  • Repeat row headers after Page Break

    - by klaus.fabian
    The lead developer of the FO engine send me by chance an email about a REALLY nice feature I did not know about. Did you ever encounter a long table with merged cells, where the merged cell went on to the next page? While column headers are by default repeated on the next page, row headers are not. Tables with group-left column and pivot tables are prime examples where this problem occurs. I have seen reports where merged cells could go over multiple pages and you would need to back to find the row header on previous pages. The BI Publisher RTF templates have a special tag you can added to a merged cell to repeat the contents after each page break. You just need to add the following (wordy) tag to the next merged table cell: true Example: 2nd page of report before adding the tag 2nd page of report after adding the tag. Thought you might want to know. Klaus

  • Live CD / Live USB much faster than full install

    - by user29347
    I've observed it on both laptops I own! HP Compaq nx6125 and Ubuntu 11.04 x64 - somewhat solved Lenovo Thinkpad T500 and Ubuntu 11.10 x64 - help needed! I'm still struggling with the Thinkpad to get performance level similar to that of 10 y.o. laptops... All in all a really serious issue with multiple versions of Ubuntu that renders computers with perfectly compatible hardware unusable, as far as out of the box experience is concerned. Troubleshooting resultant issues seems to be a hard case even for users with some experience with installing graphics drivers. EDIT: I can't really post additional details. Two different ubuntu versions, two laptops, two different set of graph. drivers (OS vs ATI prop.) - all with the same symptoms. Also I can't stress enough how massive the performance degradation is compared to a healthy system. For that reason I ask for input from people who may know roughly what are we dealing with here. I can post more details if we were to focus on my current Thinkpad T500. In that case my current system details: Lenovo Thinkpad T500 Ubuntu 11.10 x64 ATI Mobility Radeon HD 3650 (also see the "What I have already tried" section about Intel graphics tested) ATI Catalyst 11.10 drivers OCZ Agility 3 SSD but! same with the default driver for ATI the card same with the prop. driver for the ATI card from Jockey (Additional drivers applet) What I have already tried: 0. Switching to Intel integrated card (Intel GMA 4500M HD) with the default driver - same effects = may indicate not driver related problem but a problem with something of global influence like e.g. nomodeset or other I don't even know about. (What you can read above) ATI Catalyst 11.10 and radeon.modeset=0 boot parameter + disabled Wait for VBlank. Unity 2D Ubuntu 10.04 LTS tested (ubuntu-10.04.3-desktop-i386.iso): Both live USB and installed version blazing fast! (on the default drivers - without even installing the proprietary fglrx drivers). re2 a) seems to give me the only significant results (still poor) - perfect Unity elements performance with the same crawling stuttering/lagging when dragging windows around. re2 b) this happens often http://i17.photobucket.com/albums/b68/Bucic/ubuntuforumsorg/Screenshotat2011-10-28083140.png re2 c) Sometimes I am able to witness a normal performance when dragging a window around but only for a second or two. When I try to shake it longer it starts to lag and it will keep lagging like that with an increased probability of what you see in the sshot in point re2 b). re2 d) I can't establish the radeon.modeset=0 influence though. Once it seems to work be smooth with it, the other time - without it. Really can't tell.

  • Programmers and Database Professionals in Performance Based Companies

    - by swisscheese
    Anybody here work for a company (or know of someone that does) in the fields of programming or anything related to DBs and not have set work hours? Where you are paid for performance rather than how many hours you sit in a chair at the office? Any project / company I have been apart of always has pretty strict primary hours with the "great opportunity" / expectation to stay until the job is done. Is this type of flexibility really feasible in a group environment in these fields? Would pay for performance work within a company in these fields? With having strict primary hours I notice a lot of inefficiencies. Some weeks or days there is only so much that can be done (for whatever the reason may be) and if your work is done it doesn't help moral to force someone to stay for 8 hrs/day or 40hrs/week if the next week they may have to pull a 60+hr work week. I know that a lot of flexibility can come from working independently or as a consultant so this question really does not encompass those types of positions.

  • Setting up page goals in Analytics when using progressive enhancement to load content using jquery .load

    - by sam
    I'm using jQuery .load to load content in from other pages into my homepage, so that Google can still see whats going on I've made the <a> tags go to the pages but over ride them in the JavaScript so instead of going the that page it just loads in the content from that page to the main page. Normaly I would just make the page /contact.html a goal. Can I still get it to work as a goal if the content is being loaded in? Can I do something like when the user clicks <a href="contact.html" id="load-contact">contact</a> it logs the clicking of the <a> tag as a goal, rather than the actaul page being visited?

  • Essbase 11.1.2 - AgtSvrConnections Essbase Configuration Setting

    - by Ann Donahue
    AgtSvrConnections is a documented Essbase configuration setting used in conjunction with the AgentThreads and ServerThreads settings. Basically, when a user logs into Essbase, the AgentThreads connects to the ESSBASE process then the AgtSvrConnections will connect the ESSBASE process to the ESSSVR application process which then the ServerThreads are used for end user activities. In Essbase 11.1.2, the default value of the AgtSvrConnections setting was changed to 5. In previous Essbase releases, the AgtSvrConnections setting default value is 1. It is recommended that tuning the AgtSvrConnections settings be done incrementally by 1 or 2 maximum and based on the number of concurrent Set Active/Clear Active calls. In the Essbase DBA Guide and Technical Reference, the maximum setting recommended is to not exceed what is set for AgentThreads, however, we have found that most customers do not need to exceed a setting of 10. In general, it is ok to set AgtSvrConnections close to the AgentThreads setting, however, there have been customers that needed an AgentThread setting greater than 10 and we have found that the AgtSvrConnections setting higher than 5-10 could have a negative impact on Essbase due to too many TCP ports used unnecessarily. As with all Essbase.cfg settings, it is best to set values to what is needed based on process load and not arbitrarily set to high values. In order to monitor and tune the AgtSvrConnections setting, monitor the application log for logins and Set Active/Clear Active messages. If there are a lot of logins and Set Active/Clear Active messages happening in a short period of time making it appear that the login is taking longer, incrementally increase the AgtSvrConnections setting by 1 or 2, which can then help with login speed. The login performance tolerance is different from one customer environment to another since there are other factors that can impact this performance i.e. network latency. What is happening in Essbase when a user logs in: ESSBASE issues a Set Active to the ESSSVR process. Each application has its own ESSSVR process. Set Active then calls MultipleAsyncLogout and waits on the pipe connection. MultipleAsyncLogout goes back to ESSBASE. ESSBASE then needs to send the logout back to the ESSSVR process. When the AgtSvrConnections setting needs to be increased from the default of 5, it is because Essbase cannot find a connection since the previous connections are used by ESSBASE-ESSSVR. In this example, we may want to increase AgtSvrConnections from 5 to 7 to improve the login performance. Again, it is best to set Essbase settings to what is needed based on process load and not arbitrarily set to high values. In general, stress or performance testing environments using automated tools may need higher than normal settings. This is because automated processes run at high speeds for logging in and logging out. Typically, in a real life production environment, the settings are much closer to default values.

  • Organizing ASP.Net Single Page Application with Nancy

    - by OnesimusUnbound
    As a personal project, I'm creating a single page, asp.net web application using Nancy to provide RESTful services to the single page. Due to the complexity of the single page, particularly the JavaScripts used, I've think creating a dedicated project for the client side of web development and another for service side will organize and simplify the development. solution | +-- web / client side (single html page, js, css) | - contains asp.net project, and nancy library | to host the modules in application project folder | +-- application / service (nancy modules, bootstrap for other layer) | . . . and other layers (three tier, domain driven, etc) . Is this a good way of organizing a complex single page application? Am I over-engineering the web app, incurring too much complexity?

  • Performance Tuning with Traces

    - by Tara Kizer
    This past Saturday, I presented "Performance Tuning with Traces" at SQL Saturday #47 in Phoenix, Arizona.  You can download my slide deck and supporting files here. This is the same presentation that I did in September at SQL Saturday #55 in San Diego, however I focused less on my custom server-side trace tool and more on the steps that I take to troubleshoot a production performance problem which often includes server-side tracing.  If any of my blog readers attended the presentation, I'd love to hear your feedback.  I'm specifically interested in hearing constructive criticism.  Speaking in front of people is not something that comes naturally to me.  I plan on presenting in the future, so feedback on how I can do a better job would be very helpful.  My number one problem is I talk too fast!

  • "Popular searches for this page" links with links to the same page, SEO difference?

    - by Rory McCann
    I've seen a few pages that have a section with "Popular searches for this page" and then have the search terms in a link pointing back to the same page (e.g. http://theenglishchillicompany.co.uk/the-complete-chilli-pepper-book-a-gardeners-guide-to-choosing-growing-preserving-and-cooking/) I assume they are doing it for SEO purposes (with more links to the page with the desired search terms). Does this make a difference? It seems strange that a link on page A to page A would be counted! Am I wrong?

  • Does use of simple shaders improve performace/battery life?

    - by Miro
    I'm making OpenGL game for Android. Till now i've used only fixed function pipeline, but i'm rendering simple things. Fixed function pipeline includes a lot of stuff i don't need. So i'm thinking about implementing shaders in my game to simplify OpenGL pipeline if it can make better performance. Better performance = better battery life, unless fps is limited by software limit, not hardware power.

  • Slow gvfs Samba Performance

    - by Wolfgang
    if I use/acces a Samba Share using Nautilus or manually using "gvfs-mount smb://SERVER-IP/Share" I get a poor Performance, only about 7 mb/s on my 100 Mbit Network. If I access the same Share on Windows I get Fullspeed 100 Mbit (About 11 mb/s), also if I mount using sudo mount -t cifs //SERVER-IP/Share /mountpount which uses cifs instead of gvfs I get fullspeed too, so can anyone tell me if there is a Performance Problem/Bug in gvfs or how gvfs is using SMB Shares differerently ? I tested read Perfomance (From my Network Samba Share) with multiples files and always, the cifs-Version is fullspeed and the GVFS-Version has some mb/s less. After some research I found some tips to optimize the Samba Settings of my Ubuntu Installation and some network tuning tips, but as the CIFS mounted share gets the full Network Speed I don't believe its that kind of problem.

    - by Ricardo Ferreira
    Hi folks. This year, together with the Oracle Open World Latin America, happened another edition of the JavaOne Latin America, the more important event of Java for the developers community. I would like to share with you the slides that I've used in my session. The session was "The Future of JVM Performance Tuning" and the idea was to share some knowledge about JVM enhancements that Oracle implemented in Hotspot about performance, specially those ones related with GC ("Garbage Collection") and SDP ("Sockets Direct Protocol"). I hope you enjoy the content :)
