I am new to Microsoft SQL Server 2005 and i would like to make use of its database mirroring feature.
My question though is: is database mirroring supported by the JDBC driver and if so how would you implement/code a connection to principal and mirror servers i.e. how would i implement a client - redirect in case of failures.
Any help will be greatly appreciated.
Hi All,
I get a general question about the feacture "Database Mirroring". Is it support by SQL Server Standard. Edition without SP1?? Of i still need to upgrade the server from SQL Server 2005 to SQL Server 2005 with SP1?
Another question: are there any problem if the one machine(server) has installed SQL server 2005 Standard edition and the other with "Developer Editon".
I hope some one can answer my question. Thanks anyway!
Regards,
Pat
I am trying to configure distributed transaction and XA support using Microsoft SQL Server 2005 JDBC Driver. I have coppied SQLJDBC_XA.dll from XA directory and placed in my sql server binn directory and trying to run the script xa_install.sql from binn directory with command as below :
C:Program FilesMicrosoft SQL Server80ToolsBinn>
osql -U sa -n -P admin -S localhost -i C:JavaLibrariesMS SQL Driversqljdbc_1.2enuxa xa_install.sql
But I am getting error saying :
[DBNETLIB]SQL Server does not exist or access denied.
[DBNETLIB]ConnectionOpen (Connect()).
when I replaced local host with the machine name it gives error :
[Shared Memory]SQL Server does not exist or access denied.
[Shared Memory]ConnectionOpen (Connect()).
where in I am able to test connection from Websphere using the same connection.
Please help some one ....... I am in URGENT need.... I need to enable XA suport for my application to run........

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?
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....

Hi all,
We've just stumbled on a 1.0 version incompatibility with the JDBC specs.
Problem: A table with SMALLINT column. According to JDBC specs version 3.0
(p.B-179) and 4.0 (p.221)), the value should be converted to Integer type.
Unfortunatelly we get a Short object :(
Now, I remember, this case was also affecting old JSQLConnect driver from
DataDirect. Could that problem sneak to new MS driver too?
Please let me know any resolution to this problem if exists.
The issue has not been fixed in CTP 1.1 version. Any ideas if it can be fixed??
Cheers,
Piotr

I've just started hosting my newly created Microsoft Visual Web Developer 2005 Express Edition web site. Unfortunately the Login group membership functions will not function correctly. Having contacted the web service hosting provider, They replied: "We do not support SQL express2005. The only way to use the extra functions of ASP.NET2 such as group membership is if it is using an SQL 2000 database to connect to. "
Is it possible to design web sites with Microsoft Visual Web Developer 2005 Express Edition that store membership details on an SQL 2000 database?
I've just paid £88 approx. $140 for a years subscription, have I chosen the wrong web service hosting provider?
Should I have designed the web site with a better web site design software tool that also makes designing membership login functionality easy, just as Microsoft Visual Web developer 2005 express edition?
Look forward to all comments?

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?

I need to be able to connect(JDBC?) to my MS OLAP database from my Web based Java application. Can this be done? if so how.
Your comments would be greatly appreciated
When I issue this command:
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?
Hi,
View 6 Replies View RelatedHi,
I am working with the followings: jdk5 in eclipse3.3 and Microsoft sql server. For the jdbc application, i used to connect the database with the following code:
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
con=DriverManager.getConnection("jdbc:microsoftqlserver://NODE1:1433","sa"," ");
The above code woks fine and I able to connect the database.
Here is my problem: The above code only connect the master database. But I want to connect the user defined databse(that is., other than master database).
Can anyone tell me the solution to solve the issue.
Looking forward to your reply,

Please do inform me about the SQL server database capacity of handing the data.
Well, I€™m a designing Data warehouse database on SQL server 2005 my first time load of data is 9 million records for 30 years of period, and future growth of data would be almost 20 million for the up coming 10 years.
Will this database would be able to handle that much of data.
Thank you
I've got an import app written in Java. One table I'm importing from contains 22 million records. When I run the app in a 2000 environment, I have my max heap set at 512, and the table gets imported. When I run in a 2005 environment, I have to change the max heap to 1152 or it will error out with a similiar error:
com.microsoft.sqlserver.jdbc.SQLServerException: The system is out of memory. Use server side cursors for large result sets:Java heap space. Result set size:854,269,999. JVM total memory size:1,065,484,288. (<--this is with max heap at 1024)
what is the difference between the 2000 and 2005 JDBC that I have to set max heap in one and not the other?
Hello ,
I get this error (connection closed) in web applications, whenever SQL Server database Service is restarted. When I run the application again, the error disappears. Granted that there are lots of users and Database gets restarted every night is not helping.
Is there any setting in the JDBC driver properties, where I can tell it to open a closed connection (like a retry count), rather than fail the first time and work the second time.
We use
1. SQL SERVER 2005 SP2,
2. Websphere Protal Server 5.1
3. SQL SERVER 2005 JDBC driver 1.1(com.microsoft.sqlserver.jdbc.SQLServerConnectionPoolDataSource.)
I am wondering if connection pool driver is causing this problem. I do not care about connection pooling, but Websphere doen not seem to like any other JDBC Driver. I don't mind switching to another driver as the last option.
Error is :

I am trying to connect to an SQL database with a Java program compiled in NetBeans IDE. I have copied the proper .dll in the auth folder to the same folder as the .jar file required. I have tried a lot of things for a lot of hours, and am still coming up with the message "Driver is not configured for integrated security and "could not load the xxxxx.dll
Has anyone come up with a solution or a workaround to this problem. Please help. I have read the documentation until I am blue in the face. Please only respond if you have a 64 bit machine.
Thanks, Frank
I have to build a coherent argument for why we should fix the application to run at compt level 90 instead of just leaving it at 80.
Looking at . . .
Differences Between Lower Compatibility Levels and Level 90
http://msdn2.microsoft.com/en-us/library/ms178653.aspx
. . . I can't find anything further that tells my why it is in our best interest to do so other than 'Microsoft won't help you until you do'.
Anyone have any good bullet points on this?
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.
Any idea what might be going on here?
Thanks in advance.
I am looking in to using Microsoft Clustering supported in NT Server Enterprise to provide failover support for 2 database servers running SQL Server 7. I was wondering if anyone had any experience with it--good or bad. I read the white paper and it sounds good, but I'd like to get some real
world application experience.
Thanks for any info.

I have a database that tracks players for children's sports clubs. I haveincluded representative DDL for this database at the end of this post.A single instance of this database supports multiple clubs. I would like toadd support for letting each club define and store custom information abouttheir players. Basically, allows the clubs to define custom attributes forplayers (e.g. "height", "weight", "favourite sweet").A few constraints:1. Any attributes defined is "private" to the defining club. Other clubsaren't aware of it although they may define custom attributes of their ownwith the same name and type. [Perhaps there is a way to share definitions ofidentical attributes?]2. A club doesn't have to define any custom attributes.Has anyone done anything similar?. Any ideas on how it might be done?Kunle=================== BEGIN DDL ===================CREATE TABLE FootballClub (Club_ID int IDENTITY,Name char(80) NOT NULL,Area char(4) NOT NULL,League char(4) NOT NULL,City char(30) NOT NULL,PRIMARY KEY (Club_ID))goexec sp_primarykey FootballClub,Club_IDgoCREATE TABLE Player (Player_ID int IDENTITY,First_Name char(30) NOT NULL,Initials char(30) NULL,Last_Name char(30) NOT NULL,Date_Of_Birth datetime NOT NULL,Position char(4) NULL,Club_ID int NULL,PRIMARY KEY (Player_ID),FOREIGN KEY (Club_ID)REFERENCES FootballClub)goexec sp_primarykey Player,Player_IDgoCREATE TABLE UserAccount (User_ID int IDENTITY,Club_ID int NOT NULL,FullName char(80) NOT NULL,Logon char(20) NOT NULL,PWD_Hash char(60) NOT NULL,PRIMARY KEY (User_ID, Club_ID),FOREIGN KEY (Club_ID)REFERENCES FootballClub)goexec sp_primarykey UserAccount,User_ID,Club_IDgoexec sp_foreignkey Player, FootballClub,Club_IDgoexec sp_foreignkey UserAccount, FootballClub,Club_IDgo=================== END DDL ===================

Hi All,
Does anybody know the OS requirements for Database Mirroring? I checked BOL and Google but couldn't find any info on that.
Thanks.
Hi All,
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.
Hi All,
Couple of questions about database mirroing.
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?
Thanks.
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.??
thanks
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....
