How To Create Backups/failsafes For Replication Manager/A97?
Jan 22, 2007
I have tentatively gotten an indirectly synchronised database system to work on a testing basis, in the following way:
1. Design Master - resides on network.
2. Replica Master - replica of master, resides on network
3. Local replica on the windows desktop of my laptop (as one of few folders with write authority). These three are managed by a synchroniser running on my laptop.
4. Other people (3-6) also have synchronisers running - managing the Replica Master, and a local copy on their desktop only.
This appears to work. It was done as we did not have access to get a synchroniser process running on a server, just folder access (I am amazed IT accepted this without oversight, anyway..). I would be happy to describe the procedure.
However, does anyone have any advice on potential things that could go wrong and how to avoid them? What problems could crop up? I don't believe database size would be one of them. How about backups? I know that the network is backed up daily and can be restored to any day - but would this method of backup create any problems if restoring? How rare are collisions/conflicts?
Also, is there any limitations to using the Compact utility in Access on either the replica master on the design master? Would this cause changes to get lost?
Would be grateful for advice.
Edit: Addition, just as I was submitting this, my synchroniser appears to have gone into a loop... From the log file:
Time = 2007-01-22 01:23:55 PM
Log Type = Close exchange
Replica = \afsukhofs02N_Dept[Folder names]Replica master.mdb
Exchange ID = {D4C646CE-140A-4DE0-B164-FE924A44C7A3}
Result = Failure
Time = 2007-01-22 01:23:56 PM
Log Type = Cancel exchange
Replica = \afsukhofs02N_Dept[Folder names]Replica master.mdb
Exchange ID = {D4C646CE-140A-4DE0-B164-FE924A44C7A3}
Reason = More than one synchronizer is managing the replica
This looks to be a problem... Is it caused by having multiple synchronisers managing the same replica? Does it work to set them to manage the local one only? Advice GREATLY appreciated. :P
I have used the tree control to acomplish this but the major drawback I have found is it becomes WAY too slow when utilizing large amounts of data due to many embeded loops. Does anyone know an alternative or a way to program the tree control to only add nodes once a selection is expanded?
Basically I want this to operate as a drilldown of infinate levels with the speed of windows explorer. Unfortunatly all the code I have seen requires that all nodes are designated/Created when the form is loaded.
:mad:Is there anyway, I can tell who is making my backups. Is there any thing I can use to find out who is creating a backup. I have sent out emails to the users, but no one will confess who is doing yet. I have 200 users now. I have talk to our IT people, they mention it would take a lot of there time to track it down.
i want to create a batch file that basically backs up the database file i want into a folder as follows
x:ackupsdatabase020206db.mdb
i know that the command to create the folder is mkdir but i want to know how to integrate the data into the folder name so that this batch file can be run in windows scheduler and i dont have to worry about it overwriting the existing folder name.
I receive a report daily. From this report I need to calculate the number of successful backups within a window, and number of successful backups outside a window. The window is 7:00 a.m. The column contains date and time (10/15/2014 7:00 AM). Right now I have written the following query =Date() And > #7:00:00 AM#
I do not get any results even though there are 79 records that fit the criteria.
Wondering if anyone can help me with a problem I'm having with the switchboard manager. What I want to do is open a form in pivotchart view from a switchboard. I've set it as the default view to see if this makes a difference. I've not allowed any other view, no difference. Exhausted all basic property solutions and can't think what else to try. Thinking of either adding a control to the switchboards form in design view and bypassing the switchboard manager or would it be better to put some code into the form that says when open, open in pivot chart view?? Anyone have any other ideas?
I am working on a new system. Have been given Full MS Access but Link Table Manager fails it gives a standard security warning that this new system enforces it says Opening: CProg..FilesMSOfficeOffice11ACWZTOOL.MDE however on selecting OPEN nothing happens. If Cancel is hit then long critical message saying in short " Can't find wizard , syntax error in delerations in VB. Likewise I cannot link to a spreadsheet without using the manager.
Question is there anything I can do or is it the fact that these are options were not installed and it is an administrators job?
Hi, I wonder if anyone could help. I'm in the planning stages of creating a order manager in access for multiple ecommerce sites.
Database will store data on Customers, Inventory, Invoices, Returns, Shipments, Credits, Quotes etc for all sites, and also custom reports. And the idea is to have the database generate the ecommerce sites automatically as static html, which can be uploaded. As the orders come in they will be stored online, and then periodically downloaded into the database.
The reason is we currently have 3 sites running and managing inventory and stock control is the hardest, as currently there are 3 databases controling stock! Also when a customer telephones its difficult to know which site they have ordered from which is unprofessional, and we have to log into every site just to find their order.
Future ideas:- Meaning we are going to setup more sites which will obivously make the situation worse. We also want to branch out in into eBay using the eBay API to download transactions and sales, and will therefore need a place to store the data.
Can anyone foresee any problems with such a system? Any ideas or examples?
There are a few procedures that run when my Access database closes (backing up data, etc.). Since this can take a minute or two to finish (running over a network), one of the users here has started to use Task Manager to shut down the application.
This is not ideal, as the same user has also deleted the backend on more than one occasion. Should both happen on one day, we'd lose that day's updates.
Asking them not to do it doesn't work. Explaining why doesn't work. Telling them not to do it doesn't work. If I ask their supervisor to tell them not to do it, they just deny it. It's starting to look like the backup scripts aren't running, when they work fine for everyone else.
Is there any way of either (a) Preventing them from doing this (unlikely, I'd have thought) or (b) Recording the fact that this has happened.
It doesn't necessarily have to be recorded in Access itself - although that would be ideal - if there's some other file I can access to get the info?
I searched the internet and different forums, but could not find the solution for my problem. In Access 2003 I splitted the database and made a mde file of the frontend. When I copy the front and backend to another computer it cannot find the backend due to the original path is included. To solve this I would like the database to link the backend that is available in the directory of the frontend. No more and no less. Is this possible? I find a lot of questions in this direction, but could not destilate a solution.
I have successfully automated the refresh of my linked tables using VBA (thanks to a post on this forum -- Cool). Anyway, what I would like to know now is this:
If my table collection does not have any linked tables, using VBA, how can I get that list of available tables to show? Assume that I will be connecting to the same database (Oracle) through an ODBC connection. I dont wish to change the connection - just want that window with all tables to shouw up.
this has been "bugging" me for a while. everytime i access task manager it opens for couple of seconds and then disappears. i heard that this was some type of virus and/or spyware related. norton, spyware, and adaware haven't seemed to solve this problem. please help
Hello, Does anyone know how to use a Macro or Module to refresh/update linked excel worksheets in an access DB. I used to delete all the tables then re-add them. There must be a better more correct way. Any ideas?
I am trying to display forms to the user in datasheet view. The properties are set to datasheet as default and Form View to No. They work fine using the database window but are displayed in Form View when using the Switchboard. If the switchboard setting is Open in Add Mode no data is displayed. If it is Open in Edit Mode the data is there but in both cases they are in Form View. I am using Access 2000 and Access 2002. Can anyone help?
I have made a database in access 2003 I have forms, reports etc, which all worked great! then I did a switchboard manager,which took me to two more switchboards and one of them was forms it works great but when I open a form I can not use the find comand, and it does not show all my records but it does up date the table and everything else works great.It is just the find and records on all the forms and only when opened in switchboard when I open them from the database window they work fine.
I have received a replicated db --- that is all (not a master) I want to know if any one has experience in "unreplicating" a db and what steps I take to unreplicate this db. I know (more or less) what replication does for you, but I have never done it !!
Thanks to the many of you who have helpped me get this far. I am finally ready to deploy my database! I would not have gotten this far in just a few months if it were not for your helpful advice. :D One of the final stages is to place the database on the organization's server and to put FEs on each of the work stations. I've read a bit about replication and splitting of databases but I have one question I haven't found answered here...
What is the best time line for doing this?
Do I replicate the data base and then split it? Or do I split the data base and then make replicas of the FE?
Does it matter?
Also - is replication truly needed for all data bases - I have a test copy in which I split the Access file, then just copied each front end to 2 machines and it seemed to work okay. Am I missing something that will come back and "byte" me in the keester?
Many thanks again for previous help and for your answers to this question.
Need some advice on Replication of a backend mdb please. I currently have a client/server app - works great. The users now need to collect data from their internet as well as entering data themselves in-house. Situation... can not link tables from web mdb file IS dept forbids link through firewall. How might I be able to keep the data synchronized when the original backend resides within the firewall on the file server and the other needs to sit on the web server? OR ... is there another approach to allow data entry from both the internal users concurrently with data entry from the web. I'm scratching my head and my deadline is looming. Any advice is greatly appreciated.
I need to hold information in a staff table about a person's Line-manager.
My initial idea was to just have the Staff Table and use the PK of a member who is a Line-manager as a FK in the Line-manager field in the same table for their staff.
I then came across a problem.
I need to be able to select all the staff under a Line-manager. For example a head of department may have 3 team leaders who each manage 10 staff. I need to know all of them, not just the 3 team leaders who are directly managed by the HoD but their staff as well.
As it happens there is no rigidgly defined managment structure per se for this organisation which makes things even more difficult.
I assume there is a reasonably standard way of doing this as all organisations have some form of line-manager/staff relationship. Anyone care to enlighten me?
I have a report based on main database that list all "Sites" by Manager, when i open the report it gives me all the details that I want, what I would now like to do is page break at the end of each manager, in addition the each record as a "completed" and "active" field I only want to show on the report the "Active" Records. ie:- After it reports all the Active marked sites for 1 manager is starts the second manager on a new page, can this be done? and how do I do it?
hey there i want to make a MDE compression/compile but i get a msg that i cant compile a replication how the f*** i remove the replication, cuz i no longer own the master file
I am working with a database that uses an autonumber Data Type in it's tables, this field is set to 'Replication ID'. I am adding records to my table but for every record i add i need to retrieve the newly added primary key (which is the autonumber replication id). If it was a incrementing id i could simply select the MAX value from the field. But seeing as it's a replication id it won't bring me back the latest field. In SQL Server I would use the @@Identity function to return the id. Can anyone help me?
