Database Mirroring Monitor Not Working For One Database
Apr 2, 2008
I set up a new mirror server. Everything is good except that the Database Mirroring Monitor is not working for one of the databases. In the monitor the principal data is showing up as blank
If I look at dbm_monitor_data on the principal most of the data columns (e.g. Send_queue_size) are null where as they have data for the other databases.
Both servers are SQL Server 9.0.2047 Enterprise Edition.
I've some trouble with monitoring a database mirroring session. I am testing a lot configuration possiblities, and i use the database mirroring monitor to view the mirroring states.
But in some (most) of my configurations, i only get following informations in the database mirroring monitor:
Oldest unsend transaction, Unrestored Log, Current Restore rate and the Witness Adress. I am working in High safety mode with automatic failover.
Question 1: What are the reasons that all the other indicators (Unsend log, Current send rate, Mirror commit overhead) are not shown?
Question 2: In the moment, i am using certificates for the mirroring communication. I think, my client (who the database mirroring monitor is running) connects with the usual windows authentication to the server and only selects from sys.database_mirroring or something else. So there is no need to create inbound certificates on the partners for the client who is connecting with the mirroring monitor?
We have recently set up two SQL Server 2005 Standard Edition serverswith database mirroring. The mirrors function and fail over without aproblem, but the Database Mirroring Monitor Job fails every time withthe following error message:Incorrect syntax near '.'. [SQLSTATE 42000] (Error 102) Incorrectsyntax near the keyword 'with'. If this statement is a common tableexpression or an xmlnamespaces clause, the previous statement must beterminated with a semicolon. [SQLSTATE 42000] (Error 319). The stepfailed.Both SQL Servers are running SP2 with the latest patches.Can anyone help with the resolutionto this this issue?Thank you!Bosko
I have just finished configuring my first test mirrored environment (High safety mode). I setup the database engine service accounts on each of the servers with domainuser. I inherited a production mirrored environment set up by someone else. On the production servers the database engine service account is NT Authorityuser a local account. I am trying to practice installing Windows updates within a mirrored environment and I not sure how to proceed when the service account is NT Authority user account. should I change the service account to a domainuser?
ALTER DATABASE foo set PARTNER = 'TCP://10.3.3.1:1234' I get this error message:
The database is being closed before database mirroring is fully initialized. The ALTER DATABASE command failed. What does that mean, and how do I fix it?
So I successfully got the mirroring to run and now I'd like to see what's going on between the two servers ( i'm not using a witness). I launch the Database Mirroring Monitor and its showing the two servers but when I go to the history column I'm not seeing any data movement. I've done a an update on a db with 1500 rows so I was expecting to see this show up.
Also, is there anyway to query the database thats acting as the mirrored db?
Using SQL Server 2008, we would like propose mirroring between two servers of a critical database. Since we initiate, may require to clarify on its purpose and also required changes from application end.Any changes required from OS Level? (I believe both servers IP or Host name should be added in host entries. Mirroring ports should be allowed/open including Principal and mirror server IP Addresses): Windows Team.Any changes required from Application? (Instance name, authentication: user name and its password should be added in web config files): Application Team.Any changes required from Network Team?Also for mirroring both the principal and mirror servers should be with same version, does it only mean SQL Server 2008 versions are enough or does it also mean to say build numbers 10.00.4000 should also be same.URL....
Not sure if this question makes sense, but is it necessary to purge old data in msdb tables used by the db mirroring monitor job?
I'm just wondering if an insert into the data table every minute of the day would still be needed a month from now. I'm thinking this data would be useful for the purpose of "alerts" and to have access to its recent history, but other than that, is it recommended (or necessary)? Would these records keep accumulating until manually purged?
I am looking for a way to monitor the space remaining inside of a database and to receive an e-mail alert when that space gets below a certain threshold.
What I want to do is schedule a job to run every hour or so and check to see if available space in my databases is below about 300 megs. If it is I would then like to be sent an e-mail to my cell phone. I have jobs like this already running on my Oracle databases but am not sure of which tables to query for this in the SQL Server environment.
Does anyone know which table(s) would need to be queried to retrieve this info or, better yet, have a script which already written?
Thanks in Advance!

Greetings All, I was hoping that some of you might be aware of anyfree scripts that were written explicitly for the purpose ofmonitoring a SQL Server database. I want to be able to determineup/down events, Error Log updates, Long running Transactions,Deadlocks, etc. My plan is to use a central SQL Server database as arepository that will query (via t-sql) the target SQL Server boxes forthe events listed above. If one of the events falls outside of adefined range I will use xp_sendmail to alert me via my pager. I havebeen looking at third party tools like BMC Patrol, Quest Foglight, andEmbarcadero Performance Center and although they are very nice theyare also very EXPENSIVE. I am looing for a cheap solution. Any helpwould be greatly appreciated.Louis
I need to monitor my database growth, as few of databases are growing rapidly. My client wants the growth list of my databases. have report of database growth of specific databases, at least of one month.
I've been running SQL 2005 Enterprise SP1 for some time. After installing SP2, I miss the "Database Mirror Monitor"-Feature. Where is it? Did MS kill the feature?
Currently there are various teams accessing the database. For costing reasons, we need to track usage.Is there an efficient way to monitor User access to the database.Can we track which user has executed which query(SELECT,insert etc),the login time and such parammeters?
I have read on the web that high protection mode not recommended, except in the event of replacing the existing witness server. But I can't find the reason why anywhere. Can anybody explain? Thanks.
1. Once the mirroring is setup is it possible to switch between high-protection and high-performance modes? If it is will I have to stop the mirroring, switch the modes and then restart it again?
2. Let's say the principal server went down and I manually failed over to the mirror server. Mirror server runs as a new principal server for a couple of days and then I bring the original principal server back up. What needs to be done in order to bring transactions on the principal server up to date?
for a database mirroring , which stretergy is good. Creating with witness server or without it.?
I am firsttime doing this , so i am posting it to the forum..
and also if we are creating the database mirroring with witness server for automatic failover , will the witness server need the same amount of harddisk space like the pricipal or mirror server.??
we want to migrate our production server , without taking the database down.so what we did was , we mirrored the databases from production to one of our development servers and we took the prodcution server for uprgrade.
so today we are moving back (mirroring) all the databases from that development server to our new production server.
my question is , when i move
productionserver_old(principal server) - having the script for principal server
development server(mirror server---->principalserver)) - having the script for mirror server , which is now acting as principal server
new production server(mirror server) - having the script for mirror server. will become principal server , once i moved all the databases
now while mirroring between the developement server and the new production server, i have to run the scripts for the mirror server only.
so both the servers are havign the mirror script now...
is that a problem, or any other way i can handle this....
Does anybody know any good Tutorials for Database Mirroring (Automatic Failover) or Manual Sync with Mirror Server. I tried some sites online, but doesn't have detailed steps.. pls.help as i need to sync data with One of my Mirror using Sql Server 2005.
I have some questions about database mirroring. we have almost 40 databases in one server. Can I set up the database mirroring for all the databases. Is it going to any affect on performance. we have already setup the mirroring on almost 30 databases, and I need to set up for the rest of 10. please some body could help on this. Thank you.
Hi, i'm a novice of sql server and I have a problem. I have to reply a server in which there are database that are managed with sql server 2000 sp3; what I must make in order to set up the mirroring between the database of the two server so that the data are always aligned ?

Can we have database mirroring for two databases. Like i have an application where in the db used are two, namely DB1 and DB2, DB1 is used in the connection string and with the help of DB1 the tables and sps of DB2 are handled.
in this case can i go ahead with database mirroring. Please comment and give the idea or link on the same.
We have our SQL Server 2005 hosted at a datacenter and have only SS Management Studio access (no term serv, no event log, etc.). Also, our hosting company has disabled the Database Mail feature. We have over 60 jobs running on a minute/hourly/daily basis that are critical for our business. It is super important for us to know if and when a job failed.
Given this scenario, how do you suggest we implement monitoring/notification of failed jobs?
