Mirroring Partners Disconnected After Network Outage
Oct 25, 2007
We have mirroring set up on SQL 2005(SP2) on windows server 2003 servers for 6 production servers to DR servers. It is high performance mode(asynchonous). We are using fully qualified server names with default 5022 port. Prod and DR are using same domain service account.
We had network outage for about 30 minutes last weekend and after that network was restored back to normal. Also few SQL 2000 servers have logshipping and it automatically started syncing up after network was restored. However mirroring didn't start automatically. Partners were in disconnected state and endpoints were stopped. For one database, log grew to 40 GB using most of the disk space.
Then we maually had to run
ALTER ENDPOINT Mirroring STATE = STARTED
and then it started syncing up.
Now the question is why it doesn't start syncing up automatically after network is back to normal and recognize the partner?
Is there anyway we can setup timeout or any parameter like that to specify how many times or how long partners try to connect with no luck and then give up?

I've been working with sql server for some time, but couldn't find any way to fix this problem without rebooting the production and secondary sql servers, which is not very good for uptime .
I'm running a primary and secondary availability group on sql 2012 enterprise edition on windows server 2012, and it runs fine except when a network outage occurs.
Then the handshaking keeps failing, and the secondary databases all show not synchronizing.
The primary DBs all show synchronized.
I tried following several different troubleshooting guides for always on, but nothing I tried fixed the issue.
The only way to get them in sync is to reboot both primary and secondary. Just rebooting the secondary didn't fix it.
The secondary server error log showed AlwaysOn Availability Groups connection with primary DB established, then DB mirroring login succeeded, then error 35250, the connection to the primary replica is not active, then connection timeout.
I increased query connection timeouts to 60, but that didn't work.

We keep getting 3520's, etc. on the DR error log
How to eliminate all these prod reboots?

I would like to know people's thoughts on any special network considerations to take for mirroring and the logic behind them. Is it best to segregate mirroring traffic from other network traffic? Use a VLAN? Dedicate one NIC for mirroring and the other for general network traffic or just aggregate the two and let both types of traffic share the bandwidth?
I haven't seen much in this area from Microsoft's best practices and wanted to know what those who have implemented it have done and why. There are pros and cons for each method: Letting everything share one massive pipe with load balancing vs. trying to segregate traffic in some way so that general network connections etc. do not impact the mirroring capability.
I look forward to hearing from you.

We have a database in SQL Server 2008 R2 with mirroring and want that replication is done by dedicated network.We stop the endpoint and when we try to run the following command, syntax error occurred:
Msg 102, Level 15, State 1, Line 1
Incorrect syntax near '192.168.1.14'.
What is the correct syntax of the command line below?
ALTER ENDPOINT Endpoint_Mirroring AS TCP (LISTENER_IP = '192.168.1.14')

I have a SQL server that's partly managed by another team for their vendored application. Anyway, they're having some weird issues with performance. Last weekend a guy tripped over the power cord (duh!). I looked at the logs and there were no recovery errors on restart and it seems to be running fine..
I'm looking for help on any diagnostics I can run to check anything else out?
Thanks,

Yes, I know synchronisation to alternate partners is deprecated in SQL2005 but....
In SQL2000 there is a Sync Partners tab in the publication properties dialog that allows you tick a checkbox for each co-publisher to be enabled as an alternate synchronisation partner. What is the equivalent in SQL2005?
I've set up replication in SQL2000 following these instructions http://support.microsoft.com/?kbid=321176 and it works. Now I'm trying to do the same thing in SQL2005 but I can't find a substitute for steps 10 & 11 in the section "Set Up the Alternate Synchronisation Partner". What's the answer?
Thanks in advance.

I have a requirement to calculate the total outage time, based on logged fault tickets, of network nodes. Basically, multiple tickets may be raised for a single node and those tickets could overlap or sequence over a given period; the task here is to calculate the total time (hh:mm) of the outage in the period.
Ex:
3 tickets raised for a node outage over, say, a 48 hour period. Ticket 1 (spanning a total of 5 hours) overlaps with ticket 2 (spans 3 hours) by 1 hour; ticket 3 starts 5 hours after ticket 2 and spans 1 hour. Total outage time on the tickets is 7hrs + 1hr (T1+T2 minus the 1hr overlap) and the full time of T3.
In summary, it's calculating the total ticket time, allowing for overlaps of tickets, etc.

Hello,
I have un problem with the mirroring, when I set the IP of the partners, I get an error saying that the server will not exists or it's impossible to join it. I try to make a mirroring without witness between two servers.
request on first :
ALTER DATABASE [panorama2] SET PARTNER = N'TCP://192.168.1.71:5050'
I get :
Msg1418, Niveau16, tat1, Ligne1L'adresse reseau du serveur "TCP://192.168.1.71:5050" est impossible à atteindre ou elle n'existe pas. Verifiez le nom de l'adresse reseau et executez la commande de nouveau.
And it's the same problem with the second server.
I work with the sql server evaluation (I put the parameter T 1400 for). Endpoints are created (I get them with a select on systcp_endpoints) :
Mirroring 65541 1 2 TCP 4 DATABASE_MIRRORING 0 STARTED 0 5050 0 NULL
Thanks for helping.
ps : Excuse my english ^^

We've been running a mirrored database (using certificates since we don't have a domain) and it's all working well. Last week we decided to add a witness for automatic failovers, but for some reason I just can not get the witness to connect to the Partner2 server.
See screenshot here
Please help me troubleshoot this - I re-created the endpoints / users / certificates but it's still not working. Where can I get more information on what exactly the problem is? Can I test the endpoints somehow?

I have two instances (Source and Destination) on the same server, i did a full backup of a database on the source server, i did a restore on the destination using the NORECOVERY mode, now the database on the destination as green arrow saying "restoring". From the source database i set up the mirroring, i'm using port 5022 on source and 5023 on destination, everything seems to connect fine but when i start mirroring i get the error message "Database mirroring cannot be enabled because the database is not full recovery error: 1465" but when i look at the property of the db on the source the recovery model shows full as so the destination?

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 actually work in an organisation and we have to find a solution about the data consistancy in the database. our partners use to send details to the organisation and inserted directly in the database, so we want to create a new database as a buffer database to insert informations from the partners then make an update to the main database. is there a better solution instead of that?

We're constructing a three-tier application. We want the middle tier to
extract a recordset from the database, disconnect from the database,
then pass the recordset to the front tier. After changes have been made
by the front tier, it will pass the recordset back to the middle tier,
which will reconnect, and update the database.
The problem:
Using stored procedures, the recordset is no longer available
once the connection has been closed. Is there any way, using stored
procedures, to be able to keep the recordset available after the
connection has been closed, either by preserving it, copying it, or
otherwise?

Hello,
I'm having a problem with two mirrored databases, using SQL Server 2005 SP2, that autmatically failed over last night for unknown reasons. I was trying to fail them back over to the primary SQL server because it says the mirror is disconnected and out of sync. Other databases failed over too, but I was able to fail those back over without a problem. It's just these two. I removed the mirror from the secondary server thinking that this would allow me to restore the database back on the primary server, but that didn't help.
These two databases show a status of (Principal, Disconnected / In Recovery) and I still cannot do anything with the two databases on the primary server. When I try to pull up the properties for them, I get the following error:
"Database <Name> is enabled for Database Mirroring, but neither the partner nor the witness server instances are available: the database cannot be opened.(Microsoft SQL Server, Error: 955)"
I cannot delete, detach, Alter or do anything with the databases. If I could just delete them that would be fine so I can just do a restore, but I can't seem to do anything.
Does anyone know what I can do to resolve this problem.
Thanks in advance!
-Jay

Its been almost 10 years since I have had to do work with good-old RecordSet objects...
I am filling a RecordSet with data returned from a SQL server via a stored procedure. I then set the ActiveConnection property to Nothing in order to disconnect it so I can make changes to it.
But when I try to set the value on a given row I get back a "Multiple-step operation generated errors. Check each status value" error message. My understanding is that this is indicative of trying to use the wrong datatype. I have verified that the type is correct (I am dealing with integers) so I am at a loss for what the problem could be.
Here is my code:
Set rsPackages = CreateObject("ADODB.RecordSet")
rsPackages.CursorLocation = adUseClient
rsPackages.LockType = adLockBatchOptimistic
rsPackages.Open "EXECUTE stp_FetchPackageData", myConn
rsPackages.ActiveConnection = Nothing
Response.Write("Value: " & rsPackages("TotalCount")) ' returns 0
Response.Write("Data Type : " & rsPackages.Fields("TotalCount").Type) ' returns 3 = adInteger
rsPackages("TotalCount") = 1 ' throws multi-step error
Oddly enough, when I look at the Attribute property of the field I get back a value of 112. When you break it down I think that value indicates the row value is read-only? (Could that be my problem? Just a really bad/unhelpful error message?) But if I try to change it I get back a message saying cannot be done since RecordSet is already open.
Thanks,
Jason

I have a .Net database application that we've successfully deployed in a connected environment. Now we have a client that has the need to store data on a central SQL Server and publish that data out to tablet PC's that will be able to disconnect from the central SQL Server. At some point those tablet PC's will come back in and connect to the central server via VPN and will need to push their changes back to the server. Some fundamental questions:
1) Am I correct in assuming that replication is the best way to accomplish this?
If so,
2) Which replication type sounds appropriate to the above scenario?
3) Am I correct in assuming that the tablet PC's will need some version of SQL Server to support editing of the data in the disconnected state?
My perhaps incorrect first take on this was that we could use a licensed SQL Server on the central server and SQL Server Express as a replication subscriber on the tablet PC's.
Any guidance greatly appreciated!

Hi
While a database upgrade schema changes were being made the Mirror became disconnected will this recover itself when it reconnects or will it be the case that we will have to copy the db files to the Mirror and set it up from scratch.

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.

Hi Every one,
I am using .Net 1.1 for my web application.
And my database server is SQL Server 2005.
My application is running fine, as i can login to it and also able to view pages. But when i open Order management(having 3K records) its give me error,
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?

Hi All,
I'd like to throw this idea 'out there' to see if I'm missing something I'll later regret.
I'm looking to resolve a scalability issue within our point-of-sale program. Currently the PK on transactional tables (sales and orders) is created by the application layer using a 'MAX(PKCol) + 1' mechanism. Obviously this requires that all users of the system, whether they're local or remote, have current data at any time they wish to insert. It's this limitation I'd like to remove. Most sites are using MS SQL Server 2000. No sites use anything specific to a later version.
By having a PK that can be generated independently of a 'master' database we can overcome this issue. The PK values will need to be unique within a 'group' of shops and able to be generated by a program operating at any level. From 'head office' which manages a number of shops, to the server at a given shop and even the register / till itself should be able to create ID's while disconnected from the server (using a local database).
It seems there's three main ways to accomplish this:
- Identities,
- MachineID, CurrentPK composite.
- GUID's
Identities: I've ruled out identities as I believe the administration overhead of dealing with them makes them impractical (there may be several hundred registers and therefore as many ranges to be set up within a group).
MachineID, CurrentPK composite: The MachineID references a Machine table which has an entry for each ethernet MAC address which connects to the database. The reason I chose to store the MAC in another table rather than simply using it as column is that I'm fetching it from sysprocesses.net_address(nchar(12)) and believe it's computationally cheaper to use an int than a text column. This mechanism means that we can still expose the PK to the user in some cases (eg: InvoiceNumber printed on a receipt). When the local database is not up to date (usually due to network problems) there will be cases where the CurrentPK will be duplicated but kept unique since it's coupled with the new MachineID. The big drawback to this method is that all current code will need to be revised to deal with the composite keys (this will be a significant amount of development).
GUIDs: Ugly to look at and time-consuming to type. They're not something which you'd expose to a user unmodified so realistically this means altering existing code to use a new 'user friendly' number where the PK is currently exposed to them. The use of GUIDs rule-out the use of clustered indecies on tables they're the PK for lest most inserts cause a page split. The splits would also necessitate more frequent index defrags / rebuilds. Using a non-clustered index incurs a penalty Vs a non-fragmented clustered one (doesn't it?) so while this avoids page-splits it comes at a cost.
After all that I think the best solution is to use GUIDs with a non-clustered index for each of the PK's. While it might not be the fastest of the options (slower reads/joins Vs composite PK) it will be significantly faster to develop while maintaining acceptable performance.
Thoughts?

Hello, Code below returns the following error:
Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done

rsSearch.Open sSql, cnTraining
set rsSearch.ActiveConnection = nothing
cnTraining.Close
set cnTraining = nothing
%>
My goal is to get a disconnected recordset. The problem here occurs when i try to use the adUseClient value (3) for the CursorLocation. If I don't use a 3 in the CursorLocation it works fine. Hoewever i'm almost certain i have to use the 3 in order to disconnect the recordset. Any ideas? Is my connection string not set up properly to get a disconnected recordset?

We're using ADO disconnected recordsets. On SQL 2000, we could update these on the client (without propagating the changes to the server) even if the underlying view or table was non-updatable.
When running our apps against SQL 2005 (using the same client-side environment), we can no longer change any attributes of those disconnected recordsets, that connect to a non-updatable database object (the rest of the app runs fine, we can update all updatable database objects through disconnected recordsets) . Does SQL 2005 respond to such calls differently from SQL 2000, so that ADO recordsets are built in a new way (which makes them read-only in our setting)?
Thanks for any suggestions.
