  • SQL Server (2012 Enterprise) Browser service failing

    - by Watki02
    SQL Server (2012 Enterprise) Browser service failing I have a problem as described below: I have an instance of SQL Server 2012 Enterprise (thanks to MSDN) for local development on my PC. I try to start SQL server Browser Service from SQL Server Configuration Manager and it takes a long time to fail, then fails with: The request failed or the service did not respond in a timely fashion. Consult the event log or other applicable error logs for details. I checked event logs and found these errors in this order (all within the same 1-second time frame): The SQL Server Browser service port is unavailable for listening, or invalid. The SQL Server Browser service was unable to establish SQL instance and connectivity discovery. The SQL Server Browser is enabling SQL instance and connectivity discovery support. The SQL Server Browser service was unable to establish Analysis Services discovery. The SQL Server Browser service has started. The SQL Server Browser service has shutdown. I checked firewall rules and both port 1433 (TCP) and 1434 (UDP) are wide open, just as well - the programs and service binary had been "allowed through windows firewall". I started the "Analysis Services" service by hand and it works fine. Browser still won't start. Some History: Installed SQL 2008 R2 express advanced Installed SQL2012 Express advanced Uninstalled SQL 2008 R2 express advanced Installed 2012 SSDT and lots of features with Express install Installed a unique instance of SQL 2012 Enterprise with all features Uninstalled SSDT and reinstalled SSDT with Enterprise (solved a different problem) Uninstalled SQL 2012 Express Uninstalled SQL 2012 Enterprise Removed anything with "SQL" in the name from Control panel "Programs and features" Installed SQL 2012 Enterprise without Analysis services (This is where I noticed SQL Browser service was failing to start even on the install) Added the feature of Analysis Services (and everything else) via the installer (Browser continued to fail to start on the install) ======================== Other interesting facts: opening a command window with administrator and trying to run sqlbrowser.exe manually yielded: Microsoft Windows [Version 6.1.7601] Copyright (c) 2009 Microsoft Corporation.

  • AIA - Server Topologien und Deployment

    - by Hans Viehmann
    Es gibt ein neues White Paper, in dem die verschiedenen Varianten von AIA Topologien ausführlich beschrieben sind. Die unterschiedlichen Möglichkeiten ergeben sich vor allem aus dem Betrieb mehrerer AIA Instanzen parallel (z.B. Aufteilung in Dev/Test/Prod, Aufteilung zur Lastverteilung, Zuordnung zu unterschiedlichen Geografien, ...). Weitere Variationsmöglichkeiten bietet die Verteilung der unterschiedlichen Bestandteile des DB-Schemas (AIA Metadaten, Cross-Referencing Daten, AIA Lifecycle Repository, JMS Schema, etc.). Und schließlich können auch verschiedene Topologien der SOA Laufzeitumgebung, wie beispielsweise SOA Cluster, unterstützt werden. Diese Varianten mit ihren typischen Einsatzfeldern werden in dem Dokument ebenso beschrieben, wie deren Umsetzung mit Hilfe des Installers.In einem zweiten Teil befasst sich das White Paper mit dem Deployment der AIA Artefakte in diese Topologien, und zwar insbesondere mit dem Tool-Support durch die "Project Lifecycle Workbench" und dem "AIA Installation Driver". Erstere ist eine neue Komponente in AIA 11gR1, die in der Lage ist, am Ende des Entwicklungszyklus Deployment Pläne zu generieren, während der ebenfalls neue "AIA Installation Driver" dann die Artefakte dann in die Zielumgebung überträgt.Das White Paper ist noch nicht auf oracle.com verfügbar und ist leider so umfangreich, dass es nicht auf auf blogs.oracle.com hochgeladen werden kann. Bei Interesse verschicke ich es aber gern per Mail.

  • Scrambling Sensitive Data in E-Business Suite Release 12 Cloned Environments

    - by Elke Phelps (Oracle Development)
    Securing the Oracle E-Business Suite includes protecting the underlying E-Business data in production and non-production databases.  While steps can be taken to provide a secure configuration to limit EBS access, a better approach to protecting non-production data is simply to scramble (mask) the data in the non-production copy.  You can use the Oracle Data Masking Pack with Oracle Enterprise Manager today to scramble sensitive data in cloned environments. Due to data dependencies, scrambling E-Business Suite data is not a trivial task.  The data needs to be scrubbed in such a way that allows the application to continue to function.  Using the Data Masking Pack in E-Business Suite environments is now easier with the release of new set of templates for E-Business Suite databases: Oracle E-Business Suite Release 12.1.3 Template for Data Masking Pack (Patch13898999) This template works with the Oracle Data Masking Pack and Oracle Enterprise Manager to obscure sensitive E-Business Suite information that is copied from production to non-production environments.  Is there a charge for this? Yes. You must purchase licenses for Oracle Enterprise Manager and the Oracle Data Masking Pack plug-in. The Oracle E-Business Suite 12.1.3 Template for the Data Masking Pack is included with the Oracle Data Masking Pack license.  You can contact your Oracle account manager for more details about licensing. What does data masking do in E-Business Suite environments? Application data masking does the following: De-identify the data:  Scramble identifiers of individuals, also known as personally identifiable information or PII.  Examples include information such as name, account, address, location, and driver's license number. Mask sensitive data:  Mask data that, if associated with personally identifiable information (PII), would cause privacy concerns.  Examples include compensation, health and employment information.   Maintain data validity:  Provide a fully functional application. How can EBS customers use data masking? The Oracle E-Business Suite Template for Data Masking Pack can be used in situations where confidential or regulated data needs to be shared with other non-production users who need access to some of the original data, but not necessarily every table.  Examples of non-production users include internal application developers or external business partners such as offshore testing companies, suppliers or customers.  The Oracle E-Business Suite Template for Data Masking Pack is applied to a non-production environment with the Enterprise Manager Grid Control Data Masking Pack.  When applied, the Oracle E-Business Suite Template for Data Masking Pack will create an irreversibly scrambled version of your production database for development and testing.   References For additional information on the Oracle E-Business Suite Template for Data Masking Pack please refer to the following: Masking Sensitive Data for Non-production Use in the Oracle Enterprise Manager Concepts 11g Using the Oracle E-Business Suite, Release 12.1.3 Template for the Data Masking Pack, Note 1437485.1 Related Articles Webcast Replay Available: E-Business Suite Data Protection Oracle E-Business Suite Plug-in 4.0 Released for OEM 11g (11.1.0.1)

  • Five Ways Enterprise 2.0 Can Transform Your Business - Q&A from the Webcast

    - by [email protected]
    A few weeks ago, Vince Casarez and I presented with KMWorld on the Five Ways Enterprise 2.0 Can Transform Your Business. It was an enjoyable, interactive webcast in which Vince and I discussed the ways Enterprise 2.0 can transform your business and more importantly, highlighted key customer examples of how to do so. If you missed the webcast, you can catch a replay here. We had a lot of audience participation in some of the polls we conducted and in the Q&A session. We weren't able to address all of the questions during the broadcast, so we attempted to answer them here: Q: Which area within your firm focuses on Web 2.0? Meaning, do you find new departments developing just to manage the web 2.0 (Twitter, Facebook, etc.) user experience or are you structuring current departments? A: There are three distinct efforts within Oracle. The first is around delivery of these Web 2.0 services for enterprise deployments. This is the focus of the WebCenter team. The second effort is injecting these Web 2.0 services into use cases that drive the different enterprise applications. This effort is focused on how to manage these external services and bring them into a cohesive flow for marketing programs, customer care, and purchasing. The third effort is how we consume these services internally to enhance Oracle's business delivery. It leverages the technologies and use cases of the first two but also pushes the envelope with regards to future directions of these other two areas. Q: In a business, Web 2.0 is mostly like action logs. How can we leverage the official process practice versus the logs of a recent action? Example: a system configuration modified last night on a call out versus the official practice that everybody would use in the morning.A: The key thing to remember is that most Web 2.0 actions / activity streams today are based on collaboration and communication type actions. At least with public social sites like Facebook and Twitter. What we're delivering as part of the WebCenter Suite are not just these types of activities but also enterprise application activities. These enterprise application activities come from different application modules: purchasing, HR, order entry, sales opportunity, etc. The actions within these systems are normally tied to a business object or process: purchase order/customer, employee or department, customer and supplier, customer and product, respectively. Therefore, the activities or "logs" as you name them are able to be "typed" so that as a viewer, you can filter or decide to see only certain types of information. In your example, you could have a view that only showed you recent "configuration" changes and this could be right next to a view that showed off the items to be watched every morning. Q: It's great to hear about customers using the software but is there any plan for future webinars to show what the products/installs look like? That would be very helpful.A: We don't have a webinar planned to show off the install process. However, we have a viewlet that's posted on Oracle Technology Network. You can see it here:http://www.oracle.com/technetwork/testcontent/wcs-install-098014.htmlAnd we've got excellent documentation that walks you through the steps here:http://download.oracle.com/docs/cd/E14571_01/install.1111/e12001/install.htmAnd there's a whole set of demos and examples of what WebCenter can do at this URL:http://www.oracle.com/technetwork/middleware/webcenter/release11-demos-097468.html Q: How do you anticipate managing metadata across the enterprise to make content findable?A: We need to first make sure we are all talking about the same thing when we use a word like "metadata". Here's why...  For a developer, metadata means information that describes key elements of the portal or application and what the portal or application can do. For content systems, metadata means key terms that provide a taxonomy or folksonomy about the information that is being indexed, ordered, and managed. For business intelligence systems, metadata means key terms that provide labels to groups of data that most non-mathematicians need to understand. And for SOA, metadata means labels for parts of the processes that business owners should understand that connect development terminology. There are also additional requirements for metadata to be available to the team building these new solutions as well as requirements to make this metadata available to the running system. These requirements are often separated by "design time" and "run time" respectively. So clearly, a general goal of managing metadata across the enterprise is very challenging. We've invested a huge amount of resources around Oracle Metadata Services (MDS) to be able to provide a more generic system for all of these elements. No other vendor has anything like this technology foundation in their products. This provides a huge benefit to our customers as they will now be able to find content, processes, people, and information from a common set of search interfaces with consistent enterprise wide results. Q: Can you give your definition of terms as to document and content, please?A: Content applies to a broad category of information from Word documents, presentations and reports through attachments to invoices and/or purchase orders. Content is essentially any type of digital asset including images, video, and voice. A document is just one type of content. Q: Do you have special integration tools to realize an interaction between UCM and WebCenter Spaces/Services?A: Yes, we've dedicated a whole team of engineers to exploit the key features of Oracle UCM within WebCenter.  While ensuring that WebCenter can connect to other non-Oracle systems, we've made sure that with the combined set of Oracle technology, no other solution can match the combined power and integration.  This is part of the Oracle Fusion Middleware strategy which is to provide best in class capabilities for Content and Portals.  When combined together, the synergy between the two products enables users to quickly add capabilities when they are needed.  For example, simple document sharing is part of the combined product offering, but if legal discovery or archiving is required, Oracle UCM product includes these capabilities that can be quickly added.  There's no need to move content around or add another system to support this, it's just a feature that gets turned on within Oracle UCM. Q: All customers have some interaction with their applications and have many older versions, how do you see some of these new Enterprise 2.0 capabilities adding value to existing enterprise application deployments?A: Just as Service Oriented Architectures allowed for connecting the processes of different applications systems to work together, there's a need for a similar approach with regards to these enterprise 2.0 capabilities. Oracle WebCenter is built on a core architecture that allows for SOA of these Enterprise 2.0 services so that one set of scalable services can be used and integrated directly into any type of application. In this way, users can get immediate value out of the Enterprise 2.0 capabilities without having to wait for the next major release or upgrade. These centrally managed WebCenter services expose a set of standard interfaces that make it extremely easy to add them into existing applications no matter what technology the application has been implemented. Q: We've heard about Oracle Next Generation applications called "Fusion Applications", can you tell me how all this works together?A: Oracle WebCenter powers the core collaboration and social computing services found within Fusion Applications. It is the core user experience technology for how all the application screens have been implemented. And the core concept of task flows allows for all the Fusion Applications modules to be adaptable and composable by business users and IT without needing to be a professional developer. Oracle WebCenter is at the heart of the new Fusion Applications. In addition, the same patterns and technologies are now being added to the existing applications including JD Edwards, Siebel, Peoplesoft, and eBusiness Suite. The core technology enables all these customers to have a much smoother upgrade path to Fusion Applications. They get immediate benefits of injecting new user interactions into their existing applications without having to completely move to Fusion Applications. And then when the time comes, their users will already be well versed in how the new capabilities work. Q: Does any of this work with non Oracle software? Other databases? Other application servers? etc.A: We have made sure that Oracle WebCenter delivers the broadest set of development choices so that no matter what technology you developers are using, WebCenter capabilities can be quickly and easily added to the site or application. In addition, we have certified Oracle WebCenter to run against non-Oracle databases like DB2 and SQLServer. We have stated plans for certification against MySQL as well. Later in CY 2011, Oracle will provide certification on non-Oracle application servers such as WebSphere and JBoss. Q: How do we balance User and IT requirements in regards to Enterprise 2.0 technologies?A: Wrong decisions are often made because employee knowledge is not tapped efficiently and opportunities to innovate are often missed because the right people do not work together. Collaboration amongst workers in the right business context is critical for success. While standalone Enterprise 2.0 technologies can improve collaboration for collaboration's sake, using social collaboration tools in the context of business applications and processes will improve business responsiveness and lead companies to a more competitive position. As these systems become more mission critical it is essential that they maintain the highest level of performance and availability while scaling to support larger communities. Q: What are the ways in which Enterprise 2.0 can improve business responsiveness?A: With a wide range of Enterprise 2.0 tools in the marketplace, CIOs need to deploy solutions that will meet the requirements from users as well as address the requirements from IT. Workers want a next-generation user experience that is personalized and aggregates their daily tools and tasks, while IT needs to ensure the solution is secure, scalable, flexible, reliable and easily integrated with existing systems. An open and integrated approach to deploying portals, content management, and collaboration can enhance your business by addressing both the needs of knowledge workers for better information and the IT mandate to conserve resources by simplifying, consolidating and centralizing infrastructure and administration.

  • Hyper-V virtual machine unable to get IP address from DHCP server running on same physical box

    - by Bronumski
    We have a Windows server 2008 R2 with two network cards running AD, DHCP, DNS and Hyper-V The first nic is setup with a static IP address and DHCP, WDS, and DNS are bound to it. The second nic is configured in Hyper-V to be only used by Hyper-V and has been automatically configured so that only the virtual switch is enabled on the adapter. DHCP and DNS work fine for all physical machines on the network. It also works for Virtual Machines running on another physical box. Virtual machines that are bound to the virtual switch network adapter are unable to get a IP address. If the virtual machine is given a static IP address with correct subnet, gateway and dns everything works. Has anyone else got this working?

  • Windows Server 2008 R2 DNS Server not working?

    - by wolfvilleian
    Hi, I have a server running Windows Server 2008 R2 hosting a DNS server, exchange 2010 and is a domain controller. One computer on the network (and domain) can ping the server 25% of the time, also when I try to ping it's own hostname it also does not work. However another computer that is on the domain can ping it fine, and another computer on the network but not domain can ping fine as well. The computer that cannot ping the server is setup to use the DNS server running on the server only (secondary dns points to nothing) and it will resolve the hostname of the server to the external IP not internal when the other two computers correctly resolve the internal All 3 computers and server are connected directly into the same switch. Does anyone have any ideas on how to fix this? Thanks

  • Anybody seen this behavior with Sql Server Reporting Services, a 64bit OS and an Oracle datasource?

    - by dkackman
    I'm working on a Sql Server Reporting Services solution that queries across both a Sql Server data source and an Oracle 10g data source. My dev box is Windows 7 64bit with Sql Server 2008R2 and I'm hosting IIS7 and SSRS on that system for development; using VS.NET for designing the reports. I have been having errors when running the report where SSRS complains about loading the 32 bit Oracle client in a 64bit process. There a number of threads out there about how to solve that. The thing is, they all come down to making sure you have the 64bit Oracle, client which I do. The weird chain of events I have goes like this: Create initial Oracle datasource and wire up report (it works) Edit Oracle datasource connection (it stops working with BadImageFormatException 32bit/64bit error message) uninstall and reinstall Oracle client (it works) Edit Oracle connection again (it stops working with BadImageFormatException 32bit/64bit error message) So short of reinstalling the client every time I change the connection string I am at a complete loss. Has anybody seen this sort of behavior? And if so what the heck am I doing wrong?

  • Archive log transfer from Oracle 9i to Oracle 10g

    - by Jamie Love
    Hi all, I have a situation where I need to transfer Oracle 9i archive logs to an Oracle 10g database, from where they are to be mined by a log-miner and then used by an Oracle streams capture/apply processes. (Oracle 9 archive logs can be read by the Oracle 10 logminer - I can manually copy the archive logs across, manually register them and have them mined, captured then applied). The difficulty is that the way Oracle does archive log transfer changed quite a bit between 9i and 10g and setting up the 9i database to transfer to the remote machine like so: log_archive_dest_state_2 = enable log_archive_dest_2 = "service=OTHERMACHINE arch optional" no longer works. I get this in the 9i logs: *** 2009-05-22 04:03:44.149 RFS network connection lost at host 'OTHERMACHINE' Error 3113 attaching RFS server to standby instance at host 'OTHERMACHINE' Error 3113 attaching to destination LOG_ARCHIVE_DEST_2 standby host 'OTHERMACHINE' Heartbeat failed to connect to standby 'OTHERMACHINE'. Error is 3113. *** 2009-05-22 04:03:44.150 kcrrfail: dest:2 err:3113 force:0 ORA-03113: end-of-file on communication channel And in the 10g log I get: Fri May 22 04:07:42 2009 WARNING: inbound connection timed out (ORA-3136) My question is: Does anyone know how I could configure my 9i or 10g server such that the 10g server will accept the 9i connection in such a way that I can transfer the 9i archive logs to the 10g server. It would be a bonus if the archive logs would be automatically registered in the 10g server. Note I have not set up a full DataGuard configuration here and the 10g database is not a secondary server. Thanks for any suggestions. Edit Note that I can log on to the 10g server from the 9i server via sqlplus, so connectivity is not the problem Edit 2 After a large amount of time searching for a solution, I've finally decided that such a mechanism doesn't work, and that a non-Oracle method of transferring archive logs from 9i to 10g will need to be used (e.g. rsync).

  • SQL SERVER – SHRINKFILE and TRUNCATE Log File in SQL Server 2008

    - by pinaldave
    Note: Please read the complete post before taking any actions. This blog post would discuss SHRINKFILE and TRUNCATE Log File. The script mentioned in the email received from reader contains the following questionable code: “Hi Pinal, If you could remember, I and my manager met you at TechEd in Bangalore. We just upgraded to SQL Server 2008. One of our jobs failed as it was using the following code. The error was: Msg 155, Level 15, State 1, Line 1 ‘TRUNCATE_ONLY’ is not a recognized BACKUP option. The code was: DBCC SHRINKFILE(TestDBLog, 1) BACKUP LOG TestDB WITH TRUNCATE_ONLY DBCC SHRINKFILE(TestDBLog, 1) GO I have modified that code to subsequent code and it works fine. But, are there other suggestions you have at the moment? USE [master] GO ALTER DATABASE [TestDb] SET RECOVERY SIMPLE WITH NO_WAIT DBCC SHRINKFILE(TestDbLog, 1) ALTER DATABASE [TestDb] SET RECOVERY FULL WITH NO_WAIT GO Configuration of our server and system is as follows: [Removed not relevant data]“ An email like this that suddenly pops out in early morning is alarming email. Because I am a dead, busy mind, so I had only one min to reply. I wrote down quickly the following note. (As I said, it was a single-minute email so it is not completely accurate). Here is that quick email shared with all of you. “Hi Mr. DBA [removed the name] Thanks for your email. I suggest you stop this practice. There are many issues included here, but I would list two major issues: 1) From the setting database to simple recovery, shrinking the file and once again setting in full recovery, you are in fact losing your valuable log data and will be not able to restore point in time. Not only that, you will also not able to use subsequent log files. 2) Shrinking file or database adds fragmentation. There are a lot of things you can do. First, start taking proper log backup using following command instead of truncating them and losing them frequently. BACKUP LOG [TestDb] TO  DISK = N'C:\Backup\TestDb.bak' GO Remove the code of SHRINKING the file. If you are taking proper log backups, your log file usually (again usually, special cases are excluded) do not grow very big. There are so many things to add here, but you can call me on my [phone number]. Before you call me, I suggest for accuracy you read Paul Randel‘s two posts here and here and Brent Ozar‘s Post here. Kind Regards, Pinal Dave” I guess this post is very much clear to you. Please leave your comments here. As mentioned, this is a very huge subject; I have just touched a tip of the ice-berg and have tried to point to authentic knowledge.

  • What incidentals do server maintenance people/devs need?

    - by SeniorShizzle
    I'm trying to put together a thank-you package for clients who are server-side developers and in charge of their company's servers and databases. Since I've never been in that line of work before, I would like to know what it is like. Get inside your heads, for instance. My first thought was (don't hate me) a few patch cables. I don't know if you guys actually need these often or anything. What are some similar things that you like or need for your lives at work. Small incidentals less than $10 are preferred, like Coffee or a notebook, screwdrivers. Et cetera.

  • overriding new ubuntu installation

    - by tkoomzaaskz
    I've got a ubuntu 11.10 which has lost its support in May 2013, now I'd like to reintall up to the most up-to-date LTS, which is 12.04. My question is regarding my current partitions and doing backups. Is there a safe way to backup my data on some local partitions instead of copying files into DVDs/external drives (this is very uncormortable in my situation). Following are system commands shoing my disk: $ lsblk NAME MAJ:MIN RM SIZE RO MOUNTPOINT sda 8:0 0 232,9G 0 +-sda1 8:1 0 48,8G 0 +-sda2 8:2 0 63G 0 +-sda3 8:3 0 1K 0 +-sda4 8:4 0 53,7G 0 / +-sda5 8:5 0 18,6G 0 +-sda6 8:6 0 25,5G 0 +-sda7 8:7 0 23,3G 0 [SWAP] sr0 11:0 1 1024M 0 and $ sudo fdisk -l [sudo] password for xyz: Disk /dev/sda: 250.1 GB, 250059350016 bytes glowic: 255, sektorów/sciezke: 63, cylindrów: 30401, w sumie sektorów: 488397168 Jednostka = sektorów, czyli 1 * 512 = 512 bajtów Rozmiar sektora (logiczny/fizyczny) w bajtach: 512 / 512 Rozmiar we/wy (minimalny/optymalny) w bajtach: 512 / 512 Identyfikator dysku: 0xc3ffc3ff Device Boot Beginning End Blocks ID System /dev/sda1 * 2048 102402047 51200000 7 HPFS/NTFS/exFAT /dev/sda2 215044096 347080703 66018304 7 HPFS/NTFS/exFAT /dev/sda3 347082750 488392064 70654657+ 5 Extended /dev/sda4 102402048 215042047 56320000 83 Linux /dev/sda5 395905923 434975939 19535008+ 83 Linux /dev/sda6 434976003 488392064 26708031 83 Linux /dev/sda7 347082752 395905023 24411136 82 Linux swap / Solaris In the beginning I had Windows Vista pre-installed with the machine when it was bought (damn!) and I installed linux (the one I have now). The windows-program in master boot record has been overriden by grub and now I can boot with both Windows and Linux. This is list of mounted devices: $ mount /dev/sda4 on / type ext4 (rw,errors=remount-ro,commit=0) proc on /proc type proc (rw,noexec,nosuid,nodev) sysfs on /sys type sysfs (rw,noexec,nosuid,nodev) fusectl on /sys/fs/fuse/connections type fusectl (rw) none on /sys/kernel/debug type debugfs (rw) none on /sys/kernel/security type securityfs (rw) udev on /dev type devtmpfs (rw,mode=0755) devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620) tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755) none on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880) none on /run/shm type tmpfs (rw,nosuid,nodev) binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev) gvfs-fuse-daemon on /home/tomasz/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=tomasz) It's strange (I don't remember such thing) that my current linux uses only one partition (/dev/sda4). But, anyway, it seems like that. My final question is: am I able to use one of the existing linux partitions for a backup and install ubuntu 12.04 without removing neither windows nor ubuntu 11.04? I mean - will grub automatically accept both old windows vista and 2 linuxes (old 11.10 and "new" 12.04)? Is there any hidden operation done while installation that could harm my custom-backup-partition while installing? my fstab file: proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sda4 during installation UUID=d44e89f5-9da2-48eb-83b3-887652ec95d2 / ext4 errors=remount-ro 0 1 # swap was on /dev/sda7 during installation UUID=bbe50535-ba57-434a-9272-211d859f0e00 none swap sw 0 0 sda5 and sda6 are trash partitions created during unsuccessful linux installation (this was linux installation before my current installation), I didn't delete these partitions, but I have access to them (and I can use them as backup partitions). edit: second question is: why does lsblk show /dev/sda having 232,9G while fdisk shows that it has 250.1GB? Where does the difference come from?

  • SQL Server – Learning SQL Server Performance: Indexing Basics – Interview of Vinod Kumar by Pinal Dave

    - by pinaldave
    Recently I just wrote a blog post on about Learning SQL Server Performance: Indexing Basics and I received lots of request that if we can share some insight into the course. Every single time when Performance is discussed, Indexes are mentioned along with it. In recent times, data and application complexity is continuously growing.  The demand for faster query response, performance, and scalability by organizations is increasing and developers and DBAs need to now write efficient code to achieve this. When we developed the course – we made sure that this course remains practical and demo heavy instead of just theories on this subject. Vinod Kumar and myself we often thought about this and realized that practical understanding of the indexes is very important. One can not master every single aspects of the index. However there are some minimum expertise one should gain if performance is one of the concern. Here is 200 seconds interview of Vinod Kumar I took right after completing the course.

  • Event-based server-gameloop in a server based game

    - by Chris
    I know that this site is full of questions about fixed gameloops and variable gameloops and different types of threading. But I coult find barely nothing that is related to server loops. The server has no screen to draw on. It could just run as fast as possible, but of course this makes no sense. But should it really use single "ticks" and send the updates periodically after each tick and wait for the next "tick" to update its state. Is it applicable to replace the gameloop by multilpe events? Suchs as incoming network traffic or timers? I often heared that a gameloop should be determistic, but does it really matter? For instance, when you play a shooter game against humand players and/or AI you proably would never be ably to repeat the same input twice. Is it a good idea to lose determistic behavior if it is nearly impossible to reprodruce the same input twice? So this question is more or less about whether an strictly event-based gameloop is adviseable or not and what are the pros and cons. I could imagene that an event-based gameloop could perform much faster and smoother, since you don't have bug CPU-spikes during the beginning of a new "tick". The fact that I could not find much about an event-based gameloop for servers leads me to the conclusion that inefficient or too complicated to get a real benefit from it. I'm sure if this is enough to get an idea from what I'm interessted to know, but I hope so.

  • SQL SERVER – How to an Add Identity Column to Table in SQL Server

    - by Pinal Dave
    Here is the question I received on SQLAuthority Fan Page. “How do I add an identity column to Table in SQL Server? “ Sometime the questions are very very simple but the answer is not easy to find. Scenario 1: If you are table does not have identity column, you can simply add the identity column by executing following script: ALTER TABLE MyTable ADD ID INT IDENTITY(1,1) NOT NULL Scenario 2: If your table already has a column which you want to convert to identity column, you can’t do that directly. There is a workaround for the same which I have discussed in depth over the article Add or Remove Identity Property on Column. Scenario 3: If your table has already identity column and you can want to add another identity column for any reason – that is not possible. A table can have only one identity column. If you try to have multiple identity column your table, it will give following error. Msg 2744, Level 16, State 2, Line 2 Multiple identity columns specified for table ‘MyTable‘. Only one identity column per table is allowed. Leave a comment if you have any suggestion.

    - by pinaldave
    SQL Server 2012 introduces new analytical functions PERCENT_RANK(). This function returns relative standing of a value within a query result set or partition. It will be very difficult to explain this in words so I’d like to attempt to explain its function through a brief example. Instead of creating a new table, I will be using the AdventureWorks sample database as most developers use that for experiment purposes. Now let’s have fun following query: USE AdventureWorks GO SELECT SalesOrderID, OrderQty, RANK() OVER(ORDER BY SalesOrderID) Rnk, PERCENT_RANK() OVER(ORDER BY SalesOrderID) AS PctDist FROM Sales.SalesOrderDetail WHERE SalesOrderID IN (43670, 43669, 43667, 43663) ORDER BY PctDist DESC GO The above query will give us the following result: Now let us understand the resultset. You will notice that I have also included the RANK() function along with this query. The reason to include RANK() function was as this query is infect uses RANK function and find the relative standing of the query. The formula to find PERCENT_RANK() is as following: PERCENT_RANK() = (RANK() – 1) / (Total Rows – 1) If you want to read more about this function read here. Now let us attempt the same example with PARTITION BY clause USE AdventureWorks GO SELECT SalesOrderID, OrderQty, ProductID, RANK() OVER(PARTITION BY SalesOrderID ORDER BY ProductID ) Rnk, PERCENT_RANK() OVER(PARTITION BY SalesOrderID ORDER BY ProductID ) AS PctDist FROM Sales.SalesOrderDetail s WHERE SalesOrderID IN (43670, 43669, 43667, 43663) ORDER BY PctDist DESC GO Now you will notice that the same logic is followed in follow result set. I have now quick question to you – how many of you know the logic/formula of PERCENT_RANK() before this blog post?
