Multi User Enviroment

Nov 1, 2004

Hi everyone,
can anybody help me on this. I have two PCs connected and i am trying to execute an Access file from the client PC. This appears to be possible but the problem is that i cant save any new record and Active X or OLE seems to be the problem according to the message box appeared when i execute a form. The file works normally when executed from the server.
Any ideas?
It appears that the problem comes when Vba Code is executed for example i can save records from the tables but not from the forms where VBA code is attached

Taking Control Of Db That's Split In New Enviroment?

Jun 8, 2005

Can someone help with this problem?

I created a database for another department that I split and configured the FE to point to the BE via an IP address on my server at my office. It worked perfectly.

The department moved to another location outside of our building. I placed the database on the server in their new location. I configured the FE to point to the BE via a physical driver letter.

'z:sosvr1epl databaseepl_fe' AND 'z:sosvr1epl databaseepl_be'.

The problem is that everytime they access the FE it gives them an error message stating that the db cannot find the BE on the drive letter "s". I KNOW ... IT DOES NOT MAKE SENSE.

I tried to correct the problem by configuring the FE to point to the BE via an IP address on their server. It did not work because their administrator could not get the login and password to their server to work.

They also stated that whenever you make modifications in a different enviroment, my office, and bring it to another enviroment, their new building, you will need to take "ownership" of the db in the new environment. Ok ... I did that. I went into the security under the properties of the FE file, and viewed all of the staff that needed full control, and saw that everyone did have full control.

Please help me. I hope I explained this clearly. Even though it does not make sense. I am clueless.

an IP address on my server at my office. It worked perfectly.

Creating A Multi User Enviroment

Mar 4, 2008

Hi, i have made many access databases which run on standalone machines and perform tasks such as invoicing, stock checking and various other tasks for businesses.

My problem is, I have just been asked to allow multi user access to the system with updates performed almost instantaneously.

Heres the setup:
Computer One - linked to - Computer Two (via a computer to computer network using a simple cat5e crossover cable to allow access to the files on each system).

What I need is to have the database file so that both users can access it at the same time and any updates are virtually instantaneous.

At the moment with only one pc, if someone was to create an invoice the stock levels would all update automatically in the system so if a stock check is performed the correct stock level is always shown as it is only run on the one computer.

What i need is to be able to have the system open on both pcs at the same time and if for example User 1 was to create an invoice, and User 2 was to perform a stock check shortly after, the updated stock levels would be shown.

I trully have no idea as to how to go about this, and would like to keep it as simple as possible. Any help would be much appreciated.

Many Thanks
Jared James

MultiUser Environment Help

Oct 5, 2005

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.

Multiuser Issue

Sep 15, 2006

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

strSQL = "INSERT INTO USER_LOG (userID,dateEntered) VALUES" & _
"('" & Environ("Username") & "',#" & Now() & "#)"

'save userEntered so userExit can be updated to the right record
'this will be used to query the right record when the user exits
dateEntered = Now()

Set objCommand.ActiveConnection = CurrentProject.Connection
objCommand.CommandText = strSQL
objCommand.Execute

Set objCommand = Nothing

formload_errhandler:
MsgBox ("Application has encountered an expected error")
Resume Next

End Sub

Need Help...Multiuser Database Question

Apr 18, 2005

Hi-

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?

Thanks,

Derek

Slow To Access Multiuser DB On Server HELP

Dec 16, 2005

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

Access 2002 Multiuser Environment

Jan 3, 2006

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?

Record Locked In Multiuser Environment

Jun 3, 2006

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.

Any help is appreciated.

Prodigy.

Access DB - Multiuser Editing At Same Time Possible?

Oct 30, 2013

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.

Form Buttons Act Differently In Multiuser Envirnment

Aug 4, 2005

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.

What's wrong with this database?

Thanks for any help you can give me,

Double-Clicking,

Andrew

General :: Building Multiuser Apps With Access?

Aug 6, 2014

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.

Modules & VBA :: Multiuser Split DB - Code Causing Occasional 3049?

Dec 2, 2014

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.

Access 2000 & MSSQL 2000 Multiuser Problems

Aug 20, 2007

Hi everybody,

I have recently been doing a conversion for my boss for a access 2000 database (both front and backend) to a MSSQL backend.

I finished the conversion today (as quite a lot of the code / queries ran slow due to access running the queries locally rather than on the server). And tested it on my and my boss's machine with no problems so he gave the go ahead to update everybody to our new mssql 2000 backend with the modified frontend.

This is when the problems started; We had two different sets of forms for accessing one of our databases systems - the log system, one is the original dynaset based form, and the other is a newer set which uses snapshot views and preforms updates via queries. Nobody uses the old dyanset system apart from my boss and one of the administrative team as they have things on that window which they need to see. About 30 minutes into the release of the new database the system frooze up on my bosses computer and nobody could create a new log (the server was timing out). I assumed this had something to do with the old dynaset's creating locks on the table.

I offlined the database and kicked everybody out of the front end, turned it on again and tied again, this time banning everybody from the dynaset system. Within 10 minutes another computer frooze up, again with a timeout on the insert query. I discovered that after you had added a new log to the database it would timeout on all subquent additions (something it hadn't done during testing) . Further investigatiion showed it was the snapshot list window causing the error, so coded the add log window to close the list before preforming the insert query and then reopen it afterwards. This allowed my machine to make multible additions without flaw. So I released a new client to everybody. 15 minutes later it was timing out again, but this time there you could not even make one new record.

I checked for locks on the table though the server management table and couldn't find any for the Log table. I have restarted the SQL server box and with no avil. So I reverted our backend to the access mdb file and told people to use the old client.

I am at a complete lose to why this is happening, if anybody has had any expericences like this or knows the cause please tell me.

Some information on the database in question.

It was made as an access 2 database all intergrated into one file, then it was seperated into two files (frontend and backend). Upgraded to Access 97, then to 2000 before this final update to MSSQL 2000.

The log system has two main tables. The first is the log title / info table which links (one to many) to a log entry table. This problem only occurs on the main log table and does not appear to be reoccurring anywhere else within the database. The main log table has just under 18,000 rows in it.

Thank you in advance for any help,

Dom
