Here is a question that I hope someone would be able to help me understand so that I may be able to better program.
I work for a county agency. We have several offices located about 82 miles apart. From our technical services bureau, there may be as many as 16 switches, hubs, routers, etc., between each office. The main database is located in our main office. The remote office is able to access the main database through the county network. We are currently using fractional T1 lines. There are numerous tables within the database. There is one table which is the primary table from which all other tables are updated from. When accessing the database, from the remote office there is a delay of anywhere from 1 to 3 minutes. the main office has only a slight delay. The main table has approximately 250 fields and the .ddm file is approximately 4.4mb. The database has been optimized and each workstation has a copy of the shadow files. I am sure that there are a number of potentials for the delay including indeces being opened but the delay is very frustrating for the remote office. I understand that in using shadow files the request goes to the local drive thaen is redirectoed to the server, but for a script which may be only 30 lines, the delay is difficult to understand. Therefore, perhaps if I understood the way in which A5v4.5 opens and accesses files. Although the database is optimized it still appears that A5 may still be accessing some of the forms from the server instead of the local drive. There is something that is just not working right and I believe that it may be related to the way in which A5 is accessing forms.
Can anyone help with this and I can call to discuss this with anyone that truly has a good working knowledge of the way A5 works internally.
I could really use the help and perhaps this could be a problem that may help others with similar installations over long distances.
Thanks in advance.
