How To Configure Distributor Thread For Being Up While Replicated Database Is Down
May 1, 2006
Hi
I often deal with a problem when replicated database is down due to
electric outage or any other scheduled type of downtime. Primary
database is up but distribution agent is going down 'after 10 attempts
to connect to replicated database'. That's the problem I think because
not only distribution agent goes in undetermined state and I have to
restart sqlagent service, but I need to go through whole process of
snapshot and applaying it to replicated db. I would like it to
accumulate transactions in distribution database and once replicated db
is up - distribute them.
I wonder if anybody can tell me how to configure distribution thread so
it does not go down after 10 unsuccessfull attempts but stays for day
or two.
Thank you, Gene.

Hi all,
I'm having a problem configuring one of my SQL servers
as a distributor. I've done it successfully on another
server, so I know that it's nothing procedural and there
must be an issue with the way the server is set up.
When I click 'finish' on the Configure Publication and
Distribution Wizard, I get the following error message:
Enterprise Manager could not configure 'ABEL' as the
distributor for 'ABEL'.
Error 20017: Cannot add the remote distributor at this time.
Make sure that the local server is configured as a Distribution
Publisher at the Distributor.
Can anyone point me in the right direction? I'm fairly new
to SQL Server, so feel free to explain things in a
condescending manner. ;-)

I am trying to "Configure Distributor" prior to setting up the publications. When I go through the wizard, at the very last step I get the following error:
******************************************************************************************
SQL Server could not configure 'serverName' as a Distributor.
------------------------------
ADDITIONAL INFORMATION:
An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)

Cannot find the principal 'sa', because it does not exist or you do not have permission.
'distribution' is not configured as a distribution database.
Changed database context to 'master'. (Microsoft SQL Server, Error: 15151)
******************************************************************************************
I have renamed the 'sa' account. Is there a place I need to change it to the new name for the distributor to work?? Thanks.

I have had a good look through the forums and have found several ideas about permissions on the DATA folder to no avail. I have also not changed the sa user it is still sa. Unfortunaley all the things I have found haven't worked. Have you got any ideas?
They would be greatfully received.

Arghh ...
I have searched all the newsgroups and applied or tried all the suggestions, with no success. I have completely uninstalled and reinstalled SQL 2005.

Hello,
I have built a system, that uses a .dll file for all SQL operations. So a program looks something like this:
using myDLL;
....
SQLDBCON mSQL = new SQLDBCON();
and here comes the rest of the program.
My question is, the dll file has all stored procedures and when you declare mSQL as shown above, then it opens a thread to the database for that user.
Is that thread properly closed when the site has finished loading?
in my .aspx page i dont have a function like mSQL.CloseDB();
and if i try to add something like this to the dll file
~SQLDBCON {
m_local_con.Close();m_local_con.dispose();
}
i get a error message says something that this is not allowed.
Just want to know if my thread in the dll file is properly closed?

The reason I had to start a new thread was that the old thread seems to be closed. There is no "Reply" button showing.
I still have the same problem. The last post asked if I was sure I was using SQLExpress.
I only have SQLEXPress and I have never had anything else. Therefore the question becomes - Why does the system seem to think I have another version?

Hi,
We have to move two of our servers in US hosting SQL Server 2000 database to different location. These servers are clustered using MSCS and uses SAN to store database data. The database on this cluster hosts publisher and distributor. The other two sites in Europe host updateable subscribers. We are using transactional replication. The downtime will be around 24 hours during which servers will be physically moved from one location to other. During this time we will keep the two subscribers running and let the changes queued on subscribers. I have listed following steps based on my limited knowledge of SQL Server. Could somebody please advise if this approach is valid and if I have missed any steps?
1. Make sure no users are accessing database
2. Backup database (In case of emergency need)
3. Stop snapshot, Log Reader, Queue Reader and Distributor Agents
4. Stop SQL Server Service and SQL Agent
5. Take OS backup
5. Shutdown the server
6. Ship the servers and OS backup to new location
7. Setup servers at new location and restore OS backup
8. Start SQL Server Service and SQL Agent
9. Start agents listed in step 3
Regards,
Nilesh

I got Server A with 30 Databases and I was asked to move 30 databases to Server B…
But server A is having 2 databases as Publication and Distribution to two different servers….. and Server A is a subscription for 6 Databases from other servers….
Once I move the databases from Server A to Server B…… what is the best way to get the Replications too…. I mean Server B should have 2 Db’s as Pub & Distr and 6 Db’s as Subscription…
Is there any way I can script it out in Server A and run the same script in Server B with some modification…. so that the Replication work…..??
I have Jobs and Maintenance plans…. Which should also move from Server A to Server B…. I know using DTS...... is there any better way..??
Please some one give me ur suggestion on this…
Thanks

Hi, I have setup a merged replication on two server. Server A contains the Publisher and the Distributor database and Server B contains Subscriber.
If the database at the Subscriber got corrupted. I am thinking maybe i can 'restore' the subscriber database by resynchronising the data from the publisher to subscriber.
But what happen if the Publisher database failed? How should one restore the publisher database and then restore the replication setup?
What will be a good backup/restore strategy for such a setup?

I have a table that was set up with a primary key - that i need to change. The problem is that the database is being replicated to a remote location, and will not allow me to remove or change the primary key on a published database.
Due to the size of the database and bandwith limitations it is not an option to re-initialise the published database.
Is there any to do this without breaking replication

Is there a way to move a SQL replicated database from one server to another without dropping the publication?
I have SQLCE setup with SQL server 2000; I want to redo the server but needs to move my replication to a temp server and then back.
The problem is that I do not want to drop my subscription and recreate it…it needs to stay the same.

We are going to implement either a replicated database or use log shipping to another database to support our reporting needs. Basically we are moving reporting over data off our transactional database.
With this in mind, I have several questions:
Are there any special configurations in terms of disks for a database in this situation?What are the recommended raid types?
Also, we currently store our data in one filegroup and indexes in another so obviously I'll want those on 2 separate physical disks other than the C:. What about the log files? Do I care where they go (on C: or another physical drive separate from C:, data filegroup drive and index filegroup drive)?
Thanks!

When I try to remove a table, it complains because it's part of apublication. I could script the publication and subscriptions suchthat they can be deleted, the table removed, and then added again.But, I not sure if this is the 'best' approach.Anyone faced this challenge before?Regards,gary

Hi All,
I have SQL server 2005 Database which is having following Replication stuff.
1. 6 merge Subscribers
2. 5 Snapshot Subscribers (Push Susbribers)
3. 3 Transactional Publisher
Due to the Performance Issue, there is need to move SQL server from the Current Server to an Higher End Server.
I want to keep all the Replication settings after movement of the Database. Can anyone tell me how to acheive this requirement?
Is there a possibility to keep the Replication settings ? Even we can have the Same System Name to the New Server.
Awaiting response...
Thanks,
Thams.

Hello All,The setting is SQL server 7, on Windows NT.If the distributor can not access the log on the publisher database ( butsubscribers are not deleted yet), will the full backup of the publisherdatabase truncate the transaction log? My guess is, it will not truncate thelog.Can any one confirm please?Thanks,Mokles

I'm a novice with replication and am in need of direction on how to restore replicated databases. Server A replicates 5 databases to server B using transactional replication. Server A also contains the distribution database. I'm perfoming PUSH replication.
The development area asked me to restore Server A with a copy of production data located on server C. After I restored the data from C to A, I noticed that server A was no longer published. Is this normal?
I re-published the 5 databases, but noticed that the Log Reader Agent has now been running for 2 hours. I'm trying to give myself a crash course in replication, but am coming up empty regarding (1) the prefered method for restoring replicated databases and (2) determining why the Log Reader Agent is taking so long.
Any suggestions?
Thanks, Dave

I have a production database which uses merge and snapshot replication. The Merge is for 3 tables. The snapshot is to update the rest of the data once daily. I use a Full recovery model and perform database backups (full, differential) and transaction log backups.
I have a database optimization plan which runs 4 times a week. This plan performs and integrity check and rebuilds the indexes. This optimization plan is growing the transaction log by about 8MB each time it is run and we are running out of space on the drive for our log files. The space is not being reused.
I saw in another post where Gail Shaw suggesting using SELECT name, log_reuse_wait_desc FROM master.sys.databases to see why the log space is not being reused. On the database in question, the above returns "REPLICATION".
A colleague tried to backup the transaction log a couple of times to truncate the log this weekend. She was going to perform a DBCC Shrinkfile command afterwards. But the truncate failed. Again looking into things it seems replication prevented the truncation.
We are looking at stopping the merge replication or even removing it to truncate the log file and then recreate the merge replication. How to handle shrinking the log file for now and then seeing if there are any checks or changes I can perform which will allow the transaction log space to be reused.

How can I list all of the Subscriptions in a CE Database that was created with the .Net System.Data.SqlServerCe.SqlCeReplication.AddSubscription method?
After I create the CE database in an sdf file, I can connect to it with SQL Servr Mgmt Studio, then see the list of Subscriptions in the Object TreeView, under "Replication"
But I can't find that Subscription list in any properties or methods of System.Data.SqlServerCe.SqlCeReplication or System.Data.SqlServerCe.SqlCeConnection
Should I be looking in RMO features like Microsoft.SqlServer.Replication??
We want to confirm that a local CE database was last synced from the expected SQL Server database by checking the Publisher property of each subscription in the CE database.
Thanks

Hi,
I have transactional replication set up on a DB and run database maintenance scripts (index defrag, update stats, etc) on this DB daily.
Will the maintenance job/scripts also be propagated to the replica (subscriber) causing these maintenance operations to be performed on the replica OR do I need to create separate jobs on the replica DB (subscriber) also? I'm guessing the latter but wanted to verify to make sure I wasn't missing something. Thanks!

I have a publisher database set up for a merge replication. This is using parameterized filter with join filters.
I also have a stored procedure that does deletes & inserts on the table where the parameterized filter is applied to aid in changing a subscriber's eligibility to receive so and so data. I have observed that running the stored procedure takes extraordinarily long and as a result, the log file grows to a size 1.5 - 2.5 times the database size.
At first I reasoned that this might because I had it set up to use precomputed partitions and changing it requires recalculating the partitions. As a test, I turned off the precomputed partitions. Didn't work. I turned on "optimize synchronization" AKA "keep_partition_changes", which normally is not available when you have precomputed partition on, and that didn't work, either.
At this point, I think I can rule out precomputed partitions being a problem here but I'm stumped now what else I should do to reduce the amount of log writes being required. We do need the parameterized filters & join tables, so that can't go.

I'm trying to get my first replication going, and I have set up a database successfully, along with merge replication, however when I attempt to create the first subscriber, I get a permissions issue, regardless of what I do. In the SQLCESA30.LOG file, I get the following entries:
