How should I manage a thousand database schemas?

Brent Ozar: Joe O’Conner asks, he says, “Any suggestions on tools or methodology for standardizing a schema to accommodate a thousand plus instances that may all be slightly different?” Joe, let me ask a follow-up question too if you can return back and ask, do you want them to be different or do you want them to be the same? That will probably influence the answer that we give you there.

 

Why is replication showing high CPU use?

Brent Ozar: Let’s see here, next up. James Kelly says, “In SQL Server 2005…” I’ve got to stop using last names because somebody is going to ask a question they’re ashamed of—like James Kelly—who has SQL Server 2005. Poor guy, god bless him. It’s not a bad database platform, it’s not horrible. It’s better than 2000 was. He says sp_replmonitorrefreshjob causes high CPU when suspended mode on the distribution database. What should I look into in order to reduce CPU? Tara, I’m even sorry I read that but you’re the only one here that would be remotely qualified.

Tara Kizer: Yeah.

Brent Ozar: You know anything about that? I don’t know anything about that.

Tara Kizer: I haven’t encountered that and I used replication for, I don’t know, ten years or so, what is meant by suspended mode on the distribution database? Is that when the jobs are not working?

Brent Ozar: I think he’s doing sp_WhoIsActive. I bet he’s doing sp_WhoIsActive.

Tara Kizer: Oh, but suspended doesn’t necessarily mean anything. “Causes high CPU…” Are you sure it’s that refresh job that’s causing the high CPU? If it is, I would start taking a look at the replication monitor and looking for what kind of latency you have in the queues. I would imagine you’ve got a large backlog and maybe that’s why it’s taking it a while to pull up the data.

Brent Ozar: That makes sense. So my webcam probably just froze. I all of a sudden got pouring down rain here, you could hear it in the building, just all of a sudden it pours down and immediately my internet dies. I’m like, oh, it’s going to be like that. It’s going to be like that.

Richie Rump: What kind of backwater [inaudible 00:01:41] are you in?

Tara Kizer: Yeah, I was going to say. Richie is like, it rains all the time.

 

Brent Ozar: Dennis says that MS certs are great at uncovering what areas you don’t know. Yeah, but also what areas you don’t need to know.

Tara Kizer: Or what areas you do know.

 

What do you think about the new Microsoft degree for data science?

Brent Ozar: Greg asks an interesting follow-up question. “What do you guys think about the new Microsoft certs for data science?” Did you guys see that new degree?

Erik Darling: Yeah.

Brent Ozar: Richie clearly saw it. Erik saw it.

Tara Kizer: I only heard about it, I haven’t seen it.

Brent Ozar: I didn’t look at it, I just saw the headlines and went, “Hmm, what?” So Richie, you made such a face. There must be a good reason you made that face, or a bad reason.

Richie Rump: Calling it a degree is weird to me. It’s just strange. I don’t understand it. I spent five years getting my four-year degree, so am I going to spend six years trying to get my seven-year MS degree? I don’t understand. I don’t understand it.

Erik Darling: Is it really that long term? I thought it was like hours.

Brent Ozar: Well, but it’s also the kind of thing you’re going to do spare time. It’s not like, I hope to god you’re not going to take out a loan and go do that kind of thing. Go spend $1,000 on exams or something.

Erik Darling: It was like $500 or whatever, or something. I don’t know, I didn’t read all the fine print.

Brent Ozar: There’s going to be like no training on it, third party for a while, because it’s all brand new. And that platform changes so fast. I’m like, I don’t get that. So I’m not keen on that.

Richie Rump: I mean basic stuff it doesn’t, but I mean is that what they’re going to teach? They’re going to teach me the basics of data science independent of their platform? Or are they going to say, “This is how we do it at Microsoft?”

Erik Darling: … golden hammer from Microsoft.

Brent Ozar: There was a statistics course in it, or like one statistics test. But then the rest was heavily Microsoft. Yeah, exactly. I was like… especially if, you want to know more than one toolset if you’re going to do the data science thing. In the database community, you can know just Microsoft and you can make a wonderful living for yourself. It’s fantastic. Data science is not—you don’t get to learn just one tool, you’ve got to learn a lot of tools.

 

Yadda Yadda Yadda

Brent Ozar: James says he’s waiting for his boss to get a credit card and register for the Senior SQL DBA class next week. Cool, very cool. We’re doing an online class there for four days.

 

Brent Ozar: Nate Johnson says, “SQL Server Management Studio 2016 says it won’t work with 2005 instances but it’s working okay for me. Have you guys used SSMS 2016 with 2005?” I will answer that one. No, we were doing La Cucaracha the day that 2005 was out of support. Erik was doing a countdown for that date. He could not wait. So we haven’t used it at all. Usually what that means with Microsoft is just that they don’t have it in their test matrix anymore. It usually works, there’s edge cases where it won’t but usually you’re okay.

 

Brent Ozar: Thomas says, “I think if you’re new, the certs are good because they show that you’ve been at least exposed to areas of SQL Servers. In my day job, I don’t do any analysis services, reporting services, or integration services so the certs will give me some exposure to them in an organized way.” You can die of exposure, you know that. That’s dangerous.

Erik Darling: Naked and afraid.

Brent Ozar: Naked and afraid, in indexes.

Richie Rump: Unsubscribe.

 

What should I do about an index rebuild that takes 90 minutes?

Brent Ozar: Michael Tilly asks a question that is really inconsistent, multiple parts, and a novella. So if you guys want to read into it, we’re going to read through it. Michael says he has a question about index rebuilds. He works at a large university, actually Brent’s alma mater—I don’t think you’re allowed to say that unless you graduate—and University of Houston for three semesters, so yeah. “I have a large students table…” 35,000 students a year, if I remember correctly. “That has many, many millions of rows of active and inactive students. I have a maintenance plan that does a nightly index rebuild on the…” Holy cow. “On the…” Yeah, already we’re shaking our heads. “It seems to take an excessive amount of time, 90 minutes. Right now we’re rebuilding it online. I’m thinking that maybe I should turn it offline. What should I do?”

Erik Darling: I think you should turn that maintenance plan off.

Tara Kizer: Off, yeah, why are you doing this?

Erik Darling: Because my whole thing with what you’re saying is like you probably get a whole bunch of students once a year.

Brent Ozar: What are you trying to say?

Erik Darling: I’m trying to say that you enroll students once a year.

Brent Ozar: Some of them graduate.

Erik Darling: Yeah, but you enroll students once a year. So like you add in a new crop of students and at that one point, your table might be fragmented. Then after that, you might have some dropouts, but you just change them to inactive. You don’t like delete them from the table. I can’t imagine the students table is getting heavily fragmented aside from enrollment and graduation. Or like even then, graduation is probably just switching to inactive. So I just can’t imagine a way for fragmentation to even accrue that much on a daily basis.

Brent Ozar: I think if they had an index on estimated completion or estimated graduation date, my record would have moved around a lot during the course of me being there. But I think for the rest of the people, not so much.

Richie Rump: So what can he do, Erik?

Brent Ozar: Oh, yeah, good point.

Erik Darling: You would have to go back. I wrote a blog post recently, no surprises there.

Brent Ozar: What?

Erik Darling: Peanut gallery, all of yous—it was about when you want statistics instead of an index but it touched a little bit on why index fragmentation isn’t really that important and up-to-date statistics are far more important. So what I would do in your shoes is I would stop rebuilding the index every night. I would stop rebuilding indexes pretty much in general and then just update the statistics daily and see how you fare. You’ll probably just end up in the same place now where performance is what it is because the statistics got updated, it didn’t reflect all of the fact that you were rebuilding the index every night and wasting hours and hours of your life and precious disk and CPU time.

Tara Kizer: And for the update statistics, because you have several million rows of data in that table, you could probably just get away with like a 20 percent, 30 percent sampling. You probably don’t need to do a full scan on that table.

 

How do I resync AGs when replicas have different drive letters?

Brent Ozar: Nathan says he’s got an availability group and they very rarely have to resync their dbs. They’ve added new databases and “we also have to start syncing those. But we’re not able to do a full sync because the drive letters don’t line up anymore. For example, I have some drive letters that exist on the primary but not on the secondaries. Is there a way to automate this process without doing backups and restores and joining them manually?”

Tara Kizer: You have to do a backup and a restore and say with move in order to get the different drive letters. So, no. There isn’t a different way.

Brent Ozar: Yeah, that blows.

Erik Darling: Rename your drives.

Tara Kizer: Yeah, rename your drives. Script this out so that it’s automated at least, you’re not having to do it manually.

Erik Darling: Yeah, there are actually a bunch of questions on dba.stackexchange.com about how to automate adding databases to availability groups. There are some, not like fully fleshed out scripts, but there were some pretty good outlines of scripts on there about how to get started but you are going to have to make certain considerations for the fact that you have different drive letters and that stuff when you’re writing your script.

Brent Ozar: I want to say there’s a trick with the SUBST command too. Like there’s this command line S-U-B-S-T that can let you make fake drive letters to point to other drive letters. Totally don’t quote me on that but just like google it to see. I’m sure it’s not supported but just as a fun trick.

 

Why isn’t Brent giving money to the University of Houston?

Brent Ozar: Michael from my fake alma mater comes back and says, “As it turns out, we do have constant fragmentation because we keep all our student history.” Yeah, I know because you keep asking me for donations which seems pretty stupid because I dropped out. Why would I give you money if I didn’t finish? He says, “As we constantly update the home address and phone number and other info, so lots of updates.” Listen, you’ve got to unsubscribe me. I’ve asked several times. That’s not true. Although you did bulldoze the dorm that I was in and I was a little pissed off about that one.

 

How do I change account owners on an endpoint?

Brent Ozar: Let’s see here, Thomas says, “We have a former DBA who granted the rights on the service accounts to an endpoint.” I think he used his own personal service accounts on an endpoint, like mirroring or availability groups. “I can’t drop his login without changing that. Is there a way to change which service accounts have permissions on an endpoint without dropping and recreating the connection? I tried ALTER AUTHORIZATION and that didn’t work.”

Tara Kizer: What’s the endpoint being used for? I mean can’t you just rebuild whatever that is? Is it mirroring? Is it an availability group? What is it?

Brent Ozar: Yeah, it should be a brief outage, right? Just recreate it.

Tara Kizer: Yeah, exactly, get a maintenance window for this.

Brent Ozar: Yeah, I like that. And you want to be patching anyway. I’ll also take the crazy thought of, “Why change it?” Leave it under his account. As long as you have the password.

Tara Kizer: Or maybe rename it so that it’s like a service account now and not someone’s—you know, because the [inaudible 00:10:26] will remain the same. So it will appear as a regular account at that point.

Brent Ozar: The service account formerly known as…

Tara Kizer: Yes.

 

More about synchronizing a thousand schema differences

Brent Ozar: Joe comes back with the thousand schema thing. Joe says, “Are there any suggestions or tools or methodology for standardizing to a single schema that will accommodate slight differences in a thousand plus instances without losing any data?” Wow.

Tara Kizer: It’s a thousand plus SQL Server instances and trying to get them all into one database with different schemas? I’m confused what the question is.

Brent Ozar: You know what I bet he’s doing, Erik. I bet he’s doing what your favorite ISV does. Yes, I bet, so we blog about this kCura Relativity, it’s a piece of software out there and customers are allowed to change tables but your deployment scripts still have to work. How do their deployment scripts work, like when they drop a new version of their app?

Erik Darling: The last time I did it, the deployment scripts were in a numbered folder and called by a C# program—by some program. Don’t quote me on the C#. But it’s tough because you have to specifically change only your indexes. The last thing didn’t go so well because there was some custom objects that they didn’t account for that I had to like go back and manually change. So I don’t know that I would recommend that process as an overall process. But, you know, they do alter tables directly from scripts and everything.

Brent Ozar: Run them in order based on their version upgrades. They also have dozens of developers to manage that kind of thing.

Erik Darling: Yep.
Brent Ozar: Lee asks, “I’m curious, why does the model database, the system database model, why does it have recovery set to full?”

Tara Kizer: Well that’s just because it’s the default for new databases so when you create a new database and you don’t provide all of the settings, it uses model as the template and it’s just the default that Microsoft has set. I really wish that they would switch it to simple. If they’re going to have everything be default to full, then how about you default to setting up transaction log backups too?

Brent Ozar: Oh, yes. Yeah, I like that. We should have a connect item for that.

Tara Kizer: Closed. Won’t fix.

Erik Darling: Immediately.

 

Why does my log file grow even in simple recovery model?

Brent Ozar: Lakshmi says, “I have a database in a simple recovery model and we make a lot of changes on say Friday nights. The transaction log grows to like 20 gigs, why is it that my log file is growing even in simple recovery model?” Did I say simple recovery mode at the beginning? That’s Tara’s hot point.

Tara Kizer: It’s one of mine, yeah. Everyone says “recovery mode.”

Brent Ozar: Yeah, simple recovery model.

Tara Kizer: You’re logging of your transactions doesn’t change based upon your recovery model. It’s still the same amount of logging. So if you have 20 gigabytes of data changed, or at least logging, it’s going to be the same with simple or full. It’s what happens at the end of the transaction is what’s different between the two recovery models. With simple, that is cleared from the transaction log after it completes, either rolls back or commits. With full, it stays in there until something backs up the transaction log. So the size doesn’t change based upon recovery model.

Brent Ozar: Some yoyo doesn’t BEGIN TRAN, your log is going to be growing for a while.

 

Does antivirus slow down SQL Server?

Brent Ozar: Matthew says, “Have you guys ever experienced noticeably degraded performance as a result of having antivirus installed on a SQL Server?”

Tara Kizer: Yes. Definitely. That’s why you need exclusions in place. At one point we had something like 46 exclusions on the database servers. I think it went even higher. I forget what the number was, 60s or 70s I think. But there’s a list of exclusions that you need to have in place on a SQL Server. It’s SQL Server executable, your MDF files, LDF, NDF, all these… There’s just tons of them and I believe that this is documented somewhere, what your exclusions should be. I don’t know where it is though.

Brent Ozar: There’s a KB article. If you Google/Bing whatever “SQL Server antivirus.” Then you site: support.Microsoft.com. If you site: in Google and restrict it to a single site you’ll get the answers just from the Microsoft Knowledge Base.

 

Where can I read about lifecycle management?

Brent Ozar: Graham says, “Other than Microsoft’s content,” so I guess we know how he feels about Microsoft’s content, “are there any good end of life or lifecycle management references for SQL Server versions?” Did you guys ever see any good database documentation around when you should upgrade or how to handle upgrades other than Microsoft’s?

Erik Darling: Most of the ones that I’ve seen reference a lot of Microsoft’s stuff, like using the Best Practice Advisor and the Upgrade Advisor and using those as sort of jump off points for what you should do from then on out. Microsoft does, at least I think, a fairly decent job for the Upgrade Advisor stuff, like giving you the scripted out things that you need to do your migration with.

Brent Ozar: Tara, with all the SQL Servers that you guys managed, how did you do processes for upgrades? Did you like write out, “Here’s exactly what we’re going to do” and which order, or was it like different every time you guys did a SQL Server?

Tara Kizer: When I was at QualComm and I was the primary DBA for a specific division it was really based upon what projects were in the pipeline and if we could get an upgrade placed into that project. If they were doing a major release, maybe we could get that database upgraded. I’m sure to this day they still have SQL Server 2005 instances out there. I’ve been gone from them for about three years but I’m positive just because how many there were when I left. There weren’t any 2000 but tons and tons of 2005. Some of them probably just get stuck there. Not all companies care about not being supported by Microsoft. So what if you don’t have any security hotfixes. If you have a secure environment, you may not care about that type of stuff. Companies really care about getting releases out, making their customers happy. Do they really care about the SQL Server version behind the scenes? The DBA team cares, you know, what do we have to support.

Brent Ozar: That’s why we still at the company we still run Windows 95 here at Brent Ozar Unlimited. It works really well.

Richie Rump: Well I’m on 3.11, that Workgroup edition.

Brent Ozar: I’ve been trying to get him to upgrade that Trumpet TCP/IP stack is just not…

Richie Rump: It’s an oldie but a goodie, man.

Brent Ozar: Oldie but a goodie, that Solitaire, no Minesweeper like 3.11.

Richie Rump: Hot dog theme, that’s what it is.

Brent Ozar: Oh my god, the hot dog theme is correct. So for those of you who ever get out in the community if you ever get the chance to Erland Sommarskog speak, Erland Sommarskog is a presenter in the SQL Server community and he usually uses the hot dog theme on his desktop. It’s just awesome. Comic Sans everywhere, pastel colors.

Tara Kizer: That would drive me crazy.

 

How often should I patch my SQL Server?

Brent Ozar: Adam asks, “What do you guys recommend for patching? What is a good balance of staying up to date with SQL Server patches while not just being on the hamster wheel continuously and doing constant updates? How often do you recommend patching SQL Servers?”

Tara Kizer: So based upon these large corporations that I’ve worked with, most of them want to do monthly patches. As the person who has to do the patches, I don’t want to do monthly patches because it is painful when you have to do 100 servers, 700 servers. We had a lot of servers that had to be patched. It wouldn’t just be one person having to do all this patching, it would have to be a team of people. It was disruptive. There was always some issue on some server that patches would not work, maybe failovers weren’t working that day. There was always some issue. It was just painful. It took way too much time. I wanted to do quarterly but large enterprises want to ensure that their environments are secure. Now, that goes against what I just said about SQL Server 2005 and not having security hotfixes—and these are the same corporations I’m talking about. But yeah, as one of the people on the patching team, I did not want to do it monthly. I would much prefer quarterly. Oracle doesn’t do monthly. Or, I should say, Oracle teams don’t do it monthly. I don’t mean just one company. It’s very common for them to do quarterly or twice a year. Why is it so important on Microsoft? I mean I realize it’s because of all the bugs there are as far as security goes.

Erik Darling: The really good thing about quarterly patches too is that it gives you some time to apply them to a development environment and let them burn it and make sure that they don’t do anything too funky. Because you know a lot of times a patch will get released and within the first 24 hours a lot of people will be raising their hands like, “It broke something.” So it gives you time to test things out as well. Quarterly is a good span of time to run across something awful.

Tara Kizer: Yeah, one of the companies I worked for, the patches came out on Tuesdays, “Patch Tuesdays” was what everyone called it for Microsoft patches. Then by Thursday we had to have installed, in production. I mean that was very aggressive. We ended up switching it to the following Tuesday, but still, it’s still very aggressive.

Erik Darling: So was that the “see you next Tuesday?”

Tara Kizer: Yeah. I mean, yeah, they’ve been installed in a test environment and maybe there’s some automated testing that has occurred on those, but that’s not enough time to burn those patches in.

Brent Ozar: That would suck.

Erik Darling: That’s horrible.

 

Should I use Desired State Configuration for SQL Server?

Brent Ozar: Graham says he’s trying to move to DSC, Desired State Configuration for SQL Server upgrades and migrations. I haven’t seen anybody successfully use DSC for SQL Server. Stack was trying to use it and failed. They had to give up on it and they have really bright PowerShell guys over there. I don’t think it’s quite there yet for SQL Server. It makes total sense for Windows, just not quite there yet for SQL Server.

Tara Kizer: I’ve never even heard of that.

Brent Ozar: The idea is you programmatically declare what you want the server to end up as and then Windows takes care of patching, installing the right features and getting it to that point for you. It’s not quite there.

Tara Kizer: Isn’t that what System Center Configuration Manager does? I mean it just knows what you’re missing.

Brent Ozar: Yeah, except you’re also supposed to be able to declare in code the whole state you want to get to, server names, what IIS tools you have installed, SQL Server features, where you turn things on and off. Yeah, it’s pretty tough.

 

Thanks for putting the Everything Bundle on sale

Brent Ozar: Lakshmi says, “Thank you, I just made my manager purchase the Everything Bundle from your training. Hope I can learn much more from there.” Well what are you doing on our free webcast? Go over to the good stuff. Here we’re just answering questions. These people don’t know what they’re doing. Go learn the good things. No, but thank you for picking that up. That’s awesome. We have a good time building that stuff.

 

Why does the Database Tuning Advisor only tell me to drop indexes?

Brent Ozar: Anker says, “Hi, I’m using the database tuning advisor in SQL Server 2014 for recommendations but it’s only giving me drop index recommendations.” [Laughter]… listen, I was trying to keep a straight face while asking this question. “Does the DTA ever provide any index suggestions too?”

[Laughter]

Tara Kizer: Why are you using DTA?

Brent Ozar: So why should he not use the DTA?

Erik Darling: DTA is craaaaazy.

Brent Ozar: How else are you going to get those?

Erik Darling: We have a tool called sp_BlitzIndex which is very helpful for finding missing index requests. There are some differences between it and DTA. Missing index requests are fueled by a process in the query optimization process called index matching. The stuff in the DMVs that gets logged is per query. The stuff that DTA logs is per workload. So you might have something in your settings that’s not giving you missing index requests for your workload that you can do both and you can click a bunch of stuff where you want suggestions, even for index views I found out recently. So that’s the difference between what they each do. But if it is only generating drop index recommendations and you have missing index recommendations enabled, I would really like to see what comes out of sp_BlitzIndex for you because that’s a wild time.

Richie Rump: Yeah, I have a blogpost that I was working on and it introduces a script that prevents the DTA indexes from being created.

Brent Ozar: So the blogpost, I don’t think it’s gone live yet.

Richie Rump: No, I was working on it. I haven’t loaded it yet. Still writing it. But the script is—I wrote the script. The script is great.

 

Nice video on the Dell DBA Days blog post

Brent Ozar: Greg Smith says, “Great video on the Dell DBA Days blogpost today.” We’re excited about that. We’ll all be down in Round Rock sweating through our shirts in August. We’re going to try and stay in the air conditioning.

Richie Rump: What else is new, Brent?

Brent Ozar:          What else is new.

 

What would you say to a manager who wants…

Erik Darling: There’s a really good question up top, if you don’t mind.

Brent Ozar: Oh yeah, who asked?

Erik Darling: It’s a Scott Kelly question. “What would you say to a manager that says they need an active/active HA solution but has no idea what that means?”

[Laughter]

Erik Darling: I think the most diplomatic way to handle that is to ask them to sketch out what that would look like and provide a budget for it. Then go from there because—just don’t walk into your manager and say, “You don’t know what that means.” Ask them to spend some time sketching it out, you know, a Visio diagram or just a whiteboard of what it would look like and how much he thinks it would cost. That’s where I would go from there if I was in your shoes.

Tara Kizer: This is a topic that I had to deal with a few times at one of the companies. Every few years management would be like, “We want to do active/active.” So every single time, we would go to the vendors and say, “What can we do to make this happen?” Here comes the price tag and we’d send it to management and they’d say, “Oh no, never mind.” It is very expensive. We’re talking two million dollars probably.
Erik Darling: In hardware, not just licensing.

Tara Kizer: Yeah, exactly. That’s several years ago last time I looked at it.

Brent Ozar: And Graham, if you get our download pack, if you go to BrentOzar.com and click First Aid up at the top, we have a download pack. We have a high availability and disaster recovery worksheet in there that helps you sketch out how much data you’re willing to lose, how long you’re allowed to be down for. One of the options is a zero/zero failover solution. It’s a million bucks and up. So just be honest and talk through it with the manager. The other thing I’d ask the manager is, “What’s driving that? What is that’s making you want that?” It may just be that they want cost savings or whatever and I’d say, “All right, so can you introduce me to someone else you’ve worked with at one of your past places who can help us design that?”

“Well, I’ve never worked with anything…”

“Oh, me neither. Sounds like it’s a good time for me to go to training.”

 

Are a lot of companies running SQL Server on Windows Core?

Brent Ozar: Let’s see. I had another question in here. Tom asks, “From what your team is seeing, have many companies started using Core installations yet? Windows Core.” Have you any of you guys seen SQL Server on Windows Core yet?

Erik Darling: Nada.

Tara Kizer: I started playing with it as far as what we would have to do to install everything and what does a database team need to learn. But this was back on 2008 Core and it wasn’t very good.

Richie Rump: Yeah.

Tara Kizer: Yeah, so we abandoned it and I’m sure that company is now using Windows Core because we really wanted to get to that to do Microsoft patching because there’s a lot less to patch on Windows Core than there is on the full versions.

Richie Rump: Yeah, same thing here. Where I was at a company and they were testing it. The IT folks really wanted to go Core and the DBAs were like, “Whoa, wait a second. I don’t know how to handle some of this stuff.’” They tested it and they were like, “Maybe not.” So, they abandoned it.

Tara Kizer: Was it Windows 2008 Core where it first was released?

Brent Ozar: Yeah, I think so.

Tara Kizer: Yeah. It was terrible. We were researching how to set like lock pages in memory via code. All of these things that you have to do on the database server when you need to set up a SQL Server. Once it’s there, you probably have some PowerShell stuff. But back then, it was just painful. I mean we figured it all out, but we decided we just didn’t want to support it yet so we were waiting for Windows 2012 Core.

Brent Ozar: If I remember right on 2008 Core you also had to enable TCP/IP through the SQL Server configuration manager. And even that [inaudible 00:25:39] goes through the GUI so.

Tara Kizer: Yeah.

 

Do we have to pay for the First Responder Kit?

Brent Ozar: Anker says, “Hi, I love using your scripts from the First Responder Kit. I want to use them in production to get performance recommendations but my manager stopped me in doing so after reading the license agreement of yours. Do we have to buy it from you?” No, it’s totally free. In fact, if you go to firstresponderkit.org it has the open source license on there. When you go to firstrepsonderkit.org go click on the GitHub link at the top right. It has a license that’s very normal for open source products. You are free to use it in any capacity that you want to use it as long as you keep that copyright in there. If you try to for example bundle it into a paid product and you don’t include that node of where it came from, then it gets a little sketchy but you can use it for—if you want to take over the world with SQL Server using Service Broker and linked servers, whatever you want to use it for, go knock yourself out.

 

How do I grant access to stored procedures for low-privilege users?

Brent Ozar: Nate says—this will be the last one that we take because he says, as soon as I see a question that says, “I don’t know if you have time left,” that means I probably should have read it before I do it. It says, “When I was a young boy…” He says, no, “If I had a stored proc that needs to be executed with a low level user but requires higher permissions and I don’t want to get the low level user…” He wants to give people access to run stored procedures but they need to be peons. What does he need to do? If you go to BrentOzar.com/AskBrent, that sounds like it’s an advice column. It’s not, it’s about a stored procedure but it has a little instruction on there on how you use certificates in order to grant permissions to users to run stuff. Really simple. Sounds horrifying but it’s super simple. That certificate word sounds awful.

Erik Darling: We’re probably going to change that URL at some point now, huh?

Brent Ozar: At some point I need to move all the rest of the documentation over there because people are going to go, “What do you mean Ask Brent? That doesn’t make any sense.”

Erik Darling: Yeah. Which one?

[Laughter]

Brent Ozar: You changed your name on here too now.

Erik Darling: I did, magic.

Brent Ozar: Oh my goodness. Wow. We look professional. Well thanks everybody for hanging out with us. We’ll see you guys next week at Office Hours. Bye, everybody.

Erik Darling: Bye-bye.

    thank you

  • Thanks for the transcript… I don’t get to make it to the live sessions nearly often enough.

  • In reference to the “DBA who granted the rights on the service accounts to an endpoint” – if you set up an Availability Group in SSMS the hadr_endpoint is created and owned by the logged in user, you can change that via TSQL:

    ALTER AUTHORIZATION ON AVAILABILITY GROUP::[AG_name_here] TO [sa];
    ALTER AUTHORIZATION ON ENDPOINT::[Hadr_endpoint] TO [sa];
