We now have a business requirement to use SQL Replication to replicate our Live Database Server to a Live Reporting Server. So updates will be in one direction.
I wonder if someone with some experience in this area can give me a rough idea of what I'm getting myself into.
How good is SQL Replication?
How much time am I going to spend reading up before I'll know enough to do this?
What kind of a footprint does it leave on the server?
How much more complex does it make maintenance and DB upgrades?
What's the lag time? If a user updates a record on the Database Server and then emmediatly runs a report on the Reporting Server, will they see that change reflected?
PS: Anyone know what Robvolk is doing these days? I miss that guy. He's one of the few good ones left.
There aren't many primary keys on the tables in the Publishers. If I add primary keys to the tables on the replicated database, when I subscribe again to the Publications, will they disappear from my replicated database (i.e. will the schema be overwritten)?
I was told to do the DTS which synchronizes the data between Informix and MS SQL server. First, I am not allowed to touch the Informix server. Is that possible to do the pull replication subscription from the SQL Express that does the extraction/update from Informix? I tried it out already but I didn't see any publication. umm.. my Informix is not loaded in windows machine. Thank you very much.
Right now we use autogenerated primary keys in various tables of our SQL server 2005 database. Now we have a need to put separate database servers at various remote locations and data will need to sent back to the central server. Some data will be sent back from central server to the remote sites. Data also gets added at the central location.
How can I handle replication when using autogen keys? Can I add some additional column like a SiteID and make the primary key a combination of Autogenerated key and Site ID? Would that work? The autogenerated primary keys are also foreign keys in other tables.
I have read a little about having separate ranges (of autogenerated keys) for various sites but don't think that will work as we already got lots of data in our central server.
Hi all My company is going to open new working centers on different locations of my region. One of the problems we are suffering is that at some locations, the network communications infrastructure is very very very poor. So, in that locations we work with low bandwidths, and connections usually break down.
Because of this, we are thinking in distributing our database. I have been doing some tests on replication, reading the docs, etc... But I am still not sure which replication strategy should we use, and how to organize our database tables to allow replication work properly.
Our offices are going to share some data (a product catalogue, for example) which could be updated an queried from any of the offices. But there is also data which is not going to be shared, as product stocks for each location.
We were thinking on using transactional peer-to-peer replication. But now we are having serious doubts about this since in a previous post (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1525643&SiteID=1) we were told we can't store non-shared data (stock) in the same table as the shared data (products) due to how database behaves when a publication is restarted. We know it would not be usual to republish, but we were thinking on crash recovery.
It would be fantastic if somebody could help us to decide what should we do to organize our database to allow the use of a proper replication scheme.
hi there! i am a newbie with replication. i am trying to implement one, however due to lack of references, there are some difficulties. here are some of my questions, i am hoping anybody could take their time to help me out in details. Thanks and appreciate it!
(1) i could not publish all tables. tables that do not have primary keys are not included, and i need to publish all tables.
(2) tables that i sucessfully published does not replicate the table's primary keys, relationships and triggers, how do i update the subsciber?
(3) for some reason, i could not replicate schema objects - views, UDFs, stored procedures. its giving me an error.
I'm setting up a merge replication for sql ce. Ten guys with windows mobile 5 pocket pc works as service technicians and need to synchronize data in the field.
The backend database is huge and I just want each person to have their own data on the pda and synchronized, they have unique userid's in the database. Is it possible to filter data for each person or do all have to have all data that's in the backend database?
Hi there I sorry if I have placed this query in the wrong place. I'm getting to grips with ASP.net 2, slowly but surely! When i try to access my site which uses a Sql Server 2005 express DB i am receiving the following error:
Server Error in '/jarebu/site1' Application.
Database 'd:hostingmemberasangaApp_DataASPNETDB.mdf' already exists.Could not attach file 'd:hostingmemberjarebusite1App_DataASPNETDB.MDF' as database 'ASPNETDB'.

This is the connection string that I am using: <connectionStrings> <add name="ConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|ASPNETDB.MDF;Integrated Security=True;Initial Catalog=ASPNETDB;User Instance=True" providerName="System.Data.SqlClient"/> </connectionStrings>
The database is definitly in the folder that the error message relates to. What I'm finding confusing is that the connection string seems to be finding "aranga"s database. Is it something daft?
I'm getting this, after upgrading from 2000 to 2005.Replication-Replication Distribution Subsystem: agent (null) failed.The subscription to publication '(null)' has expired or does notexist.The only suggestions I've seen are to dump all subscriptions. Sincewe have several dozen publications to several servers, is there adecent way to script it all out, if that's the only suggestion?Thanks in advance.
Hi,I have transactional replication set up on on of our MS SQL 2000 (SP4)Std Edition database serverBecause of an unfortunate scenario, I had to restore one of thepublication databases. I scripted the replication module and droppedthe publication first. Then did a full restore.When I try to set up the replication thru the script, it created thepublication with the following error messageServer: Msg 2714, Level 16, State 5, Procedure SYNC_FCR ToGPRPTS_GL00100, Line 1There is already an object named 'SYNC_FCR To GPRPTS_GL00100' in thedatabase.It seems the previous replication has set up these system viewsSYNC_FCR To GPRPTS_GL00100. And I have tried dropping the replicationmodule again to see if it drops the views but it didn't.The replication fails with some wired error & complains about thisviews when I try to run the synch..I even tried running the sp_removedbreplication to drop thereplication module, but the views do not seem to disappear.My question is how do I remove these system views or how do I make thereplication work without using these views or create new views.. Whyis this creating those system views in the first place?I would appreciate if anyone can help me fix this issue. Please feelfree to let me know if any additional information or scripts needed.Thanks in advance..Regards,Aravin Rajendra.
In my production box is running on SQL7.0 with Merge replication and i want add one more table and i want add one more column existing replication table. Any body guide me how to add .This is very urgent Regards Don
DBCC OPENTRAN shows "REPLICATION" on a server that is not configured for replication. The transaction log is almost as large as the database (40GB) with a Simple recovery model. I would like to find out how the log can be truncated in such a situation.
Hello,I'm getting the following error message when I try add a row using aStored Procedure."The identity range managed by replication is full and must be updatedby a replication agent".I read up on the subject and have tried the following solutionsaccording to MSDN without any luck.(http://support.Microsoft.com/kb/304706 )sp_adjustpublisheridentityrange (http://msdn2.microsoft.com/en-us/library/aa239401(SQL.80).aspx ) has no effectFor Testing:I've reloaded everything from scratch, created the pulications from byrunning the sql scripts generated,created replication snapshots andstarted the agents.I've checked the current Identity values in the Agent Table:DBCC CHECKIDENT ('Agent', NORESEED)Checking identity information: current identity value '18606', currentcolumn value '18606'.I check the Table to make sure there will be no conflicts with theprimary key:SELECT AgentID FROM Agent ORDER BY AgentID DESC18603 is the largest AgentID in the table.Using the Table Article Properties in the Publications PropertiesDialog, I can see values of:Range Size at Publisher: 100,000Range Size at Subscribers: 100New range @ percentage: 80In my mind this means that the Publisher will assign a new range whenthe Current Indentity value goes over 80,000?The Identity range for this table cannot be exhausted! I'm not surewhat to try next.Please! any insight will be of great help!Regards,Bm
Hopefully this is the right place to post this, I am trying to learn ADO.Net programming using VWD Express with SQL Express... I tried to do the walk-through tutorial on ADO.Net through the asp.net tutorial. The walk-through asked you to download and install a script (check) then it said to open a command window with sql server running (check) and then to copy all of this special script code into to bind the database to the web page (not check). Everything pretty much went down hill after that part. I couldn't get the Update/Cancel/Delete buttons. After that dissapointing attempt at learning I decided to just try and make my own database. All was going pretty well until I try to add the UPDATE/DELETE fields after adding the WHERE clause. No go. So, I don't know if I'm just totally flubbing this up or if this is a common problem. Do I need the two or three pages of custom script like the Microsoft example to make a database work?
1 Hi, I'm a complete newbie at this, and need some help I want to import a text file into a DB. I know how to set it up in the DTS, however when I check the DB each line from the text file is in a seperate row. What have I missed? I want the file just in one row, like its a memo.
2 What do I use to connect to a SQL DB on the web so i can see the DB and all the tables
3 Also if I want to add data to a DB is that done on the server, or do I change my copy of the DB and re-upload
I've imported an access .mbd table into SQL 7.0, and need to know the best way to overwrite my SQL 7.0 table with the new Updated information that is contained in the access table. I've read a little bit about update tables, but is there an easy way to overwrite an entire table without having to specify each row and column?
Ok, not sure if this is where i should post this, but here goes.
I am trying to setup a database to handle RMA stuff at work. I need to be able to access the DB from numerous systems at once. Now i know NOTHING about SQL or any other DB for the most part. Messed around with Access some, but nothing major.
Is there anyone that could help me, explain how, or at least point me in the right direction?
I have MS SQL server 2000. Any help, ideas, or suggestions would be great!!
Hey! I',m totally new to Ms SQL Server. I'm currently trying to import a database from LINUX using SQL+ (Oracle) to MS SQL Server. Any suggestions on how this could be achieved would be most helpful
I need to know how to write a sql statement for VB to Microsoft Access for the following criteria.
TblEmployees only Field to be concerned with is EmployeeID -Its PK TblEmpAttendane has these fields: EntryID - Pk EmployeeID - Fk Date- A text form date validated through vb to avoid hassle Value-A single digit value that can be alpha OR numeric
To get the Date range for the current month I use variables to store the First and last day of the month(in a CUSTOM calendar control).
I have been trying to use this Sql statement(that wont work): SqlString = "SELECT * FROM TblEmpAttendance WHERE Date BETWEEN '" & FirstDay & "' AND '" & LastDay & "'"
I need to: 1.)using the current EmployeeID (from TblEmployees) 2.) find the same EmployeeID in TblEmpAttendance 3.)Get the date range for the current month and year(valid days currnt mo.) -these date are supplied by the variables "FirstDay" AND "LastDay" as seen in above SqlString
4.) Find the Values associated with the dates and EmployeeID
I have a table with 10 records: 10, 9, 8, 7 ... and so on. I want to SELECT the top 3 records starting with the second record on the list (which in this case is 9.) So the result should be 9, 8, and 7. What would be the correct SQL statement for this?
I tried "SELECT TOP 3 * FROM tableXXX WHERE (FieldID<>(SELECT TOP 1 * FROM tableXXX ORDER BY FieldID DESC) ORDER BY FieldID DESC" but sure as heck it didn't work. Can anyone help?
just for understanding a simple iif statement: I like to set a numeric value to 0, if it is smaller than 0. This expression shall be valid over all dimensions for a specific measure
like Iif([Measures].[Provision Ankauf]<0,0,[Measures].[Provision Ankauf] )
it's not working, Pivottable returns ##VALUE everywhere
I have two problems. I am currently using SQL Server express and SQL Server Management Studio Express locally. i have a DotNetNuke website running on the web with IHostASP.Net
Story:
I noticed that my SQL Server 2005 database with IHostASP.net was 350MB. It was only 22 2 months ago and I have had about 100 users sign up. I then connected to my live database via SQL Server Management Studio Express and shrunk the database. No errors and the database was reduced to 24MB - Great I thought!
I went and checked the website and all was great for about an hour then the site went down with the following error:
Error The transaction log for database 'classcampers' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases
Anyone know what to do.
Anyway, I have downloaded a .bak of my database as supplied by my host. However I cant figure out to restore this file back to my live database. What are the steps involved?
Do I create a new local database from the .bak and then somhow restore this back to my live one, or do i apply this .bak file strainght to my live database using SQLMSE. Any tutorials becuase I have been trying to apply this restore all day
Thansk for any advice in advance cheers Albertramsbottom:eek:
Hi, which is current running mostly used version of sql server and what was the previous version? how can we track down a query bad performance in sql server(like explain plan,stats..etc..in oracle)
Ive been learning SQL slowly and I need help for a projet I am doing.
I currently would like to compare identical files in a 2 seperate folder. Not only would I like to compare if the files are the same name, but when they are I would like to compare the file contents.
SO basically this is what I need to do: -Compare file names in folder A with files in folder B -If a match is found, compare file contents -If file contents are same, do nothing. If file contents are different, move file to folder C.
I finally decided to do our ASP application using VB, .NET and MSSQL.
My questions are simple, but I cannot find all the answers, so anything you can offer will be greatly appreciated.
Please explain how licenses (CALS) work with regard to Windows Server and MSSQL. For example, suppose we have 200 clients all logged into our application, but only say 40 are currently active (meaning they are adding data, running reports, etc....), but they are not all clicking the "DO" button at the same time. So how many Windows server and/or MSSQL seats, licenses, CALS, cpu's etc.... (whatever they are called) will I need?
How many users do you think a "well designed" ASP application built using AJAX, ActiveX, VB, .NET and MSSQL can a single cpu reasonably support? This application will serve east coast to west coast with heavy traffic from say 7am to 9am and 2pm to 4pm in each time zone. At what point (or what should I look for) to say, you need more memory, more processors, more servers, etc......????
How does one protect (or build in) a method to deal with index corruptions, etc???? Does that occur in MSSQL? If so, generally, what are causes and fixes?
The application will serve many chapters. Many chapters will be solo (by themselves), but we also expect district wide, where multiple chapters (25 to 75) in one district will use the application. We can expect, during time frames mentioned above, that each chapter will have 200 to 400 transactions per am time and same per pm time.
has anyone had great success with IronSpeed?
Lastly, can anyone suggest some good windows web hosting companies?
Hi i have 2 columns in the same table.....one column retrieves all registered students, the other column retrieved registered students but who have not completed a required survey.
The 2 sql statements are almost the same except that the 2nd one does another comparison at another table....(i.e. where student_id not in (select student_id from other_t).
I am trying to combine the 2 sql statements into a derived table where results will be displayed as follows:
registered students | students(incomplete surveys)
I have a database and in my database there are 5 different tables....
One of the tables is called "dvds" and another one is calles "reports"
What I want to do is, I would like to copy and paste everything in "reports" (column name: dvd) to "dvds" table (column name: name).
And I wan the SQL parameter to check everytime before it writes to "name" column in case that entry is already there. If the entry is already there then ignore and do not write, if it is not there then write it.
I am very sorry about my english and my knowledge on SQL.
Can anyone please help me to product this SQL command?
I have questions regarding theses files TRN, LDF, MDF and BAK.
I have a maintenance plan that backups the .TRN and .BAK everynight in a folder e:/mssqlsrv/MSSQL/Bakup. When I look at the date modified in windows explorer they are exactly like I programmed it in the maintenance plan.
Now when I look in the folder e:/mssqlsrv/MSSQL/Data I see the .LDF and .MDF files and they are way out of date. How do they get copied there? With the maintenance plan? What is the difference between the TRN and the LDF?
How does a restore work? I am so confused? Please explain to me?
I just went through Steve Lasker's slide show on Everywhere (which was very informative) and noticed that when he setup the connection to the Everywhere database it had a .sdf extension. However, when I look at my database using SQL Server Management Studio Express it shows me as having the standard .mdf and .ldf files and *no* sdf file. I thought for a moment that I might be using Express but when I look at the connection properties of my (or what I think is my Everywhere) database I see:
Product Name: Microsoft SQL Server Desktop Engine
Product Version: 8.0.818 SP3
Instance Name: MICROSOFTBCM
If I look at an Express database, I see connection properties of:
Product Name: Microsoft SQL Server Express Edition with Advanced Services
Product Version: 9.0.2047 SP1
Instance Name: SQLEXPRESS
So it appears that I am not use Express but yet, no .sdf files. Can someone tell me about the different file extensions and which ones I might be using? I would assume with the product name of "Microsoft SQL Server Desktop Engine" I am using Everywhere - but maybe not. Please advise.
