Hi,
I have SQL 2005 database mirrror enviroment with MS jdbc driver 1.1. From code, I need to get server name that current connection connect to at run time (which server that the current connection connect to: Priciple server or mirror server). Any help for that?
Thanks a lot!

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,
I was wondering what was the limitations of Sql Server 2005 standard w/ 1 calThis is the version that is given out at the launch events.We are currently developing a site, that will use Sql Databases and was wondering if the version we have now will work.Like we know for a fact that the site will recieve a decent amount of traffic. Is standard limited to certain kind of sites and so forth?Thanks,Cedric

View 1 Replies View RelatedI posted a question yesterday (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1717961&SiteID=1) that was very specific concerning problems running WCF inside SQL. I guess its quite unlikely that anyone will have had the same problem so I'd like to ask a more general question.
What is it that is different about running a .Net method contained in an UNSAFE assembly inside SQL than running it from a console application or mstest?
One difference is the identity (typically NT Authority/System) but I've discounted that by temporarily running SQLSvr under my interaction administrator account.
One gets a lot of warnings when importing system assemblies into SQL about them not being tested but is there much different about the execution environment.
I guess one difference is the assembly loading subsystem - not fusion in SQL's case. One can't access assemblies in the GAC or in probing paths. Any other differences that might give me a clue as to why I can't get my WCF channel to work?
Any help gratefully received,
David.
I have SQL Server 7.0 installed on a shared disk resource in a cluster group. I am wanting to use Outlook 98 ( 97 or 2000 will also be fine if it matters) for the mail profile. Do I install Outlook on the local server drive and reference that in SQL Mail or do I install Outlook on the shared resource drive and reference it there? Any suggestions would be greatly appreciated.
Thanks,

Hi all, I think I have the right group, if I don't then I doapologize.My problem is that I'm trying to run a SQL script within a VBEnvironment. The actual program is WISE Installer, but I'm sure thatthe same problem arise within VB because we have also wrote an appthat is meant to run SQL scripts (But falls over the same). Basically,there are some SQL keywords that are Query Analyser only.. ie: GODoes anyone know of a list of Query only statements? The code belowfails, but since it's not as verbose as Query, all I'm getting is'INCORRECT SYNTAX NEAR THE KEYWORD "PROCEDURE". Here's what's aroundit:^^^^^^^^^^^^^^^^^^ More stuff aboveSET ANSI_NULLS OFFCREATE PROCEDURE ASP_OutstandingStaffingRequirements@stDate as datetime, @enDate as datetime, @locId as integer,@gradeCount as IntegerASCreate Table #glb_outshifts^^^^^^^^^^^^^^^^^^^ More stuff below.Any help would be great as I'm banging my head against the wall here.BTW.. I don't actually know what the SQL script does, I'm just tryingto package together a deployment solution.Many Many Thanks. Regards Mark (SQL GURU.. LOL)
View 2 Replies View RelatedIm about to start a project that will be hosted by a third party web host. What is a common way to backup your database and have the backup saved ? The data may end up being several 100 MB of user settings, text etc (blog type stuff). If the DB gets to be several 100MB, then does making a backup and ftping it offsite sound reasonable ? Does ftp bandwidth usually count against your overall bandwidth usage ?

I have been made the point person for our migration to SQL2005. We are a law firm with approximately 750 users. The first SQL environment we will be upgrading is our document management system (DMS). This is an intensive SQL product. After this migration we will more of to our finical system, records system and then all home grown databases.
What we would like to do is consolidate servers and scale out the new SQL environment to a farm. After some initial research it does not look like we will be able to scale out, since the data in the DMS is always changing.
Does anyone have some advice or guidance on what direction we should be looking? I have done tons a online searches and can find out information on everything to do with SQL, except this.
Thanks in advance,

I need to upgrade a solution from SQL Express Advanced to Workgroup Edition because of the 4GB size limit. I'm planning on deploying the solution in an secure web enviroment were only authenticated users will be able to access the database. The actual username's and passwords would be stored in an Express database. Therefore since only named users would be accessing the database server web app, can I use the CAL license model??
View 1 Replies View RelatedI used 3 seperate web.config files - one for Development seerver, one for Certification server, and one for Production server. The only difference between these three is the within the <connectionStrings> tags.
For Example:
<connectionStrings><add name="strConn" connectionString="server=xxx;uid=xxxx;pwd=xxxxx;database=yyy;"/></connectionStrings>
Within Development the connectionString points to the Development SQL server, Cert to cert SQL, and Prod to Prod SQL. I do not have permissions to copy new Web.Config files into Cert or Prod, so when I have a change within my web.config I have to have another group manually add these files.
Is there a way to identify the domain I am curernt within and use a specific set of connections string within the web.config based off this information. If so, can anyone post an example of how to do this...
hi,
i have installed SQLEXPRESS (SQL Server 9.0.3042) on my windows ultimate laptop. of late am facing this issue of database. this database is from SQl 7.0 Desktop edition(the one that i use in my office machine with Xp SP2). As such it works fine in SQL 2000 server after attachment (for test).
i have run SQLEXPRESS as administrator to make/attach new database. i can attach the database easily and can even view tables and other stuffs inside database in administrator mode. the issue pops up when i run SQLEXPRESS in normal mode. when i try to open and view the same DB's content, error pops up stating
"The database XXX is not accessible. (Micorosoft.sqlserver.express.objectExplorer)"
i cannot access this DB via VB 6 form as it dosnt show up at all in database list when tried to connect via ADODC.
i want to make this DB accessibility as normal operation, not previliged only to administrator as application run on normal mode only.
the issue dosnt arise when i locally make a new database as it can be accessed when run in normal mode also. why does this happen to database that is attached and not to ones locally made.
pls guide me as i usually do my works at home and making whole database again will surely take lots of pain. why not it just attach then start working, not asking for preveliged mode.
thanks in adv

Hi all,
I feel happy to post my first thread at dbforums.com, and I think it's the community of DB professionals.
my question is:
I have two servers in my organization, one of them is running an SQL server database. Is there any way to make the second server a mirror of the first one and to make it runs automatically as the main server when the first server is down?
Thanks for replying soon.

Hi folks. I'm trying to clear up some licensing confusion I"ve come across. First, if I use MIRROR on SS SE I am limited to a single REDO thread and Sycn mode. I see that on the Web. Will the singel REDO thread hurt the ability for the Secondary to keep up? Any one done any tests?
My confusion comes from a document that came across my desk a long time ago that showed that if you use MIRROR on SQL Server SE you are limited to 4 processors for the entire cluster. So if you wanted a balanced failover you would have to have two 2-ways in essence. Is this true? Is it not longer true? I can't seem to find any mention of this....did someone give me bad advice? Help! Thanks.

If your principal fails and your mirror assumes the main role and it is in Full recovery mode (which it has to be in Standard edition), then the log files will grow and grow until a transaction backup and shrink is executed.
I have maintenance plans running daily (and hourly for transaction log backup/shrink) on my principal, but nothing on my mirror.
Do I need to set up the same maintenance plans on my mirror server???
Thanks

Hi Everyone;
I have a SQL Server 2005 DB server (SRV1) and a mirror DB server (SRV2) without witness server. I saw that there is a "Failover" button on Mirror window of SRV1. When click it servers changes roles.
My question is that: If my mirrored DB server crashs and I can not open windows or if I lost all data on SRV1, how can I failover from only mirror DB (SRV2)?
Thanks in advance.

I need to migrate my SQL server Mirror Database to a new server. my current setup is as below
1. server A principal (192.168.1.100)
2. server B Mirror   (192.168.1.200)
Now i have a new server (Server C) to replace server B as below
1. server A principal (192.168.1.100)
2. server C Mirror   (192.168.1.300)
My question is how to migrate mirror db to new server without any affect or downtime on principal server.
note: SQL SERVER 2008R2 EE(64BIT), Win2008R2 EE 64bit.
Hi all,
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?
Many thanks in advance...
Hello,
I hope this is in the right forum, I'm new to MSDN. I'm also not an expert in SQL, so please bear with me as I was unable to find an answer by searching the archives.
We have a single SQL 2005 Standard installation with 30 user CALs on a Server2003R2 box. We have another Server 2003 box in a remote but connected location that we previously used for backup replication. What we'd like to do is use some of the replication features in SQL 2005 to replicate the data over every night to the other box, onto which we would install another copy of SQL 2005. This would not be a server accessed by clients, but simply a "live backup", that in the event of a catastrophic failure, could be manually set up to operate as a SQL server in place of the failed primary server. I don't need any kind of automatic "failover", just the ability to replicate the data over to the other system so I have two SQL Servers that synchronize from one to the other overnight.
I was told that I wouldn't need to buy the user CALs again, that the 30 user cals would translate over if the primary server fails and has to be replaced by the cloned server. But what do I buy for the SQL server itself? A boxed version is a bit pricy and comes with 5 CALs which apparently I wouldn't need. Then I noticed that on softwaremedia.com the open license version, which can be bought a la carte, lists a requirement of buying at least 5 cals or a processor license. What exactly do I need to do this, and how can I get it for the least amount of further spending?
Thanks!
Hello,
the Mirror Server is not connected to the Witness Server.
Mirror Server and Wtiness Server are instances on one server.
I get this error:
"
2007-06-28 17:08:12.77 spid23s The server instance Witness rejected configure request; read its error log file for more information. The reason 1451, and state 3, can be of use for diagnostics by Microsoft. This is a transient error hence retrying the request is likely to succeed. Correct the cause if any and retry."
In the SQL Profiler for the Witness Server I get "An error occurred while receiving data" Error 64.
In the witness server logs is nothing depending on this.
The connection between the witness and principal and the mirror and principal are all right. I have created User logins with certificates on the same way on all instances.
What can I do?

Hello All,
I've tried to replicated exactly what it says in the online documentation. At the end of the post are the SQL statements issued.
1. Enable encrypted outbound connections on the primary server
2. Enable encrypted outbound connections on the mirror server
3. Enable encrypted outbound connections on the witness server
4. Enable encrypted inbound connections on the primary server
5. Enable encrypted inbound connections on the mirror server
6. Enable encrypted inbound connections on the witness server
7. Set mirror''s partner to the primary
8. Set primary''s partner the mirror
9. Set principal€™s witness.
Every step run''s normally,but why can''t auto failover.

I have created a Endpoint with "Mirroring Server" on the mirroring instance. Due to the keyword server i am not able to drop the endpoint now.
Also am not able to configure a mirror in a windows workgroup also( the two systems principal and mirror are under same network ). I have followed many ways as per msdn articles and other blogs.
I am not able to connect to the mirror server.Â
I have tried giving the ip addr and the port no, also the computer name:port no, computername.local:port no etc. Both the systems are running on sql server 2008 only
I always get the error as Connection cannot be established to the destination.
(I have also enabled the ports in firewall by creating inbound and outbound rules)
The issue probably lies in NAMING server address i guess.
Hi everybody,
I have a mirroring set up for around 30 databases in a 64 bit - 2 powerfull servers scenario - wih latest sp2 + hotfix. Mirroring works perfectly most of the times but when the principal is getting busy during the busy period of the day all of a sudden the processor on the mirror jumps to 100% and stays there for a long time - there are no live databases on the mirror server - all the databases are in mirrored mode. The principal server processor is less than 5% all the time. The network load between the principal and the mirror is also in normal limits. The principal server is dedicated to SQL but the mirror has other things too but the other processes use up maximum 15-20% of the CPU and when I stop SQL Server in one of those moments when the CPU jumps to 100% everything comes back to normal so it's clear that the issue is SQL on the mirror.
Any ideas would be greatly appreciated.
Thanks,
Stefan
I have do some benchmark test between the "Principle", "Mirror" and "Witness", things seems normal, the System usage (CPU, Disk Read/Write) on the "Witness" is very small and the CPU usage on Principle and Mirror is similar, However....
For the "Disk Write Bytes/sec", the usage on Principle is 200,000 and the Mirror is 1,500,000, the mirror server is talking about x7 times Disk Write Bytes/sec on the Mirror.
I cannot think of any reason why the Disk Write Bytes /sec is so much higher than the Principle, can somebody help me?
Hi guys, right now I am having insufficient hard disc space at the secondary server (Mirror side) due to the large db that I have. Therefore, I get a new HDD on the server (Assuming located at drive G) and would like to shift the current mirroring db to that new drive. Is it possible for me to do that ? Hope able to get any suggestion from here ASAP. Thanks.

II use the mirroring wizard to config all these three servers(windows authorization is used), the error logs in primary server and mirror server are showed as below
a) On primary server:
Error: 1474, Severity: 16, State: 1
Database mirroring connection error 4 'An error occurred while receiving data: '10054(An existing connection was forcibly closed by the remote host.)'.' for 'TCP://mymirror.mydomain:5022'
b) On mirror server:
Database Mirroring login attempt by user 'NT AUTHORITYANONYMOUS LOGON.' failed with error: 'Connection handshake failed. The login 'NT AUTHORITYANONYMOUS LOGON' does not have CONNECT permission on the endpoint. State 84.'.
It states I do NOT have permission on this endpoint, but actually, I grant the permission to the endpoint on both primary and mirror server using command
GRANT CONNECT ON ENDPOINT::Mirroring TO [mydomainmyuser];
Also, I followed the article http://msdn2.microsoft.com/en-us/library/ms189127.aspx ,no firewall issue, the endpoint is created and started by checking sys.database_mirroring_endpoints
Hope someone can help me resolve this issue... Thank you very much..
Hi All
Hope someone can help.
I have an urgent requirement to setup a backup SQL server 2000. This will run as a mirror of the live SQL server 2000 which processes about 5000+ statements per minute. I will need to keep the mirror server as close to the live as possible, so if we need to take down the live server we can switch users to the backup server (it’s ok I can do this in code – client side.) and I may also be reporting from this server to take some of the strain from the live server (if that’s wise – not sure yet).
Can someone please point me in the right direction? What other software (apart from MS SQL server 2000) will I need?
What sort of link do I need between both servers? (note: I don't want to do this link using triggers for each table if possible)
Are there any pitfalls to look out for (i.e. I seem to remember something about auto id fields in tables but this was a long time ago so I could be wrong).
Please note I am a programmer with a lot of experience, but I don’t know that much about setting up SQL servers (well I can install one locally on my dev machine, but that’s really as far as I go) but I am willing to learn and investigate anything, so just giving me sites that I can look at will be enough.
Thank you in advance.

I was contacted by the SAN team to test backup/restore of larger databases using a split-mirror backup (BCV) or clone that is taken from production db server and copied to another sql box. They want to use this process once a week. I see the mounted drives with the data/log files. All looks good. Initially I attempted to attach the databases and received (Unable to open the physical file db.mdf Operating System Error 5 Access is denied). I manually granting SQLServerMSSQLUser$<computer_name>$<instance_name> on all of the physical files 20 total. That worked.
Since this will be weekly, the SAN team performed the copy again and now none of the databases can communicate with the newly copied files. NTFS permissions need to be set again. I'm getting (Operating System error 21: the device is not ready). Is there something that I'm missing in this process how the vendor BCV clones the data and SQL communicates with the copied files as I was thinking it would be more automated process?
