Hi!
Is it possible to use teamed network adapters for Principal and Mirror in a quorum?
I need to use a VLAN networkconnection in order to setup a Synchronized Database Mirror with Witness session.
Thanks in advance!
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 a Server Agent Job that does a full backup of my principal database. I then have a separate job which does an incremental backup of the log files every 20 mins throughout the working day - the incremental backup sends me an email if it fails.
If I establish a failover to the mirror server, the backups continually try to run, sending me an email every 20 mins telling me that it can't back up the database as it's a Mirror.
Is there any way to script a method in the job that checks to see if the DB is a principal or mirror. if it's a principal I want the backup to happen, if it's a mirror I want it to skip the job.
Thanks in advance to anyone that can help

Hi guys, right now I am facing this scenario several times and I wonder why it can be happen. Both SQL servers are in Enterprise SP1 edition. The mirroring setup can be work fine to me. Once my principal get attacking by DDOS, then mirroring session change the status to 'DISCONNECTED'. However, after DDOS attack solved and line connection gets back on the principal server, the mirroring session still remain to the status ('DISCONNECTED'). If I restart the SQL services on principal server or mirror server, then only the mirroring session change to 'SYNCHRONIZING' status. Does anyone faced this happen before? I need some assistance on it and hope able to get any explanation or solution from you guys. Thanx and have a nice day.
Best Regards,

Hi,
can we control how transaction send from principal to mirror ?
If application inserting 10000000 rows in one transaction to principal database
how infomation will be transfered once it is commited and where it will be stored before it is replayed on mirror database?
1. Is it going to be 1 big data packet ?
2.is it going to be split on many packets (of what size ?)
Thanks

Hi there.
Imagine this scenario in High Availability mode :
The principal sends a transaction log to the mirror, then the mirror saves the log on disk and then notify the principal. What happen if the acknowledge is lost, because a network failure(back on track in 1 or 2 seconds) and the principal dont receive it ?
In this case an automatic failover will not occurr, and i dont really know what happen next...
Will the mirror resend the ack ?
The heartbeat mechanism plays an important role in solving this scenario ?
The principal must receive the ack to commit the transaction, and i´m not seeing how the problem is solved.
I have one other question. In "Database Mirroring in SQL Server 2005" document, is said that "...unlike a distributed transaction, failures to commit on the mirror will not cause a transaction rollback on the principal".
But in this case the mirror will be inconsistent with the principal. How is this problem solved ?
Thanks in advance.
In documentation about SQL mirroring, the only thing about version requirement are that: 1) enterprise, standard, developer edition; 2) SP1 for official support
Is there any requirement for the Principal and Mirror SQL instances? For example, can one be Enterprise, the other one be Standard? Can one be SP1 and the other one be SP2?
It seems we are having some problem with the above scenario, not sure if that's supported..
Thanks!
We were having problems setting up the mirroring, so I did it via command lines. I found out the "alter...set partnership" command works on the mirror server going to the principal, but gets a 1418 error when going from the principal to the mirror.
So if A is the principal and B is the mirror, A to B fails but B to A works.
If I reverse it so that B is the principal and A is the mirror, B to A fails and A to B works.
Any suggestions?
I have checked my Production databases, both are went to Disconnected state, both are unable to connect to the application, i checked all the services and its working fine. and restarted the end points on Principal and Mirror, still issue not solved, after restart the witness server End point both the databases are working fine.

The principle, partner and witnesss have two NICs each (NIC1 and NIC2). I want them to communicate in NIC2 for sending logs and establishing quorum. This will happen in their own private network (say 192.168.1.0/24). The NIC1 in each server will be available for client communication. The domain and clients are in the network (say 10.1.1.0/24).
I am using the same domain account as SQL server service account in all three servers.
How can I do this?
Thanks
We've had two instances now where when there is a network connection timeout to the mirror from the primary, the primary db server goes to 100% utilization and refuses all connections.
The first time we had to reboot the primary, the 2nd time mirroring picked up again 10 minutes later.
There are two dbs being mirrored, one is 15gig, the other 4gig. Both boxes are running SQL2005 64 bit and Win 2003 64bit.
This happened at 6am and typically there shouldn't be a lot of traffic at that time but here are the error messages in the SQL log below.
We are going to try and move db communications to a separate network and network card - but this looks like either a bug in mirroring or a configuration problem on our end - though it works just fine other times.
Any thoughts/suggestions would be greatly appreciated.
Thanks!

Ive read a few docs and i have some doubts about the implementation i ll make.
I will setup a FCI between ServerA and ServerB. So my databases will be running on server A or on ServerB. they will be replicated using AllwaysON to ServerC.
Because ill use a diferent vlan for AllwaysON replication iam having some doubts on how can i set the endpoints...
For example.
I ll have the following ips configured for AllwaysON replication on Server A, Server B and Server C 10.10.240.1/10.10.240.2/10.10.240.3
Database teste will be running on serverA. the endpoint configured will be 10.10.240.1 but when database fails over to Server B (using FCI) the ip configured there will be 10.10.240.2... so AO replication will stop working.
I tough on associating a virtual ip to the AllwaysON cluster resource but Microsoft doesn't recommend to alter AllwaysON cluster resource.
How can i implement this configuration?

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,
I was trying to test mirroring and now would like to delete the mirror database but it says I need to remove database mirroring first. I deleted the endpoint and cannot figure out how to remove the mirroring. Can someone please help.

Can any one tell me the difference between Select Query and
SelectCommand in data adapters?
Using SelectCommand:
string selectSQL = "SELECT CustomerID, CompanyName FROM Customers WHERE Country = @Country AND City = @City"; SqlConnection nwindConn = new SqlConnection("Data Source=localhost;Integrated Security=SSPI;Initial Catalog=northwind");SqlDataAdapter custDA = new SqlDataAdapter(); SqlCommand selectCMD = new SqlCommand(selectSQL, nwindConn);custDA.SelectCommand = selectCMD; // Add parameters and set values.selectCMD.Parameters.Add("@Country", SqlDbType.NVarChar, 15).Value = "UK";selectCMD.Parameters.Add("@City", SqlDbType.NVarChar, 15).Value = "London"; DataSet custDS = new DataSet();custDA.Fill(custDS, "Customers"); Using Select Query:
SqlDataAdapter
da = new SqlDataAdapter("select P_UID,P_EMIAL,P_NAME from p_users where p_email=@p_email
and p_pwd=@p_pwd", con);
da.SelectCommand.Parameters.Add("@p_email", SqlDbType.VarChar, 50).Value
= etxt1.Text;
da.SelectCommand.Parameters.Add("@p_pwd", SqlDbType.VarChar, 50).Value = pwdtex.Text; Can you plz tell vat is the need for giving custDA.SelectCommand and adding parameters to that command instead of directly giving Select Query in Data Adapter? Similarly Update Command: custDA.UpdateCommand.Parameters.Add("@CustomerID", SqlDbType.NChar, 5, "CustomerID") custDA.UpdateCommand.Parameters.Add("@CompanyName", SqlDbType.NVarChar, 40, "CompanyName")Dim myParm As SqlParameter = custDA.UpdateCommand.Parameters.Add("@OldCustomerID", _ SqlDbType.NChar, 5, "CustomerID")myParm.SourceVersion = DataRowVersion.Original[C#]custDA.UpdateCommand.Parameters.Add("@CustomerID", SqlDbType.NChar, 5, "CustomerID"); custDA.UpdateCommand.Parameters.Add("@CompanyName", SqlDbType.NVarChar, 40, "CompanyName"); SqlParameter myParm = custDA.UpdateCommand.Parameters.Add("@OldCustomerID", SqlDbType.NChar, 5, "CustomerID");myParm.SourceVersion = DataRowVersion.Original; instead of above process, y cant v do above method in below procedure?

Hi,
I was trying to create a simple SP that return a single value as follows:CREATE PROCEDURE IsListingSaved@MemberID INT,@ListingID INTASIF EXISTS (SELECT [Member_ID] FROM [Member_Listing_Link] WHERE [Member_ID] = @MemberID AND [Listing_ID] = @ListingID) Return 1ELSE Return 0GOWhen I try it out in the Tableadapter's preview table, I get the correct result (1, where the entries exist). However, in the BLL, I tried to get the value as:Dim intResult as IntegerintResult = CType(Adapter.IsListingSaved(intMemberID, intListingID), Integer). However, this always returns 0 (when it should be returning 1). P.S. Curiously, breakpoints skipped the VS generated code for the adapter. What could be the problem? Thanks,Wild Thing
Hello all,
We have a Windows 2003 Web Edition server serving a site through IIS. It connects to a Windows 2003 Standard Edition server running SQL 2000 SP3a.
This site receives the following error as seen in the topic:
[DBNETLIB][ConnectionRead (recv()).]General network error. Check your network documentation.
We've configured the server network utility to only allow TCP/IP connections. The connection string for the site is as follows:
<%
' FileName="Connection_ado_conn_string.htm"
' Type="ADO"
' HTTP="false"
' Catalog=""
' Schema=""
MM_connSpankMSSQL_STRING = "Provider=sqloledb;Data Source=SERVER_IP,1433;Network Library=DBMSSOCN;Initial Catalog=ourmaindb_1;User ID=ourmaindb_1;Password=hotcookies;"
%>
Any ideas or tips on solving this issue? We've noticed it is due to larger queries as smaller ones do work with no problems.
The servers are behind a BSD box running iptables, has 1433,1434 along with standard web ports wide open. Anything outbound is allowed.
Some further testing via ODBC on the IIS server improved things. No more connection pooling for the SQL Server driver allows for 1/3 of the query to run. Still 2/3s of it doesn't show up, and that general network error message appears.
Should have 330 rows if it works right.

General Network Error. Check your network documentation
I have also searched many articles and tried following solutions but nothing working
- connectiontimeout = 0, max pool size = 7500/100, pooling = false
- SSL disabling enforce security false as mentioned in microsoft kb article.
And there's nothing any issue with hardware/firewall as my application's login and other forms are working fine(which use same database with same connection string)
Can any one please help me to solve this error?

I use sqlclient to connect directly from my mobile 5 pocketpc to a sql server 2005 database on my desktop.
I use a sqldatareader to traverse the results of a query that delivers 2 fields: (1) the filespec, and (2) the image field.
I use a filestream with a binary writer to write the contents of the image data to the pocketpc's storage card.
I have a test table with 10 images, not one more than 4 MB. I cannot complete a test run prior to receiving the general network error.
The pocketPC is connected via activesync to the desktop, and I connect to the database with:
Integrated Security=false;
user id=sa
password=admin.
Any help with this strange error would be greatly appreciated.

I am trying to grant various users permissions and am using the following sql command
GRANT Delete ON Resident TO hector AS barbara
barbara is a member of the fixed server role sysadmin and has Delete permission on the Resident table.
I log in to the server as barbara and try and execute this command and get:
Msg 15151, Level 16, State 1, Line 1
Cannot find the object 'Resident', because it does not exist or you do not have permission.
If I just run
GRANT Delete ON Resident TO hector
then everything works fine but the grantor is then dbo. I want to be able to have it recorded that barbara was the one that actually gave hector permissino to delete on the Resident table. Is there a way to do this?
