Multiple Mirroring Configurations.
Mar 18, 2007
Hi all,
as we are looking to a HA-solution for our SQL-environment we're expecially looking for Clustering or Mirroring.
Because we're the central IT-departement for diferent departements in our company we have at this moment seperate SQL-severs for each departement.
The problem is that there is no HA-option configured for none of them.
The mirroring-solution looks the best option for us. But even when we consolidate our bunch of SQL-servers, we end up with 2 machines.
The question is, is it possible to have a single server who can serve as 'mirror' for 2 'principals'?
The idea is to set up a seperate mirror configuration (one witness, one principal and one mirror in each config) for the 2 production servers but where the mirror is serving in both the configurations?
Does anyone have an idea if this is possible, recommendable, supported,... ?
other suggestions are welcome too.
Thanks in advance.

Hi All,
I am working on a project currently where we have many SSIS packages and we want to minimize the number of config files to be used. What I was thinking was using one master config file which will have Server/Database info which will be used by all the packages. Now the thing is there are multiple packages which are being executed from within a master package and I was wondering if this will be an issue. Is there anything else that I will have to keep in mind? Any help is appreciated.
Thanks

Can someone explain what does this mean? This is from http://www.microsoft.com/technet/prodtechnol/sql/2005/dbmirror.mspx
<quote>However, all these techniques for coordinating client redirection with a database mirroring have an important limitation. Database mirroring occurs only at the database level, not the server level. Be careful if your application relies on querying several databases on a server, or uses multi-part object names to query across several databases. When several databases reside on one server, and they are mirrored to a standby server, it is possible that one of several databases might fail over to the standby but the others remain on the original server. In that case, you might need one connection per database that you are querying, so that you do not attempt cross-database queries on a standby server where only one database is a principal and the remaining are mirrors.</quote>
Also I read somewhere that if one mirrored DB fails, all other mirrored DB should also be transferred to the mirror.
For example: Let's say Srv1 (principle) and Srv2 (mirror) and Srv3(witness) are SQL servers with only default instances. The SQL instance has 4 DBs (DB1, DB2, DB3, DB4) and all of them are mirrored to Srv2.
An ASP.NET application has four seperate connection strings like:
objConn1 --> Data Source=Srv1;Failover Partner=Srv2;Initial Catalog=DB1;Integrated Security=True;
objConn1.connect();
objConn2 --> Data Source=Srv1;Failover Partner=Srv2;Initial Catalog=DB2;Integrated Security=True;
objConn2.connect();
objConn3 --> Data Source=Srv1;Failover Partner=Srv2;Initial Catalog=DB3;Integrated Security=True;
objConn3.connect();
objConn4 --> Data Source=Srv1;Failover Partner=Srv2;Initial Catalog=DB4;Integrated Security=True;
objConn4.connect();
If DB2 failsover to Srv2 (mirror), why should all other DBs be failedover?
Thanks

I have to mirror 3 DBs on my sql server instance . I have restored there full backups and log backups on mirror.I have also created endpoints on principal and mirror using default ports 5022 and 5023.
know if i can use the same endpoint for the databases on principal instance ?

I was told that if I wanted to setup mirroring between multiple instance on the same server that each endpoint had to be different number. Is that true? Or can I use the default 5022 for each instance?
Ex.
Server1Instance1
Use endpoint 5022
Server1Instance2
Use endpoint 5022
VS
Server1Instance1
Use endpoint 5022
Server1Instance2
Use endpoint 5023

Server A = primary SQL DBs (mirroring origination)
Server B = failover SQL DBs (mirroring destination)
For database mirroring a witness is required.
Can the witness live in another instance of SQL on server B?

Using SQL Server 2008, we would like propose mirroring between two servers of a critical database. Since we initiate, may require to clarify on its purpose and also required changes from application end.Any changes required from OS Level? (I believe both servers IP or Host name should be added in host entries. Mirroring ports should be allowed/open including Principal and mirror server IP Addresses): Windows Team.Any changes required from Application? (Instance name, authentication: user name and its password should be added in web config files): Application Team.Any changes required from Network Team?Also for mirroring both the principal and mirror servers should be with same version, does it only mean SQL Server 2008 versions are enough or does it also mean to say build numbers 10.00.4000 should also be same.URL....

I need to set up asyncronous data replication across two clustered instances of SQL 2012 across 2 Datacenters. Both the datacenters have a common domain however the vlans are different. There are only 3 small databases on the primary instance.
any issue in setting up mirroring in this case as vlans are different.
Operating system is Windows 2012.

Hello, I had a question I thought someone might be able to answer before I test my theory.
If I run an outer package through SQL Server Agent and specify it to use a configuration file, will the children packages it call also use the configuration file? My instinct is no it will not.
If this is in fact the case, would it be considered best practice to just specify the configuration file for each package through an indirect environment variable? Is it possible to set an environment variable on the set values tab within sql server agent?
Then my only concern is how would developers test packages on their machines, should they also set up the same environment variable on their machine?
Any thoughts?

I have read many posts about configurations. However, in practice, I cannot solve a problem that is bothering me. I have connection managers (that manage SQL Server 2005 connections) configured in a local package. I have ProtectionLevel = 1 (By the way, where do you state that you want it "DontSaveSensitive", etc?). When I deploy the package to another computer (using the deployment utility) though, I get the error "The AcquireConnection method call to the connection manager ... failed". Could someone tell me, very explicitly, how can I use configurations to solve this problem? Or are there other ways to solve the problem? The problem, of course, is that the connection managers' passwords aren't being migrated from a computer o another. Thanks a lot.

Hello, everyone:
How to configure transaction log file size, transactional backup interval and log shipping intereval, exactly? Someone told me it depends on the transaction speed. Is it correct? I have an average transaction speed about 10/min., one day, on SQL 2K/W2K. How should set above issues?
Thanks a lot.

Hi experts,
In SQL Server 2005 database we have partitioned a very big table into 30 partitions each holding few million of records.
Im just curious to know whether there are some configuration related to processors or system hardware in order to benefit from partitioning ? (Ex : If we have multiple processors Whether they need be configured to do a parallel processing ? )
Any real time experience (other than referring links) would be really helpful for me.
Thanks in advance,
Hariarul

I have a question about Package Configurations. I had developed a prototype that has connections defined to 2 DEV SQL Servers and runs fine in DEV. I created a Configuration XML file and changed the XML file settings to point to our 2 TEST SQL Servers. I ran this package without issues. However, I was expecting the 2 SQL Server OLE DB connections within BIDS to point to the TEST Server after the package ran. I still was pointing to DEV. Am I missing something here? Thanks in advance.

Hi,
I have a package configuration for my SSIS packages to allow me to dynamically change the connection string of the connections in my packages. This was done so that when I deploy my packages to my development or test server, the packages would use either the development or test server name in the connection string. I have set the configuration up to use an environment variable to store the location of the config file (an xml config file). The package however does not seem to be using the environment variable though. If I change the location of the config file in the variable's value, it still points to the old location. Can someone please help.
Thanks

Hi,
i keep struggling with dtsconfig.
i have 4 packages which all have the same datasource based on the global-datasource.
is there a way i can save that global-datasource, instead of configuring all 4 packages to use a config-file?

Before I started using package configurations, I made several (wrong) assumptions. My primary use for configurations are to move packages between environments (dev, test, prod), so my config files only contain connection information.
My first assumption was I could create 3 different configuration files (XML) with the connection string properties for each environment. Because I use shared data source connections in my packages, these are the only properties I should have to store within my configuration file. Then I use indirect configurations, which I had a system environment variable set up on each server, called SSISConfigPath. On all servers, I have it pointing to a shared folder on our network so us developers can update the configuration files at will, if needed.
Now, in theory if I deploy all of my packages to the SQL Server MSDB on each of the servers, and schedule a job on each server, everything should work, right? Wrong.
First of all, we had to restart the SQL Agent service in order for the package to recognize there is a new system variable (similar to the Indirect Configuration "gotcha" that Jamie blogged about, but in this case, it wasn't a cmd window, but a windows service).
Next, an SSIS package doesn't first read the configuration file, but it tries to validate the connections that were originally stored in the package to begin with before replacing them. This is a problem when the environment you develop on is your local PC (laptop for example), and deploy to production, the SSIS package tries to connect to your laptop PC first, throwing an error because it cannot find it. If it can find your laptop, it succeeds, and only then switches the connection info with what is in the configuration file.
Can this "validation" step be disabled? It seems changing the "Delay Validation" = true on the package doesn't work for connections.
And when you open BIDs to run a package, the "Syncronize Connection Strings" dialog always appears. When you say OK, it doesn't stick and always asks you each time you open the file.
Please let me know what I should be doing, because this doesn't seem to work as flawlessly as I thought it should.

I have been experimenting with both XML and SQL Server Configurations. Management would really like to go with the SQL Server Configurations, but I seem to be having problems with them.
The main goal is to be able to create a configuration for each connection and have every package refer to its specific configuration, therefore in the future we could change say our SA password and only have to update this in a few places rather than for every package.
In order to experiment with the problem I am having I developed 2 identical packages, except one uses SQL Server Configurations and the other uses XML. The configurations save the exact same properties. With the XML package I can go into the configuration file and change say the password and initial catalogue properties and have these changes go into effect. With the SQL Server package these changes do not seem to take place. So I guess what seems to be happening is with the XML package the connectionstring seems to be generated with the other properties that have been saved in the configuration, but in the SQL Server package none of this seems to take place and the connectionstring just stays exactly as it is saved in the configuration file.
I was wondering if I just seem to be missing something or if anybody else has experienced this problem and found a solution.
Any help is much appreciated,
Sam

Hi,
Within the SSIS package i am currently developing I have a number of variables relating to folder locations. I have added these to a SQL configuration package as i'd like to be able to change these prior to the SSIS package being executed. I plan to launch the package by calling a SQL Agent job from a web page.
On this web page i'd like to be able to change the values in the SQL database so that the package runs with User specified folder locations.
If anyone has done this before i'd appreciate if you could suggest how best to accomplish this. At present i'm thinking of just interogating the created database but as there are no keys etc set up this may not make updating the table easy.
Many thanks,
Grant

I have an SSIS Package that utilizes two Configurations at design time...
1. Environment Variable Configuration sets the root folder variable and subsequently several other variables within the package using expressions (adapted from Jamie Thompson's template package - thanks Jamie)
2. Indirect XML Configuration to set the connection string to the appropriate db.
I've got 3 environments in play.
1. My workstation, using BIDS to design / debug the package. For my PC, the Indirect Config sets the connection to our test server/database.
2. A test server. For the test server, the Indirect Config on the test server sets the connection string to the test database on that server.
3. A production server. For the production server, the Indirect config on the prod server sets the connection string to the prod database on that server.
Problem...
Running the package in BIDS correctly runs against the test db, no problems.
Running the package on the test server in SSMS (either in the Execute Package Utility or using the Agent) without specifying any Configurations on the Configuration tabs, runs fine against the test db.
Running the package on the prod server in SSMS (again, in the Execute Package Utility or using the Agent) without specifying any Configurations on the Configurations tabs runs the package against the test db.
Is this because I'm not specifying the Configuration I have stored on the production server to use the connection string for production?
Curiously, the Indirect Configuration I have setup to read an environment variable to set the root folder (for logging, etc) works fine without having to specify any configurations on the configuration tabs in SSMS. In fact, I don't think you can specify environment variable configurations on these tabs - they open a Browse window to search the filesystem for a config file.
Any clarification anyone can give me regarding these Configuration tabs, indirect configurations, and what their purpose is would be great. I've spent days researching, reading through the two books I have, etc, and there's not much out there on this.
Thanks!

I've been reading up on package configurations, but I'm not quite sure how to use them correctly. If I am developing a package, I want to connect to a testing server. Then, when it is working correctly, I want to connect to a production server. Are configurations a helpful way of doing this, or would it only be helpful if in the future, I need to make the packages reference a different server?

Greetings,I've been looking around all morning and can't seem to find a good answer on this so I thought I'd post a message here.I'm using the recommended practice of keeping the ASPNETDB.MDF data separate from my site data. (I have my site data located in separate databases but still keep them in the App_Data directory.)I'm using SQL Server 2005 Express on a Server 2003 box and I've implemented scheduled backups on the databases in the Sql Server.The questions I'm having are:1. Why isn't the ASPNETDB.MDF database getting attached to the server? Is it using User Instances?2. If it is using User Instance then isn't this degrading performance? If so, how to force it to not use User Instance?3. If User Instance is how it is supposed to work then how are we supposed to do a full backup of the ASPNETDB.MDF database if it isn't attached in the server? (xcopy doesn't seem to work on User Instances because of the dreaded "is being used by another process" error.)Any recommendations, advice, links, or answers to my questions would be greatly appreciated.

Hi all,
I would like to retrive system report that provides the following security configurations for MS SQL
1. Minimum Password Length
2. Initial log-on uses a one time password
3. Password composition (e.g., alpha/numeric characters, not words in
dictionary)
4. Frequency of forced password changes (password expiration/aging)
5. The number of unsuccessful log-on attempts allowed before lockout
6. Ability of users to assign their own passwords
7. Number of passwords that must be used prior to using a password again
(password history)
8. Idle session time-out
9. Logging of unsuccessful login attempts
do i have to script it or is there any alternate option
thanx in advance

We have been given a new Database server with SAN drives attached for storage. We will see the SAN as 4 separate drives on the server (D,E,F,G). Drives D and E will be a 7 disk array using RAID 5. F and G will be s sperate 7 disk array using RAID 5 also.how best to configure our databases on these drives. I was thinking of splitting the systems db's, user db's, indexes and logs like this:
D: System DBs
E: User DBs
F: Indexes
G: Logs
I wanted to keep data and indexes seperate as well as data and logs seperate. I'm not sure if it makes sense to keep the system dbs on there own filegroup or not.

I want to see if anyone in this community has come across this and has found a solution.
we have 3 different SQL Servers because we are still porting over SQL 2k databases 2k5. We have multiple databases of course. We would like to create some kind of template that would create the connection manager based off of the information in our XML configuration file. We are thinking we would have 2 files for this. One would house the actual server information but omit the database name and username/password. The second will be a list of all the databases with their usernames/passwords for each one.
If we put all of these in the configuration files and do not have a connection for each one, SSIS will throw the error stating it is missing connection managers for those items. We would like to see about maybe specifying the database name and have the connection manager dynamically pull the database specific information into the package. This would also need to be able to handle more then 1 database should there be the need.
I am new to SSIS. It seems pretty nice and extensible but my learning curve on it is horrible as I never programmed DTS packages before.
I hope I am making sense here. Thanks for any help offered!

Hi all,
I have just set up my first deployment utility for the Integration services package i've been building. I seem to be getting problems with the package Configurations. I added an XML config file so that i could change the values of my SQL connection manager at deployment time. This was so that i could deploy it on both a test environment and the live environment. Any other variables can be changed in code by the calling application. As soon as i added the options for the sql connection manager and enabled package configuration i got errors when running the application:
[Execute SQL Task] Error: Failed to acquire connection "InternalProductionData Connection Manager". Connection may not be configured correctly or you may not have the right permissions on this connection.
This is before i even deploy the project. If i disable the package configurations everything works as expected. Can anyone help suggest why this might not be working.
Many thanks in advance.

I'm relatively new to SSIS, but I have read all the info/threads on Package Config. and I'm really confused.
Our production env. is clustered, and we are running multiple sql instances, so the sys admin does not want me to use Env. Variables or XML files for the package configurations (it's too hard for him to maintain the info across multiple instances, etc). So, I am storing the package configurations in SQL.
Just as a simple test, I used the wizard to create the 1 package configuration for production. The configured value as a complete connection string
When I run the package, it completely ignores the package configuration. How do I change the connections on my tasks to read from the package configuration instead of the connection manager they are currently associated with?
TIA,
Mary Jo

Hey there,
I know that many articles have been written describing configurations for packages but I have yet to have found one that describes if it is possible to use SQL Server configuration type for a package that is to be tested on DEV, then UAT, then PROD boxes.
I would like to know if there's a way to store values in a config table in a database on DEV, UAT and PROD but never have to change anything in the package.
I mean, I wonder if I can pass a parameter that defines the server to go get the configurations from.
The 3 servers will contain a database with a config table named the same on each server but have different configuration values to point them to the proper sources and destinations depending on which server the configuration database resides.
Thank you,
Robin

Hello,
I have a solution with a lot of packages, and each of them has configurations set on an SQL Server table. Right now the information in the table is outdated and I'd like to overwrite it with the new values on the properties of each package (and its elements). Is there another (faster) way to do this without having to disable/enable or recreate all configurations manually?
Thanks in advance
