Distributed Transactions With Multiple Instances Of Microsoft SQL Server
Jul 23, 2005
Hi,
I'm having a problem running a distributed transaction between two
linked servers that both have multiple instances of SQL Server
installed on them. This is the error message that I receive:
"The operation could not be performed because the OLE DB provider
'SQLOLEDB' was unable to begin a distributed transaction.
[OLE/DB provider returned message: New transaction cannot enlist in the
specified transaction coordinator. ]
OLE DB error trace [OLE/DB Provider 'SQLOLEDB'
ITransactionJoin::JoinTransaction returned 0x8004d00a]."
The query follows the format:
"BEGIN DISTRIBUTED TRAN
UPDATE [LINKEDSERVER1INSTANCE_NAME].DB.OWNER.TABLENAME
SET fieldname = alias2.fieldname
FROM tablename alias2
JOIN [LINKEDSERVER1INSTANCE_NAME].DB.OWNER.TABLENAME alias1
on alias2.urn=alias1,urn"
[color=blue]
>From what I can gather from various sources the SQL Server must be[/color]
named the same as the computer which it is installed on. However, if I
have two instances of SQL Server, they cannot both be named the same as
the computer. Does anyone know of a way around this or whether I'm
barking up the wrong tree completely?
I am using distributed transactions where in I start a TransactionScope in BLL and receive data from service broker queue in DAL, perform various actions in BLL and DAL and if everything is ok call TransactionScope.Commit().
I have a problem where in if i run multiple instances of the same app ( each app creates one thread ), the threads pop out the same message and I get a deadlock upon commit.
My dequeue SP is as follows:
CREATE PROC [dbo].[queue_dequeue] @entryId int OUTPUT AS BEGIN DECLARE @conversationHandle UNIQUEIDENTIFIER; DECLARE @messageTypeName SYSNAME; DECLARE @conversationGroupId UNIQUEIDENTIFIER;
GET CONVERSATION GROUP @conversationGroupId FROM ProcessingQueue; if (@conversationGroupId is not null) BEGIN RECEIVE TOP(1) @entryId = CONVERT(INT, [message_body]), @conversationHandle = [conversation_handle], @messageTypeName = [message_type_name] FROM ProcessingQueue WHERE conversation_group_id=@conversationGroupId END
if @messageTypeName in ( 'http://schemas.microsoft.com/SQL/ServiceBroker/EndDialog', 'http://schemas.microsoft.com/SQL/ServiceBroker/Error' ) begin end conversation @conversationHandle; end END
Can anyone explain to me why the threads are able to pop the same message ? I thought service broker made sure this cannot happen?
We get the below error while performing a distributed transaction on linked server. We have several linked servers configured in the source server and all of them succeed with the distributed transaction except on one.
We did all the basic troubleshooting and moreover the distributed transactions work fine if we use a remote server instead.
Error: OLE DB provider "SQLNCLI10" for linked server "SERVERNAME.REDMOND.CORP.MICROSOFT.COM" returned message "No transaction is active.". Msg 7391, Level 16, State 2, Line 3 The operation could not be performed because OLE DB provider "SQLNCLI10" for linked server "SERVERNAME.REDMOND.CORP.MICROSOFT.COM" was unable to begin a distributed transaction.

Hi to everyone! Any experience handling a Store Procedure that has distribution transactions? Here is a story.
We have a store procedure #1 that inserts or updates data in two tables A and B on SQL Server 7.0 then it calls another store procedure #2 that: 1. updates C table in the same database on SQL Server from Oracle Server 2. deletes that record on Oracle Server 3. inserts a record on Oracle from table A 4. inserts the same record into table D on SQL Server from Oracle Server.
People who wrote store procedure #1 put Commit Tran before executing #2. The questions are: 1. Is it correct that we don't have Commit Tran for #2? 2. What do you think about Nested Begin - Commit Tran?
Does SQL Server actually support distributed transactions over, say, two tables in different databases but that reside on the same server? When I try to execute such a transaction in which one part of the transaction violates referential integrity and hence should not be executed, causing the rest of the transaction to, supposedly, rollback, the transaction does not roll back but instead produces an error message and executes the second, valid half of the transaction anyway. Any help or suggestions gratefully accepted.
I realize this is probably a basic question or at least i hope so but i cannot get distributed transactions working.
BOL is just driving me in circles. I am running SS2000, MSDTC is up and running on the server.
I have added a trigger to a table where on insert or update the triggers fires and inserts a row to a remote server.
When i execute the update or insert i get the error: Cannot start a distributed transaction.
I have tried stating BEGIN DISTRIBUTED TRANSACTION before the update but i get the same error, i have also read up on SET REMOTE_PROC_TRANSACTIONS, but this is not a remote sp.
Can anyone please reccomend a good link as to how to get distributed transactions to work.
I am writing an interface between SQL Server and Access. I have chosen to use a linked server using the Microsoft.Jet.OLEDB.4.0 provider. One of the requirements is to have multiple SQL statements in one transaction, which is where I am encountering the problem. (see below)
BEGIN TRAN
INSERT INTO ACCES...Table
Msg 7390, Level 16, State 2, Line 2
The requested operation could not be performed because OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "HES" does not support the required transaction interface.
I am having a really really hard time finding documentation on the Microsoft.Jet.OLEDB.4.0 provider, specifically I want to know for sure if it supports the ITransactionJoin interface.
The main question is - does MS Access linked servers support transactions?
Thank you for your help,
I have exausted all resources available to me in finding out the answer.
I am trying to configure distributed transaction and XA support using Microsoft SQL Server 2005 JDBC Driver. I have coppied SQLJDBC_XA.dll from XA directory and placed in my sql server binn directory and trying to run the script xa_install.sql from binn directory with command as below :
But I am getting error saying : [DBNETLIB]SQL Server does not exist or access denied. [DBNETLIB]ConnectionOpen (Connect()).
when I replaced local host with the machine name it gives error : [Shared Memory]SQL Server does not exist or access denied. [Shared Memory]ConnectionOpen (Connect()).
where in I am able to test connection from Websphere using the same connection.
Please help some one ....... I am in URGENT need.... I need to enable XA suport for my application to run........
I am using SQL server 7.0 and i have created oracle8i linked server(Using MSDAORA as provider) in it. When i run distributed queries between SQl server and Oracle server it works fine.But when i try to run distributed transaction between two servers ( BEGIN DISTRIBUTED TRANSACTION..)it reports an error saying Distributed transactions are not supported by MSDAORA.
My question is; is it possible to run distributed transaction between SQL server and oracle server (where oracle server is a linked server in my SQL server)?
Actually i want to run this transaction in DTS package which updates and transfers data amongst various servers.
We just upgraded from SQL 7 to 2000 and for some reason I am unable to perform distributed transactions. I keep getting the following error:
OLE DB error trace [OLE/DB Provider 'MSDASQL' ITransaction Join:: JoinTransaction returned 0x8004d00a]. Operation could not be performed because the OLE DB provider 'MSDASQL' was unable to begin a distributed transaction
I tried a few of the fixes recommended on the microsoft website but they did not solve the problem. We are still using the same O/S (Windows 2000 Pro), so the only thing that has changed is the server.
I am attempting to update an oracle table from a insert trigger on my SQL table. When using a trigger to run a sql command against the ole db oracle client (linked server) a distributed transaction is initiated and i get a message stating. "The operation could not be performed because the OLE DB provider 'MSDAORA' was unable to begin a distributed transaction."
I can update the oracle table through a query however just not throught a distributed transaction.
However according to all the documentation i can find it states that I should be able to perform this.
I've been redirected here from the Transaction Programming forum becuase I have e peculiar issue with SQL 2005 running INSERT stored procs from multiple WCF services all withing a TransactionScope.
The original post is http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2720665&SiteID=1&mode=1
The story goes, I have SRVC A with starts a TransactionScope which in turn calls SRVC B & C in sequence based on processing rules.
SRVC A is a Sequential Workflow which Starts and Completes the TransactionScope SRVC B Creates a new Customer into the database SRVC C Creates new Accounts for that Customer and Initialises the accounts with funds
The DB Tables underneath are Customer, Account and AccountLog
DDL
Code Block CREATE TABLE [Member].[Customers](
[CustomerId] [int] IDENTITY(1,1) NOT NULL, [Name] [varchar](32) NOT NULL, [CreatedUtc] [datetime] NOT NULL ,
CONSTRAINT [PK_Customer] PRIMARY KEY CLUSTERED (
[CustomerId] ASC )
CREATE TABLE [Bank].[Accounts](
[AccountId] [int] IDENTITY(1,1) NOT NULL, [CustomerId] [int] NOT NULL, [CurrentBalance] [money] NOT NULL, [LastUpdateDate] [datetime] NULL, [CreatedDate] [datetime] NOT NULL, [timestamp] [timestamp] NOT NULL, CONSTRAINT [PK_Bank_Account] PRIMARY KEY CLUSTERED (
[AccountId] ASC )
) ON [PRIMARY] GO ALTER TABLE [Bank].[Accounts] WITH CHECK ADD CONSTRAINT [FK_Account_Customer] FOREIGN KEY([CustomerId]) REFERENCES [Member].[Customers] ([CustomerId])
CREATE TABLE [Bank].[AccountLog](
[AccountLogId] [int] IDENTITY(1,1) NOT NULL, [AccountId] [int] NOT NULL, [Amount] [money] NOT NULL, [UtcDate] [datetime] NOT NULL, CONSTRAINT [PK_Bank_AccountLog] PRIMARY KEY CLUSTERED (
[AccountLogId] ASC ) ) ON [PRIMARY] GO ALTER TABLE [Bank].[AccountLog] WITH CHECK ADD CONSTRAINT [FK_AccountLog_Account] FOREIGN KEY([AccountId]) REFERENCES [Bank].[Accounts] ([AccountId])
NB. I've removed most fields not essential for this example.
So from SRVC A I invoke SRVC B and the Customer is created, however when I get to SRVC C and the accounts are to be created I get a lock. Only when the Transaction aborts due to timeout, do I see in SQL Profiler that the call to the SP that created the Account is executed but eventually rolls back as it is part of the distributed transaction.
Now, If I set the Isolation level in the TransactionScope to ReadUncommitted (urgh) the problem remains. When I set the IsolationLevel to Read Uncommitted in the SP that creates the account the problem remains but when I remove the FK constraint the problem disappers. The other curious thing is that with the Customer -> Account FK removed and when SRVC C calls to insert funds into the AccountLog which also updates an aggregated total in the Account from within the same transaction scope and with Account -> AccountLog FK constraints in place there is no locking even with Isolation Serializable.
I'm quite at a loss as to what could be causing these issues. If anyone has any suggestions I would greatly appreciate any help.
Distributed transactions were happily running between our SQL servers and then we installed Windows 2003 Server SP2 and all of a sudden we got this nice error message when attempting a remote data update via linked servers. I couldn't even run "BEGIN DISTRIBUTED TRANSACTION" without getting the error message. The full error message is:
"Enlist operation failed: 0x8004d00e(XACT_E_NOTRANSACTION). SQL Server could not register with Microsoft Distributed Transaction Coordinator (MSDTC) as a resource manager for this transaction. The transaction may have been stopped by the client or the resource manager."
Apparently, SP2 disables network DTC access (how nice, I feel more secure knowing that my data can't be updated remotely anymore).
Solution:
From Control Panel | Add or Remove Programs | Add Remove Windows Components Select "Application Server" and click the "Details" button Check "Enable network DTC access" and click OK for however many prompts it takes to apply the changes.
****NOTE**** this change WILL SHUT DOWN SQL SERVER so plan accordingly (this would have been handy to know in advance since I ran it in the middle of the workday and everyone got disconnected).
I found the following link which seems to be the problem we're experiencinghttp://support.microsoft.com/kb/937517
The link includes a workaround which is the following: "To prevent the SQLNCLI provider from sending an attention signal to the server, use the SQLNCLI provider to consume fully any rowsets that the OLE DB consumer creates. "
How do I use the SQLNCLI provider to fully consume any rowsets?
I have two SQL servers, SERVERA and SERVERB. They are on two different VLAN's within our corporate network. They are physically only about 5 feet apart. SERVERA is SQL2005 while SERVERB is SQL2000. I am running a distruted transaction as a result of an insert on SERVERA which then causes a Stored procedure stored on SERVERA to insert a record on a table on SERVERB. I know my syntax is correct, 'cause I can get the Process to work between two servers (one SQL2000 and the other SQL2005) on the same VLAN. But when I run it in the problem environment, I get the following error message:
SQL Execution Error
Executed SQL Statement: INSERT INTO Tablea(recordid, recordtext) values(3, 'Testagain')
Error source: .Net SQLClient Data Provider
Error Message: The operation could not be performed because OLE DB provider "SQLNCL1" for linked server "SERVERB" was unable to being a distributed transaction.
I have checked to make sure that MSDTC is running and it is on both servers.
Any help would be greatly appreciated. Thanks! - Eric-
We have two servers, one (we'll call 'SERVERA') has SQL2005 running on it. The second (we'll call 'YELLOWSTEONE') is running both SQL2000 and SQL2005 on it. The SQL instances on YELLOWSTONE are 'YELLOWSTONESQL2000' and 'YELLOWSTONESQL2005'. As a linked server, I have an entry for YELLOWSTONE which then links to the SQL Server of YELLOWSTONESQL2000 on the server network name of YELLOWSTONE. By them selves they seem to run fine. However, if I have trigger that Runs on SERVERA to do a distributed transaction on 'YELLOWSTONESQL2000', I get the following error:
OLE DB provider "SQLNCLI" for linked server "YELLOWSTONE" returned message "Login timeout expired".
OLE DB provider "SQLNCLI" for linked server "YELLOWSTONE" returned message "An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.".
Msg 2, Level 16, State 1, Line 0
Named Pipes Provider: Could not open a connection to SQL Server [2].
If You can provide me any assistance, I would greatly appreciate it. Thanks! - Eric -
I think this is a question for the specialists among us.
Can I use one general reporting server (installed on instance MAINREPORTING) for multiple customers who all have their own sql instance (CUST1, CUST2, CUST3, ..) I would use UserAuthenciation on the reportserver url to display the specific reports customers can use.
Is this possible, and what do i have to take care off concerning installation and/or configuration (especially on the reporting side) ?
Hi, I am working on vs2005 with sql server 2000. I have used TransactionScope class. Example Reference: http://www.c-sharpcorner.com/UploadFile/mosessaur/TransactionScope04142006103850AM/TransactionScope.aspx The code is given below. using System.Transactions; protected void Page_Load(object sender, EventArgs e) { System.Transactions.TransactionOptions transOption = new System.Transactions.TransactionOptions(); transOption.IsolationLevel = System.Transactions.IsolationLevel.ReadCommitted; transOption.Timeout = new TimeSpan(0, 2, 0); using (System.Transactions.TransactionScope tranScope = new System.Transactions.TransactionScope(TransactionScopeOption.Required,transOption)) { using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["nwConnString"].ConnectionString)) { int i; con.Open(); SqlCommand cmd = new SqlCommand("update products set unitsinstock=100 where productid=1", con); i = cmd.ExecuteNonQuery(); if (i > 0) { using (SqlConnection conInner = new SqlConnection(ConfigurationManager.ConnectionStrings["pubsConnString"].ConnectionString)) { conInner.Open(); SqlCommand cmdInner = new SqlCommand("update Salary set sal=5000 where eno=1", conInner); i = cmdInner.ExecuteNonQuery(); if (i > 0) { tranScope.Complete(); // this statement commits the executed query. } } } } // Dispose TransactionScope object, to commit or rollback transaction. } } It gives error like "The partner transaction manager has disabled its support for remote/network transactions. (Exception from HRESULT: 0x8004D025)" The database I have used is northwind database and pubs database which is by default in sql server 2000. So, Kindly let me know how to proceed further. Thanks in advance,Arun.
Hi,I am seeking the help of volunteers to test some software that I'vedeveloped which facilitates distributed two-phase commit transactions,encompassing any resource manager (e.g. SQL/Server or Oracle) controlled byMicrosoft's Distributed Transaction Coordinator in a Windows2000environment, with any resource manager under the control of DECdtm (e.g. Rdb(or Oracle via the XA Veneer)) in a VMS environment.[Yes, at some stage, I hope to sell this software and make money out of it,so unless you have a large philanthropic streak or are simply a techie wholikes to stay on top of Windows<->VMS connectivity issues, then you may wishto look away now. But if you do choose to participate, then rest assuredthat I have no interest in your personal or company details. (Just yourwork-rate :-)]What differentiates my Transaction Manager software from existingTransaction Monitor packages that are already in the marketplace (and whyyou should be interested) is that it is based on the Transaction InternetProtocol TIP standard. (RFC 2372) For those of you who don't know, thebeauty of TIP's "Two-Pipe" strategy is it's application-pipe (or middleware)neutrality. Whereas most XA implementations mandate homogenous TransactionMonitor deployments (such as Tuxedo everywhere, Encina everywhere, MQSerieseverywhere, ACMSxp everywhere and so on . . .), hotTIP from TIER3 Softwaregives you complete freedom to choose the middleware product(s) that bestsuite your particular application and heterogeneous network needs.Would you like to talk to VMS with TIER3 Sockets, COM or DCE/RPC? BEAMessageQ, IBM MQSeries or HTML? The choice is yours and yours alone. Butonce you realize that you need to encase your critical transactions withinthe ACID properties of a true Heterogeneous Two-Phase Commit then you willcome to the conclusion that you need a Transaction Manager that looks a lotlike this.Another drawback of traditional "One-Pipe" strategies is that they precludethe run-time determination of transaction participants. (Functionalitywhich may be advantageous in a wide-area or Internet based application.)Anyway, this is what I have: -On the Windows side, you need absolutely *NO* additional software! I'llreply to this note with a brief description of the COM+ and DTC functionsthat you would need to invoke in order to successfully push a MTS/DTCtransaction to VMS. NB: These are standard Windows APIs that are fullydocumented on MSDN.On the VMS side, I have a VMSINSTAL saveset that (all zipped up) is some150KB that I'm happy to e-mail to you along similar lines to the VMShobbyists (non-commercial use) license. I'll reply to this note with anInternet Daemon (INETd) example of code that uses my software to cedetransactional control, over an SQL insert into a Rdb database, to MTS/DTC.It's under 500 lines long and contains all of the DCL, 3GL, SQL required toproduce a working example of a TIP-2PC capable TCP/IP auxiliary server. Thisexample will insert a row into the MF_PERSONNEL.Employees table on the VMSside in co-operation with Windows2000 MTS/DTC client that is inserting a rowinto the NORTHWIND.Employee table. Commit them all or roll them all back.So, in summary, If you'd like to volunteer to put hotTIP through it's pacesthen simply reply to this mail.Regards Richard MaherPS. The following are a few functionality restrictions with the currentversion of my software that may effect your decision to participate: -1) Transaction has to be started/mastered/coordinated by W2K MTS/DTC2) Transactions cannot be PULLed from VMS and must be PUSHed from W2K3) No cluster-wide recovery.(If a txn falls over after being prepared then you have to wait for thatspecific node to become contactable again even though that lovely RDMrecovery job is sitting on another node protecting the database until myhotTIP TM tells it to commit or abort.)4) There is currently no Alpha or Itanium version available. The Alpha portis currently in progress but, for the time being, you'll either need a VAXor a VAX emulator on your PC.
It is my understanding that when having LinkedServers, the option "enable promotion of Distributed Transactions for RPC" should be set to TRUE, so we can rollback , if needed, remote transactions. At least, that's my understanding of that setting.
Having said that, the TRUE setting is affecting this particular TSQL code, inside an sproc, which I would prefer not to alter:
Insert into #TempTable EXEC ServerB.MyDatabase.MyStoreProcedure @param1= '', @param2= '' When set is set to TRUE (current setting) I get this error:
OLE DB provider "SQLNCLI11" for linked server "ServerB" returned message "The partner transaction manager has disabled its support for remote/network transactions.". Msg 7391, Level 16, State 2, Line 28
The operation could not be performed because OLE DB provider "SQLNCLI11" for linked server "ServerB" was unable to begin a distributed transaction.
I am running SQL 7.0 as the default instance and SQL 2K as a named instance. Each is using a different port....7.0 is using port 1433 and 2K is using 1024. Everything appears to be up and running fine on the server. However, I am not able to access the 2K instance from a client. I have tried to use both TCP IP and named pipes setting them up using the server network utility and the client network utility. No luck anywhere. I continue to get connection errors...check network documentation...
Is there any limit on SQL server Multiple Instances? if we require to run 60+ Instances on single machine what will be the minimum hardware requirements.
1.) Is it possible to install Analysis Services on multiple SQL Server 2000 instances? If it is, then can you instruct me as to how to perform the install. If it is not possible, then does one restrict access to cube data via the Database Role Manager?
ie. The host box is - DOILAB30 with Analysis Services & SP2 Instance - DOILAB30/DOILAB30_FIN (Can AS be installed here?)
Do I severely restrict the membership of OLAP Admins?
2). Re. AS maintenance. - How do I backup and restore OLAP dbs/cubes etc. Following a restore, what issues, such as cube users/permissions should I be aware of? (if any).
There are several instances in SQL Server. I use RDA method to access SQL Server from mobile devices. But RDA method only gets the server IP,not the instance name. So, how can I define RDA to access to the instance that I need?
I am trying to built a general demo machine for our multiple resellers.
Is it possible to have multiple database instances (one per reseller) with each of them their own reporting instance, running on the same server (also same IIS). In our DNS and in the IIS settings i will reroute the specific reseller to his specific reporting url (eg: http://www.demosite.reseller1.com/reports (this is not a real url), will be rerouted via dns to the specific reporting url for reseller one ... and so on.)
Each reseller must be able to has it own reports, subscriptions, models and access to reportbuilder.
Can this be accomplished ?
I have tried already a few times but get stuck when i want to upload reports/datasources to the specific websites. Also i have encountered the fact that if i succeed in uploading data to one reporting site and i want to upload different data to another site, the initial site is also changed with the data of the second upload.
Can anyone point me into the right direction how to solve this problem .
I am trying to updated data on a different database on a different server. I am using linked servers for this. I can do select,updated , insert using the linked server in the management console but when i try to update the tables on remote server thru trigger i get this message MSDTC on server 'myserver' is unavailable. i checked the distributed transaction co-ordinator service in services.msc and its show that its running. Then i checked the logs in sql server 2005 and i see the following message
"The Microsoft Distributed Transaction Coordinator (MS DTC) service could not be contacted. If you would like distributed transaction functionality, please start this service."
i also see the the red stop icon on the distributed transaction co ordinator in under management in sql server 2005. i have enabled remote proc trans using sp_configure
Can a MIRROR server have mirrored databases on many instances or must all of the mirrored databases on a server reside on one instance?
This initial implementation worked fine:
PRINCIPAL ServerPROD1instance01 endpoint1430 MIRROR ServerDRinstance01 endpoint1440 WITNESS ServerZ endpoint1450
This second implementation (different PRINCIPAL server to same MIRROR but to a different instance)
PRINCIPAL ServerPROD2instance5 endpoint1430 MIRROR ServerDRinstance02 endpoint1440 <<same mirror server but different instance WITNESS ServerZ endpoint1450
I know that you can only install one endpoint on each server. Does that mean that the endpoint can only resolve to one instance though?
The second implementation looks fine until the final step (start mirroring). I get the following error:
An error occured while starting mirroring Alter failed for database 'test' An exception occurred while executing transaction-sql statement or batch The remote copy of database 'test' does not exist. Check the database name and resissue the command
I have created the test database in instance02 and rolled a log onto it. It is currently in recovery mode - waiting patiently for another log.....
I have read books online and 2k5 unleashed but can't see anything that relates to an implementation across mutliple instances on the DRmirrored servers.
Has anyone tried to do this? Can you confirm its possible?
Is it possible to have more than one instance of SQL Server on a failover Active/Passive cluster? What are the concerns/ramifications if that indeed is possible?
Greetings... I'm working at consolidating several Reporting Services installations into one so we can decommission some old servers. We have two Report Servers that are in SQL Server 2000 and three that are in SQL Server 2005 (none are in a web farm configuration). I can upgrade the 2000 databases to 2005 format just fine, but now how do I merge these five ReportServer/ReportServerTempDB databases into one? I'm reluctant to redeploy reports to the "official" Report Server because we lose security, subscription, and scheduling information by doing that. So redeploy would cost us time and data loss over hundreds of reports, thus my hope to merge the databases at a data level. Is there a tool to automate this process, or has anyone tried this before? Thanks in advance.
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?
