Cost Threshold for Parallelism? A Simple Change to Boost Performance

Many default configuration values built-in to Microsoft SQL Server are just long-standing values expected to be changed by a DBA to fit their current environment’s needs. One of these configs often left unchanged is “Cost Threshold for Parallelism” (CTFP). In short, this determines, based on determined query cost (i.e.. estimated workload of a query plan) it’s availability to execute in parallel with multiple CPU threads. A higher CTFP value limits queries to run parallel unless it’s cost exceed the set value.

Certain queries may be best suited to run on single-core performance, while others would benefit more from parallel multi-core execution. The determination of this is based on many variables, including the physical hardware, type of queries, type of data, and many other things. The good news is that SQL’s Query Optimizer helps makes these decisions by using those queries’ “cost” based on the query plan they execute. Cost is assigned by the cardinality estimator.. more on that later.

Here’s our opportunity to optimize the default CTFP value of 5. The SQL Server algorithm (cardinality estimator) that determines query plan cost changed significantly from SQL Server 2012 to present day SQL Server 2016+. Increasing this value to a higher number will allow the query to run via single-core performance which is generally faster than multi-core performance (referencing the top commercial grade CPUs). The common consensus on almost every SQL tuning website, including Microsoft’s own docs, suggests this value should be increased; common agreement as the value of 20 to 30 being a good starting point. Compare your current query plan execution times, increase CTFP, compare new times, and repeat until the results are most favorable.

Since my future blog posts in this series will become more technical, right now’s a perfect time to get your feet wet. Here’s two different methods you can use to make these changes.

Method 1: T-SQL

Copy/Paste the following T-SQL into a new query Window:

USE [DatabaseName] ; — This database where this will be changed.

EXEC sp_configure ‘show advanced options’ , 1 ; — This enables CTFP to be changed

RECONFIGURE

EXEC sp_configure ‘cost threshold for parallelism’, 20 ; — The CTFP value will be 20 here

RECONFIGURE

Method 2: GUI

To make changes via SQL Server Management Studio:

1. In Object Explorer – Right Click Instance – Properties – Advanced – Under “Parallelism” change value for “Cost Threshold for Parallelism” to 20

2. For changes to take effect, open a query window a run “RECONFIGURE” and execute query.

Keep a look out for my next post which will include queries to help you identify everything I’ve covered in this blog series so far. Any questions, comments, or feedback are appreciated!

Tips and Tricks With MS SQL (Part 9)

Mar 18, 2020 by Sam Taylor

Backups Need Backups

This week I’ve decided to cover something more in the style of a PSA than dealing with configurations and technical quirks that help speed up Microsoft SQL servers. The reason for the change of pace is from what I’ve been observing lately. It’s not pretty.

Backups end up being neglected. I’m not just pointing fingers at the primary backups, but where are the backup’s backups? The issue here is – what happens when the primary backups accidentally get deleted, become corrupt, or the entire disk ends up FUBAR? This happens more often than people realize. A disaster recovery plan that doesn’t have primary backups replicated to an offsite network or the very least in an isolated location is a ticking time bomb.

A healthy practice for the primary backups is to verify the integrity of backups after they complete. You can have Microsoft SQL Server perform checksum validation before writing the backups to media. This way if the checksum value for any page doesn’t exactly match that which is written to the backup, you’ll know the backup is trash. This can be done via scripts, jobs, or via manual backups. Look for the “Media” tab when running a backup task in SQL Server Management Studio. The two boxes to enable are “Verify backup when finished” and “Perform checksum before writing to media”.

It’s true we’re adding extra overhead here and might take backups a bit longer to finish. But I’ll leave it up to you to decide if the extra time is worth having a working backup you can trust to restore your database or a broken backup wasting precious resources. For the sake of reliability, if you decide time is more important, then at least have a script perform these reliability checks on a regular basis or schedule regular restores to make sure they even work.

If you follow this advice you can rest easy knowing your data can survive multiple points of failure before anything is lost. If the server room goes up in flames, you can always restore from the backups offsite. If you need help finding a way to have backup redundancy, a script to test backup integrity, or questions about anything I covered feel free to reach out. Any questions, comments, or feedback are always appreciated! Leave a comment or send me an email to aturika@crossrealms.com for any SQL Server questions you might have!

Plants with Sam: Swiss Cheese Plant

Mar 10, 2020 by Sam Taylor

Hi! Sam here with our latest issue of Plants with Sam, a blog about plants and how to take care of them. I am writing this series to go hand in hand with CrossRealms’ Let’s Grow initiative. My first post with more details can be found here.

Today I would like to talk about the Swiss Cheese Plant – More commonly known as Monstera Deliciosa. This is my favorite plant that I own because they get so big and gorgeous as they mature. It is also known as the Mexican Breadfruit, in reference to its corn cob-shaped fruit (which is said to taste like a combination of pineapple, banana, and mango)

A Monstera’s uniquely shaped leaves allow it to withstand downpours in tropical rainforests. Its structure also helps it take in the few streaks of sunlight that make it to the rain forest floor.

Light

Bright, indirect sunlight is fine for the Swiss Cheese Plant, but harsh sun needs to be avoided as it will scorch and possibly yellow the leaves. Make sure it is getting enough light, otherwise the "Swiss cheese effect" will start to disappear and it will start to produce leaves without holes.

Water

Only moderate levels of watering are required here. When you do water make sure you aim to get all of the compost evenly moist, then wait until it has almost dried out before watering again.

Temperature

Visible new growth will show whenever temperatures are regularly at 65°F or above. Although it will survive easily between 50°F - 86°F try to keep in the middle of this where possible to avoid temperature related problems.

Fertilizer

Feeding is essential if you want new, lush green growth. Use any houseplant feed and use it it at normal strength no more than once a month during periods of active growth. Reduce the amount and frequency of feed if you're finding your plant is becoming a monster and outgrowing its home too fast!

Humidity

It will take average to high humidity levels well, but will start to suffer if things are very dry for prolonged periods. Find ways that work for you to increase humidity if this is likely to be an issue in the spot you have chosen for it.

If you follow these plant care tips, your Monstera will be happy and healthy. Don't forget to stay tuned for more plant care tips!

CVE-2019-19781 – Vulnerability in Citrix Application Delivery Controller

Feb 11, 2020 by Sam Taylor

Description of Problem

A vulnerability has been identified in Citrix Application Delivery Controller (ADC) formerly known as NetScaler ADC and Citrix Gateway formerly known as NetScaler Gateway that, if exploited, could allow an unauthenticated attacker to perform arbitrary code execution.

The scope of this vulnerability includes Citrix ADC and Citrix Gateway Virtual Appliances (VPX) hosted on any of Citrix Hypervisor (formerly XenServer), ESX, Hyper-V, KVM, Azure, AWS, GCP or on a Citrix ADC Service Delivery Appliance (SDX).

Further investigation by Citrix has shown that this issue also affects certain deployments of Citrix SD-WAN, specifically Citrix SD-WAN WANOP edition. Citrix SD-WAN WANOP edition packages Citrix ADC as a load balancer thus resulting in the affected status.

The vulnerability has been assigned the following CVE number:

• CVE-2019-19781 : Vulnerability in Citrix Application Delivery Controller, Citrix Gateway and Citrix SD-WAN WANOP appliance leading to arbitrary code execution

The vulnerability affects the following supported product versions on all supported platforms:

• Citrix ADC and Citrix Gateway version 13.0 all supported builds before 13.0.47.24

• NetScaler ADC and NetScaler Gateway version 12.1 all supported builds before 12.1.55.18

• NetScaler ADC and NetScaler Gateway version 12.0 all supported builds before 12.0.63.13

• NetScaler ADC and NetScaler Gateway version 11.1 all supported builds before 11.1.63.15

• NetScaler ADC and NetScaler Gateway version 10.5 all supported builds before 10.5.70.12

• Citrix SD-WAN WANOP appliance models 4000-WO, 4100-WO, 5000-WO, and 5100-WO all supported software release builds before 10.2.6b and 11.0.3b

What Customers Should Do

Exploits of this issue on unmitigated appliances have been observed in the wild. Citrix strongly urges affected customers to immediately upgrade to a fixed build OR apply the provided mitigation which applies equally to Citrix ADC, Citrix Gateway and Citrix SD-WAN WANOP deployments. Customers who have chosen to immediately apply the mitigation should then upgrade all of their vulnerable appliances to a fixed build of the appliance at their earliest schedule. Subscribe to bulletin alerts at https://support.citrix.com/user/alerts to be notified when the new fixes are available.

The following knowledge base article contains the steps to deploy a responder policy to mitigate the issue in the interim until the system has been updated to a fixed build: CTX267679 – Mitigation steps for CVE-2019-19781

Upon application of the mitigation steps, customers may then verify correctness using the tool published here: CTX269180 – CVE-2019-19781 – Verification Tool

In Citrix ADC and Citrix Gateway Release “12.1 build 50.28”, an issue exists that affects responder and rewrite policies causing them not to process the packets that matched policy rules. This issue was resolved in “12.1 build 50.28/31” after which the mitigation steps, if applied, will be effective. However, Citrix recommends that customers using these builds now update to “12.1 build 55.18”, or later, where CVE-2019-19781 issue is already addressed.

Customers on “12.1 build 50.28” who wish to defer updating to “12.1 build 55.18” or later should choose one from the following two options for the mitigation steps to function as intended:

1. Update to the refreshed “12.1 build 50.28/50.31” or later and apply the mitigation steps, OR

2. Apply the mitigation steps towards protecting the management interface as published in CTX267679. This will mitigate attacks, not just on the management interface but on ALL interfaces including Gateway and AAA virtual IPs

Fixed builds have been released across all supported versions of Citrix ADC and Citrix Gateway. Fixed builds have also been released for Citrix SD-WAN WANOP for the applicable appliance models. Citrix strongly recommends that customers install these updates at their earliest schedule. The fixed builds can be downloaded from https://www.citrix.com/downloads/citrix-adc/ and https://www.citrix.com/downloads/citrix-gateway/ and https://www.citrix.com/downloads/citrix-sd-wan/

Customers who have upgraded to fixed builds do not need to retain the mitigation described in CTX267679.

Splunk 2020 Predictions

Jan 7, 2020 by Sam Taylor

Around the turn of each new year, we start to see predictions issued from media experts, analysts and key players in various industries. I love this stuff, particularly predictions around technology, which is driving so much change in our work and personal lives. I know there’s sometimes a temptation to see these predictions as Christmas catalogs of the new toys that will be coming, but I think a better way to view them, especially as a leader in a tech company, is as guides for professional development. Not a catalog, but a curriculum.

We’re undergoing constant transformation — at Splunk, we’re generally tackling several transformations at a time — but too often, organizations view transformation as something external: upgrading infrastructure or shifting to the cloud, installing a new ERP or CRM tool. Sprinkling in some magic AI dust. Or, like a new set of clothes: We’re all dressed up, but still the same people underneath.

I think that misses a key point of transformation; regardless of what tools or technology is involved, a “transformation” doesn’t just change your toolset. It changes the how, and sometimes the why, of your business. It transforms how you operate. It transforms you.

Splunk’s Look at the Year(s) Ahead

That’s what came to mind as I was reading Splunk’s new 2020 Predictions report. This year’s edition balances exciting opportunities with uncomfortable warnings, both of which are necessary for any look into the future.

Filed under “Can’t wait for that”:

5G is probably the most exciting change, and one that will affect many organizations soonest. As the 5G rollouts begin (expect it to be slow and patchy at first), we’ll start to see new devices, new efficiencies and entirely new business models emerge.
Augmented and virtual reality have largely been the domain of the gaming world. However, meaningful and transformative business applications are beginning to take off in medical and industrial settings, as well as in retail. The possibilities for better, more accessible medical care, safer and more reliable industrial operations and currently unimagined retail experiences are spine-tingling. As exciting as the gaming implications are, I think that we’ll see much more impact from the use of AR/VR in business.
Natural language processing is making it easier to apply artificial intelligence to everything from financial risk to the talent recruitment process. As with most technologies, the trick here is in carefully considered application of these advances.

On the “Must watch out for that” side:

Deepfakes are a disturbing development that threaten new levels of fake news, and also challenge CISOs in the fight against social engineering attacks. It’s one thing to be alert to suspicious emails. But when you’re confident that you recognize the voice on the phone or the image in a video, it adds a whole new layer of complexity and misdirection.
Infrastructure attacks: Coming into an election year, there’s an awareness of the dangers of hacking and manipulation, but the vulnerability of critical infrastructure is another issue, one that ransomware attacks only begin to illustrate.

Tools exist to mitigate these threats, from the data-driven technologies that spot digital manipulations or trace the bot armies behind coordinated disinformation attacks to threat intelligence tools like the MITRE ATT&CK framework, which is being adopted by SOCs and security vendors alike. It’s a great example of the power of data and sharing information to improve security for all.

Change With the Times

As a leader trying to drive Splunk forward, I have to look at what’s coming and think, “How will this transform my team? How will we have to change to be successful?” I encourage everyone to think about how the coming technologies will change our lives — and to optimize for likely futures. Business leaders will need greater data literacy and an ability to talk to, and lead, technical team members. IT leaders will continue to need business and communication skills as they procure and manage more technology than they build themselves. We need to learn to manage complex tech tools, rather than be mystified by them, because the human interface will remain crucial.

There are still some leaders who prefer to “trust their gut” rather than be “data-driven.” I always think that this is a false dichotomy. To ignore the evidence of data is foolish, but data generally only informs decisions — it doesn’t usually make them. An algorithm can mine inhuman amounts of data and find patterns. Software can extract that insight and render an elegant, comprehensible visual. The ability to ask the right questions upfront, and decide how to act once the insights surface, will remain human talents. It’s the combination of instinct and data together that will continue to drive the best decisions.

This year’s Splunk Predictions offer several great ways to assess how the future is changing and to inspire thought on how we can change our organizations and ourselves to thrive.

Tips and Tricks with MS SQL (Part 8)

Dec 23, 2019 by Sam Taylor

Tame Your Log Files!

By default, the recovery model for database backups on Microsoft‘s SQL Server is set to “full”. This could cause issues for the uninitiated. If backups aren’t fully understood and managed correctly it could cause log files to bloat in size and get out of control. With the “full” recovery model, you get the advantage of flexibility in point-in-time restores and high-availability scenarios, but this also means having to run separate backups for log files in addition to the data files.

To keep things simple, we’ll look at the “simple” recovery model. When you run backups, you’re only dealing with data backups whether it’s a full or differential backup. The log file, which holds transactions between full backups, won’t be something you need to concern yourself with unless you’re doing advanced disaster recovery, like database mirroring, log shipping, or high-availability setups.

When dealing with a “full” recovery model, you’re not only in charge of backing up the data files, but the log files as well. In a healthy server configuration, log files are much smaller than data files. This means you can run log backups every 15 minutes or every hour without much IO activity as a full or differential backup. This is where you get the point-in-time flexibility. This is also where I often see a lot of issues…

Log files run astray. A new database might be created or migrated, and the default recovery model is still in “full” recovery mode. A server that relies on a simpler setup might not catch this nor have log backups in place. This means the log file will start growing exponentially, towering over the data file size, and creating hordes of VLFs (look out for a future post about these). I’ve seen a lot of administrators not know how to control this and resort to shrinking databases or files – which is just something you should never do unless your intentions are data corruption and breaking things.

My advice here is keep it simple. If you understand how to restore a full backup, differential backups, and log backups including which order they should be restored in and when to use “norecovery” flags, or have third-party software doing this for you, you’re all set. If you don’t, I would suggest setting up log backups to run at regular and short interval (15 mins – 1 hour) as a precaution and changing the database recovery models to “simple”. This can keep you protected when accidentally pulling in a database that defaulted to the “full” recovery model and having its log file eat the entire disk.

Pro Tip: Changing your “model” database’s recovery model will determine the default recovery model used for all new databases you create.

Any questions, comments, or feedback are appreciated! Leave a comment or send me an email to aturika@crossrealms.com for any SQL Server questions you might have!

3CX Phone System on Campus

Dec 23, 2019 by Sam Taylor

Higher Learning at a Lower Cost

Universities are places where ideas can be communicated freely. What better way to do this, than through a unified communications system like 3CX. As the central communications system on-campus, 3CX offers multiple opportunities to encourage and facilitate learning. It can connect staff members and students with benefits for everyone, including free audio/video calls, low-cost external calls, access to all areas, integrations with other used systems, and more. Let’s examine this use case in more detail.

Affordable Communication on a Shoe-string Budget

3CX is the ideal tool for universities that require all the advanced features of a unified communication system, without the hefty price tag. Apart from a PBX server, 3CX requires no additional hardware to be installed, making it easily accessible to your staff. The only requirement is a PC with a modern web browser. This simplifies administration, drastically reduces support requests and is a more cost-effective solution overall. What’s more, 3CX provides built-in support for a multitude of IP phones and SIP devices, making it easy to choose a desk phone or SIP device that suits everyone’s budget.

Keep in Contact, at the Lecture Theatre, Dorm or While Roaming

Add the 3CX Android and iOS apps to the mix, and your staff can talk, chat and access a university-wide shared phonebook/directory from their smartphones – wherever they may be. When calling on the move, the app reconnects calls automatically through available WiFi or 4G networks. They can also use Chat to exchange messages and documents while at the campus or anywhere else. 3CX can really empower you to do more with your devices!

Extend Your Reach to Facilitate Teamwork

Universities can typically span multiple buildings and areas, which makes setting up difficult under a single communications solution. Not so with 3CX, as it can unify all your remote offices and dorms using bridges and SBCs (Session Border Controllers), to allow your personnel and students to communicate, irrespective of their location. Academic staff and students can also use WebMeeting at no extra cost, to join on-line video meetings for study groups, or webinar sessions with teaching assistants, lab technicians, and so on.

Never Alone. Integrate & Automate

Traditionally a phone system functions in isolation, with little or no ability to interface with other university systems and services. On the contrary, 3CX includes built-in integration options with Office 365, databases, CRMs and other network-enabled systems.

As a quick example, consider a 3CX script-based IVR (Interactive Voice Response) menu, that services students’ course enrollment requests. The student calls the IVR, enters the ID for the chosen course and 3CX will deliver the student’s telephone number and course selection to the university’s course management system. What’s more, by using the Call Flow Designer (CFD), you can create call flows to automate your procedures, from course billing to announcements via text-to-speech. And CFD does not require any programming knowledge!

Keep in Control of Access & Security

Universities need to maintain controlled and secure access to areas like offices, labs, and dorms. 3CX supports popular video door phone devices which can be used with 3CX. Through this, you can attend to visitors seeking entry, or even control activity and access to specific areas – doing away with employing costly security personnel. You can also use PA systems connected to 3CX, to perform announcements in university common areas, classrooms and halls.

No Master’s Degree Required to Administer

With 3CX, administrators have freedom of choice! Install with ease on Linux, Windows, Raspberry Pi and on popular cloud providers like Google Cloud, Azure, and AWS. Not only is it easy to install, but easy to manage too. Keep your data safe by securing and managing your backups, recordings and voicemails with flexible options, on local or remote storage (FTP, SSH and SMB). What’s more, administrators can use the built-in Instance Manager to remotely monitor, manage and update a Linux PBX.

In Conclusion

Universities are by definition communities of teachers and scholars. 3CX bridges the communication gap between these communities facilitates learning and strengthens relationships. It is the perfect fit for organizations that value communication as the primary means of education. And it comes with an affordable price tag, to boot!
