SQL 2012 :: How To Sync DB Between 2 Servers
Apr 23, 2014
I have 2 server PROD n DR server all the PROD server DB is synched to DR server through log shipping. Now to chk whether the DR server is working or not in case of any disaster we shut down the PROD server now all the app request is handled by DR server,it is working fine. For 1 week we work in DR server now its time to move back to PROD server so that all the 1 week data in DR server should be replicate back to PROD server. Log shipping is deleted once the DR Server is up. What r the options other than Backup? It is SQL 2012

I have two db instances on different SQL Servers. One is my test db and the other the prod. db. Each has two tables that hold lookUp values for the entire application. I would like to keep these tables in sync. in both dbs. The prod. db would be the master. I was trying to design a trigger to insert, update, or delete the appropriate records in the test db as they were added or deleted from the prod db.
I'm getting too many prefixes errors on the script when trying to reference the table on the test db using four part naming convention.
Any ideas on how to resolve this issue? Do I need to set up a linked server to accomplish this functionality? If so, how do I setup security for a linked server?
Thanks in advance.

Ok..here is my problem. I have two SQL servers that I need to haveidentical, at least semi-real time data on. One is in a public DMZwith full access to and from the internet, and one is behind acorporate firewall and the box can get out to the internet but cannotbe hit directly from the internet in. The two are on seperatenetworks and cannot be connected via lan. Is there a way for me tohave semi-real time data transfers between the two to keep bothservers identical? I have thought that the server behind the firewallcould initiate an XML session with my dmz sql server and processupdates, but I am unfamiliar with how it would know what has changedon the remote server and how the remote server would know what haschanged on the server behind the corporate firewall. Any good ideas?ThanksDan Hirsch

Last night we had a problem caused by a stored proc being deployed to only one server rather than two. I want a way to ensure that we can automatically run on a schedule a check to ensure that the 2 procs on 2 servers are the same.
I need a less robust solution that I implement tomorrow that doesn't involve buying third party tools and a more robust long term strategy that could if need make use of third party tools.

I've stepped into a new environment and have never dealt with multiple data files on user databases only with Temp db.What would be the best way to get all my data files in sync. I have done this on databases that aren't that big in size or off in size by a lot. Here is what I have
Mdf -- 69 GB
ndf -- 3
ndf -- 3
ndf -- 3
ndf -- 3
ndf -- 4

After failing over to the DR replica. All databases are out of sync. DR replicas were setup as async the other 2 are set up as sync. Is this by design. No data has been updated to any of these as they are test dbs. So all dbs should be the same, no data loss.

I would like to know if it is possible to split a database across different servers, in the same manner you can split it over multiple drives on the same server We are trying to balance the load cause we are finding that the current server can't handle the load

I have multiple instances of SQL 2012 Std Edition on a 40 physical core server.What I have done is the use the Process - SQLServr -% Processor time Stat and divided by 16 ( the max number of Cores Std ed. can use) as a instance level measure. I also use processor object stats to show how busy the server is. How to represent the servers CPU utilization?

I have installed SQL Server on Server A. I have installed Integration Services on Server B.I found that you need to addto the integrations services MsDtsSrvr.ini.xml file the server for the database if you want to use MSDB package store. The issue I have now is how do I execute the jobs on the Integration Server. I dont want them to execute on the SQL Server. Is there a way to configure the SQL Server Agent jobs to execute the package on the other server? Do you have to setup windows scheduled tasks or some other tool to execute command line packages on the IS server?
I'm looking for any info on segregating these roles but still using the MSDB store for pacakages. I don't want SQL server installed on the IS server or IS on the SQL Server. I want the Integration Services server to do all processing... not database level obviously but flat file reads, web service calls, data manipulaiton, custom code, etc and just pass the input/output of data to the SQL server for storage or retrieval to offload the workload and segregreate responsibilities.

Scenerio : To keep a very large system running optimally in a VM cluster, Take PR01 and make PR02, PR03, PR04. Distribute the 45 databases and 9T+ of disk across multiple VM guest.
Each PR## is a SQL Server 2012 Enterprise guest on a VM 5.1 cluster.
So instead of PR01 needed 16 core and 128g of memory, each one will have 4 core and 32g of memory. Making VM HA more manageable. (yes, DRS rules will apply). Also provides more HBA paths and distributes i/o over more physical disk on the SAN.
Instead of a connection string having to know PR01.dbo.UserDB01, PR02.dbo.UserDB03, ect the connection would be PRDB.dbo.UserDB01. That way if needed 1) UserDB can be moved to any of the PR## 2) new PR05, PR06 can be added as needed. The end user and processes are not allowed to touch system databases, no PR## will have a user DB called the same name.
There are seperate VM guests on other VM clusters and Citrix servers that need access to PRDB. As things expand and move around, none of the connection strings need to be changed.
I am looking into RadWare and modifing level 7 information, but that is iffy and $$$$$$.

I've just restored a DB from one server to another. Part of the DB is an assembly used in a Function that unencrypts some data held in a Varbinary(Max) column.
When I execute it on the original server it works fine across all rows of the table, when I execute it against the new server it fails because it's seeing dates in MM/DD/YYYY format, it works if the day of the month is less than 13, but obviously the date would be wrong!
Setting the DATEFORMAT to MDY prior to executing the function has no effect either.
It's the same DLL in the same location, the SQL Server settings as returned by DBCC USEROPTIONS() are identical.
The SQL Server editions and Window OS are the same

Server: SQL Server 2012 Enterprise 64bit
I created a maintenance plan with full user database backups, backup files cleanup, and database shrink.
I did it in SSMS and it also created "Reporting Task for subplan-{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}".
It works fine in the development server where I created the plan. I imported the same into other environments test, stage, and prod. I did use BIDS to change the connection string manual "Local server connection". The job runs fine in other environments but it fails at the end where the "Reporting Task for subplan" is executed. I looked at the dtsx file codes and I could not find anything wrong.
It seems to be a bug at the Microsoft side.

So I have 2 servers S1 & S2.
Database Group 1 = L1 with Primary S1 and Secondary S2
Database Group 2 = L2 with Primary S2 and Secondary S1
For 99% of the time the 2 groups of databases are not related. For the 1 procedure that does move data from L1 to L2 something like
Update L2.DB.Owner.Table
set flag = 1
Whare a = 0
On S1 I have a linkedServer with connection to L2.
If I have a failover I cannot have L2 on S2 as they are essentially the same server.
How to I use the 2 groups hand in hand.

Curious what the industry standard is combining multiple instances on single server ?
Right now i have separate servers for OLTP, SSAS, and SSIS, and for OTP have Development, Test, and production environments. Im considering combining the SSIS and SSAS services into additional instances on each environment servers.
Now (Production)
OLTP
SSAS
SSIS
After
1 Server with 3 separate instances for SSAS, SSIS, OLTP. Then replicate this model through the environments to utilize development and testing.

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?

I have a HA Listener which is visible and can be connected to, it has a read only secondary on a different subnet so when connecting to it we use the applicationintent = readonly and multisubnetfailover = true.
Trying to connect it as a linked server is giving me problems. I tried putting the extra info into the provider string but keep getting the failure to initialise error. I am trying to link SQL2012 to a 2012 HA group but will also need to connect from a sql2008 server as well

I know now that AlwaysOn feature HAS to be installed/configured on a Windows Clustering environment, BUT the secondary replicas, like the Disaster recovery replica residing in a different Data Center HAS to be also in a Windows Clustering environment or can it reside on a SINGLE SQL Server INSTANCE?.

I have a group of about 5 servers (which will likely grow toabout 25 in the near future) with their names listed in a table in a database on one of the servers. I want to query all servers in that table using the following query to pull the storage drive, database name, created date, age and size of the databases for each server listed in the table:
SELECT left(mf.Physical_Name,2) AS Storage_Drive,
DB_NAME(mf.database_id) AS DatabaseName,
db.create_Date,
DateDiff(day, db.create_date, getDate()) Age,
sum((mf.size*8))/1024 SizeMB
[Code] ...
How would I best accomplish this if I want to implement it using a TSQL procedure?

I have a report that was designed using SQL Reporting Services that sits on a SQL reporting server. It's nothing too exciting, it is essentially a three page application with legal jumbo on pages 2 and 3 and applicant data in fields on page 1.
We use rectangles to force page breaks to page 2 and to page 3.
When running the report on the report server, it shows and prints fine.
When running the report from the QA website internally, it shows and prints just fine.
When running the report from the production website from a machine internally, it shows and prints just fine.
When running the report from outside of the company network, the report is jacked. It obliterates large chunks of text, crams text together, and creates blank pages.
I need help in determining where I even begin with trouble shooting this!

can anyone tell me if they know of a way to automate the update process from development servers to live server, with little interference from an administrator
I have a development team that are constantly updating their databases along with their ASP code, and want to publish changes an a weekly basis. They have asked me for a way to take their new structures, tables, procedures etc, and copy them to the live servers, but NOT to interfere with existing customer data.
Funny I know – and I hate the idea btw :(
Any references, contacts, 3rd party tool recommendations welcome,
Thanx,

I am in the middle of a major migraton project, moving from x86 SQL 2000 to IA64 SQL 2005. I have a business need to link to several legacy servers. I have a number of problems I am trying to solve.
1) Linking a Kerberos server to a non-Kerberos server.
2) Linking x64 or IA64 servers to x86 servers.
3) Linking SQL 2005 to SQL 2000.
Two of the errors I am encountering are:
------------------------------
TCP Provider: An existing connection was forcibly closed by the remote host.
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
OLE DB provider "SQLNCLI" for linked server "SCDC250DB" returned message "Communication link failure".
(Microsoft SQL Server, Error: 10054)
------------------------------
And
------------------------------
The OLE DB provider "SQLNCLI" for the linked server "SCDC250DB" reported an error. Authentication failed.
Cannot initialize the data source object of OLE DB provider "SQLNCLI" for linked server "SCDC250DB".
OLE DB provider "SQLCLI" for linked server "SCDC250DB" returned message "Invalid authorization specification".
(Microsoft SQL Server, Error: 7399)
If someone has worked through these problems before, I would appreciate it if you could direct me to the relevant documentation to resolve these issues.
Thanks!

Hi Forum, Ive been unsuccessfully trying to copy data from one table to another, very simple scenerio!
Table1 ID(PK), FirstName, Mobile, Date.
Table2 FirstName, Mobile.
The first question I have is should I fill Table2 at the insert stage OR should/do I update Table2 from Table1 as the users details are entered. ie create some kind of relationship.
Really appreciate good advice! cheers P

I have a SQL 7 backup file that I restored onto a new server. All the objects within the database are not owned by dbo, instead they are owned by a db user. When I tried to login to the db it said that it wasn't a valid user. So I added the login to the system. Now when I login it says it is not a valid db user. I have attempted to sync the id's but don't know how. In 6.5 I could run an ad-hoc query to match the SUID's for the system and the database. In 7.0 I can not because the suid for the db is computed. Any ideas on how to sync the user ID's so that I can login to the server using the target db as my default and can query the table with prefacing the owner(I can get in if I give my login SA privelages but then I have to preface all the objects with the owners name)?
Thanks in advance for any help that you can offer.

hi,
we currently have a web server/db on-site and a similar backup machine across the country. we're using a pretty bad backup strategy. we zip up a backup file, thats done on the main server every night, then ftp over to the back up server then run a restore.
lately ive been having problems with the main server. i would like to have the machines sync'd up as close as possible.
ive searched the threads and noticed replication and log shipping to be the most practical, but im assuming most of the machines are on the same domain.
what would be my best bet for machines connected over the internet, no vpn?
also the db on the main machine get queried/inserts all day from 7am - 6:30pm
thoughts?
thx
