I have a relatively small database of approx 28 MB - for 5 users max on Access 2007 -since the upgrade from '97 I have noticed a significant degradation in performance over the network - not so much on my machine which is the server/host machine but on the clients. All are Pentium/Celeron processors and recently I have beefed up the working memory to approx. 750MB/ 1GB on all these machines.
Even so, on occasion, I might type something in a field on a form - Access seems to 'fall asleep' for 10 seconds or so and then wake up again. Indeed, the window caption states (Not responding) .... This is not happening all the time but enough that when it does happen it is particulalry frustrating. Has anyone else had a similar experience?
I am thinking of splitting the database into a front / back end to resolve this issue but perhaps it is not a network traffic problem / the database isnt really that big considering others that I have read about on the forum that run into 100 of MBs! - can anyone suggest this a sensible idea / or could I regret at a later date?
I work with an Access 2007 database that I split into a front end and back end. The back end holds all of the tables and the front end holds the queries, forms and reports. It is also a multi-user database, in that we have 14 people having access to the same back end. Each of the 14 people have their own front end. I have one main table in the back end listing clients and their individual ID numbers. That table has a One to Many relationship with several other tables, such as Case Notes and Authorizations, to name a couple.
Here's one of my problems: Sometimes data that is entered by a user will disappear.
Example 1: User creates a new record in the Authorizations form. Sometimes it is created by duplicating an existing record, sometimes it is completely new. User then prints a report from that new record, which looks like it has been saved. A couple minutes later, or a couple hours later, or maybe even the next day, user goes back into the database and cannot find the record that was previously created. At that time I look in the back end and cannot find the record either.
Example 2: User creates a new record in the Case Notes form on Day 1. These are always completely new records. User returns to the database on Day 2 and the new record sometimes does not show up in the form or in the back end table.
I cannot MAKE these things happen and they are sporadic, which makes it hard to diagnose, but why this was happening or if there was a way to retrieve the lost data.
I have designed a database which I intend to split for multi-users to access from one front end icon on a shared folder at work. I have designed a form bound to cmr record table and on it a subform to another table where cmrs activities will be saved. The form has buttons to and blank controls.
User can create a new activity entry by typing into the blank controls and pressing the save button which saves to the activity table. the edit button extracts a selected records details (selected on the subform) from the activity table and populates the blank field for a user to edit and then hit save to save changes. The delete button deletes a selected record from the activity table. I intend to have multi-users either accessing, viewing and a possibly editing the same customer at the same time. The simultaneous viewing is essential but the simultaneous editing, though not desired is inevitably going to occur.
What I would like to know is:
1. Can you lock an individual record in a table or does the whole table have to be locked. E.g If Colleague 1 is editing Cmr A's record in Table1 can he lock it so Colleague 2 can view and edit Cmr B's record in Table1
2.Can Colleague 1 access/read Cmr A's record in Table1 to retrieve details toe the form controls if Colleague 2 is viewing or editing Cmr A's record in Table1
3. If record lock is possible, how can I initiate it in my example code below.Edit activity record Code
Code: Private Sub Edit_A_Click() 'Get Data to text box control With Me.R_P_Data_P_Subfrm.Form Me.txtrID = !rID Me.txtrID.Tag = !rID Me.txtrefNo = !refNo Me.cmbrpc = !rPC
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.
:confused: I have read a quite a few threads on spiting the database. My database is 50 Meg and running very slow. I have compacted and repair, still the same. This just happen all of sudden. Could that be possible?. What should I look out before I try to spit it?. It’s given that I will make a backup. I am running Access 2003. I have over 150 users.
I am almost at the finishing line with a great deal of help from here. I have now normalised the tables, built complicated queries, forms, reports, all from scratch as I knew absolutely nothing before I started with Access three months ago. I have compacted and repaired the database using the wizard, and also complied the code and analyzed all tables, forms, queries, and reports and relationships. The final step is to make it an MDE file so that it can go on the local network at work (not on the internet). My questions are these;
Do I need to split the database into front and back ends?
If I save a copy of the original MDB file and then make it a MDE file would that not suffice in making it run more efficiently?
Can a split MDB database be made into an MDE database?
I have a database that resides on a file server share. I have split the database to create a backend. I then posted a shortcut of the front end to the desktops of two users who have access to the share. I then tried to access the front end from the two machines simultaneously. It opened on the first PC but not the second? When I viewed the server share it had a 'padlock' icon?
Where am I going wrong? This is the first time I have attempted this scenario!! Thanks in advance, Phil
Should splitting only be done when all tables,queries,forms,reports, etc. are done. Or can it be done anytime. I am almost to that stage but didnt want to jump the gun and run into problems later on.
I was having a discussion with Rickster57 concerning my newly developed database, and he recommended that I split it so that it has a front end and a back end. Rick listed a number of very good reasons for doing this (so I will definitely do it). But I wanted to pose the question so I could get some of the reasons the more seasoned Access programmers have for creating a front and back end to their programs.
I recently split my database and also used Bob Larson's Autoupdating tool. Everything appeared to be working fine until a few users were unable to access the db. I later found out that because they are at a different site, they don't map to the server that houses the database BE. However, even if they manually map to the correct server, they are unable to bring up the db Form. They get an error stating the BE "...is not a valid path". My questions are:
1) If I were to copy all the files (the Master FE, BE, and MDE) to a public folder that ALL users have access to, will everyone be able to bring up the database Form?
2) How would this affect what was already set up when I ran Bob Larson's utility (or even the splitting and MDE creation)?
3) Is there a way to "Undo" what was previously "Done" to this database (ie: Splitting, Larson Utility, MDE creation) in order to correct the issue, or do I need to start from scratch and split the database while it's on a Public drive.
I hope this makes sense. Thanks in advance for your help.
I just want to know that " How to split the Access database in Front End and Back End application"? I am creating a database that i want to store on server and simultaneously want to give access to 20 terminals (cleints) to access the database.
Secondly, I have to provide a field in a form "Document number". However as per the requirement user can enter "PIR No", "Serial No" or at times both as document number. Both the things "PIR No" and "Serial No" have different format types like "PIR No 001" and "Srl No001".
On basis of document number later i have to give the option to search the particular document. Please guide me how to provide the option to enter the field values.

I am combining 12 Databases. I have split all 12 between the server and the desktop. My question is “Should I combing all of the data table on the server into one database or should I leave all of the individual application data tables in separate Databases on the server”. Additionally, is there a limit to the number of tables an Access DB can handle? My inclination is to keep the functionality separated but the problem I have is that some of the functionality within the applications overlap. Recommendations!
The moment of truth finally came and I split my database FE/BE for testing only the truth was a bit sour.
Background: I have several forms in my database that have a common series of buttons at the top which open their corresponding form. Before the split, everything was fine - you can click on the button and the desired form would open. After the split, I'm getting the error message:
"Microsoft Office Access couldn't find the toolbar 'EVM Database Menu'."
This is referencing a toolbar that I used during development to help jump to forms.
I tried removing the toolbar from each form (Tools > Customize > Toolbars > unchecked the custom toolbar), and re-split the database FE/BE ends, but to no avail..
So, I checked the event codes to be sure I didn't program something wrong. There are 9 buttons total to open forms, 7 of them give this problem, the remaining 2 do not. The code for the problematic and non-problematic ones are identical!
Example - Non-Working (error message re: Custom Toolbar): ----------------------------------------------------------- Private Sub cmdActuals_Click() On Error GoTo Err_cmdActuals_Click
Dim stDocName As String Dim stLinkCriteria As String
Example - Working (no error message): ----------------------------------------------------------- Private Sub cmdPerfProj_Click() On Error GoTo Err_cmdPerfProj_Click
Dim stDocName As String Dim stLinkCriteria As String
Questions: So..this has nothing to do with code, it must be a problem in the linking somehow, right? A bug possibly? What else could be causing this? More importantly, is there a solution to my predicament that anyone could help out with? Searches so far have returned no help either from forums (including here), MS site (no Q-articles), and VBA Help. I'll continue searching though.
Hi, as an attempt to improve database performance, I have split a MS Access 2003 database. I have successfully split the database and saved the backend onto the server. My question is, where is the front end. or do I have to create it?
I have a database that I've created for someone else to use. It's split into a front and back end. The user will be placing the front end on her desktop PC and the back end on a network server.
She also will be taking the database home to use from time to time. My problem is that when the database is split, upon opening, it looks for the back end on the network drive, which is unavailable when she's away from the office.
Is there a way to tell the Access to look in a directory relative to the one it's in?
I have a call tracking database with 5 active users. Ocasionally the database will freeze, usually for several people at once. It will say: "Can not update record; Currently Locked"
The only way to fix it is to close and re-open. I split the database, compiled it and then created an MDE file to distribute. They are using copies of the front-end, not links. The database locking more and more every day. But we are using it more. After parusing the forum I'm starting to suspect that this is a problem of "Primary Key duplication" If everyone trys to create a record at the same time, would the database lock because we all created the same record at the same time?
If so, how do I get around this? Use something other than Autonumber for the primary key? Or is this an entirely different problem?
Hi all, I have noticed that ever since i split my database there is a considerable slow down of load time! When multiple users are on, it is also incredibly slow. is there a practice to follow to speed up the database? each user has their own front end, so im not sure if there is something else that can be done to speed it up
I am new to split database format... If I put the backend on say windows server 2000 or 2003 in a folder, is there anything else I need to do? Any setting on the server?? Or do I need a specific type of server os ie sql server etc?
Hi All, I have a split database. One of the processes I've created, copies a new table from a previously created blank table. It then imports data from an Excel spreadsheet into the newly created table. My problem is that now when the import occurs, the data is getting imported into both the new table as well as the blank table. For some reason, this only occcurs after the database is split. I've tested on a backup copy that is not split and everything works fine.
I have this problem. I have successfully split a database into a front end and a back end database. Well it has been going great for about 2 weeks now but the thing is I would like to take the database home over the weekend to work on it. I don't know how to properly put a split database on a CD. Every time I tried copying it, I get an error when I get home and try to use the CD. Can someone point me on the right path.
Also one more thing, is it possible to have a password on the backend database to protect the information from snoops?
So I split my database into a front and back end, now i wanted to add a table to the database. I created the table in the backend but I am not sure how to make it appear in the front end. I am using access 2010. I tried the link table manager but the table I created doesn't appear there.
I have done the mistake of not keeping a backup, what I did is split my database file access and then created my mde file, I need to change some data on my tables, but I get the msg that I cant edit a linked table, is there a way that I could put things back the way it was, also this path that was created is it possible to change for future purposes (I might have to move the dir into a different path)
Im trying to add 2 new tables to a split and linked database... but no matter which side i add the table to (BE or FE), it wont show up in the linked table manager.. so my question is 1.) is there some trick to getting it to show up in the link manager? or 2.) is there some way to re-merge the database, add the new tables.. and then split it again?
Since splitting my database into a front & back end - when I attempt to run the front end part from a client PC logging in as one of the users/groups defined I get : 'Disk or Network Error' and the DB fails to open.
If I log in using the same username/group bypassing the config/startup options - I do see the Access Design view main window - but then if I attempt to open (not all) most of the forms in Form View - I again get the same 'Disk or Network Error' message each time.
Yet, if I log in as the administrator from the same workstation - no message appears?
Everything we peachy-keen with my database until I split it and I get the following error:
"The expression On Menu you entered as the event property setting produced the following error: User-defined type not defined."
Please help as I'm not sure how to proceed. Here are some facts:
1. I'm a noobie with Access. I've been clever and resourceful enough to figure out most answers to my questions, but searching for this one have turned up bare.
2. There was a single custom Toolbox present before splitting the database. On the Import, though, I used the option to import toolboxes/menuboxes (checkmark at the bottom on the Import page).
3. I've checked for missing/broken References, there are none being reported.
4. The 'On Menu' event exists nowhere to my knowledge! Where can I find it and hopefully troubleshoot the problem?
Your imput welcome, I'm defeated for now, but am continuing the search for an answer. Please help ;)
