Just wondering if someone can tell me exactly what is happening during the "synchronizing" phase during db mirroring. Basically I have 2 questions regarding restoring and synchronizing.
1. Assuming there is no initial mirroring setup. A backup is taken from serverA. After the backup (and before the restore on serverB), there are several INSERTS being performed on the serverA. After which, the backup is restored to serverB and the servers are mirrored from A to B. Does the synchronizing state mean that all transaction logs are being synchronized and serverB will now have those newly inserted transactions?
2. Does this mean that as long as the transaction log is not truncated on serverA, serverB will always have an exact copy of the serverA database?
I did a full backup of a db from one server(Express2005) and trying to restore it to a different instance of SQL2005 on the same development machine. (Also had some fulltext columns if that means anything)
Many failures but finally got it to report all was successful except the icon in Object Explorer shows (Restoring...) with no indication of any real activity going on. It's a tiny database with hardly any data in it.
Just not sure what the heck is going on there. It also won't let me into the database until this the (Restoring...) goes away.
I have 2 distributed databases which need to be synchronized at regular basis. I plan to write a service that does it. But I'm just curious how to do the update incrementally. Thanks
I have a website that is running on the intranet and on a notebook. I have a notebook that is not always connected to the internet.. when it is not connected, it will read in some data from a barcode reader; and when it's connected, it will synchronize the data with the db on the intranet.. any idea on how to achieve this?
Hi All, I want to do SQL Server DB Synchronization. The scenario is like this.. DataBase is presently on SQL Server 2005, When end user click on button or on some action event all data to from the server should be fetched & should be saved on client m/c. Afer that when user click on button or on some event, DB should be synchronized. i.e. if there is any change in Server Data, client data should be automatically update... How can i achieve this using C#.. Plzzz Help!!!!!
Once I go to client site (where production DB is located) I want to generate a DataSet (which I am able to do) and compare this DataSet with the DataSet created when I read in the XML file.
## 'read in XML file XMLDataSet.ReadXML(Server.MapPath("xDataDictionary.xml")) ##
There is a unique identifier in the table and XML file called 'FieldID'. What I need to do is compare DataSet (from Production DB) with DataSet from XML file.
If there is a 'FieldID' in the DataSet from XML file that IS NOT in DataSet from ProductionDB I want to insert this node/row into the database.
I was wondering if anyone knows if there is any software available or if it is easy to implement the following.
We are running a SQL Server database locally in house and also have the exact same database running on a hosted webserver. The data changes on both versions of the database daily and what we need to do is figure out a simple easy / cheap way to have the two databases synchronize with each other every evening so that the data is exactly the same every morning.
Hi Guys: I am trying to synchronize my home sqlserver database with a database on my web hosting company. I am not really sure how to go about it, any suggestions?
I am using SQL Server 2000 Ent/Dev edition. I have a 2 identical database in 2 different servers and i'm required to synchronize both database. However, i need to exclude some of the tables in during this process.
I tried to search this forum but can't find any solution. How can i perform the above task? BTW i can't use trigger as i have more than 100 tables.
Hi, I am having this scenario; I have 2 SQL Server 2005 databases, they are basically identical in structure. The first one is used by my web application and the other is by desktop application ... I created the web db for security reasons ,.. i dont want online users to have access to the major backed (desktop db) directly so the web app is writing to the web db ... now, I want to update my major backend as transactions to the web db happen and vice versa to keep the users of both applicaions happy ... Is there a good design patterns for that? I am thinking of using db triggers for this but not sure on the implementation details ... Your help is much appreciated
I'm currently working on a Database Synchronization project and I wondered if anyone had any ideas other than what I've got so far. The context of this project is that we have a central server which stores data for 10 different locations in a consolidated database. Each store contains a replica of that database, but with only data relevant to their own operation.
Store owners can change data at the store level or chain owners can change data at the central level, but for either change the other level has to be notified. I currently have 2 ideas on how to do this.
Note: I am using MS SQL Server 7 for the central, but MSDE (Desktop Edition) for the store levels. So, replication from the store to the server is not available. I think I need to actually code this on my own.
Our company has an enterprize site (a very large one). From time to time we need to make changes in it. In other words, we had to synchronize one database (local where we make all changes) and database on hosting. So, we did it manually (wrote scripts and inserted them in database on hosting). But as the databases grew it became impossible to synchronize everything manually. So we need some tool which could cope with this task. The problem is that, as I know, there are many tools which can do it, but we are tight in time and can't evaluate them all. Please share your ideas on what tool is worth evaluating?
I am not a SQL developer by any means. I have a application to build for a Valet company that will require a laptop on site with no internet connectivity to function locally. There will be about 15 locations that all operate independently. After the day is done, the laptops will connect to the internet and upload all data to a hosted SQL server on the internet for centralized data storage and reporting. After a successful upload, the client database will be purged and start fresh the next day. Should this be doe with MYSql on the client and SQL server at the data center? I have some people recommending Progress database but it is expensive. I am out of my element when it comes to syncing db's so any advise is appreciated. Thanks-
Dear All, I’m having three databases with same data in three different locations. Now three users adding records to the particular databases respectively. I want all the data from server A to be there at aerver B and C. all the updations at server B should be there at Server A and server C. as well as same updations at C also. It is not possible to implement replication as all the servers are at long distance. How can I update every database with the other server’s data? I’d like to update day wise. Is there any tool to generate script on that particular date period? Experts, I think you understood my scenario, please let me know the tools or list of best possibilities for me.
I’m thinking of Incremental backup. Guide me in this scenario.
I have two SQL Server Database, one is at my company and one is at my company's customer. There are two related databases and two related tables in the servers. When I make a change in the table at my database, I want these changes to be done at the other server. I mean the related tables should have the same records all-time. I made a search and found that "Linked-Servers" is a good idea in this scenario. I made a linked server and run the following query in the Query Analyzer;insert into SAMPLE_LINKED_SERVER.SAMPLE_DATABASE.dbo.SAMPLE_TABLE(id,name) Select id,name From MY_SAMPLE_TABLE Where id Not In (Select id From SAMPLE_LINKED_SERVER.SAMPLE_DATABASE.dbo.SAMPLE_TABLE)This query works as I wanted. But I want this process to be done automaticaly without user interaction. Should I use Trigger? Do you suggest using Linked Servers?Or is there any other methods to make synchronization between two SQL Server Database?If I cannot find a good method in SQL Server, then I will be forced to make this synchronization by writing .NET code, but that would be difficult I think. Any suggestion and comment is wellcome.Thanks in advance.
We need an architecture in which one office is in pune and other in mumbai,
principal server is in pune and mirrored in mumbai,
now we need an architecture in which mumbai user will performing read only operation from mumbai server (local server )and write operation in pune server(remote server)
and pune user will be performing read and write operation in pune server(local server)
now when link between pune and mumbai goes down, mumbai users will not be having acess to pune server so at that time mumbai user will not be performing write operation in pune server (local server) and when link goes up we want mumbai server to get updated with pune server.
how this is possible or any other different solution to this, what mandatory is we want mumbai users to perform read operation from mumbai server ONLY.
Hi there, I need to create a synchoronization with the Server Mobile (displayed in the Pocket PC emulator) once the website (SQL server Database) is updated. Is there any coding available? How is it possible? PLSSSSS HELP ME....
Hi all, Well, I have created an applicatin in asp.net and it connect to MSSQL database, and it work fine.
There is another application which was developed in Oracle and the database is oracle 8i.
Well, wat i want is whenever a form is submitted from the asp.net application, the data is inserted in the MSSQL server database and the Oracle8i database also.
There is some strange behaviour i've recently noticed while watching synchronization progress in Replication Monitor on SQL 2005 Server Standard with merge replication configured. The merge process seems to repeat several times.
This is the initial synchronizaion (reinitalization at the subsciber). Client is using Microsoft.SQLServer.Replication objects from .net framework assemblies.
The synchronization starts normally (status is "Running"). The last message of selected session box shows (among other messages): "Beginning evaluating partial replication filters" then "Finished evaluating partial replication filters" and finally "Merge completed after processing xxx changes... etc." after a few seconds. Status changes to "Completed" and then... the merge process starts again!! "Beginning evaluating partial replication filters" etc. And this repeats about 15-20 times.
And so whole process takes about 15 minutes instead about 45 seconds to complete initial synchronization. The number of changes is "Merge completed after processing ..." never change since the first such message.
Is this some bug in web synchronization or some invalid configuration setting? Why does merge process repeat itself so many times??
All- I'm a newbie working on a VWD project. A couple questions arose when attempting to work with a project's dataset and its underlying SQL Server Express database:
Is it true that when changing the schema of a database in SQL Server Express through the VWD Database Explorer, one must take care to manually make parallel changes in the dataset? For example, if you make a relation between two tables in Database Explorer, you must do the same with the counterpart tables in the dataset? For example, I find that if I delete or create a relationship between two tables in the database, I must manually do the same in the dataset.
I have a SQL Server 2005 Compact Edition database that synchronizes with a SQL Server 2005 Standard database via merge replication.
The problem I have is when I cancel a synchronization, the database is left in such a state that I cannot add any new records. I dug around a bit and have found that in the INFORMATION_SCHEMA.COLUMNS view, AUTOINC_MAX has been incorrectly set to the same value as AUTOINC_MIN for the primary keys, which explains the 'out of range' error I get in my program when running off such a database.
In contrast, a non-corrupted database has AUTOINC_MAX set to AUTOINC_MIN + 999, presumably because of my subscriber identity range of 1000.
If this is the only thing that has gone wrong, all I need to do is programmatically set the AUTOINC_MAX values to AUTOINC_MIN + 999, however I can't find out where to do this (and INFORMATION_SCHEMA.COLUMNS is a view so it can't be updated obviously.)
I have also heard that 'compacting' the database may help, but I don't know how to do this either!
I did tried the encryption on server "A" for database "AdventureWorks2012". Then I tried to restore to server "B". There was the certificate issue, and I thought "of course : it's encrypted ! Let's deactivate it". So here I go "ALTER DATABASE AdventureWorks2012 SET ENCYRPTION OFF".I look at sys.databases : not encrypted.I backup using no encryption, I verify using msdb.dbo.backupset : not encrypted.
I move my backup to my other server where encryption was never configured (so no certificate, nothing...), and I have the error : Msg 33111, Level 16, State 3, Line 1
Cannot find server certificate with thumbprint '0xFA130E58C999C4919B8975999C83A75A403B11D8'. Msg 3013, Level 16, State 1, Line 1 RESTORE DATABASE is terminating abnormally.
I want to restore a database (from an encrypted .bak file) - but *not* over the live original if you take my meaning. Encryption is the standard AES-256 that comes with Sql Server 2014 btw. I don't want the original touched/altered in any way. I would like to capture a success message if possible.I can extract the physical device name of the database in question using the following code:
SELECT physical_device_name, * FROM msdb.dbo.backupmediafamily WHERE media_set_id =(SELECT TOP 1 media_set_id FROM msdb.dbo.backupset WHERE database_name='MyDatabase' AND type='D' ORDER BY backup_start_date DESC)
I would like if the newly restored database was rename to something different than 'MyDatabase' (as shown above) and has different logs than the original. If possible, and capture a success message when restored.
I have a Subscriber database updated using transactional replication and want to create a copy for development & testing. The Distribution database is running on the same 2005 instance as the Subscriber and the Publication database on another server running SQL Server 2005.
If I use a TSQL script to run the restore, the database is restored to a usable state but I get the following messages:
Msg 15247, Level 16, State 1, Procedure sp_MSrepl_check_job_access, Line 112 User does not have permission to perform this action. The replication agent job [job name] was not removed because it has a non-standard name; manually remove the job when it is no longer in use. (I€™ve removed the job name from the message) RESTORE DATABASE successfully processed 46219 pages in 935.413 seconds (0.404 MB/sec).
It looks like an attempt is being made to restore replication information too. I note that the RESTORE statement has a KEEP_REPLICATION options which implies (I would have thought) that by default the replication information is not be restored.
Incidentally, before implementing replication, backing up the live database and restoring the backup to a new database took < 7 minutes but running the same process with a Subscriber database backup takes about 15 minutes.
I€™d be interested to know if anyone has any idea what I€™m overlooking or doing wrong.
1) We have got the database dump (.bak) file in one machine and we need to restore this to another machine where the SQL server (version 7) is running. But in the restore option there is no way to choose any mapped or shared drives in remote machine. Any pointer to resolve this problem?
2) Can you set up a database if you have the .mdf and .ldf files?
I am running SQL 7 on two seperate NT4 servers, a production server and a standby server. Both servers are configured for Mixed Mode authentication. If I back up a database on the production server, do I also need to back up the master database and restore it. My reasoning behind this is that users' login details will be held in the sysxlogins tbl in the master, while their access rights will be held in the sysusers tbl in the database I am backing up and restoring. If I back up and restore a database without backing up and restoring the master db as well, will the connection between the system login and the database user be broken. Any comments/suggestions would be appreciated.
Currently have large database in three devices, named Cabinet cab2 and cab3. Cab3 device has been expanded twice. We are upgrading the hardware and would like to get the database into one device named cabinet and clean the mess up our vendor initially created for us. Any Ideas/steps on how this could be accomplished??? TKS Jerry
Using SQL 7.0, has anyone backed up a database and restored on to a different database without the device files being moved around.
For example, With SQL 6.5 we used to backup PROD (source) database and restore to TRAIN (target) database. It worked just great regardless whether the databases are located on the same drive or not. We loved it and used it to refresh TRAIN from PROD on a weekly basis.(using sql Enterprise Mgr)
However, in SQL 7.0 when we attempt this procedure the database and log files of the TRAIN (target) are getting relocated to the drive location of PROD (source) database. Very strange.
Though thru object transfer i.e. import ,we can import data from PROD(source) to TRAIN (target) database, but it is very slow and takes lot of time and performance degrades for source database (PROD)
Any input on above will be appreciated if backup / restore thru enterprise mgr or TSQL procedure works in SQL 7.0 for restoring another database which is also on different drive i.e PROD (source) database on drive C and TRIAN (target) database on drive E.
While this may be in the wrong forum, I thought that I should try here first.
One of the developers that works for this company would like to restore a sample database to the SQL server after installing our software.
Is there a command line command that can be issued to restore/create a database with a file (.bak) of an SQL database (sample)? If this can't be done, can it be done with VBScript or something similar?
SQL is not my strong point, and neither is development. Any help would be appreciated.
