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.

    Massive Number of Users Login Concurrently

    Dear All,

    I have been using alpha product for 2-3 years by now, in those years i have made many applications by it but never made applications that the users login simultaneously in massive numbers.

    But 3 months ago i made an attendance system the users is around 2.600 and usually they are login around maybe 30-50% concurrently, everytime its happens the alpha anywhere server seems could not handle it. and the app become so slow in response . Is there any solutions to handle this kind of problem.

    Please enlighten this padawan oh great jedi masters ,

    Hary

    Re: Massive Number of Users Login Concurrently

    You need additional instances of the server, and a load balancer. That's the bottom line. I'm sure this thread will draw more responses, but a single instance of an Alpha server (or most any web server) is going to have a problem with a peak load like that.

    With a bit of searching, you'll find other threads about this kind of issue on the message board.

      Re: Massive Number of Users Login Concurrently

      Thank you Steve, infact i did a bit of browsing before i posted and found this http://www.alphasoftware.com/alphafo...ight=concurent i know it is a bit hard to measure the right configuration and i just made 2 more instance to accomodate those users, the hardest part for me is that i have to make a unique mobile app apk for each of the instance (it is a mobile app project btw) such as mobile_app1.apk go to instance1 port 80, mobile_app2.apk go to instance 2 port 8080 and so on because this project kinda low on budget i can only get one app server for now and it is taken around 15-25% cpu resources per instance , i am just wondering if its the right approach im doing here lol i am sorry for my lack of knowledge.

          Agree, IIS is the way to go, we are having good success with IIS and the scalability it provides.
          But it still comes down to the server horsepower, You may want to talk to Zebra Host or another ISP as sounds like you need a VPS that you can scale up and down on demand.

              Re: Massive Number of Users Login Concurrently

              Why do you think Alpha with IIS will provide more scalability? How many more concurrent users will you expect to get using Alpha with IIS than with Alpha alone?

                Scalabiliity, load balance serverfarm why else would A5 build a iis product, with the only remark it toke them 5 years and know the road map is heading node.js in terms of time ofcourse (reference Selwyn roadmap)

                BTW nice debate

                  Re: Massive Number of Users Login Concurrently

                  But why is that any different than Alpha without IIS on a load balancer? Again, what benefit do you think running Alpha with IIS will bring?

                  For example, if Alpha without IIS allows 50 or so users at the same time, how many will Alpha with IIS allow at the same time?

                    Steve as i respect u we know each other for a long time but i think u should not leave that upto me in person ask AA not to me directly, ask them the reason for building a IIS server add-on product, let AA answer we do not have to defend as developers we simple use the product in it's best way, what is offered and available!

                      Eric - have you used the Alpha IIS? Do you have experience with it? If so, does it somehow have more speed or capacity per instance?

                        Steve i was one of the early stage beta users years ago, what i remember is caching performace ( typical iis), now the product has been involved, reverse question why should AA spend so many years, invest cost etc in a product, with the exception i can't explain why it toke so long, ask Selwyn.


                        So best option is to test yourself and find out, best regards

                          I fully expect that Alpha Software did this for good reasons. I'm not questioning any of that, or wondering about why it took so long.

                          But what's really hard to come by is anyone's objective measures of a performance under load, and even better, compared with the "regular" Alpha web server. Do you have any of this, or know someone who does?

                          I have a couple customers where we're hoping IIS is the solution to current or expected load issues. But how much better is it?

                            Steve u should ask that question at the forum by general, some people say they have positive results using AA IIS in practice Beta
