.13 with it’s probe on 59998. Before we reconfigured this cluster in this way, if the Cluster root and the AG were running on the same node then everything was fine. However if either one was moved to a different node of the cluster then connectivity to SQL became “interesting”. SSMS would only draw 1/2 the folders it is supposed to show. The application got impossible for users to use, etc. Basically everything broke and fell apart. Once we realized the problem, the fix became pretty straight forward. Change the probe configuration for the cluster root (10.0.0.13 in this case) to another port and configure the Internal Load Balancer with another probe, the configure the load balancing rules for the cluster root to use the new probe. Once all that way done everything started working as expected.
These sorts of configuration problems can creep up on you. This environment was 6 months old when this problem first showed up. Because until then, the cluster root and the AG always happened to reside on the same node. But recently that changed because the third node of the cluster (we have an extra machine in the config so that we are using a majority node set quorum configuration) lost network, then got it back. This caused a cluster vote and this machine became the cluster manager so the cluster room (10.0.0.13 and it’s network name) moved to this node causing the probe to be open on two machines and causing all hell to break loose as 1/2 the SQL connections were being directed to a server that didn’t even have SQL installed on it, much less have the Availability Group listener running on it.
The probe is very important to configure for everything that you want to load balance to, it just needs to be configured correctly.
It’s shockingly easy to setup as well. You’ll need this WordPress plugin to handle the actual authentication. It’s not in the WordPress gallery, instead it’s on GitHub so you’ll have to download it from there and install it.
Once it’s setup you’ll need to log into the Azure portal and tell Azure Active Directory that you’ll have a new application using Azure Active Directory. Then copy the keys from Azure Active Directory to the settings page of the Plugin.
Now don’t worry, there’s instructions on the GitHub page for the plugin that’ll walk you through setting it all up. It frankly took me all of about 5 minutes to get it setup and working.
Now if your WordPress is configured to prompt you to do a math problem when you login, you’ll need to disable the Protect feature in the Security tab in the JetPack Security tab.
The benefits of using Azure Active Directory for your authentication are enormous, including robust Two Factor Authentication, corporate password policies, granting access via AD group membership as well as the fact that your login process is now backed by the Worldwide Azure Active Directory infrastructure.
If you have WordPress and have access to Azure Active Directory I would HIGHLY recommend setting up this authentication process.
