I'm in a project to replicate a database from the production environment to another sql server.
The idea is use it for some biggest querys because in the production database we had experimenting various problems. What is the best way for do it? Transactional replication? Log Shipping? I'm reading absolutely everything but I can not get decide.
Both servers are SQL Server 2008 R2 and they are in the same LAN.
We have many users with a mobile application running SQL Mobile and using merge replication to get data back to the SQL 2008 R2 database. This has worked very well for many years.
We now have a requirement to have this data reported on using Reporting Services. This is where it gets messy.
Due to a limitation of Report Builder(see this blog) we cannot provide access to users for creating their own reports. The report database is remote from the host and there is no VPN.
We hit upon the idea of creating an almost identical publication but the articles as read-only. It was only after this was done that we started having trouble with our existing mobile users.
It seems that a published article is EITHER Bi-directional OR Read-only even if they are in separate publications.
I then thought of using Transactional Publication but this too is blocked on creation with "automatic identity range support is useful only for publications that allow updating subscribers"(Merge and Transactional publication are mutually exclusive)
So in the final analysis is there a way for me to have merge replication AND some other form of SQL replication/data transfer that can have the same data transmitted readonly to a separate full SQL server database?
When creating the snapshot I didn't choose the option copy non-clustered indexes. I created some indexes manually on subscriber database. Replication failed later with some issue.
so reinitialized with new snapshot but all the indexes are gone from the subscriber database.
How to keep the indexes without dropping from subscriber database whenever we reinitialized with snapshot
i attached adventure works in sql server 2008 and it showing as read only ,make it read write or remove read only tag from database.

View 0 Replies View RelatedI have a requirement to read a value from table and increment it by 1. There can be multi-threads doing the same operation and would need a ROW LOCK so that read and write both are atomic. How can i put an exclusive lock on the row before I read the value from the table.
CREATE TABLE [dbo].[tblOnboardingSequence](
[OnboardingSequenceID] [uniqueidentifier] NOT NULL,
[Name] [nvarchar](255) NOT NULL,
[NextNumber] [bigint] NOT NULL,
CONSTRAINT [PK_OnboardingSequence] PRIMARY KEY CLUSTERED(
[OnboardingSequenceID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
My Stored Procedure has below logic
DECLARE @NextNumber BIGINT
----------- Acquire row lock here
SELECT @NextNumber = NextNumber FROM tblOnboardingSequence WHERE Name = 'TPO'
UPDATE tblOnboardingSequence SET NextNumber = @NextNumber + 1 WHERE Name = 'TPO'
----------- Release row lock here
I would like to have a row lock for the row having Name "TPO" before SELECT query and release after UPDATE query.
What si the best way to deal with this?
The below query will read the data in XML format but any query to read from each column of XML tags easily?

View 4 Replies View RelatedI have a stored procedure that updates a table. I also have an UDF that allows dirty reads (nolock).
What's the precedence level in SQL server? If I add xlock,rowlock to the update statement, will the dirty read wait for the update transaction to commit, or will it perform a dirty read regardless of the locking scheme in the update statement?
I have the following query:
Select p.Id [SenderId], p.Username, up.PhotoId,
CASE
WHEN mr.ReadDate is null then 1 -- New message
ELSE 0 -- Message has been read
END AS NewMessage,
p.LastLoggedIn, p.LoggedIn
[Code] ....
The above query returns me all messages (inbox functionality) that have been sent to mr.ReceipientId, the issue I have is when I send another email to the recipient the readdate field will be null, and the other emails linked to the recipient which have also been sent via me will have a readdate date. This causes duplicate rows to appear due to the case statement, I'm trying to figure out if / how it is possible to only display the one row per conversation and set newmessage to 1 if there is an un-read message otherwise show 0 ?
So instead of showing this:
2Person102015-07-26 17:07:24.9370
2Person112015-07-26 17:07:24.9370
I'm trying to get it to look like this:
2Person112015-07-26 17:07:24.9370
Or if we have no new mail (read date is not null) then it will appear like this, and I can confirm when there is no new mail it works as expected.

I am inserting updating few tables from snapshot and reading same bunch of tables from reporting using readcommitted . It is showing some deadlocks i think it is write in this situation as " x" is not compitable with "s" ,"is".

We have a SQL Server 2008 that is being replicated transactionally (log shipping) onto another SQL Server 2008.
Can we report against the replication slave without disrupting the replication process? I have been informed that the slave server needs exclusive access to the db in order to apply the transaction log.
If this is the case, are there any configuration changes which would allow us to report from the slave without impacting replication?
I am trying to configure replication using a script. I created the distribution database as well as the publisher. Now, I am running the stored procedure in one of the subscribers to create subscription. However, I keep getting the same error over and over again. The error reads:

I'm looking for a process to archive data through replication. I have nightly job that purge records in few source tables(publisher) retaining only 3 yrs data. I have archive database (subscriber) that contains prior 3 yrs data and current 3 yrs data.
Before nightly job DELETES records in Source table i want to STOP replication so that the delete is not replicated in archive database. After the job completes i would like to TURN ON replication so that any new inserts and updates in Source will ONLY be replicated in archive database.
My DBA tested this but after last step of turning replication back ON archive database is sync'd with source table.
There are around 70 tables where 30 of them are transactional tables that needs record purge. Developing ETL process is possible but tedious.
How do we know our schema changes will propagate to subscriber without breaking the replication? Is there any t-sql command to find out the option true or false?
View 2 Replies View RelatedSQL Transaction replication, specifically SQL backup and restore Transaction replication. So Scenario,
S1 = Primary Server 1
R1 = T - Replication Server 1
R2 = T - Replication Server 2
So we have S1 replicating to R1, and we want to build another subscriber which is R2.
Can I take the Replicated Database from R1, backup it up, then restore it to R2, and create the publication/subscription?
Will that work? if not, is there an easier way to avoid the snapshot? the reason i ask this is because we do have replication snapshot, but takes long. One of my Colleagues stated he tried this, however replication made duplicate rows on R2, which is why he had to use replication snapshot.
We have a central office with a SQL2005SP4 server (yeah, I know... old as heck) that's the main database and it has multiple subscribers in regional offices. Well... one of the regional offices server is failing, and it needs to be replace.
The original server is an ancient Win2003 86x
The Server team will build a new Win2008r2 64x, and use the same name and IP address
And I'm tasked with the SQL part.
I'll be installing the same version/patch of SQL, but 64x instead, and migrate all databases, including the system databases.
How do I handle replication? Do I need to reintialize from scratch? or can I just use the backup as a starting point?
Is there a way to force the snapshot to use a format file when bcp'ng the data to the subscriber?
The publisher and subscriber schemas are slightly different. Mainly added columns to the subscriber.
We have a post snapshot script that updates these additional columns on the subscriber.
I'd like to force the snapshot to use a format file, so it doesn't error when initially loading the data to the subscriber.
Is this possible?
Currently, we are on SQL2008R2 EE SP1 CU13 across the board.
We are planning on upgrading the primary SQL server to SP3.
Question: Will transactional replication continue to work properly even if the Publisher is upgraded to SP3 but the subscribers remain at SP1 CU13 ?
We are approaching the "go live" date of a big application upgrade, so while the application is being upgraded i was asked to lock out all users and backup all databases and make sure the data isnt changed during a period of time
It turns out, as one of my databases is being replicated to another server, i cant put that database in read_only mode, or restricted_mode, without removing the replication.
Removing the replication means i have to set it up again and that means another 3 hours added to an already cram-packed weekend without sleep!
How I can lock out the users to make sure there are no changes to a database other then read_only/restricted_mode/single_user ?
I really don't want to touch that replication...
We have a domain joined SQL 2008 R2 server performing a snapshot database replication to a non-domain joined SQL 2008 R2 server. The snapshot replication is working with one exception. Under one of the tables, there is a Key, Constraint and Index that are part of the database. The Key and Indexes is copying over. However, the constraint is not. Why would the Key and Index copy but not the Constraint?

Each time I try to initialize the snapshot, I get the following errors in the SQL Agent Log
1. Log Step.......cannot be run because the LogReader subsystem failed to load. The job has been suspended.
2. Log Step.......cannot be run because the Snapshot subsystem failed to load. The job has been suspended.
I found posts where the records in the msdb.dbo.syssubsystems pointed to different folders than where the dll and exe files are located. So, I checked that, but they are correct.
The SQL Agent has sysadmin on the SQL Server and is using a windows service account.
I believe it is a security issue because I can run the executables from the command prompt to generate the snapshot for the publication. Have I missed the forest for the trees?
I have two database files, one .mdf and one .ndf. The creator of these files has marked them readonly. I want to "attach" these files to a new database, but cannot do so because they are read-only. I get this message:

I've got two databases on the same server and replicate some tables from one database to another.The replication is configured so not to drop the table if it exists, but to delete the data based on the filter if one exists. There are two tables on the subscriber that have some extra columns.
I get "field size too large" error when trying to replicate them. Is there a workaround without having to make the publisher and the subscriber tables identical by schema?
Is there a script to find which non-clustered indices are replicated? I know i can do this easily through GUI , having a script will make my life much easier ....
