    Limit to file size

    nadineschaefer _

      I did a quick search for my problem and did not find anything.


      I have Monarch Pro 7 on my local computer and access to Monarch Pro 8 via Citrix server.


      I have a text file that is 18GB. That has data date form 1989 to 2002.


      At the moment I have a database that is opening this file and running it through Monarch with model that has run time parameter on it. This works but takes for every (about a day). One of the reasons why is the file is on an external hard drive.


      What I want to do (and tried to do) is extract each year’s data and put into a MS Access Database.


      I keep running into the problem I am not extracting all the data from this large file by for each year. When I did extracting the data for one year I did it as the following:


      There is a text filed that has the data mmddyyyy.

      Set up a filter with *yyyy

      Then scrolled to the very bottom of the data (or what I thought was the end)

      Export to an access database.


      So my questions are: Is there a limit to the file size monarch can work with? Is there any limit with exporting from monarch to access (other then access 2GB size limit)?



      Any insight would help

          The process will create temporary work files in the folder specified for such things, the largest of which  is limited to just a touch over 1Gb which does in fact realte to the Access 2 Gb constraint.


          It's not a limit for the number of records as such but rather one for the total data capacity in the process. A lot of fields, and especially a lot of calculated fields, can eat into the space available.


          It may not be easy to come up with a usable alternative view.

              Dear Nadine,


              I've come up against the same problem at a recent customer. One option is to run a script against the file to break it into smaller chunks. It might also be worth looking at using Datawatch|ES rather than desktop Monarch.  Rather than create an Access database of each year, you could preserve the report archive and be able to query across it.


              Best wishes,

                  Don't know whether this will help, but have you tried openining the text file as a database in Monarch and applying Source Filtering as it is opened. I have used this on somewhat smaller text files, but do not have anything like the size you are working with.

                  If it works you should get a Table of the filtered data you can then export to Access.


                  Best of Luck
