How do I test failover to point to the mirrored database instead of the principal without having to stop the primary instance? I would like to just bring the mirrored database on the primary instance to an offline status and see that the same database on the mirrored instance getting activated as the primary. This does not happen if I try to put the database on the primary server "offline" as it complains that any database that is being mirrored cannot be taken offline.
We need to start testing our Microsoft cluster servers. Has anyone heard of any plan or products one can use to test the failovers? Please advise Thanks Susan
1. Once fail over to secondary replica, what will happen to connected session in primary node? can the session fail over to secondary seamlessly or need to re-login. what happen committed transactions which has not write to disk. 2. Assume I have always on cluster with three nodes, if primary fails, how second node make write/ read mode. 3. after fail over done to 2nd secondary node what mode in production(readonly or read write). 4. how to rollback to production primary ,will change data in secondary will get updated in primary.
We have set up Mirroring with a witness server and everything works fine when we failover from the SQL Management console.
However, if we failover when our Maccola client is connected, the client blows up - clearly because it can no longer connect to the database.
The ODBC DSN used by the Maccola client shows a checkbox for the 'select a failover server' but the checkbox is grayed out.
Also the summary of settings for the DSN at the end of the wizard reveals that the failover to server (y/N) option is set to N.
The default setting for this DSN is 'populate the remaining values by querying the server' but it doesn't appear to be getting the settings for failover from the server or any other interactive DSN settings either. The server is clearly set for mirroring.
Another suspicious item is that the DSN cannot connect to the server with SA permissions, even though the server is set to mixed security and we use the correct authentication.
Is it possible that the client MACHINE is not authenticating with the domain or sql server properly. We are logged into the client with the domain account that is the SQL admin account on the sql server box.
We should be able to interact with the sql server settings through the ODBC DSN on the client shoulnd't we?

I am using SqlServer 2005 Express Edition. I have written a stored procedure that has a transaction to make sure that it rolls back in case of failure. Is there a way to test that the transaction works. I don't now how to cause an error that would cause the transaction to roll back and raise the error with the details of the exception. Thanks, laura
hello everyone i was hoping to get some help. i have sql server2000 and iis5.1 running and im using vbscript through asp. i have a table that has two keys so that together they make a unique key. so i am trying to test my table in asp so that if there is a duplicate unique key inserted then show an error... Can anyone help me?
I want to run remote procs from a local - central proc, but don't want to crash my proc if the remote NT Server or SQL Server is not available. So, I want to test for NT and SQL availability first.
/* I find the server-dbasename name in a lookup table, and then build dynamic script */ SELECT @DBName = "<SRVRNAME~DBASENAME>" SELECT @QueryString = N'master..xp_cmdshell "ECHO >' + SUBSTRING(@DBName, 1,6) + 'pipesqlquery", no_output' EXEC @Results = sp_executesql @QueryString
SELECT @Results /* <-- testing here.... */
=====================
If the NT / SQL is running, "@Results" should = 0 (success on the ECHO to the PIPE) If the NT / SQL is NOT running, "@Results" should = 1 (error on the ECHO to the PIPE)
If I test in QA, I get the expected "@Results" values.
If I run the proc, I get "@Results" = 0 for both events, and them my proc fails on the remote proc call if the NT / SQL is NOT running.
I don't know how to write DMO in TSQL to try that. I have also tried using 'odbcping' too.
HINTS? Better way to test remote NT / SQL is NOT running?
i have performed all the steps for the replication there are two problems i encounytring (i) how to check whether the replication is working or not (ii) can replication on the subscribing server automatically create the table which publishing server is publshing (iii)please tell me someother forums for sql server
what my knowledge says that in replication if i modify the data at one place it should automatically be modified in the subscribing server but this thing is also not happening (its not flashing any error message as such) please tell me what all things i need to do to make sure that everything starts working

Has anyone ever heard of using Response.Write to test sql queries in the query designer? Here is the actual suggestion I was given recently:
Response.write your sql query. Copy the query to your db query tool and run the query. Adjust the query as necessary to return the recordset you desire. When you have the proper query, adjust your asp code.
The query editor/designer doesn't like certain symbols and extraneous code. So how exactly can you use Response.Write with a sql query without getting errors in designer?
I've begun some testing with the June beta of SQL 2005. One problemI've hit is with scalar-valued functions. The error I often get whenexecuting functions is "Select statements included within a functioncannot return data to a client.". These same functions are workingfine under SQL 2000.Has anybody seen this behavior or know what the deal is?
I've started researching on Unit Testing and I must admitI had never heard of Unit Testing until a couple of monthsago. Obviously I am interested in Unit Testing StoredProcedures.I read the TSQLUnit documentation (not all of it) and i also raninto a newsgroup post saying TSQLUnit is very small comparedto NUnit. The conclusion I am making out of this post is thatI should rather spend time resarching/reading about NUnit thanTSQLUnit. Is that a good assessment?I would like to you what you use and if you use actuallyUnit Testing or some other method? I ran into White Box/Black BoxQA testing. All these are new to me. Any good place to read about"Extreme Programming"? I ran into one link that I saved it at work.That's one place i will read more.Any links, documentation or books you would suggest?I searched Amazon and I didn't find anything interestingregarding SQL Server and Stored Procedures.Thank you
I am running windows xp pro on my home computer and would like to test andatabase driven ASP .NET web application. I need to be able to create an SQLdatabase which will be assessed by the web application. I already have alocal IIS Server up and running.At work, I use SQL Enterprise Manager. I wanted to download it on my homecomputer but cannot find it anywhere on the net.How can I test my web applications at home on a person computer?Thanks.Jess
Hi,How do I write a query where if a column, "value," is NULL I returnthe phrase "No value entered" but otherwise return the column's value,even if it is the empty string? I'm tried to modify this simple querySELECT value FROM meta_dataThanks, - Dave
can any one guide me how should i do performance testing on database size for sql server. I dont know how to read the execution plan, though i have read many document but still i am not clear. For are the reports which shows the performance has been down and its all accurate.
Is it possible to get a list of all the fixes and enhancements that are going into SP1 for SSIS? This will make it alot easier to test seeing as we will know what we are looking for.
At the moment, the only way (that I know of) to test a subscription seems to be to schedule it a few minutes ahead in time and wait for it to happen. Dies nayone know if there are plans for and "Execute" or "tTst" button? It would be nice to have one.
i've been informed that one way to test a query is to execute and roll-back it back as a transaction. my question is the following: using the aforementioned mechanism, how can i examine the database state before the query is rolled-back?
How does one determine in a VS load test the exact limit of the number of users the report server can handle without failing?
If 200 users proces request reports simultaneously, what is the best configuration for a single box deployment. The reports are parametrized reports and do not run from cache.
Hi I’ve got a simple SQLdataSource which is wired up to a gridView. When the page loads, it’s sometimes likely the data source would contain no data – how can I test for that in the code behind (no data)? I’d like to only show a button if there is data? I’m using ASP.NET 2.0 with C# Many thanksRichard
Hi I really need your help. I’ve got a table with 4 columns – username (a string of text), dateTime (a date and time), duration (time in minutes), roomID (URL). I really need some help with writing up some code behind to check if a user has permission to continue. I’ve got the first bit, but I need help with collecting the data and testing it: SqlConnection conn = new SqlConnection(Global.ConnectionString); SqlCommand cmd = new SqlCommand("select * from tblActiveSession where Username=@Username", conn); SqlParameter paraUsername = cmd.Parameters.Add("@Username", SqlDbType.NVarChar); paraUsername.Value = this.txtUsername.Text; try { conn.Open() This is where I need the help. What I need is to test each row against the following: If now() is within the allowed time frame – greater than dateTime, but less than dateTime + duration, then break the loop and redirect to roomID. I really hope this makes sence, and I’m greatful for any help. Many thanksRichard
I am creating a View in SQL2000 where i concatenate values from multiple tables. My problem is that if one of the values is null then the whole string is null, so I would like to know how to test for nulls within the Select part if the View.
Can someone advise me as to the best way to loop through a collection of columns for each row in a table testing the value of each column for nulls etc and then entering the column name into another column where the condition is true..
We are looking for a software program that will allow us to test our SQL server. We are looking for the most thorough tool that is available. I was asked to post a message, so I do not have too many details.
I currently have Apache, MySQL and php running on my local machine to enable me to test php code on localhost
I've been asked by a colleague if I'll work on an SQL 2000 database they're having trouble with. They said they will provide Visual.net, SQL 2000 and any other software I need.
I'm completely in the dark on this, but have some starting questions:
To test my code, will I need to set up a sever on localhost?
Will I need other software than Visual.net and SQL 2000? I'm using DW MX for my web stuff.
Whre can I find a basic introduction to ASP / SQL 2000 in the form of a tutorial?
How fast does this combination run? The database has 25,000 rows and 6 columns. What would be a reasonal expect time for a result?
