Shared Database Problems
Dec 19, 2006
hello everyone... with the help i have gotten from this site I embarked upon producing a online booking databse for my workplace ...
since the work enjoys having an intranet i simply placed the database in a shared folder and things have worked great for nearly a year ...
Ive tinkered and modified and everyone is happy till today ....
while an administrator was deleting a booking things went haywire ....
a message came up about couldnt delete because someone else was deleting ...things froze and a message about path problems came on the screen..
the only thing we could do was delete the database and replace it with the backup copy we have.... everything worked great for an hour or so and then things went wonky again with same error messages...
also I noticed that the database grew in size from 1.6md to 2.5 mb ....
again I replaced it with the backup copy and did a repair and compress ..and it seems to be ok ..
but im dreading tommorrw since i anticpate it happening again ..any suggestions appreciated... ps ..the databse is a booking form for booking ict suites in a school and I am the schools technician
cheers

I have a problem that seems to be happening on several users' databases and is causing a big problem. None of the databases is a shared database...they are all single-user databases on stand-alone computers. I have tried looking for help within previous posts, but all seem to be related to shared databases.
I am getting an error message: "The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time." The database cannot be opened, imported, repaired...nothing seems to work.
Again...these are NOT shared databases. I appreciate any help I can get. I created the database for all of the secretaries in our school district to keep up with absence data. It involves many tables, queries, forms and reports, and has generally worked well. However I am now seeing several that are getting similar errors as mentioned.
Thanks!

Hello,
Im having some problems sharing a database. I need multiple users to be able to open the database at the same time. I have check TOOLS - OPTIONS - ADVANCED and my option is set to shared, but for some reason it will still only allow 1 user to open it at a time.
Does anyone know why this could be?
Thanks

Have created a database that will be placed on a shared drive, giving access to others to add, delete, modify records. That aspect of it is fine -- but how to I prevent someone from deleting a field?

I have a problem related to shared access to a MDB file:
- I designed an Acccess Database and need shared access to everybody for read forms , and also I need (just for me) to do some "real time" modifications in the tables. I work in a huge company and cannot make changes in the Access of each user, just can work on my laptop. The file is placed in a shared folder.
- I can assign policies to the folders (for example I made a read only folder, with admin rights for me, but when somebody opened the mdb, I got an 'open only advice, and couldn't update any table; It's curious because the users coudn't generate the LDB file but still the access denied me the chance to modify any table when the file is opened by anybody).
- I tried playing with tools-security, but I cannot change every user settings, it didn't helped me.
I've been looking for related links to this problem but still I couldn't solve it. And at this point I wonder if it's just possible to do that?
Thank you very much

I need securing an Access database. I am about to put the database on a shared drive. I want myself to be able to do anything (of course), my co-worker Paul to be able to ONLY enter information (along with being able to view everything like forms and reports), and my boss to ONLY be able to view everything (form/report wise).
I found this post [URL] .... about how to secure a database. I spent all day doing it, but it didn't work at all! I just got a bunch of errors whenever I tried to do anything, so I deleted the database and re-used an earlier version.

I have recently been experimenting with adding an Access database to a shared folder (in a network HomeGroup) and have it working on two networked PCs. Then tried the same with the database split but I get a path error on the PC joined to the HomeGroup (where the database resides) whenever the backend (tables) are accessed by a form or from the Tables listing. If I however open the backend file directly from the file directory, the tables all open as expected.
The path stated as being invalid in the error message starts with "C:Usersetc..... instead of LAF-PCUsersetc..... so it looks (to me at least) that it is attempting to load the file from the local hard drive rather than the host computer.
Why a split database works differently in this situation than a non-split.

I am going to put my access database on a network drive so that four different computers can have access it. However will user-level security work if I implement it? For example, from one of the computers I implement 2 different usernames and passwords. If one of the other computers tries to access the database will they also be presented with the logon screen?
If not, how can I go about setting this up?

I have made this database for a company that I work at, and I seem to be haveing some problems. I split the Database and placed the "'back-end" on the company's shared drive, however it seems that only when I log in as myself, on any computer, that it works. On other people's profiles, when a form is opened, there is nothing there, it is blank, no textboxes, labels or anything. However, if you use the database window to open one of the linked tables, you can see all of the existing data and cells just fine. I am only 17, and I have used Access for only two weeks, so I may have missed some setting in the splitting, or a database property that is affecting it. Please help me, as I need to finish this DB ASAP.
PS: the folder settings for the shared drive (at least as far as i know...) allow full access, so there should not be an issue there.
Thank you

Hi,
I have been reading throguh various articles and learning a lot from you guys, so thank you very much. This place is a fantastic source of information, by far the best of anything i have found online.
I have a question which i would be grateful if someone could advise upon.
Access 2003. I have 4 tables:
list_accommodation (holding host family address details who offer accommodation to students)
id (autonum)
name (text)
address (text)
etc.....
list_rooms (table of rooms offered by host families)
room_id (autonum)
host_id (number) - joined to list_accommodation.id
room_name (text)
capacity (number)
students (student contact details who want accommodation!)
id (autonumber)
name (text)
dateofbirth (date)
address (text_
etc.....
bookings_accommodation (to hold the accomm bookings)
booking_id (autonum)
room_id (num) - joined to list_rooms.room_id
student_id (num) - joined to students.id
start_date (date)
end_date (date)
This structure therefore enables me to query if rooms are booked between dates:
SELECT bookings_accommodation.room_id, bookings_accommodation.start_date, bookings_accommodation.end_date
FROM list_rooms INNER JOIN bookings_accommodation ON list_rooms.room_id = bookings_accommodation.room_id
WHERE (((bookings_accommodation.start_date) Between DateAdd("d",0,[Forms]![workflow]![workflow_sub_add_accom_booking]![cbo_start_date]) And DateAdd("d",-1,[Forms]![workflow]![workflow_sub_add_accom_booking]![cbo_end_date]))) OR ((([end_date]-1) Between DateAdd("d",0,[Forms]![workflow]![workflow_sub_add_accom_booking]![cbo_start_date]) And DateAdd("d","0",[Forms]![workflow]![workflow_sub_add_accom_booking]![cbo_end_date]))) OR (((bookings_accommodation.start_date)<DateAdd("d",0,[Forms]![workflow]![workflow_sub_add_accom_booking]![cbo_start_date])) AND (([end_date]-1)>DateAdd("d","-1",[Forms]![workflow]![workflow_sub_add_accom_booking]![cbo_end_date])));
and therefore, using the 'booked' query i can therefore find out rooms are available.
SELECT list_rooms.room_id, list_rooms.room_name, list_rooms.capacity, list_rooms.description, list_rooms.host_id
FROM list_rooms LEFT JOIN qry_rooms_reserved ON list_rooms.room_id = qry_rooms_reserved.room_id
WHERE (((qry_rooms_reserved.room_id) Is Null));
----
so, now i have found out that there is a necessity to enable students to share a room (the bookings for a room may not happen at the same time). This means that i have to determine the capacity of a room and therefore if
the capacity is not full, then show as available.
I was wondering what the best approach to this may be?
I have added 'capacity' to list_rooms, but i am unsure as to how to go from there....
Any thoughts and advice woudl be really appreciated.
Many thanks
Phil.

We have a database on a PC located on our network. The database is located in this computer's shared folder. Another database grabs data from this database occasionally. We're running into a problem where we cannot open the DB located in the shared folder (permissions granted) without it being a read only instance even with no users accessing the DB.

can anybody tell me why my colleague cannot add records to a DB I set up on my pc.
i have a DB with 3 tables linked (all one-to-one).
i can add records into it fine on my pc but when my colleague tries on her pc it allows her to enter data but when it comes to moving onto the next record it wont allow her to save the record.
To explain further. there are 3 tables as mentioned before. lets call them Table 1, Table 2 and Table 3. When my colleague uses the form to add a record it wont let her save it as it says a related record is needed in table 2.
any ideas why it works perfectly on mine but not on hers?

Hello,
I have an exrternal shared drive "E:"where I put my be files (which are constantly accessed by users with fe's from different terminals). Everytime
I reboot the computer that I am working on (where the external drive is), I have to set up the permissions of the shared drive "E:" all over again, otherwise other computers have no access to E. Is there a way that I could
fix this and not having to set permissions every time I reboot my computer?
For some reason, the permissions are lost.

Hey folks, me again...
I have a big problem and it's stopping us from rolling out the db to our call-center... cliff-notes at the end...
I have a database that tracks customer calls.
The db files are located on the network in a folder that everybody has access to.
The db is arranged as such:
A backend that holds all the tables.
A front-end for Customer Service Reps with tables that are linked from the backend
A front end for Managers linked in the same way.
And a front end for our corporate folks which is also linked in the same way.
I've tried replicating, making mde's and creating a shortcut on each CSR's desktop. I've also made sure that I use the UNC to link the tables. I've also made sure the db's are shared (I think)
Cliff-notes:
when I have the front-end open on my desktop, and somebody else tries to open it, they get an error. "The file is already in use"
Am I doing something wrong Or am I missing some type of setting??

I'm currently having problems with splitting my database.
The situation as present it:
- I have a shared folder on my laptop, to which i have given full permission rights to a collegue, in this folder is the backend of the db which i split from a database also sat in the shared folder
- I can then go to the front end of my database either on my desktop or shared folder and update tables
- However, this is where the problems start. The copy of the front end that my collegue has (an exact replica of mine) cant access or open any tables. Even if he opens the exact front end that I'm successful with in the shared folder. The following error message appears
"Could not find the file 'D:Testdb_be.mdb'"
the D drive on my computer is where the shared folder 'test' is stored.
Any hints or advice on why this isnt working?
Thanks in anticipation

Hello all:
I have the following code to retrieve doucments:
strPath = "G:CorpCustomer Files"
Application.FollowHyperlink strPath & "" & textbox1 & "-" & textbox2 & ".doc"
This works fine from my computer because the shared drive on my computer is saved on the G drive.
I tried using the code from a coworker's computer, but got an error because her shared drive is : "X:CorpCustomer Files"
Basically anyone can access the Corp server through any drive depends on how it was mapped.
How do I get around this so that it works from any computer as long as the user has the Corp share drive?
Thanks much.

Hi,
Im working on a database that has to be shared by 3 or 4 users. In on of the actions that the database performs, it has to delete records from a table first.
When sharing the database, it always asks the users (using access viewer) whether 'they are sure that the want to delete the records'. Does this always happen? And why? How can I get rid of it? Would it matter if I change it from a table to a query?
Thanx,
Stacey

I've created a database on put it on a shared network drive. I have several people who will need to use this database but I dont want some of them to be able to edit the database in anyway.
Ive tried creating individual user accounts for the database but I don't think I'm grasping how the security works.
When on my machine I'm promted for a username and password but when on someone elses machine they can open up the database with full access.
How do i create individual user security accounts on a database I want to share on a network drive?

I have 4 databases that share 3 tables.
Each database is used for different purposes and other tables which do not relate to the other databases.
My question is: how do I set up the back ends so each database can retrieve and enter data into the 3 shared tables without conflicts??
I know how to split each of the databases to front and back ends but how would I link them all to the 3 tables they share? Should I create one back end with only the 3 shared tables and link the separate back ends for each database???
Any help much appreciated!

We have shared MDE, when second user opens gets message: [B]You do not have exclusive access to the database at this time. If you proceed to make changes, you may not be able to save them later.
The message seems to repeat for each compiled object (Form, Report and Module).
Helptext states occurs when in design mode - but not in design mode!
Any ideas as to how we can suppress the warning?

I'm trying to get one database to be shared by multiple users so that the file on the server is always updated as others add new records....in real time. Is there a way for this to work? What settings will I need?

I just created my very first db... I used the wizzard to create it most of it, including command buttons that permit you to move from the one form to another form/report. I saved the db to a shared drive (two people total accessing/updating it) only to find that the command buttons don't work for her. I created the db in 2003, but she has 2007. If I upgrade to 2007 and convert the db, could this solve the problem? THANKS!!

Hi folks,
I've a BE/FE database where the BE is on the server and the FE on different PCs. I have got linked tables in my FE and the connection between them and the BE is correct; however, users cannot view data entered by others. They can only view data entered by themselves!!
I'm not sure if the records are getting locked that's why they can't see others inputs.
Any help will be very much appreciated,
B
