Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

  • How does one gauge application size and appropriate server resources?

    Just curious,

    How can I get a gauge of what my application size is and how much server power I will need? Is there a magic ratio, say if my application is certain size then it would need so much CPU/Ram capacity?

    For example, Zebrahost has pricing based on a range from Development to Large Applications - but how do figure out where my application falls within that range?

    My application is around 30 mbs and growing. I've noticed some of my grids are running a little slow but I don't know if I need to give the server more power or if my database, which is run on Amazon's RDS needs more bandwidth/memory.

    By the way, I must comment that I am extremely happy with Zebrahost. They are always very responsive and quick to help resolve problems. Kudos to them!

    Re: How does one gauge application size and appropriate server resources?

    Total size of your application is nearly irrelevant to its performance. If your grid is slow, it's due to the design of your grid. Nobody can really help you here without some more analysis of your application. You should be running at least 4GB of RAM, and 6GB if your SQL database engine is on the same machine as your web server. "More power" doesn't really make sense in any context here. But appropriate RAM and design consideration are probably what you're after.

    And reading your message leaves me confused: are you at Zebrahost, or Amazon?

      Steve,

      Can you tell I'm a newbie - "more power"?

      I have my V12 application server running on Zebrahost but my MySQL database is running on Amazon RDS. I noticed a big improvement in my charts when I move my database to a different server.

      I've got 2048 RAM on the server so that is half what you mentioned. I may look at increasing it.

      I have one grid that is a very simple grid with 6 columns that takes 10-20 seconds to load when I select '100' from the records per page selector. I watched my server monitor and the CPU usage jumped to 100% and did not drop until the grid came back with the resulting 100 records per page.

      The underlying table/view has about 1200 records, not that many in my opinion...

      Just curious

        I think you already know the answer(s).

        More RAM would help - that's one of the reason your db on another server helps.

        100 records in a grid is heavy, and if you're doing mobile, even worse. Grids have long been the workhorse, but the UX and especially its new tools such as the List Control are often preferred, but everything depends on a complete set of specs and I only know what you describe here.

          Hi Jose,
          I am surprise with your way of splitting the WAS & SQL
          from my casual testing at home & office, having SQL reside away from server
          is a real problem & never satisfy me in speed.

          Yes, there is a heavy price to pay when sql server reside on the WAS & takes up all them RAM
          from time to time.

            Many times memory is not a problem if using Sql Server express editions because they can use just 1 gb memory but if you run many instances in same server then you need 1 gb per running Sql Server express instance.

              SQL Server Express is nice, and it's free, but it's not optimum. Instead, host with Zebrahost or Webjogger, and subscribe to their SQL Server Web Edition instead. It's cheap --- something like $25/month. And it doesn't have the limitations of Express, esp. the 1 GB memory limit.

                I'm not using SQL Server, I use MySQL and so far I'm really happy with the current setup. When I had the MySQL db running on the same server as WAS I was finding that some of my charts would take too long to load. But when I moved the database to Amazon the charts loaded immediately.

                  Yes, but that's because you have 2 GB of RAM, and were trying to run both the Alpha Web App Server and MySQL and the rest of your OS all within that 2 GB of RAM. Now you've effectively increased your RAM by adding another machine (the Amazon machine) and given both the web server and MySQL more room.

                    Steve, you are right. I did not realize until after that increasing the RAM would have made a difference as well. Oh well, I personally like having the WAS and DB on different machines anyway. Personal preference.
