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.

    Publishing Problem, Anyone Run into This?

    HI,

    Very strange issue, I am perplexed.

    When I publish a file or files (component or .a5w page) to my public web server my website immediately goes down.

    To get the back online I have too physically restart my server (a dedicated Windows server).

    Is this normal? Or can you not publish to a live server?

    Thanks,
    Steve

    You should be able to publish to a live server. I do it all the time. As to why that's happening, I don't know.

      You should be more specific here; "my website goes down" really does not tell anything apart from the fact that you seem to have some kind of problem which you obviously should not have.

        Re: Publishing Problem, Anyone Run into This?

        Your behavior is not normal, but there is one possibility. I assume you are using FTP to publish. When a FTP server sees a file upload coming in, it locks the local copy of the file being uploaded. If that file is needed by the application, the application will appear to freeze until the file is available. Normally, this is momentary and the end user doesn't even notice. But if the upload fails for some reason, and the file is critical, the application can appear to freeze for some period of time.

        We have seen an issue with the Alpha Anywhere internal FTP and a few FTP servers where the FTP upload fails, leaving the file being replaced in the upload in a locked condition. This can be one of the critical files such as the a5_application.a5i file which is used to identify the application and contains data about the application. When this occurs, you will see the FTP progress dialog appear to stop and eventually time out. Unfortunately, if the server is the Windows IIS FTP server, Windows will keep the file in a locked condition for some time. Microsoft does not publish the lock time, but it is often as long as 5 minutes. While the file is locked, the application is not available. When the file finally unlocks, the original file is made available, and the application should run again

        There are a couple message board threads on the issue, such as this one

        http://msgboard.alphasoftware.com/al...l=1#post639082

        We have spend many hours dissecting the process, but have never found a definitive cause. It also doesn't occur with most FTP servers, so it isn't very common. You can publish to a server multiple times, and then the problem can occur for no obvious reason. You can follow the recommendations in the thread message to reduce the chance of this happening.

          Hi Steve,

          I can reliably crash our alpha v11 server with large files, FTP, and impatience. (The project is rather large and only 50% ported to 12 so far.) The issue seems to be that the file is in the middle of being updated - locked probably - and I try to view it. But because it's being used by something, Alpha just flat out crashes. So, I have to log in and start the WAS (it's gone - no crash reports.) The solution in my particular case was to apply a 15 second coffee break between FTP upload & testing. (For the large files --- in excess of 500 KB; the megabyters are particularly problematic.) I should probably include a call to the office to tell everyone not to touch X for 15 seconds --- I don't (YOLO).

          I've never had to physically restart the entire server. I just had to launch the Application Web Server again. Are you having to restart the entire server to get back to a working state? That doesn't seem right.

            It may help to check Publish Selected Only in the publishing profile. That will minimize the number of files being sent. Typically publishing an A5W page does not cause any problem, but if you refresh a component at the same time it is being published, it can lock up. Like others, I publish to a live server all the time if I know it is unlikely someone is refreshing a component or page while I am publishing.

              I wonder if you get the same problem using OPTIMIZED publishing ? That will xfer 1 ZIP file, next the Alpha server will unpack it. That is a different approach compared to FTP'ing file per file.

              EDIT: and MUCH faster!
