Server Network Address on Clustered Instance

Hi,

I am looking to configure database mirroring and as part of this need to specify the server network address. The primary instance is on a 2 node cluster and the mirror data base is on a separate instance on a standalone server. When creating the server network address on the clustered instance should i specify the hostname\IP address of the SQL cluster and if so do I need to do this on both nodes in the cluster?

Thanks

CareFor hospital is one of the popular hospitals in Scotland with branches all over the world. The
hospital is known for its dedicated staff and high quality services. It has a number of specialized
departments, such as Cardiology, Hematology, Nephrology, and Oncology, each equipped with
experienced doctors. The hospital provides various facilities, such as CT scan, Ultrasound, and Xray.
New patients need to register themselves first and pay a fee prior to the doctor's appointment.
If the doctor prescribes a test, the patient needs to pay the fee of the test before the test.
Currently, the hospital management maintains details of the patients, doctors, and departments
manually. The details of the patients are stored in the Patient file and consist of name and ID of
the patient, name and code of the department, fees, and name of the doctor the patient wishes to
visit. Similarly, the details of the doctors are stored in the Doctors file. These details consist of the
doctor's name, ID, and salary, department name and ID, name of the department head, and the
doctor's prescribed fees to be charged from the patients. In addition, the details of the
departments are stored in the Department file and consist of department name and ID, associated
doctor's names and IDs, and name of the department head.
Recently, the hospital has started a free health check-up camp on the weekends. This has led to a
tremendous increase in the number of patients visiting the hospital. Consequently, it has become
very difficult for the management to maintain the patient records manually. Therefore, the
management has decided to use a hospital management system to maintain the records of the
patients, doctors, and departments online. It has also approached HighTech Inc. for developing
the hospital management application.
At HighTech Inc., a team of developers have been assigned the task of creating the required
application. Jim Houston, being the project manager, analyzes the project requirements and
identifies various components required to create the desired application. Being the database
developer in the team, you have been assigned the task of analyzing the application and creating
the required databases and tables.
You need to analyze the various files in the given scenario and perform the following tasks:
1. Identify the entities that may cause data redundancy. Justify your answer. [5 Marks]
2. Identify the problems that may arise due to data redundancy in the given scenario. Justify your
answer. [5 Marks]

Hi  Support,

I am trying to mirroring a database in sql server. I created a database and took a backup of it and restored on the another instance(i am using same server but with different instances). But after doing all operations and click on start mirroring, then it showing following error.

The server network address "TCP://indserver.xxxx.local:5022" can not be reached or does not exist. Check the network address name and reissue the command. (Microsoft SQL Server, Error: 1418)

I followed mirroring steps in this "http://www.codeproject.com/Articles/31325/Step-by-Step-SQL-Mirroring-the-ASPState-Database" Here it says, create an user on both principal and mirror server with the same credentials in STEP 3.So please provide me solution for above error.

Hi,

I have installed 2 SQL servers [SQL01 & SQL02] with failover clustering and have enabled alwayson feature.

Issue is I'm unable to connect to a database which is part of high availability group after stopping SQL service on server SQL01,

But when I shutdown SQL01 server completely, I'm able to connect to the database, does SQL always on feature works only when  the server is down or will it work even when the service is down?

please help me in troubleshooting the issue.

Regards,

Nandish N M

Dear Friends,

I am trying to configure mirroring between two servers without witness server. Both servers have configured default instance

(MSSQLSERVER). I am configuring the mirroring settings but when clicking to start its giving me this one error:

================================================

TITLE: Database Properties
------------------------------
An error occurred while starting mirroring.

I can see this error in event viewer window as follow:

Database mirroring connection error 4 'An error occurred while receiving data: '10054(An existing connection was forcibly closed by the remote host.)'.' for 'TCP://MIRROR.corp.aaj.com:5022'.

From principle: If connecting with server (mirror) without instance name then its connecting but if mentioning instance name like mirror\MSSQLSERVER then its not connecting.

Hello,

I configured database mirroring and it's working properly.  Both servers are running sql 2005 enterprise w/SP1.  I also configured snapshots on the mirror server so I can run reporting service on them.  My problem is that database names are hardcoded on views and stored procedures.  Is there a way to workaround this?  I don't want to rewrite all my reports and stored procedures.  Thanks.

Found a regedit object to set in management_sql_connection_string     failover partner= server

I used the syntax   failover partnet = server.xxx.xxx for fqdn on 2 publishing servers

I am getting the error  Failed t generate publishing metadata. Reason "Keyword not supported: "failover partnet"

I got this from a Microsoft doc 

Is the syntax wrong, do I need quotes around the server name

Any hep is appreciated.
