SQL Server Session State - Using A 1.1 Database Schema For 2.0 Session State Storage
Aug 3, 2006
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.

I am contemplating storing session state data in a SQL server database (created by running the installSqlState.sql script included in the .NET framework installation) and have established a functioning connection to the database but I am constantly getting "access denied". I've found that tweeking the permission settings in SQL for the ASP.NET user is resolving each specific error that arises but was wondering if there is a more "global" resolution? I'm finding myself having to manually check off each individual object and every option or is this what is needed to resolve the "access denied" error?
Thank you.

I have an ASP.Net (C# 2.0) application that has been using SQL Server 2005 Standard Edition with Service Pack 1 to hold the session state in a testing environment. Currently, the session state is being stored in TempDB, rather than the ASPState database. This has worked very well for us until yesterday. We installed SQL Server 2005 Service Pack 2, as well as the Critical Update for Service Pack 2 (KB933508). Once the SQL server was rebooted, I got the following error message when I tried to access the web application.
The SELECT permission was denied on the object 'ASPStateTempApplications', database 'tempdb', schema 'dbo'.The SELECT permission was denied on the object 'ASPStateTempApplications', database 'tempdb', schema 'dbo'.The INSERT permission was denied on the object 'ASPStateTempApplications', database 'tempdb', schema 'dbo'.
In the web.config file for the application, I have a SQL username and password defined that can access the ASPState database. To correct this issue, I had to give this user db_datareader and db_datawriter access to tempDB.
Has anyone else run across this problem, and is it related to SQL Server 2005 Service Pack 2?

An old website I inherited uses sa to connect to SQL SessionState and had the details in the web.config. This is bad for security.The session state database is of -sstype "t" which is defined as:Temporary. Session state data is stored in the SQL Server tempdb database. Stored procedures for managing session state are installed in the SQL Server ASPState database. Data is not persisted if you restart SQL. This is the default.What kind of WIndows user, SQL Login, role and permissions do I need to create to make Session State secure? (Windows Server 2012 and SQL Server 2012 mixed mode authentication, Webfarm).

I'm currently storing session state in a sql 2000 server for my vs.net 2002 projects. I'm currently developing a new project using vs.net 2005 and was wondering if I could store the session state in the same sql server. Does anyone know if this is possible? If so can someone point me in to an article or code example. All of the examples I have come across are for sqlExpress.
Thanks in advanceJason

I have SQL 2005 mmirroring sucessfully working in an ASP.NET 2.0 web application. I also have session state being maintained in SQL Server using the built-in functionality in ASP.NET. The problem is, even with "allowCustomSqlDatabase=True" and specifying a failover partner in the DSN, it appears that ASP.NET does not work with the failover partner. It always tries to get the session info from the "data source" server specified in the DSN.
Is there a way to get the session state to fail over to the mirrored server without writing a custom session state provider?

Hi,
I need the application not to expire the session always. I need to maintain the session always even if the user keeps the web application idle for long time.

After adding the Witness Server to the Mirror session, the Witness Connection state between the Mirror and Witness Connection is Disconnected and the state between Principal and Witness Connection is Connected.
The procedures defined in Books Online was used to setup Database Mirroring...when the Witness server was added to the Mirror session, only the alter database T-SQL statement was executed on the Principal server.
ALTER DATABASE <db_name> SET WITNESS = 'TCP://<servername>:<port>'
After executing the above statement, a few seconds later the state between Principal and Witness Connection changed to Connected and the state between Mirror and Witness Connection remains Disconnected.
The Mirror session is not using Certificates, every server is on the same domain, using the same domain login account, and all servers have SP2 installed running Enterprise Edition.
Any idea's why the state between Mirror and Witness Connection remains Disconnected?
Thanks,

Is there a way to specify a given Schema as the currently active one for a given database session ? i.e. im looking for somthing like:
Use Schema=<name>
Execute Queries / Stored Procs, etc
.....
I want all the Queries and Stored Procs to execute on the Schema set initially.
I can't use the Default_Schema on the User to do this due to certain restrictions in the way we create users and Schemas.
I know that i can always qualify the objects in the Queries with a Schema Name, but i have a requirement where the Queries need to be generic in nature and need to run on one of many identical schemas in the Database. Is this Possible in Sql Server?
Any help will be greately appreciated.
Thanks

We have mirroring setup for 5 dbs, 4 of which are synchronized and 1 which is in "synchronizing" state on the principal and "restoring" state on the mirror. Mirroring for all dbs has been working fine for the past several months and we have a witness that has allowed automatic failover in the past without problems.
This database has several bulk inserts performed throughout the day and am sure there is some latency due to the size of these transactions.
Not sure as to why this is happening all of a sudden, but the db in question has been in this state for the past 12 hrs. I checked the mirroring status on the principal and it states that it is "synchronizing: data is being transferred from principal to mirror", but the mirror server states that db is in "restoring" state. Can anyone suggest as to how I can get the database on the mirroring server to get back to "mirror, synchronizing/restoring..." state? Or suggest on how I can troubleshoot this?
Thanks in advance.

I have some C# code that iterates through the session state, serializes each object and stores the binary representation in an SQL table with an 'image' column. The problem is: it doesn't work. SQL server doesn't throw an error (at least ADO.NET doesnt propagate it); the table is just left unchanged. The SP works (I tested it with a few simple values); the MemoryStream and byte array are being populated correctly and bound to the parameter correctly.
What am I doing wrong? Anyone have a better approach? I know there is a builtin way of storing state in an SQL server, but I only need to do this once--namely, when a user is redirected from non-secure to secure pages--so I don't want to take that performance hit,
string uid = _session.SessionID;
object toSerialize;
BinaryFormatter formatter = new BinaryFormatter();
MemoryStream stream;
SqlConnection dbConn = SupportClasses.SqlUtilities.DBConn();
SqlCommand cmd;
SqlTransaction storeSession = null;
SqlParameter uidParam, keyParam, objParam;
try
{
dbConn.Open();
storeSession = dbConn.BeginTransaction();
foreach (string key in _session.Keys)
{
toSerialize = _session[ key ];
stream = new MemoryStream();
formatter.Serialize(stream, toSerialize);
cmd = new SqlCommand("store_session_object", dbConn, storeSession);
cmd.CommandType = CommandType.StoredProcedure;
uidParam = new SqlParameter("@uid", SqlDbType.VarChar);
uidParam.Value = uid;
cmd.Parameters.Add(uidParam);
keyParam = new SqlParameter("@object_key", SqlDbType.VarChar);
keyParam.Value = key;
cmd.Parameters.Add(keyParam);
objParam = new SqlParameter("@data", SqlDbType.Image);
objParam.Value = stream.ToArray();
cmd.Parameters.Add(objParam);
cmd.ExecuteNonQuery();
}
}
catch (SqlException ex)
{
SupportClasses.ErrorHandler.HandleSQLError(ex);
storeSession.Rollback();
}
catch (System.Runtime.Serialization.SerializationException exs)
{
// do something
}
finally
{
dbConn.Close();
}
For those interested, here is the code for the SP:
CREATE PROCEDURE store_session_object
@uid varchar(50),
@object_key varchar(25),
@data image
AS
INSERT INTO session_hold (uid, object_key, object)
VALUES (@uid, @object_key, @data)

Hi All,
Great forum y'all have going here.
Just wondering if anyone else has experienced this?
Enterprise Manager:
I have setup and 'sucessfully tested a MAPI session' with a mail profile via support services > sql mail. That works fine, however in sql server agent properties the mail session section on the first general tab appears to be greyed out.
scenario is:
Windows Server 2003 SBS edition
SQL Server 2000 SP3
Exchange Server 2003 is also running on the server, with Outlook 2003 client (so i suspect side chaining issue).
Any help appreciated! did not have any luck googling or using microsoft KB.

I use this code in a utility procedure (for performance testing) but it is really slow.
For example, a session with three events is taking 5 seconds to complete this query:
DECLARE @xml xml=
(
SELECT CAST(xet.target_data AS xml)
FROM sys.dm_xe_session_targets AS xet
JOIN sys.dm_xe_sessions AS xe
ON (xe.address = xet.event_session_address)
WHERE xe.name = @name
);
with data as
(
select
convert(varchar(128),convert(varbinary(128),'0x'+n.value('(action[@name="context_info"]/value/text())[1]','varchar(128)'),1)) context
, n.value('(data[@name="duration"]/value/text())[1]','int')/1000.0 duration
, n.value('(data[@name="cpu_time"]/value/text())[1]','bigint')/1000.0 cpu_time
, n.value('(data[@name="physical_reads"]/value/text())[1]','bigint') physical_reads
[code].....
So, I was wondering (considering the buffer is usually only holding a few hundred events)
1. Is this the wrong way to query data from a ring buffer?
2. Is there any way to make this code quicker?
3. Is it better to target a file store rather than a ring buffer for this?
select geometry::STGeomFromWKB(0x0106000000020000000103000000010000000B0000001000000000000840000000000000003D

I have two extended events sessions running on a server. I do have sql jobs that automatically stop the XE sessions and import the results to working tables. I see two "ALTER EVENT SESSION XXXX ON SERVER STATE = STOP" statements that are being executed for more than 2 days, the wait types are XE_SERVICES_MUTEX and PREEMPTIVE_XE_SESSIONCOMMIT. This is not the first time I see this behavior.I do not want to kill the sessions (I guess the sessions won't die anyway) neither restart the sql service

Hi,
I've my database, testdb, ended up in Suspect state. The SQL log shows " I/O error 38(Reached the end of the file.) detected during read at offset xxxxxxxxxx in file '<path> estdb_Data.MDF'" during recovery. I do not have backup to restore the database from. So to run DBCC CHECKDB, I tried to put the database in emergency(bypass recovery) mode using
update sysdatabases set status = 32768 where name = 'testdb'
DBCC CHECKDB showed some allocation and consistency errors and suggested "repair_allow_data_loss" as minimum repair level.
Now to run
DBCC CHECKDB('testdb', repair_allow_data_loss)
I've to put database in SINGLE USER mode. For that I started SQL server by command
sqlservr.exe -c -m
Now when I try to run DBCC CHECKDB with repair option it says "Attempt to BEGIN TRANSACTION in database 'testdb' failed because database is in BYPASS RECOVERY mode."
So it seems I need to change the status of database such that it will allow me to repair it. If I try to reset the status, the database again goes in Suspect state and it seems DBCC commands don't run on database in Suspect state. Does anybody know how to recover the database in this state? Is there any other way to repair it?
Thanks in advance,
Yojana

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:

* Exception Address = 00007FF9A6AF838C Module(sqlmin+000000000003838C)

* 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?

While attempting to query a Full-Text enabled database where a catalog exists for the database, I receive the following error: "Full-text catalog %database% is in an unusable state. Drop and re-create this full-text catalog." I have dropped and re-created the full-text catalog numerous times with no luck. I have also stopped and restarted the SQL Server service and Full-Text service engines mulitple times with no luck. Other items to note are, we're running SQL 2005 64 bit Enterprise Edition SP1 on a Windows 2003 server. We have an identical setup in development and full-text indexing works without any hitches. I have also checked both the SQL server permissions and the local file-system permissions and they also seem to be more then adequate; in addition, they match the security configurations of our development environment. Lastly, the production database is a restore of the development database.
In short, I'm hoping that someone may have a potential solution other then reinstalling SQL Server...which may end up being the only solution.
Any help or ideas are greatly appreciated!

Hello, I am trying to mirror two databases and i receive the following error to the principal error log. "Error: 1443, Severity: 16, State: 2 ".
I HAVE:
1) SQL server 2005 enterprise SP2
2)ServerA And ServerB in the domain.
3)I have installed both ServerA and ServerB sql server with network system account and the services run both as NT AUTHORITYNETWORK SECURITY.
4) The principal database "Test" is on ServerA, i create a full backup and log backup and restore to ServerB the Full backup and the Log with NORECOVERY.So the database "Test" in ServerB is Restoring......
5)I Have created to both Servers Endpoint to Port 5022 with AUTHORIZATION=NT AUTHORITYNETWORK SECURITY.
6)The endpoint are both operational (I have tested through telnet command)....
7)I have added NT AUTHORITYNETWORK SECURITY user to both Security>logins and i gave full permittions sysadmin to the user.
8)I am executing the query "Alter database [TEST] set partner= N'TCP://xx.xx.xx.xx:5022'";
successfully from ServerB (Mirror) but from ServerA i receive that error!!!!
I believe it's network account security issue, but i cannot find a solution for that..... (I also tried to add DCServerA$ user to logins on ServerB AND DCServerB$ user to logins on ServerA cause previously i recaieved an login security error!!!)
