SQL 2012 :: Read Only Database Transfer
Dec 4, 2014
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 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 am trying to do the above using the following...
ALTER SCHEMA [dbo] TRANSFER [schemaame].[tablename];
...but getting the following error...
Msg 15530, Level 16, State 1, Line 5
The object with name "tablename" already exists.
The tablename I see in SSMS is schemaame.Tablename
When I look at the properties of the table, it says the name is 'tablename'.
I cant work out how I can change the schema of the table. Also, surely having a in a schema name is not recommended, right?

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.

we 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?

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?

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?

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:
Server: Msg 3415, Level 16, State 2, Line 1
Database 'TestSprintLD2' is read-only or has read-only files and must be made writable before it can be upgraded.
What command(s) are needed to make these files read_write?
thanks

I have a SSIS package set up that will transfer a file from a location on the network drive and transfer it over FTP to another location.
When I manually run the package, the file is transfer with no errors. But when the job is automated (via Job Activity Monitor) the transfer fails?
I have set the ProtectionLevel of the package to "EncryptSensitiveWithUserKey" and also converted the package to a Development Model. The settings for the FTP is saved within the package.
What am I missing? below is the error message

I am a complete newbie to SSIS. I can create a simple package to transfer data between SQL instances and thats about it.
I have tableA (source data) and tableB (Destination data). TableA has 4 column and tableB has 5. I want to transfer all of the columns from tableA into TableB, but the 5th column in tableB needs to be populated with the ServerInstance name of the server TableA sits on. Do I need to have multiple data sources to achieve this? I have tried but no matter how I set it up, the Column in the destination is set to ignore.

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.

I am trying to transfer all jobs from one instance to another by using data tools. However, once i tried to make smo connection i am getting this error;
A network-related or instance-specific error occurred while establishing a connection to SQL Server.
In order to solve this issue i have tried these solutions;
1. SQL Server should be up and running. (OK)
2. Enable TCP/IP in SQL Server Configuration (OK)
3. Open Port in Windows Firewall (FW ACCEPTS ALL LOCAL PORTS)
4. Enable Remote Connection (CHECK OUT THE sp_configure SETTINGS, i even right-click instance then see from properties )
5. Enable SQL Server Browser Service (sql server browser has been restarted)
6. Create exception of sqlbrowser.exe in Firewall (FW ACCEPTS ALL PROGRAMS)
7. I tried windows and sql authentication which has sysadmin role
8. INSTANCE name is also chekced millions of times

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.

I have an issue when connecting with application Intent=readonly when using Listener name. I can connect to the read only secondary with application Intent=readonly if I use the server name. It gives a host does not exist error when using listener. This happens only if I am using the application Intent keyword. I can connect for normal readwrite operation using listener name.

Considering 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 got this situation where my network admin observerd that there is a high network utilization between 2 nodes in our AG (the primary node & the DR site, 2 separate locations of course); then he advised to compress the data transfer between those 2 nodes as the previous DBA already did that before!
Ok, I have no clue about this, so decided to google it, got nothing. My backup is already compressed through some third party app (just in case if that matters to the subject).

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?

In the full recovery model, if i run a transaction that inserts 10MB of data into a table, then 10 MB of data is moved in the data file. Does this mean then that the log file will grow by exactly 10MB as well?
I understand that all transactions are logged to the log file to enable rollback and point in time recovery, but what is actually physically stored in the log file for this transactions record? Is it the text of the command from the transaction or the actual physical data from that transaction?
I ask because say if I have two drives, one with 5MB/s write speed for the log file and one with 10MB/s write speed for the data file, if I start trying to insert 10 MB of data per second into the table, am I going to be limited to 5MB/s by the log file drive, or is SQL server not going to try and log all 10 MB each second to the log file?

We are in the process of upgrading to a new SQL 2012 server but we have many packages that load data from dbf files created with FoxPro into one of our databases. We have not converted the packages and run them with DTS but we get the following error:

I receive Error: 3967, Severity: 17, State: 1. Insufficient space in tempdb to hold row versions. We have 8 data files for temp db of 10210 GB size and given 10240 GB as max size.
As MS suggest to calculate the temp db file size and growth rate we need to monitor the perform counters Free Space in Tempdb (KB) and Version Store Size (KB) in the Transactions object.
basic formula: [Size of Version Store] = 2 * [Version store data generated per minute] * [Longest running time (minutes) of your transaction
My report disk utilizations says tempdb is full ? I thonk I need a shrink for the file .
Still I am confused in calculating the size , My perform counter gives me data as such
Free Space in tempdb (KB) 279938496
Version Generation rate (KB/s) 53681040
Version Cleanup rate (KB/s) 53422320
Version Store Size (KB) 258720
