Disconnected Mirror / In Recovery

Apr 4, 2007

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!

Mirror And Witness Connection In A Disconnected State Immediately After Adding Witness Server To Mirror Session.

Jan 31, 2008


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,

Mirror Disconnected - Database Upgraded

Mar 14, 2007

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.

It was set up as a synchronise mirror

Mirror DB Goes To In Recovery When Set Partner Is Issued

Mar 27, 2008

We have a pair of SQL 2005 SP2 with Rollups clusters. We have a series of DB's that we are migrating from an existing SQL 2000 cluster. I have scripted the process, however on one of the test DB's, it goes to "In Recovery" as soon as I issue the Set Partner statement. There are other DB's on the same cluster mirrored with no problems. As we have a bunch of DB's to migrate, I want to figure out what would cause it to start a recovery. After the initial restores are done, it is in "Restoring" for a status so everything works up to that point.
Thanks

Recovery :: Mirror Of A Database Part Of AlwaysOn AG

Sep 14, 2015

We have an AG scenario where we are using WFC on a 2 node cluster. We are then using AG for mirroring the databases to both nodes and have a listener.

What I want to do next is to establish another copy of the database at a remote location. But I don't want to add the 3rd system to the WFC. I am not a big fan of WFC and I have seen it causes many more problems. The 3rd system will be in a remote location and the network not 100% reliable. I have seen in the past that it causes the entire cluster to hang and causing my production to crash which I don't want.

I there a way to add a 3rd node to the mirror configuration. I don't know if I can add a 3rd node to the AG unless it is part of the same cluster.

I know I can configure log shipping, I am fine with it but in the source, I have no control of which node the DB will be. I am not sure if a log shipping scenario can be configured using the listener instead of the physical host.

Mirroring :: Why DB Mirror Cannot Set DB Recovery Model To Simple

May 2, 2015

DB replication can set db recovery model to simple ,why db mirror can not  db recovery model to simple.

DB mirror must be set to full recovery model.

As far as I know, whatever db mirror  and db replication ,there is a log reader to read the log in the ldf file DB mirror and DB replication are almost the same principle to replicate the db to another db server.

Disconnected Record Sets

Oct 28, 1999

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?

Unable To Make Changes To Disconnected Recordset

May 16, 2007

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

Disconnected Data Store Options

Oct 4, 2007

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!

Recovery :: Server Local High Availability Using Failover Cluster And Disaster Recovery Using AlwaysOn

Aug 17, 2015

We have a requirement to build SQL environment which will give us local high availability and disaster recovery to second site. We have two sites- Site A & Site B. We are planning to have two nodes at Site A and 2 nodes at Site B. All four nodes will be part of same Windows failover cluster. We will build two SQL Cluster, InstanceA will be clustered between the nodes at Site A Server and InstanceB will be clustered between the nodes at Site B, we will enable Always On Between the InstanceA and InstanceB and will be primary owner where data will be written on InstanceA and will be replicated to InstaceB. URL....Now we want we will have instanceC on the Site B and data will be writen from the application available on Site B, will be replicated to the instance on the Site A as replica.

Keeping PK's Unique Across (potentially) Disconnected Sites.

Apr 17, 2008

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?

OLEDB Errors Using MS Access And Disconnected Recordset

Mar 31, 2004

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

<%
Const adLockBatchOptimistic = 4
Const adUseClient = 3

strDataBase = "somedb.mdb"

set cnTraining = server.CreateObject("ADODB.Connection")

cnnstr="Provider=Microsoft.Jet.OLEDB.4.0;User ID=Admin;Data Source=" & server.mappath(strDataBase) & ";Persist Security Info=False"

cnTraining.Mode = 3
cnTraining.Open cnnstr

set rsSearch = Server.CreateObject("ADODB.Recordset")
rsSearch.CursorLocation = adUseClient
rsSearch.LockType = adLockBatchOptimistic

sSql = "some sql stmt" 'this works fine on its own

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?

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?

After Moving To SQL2005, Disconnected Recordsets Are Ready-only

Feb 16, 2006

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.

Transact SQL :: Change Db In Recovery To No-recovery And Restore Transaction Log?

May 5, 2015

in the process of migrating a big db from server 1 to server 2, we had to roll back the change. I started with taking a full db backup and restoring it on server 2 with norecovery, and then a couple logs with norecovery, and then the last log with recovery.

Is there some way to continue this chain now, I mean to change the db to norecovery, or other way to restore logs. 

I dont want to do a new full backup.

If I try to do a log restore now i get the message:

Msg 3117, Level 16, State 4, Line 1

The log or differential backup cannot be restored because no files are ready to rollforward.

Msg 3013, Level 16, State 1, Line 1

.NET Class To Hold Single Disconnected Record? Nothing Smaller Than DataSet?

Jul 9, 2007

What is the most efficient standalone .NET class that can hold a single disconnected record?  The class must also retain column names, but other schema is not relevant (.NET data type is sufficient).If I understand System.Data.Common.DbDataRecord, it provides an interface on a DbDataReader, and has no storage of its own.I'm familiar with DataSet, is that the only .NET-standard class to do this? Thank you,Shannon

SQL Express 2005 Snapshot Replication On Disconnected/Closed Networks

Jul 9, 2007

I am having trouble setting up my Pull Subscription and I am new to replication.



I have several servers hosting a databased website that will be the same, except for user input and traffic. Quite simply, I need to copy most tables, SPs and data from network to network. I can't use FTP/Web synch ... as I mentioned the networks do not touch eachother or the internet.



On server Web1, it was easy to create a Publication called Pub via the wizard for my database: TheDB. Then on Web1, again, I added a Subscription to the Publication, indicating my second server, Web2, and the same database name: TheDB (I have already backed up and restored TheDB to all my servers). Here's one of the sp's I ran on Web1:



use [TheDB]

exec sp_addsubscription @publication = N'Pub', @subscriber = N'Web2'', @destination_db = N'TheDB', @sync_type = N'Automatic', @subscription_type = N'pull', @update_mode = N'read only'

GO



This is where I feel stuck. Using the wizard on Web2 doesn't allow me to see Web1. So I tried the following on Web2:

GO



I copied the snapshot folder, ie. 20070709134423, onto CD and moved it into Web2's default replication folder, but I always receive: cannot connect to Distibutor. I've tried using an Alias, as well, but don't understand exactly how I should point that either. I checked the publication's PAL and my Web2 user has rights and is an owner of the Web2 TheDB database.



Any help is appreciated.

Recovery :: AG Database In Reverting / In Recovery State

Nov 1, 2015

We have an issue with a 3 node SQL 2012 Always on availability group. Normal operation is node 1 (primary replica) with node 2 and node 3 as secondary replicas.After some patching, SQL wasn't running on node 1 hence the AG flipped over to node 2. This went unnoticed for some time and the transaction log for one of the AG databases became full on node 2 and node 3. (I think this is because it couldn't commit the transactions on node 1 so couldn't truncate it's t-log?) The DB is using synchronous replication btw.So I started SQL on node 1 and flipped the AG back to node 1 (with a data loss warning but I accepted this).Now the issue is that on node 2 and 3, the DB in question is stuck in a "Reverting / In Recovery" State. I've tried various commands such as ALTER DATABASE SET ONLINE, RESTORE DATABASE WITH RECOVERY etc but these fail stating unable to obtain a lock on the DB.

The weird thing is that on node 1 the state of the DB is "synchronised".how to resolve this issue on node 2 and 3? I've left them overnight (in case they were rolling back transactions, the DB is fairly large) but nothing seems to have happened. remove the DB from the AG in node 2 and 3 and add it back in again, ie recreate the replication?

SQL Server Admin 2014 :: Disconnected From Listener In Availability Group (When Primary Failed)

Jun 27, 2015

I setup an availability Group. (Only 2 servers - Primary And secondary) -- 21 , 22

I also define an listener . IP .. 23

1- In First step I connected To Listener (23) And in a while I inserted A record to a table .

While 1=1
insert into Tbl_T1(f1,f2) Values (1,2)

2- in second, I Stop the primary .

- I expected this while whitout disconnect, continue.

3- The while code stopped whit this message :

Msg 64, Level 20, State 0, Line 0 A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The specified network name is no longer available.)

4- I execute again the script, And it worked in new primary.

My questions :

1- is the listener disconnected between switched primary and secondary ? OR have we data loss between switching?

2- I did some huge update on Primary that fill the Log fiel space. And in last Update I got this error :

Msg 9002, Level 17, State 2, Line 27

The transaction log for database 'Your_DB' is full due to 'LOG_BACKUP'.

Is this (Fill All space) a reason to switch primary? Or not ?

If you are doing a disaster recovery of an entire SQL 2005 cluster, can you just install SQL server and restore the system database to get the configuration?
