Running Back End On A Linux Server
May 12, 2006
Hi Guys,
I hope this isn't too stupid a question, but I have a db that needs to be accessed from several workstations. It is currently a split db, with the backend residing on one of the workstations in the workgroup. I was wondering if it possible (as I am looking at buying a server) to "house" the backend on a Linux machine? The main reason I ask is that Linux is <$100, but MS Server is >$1000. Does the server need to be able to run the program? If yes, is there any way around this?
Thanks in advance for your help!

Hi, I am not sure where to put this thread hopefully someone here can help me.
I have spent a good deal of time developing a very effective access database for a client. It is split into a front end and back end and connected using the Linked Table Manager when necessary.
The front end is quite loaded with queries, reports, forms, macros etc and the back end simply has the tables.
The front end is about 15 mb and the back about 8 mb.
Current set up is a small workgroup network with about 4 -5 consecutive users at any one given time.
I am looking for some advice on how to set up or facilitate getting the backend on the internet so anyone with a front end can access it outside of the LAN.
Today I set up an account with WebDrive which can connect to and assign a drive letter on your pc to any FTP, HTTP site.
I made the connection with WebDrive and using the linked table manager successfully linked the tables on my local machine to the back end on the FTP server - and actually ran the database at a pretty good rate.
I noticed however that it was downloading the backend to my local pc and once I closed the (a) form it was uploading the data back to the server? Very slow and often threw errors.
This of course is not what I wanted. Has anyone heard of doing this? Any work arounds or setting params would be greatly appreciated.
I have been told to create the DB in ASP but I do not have any idea on how to do that whatsoever...
Any advice or insight would be awesome!
Thanks!

Hi
I have 5 PC clients and a server.each user upon shutting down his PC,is prompted to send all the information inside a table "Patron" to a table inside the server.That way each user backs up his information to a table inside the server and at the end of the day,the table on the server side contains all the data from the 5 PCs.I am new to access,can anyone guide me through the steps I need to accomplish this project?
thanks in advance

We have offices in other states that need to be able to open our data base. Due to the line speed it is extremely slow linking to our backend. Is it possible to have duplicate backends that can be merged, lets say over night or at the push of a button.

So the database I have right now is split, with the back end on our server. Everything has been going great, however there are several second time delays when loading large forms, queries, etc. I've heard that moving the back end to an sql server is the way to go for speed.All forms and queries are on front end of database. Tables are located on the back end which is sitting on the server.

I have a database with a front end and back end (tables on the server) that was recently converted from Access 2003 to Access 2010.
For some reason the back end keeps hanging and I have to constantly compact and repair and there has been major data loss on a regular basis.

I'm experimenting with MS Access, and I've successfully split an MDB someone created into two files. I can access the database from 2 computers at once using the front end file connecting to a file server which hosts the _be.mdb file.
Could the _be.mdb file theoretically be on a NAS without any computer attached, or is there some runtime or full version of Access that needs to run on the machine with the back end file?

Can anyone tell me how to get a running balance on a report. I know how to create a running total, by setting the "running sum" property of a text box to "Over all".
I can't however see how I can adapt this to give a running balance (as in a bank statement for example). Attempts to do so end up in failure!!
Many thanks in advance.

Using A2002 or A2003, trying to convert an app from Jet to SqlServer
i am using DAO rather than ADO
this statement causes an error
Set rs = dbs.OpenRecordset("tblconstants", , dbSeeChanges)
the error is
error 3622 - must use dbseechanges on a sql server table with identitiy bit set
alternatively
Set rs = dbs.OpenRecordset("tblconstants", dbOpenDynamic)
produces error 3001 - invalid argument
(Note: i've got another app, in A97 that works with sql server tables without any additional parameters )
Set rs = dbs.OpenRecordset("tblconstants") works in A97
------------------
any idea what do i need to do please

Hi. hope you can understand my english.
I have 2 SQL Servers.
Is there some way to set to which sql server connect the .adp (or .ade) via code??
Now I have 2 sql servers (development and production).. but soon I will have more server at production in different cities. All SQL Servers have different names. Same databases names but the servername are all different.
So I have to configure the connection of the .ade in the the development server. Then when I want to send and upgrade to one of my clients, I have to go to his city and manually reconfigure the .ade to connect to his SQL Server.
This problem would be solved if all SQL Servers had the same name, but this is not my case.
It would be nice to have a config.ini file or something like that where the .ade could read the name of the server to connect to.
Is it possible to implement something like this.
Thanks in advance.

I've never dealt with SQL Server, and have no working knowledge of it. Is it possible to upsize my db without it? The server that we have uses Windows 2000 Server as it's OS, would this be capable of housing an upsized db? I was tols that MSDE is only capable of about 15 concurrent users, and I will be having +-100 concurrent users on this particular db. Is there another option?

Hi guys, its been awhile. I inherited a database thats an MDB and I need to get it on to sql server but I am having problem with this query, can anyone help please. Its suppose to give you the month and year when you click on it, you just put that in and up come the results on a query or report, now I have something similar to this but the code is very different.
SELECT DISTINCTROW Format$([Main Table].Date,'yyyy') AS [Date By Year], [Main Table].[Violation Type], Sum([Main Table].Loss) AS [Sum Of Loss], Count([Main Table].[Violation Type]) AS [CountOfViolation Type]
FROM [Main Table]
GROUP BY Format$([Main Table].Date,'yyyy'), [Main Table].[Violation Type], Year([Main Table].Date)
HAVING (((Year([Main Table].[Date]))=[Please Enter the Year]));
This gives them a dialog box which ask them for month and year and they enter it in and they get a generated report or form which gives them their results. But when I transfer this to SQL it gives me error message cause Jet SQL and SQL Server dont exatly speak the same language, I mean SQL server doesnt know what Format$ is I guess thats something ACCess comes up with on its own or something, I dont know. HELP PLEASE!!??

Hi,
I have a database which is secured via a workgroup.
I have just ran the database splitter to seperate the data into a back end. But now I can open the back-end directly without any password.
How do I ensure that the back end is still secured when doing this?
Thanks,
Adam.

Hi folks,
I've built a few simple databases in the past, but never one where security was required. Now someone wants a database where access to certain areas is limited. Everything I read about Access Security here makes it seem complicated, and flaky, so I was wondering about doing something simpler ;
1. Make the Back End password protected so no one can open it
2. Make the front end an MDE. Put certain forms behind a form which prompts for a password. Store the password in a table to allow it to be changed if required.
So this looks like a crude method to me, but it is for a small user base, where the manager needs access to certain info which employees shouldn't see. I suppose if an employee was so minded, and put in some effort, they could get around the simple password-protection, but is it worth setting up proper security for a small project ?
Can anyone offer any advice on how much more secure the database would be if I did it properly ?
Thanks,
StepOne

Hi,
I come with a mainframe background so please excuse me for my Ignorance on Ms-Access/VBA. :(
I am in the process of developing a solution using Access/VBA. I want to include custom Database Backup and Restore facility within my Application. :rolleyes:
For example:
Say I take a backup of the Database before the monthly update and store the backup (in a folder).
After the update, if a user thinks that the monthly update did not go as he was expecting (this could be because of the data that he fed into the application) - I want to give a option asking user if s/he want to rollback to a previous version of the database. (This will be similar to Windows SYSTEM RESTORE facility).
The Database sits on a network drive (mostly this would be used by one user for the update part and may be 1-2 users who would be viewing the reporpts that come out of it)...So I can safely say it is a stand-alone, single user system.
What I would to ask your help is on following.
1. While my application is running how do I do the restore?
Or do I have to have a seperate application which performs this (ie., restore/backup) operation?
2. While my application is running, Can I take a backup copy of the Entire Database?
Any other hints/help regarding this would be much appreciated. :)
TIA,
PW.

For some unknown reason I am unable to open the back end of my database, as far as I can see it has not effected people adding data through the front end, I just can't open the back end.
I checked the file format and it has changed to a LDB file, no idea what this is or why it has changed, any ideas on what has happened and how I can fix it?

Hi friends,
I think I am having some problem with my back end and frond end files. I have a mde file that anytime I enter new data or change some things in the old clients file, it does not update on the mdb file. Anytime I need to change forms or report or any thing at all, I am suppose to copy the BE file and the MDB file to my workstatio, remove the table link, make the changes I want to make on the design mode and then import the files back to the live copy of the mdb file then make another mde file to work with. But When I copy the BE and the MDB files, I don't have the updated client list or new client just added. So as not to affect other users, I can not make changes in the MDE file and even the MDE file will not even let me make any changes in design mode. I don't know If I am making sense but any help will be appreciated
thanks

I am having a trouble with a multiuser DB. I have split it using the Splitter Wizard and have put a copy of my FE to a second computer and relinking its tables. When I opening the bound form in computer 1, computer 2 can not open that form and sometimes computers lock and had to restart the machines. But if I open that form in computer 2 first and then the same form in computer 1 , it works fine. I have set full sharing to computer 1. I am using Access 2007 and Windows VISTA.
Both have FE, the BE is located in a shared folder with full permissions in C: in computer 1, the FE of computer 1 is in that same folder. Both computers are connected via a Cat5e Cable.
FE in computer1 table links to c:databaseBE and computer 2 links to computer1_IP_Addressc:/databaseBE
Can anyone help me please!!!
I'd appreciate it a lot
Thank you!!

Hi there, :cool:
I've one FE & BE related question here. Ok first of all I've BE in server and each user have copy of FE in local PC. But I've one problem with linked tables between FE & BE.
Is there a way that FE can programmatically create connection to BE linked tables or user is able to link those tables manually, if FE can't find/connect to linked tables in BE? Or do I just have to manually configure each users FE linked tables?
All replies are welcome and well approciated at all costs! :D

I am working on an MS Access database that will connect to an MS SQL db back-end through ADO code only (no constant connection), so I am using connection strings when it is needed to pull back data, other wise it is not connect to the back-end database.
I am trying to get the code correct, and I believe I am close but missing one piece. Here is an example of what I have so far:
--------------------------------------------------------
Dim cat As New ADODB.Connection
Dim cmd As ADODB.Command
Dim rs As ADODB.Recordset
cat.ConnectionString = "PROVIDER=SQLOLEDB;SERVER=KCNTLBASE;DATABASE=Test;U ID=testuser;PWD=testpassword"
cat.Open
Set cmd = New ADODB.Command
cmd.ActiveConnection = cat
cmd.CommandType = adCmdText
cmd.CommandText = "Select MttrNm from dbo.Page0"
cmd.Execute
Set rs = New ADODB.Recordset
rs.Open cmd 'cmd.Execute
MsgBox rs.RecordCount, vbOKOnly, "Test"
'Debug.Print rs.GetString
cat.Close
-------------------------------------
I believe my error is at this line:
cmd.ActiveConnection = cat
I want the cmd to use the connection string. But all the help I find is just the code "CurrentProject.Connection" which only connects me to the MS Access database itself.
Does anyone know what I need to place here so that the cmd is using the correct connection string to the SQL back-end?
Thank you for your time.
