hi,
am trying to create an application for a company that has a small call-center (strength 20). the db is in the central server and each caller sits with frontend on their computer.
the central DB is shared on the network which these 20 PCs are accessing.
The frontend: 1 Form only which is based on a query that displays records.
Form Lock property: Edited Records
Query Property: Edited Records
As the telecaller starts calling the customer looking at the records, they are not able to edit certain records as the respective record is locked by MS-Access when am sure that no other telecaller has opened the particular record.
I am having some major problems so i thought i would ask you guys out there for some help because i am starting to bang my head against a brick wall.
I have a simple database, well i have 3 but the problem is only occuring on 1. each of these databases sit in a shared folder on the company network. I am trying to allow multiple users access this database but every time a second user tries to open the database they are unable to get access and receive this message
The table 'MSysAccessObjects' is already open exclusively by another user
However i have set the default open mode to be shared.
can anyone help as i really need this database to open in shared mode.
Has anyone deployed or is anyone using an access database in a shared drive environment over a network? If so, how is the databases performance and what kind of problems/headaches do you encounter in this environment? Thanks.
Hi! I have constructed a database in Aceess 2002 that four persons or more are going to work with. The users have there own computers in the same network. And they are going to work in the database at the same time the database is placed on a shared drive in the network. They must have the possibility to work in the same bookingformular. Is there something that I have to think about so that everything works allright? I mean in the multiuser environment. I had a lot of problems when rhe same people worked with an Access 97 database, But I hope that Access 2002 is better for multiusers. Is that correct?
I have attempted to create a test environment, by creating a blank database in SQL and restoring a backup of the live environment over the blank database (now called test db). I then took a copy of the Access MDB file,and renamed this to testMDB. I then created a new ODBC link to the test db and refreshed the links to the tables by the importing the tables.
Majority of the system works, but I have noticed that after doing this, the forms that access some tables appear to be 'locked', in that no additional data can be added. The page effectively looks greyed out. If data already exists on this tab, then it can be viewed, but cannot be edited. In the live environment, the form shows an additional line is so that more data can be entered if required and any existing data can be amended.
I have attached two screen shots showing the difference.
First of all hi everyone, im lookin for some advice
i have database setup with record level locking for multiple users (havent decided weather its should be optimstic or pesimistic yet)
however either way i set this there is no idication that the record is opened/locked by another user is there an easy way to say pop up a msgbox when a user enters a record to say this is in use/locked and show who by using the username?
I'm going live with my DB tomorrow morning. I wanted to to Edited Records for my lock type but ran into a problem, this weekend when I took it to our office and had it on multiple computers for the first time. (I've been designing at my house, in my spare time (right), so I couldn't test for the problem I have now.) When a user is on a record and I open the same record up on another computer it locks ok and shows in the Record Selector that it's locked but if I begin to tab through the form I have at least one code that pukes. In my LastName field, in the On Exit event, I have the following code: If Not (IsNull(Me.LastName)) Then Me.LastName = StrConv(Me.LastName, vbProperCase) End If As I try to Exit this field, only when the record is locked, the code pukes. Can some one lend a hand and give some advise on how to prevent this?
I have a database we use to enter new account numbers and several other atribbutes about the account and it is split into a FE/BE with the BE in a shared folder. I have the open database using record-level locking checked but it seems to me that the database is opening up with page-level locking. Multiple users will receive a message that the current record is locked and I am sure that they are all not updating the same record. Does anybody have any idea's of what I can do? If nothing else I am going to have to recreate my form as an unbound form and see how that goes.
I have done some serious searching and have discovered that many others have posted this question, but I couldn't find any satisfactory answers.
I have a FE/BE Access 2000 database in a multi-user environment. I have my default record locking set to "No Locks" (optimistic), but for unknown reasons, some records still lock. The records are viewed via a form, which is also set to "No Locks." We only have about 20 users, so it is rare that two people actually have the same record open at the same time. It seems to be that whole groups of records lock sometimes, despite the fact that I'm using optimistic record locking. Usually if you wait 15-20 minutes it is unlocked. If someone can explain this I would be overjoyed.
But, I can deal with the record locking. The problem is that users have no idea why they can't update a record and no matter how many times I tell them to wait 15 minutes they still come crying to me every time. So, I want to make a message box pop up when they try to update the record that states something like this: "The record is currently locked. Please try again in 15-20 minutes."
If someone could offer some code options and explain where it needs to go (form load, open, etc.) I would be eternally grateful.
Access 2002 . Can I condition a field to 'locked' on just one record of a continuous form subfile, based on the contents of a 2nd field in same record?
This is my first post but I am reading this for a while now and I learned a lot from this site. Now, I have a problem which I cannot solve and I hope that you can help me with some advise.
I designed database for production proces calculation and for warehouse management. I have BE and Fe which are on server and every user has the copy of FE for himself. FE is also on server. Maximum number of concurent users is 3. The problem is that sometimes I get wrong calculations.
For example, when someone click the button for finishing the production process, calculation of production cost goes wrong. But, that is not happening everytime. Let's say one of the 10 calculations goes wrong. I tested aplication localy on my computer and everything is working normaly. I also tested the database in network enviroment (in my house, BE on one and FE on second computer) and everything is also working good.
I have to mention that this factory is rather old and we are constantly experiencing power loss or voltage disruptions. And also I have to mention that network cables are not installed profesionaly. We bought several aditional UPS devices to secure the network from voltage disruptions and now I will test the database again. But, any additional help would be appriciated.
The strange thing is that I never get any kind of error message. Everything seems to work good, but when I look at the numbers I can see that some of the calculations are wrong.
And just one more thing. In my database I have some procedures which are based on several queries which are executed one after another.
In some places I have up to 7 queries which are executed one after another one (first query deletes the data from table, second one makes the initial calculation, thirdone updates the warehouse data, fourth is calculating the new price, etc.) Maybe this is the problem?
I have split my db and distributed the FE to client pcs while BE is on the network. To demonstrate it i have 2 users , userA who has read/write rights on the shared folder where BE is while userB only has read rights on the shared BE folder. When userA opens the FE he can get in(writing userinfo in the table on the OnLoad event) but when userB gets in the FE opens fine EXCEPT he gets the error that there was an error on the OnLoad event, which i am fine with because userB doesnt have right access to the db yet. But now if the FE is closed by both users and this time when userB logs(read rights only) in before userA(read/write rights) he gets in with no error on the onLoad event but now if userA logs in he is shown the same error on the onLoad event!!! i am totally lost as to what i have missed, can someome help? this is my code on the onLoad event in the FE:
Private Sub Form_Load() On Error GoTo formload_errhandler Me.InsideHeight = 5000 Me.InsideWidth = 10000 DoCmd.Maximize Me.picBox.Height = Me.InsideHeight 'authenticate the logged user Dim userName As String userName = Environ("Username")
'check to see if username is in the SECURITY table Dim objRS As ADODB.Recordset Set objRS = New ADODB.Recordset
With objRS .CursorLocation = adUseClient .CursorType = adOpenKeyset .Open "SELECT * FROM USER_SECURITY WHERE userID='" & userName & "'", CurrentProject.Connection .ActiveConnection = Nothing End With
If objRS.EOF Then MsgBox (userName & ", access denied") userAuthenticated = False DoCmd.Quit Else userAuthenticated = True End If
'at this point userAuthenticated is true 'log the user in USER_LOG table updating userID,dateEntered fields Dim objCommand As ADODB.Command Set objCommand = New ADODB.Command Dim strSQL As String
Dear All, My company have an application that is using Microsoft Access for the database. The Application created by VB.
Because of server hardware failure, I have to reinstall the server (OS Windows XP) dan also the Microsoft Access. Now my application cannot run in multiuser anymore after reinstall the server. My applcation still can run in client computer but cannot run simultaneously in several client computer, because if one client computer has access the database in server, the other client computer cannot access the database, raising error inform that the database already open by other user. what should I do to solve this problem ?
I have a form in a database that is just a look up form (you cannot add or delete records). How can I prevent this (see below or attachment) from happening?
************************************************** ******* 'FormName' has been changed since the last time you opened it, either by another user or because another instance of it was opened on your own machine.
Do you want to replace the changes that you or another user made?
*To save your most recent changes and discard the user's changes or your previous changes, click Yes. *To save this version of the object with another name, click No. ************************************************** *******
What's the best way to handle multiusers and forms? The database is split but sending the front end to all users is not an option. I've tried different settings thru the Record Lock...Locked fields...Allow Edits/Additions/Deletions...and we still get this message. I've tried adding 'DoCmd.RunCommand acCmdSave' to a timer. It doesn't help. I am at a total loss...does anyone have any ideas?
I not a big time DB person so please be gentle. I am a computer technician at a school district and need some help. We use a program called Aeries made by Eagle Software for out attendance and grading. It uses an interface that runs through Microsoft Access. There are two version of this software. One is the SQL version and the other just uses an Access DB on a server. We have the Access DB version running Access 2003. It was explained and accepted in the beginning that we didn’t really need the SQL version because of our district size which is some where around 1500 students. Our district consists of 6 school sites that are all connected with a fiber optic backbone running at 200mb with a minimum of 100mb to each desktop. We have a DB for each site running on 1 very beefy server in a central location. I’ve run my problem by the software maker and don’t feel like I’m getting much help. The problem I am having is slowness during login. When the first user of the day attempts to login the program is fast, about 10 seconds from “ENTER” to the main menu. As soon as that 1st user clicks one of the menu buttons anyone else who attempts to login to that database after that experiences at least 30 seconds from “ENTER” to the main menu. I’ve watched what files are accessed and when. I see that when the 1st user logs in, the systemxp.mdw file is accessed and a systemxp.ldb file is created. Then when the user clicks a button on the main menu, the sch05xxx.mdb is accessed and a sch05xxx.ldb file is created. The sch05xxx.mdb file is the main database file for any particular site. The “xxx” would be the site number. As soon as that file is accessed or that lock file is created the user will experience the long login times and sometimes as long as 4 minutes. I don’t believe this is a hardware problem. During the same time that users are slow I have made a copy of one of the databases onto the same HDD on the same server and as long as I’m the 1st person to open it, it will fly. The 2nd person is slow just like the rest. I also don’t think it’s a permission issue, at least not in the domain. I’ve run all these test logged in as myself and have Domain Admin rights to everything. I believe this is a “split database” with the tables on the server and the forms, and queries on the users computer. I read an article here, http://www.microsoft.com/office/previous/xp/columns/column05.asp called “Why is Access 2000 slow for more than one user?” Has anyone else had this problem or have a solution? If I’ve missed something and you need more info please let me know.Thank you for your time and I appreciate any responsesJohn
We are trying to cut down the # of spreadsheets we have and took a purchase tracking spreadsheet and turned it into access db (2010).
We have 3 sites, and users across network would be 1-2 at max might be in db at same time either recording a purchase, or updating a record on received items.
Can this cause corruption? Is there a way to set users up so it won't?
I know in older versions of Access there were shares that could be set up.
We recently put together a database for a call center. The file is located on a public drive, and all users seem to be able to access the file (at the same time) and input new information.
On one particular form, I've found an interesting problem: I've placed a button at the bottom of the form, which will go to a new record when clicked. The command to go to a new record is clearly in the OnClick event, however users in the call center have to click twice in order to execute the code. I don't have to.
We're using the same form, in the same file, opened with the same version of Access.
I've always setup Front Ends and Back Ends so that a copy of the Front End is distributed to each Desktop.
I've now joined a new company (been here 6 months now) and the way things are done here is that one copy of the FE sits on a share and users open it from that location. This file contains no local tables and all data is connected to either Access or Oracle databases using ADO. The FE has built been utilizing User Defined Types to read all data in to memory.
I have a multiuser split db with this code on a listbox:
Code: Private Sub lstsearch_DblClick(Cancel As Integer)
' The following is the variable definition for the error handler On Error GoTo lstsearch_DblClick_Error Dim ErrorForm As String Dim ErrorControl As String
[Code] ....
The error function sends me an e-mail listing the error, user, form and sub. Ocasionally some users get error 3049 when running this sub. It is generally one user out of about 10 or so and the db keeps working fine for everyone else. I have reviewed the back end several times and I cannot find any obvious corruption signs. I have compacted and repaired it several times with very small changes is size.
Hi guys, i read about this before but it did not work.
i am trying to hide the access environment but i couldnt. i read in this forum that if i have a bmp with then same name than the db, the picture would replace the access environment. I have done this but the only thing that i achieved was to see the picter before access env. comes and then it desapears and the access env. shows up.
I was wondering if anyone would be able to help me here.
I have a database created in Access .MDB. It operates allright on my machine. However, since this database is done for my client, i have a problem i need to ask for help.
My client doesn't have microsoft office software installed on their machine. So when i passed the database onto them, they somehow can only run it in the run-time environment. Don't ask, I'm not sure about this at all. Anyway, They came back to me saying that they have got a run-time error message in the middle of running the database.
On my end, it's hard for me to debug since it works fine here. I was wondering if anyone would be able to tell me how i could have this database run in the run-time environment as my clients do. This way, i could debug the problem.
Is it possible for me to run my access database in run-time environment? how do i do that?
I need to allow my MDB to have 15 users accessing at the same time. They will be updating different parts of the same table using different forms. The system will also do an automatic update from another system in 15 mins interval.
Is it possible? If so, how do I configure my access database?
