  • A case for not installing your own software

    - by James Gentsch
    This week I watched some of the Oracle Open World presentations (from the comfort of my Oracle office) and happened on some of Larry Ellison’s comments about cloud computing and engineered systems.  Larry said he sees the move to these as analogous to the moves made by the original adopters of electricity.  The argument goes that the first consumers of electricity had to set up their own power plant.  Then, as the market and infrastructure for electricity matured, power consumers moved from using their own personal power plant to purchasing power from another entity that was focused on power production as their primary product. In the end this was a cheaper and more reliable solution. Now, there are lots of compelling reasons to be looking very seriously at cloud computing and engineered systems for enterprise application deployment.  However, speaking as a software developer of enterprise applications, the part of this that I really love (besides Larry’s early electricity adopter analogy) is that as a mode of application deployment it provides me and my customers a consistent environment in which the applications I am providing will be run.  This cuts way down on the environmental surprises that consistently lead to the hated “well, it works here” situation with the support desk. And just to be clear, I think I hate this situation more than my clients, who I think are happy that at least it is working somewhere.  I hate this because when a problem happens, and let’s face it customers are not wasting their time calling in easy problems, we are seriously disabled when we cannot reproduce the issue which is triggered by something unforeseen in the environment where the application is running.  This situation is incredibly frustrating and an all too often occurrence. I look selfishly forward to cloud computing and engineered systems dramatically reducing the occurrence of problems triggered by unforeseen environmental situations in the software I am responsible for.  I think this is an evolutionary game changer that will be a huge benefit to the reliability and consistent performance of the software for my customers, and may make “well, it works here” a well forgotten phase for future software developers. It may even impact the stress squeeze toy industry.  Well, maybe at least for my group.

  • Managing Data Growth in SQL Server

    'Help, my database ate my disk drives!'. Many DBAs spend most of their time dealing with variations of the problem of database processes consuming too much disk space. This happens because of errors such as incorrect configurations for recovery models, data growth for large objects and queries that overtax TempDB resources. Rodney describes, with some feeling, the errors that can lead to this sort of crisis for the working DBA, and their solution.

  • Exploring In-memory OLTP Engine (Hekaton) in SQL Server 2014 CTP1

    The continuing drop in the price of memory has made fast in-memory OLTP increasingly viable. SQL Server 2014 allows you to migrate the most-used tables in an existing database to memory-optimised 'Hekaton' technology, but how you balance between disk tables and in-memory tables for optimum performance requires judgement and experiment. What is this technology, and how can you exploit it? Rob Garrison explains.

  • Set and Verify the Retention Value for Change Data Capture

    - by AllenMWhite
    Last summer I set up Change Data Capture for a client to track changes to their application database to apply those changes to their data warehouse. The client had some issues a short while back and felt they needed to increase the retention period from the default 3 days to 5 days. I ran this query to make that change: sp_cdc_change_job @job_type='cleanup', @retention=7200 The value 7200 represents the number of minutes in a period of 5 days. All was well, but they recently asked how they can verify...(read more)

  • Database Maintenance Scripting Done Right

    - by KKline
    I first wrote about useful database maintenance scripts on my SQLBlog account way back in 2008. Hmmm - now that I think about it, I first wrote about my own useful database maintenance scripts in a journal called SQL Server Professional back in the mid-1990's on SQL Server v6.5 or some such. But I digress... Anyway, I pointed out a couple useful sites where you could get some good scripts that would take care of preventative maintenance on your SQL Server, such as index defragmentation, updating...(read more)

  • More than one way to skin an Audit

    - by BuckWoody
    I get asked quite a bit about auditing in SQL Server. By "audit", people mean everything from tracking logins to finding out exactly who ran a particular SELECT statement. In the really early versions of SQL Server, we didn't have a great story for very granular audits, so lots of workarounds were suggested. As time progressed, more and more audit capabilities were added to the product, and in typical database platform fashion, as we added a feature we didn't often take the others away. So now, instead of not having an option to audit actions by users, you might face the opposite problem - too many ways to audit! You can read more about the options you have for tracking users here: http://msdn.microsoft.com/en-us/library/cc280526(v=SQL.100).aspx  In SQL Server 2008, we introduced SQL Server Audit, which uses Extended Events to really get a simple way to implement high-level or granular auditing. You can read more about that here: http://msdn.microsoft.com/en-us/library/dd392015.aspx  As with any feature, you should understand what your needs are first. Auditing isn't "free" in the performance sense, so you need to make sure you're only auditing what you need to. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Can't get into the admin console after migrating to new server

    - by Emerson
    I migrated my WordPress blog to a new server, and everything seemed to be working fine until it started giving me the error when entering the admin area: Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 4864 bytes) in /home/neworder/public_html/blog/wp-admin/includes/plugin.php on line 729 The line 729 has: $protected = array( '_wp_attached_file', '_wp_attachment_metadata', '_wp_old_slug', '_wp_page_template' ); I had installed the maintenance-mode, and I have suspicions that this is what broke the forum. If I remove the plugin it then gives another error: Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 19456 bytes) in /home/neworder/public_html/blog/wp-admin/includes/post.php on line 1158 And that line has: $content .= '<p class="hide-if-no-js">' . esc_html__( 'Remove featured image' ) . '</p>'; } I tried to restore the blog file-system from the old server and also to restore the database from the old server (2x), but still it gives me the same error. The blog itself seems to be working fine: http://blog.antinovaordemmundial.com/

  • High Availability for IaaS, PaaS and SaaS in the Cloud

    - by BuckWoody
    Outages, natural disasters and unforeseen events have proved that even in a distributed architecture, you need to plan for High Availability (HA). In this entry I'll explain a few considerations for HA within Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). In a separate post I'll talk more about Disaster Recovery (DR), since each paradigm has a different way to handle that. Planning for HA in IaaS IaaS involves Virtual Machines - so in effect, an HA strategy here takes on many of the same characteristics as it would on-premises. The primary difference is that the vendor controls the hardware, so you need to verify what they do for things like local redundancy and so on from the hardware perspective. As far as what you can control and plan for, the primary factors fall into three areas: multiple instances, geographical dispersion and task-switching. In almost every cloud vendor I've studied, to ensure your application will be protected by any level of HA, you need to have at least two of the Instances (VM's) running. This makes sense, but you might assume that the vendor just takes care of that for you - they don't. If a single VM goes down (for whatever reason) then the access to it is lost. Depending on multiple factors, you might be able to recover the data, but you should assume that you can't. You should keep a sync to another location (perhaps the vendor's storage system in another geographic datacenter or to a local location) to ensure you can continue to serve your clients. You'll also need to host the same VM's in another geographical location. Everything from a vendor outage to a network path problem could prevent your users from reaching the system, so you need to have multiple locations to handle this. This means that you'll have to figure out how to manage state between the geo's. If the system goes down in the middle of a transaction, you need to figure out what part of the process the system was in, and then re-create or transfer that state to the second set of systems. If you didn't write the software yourself, this is non-trivial. You'll also need a manual or automatic process to detect the failure and re-route the traffic to your secondary location. You could flip a DNS entry (if your application can tolerate that) or invoke another process to alias the first system to the second, such as load-balancing and so on. There are many options, but all of them involve coding the state into the application layer. If you've simply moved a state-ful application to VM's, you may not be able to easily implement an HA solution. Planning for HA in PaaS Implementing HA in PaaS is a bit simpler, since it's built on the concept of stateless applications deployment. Once again, you need at least two copies of each element in the solution (web roles, worker roles, etc.) to remain available in a single datacenter. Also, you need to deploy the application again in a separate geo, but the advantage here is that you could work out a "shared storage" model such that state is auto-balanced across the world. In fact, you don't have to maintain a "DR" site, the alternate location can be live and serving clients, and only take on extra load if the other site is not available. In Windows Azure, you can use the Traffic Manager service top route the requests as a type of auto balancer. Even with these benefits, I recommend a second backup of storage in another geographic location. Storage is inexpensive; and that second copy can be used for not only HA but DR. Planning for HA in SaaS In Software-as-a-Service (such as Office 365, or Hadoop in Windows Azure) You have far less control over the HA solution, although you still maintain the responsibility to ensure you have it. Since each SaaS is different, check with the vendor on the solution for HA - and make sure you understand what they do and what you are responsible for. They may have no HA for that solution, or pin it to a particular geo, or perhaps they have a massive HA built in with automatic load balancing (which is often the case).   All of these options (with the exception of SaaS) involve higher costs for the design. Do not sacrifice reliability for cost - that will always cost you more in the end. Build in the redundancy and HA at the very outset of the project - if you try to tack it on later in the process the business will push back and potentially not implement HA. References: http://www.bing.com/search?q=windows+azure+High+Availability  (each type of implementation is different, so I'm routing you to a search on the topic - look for the "Patterns and Practices" results for the area in Azure you're interested in)

  • Process Improvement and the Data Professional

    - by BuckWoody
    Don’t be afraid of that title – I’m not talking about Six Sigma or anything super-formal here. In many organizations, there are more folks in other IT roles than in the Data Professional area. In other words, there are more developers, system administrators and so on than there are the “DBA” role. That means we often have more to do than the time we need to do it. And, oddly enough, the first thing that is sacrificed is process improvement – the little things we need to do to make the day go faster in the first place. Then we get even more behind, the work piles up and…well, you know all about that. Earlier I challenged you to find 10-30 minutes a day to study. Some folks wrote back and asked “where do I start”? Well, why not be super-efficient and combine that time with learning how to make yourself more efficient? Try out a new scripting language, learn a new tool that automates things or find out ways others have automated their systems. In general, find out what you’re doing and how, and then see if that can be improved. It’s kind of like doing a performance tuning gig on yourself! If you’re pressed for time, look for bite-sized articles (like the ones I’ve done here for PowerShell and SQL Server) that you can follow in a “serial” fashion. In a short time you’ll have a new set of knowledge you can use to make your day faster. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Auto log off windows machine after certain number of minutes

    - by Marty Heath
    I have three machines on my network, two are windows xp and one is windows 7. i would like to have all three machines log a user off if they are on for more than 60 minutes. And I would like this to be applied to the machine not on a per user basis, because I do not want this policy to apply to those users on any other machine. I have installed winexit.scr on one of the machines but the problem is that I cannot change the default value of 10 minutes for the screensaver because that is controlled through group policy, and I cannot seem to find where to change that through group policy on a per machine basis NOT on a per user basis. If I have left out any details I apologize please let me know anything that is needed

  • Quick Tip - Speed a Slow Restore from the Transaction Log

    - by KKline
    Here's a quick tip for you: During some restore operations on Microsoft SQL Server, the transaction log redo step might be taking an unusually long time. Depending somewhat on the version and edition of SQL Server you've installed, you may be able to increase performance by tinkering with the readahead performance for the redo operations. To do this, you should use the MAXTRANSFERSIZE parameter of the RESTORE statement. For example, if you set MAXTRANSFERSIZE=1048576, it'll use 1MB buffers. If you...(read more)

    I am helping out an NGO, called Orphans Found Fund, here in Arusha Tanzania setup a computer lab to teach students about Ubuntu and open source applications. I have installed Ubuntu 10.10 on all the systems. What I'm wondering about is how to tweak the systems so that the kids cannot: Delete or alter system files Alter the system settings Add or remove applications Exceed a time limit (like an Internet Cafe) Also as the administrator I would like to monitor the usage for another system to make sure that abuse of network is not taking place. Any advice is much appreciated. Brendon

  • Preventing Users/Groups from accessing certain Domains

    - by ncphillips
    I have created a Study account which I use when doing anything school related work. It's purpose is to remove the distractions of my normal account, such as social media and news websites. I know /etc/hosts can be edited to block certain domains from being accessed, but this is for all Users, and I don't want to have to switch in and out of Admin to change it every time I want to focus. Is there any way to block these domains for specific Users or Groups?

  • Optimizing Transaction Log Throughput

    As a DBA, it is vital to manage transaction log growth explicitly, rather than let SQL Server auto-growth events "manage" it for you. If you undersize the log, and then let SQL Server auto-grow it in small increments, you'll end up with a very fragmented log. Examples in the article, extracted from SQL Server Transaction Log Management by Tony Davis and Gail Shaw, demonstrate how this can have a significant impact on the performance of any SQL Server operations that need to read the log.

  • svcbundle for easier SMF manifest creation

    - by Glynn Foster
    One of the new features we've introduced in Oracle Solaris 11.1 is a new utility called svcbundle. This utility allows for the easy creation of Service Management Facility (SMF) manifests and profiles, allowing you to take advantage of the benefits of automatic application restart without requiring you to have full knowledge of the XML file format that is used when integrating with the SMF. Integrating into SMF is one of the easiest and most obvious ways to take advantage of some of the mission critical aspects of the operating system, but many customers were often finding the initial learning curve of creating an XML manifest to be too hard. With the release of Oracle Solaris 11 11/11, SMF had a more integral part to play as more and more system configuration was starting to use the SMF configuration repository for the backend storage. This provides a number of aspects, including the ability to carefully manage customized administrative configuration, site specific configuration, and vendor provided configuration at different layers, helping to preserve them during system update. I've written a new article, Using svcbundle to Create SMF Manifests and Profiles in Oracle Solaris 11, to give you a feel for the help we can provide in converting your applications over to SMF, or doing some site wide configuration using profiles. This is the first pass at creating such a tool, so we'd love to hear feedback of your experiences using it.

  • Sys Admins are kind of like gods, aren't they? [closed]

    - by user75798
    A systems administrator has root access to the entire system. There is nothing they cannot do. They are omnipotent. Their power is absolute. Nothing dan stand before them. Like Sauron, the Dark Lord, they do not share power. There can be but one root. Else contradiction at the most fundamental level is possible, and that can not be tolerated. The sys admin's power is unconditional and non-negotiable. To be a sys admin is like being a god. (And if they are a god, what is the religion?) There is an old saying that absolute power corrupts absolutely. I wonder whether being a sys admin has ended up warping an individual. Perhaps a sys admin has become crazed or even gone berserk? Surely sys admins must need to be very level headed people. For example, imagine being 'the' sys admin for the NSA. (What an awesome job that would be!) Think about the access to data, the encryption keys, the secrets... Perhaps one day a sys admin might go bonkers, turn up for work and 'uninstall the entire NSA'! :) But you would have the same sorts of responsibilities working at a bank or other organization. I wonder whether much emphasis is put on ensuring that sys admins are level headed in the first place and kept sweet in the second. Do they get paid well? I am sure they do not receive half of what they are worth, considering all the hard earned knowledge they have had to gain and the massive responsibility they have.
