Upsizing
Mar 5, 2007
I have a MS Access 2003 database that is getting corrupted frequently. I am following all the rules to avoid this problem but it keeps boring me with "Access can´t recognize this database format" and I lose all my data.
I´ve sent the db to experts to try to recover it and they told me that it was impossible. So, I´m planning to change my Backend (BE) and keep my Access Frontend (FE), because I like Access very much.
My question: what is the best solution for BE?
SQL Server? Firebird? another one?
I hope by changing the BE I won´t have problems anymore...
Thanks in advance

Would anyone be willing to have a discussion about upsizing a large split database to SQL? I've managed the split using the wizard and it went very well. The problem is the performance, the form is really slow on opening and as it scrolls through records.
All my queries are saved. I would imagine it's the way I've built the form and base queries that's causing the problem and wondered if anyone would be willing to have a look at it for me and see if they can make any suggestions.
I'm struggling blind with this one.
Thanks.

After Loading MSDE and running the upsize wizard should I be able to create an ODBC link to the data using a SQL driver?

Ok......
It's much as I thought it would be. MS Access is limited for a mid size database application. I have developed this mid size database for the medical clinic I work for. I didn't want to do it, but they saw some of my personal projects I created and pretty much told me to come up with something.
Well, the good news is, the database itself works exactly as designed, meaning it does its job very well. The bad news, and I knew it would happen, is instability. When I first started creating this program, I had no idea how many people would be using it at once. That, and after reading through these forums for the last few months, I realized that Access wasn't the puppy to be creating this database in. As it stands, about 130 - 150 systems access the database (about 3 times more than I originally forcasted.)
I'm sure those of you who have done something similar knows the next thing I'm about to say...... yep..... mysterious run-time errors - locked database from time to time - owc (office web component) errors...... etc. etc. These errors pretty much happen during peak hours.
I am pretty positive it's because access wasn't designed to handle such a load..... which led me to a researching a resolution. The answer that may be my savior is the upsizing wizard included with ms access. We do have MS SQL server running on a server...... I was just curious if anybody's ever used the upsizing wizard; either that, or has anyone ported an access project to sql. (This is a big program, and would hate to have to reprogram)

Greetings:
I have been using front-end back-end database, which consists of three .mde files connected to an .mdb backend on a Windows Server 2003 Windows XP Professional network. The database is a flat-file. Because of problems associated with record corruption, related to multiple users and memo fields, I am looking to upsize my backend to MySQL or SQL Server both of which I know little about. Additionally I am hoping that upsizing will help alleviate the slowing down I am currently experiencing as the back end grows.
My question is am I looking in the right direction will either of these correct my problems and if so which of the two should I use.

HI.
Your help is very appreciated.
*I upsized ACCESS 2002 (tables only) to use SQL SERVER 7.0 as backend.
(linked tables).
* Almost all the ACCESS forms are bound type forms.
Now, I have two problems:
1. Other applications (not ACCESS ones) that use different dbs on the same SQL SERVER , are slowed down / halted.
2. My SQL SERVER license is limited to 8 "user counts". When there are 8 instances of the ACCESS app, any additional connection request is refused (from any app).
(I can't afford buying more "user counts").
I suspect that beacuse the forms are bound, it hold connection open as long as the form is used.
Also, each ACCESS app instance, opens its own connection.
The solution that I see, is to use unbound forms(disconnected), and opening the connection in code using connection pooling.
Would you recommend on this solution?
do you have any suggestions?
Thanks a lot
Roy

Hi,
I have developed a couple of database applications. This started as a small thing but now is growing to the point where I've got to make some decisions and would appreciate some guidance.
Presently:
Front end: 4 Different GUI's as local front ends.
Back end: Intranet network share on Win2k desktop (limited by O/S to 10 connections at one time)
Going forward, about 30 users will have access to the front ends and will all need concurrent access to the back end data. At some point, I would like to generate web pages from the data in the back end database and have the back end machine also be the web server for this.
So, what are my "best" options for the back end?
I was thinking of getting Win 2k3 Server running SQL server to drive the database.
The ability to integrate security with existing infrastructure would definitely be a plus, which I believe Win 2k3 can do.
I don't know very much about Win 2k3 or SQL server, but am willing to invest in learning the ins and outs as long as I can get it up and running with the same functionality I have now (with relative ease) and scale it as my capabilities with the OS and SQL server increase.
To be honest though, I am a little scared about how much I'll have to change my existing applications in order to make it work.
Your suggestions, comments, experiences most welcome and valued.
Thanks,
Al

I have upsized from Access 2003 to SQL Server 2008 R2 using upsizing wizard. Everything works fine. But I don't see relationship in SQL SErver 2008 R2 if I go to database. But I set relationship in Access 2003 before upsizing it.
Amso I don't see relationship (diagram) in Access 2003 , which I was able to see before.
So do I need to again recreate the relationship amongst the table in Access 2003 Or SQL SErver 2008 R2 ? I thought, if you link tables, everything should be taken care but i don't see relationship structure any more.
