Mirroring Session Drops
Jul 16, 2007
We've implemented mirroring between two identical servers. Sporadically, the mirroring session will drop and the ERRORLOG reflects the errors below at the exact time the mirroring session becomes suspended. We do not manage our back end network since we use a dedicated hosting environment at a remote location. Is this issue solely caused by network connectivity issues, or are there other factors at work?

Database mirroring has been suspended. Resolve the error on the remote server and resume mirroring, or remove mirroring and re-establish the mirror server instance.

I have a Windows NT group that is used to delegate certain database responsibilities to other members of staff and I am trying to grant permissions for the members of the group to be be able to establish database mirroring sessions, as in run the following:
ALTER DATABASE <database>
SET PARTNER = 'tcp://principal_server.domain.com:port';
Although the group has db_owner role membership to the user database which grants the ALTER permission on the database, the following is being generated in the error log when they get to this step on the intended Mirror instance after restoring the database correctly in preperation:
SqlDumpExceptionHandler: Process 59 generated fatal exception c0000005 EXCEPTION_ACCESS_VIOLATION. SQL Server is terminating this process.
* *******************************************************************************
*
* BEGIN STACK DUMP:
* 10/29/15 11:16:15 spid 59
*
*
* Exception Address = 00007FF9A6AF838C Module(sqlmin+000000000003838C)
* Exception Code = c0000005 EXCEPTION_ACCESS_VIOLATION
* Access Violation occurred reading address 00000000000000D8
* Input Buffer 210 bytes -
* alter database <redacted> set partner = '<redacted>';
As you can see, the statement is denied to the user. There are no issues with the database as I am able to run the same query successfully using my own sysadmin account after the failed attempt. What other minimum permissions the group might need to successfully enable them to setup a mirroring session?

The 2.0 version of ASPSTATE is slightly different than the 1.1 version in that one table has one additional column and another table uses a different data type and size for the key. The 2.0 version also has a couple additional stored procedures.
We'd like to manage just one session state database if possible so we're trying to figure out if Microsoft supports using the new schema for 1.1 session state access (it seems to work, but our testing has been very light).
Is there any official support line on this? If not, can anyone comment on whether or not you'd expect it to work and why?
Thanks.

We have a database that we are preparing to set up Merge replication on. We often make schema changes via T-SQL, many of these changes are made to tables on which an ALTER TABLE statement will not do (rather the creation of a temporary table, copying of the data, deleting the original table then renaming the temp table).
My question is how this will affect Merge replication. I have not been able to find anything that is very clear on this. From what I gather, if a table needs to be dropped that is participating in a merge replication, I need to go through the manual process (manual, as in calling the necessary system stored procedures) of removing the the article from any publication (and subsequent filtering), make the modifications, then re-add it to the publication and filtering.
Is this correct? If so, a new snapshot needs to be created, correct? If so, I have a follow-up question regarding that snapshot.
If a new snapshot needs to be created, what happens during replication/synchronization? Meaning, since it is a new snapshot, does the client (subscriber) see the whole thing as new or is it smart enough to recognize that only that one table i have changed needs to be synched?
I am quite new to replication, as you can tell, so please forgive the rambling. I ask these questions because I have heard different answers on both questions...so I would like to get the correct answers.
Greatly appreciated...

Is there a way to have SSIS monitor a folder for file drops? I have been unable to determine which object/task to use for this. We need the ability to have it monitor for files being dumped by other systems, pick those up and then process them. Thanks for your assistance.

I've written an SSIS package which has two DataFlow tasks running simultaneously, importing the data from two separate ASCII files into two staging/prep tables: one Tasks imports records into an ORDER table while the other Task imports the ITEM-level records into an ITEM table.
Starting several days ago, the ITEM DF Task began importing a partial set of records even though the ASCII file clearly showed more records were available.
For example, in today's processing, here is the message from SSIS: << [ITEM Ascii File [1695]] Information: The total number of data rows processed for file "\webserv01globalscapeusr vr logstandarditem.txt" is 217361. >> yet i only found 10,401 rows -- and they all appeared to be the bottom 10,401 rows of the incoming ASCII file.
I cannot see any other untoward messages about SSIS encountering a problem.
There are no Error Output restrictions on the ASCII file.
The ASCII row preceding the 10,401 rows i DID get looks OK.
Can anyone suggest a possible place to look which might explain this "jumping" over the nearly 207,000 rows?
Thanks very much.

XML looks like this:
<?xml version="1.0" standalone="yes" ?>
<hist key="ABC">
<r date="2006/04/21" time="08:53:04" seq="1029">123</r>
<r date="2006/04/21" time="09:21:40" seq="1613">123.25</r>
<r date="2006/04/21" time="09:37:22" seq=" 89">194.21</r>
<r date="2006/04/21" time="09:37:22" seq=" 91">194.21</r>
<r date="2006/04/21" time="09:37:22" seq=" 93">194.22</r>
<r date="2006/04/21" time="09:37:22" seq=" 95">194.22</r>
</hist>
In SSIS it reads all the date, time, seq etc but I lose that super critical "key" in the outputted data flow. If I look at the XSD in visual studio it shows 2 tables related via a "nested heirarchy"... "hist" and "r" with "key" being an attribute in the hist table and all the rest as attributes in the "r" table. However in SSIS it only shows one table so I can't get at that key :(
Any idea how to remedy? I keep messing around with the XSD file but that hasn't gotten me anywhere thus far...
Thanks

I ought to know how to do this, but it escapes me at the moment. I need to write an insert statement for a table that will be based on a complex select query. The select query may return rows that are already in the target table. In that case, I don't want duplicates created, but I don't want the query to error, either. I can't remember how to set that up.

My server (SQL 2005 SP2) typically runs with a procedure cache usage of about 92% or higher... lately it seems like at some point in time during the day it just drops to anywhere between 50% and 65%... with this comes horrible server performance and many snowball effects. If I clear the procedure cache it will go up only about 10% for a minute or two. The only way I can get it to recover completely seems to be restarting the SQL service. Then it will be fine till the next incident. The database is a read only (not set to read only but no updates other than replication). and the same SPs are run over and over and over throughout the day. also did notice that the compiles of the SPs goes up drastically at this point also. not sure if this is part of the cause or part of the effect.
CPU is normal. response from anything (even sp_who) is slow.
i do not understand the way procedure cache works completely so I thought I would ask for some direction.
Any ideas where to look or where to start???
Any thing I can do to catch this when it happens would be great.
thanks a head of time.

Hi all,
I am importing SQL 2000 tables from a developer install of SQL 2000. There are no destination tables to append just new tables being brought in.
I use the All Tasks > Import (DTS) service to do this. I have noticed that the Identity columns do not maintain the Identity attributes. I have to reset them after I import new tables. Is this normal? or is there a bug here?
I checked the MS KB with no success.
Anyone have some info on this?
Thanks.

Does anyone have a good strategy or technique for preventing database drops in SQL Server 2000? I know in 2005 DDL triggers rock, but in 2000 what can you do to audit who drops a database why keeping the same permissions intact.

We are having some unusal problems with an upgrade to SQL Server 2005. I've come across two other people who have had this type of issue but I haven't found a resolution. We are running SQL Server 2000 in production and we have installed SQL Server 2005 on new hardware. We have been working for about a week to verify that all of out existing applications will work properly with SQL 2005.
We have several old VB applications that open a connection to the database and reuse it for days on end. We can test these apps against the production 2000 server and they run fine, when they connect to the 2005 server the connections work fine for 5 - 15 minutes then we get an error trying to execute a command and are told that the connection doesn't exist. (One interesting note, there is only one line of code in the whole program that connects to the database but we have seen 3+ connections from the app when we check in Management Studio for SQL 2005.)
Just to get though the tests we put in some error handling to reconnect if the connection is lost. When we do this the application ends up re-connecting only once, the new connection never has a failure even after hours of testing and we see a 300% performance improvement.
We can reliably cause this problem by stopping the sql server, starting it, waiting a few minutes, then running our app. After one run of the app the problem seems to go away for a while and we can't re-create it nearly as consistantly. Only occasionally will the initial connection fail and every time it does it will be after 5-10 minutes of activity.
Both machines are connected to the same switch and we have ruled out networking issues. We are only seeing this problem with VB6 apps, the VS2005 apps run great. We are looking for the cause of this connection behavior and a fix for it because we don't have the time to fix code in dozens of VB apps because the connections are not stable. Granted the practice of holding a connection open isn't good to begin with but with legacy code you have to work with what you're dealt.
Any thoughts as to why ADO connections from VB6 to SQL 2005 would not be stable?

Please forgive my ignorance, I am by no means a SQL Expert, but have encountered a strange issue.
I have 6 SQL Servers, Primarily SQL 2005 (one older SQL 2000) all loaded on Windows Server 2003 SP1.
We use the servers for a proprietary database that we created which is the backend to a software package we sell.
The issue I have is: We have added a Security account to the servers, and in one case we have granted rights for this account to the TempDB system database. However, whenever we restart this server SQL drops this user account, thus severing connectivity for the app that is relying on that account.
I have set the account as DB-Owner etc, but nothing sems to keep it on re-start.
Any input would be greatly appreciated.

I'm using SQL Server 2012 Bi edition.
I created a model in Visual Studio 2012 and when I process the model, most tables (the ones that should) process 77,546 records and that is reflected in VS.
However, when I deploy the model to the server it is only deploying 76,500 records for those tables.
Where those 1,046 records went to? Is there a setting that limits the records to be deployed? My base tables in the Data Mart have 77,546 records, just as in my Visual Studio model.

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?

I have used DTS in SQL Server 2000 to import an MDB filed (MS ACCESS) of a table. When the table is imported the primary key is lost and the memo field data is completely gone.
I use the tranformation option in the DTS wizard to add the primary key and make sure the data type for the memo field is varchar and has a size of 8000. I need that large size since I am storing lots of html code.
When I preview the data I see the html code that is supposed to get imported. However, when I return all rows from the table in Enterprise Manager the field is empty.
So I tried to manually copy the data from the MS Access Database into SQL Server. Could not figure out if SQL Server has an interface like MS Access to simply copy data into a table. So I linked to the tables from MS Access to the SQL Server table.
When I opened the linked table I see the data in the description field. However, if I return the rows from within SQL Server no data is present.
I have some ASP code trying to read the data in the SQL Server table. However, nothing is returned and when I run the SQL Statement, nothing gets returned. The SQL statement returns all rows. All the other data is present but nothing in the description field.
What am I doing wrong? Any suggestions anyone, please!
TIA

We are using BCP in a Process task. The value for the path to BCP's error log requires double quotes around it. We initially put this value in a configuration file, and that worked fine. Yesterday, we eliminated the config file and tried to use the "Set Values" tab of the SSIS SQL Server Agent job to pass in this value.
The package variable was assigned the value of the path -- all except for the leading double quote. The closing quotation mark was included in the value.
We tried adding a second double quote at the beginning of the value, but that caused the job to fail immediately.
For now we will work around this problem by putting the quotes around the value in a Script task inside the package.
Has anyone else encountered this problem?
Thanks,
Ron

I have few tables, which are replicated and partitioned. They also have archival process. I want to avoid having to run that same process on the subscriber.
Replication of partition switching is easy. However I am not sure how to replicate merge range and empty filegroup/file drops.
There the following article options:
Copy file group associations
Copy table partitioning schemes
Copy index partitioning schemes
I am not sure if these are enough to implement the replication of merge range and empty filegroup/file drops.
I could not find and option to copy partition functions.

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....

Hi all,
I need some solution..
When i execute a program it first deletes all datas from a
'X' table .Then fetches data from various other tables and
inserts into this 'X' table.I finally generate a report from
this 'X' table.
Now the problem is,
USER 1 : Executes the program - Datas in 'X' table got deleted and
filled up with new data.Report is getting processed.....
USER 2 : Executes the same program - Datas in the same 'X' table
getting deleted ..
So the report process of USER 1 got affected.
Solution 1 : Using IP address of local machine i solved the problem.But
i need a concrete solution for this ..something related to sessions..
CAN ANYONE HELP ??
Thanx and Regards

How do you return the ID of an item to a Session in a ASP forum?
I have a MS-SQL Server 2005 database.
My table looks like this QuoteID, QuoteNumber, Date.
In SQL:
INSERT INTO table (QuoteNumber, Date) values ('123490WC1", '06/2/2008')DECLARE @ItemID INTSET @ItemID=IDENT_CURRENT('table')
What I would like to do is return @ItemID to the ASP forum; I assume Session would be the best.
After I get the @ItemID I have a Grid which I will to insert the Quote Items into.
Thanks,
marly

Hi...
I'm developing a web app with VS 2005 Beta and I do not know how to include a seasson variable value into my code.
This is my code:
Function GetData() As System.Data.SqlClient.SqlDataReader
Dim sqlconn As System.Data.SqlClient.SqlConnection
Dim SqlCommand1 As System.Data.SqlClient.SqlCommand
Dim sqlRdr As System.Data.SqlClient.SqlDataReader
sqlconn = New SqlConnection("SERVER=SRVR;UID=USR;Password=PWD;DATABASE=MyDatabase")
sqlconn.Open()
SqlCommand1 = New SqlCommand("MyStrProc", sqlconn)
SqlCommand1.CommandTimeout = 1800
sqlRdr = SqlCommand1.ExecuteReader(CommandBehavior.CloseConnection)
Return sqlRdr
End Function
MyStrProc is:
CREATE PROCEDURE MyStrProc
@MyVar int
AS
IF @MyVar IS NOT NULL
BEGIN
.................
......t12.acct_nbr IN (@MyVar)
.....
END
GO
The variable @MyVar get its value from user log info in login page, and create a session variable.
My Question:
How and where to call seasson variable @MyVar, because now I'm getting this error:
Procedure 'MyStrProc' expects parameter '@MyVar', which was not supplied.
Any help will be great.

This should be easy usually. However, we need to have each row/command executed individually (using the SqlDataSource object in ASP.NET).
