Access 2007 Performance Help
Oct 27, 2007
Hello,
I am attempting to convert some Access XP MDB files to Access 2007. I am experience some horrendous performance problems. We are a bit unusual in that we use Access as a RAD tool and almost all of our data resides in Oracle tables linked to by our Access front ends.
The issue I am experiencing concerns opening tables in the UI. If I open a table by double clicking it, a datasheet view is displayed (rather quickly) as usual, filling the page with information. The UI is responsive while Access populates its recordset in the background. (e.g. the the record count on the record navagtion bar is not displayed). As soon as I click in a column defined as a date, the UI hangs, network trafic and CPU usage rise dramatically and the Access Window displays "not responding". It appears that Access is attempting to retrieve all the rows in the table. After 3 minutes or so, the UI becomes responsive, CPU and Network traffic return to normal and the record count is now displayed (roughly 900K records).
This is "bad" (and also not what Office XP did). Please can anyone help?
Thanks

Hi everyone
I'm starting a year-long university project which will be written in c#. The client app will be run on a LAN, with 35-40 users accessing the database concurrently, connecting to a database held on the server.
Could anyone tell me if Access can withstand 35-40 users at the same time? I found out that the maximum amount of users is 255, but what kind of performance impact(if any) will there be with 35-40?
I've searched all over the Internet for this, but I can only find references to using access behind a website, which isnt quite what I need. Any help would be great.
Thanks.

Hello,
Have a few questions after I ran the Access performance analyzer. Now these ideas are they good or just some generic recommendations. Dont know if I should take care of all these or not?
Anyone know if I should do all these things and about how I should do it?

On trying to import an Excel 2007 file into Access 2007 I get the following:
1) Choose "External Data," Import, Exce
2) Select small file in MS Excel 2007 format.
3) Click on Import the source data into a new table ...
4) Choose OK
Immediately get "Microsoft Office Access has stopped working. Windows is checking for a solution to the problem..." This message never resolves, so I have to click 'Cancel'.
Then I get "Microsoft Office Access is trying to recover your information..." I have to click "Cancel" here as well and then kill MS Access in Task Manager.
Event Viewer gives following message, which is of no help:
"ID: 2, Application Name: Microsoft Office Access, Application Version: 12.0.6211.1000, Microsoft Office Version: 12.0.6215.1000. This session lasted 710 seconds with 120 seconds of active time. This session ended with a crash."
Trying to import a small Excel 2003 file leads the same result. The same happens with a CSV file.
I have uninstalled and reinstalled Office 2007 as well. I am using Vista Ultimate.
I have turned off DEP.
How can I get MS Access 2007 to import Excel?
Thanks
Ken

My situation is as follow
I have an Access datebase, where main tables are built and saved.
Also, I have 2 Access modules, which access informations in main tables in an Access datebase (I used Linking to table) and process information in query.
Questions: Linking to tables in another datebases will make perfomance of the module worse ? If the answer is Yes, then in which scale ?

Hi all,
I am programming a database that contains approximately 3700 records stored in a relational table structure.
When I split the database and moved the tables to the server side, my performance worsened drastically: a query that runs in under 5 seconds when the tables are on the client side takes over 45 seconds in the split database (with tables on the server side).
I've tried a variety of solutions (including changing the subdatasheet name property to [None] in the tables, creating an MDE file from the MDB file), but they haven't helped much.
Any suggestions about how to speed performance are greatly appreciated! Thanks so much!

I installed Office Enterprise 2007. Then I installed DEveloper Exrtensions, then Access Runtime 2007. All appear to have installed OK - they appear in Program and Features.
Instructions on runtime packaging tell me that a Developer option should appear in the resulting drop-down when I click the Office button (top-left round thing) when I have a d/b open in Access. It's not there! I have un-installed and re-installed the extensions and the runtime - still nothing!
Help!
I do have Runtime 2002 (XP) on the same PC, is that relevant?

We are encountering severe performance problems when running our access database on our Network.
Symptom:
Huge drop off in performance when 2nd and subsequent users refresh links to chosen back end database. If the database is opened by another users front end database.
Takes up to 10 minutes to refresh the links to 120 tables in Back-end MDB database.
The system is designed as a split front and backend Access database. The back-end Data MDB database is located on a Windows 2000 server.
The first time a user logs on they are required to locate and Re- Link the tables from the back-end database which holds data for the current year. If they wish to work on another year they re-link the tables from the relevant back end database.
When running locally the Front end takes between 5 and 10 seconds to refresh ALL the links to around 130 tables.
When the back end is on a network drive the process takes about twice as long. But is still quick.
If another user has the file open via their own (locally held) front end, then the refresh link process takes between 5 and 10 seconds PER TABLE !!
This means that that it takes up to 10 minutes to complete the re-link.
Same behaviour if using Linked table Manager or refresh links using code
As soon as second user logs out of database the refresh link process speeds up.
The behaviour has been observed on a variety of servers and customer networks.
General data access is also much slower after 2nd user - but just about bearable. Data files are small – few records – occupy 7mb on disk.
Development Platforms – Windows XP / 200 clients, Windows 2000 Server hosts the back end database.
Front end is Access XP (MDB or MDE File) with al the latest service packs and security updates installed.
We have experienced this problem with a number of different systems running in various environments. But this wasn’t a problem with the old Access 1 database
HELP! Access should be able to support 10 – 20 users - we can barely run 2!

Hi folks!
I've been experiencing a very frustrating problem recently.
One of my databases crahes randomly, and I'd like to know if some of you have tips to helps me.
The database is splited in front-end and back-end, both on the server. I know keeping the front-end on the client PC will improve performance, but due to a high number of users (about 60 to 80) and the need of doing frequent updates, installing the front-end on each machines is not an option for now.
Users are not all directly connected to the server. Those who are directly connecte4d to the server (in building A) have no problem. Those who don't (building B) have extensive lags on opening (about 30 seconds), and on about anything that calls an heavy query, most often leeding to a crash. Access display the message telling that the datbase needs to be repaired and restart.
I tryed several thing to improve my queries, like eleminating most of GROUP BY and UNIQUE clauses and avoiding the use of functions.
I have a lot of conditional formatting in the forms, but I don't think this is the problem, since it is executed on the local machine (as far as I know).
My theory is that the lags cause some call to the DB to timeout. I just dont know how to fix that. Is there an option to higher the timeout delay?
My other theory is that the problem is caused by dropped packets during the connection to the DB. I tryed downloading large files (100Mb to 250Mb) from the server several times and never had a problem. Although the connection is quite slow, the ping is very small, like below 10ms to 20ms. Is there better ways to test a network connection, if possible without installing software (limited rights on the machine)?
Would using Replicas be a solution? What are the pros and cons of it? I never used them and know very little about it. My idea would be of putting a back-end on both servers, but I guess the data would not be as live.
BTW, I am using Access 2002 (2000 file format) on an XP SP2 PC.
Thanks to all of you patient enough to read all of this! I Hope some of you have some awnsers, tips or tricks!

I have an Access 2010 database .. and will be adding about 25,000 records a day to it. So it will get pretty big fast .. so 9 million a year. Is this too big for Access ?? Or is it more a issue of file size .. I know that Access 2010 can go up to 2 GB. I am interested in how I can maximize my performance and not have the database.The data is as follows .. One table. The other tables will be small, just this one will increase in size really.
Id .. Autonumber (primary key)
When .. datetime
Radio .. integer (indexed .. w duplicates)
Group .. integer (indexed .. w duplicates)
Type .. text 4
TransType .. text 2
I am considering a purge of old records if needed .. like only keeping the most previous 5 million records or some reasonable number. Like .. then I would think I should try to number my records backwards (using long int rather than autonumber and number records backwards on import) .. ie record 1 would be the most recent one and only keep the last X number of them for performance reasons.

Attached is a screenshot of the relationships in a database I built a couple of years ago. It's worked absolutely fine in Access 2003 and currently has over 18,000 customers with associated information in it.
However, when I open the database in Access 2007 the performance is awful. All the forms are very slow to respond when tabbing between form elements. I've experimented by reducing the number of form elements calling on related data on a given page and whilst this improves performance it reduces usability - something I don't want to compromise on especially since Access 2007 should be able to cope with this.
My next question is therefore whether I've got the most efficient underlying table design and I can't see any other way of doing it than my current method so I'd be grateful for any feedback or advice anyone has.

Hi All,
Background Info: I developed our main department's Access 2003 split database which is on a server for 15+ Users. I've now been given Access 2007 for development -- Users still have 2003. There are also 2 other smaller databases that are not split (.mdb).
Problem: In the split database, I've saved the Application .mdb as 2003, relinked and made a new .mde. But the Users still cannot open the database. (I did this in a copy until I figure out the nuances with 2007.) The 2 other unsplit databases can be saved as 2003 version and Users can open OK.
I'm grateful for any suggestions on working with Access 2007. I've been trying to tackle the ribbon which is a whole other question.

I have created a database in Access 2007 that now works well, and one that I'm quite proud off. However, I can easily convert it to an Access 2000 format as can anyone else here, but when I load it up there is a major problem.
I have used the tab control in my main form and that has three tabs on it. However, it's positioned correctly in Access 2007 it's not positioned correctly in Access 2000 as I have to move the tab control down a bit, but that would seem fine. So I lowered the tab control form and changed my form layout slightly, but even then the tab control over all over the Access 2000 form whenever I interact with the tabs - most bizzare.
Any help? Thanks.

I recently heard that Access 2007 ( part of MS Office 2007) can be purchased as a stand alone program. This sort of confirms that : look at pricing breakdown on : http://techrepublic.com.com/5254-6257-0.html?forumID=99&threadID=174062&messageID=1961442&id=3053951
Anyone done this already ?

Hi,
I have downloaded Access 2007 trial, but I don't know how to use some of its features. When I try to open any of my databases saved as A2000, it displays a security message. "Security Warning: Certain content in the database has been disabled"
Is there any way to disable this message?
Any help will be very much appreciated.

Will I be able to convert my database directly, or is there some way I can convert it indirectly. ie by converting it to an earlier version first?

Hello everybody,
I would like to hear your oppinion about new MS Access Jet db engine
I've been working with MS Access still 10 years, since version 2.0. I used to use MS Accesss for companies size of 10 pc users, and for any bigger company, I used MS Access as front end and MS SQL Server as back-end.
I bought recently MS Office 2007, with MS Access 2007. Before that, I read in one computer journal, that new, Access db Engine is completely made from scratch. And that this new engine is so good, that there are no needs to work with , for example MS SQL 2005 express.
Also, I read, that during development phase of MS OFfice 2007, Microsoft development teams SQL Server and MS Access in Redmond, USA, fought among themselves, about is there need for Jet db engine, or not.
Engineers working in MS SQL development team, made a pressure on Microsoft board, to remove Jet engine from Access, as you can take MS SQL express for free, but on the other hand, MS Access dev. team, replied that new Jet is robust at least as MS SQL express 2005.
So, my question is: what do you think about it, is new Jet db engine, really so good and robust in MS ACcess 2007 ?
with regards,
Z
