FM8 Performance same if created in FM8 or converted

I recently converted a databease created in FM6 to FM8. Its new, so only has a handful of records (sample data only). I converted it to FM8 and it seems to run slower. I can see the records being "painted" on the sceen.

My question is whether this is because this database was converted from FM6, or would it be the same if the database was created from scratch using FM8?

Probably, because what pulling the teeth out of your solution, is a struggle to make sense of the file references.

Other issues exists though, if you solution is somewhat relation shy, will it probably contain a lot of chained unstored calcfields as well as being splayed with dozens of Summary fields shown elsewhere than dedicated summary reports.

Unfortunately is the reason "paining" that you probably tries to beat filemaker out of the database realm into being a spreadsheet with an interface layer, and the term normalization is what's required.

I'm not quite sure what you mean about me trying to "beat filemaker out of the database realm into being a spreadsheet with an interface layer"..

My system is an order management and inventory system with about 20 files. There are a lot of calculations in the inventory file for caculating inventory balances... but even just displaying a list of orders, FM8 is noticeably slower.

Exactly, databases are for storing data ...you need to take a closer look (... or here listen) at topics like "transaction model"


Or read on here:


Out of curriosity would I like to know what you think the script commands:

Commit Record/Request

Open Record/Request

Revert Record/Request

...as well as the calc'function: GetNextSerialValue ( fileName ; fieldName )

...if it weren't to support a more ACID compliant model?

There have been attampt in this direction with earlier versions:


Which bring up an extra clue, for your debugging process - today should the lookup calc'function be utilized in autoenter fields instead of genuine lookups.

I get the impression you are slapping me but its hard to tell as I don't fully understand why you would ask me what a commit record request is for.

My database stores transactions and also makes calculations based on those transactions.

If you have an order database with transactions (incoming and outgoing stock) how would you determine the current balance of an item without performing calculations?

I realize that all these calculations will slow my system down, if there is a way to avoid using so many calculations, I'd love to hear it.

Hi David,

Do you still have the solution in multiple files or have you consolidated the tables into one file? Calcs should only trigger when called to be displayed, printed or used in a script or other calculation. You might check the file references to see if there are problems resolving the file locations. (file/define/file references)

Also, you might consider the number of fields filemaker is trying to index. This can cause performance issues, because filemaker must build the index for each indexed field when a file is opened.

Did you convert the whole solution together or one file at a time?

      Hello, All!

      I am an aspiring developer for Filemaker. The company I work with is stuck in the past working off of Filemaker Pro 4.1

      I was given the task of bringing us up to Filemaker Pro/Server 13. So far my conversion prototypes are successful but we recently had a layout issue that can only be fixed in versions 3-6 (as the file is an .fp3) I work off of a macbook while our network is all Windows 7. In order for me to repair the layouts without tampering our active database, I decided the best option is to repair a copy of our solutions off the network. Unfortunately, when I go to download the trial version of Filemaker Pro 6 off of the respected website, the file is corrupt! I've tried multiple times, with different extraction apps and in different directories.

      My question is;

      Does anyone know a place where I could obtain version 6 (or better yet, 4.0) for an OSX computer? I've looked everywhere!
      Thank you for your time,
      Tumma K.

      I'm hoping my question can have a happy ending. In the mid-90's, I purchased Filemaker 3. When Filemaker 5.5 Pro was released, I bought the update CD, which requires the user to either have FM 3 installed or to have the installation CD for FM 3. I've used it all these years, most recently with Windows XP Pro, and it has worked just fine. The databases I began with were long ago converted to FM Pro 5.5 databases.
      I'm still using FM Pro 5.5 on a laptop with WinXP Pro, but in 2013, I purchased a PC with Windows 8. I haven't been able to install FM 3 on it, therefore can't install FM Pro 5.5. I am retired and rarely use Filemaker, but I have a few Filemaker databases I'd like to add to my Win 8 machine. I don't feel it's worth upgrading FM for the sake of using a couple of databases.
      Has anyone else run into this situation and/or have a (possible) solution? Is there perhaps any other software that can read FM 5.5 databases? Thanks in advance for your help.

      I am using a custom filemaker solution for medical office billing written with fp5 running on a mac with snow leopard. In addition, I have a patient management db (which I wrote) that is linked through pt. ID number to the billing program allowing transfer of some demographic information (name, DOB, etc).
      Other than being limited by hardware restrictions, the billing program serves our needs for now and upgrading to fp12 will take some time (and money).  In the meantime, I am upgrading my pt. management program to fp13 and would like to move new patient demographic information from the billing program ( fp5 running on snow leopard through Parallels) and the new pt management program ( fp13 running on OS X 10.9) on the same mac.   
      Ideally, demographic information would be entered once into fp5 and then a scipt would make the data available for fp13.
      Any ideas on how to make this work?

      Hi, can anyone tell me why my on-line database might have stopped allowing me to delete records?  All of my access privileges and passwords are correct.

      Hi, I still use filemaker 5.5 and am very happy with it and don't want to upgrade.  Does anyone still host filemaker 5.5?  Thanks!
