We are using 208r2. We used to generate simple reports against to prod. The production is running slow. Just we need the production fresh copy all the time. We are using mainly one database. So I need to have read only copy of that particular database which is sync with the production.
View 3 Replieswe would like something like Mirroring with a Snapshot database so that the "replicated" site can read the database locally.Unfortunately, this requires SQL Enterprise edition on the reading site if I get this right.Is there a cheaper way to achieve this sort of functionality?
View 9 Replies View Relatedi have a database which get refreshed every day from client's data . and we need to pull heavy data from them every day as reports . so only selects happens on that database.
we do daily population of some table in some other databases from this daily refreshed DB.
will read uncommitted or NOLOCK with select queries to retrieve data faster.
there will be no dirty read as there are NO DML operation in that database so for SELECT which happens concurrently on these tables , will NOLOCK work?
I have an inter-company problem.
The one company gathers data into a SQL database hosted within their secure network and now one of the companies (that they are contracted to gather the data for) wants a backup of the data or a replicated database to be able to be placed onto a external HDD or different SQL server on their own network and server.
The catch is that to maintain their data security the original company doesn't want the company that is receiving the data to be able to edit the data. They are concerned that someone might change the data and claim that the data that they gathered is incorrect.
Is there a way to ensure the SQL database remains entirely read only?
I've created an excel spreadsheet with a data connection. This data connection uses a query that runs against a read-only database.
The issue I'm having is that the query never seems to finish running against the database, whether I open the Excel spreadsheet to view the data or run the query in SSMS.
I created the connection on the Data ribbon by going to From Other Sources --> From SQL Server and using the Data Connection Wizard.
Is there some kind of setting or property I'm missing that would allow this query to finish running?
How do I determine the read/write frequency on a database table? I am trying to do this on a 2012 and 2008 R2 servers.
View 2 Replies View RelatedLooking for what others have done to keep a copy of a database, for read only, on another instance. Need to do this once a day early in the morning with no, or minimal, downtime at the source and target. We have applications that access this copy 24/7, so prefer not to disconnect active users, as a detach/attach or backup/restore might do. Permissions are different on each instance, so would prefer not to overlay users on destination database. Options we are looking at right now are...
Log Shipping
Snapshot Replication
Transfer SQL Objects Task (SSIS)
Our environment for this is SQL 2012 on Windows 2012, in the same AD domain located in the same server room. The database size is 1gb. Needs to be copied around 6:30am daily. Does not need to be updated thru the day.
We log ship our production database tansaction logs to a secondary database on a separate remote domain.
Incidentally, this was not set up via the "Ship Transaction Logs" wizard, but instead we had to use the various system stored procedures after restoring a copy of the database on the remote domain in standby mode.
We now have an issue where users are unable to access the remote secondary database without having sysadmin privileges. Clearly we want to avoid this!
We want to be able to use Windows Authentication mode on the server of the secondary database. But since the two domains differ, is it possible to even achieve this?
How can we set up read-only access for users on the secondary database without giving them sysadmin privileges?

What is the best approach for a read only copy of a database that is ~ 1TB. The primary database is fed nightly with an ETL process. We are currently trying to duplicate the ETL to read only server but that process is not going well. So we are looking at other options to let SQL make the copy.
The primary database is on a Win12R2 with SQL 12 or 14, a 2 node A/P failover cluster.
The read only copy will be on a Win12R2 with SQL 12 or 14. It is not a requirement to fail over to the read only copy if the primary should go down.
What would best the approach to accomplish the end result?
Any idea to copy a standby/readonly database. We a have a standby/readonly DB from logshipping for hot standby and we would like to make a copy of this standby/readonly DB into a read/write DB in the same server for daily testing. Thanks in advance!

I have a database called MyData on Production.
I can link the servers using sp_AddLinkedServer.
I want to make a copy of MyData from Production to Testing and rename it from MyData to MyData_Testing.
Currently, I figure I will have to make a backup - copy it from Production to Testing - restore it. Since I can link the servers, I can initiate the backup from Testing - copy - and restore from a script on Testing. The only part I am not sure of is how to copy the file via the script.

Hi,
I set up DB mirror between a primary (SQL1) and a mirror (SQL2); no witness. I have a problem when I issue command:
alter database DBmirrorTest
Set Partner = N'TCP://SQL2.mycom.com:5022';
go
The error message is:
The remote copy of database "DBmirrorTest" has not been rolled forward to a point in time that is encompassed in the local copy of the database log.
I have the steps below prior to the command. (Note that both servers' service accounts use the same domain account. The domain account I login to do db mirror setup is a member of the local admin group.)
1. backup database DBmirrorTest on SQL1
2. backup database log
3. copy db and log backup files to SQL2
4. restore db with norecovery
5. restore log with norecovery
6. create endpoints on both SQL1 and SQL2
CREATE ENDPOINT [Mirroring]
STATE=STARTED
AS TCP (LISTENER_PORT = 5022, LISTENER_IP = ALL)
FOR DATA_MIRRORING (ROLE = PARTNER)
7. enable mirror on mirror server SQL2
:connect SQL2
alter database DBmirrorTest
Set Partner = N'TCP://SQL1.mycom.com:5022';
go
8. Enable mirror on primary server SQL1
:connect SQL1
alter database DBmirrorTest
Set Partner = N'TCP://SQL2.mycom.com:5022';
go
This is where I got the error.
The remote copy of database "DBmirrorTest" has not been rolled forward to a point in time that is encompassed in the local copy

Hello,
if i have a given database (a model) and i want to copy this database in the same database instance. Is it ok to copy the mdf and ldf file and attach the files with a new database name in the same instance.
Or is the datebase name part of the .mdf file?

I have an availability group with read only replicas, readable secondary set to yes and allow all incoming connections. I have also configured the read only routing (at least I'm pretty sure this is correct).
If I login to SSMS with a user in the sysadmin role I can view the objects in the read only replica database. If I login with a user in the public role I'm unable to get past the obvious error:
"The database databaseA is not accessbile. (ObjectExplorer)"
I've also tried adding the "ApplicationIntent=ReadOnly" option.
Unable to access the 'T' database because no online secondary replicas are enabled for read-only access. Check the availability group configuration to verify that at least one secondary replica is configured for read-only access. Wait for an enabled replica to come online, and retry your read-only operation. Changed database context to 'T'.
I have 2 sql servers running in an AG group. SQL 2 is fully syncd and is used for read only reporting.The connection from the listener using ReadOnly works and connects to SQL 2. The problem is, when a database in SQL 2 is suspended from the AG group, the listener does not connect to the SQL 1 (primary).
The AG group is setup exactly like this:
Readable Secondary = Yes for both SQL 1 and 2, Availability Mode = Synchronous
why the listener does not connect to primary server?Connection in primary was set to "Allow read/write connections" for the AG. This meant "Connections where the Application Intent connection property is set to ReadOnly are not allowed. " Setting to "Allow All Connections" worked.
is there a way the data gets updated is through the replication only to subscriber ?
other users should only read the data , they shouldn't do any update at subscriber end.

We have poor performance spikes on a drive containing our log file but this is only for reads and seems to be at a time when we run a re-index job. If this is a likely correlation as to poor performance in reading the log file, and what reads are done from a log file.

View 3 Replies View RelatedConsidering trying to move 2008 acitve/passive cluster with log ship to day old read only 2008 server to 2012 active/passive to 2012 AG Read only server. Only problem is that read only instance may have to be a 2nd instance on a server. The new box is a beast 64 core 256 gig of RAM hp so this is no dog. So I have these choices
migrate 2008 active/passive cluster to 2012 active passive (this will be it's own ordeal)take new monster box and build two instances, one that will run the AG read only database, the other will house reporitng services and analysis services and a few dw databases. We are not heavy into deep dive analysis services yet kind of in it's infancy. Not sure if this other instance will be sql 2008R2 , may be able to do 2012. MY also have a few small sharepoint databases but they barely use it.
I setup an AG with a listener (AO1) on three servers.
Server1 = Primary, Readable Secondary = No
Server2 = Secondary, Readable Secondary = Read-intent only
Server3 = Secondary, Readable Secondary = Read-intent only
Connecting to AO1 with default settings, I end up on Server1.
If I attempt to connect to AO1 with specifying ;ApplicationIntent=ReadOnly (with or without specifying the db name) in SSMS, still lands me on Server1.
Also on topic, in this scenario I would actually want Server1 to be a readable secondary (in the event of a fail-over). So If I did set it as Yes, even If I do get the issue above working, won't I always land on Server1 then?

Why I see absolutely no performance improvement when I spread my primary file group over 8 separate files on 8 separate disks, as opposed to having the primary file group all in one file on one disk.
I have set up 2 identical databases, one spread over 8 disks and one on one disk. Each database has a table called DATA and a column called VALUE. Value is NVARCHAR(200). I have filled each table up in both databases with 20,000 rows.
I then perform a select on each table in each database using CHECKPOINT and DBCC DROPCLEANBUFFERS to ensure I am reading from disk before each query and the execution times are identical in both databases.
I then ran the same queries against each database using a load testing tool and the batch requests per second on each DB is identical under load.
Surely the database with data spread over 8 disks should be FAR faster than the single file database as you have the combined reading power of 8 disks as opposed to 2??
Also, the same is happening for write speeds. When I create the data on both databases, the time it takes is identical on both.
BOL says it should be faster with multiple disks.
Just FYI this is on an Azure virtual machine and each disk is a locally redundant data disk that I have attached to the virtual machine.
Whether write speeds should increase with multiple disks or just read speeds?
What happens when an automatic failover occurs, in a two server AlwaysOn Availability Group configuration, where the secondary replica is configured as read-only?
Will it only allow read-only connections, or will it become read-write and can accept INSERT, UPDATES and DELETES when assigned the new role as Primary?
Is it correct that adding a third server/node, that just acts as passive and should be used for automatic failover, to support true HADR, would NOT need another license .. and that licenses would only be required for the previous Primary and Secondary (Read-Only) replicas?
