Pointing Server Name / Instance Name At AG Listener?
Jul 3, 2015
I've started working at an organization that has a sql 2005 cluster with a named instances on it, lets call it Instance1. What they done is to create a dns alias for servername that is the same as the instance name, so when you connect to the sql server you connect "Instance1Instance1".
We want to move to SQL 2014 cluster with AlwaysOn Availability Groups doing the HA/DR, the question is if I create a listener name called "Listener1" is there a way to using DNS or anything else to point "Instance1Instance1" to "Listener1"
In our environment applications are using a DNS name which points to the physical server ip address. Now we are planning to move to 2014. We are planning to have servers in different subnets so we will be having two ip adresses for listener. How we can point the DNS to the listener ips? If failover happens can the DNS point to the exact ip address of the listener where it's primary node?
When I setup my listener: ListenerA...Do I need to use the instance name in it?
ListenerAInstance01 or ListenerAInstance02 depending on which SQLNode is the "active" availability group?
Am I better off to use the same instance name for both nodes, since my goal is to have all databases on both instances in the same availability group and sync'd? When SQLNode1 migrates over to SQLNode2 I will need to update the instance name in my connection string on the listener from ListenerAInstance01 to Instance02? When I connect with SSMS do I just use: ListenerAInstance01 (or 02)?
datasource jdbc in UAT Server has been modified to use ms sql driver & point to the UAT sql server . I Really not understand what is exactly meaning of modified and pointing (but i know theory any application need to get access that should point to server )or otherwords we say application is pointig to database, to point one server to other what we do get that . could any one give detail idea really i am missing some basics drivers and application pointing . may i know any book or link to study more about this kind of sutuation
I have a .ADP application (access 2000 front end, SQL Server 2000 back end) I basically want to create a new .ADP file and point it to a different SQL Server 2000 Database.
I've copied the current SQL Server DB and recreated it. Same for the .ADP file, but it is currently pointing to the old Db, where do I go to have it point to the new SQL Server DB?
How to "CREATE credentials pointing to SQL SERVER logins" and "creating proxys for SQL server agent pointing to SQL SERVER login.
As The SQL server login does not display in the CHECK NAMES list when we are trying to select the identity but All the other Windows logins display correctly in this list .
So using the SQLserver login fails to run a SQL server Job (which uses the credentials and proxies pionting to SQL server logins)
The box I am trying to connect to is running two instances of SQL Server. There is a SQL Server 2005 instance which is the default. There is a SQL Server 2000 instance which is named 'SQLSERVER'. I can connect to the SQL Server 2000 instance no problem:<add key="ConnectionString" value="server=MYPCSQLSERVER;database=mydatabase;user id=****;password=****" /> However, I am having trouble connecting to the Default SQL Server 2005 instance. I have tried: <add key="ConnectionString" value="server=MYPC;database=mydatabase;user id=****;password=****" /> but it doesn't work. I have tried explicitly setting SQL Server 2005 to use port 1434 (as SQL Server 2000 is running on port 1433), and then used: <add key="ConnectionString" value="server=MYPC,1434;database=mydatabase;user id=****;password=****" /> but this doesn't work either.
Am I mssing something here? Any help much appreciated Thanks...
I am trying to build out an AlwaysOn AG with 2 nodes each in a different subnet (in AWS if that matters), windows 2012r2 / SQL 2014 RTM
I created a AG Listener with 2 ip address, 1 for each subnet (checked that neither ip address are used). But whenever i failover the AG to the secondary, and try and connect via the listener it fails,
I am trying to connect via SSMS from the primary instance. and just time out, If i roll over to the primary i can connect no issues, I've tried playing with the connection settings, upping the time out to 30 secs, adding the MultiSubnetFailover=true. etc but not getting any joy.
We have a bought in application written in Visual Basic 6 using ADO 2.7 to connect to SQL Server. The application has two connections strings and uses internal logic to determine which of the two connection strings connects to a read-write database. It does something as simple as trying an update that makes no changes to a very small table somewhere.
Previously this application connected to a Mirrored Database hosted on two Windows Server Failover Clusters and SQL Server 2005.For the future the App will be connecting this application to a SQL Server 2014 Availability Group.The Availability Group is made up of four servers, in a cluster, two at one site on Subnet A and the other two at a second site on Subnet B. The Availability Group has been given a Listener with a DNS name of AGLISTEST on port 1433 with two Static IP addresses, one for each subnet.
Our Contractor has configured the Application’s connection strings to connect to the two Static IP addresses assigned to the AG. He is of the opinion that although ADO has zero understanding of an Availability Group, at least one of the Static IP Address will translate to the Availability Group primary server because it is a Cluster Resource and so act like a Cluster IP Address on Windows Server Failover Cluster; i.e. sort of mimicking the previous configuration. This does work and he has demonstrated it, however I can’t find any article that proves to my satisfaction this is intended behavior not something that accidentally works. If it is accidental behavior then that would be something that might stop working at an unexpected point in the future.
All the research I have found relates to connecting to the AG Listener name, and all the multi-subnet issues and Active Directory issues that go with connecting using what is a legacy client.So; the question is, is this translation / redirection of static IP Addresses assigned to an Availability Group listener documented and safe?
I've two instances(Default, Named[dynamicsFINANCE]) running on SQL server 2014. However, when I try to connect to named instance say (dynamicsFINANCE) using SQL authentication from local SSMS, I get below error message:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)
I assigned a static port number to the named instance [dynamicsFINANCE] 1450. I also setup the firewall rule to allow access to Port 1450.
I have a 3 node cluster on which I have installed SSAS as it's own insntance. I have created this as a named instance and can connect to it by serverinstance if I'm on the server itself. However from my desktop I get the error saying instance was not found on server name.
I have defined an alternate port and setup firewall rules and can connect via server:port but not serverinstance. Prior to making this change SSAS was running on default port of 2383 and I could connect just by servername.
I have read many articles for previous versions saying that clustered SSAS will always use 2383 and that you must connect just using servername. However and this is were it gets strange. I have a 2 node UAT cluster with SSAS setup exactly the same way I've described above and I can connect from my desktop as serverinstance.
Should I be able to connect as serverinstances for a named clustered instance in 2012 ?
I have a 2 node cluster with 2 standalone 2k14 instances having alwayson setup. As per client requirement we have created a client access point with a cname alias in dns to connect to secondary replica. Now, everytime whenerver the roles switch over one has to manually move this resource from the previous secondary node to the new secondary node. This is tedious, and should not be done manually either, so I am looking for a way to automate it so that as soon as the role switches over, the resource group after some time should also switch over to the current secondary.
I setup an availability Group. (Only 2 servers - Primary And secondary) -- 21 , 22
I also define an listener . IP .. 23
1- In First step I connected To Listener (23) And in a while I inserted A record to a table .
While 1=1 insert into Tbl_T1(f1,f2) Values (1,2)
2- in second, I Stop the primary .
- I expected this while whitout disconnect, continue.
3- The while code stopped whit this message :
Msg 64, Level 20, State 0, Line 0 A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The specified network name is no longer available.)
4- I execute again the script, And it worked in new primary.
My questions :
1- is the listener disconnected between switched primary and secondary ? OR have we data loss between switching?
2- I did some huge update on Primary that fill the Log fiel space. And in last Update I got this error :
Msg 9002, Level 17, State 2, Line 27
The transaction log for database 'Your_DB' is full due to 'LOG_BACKUP'.
Is this (Fill All space) a reason to switch primary? Or not ?
Environment: SQL Server 2014 on Windows Server 2012 R2.
We have our availability group configured and working. However, when we try to connect to the AG listener from a remote server, we have to use the fully qualified domain name (FQDN) to connect. We'd like to be able to connect just using the host name. Interestingly, ping actually resolves the IP correctly for either.
I am new to SQL and I am trying to have a column in my table that points to images I have stored in a directory on my system. I cannot seem to get it to work correctly and I am wondering if someone might be able to help. I want to use this image for each record with the other information on my windows form but I cannot seem to get the file pointer right. Any help would be appreciated. Thanks.
I want to move one database from the source SQL Server 2000 instance to a new SQL 2000 instance in another machine. I have five user databases in this source SQL instance. How should be my approach to move this single database out of this ? My understanding is restoring this database in the new instance, copying all logins to the new instance and then copying the jobs, DTS packages, alerts, operators only specific to this database will do it. Please let me know if this is exactly what I should do ..

i have installed SQL client instance on my Desktop "Machine-A", and i used to connect to SQLServer2000 running on another "Machine-B" by using valid username and password.
i created a DTS package and i used to run it. im very confused how the communication happens between the two machines and which process run where and which initiates which and which machine allocates waht resources. im really interested to know all these things. if any one know plz help me out.
now, when in insert a row in "TV" the foreign key "IdCamera" will relate to a row in either "InfraredCamera" or in "DaylightCamera" depending on the "DeviceType" value.
in other words, if i insert a row with DeviceType=0, then IdCamera will have to point to a row in the "InfraredCamera" table. And if i insert a row with DeviceType=1, then IdCamera will have to point to a row in the "DaylightCamera" table.
so, my question is, how can i make the constraints relationship so that the idCamera relates to a row in DaylightCamera or in InfraredCamera depending on the value of DeviceType? should i make 2 foreign keys with allow null? or should i place both relationships to the same foreign key? im not sure what to do
Thanks guys for your help. it is really appreciated!
How do I "point" a set of stored procedures to operate on different linked servers?
In other words, I have the following linked servers:
DatabaseA DatabaseB DatabaseC DatabaseD ...and in the future, there may be added additional linked servers.
All the linked servers have identical schema, but they contain unique data--each linked server represents a company.
I have a database which will contain stored procedures which I will want to operate against these linked servers. How can I "redirect" my stored procedures to operate against a chosen linked server?
If these were not linked servers, but SQL Server databases, I'd be able to replicate the same stored procedures in each database. Then, when I called a stored procedure, it would act against the data in that database. But these aren't SQL Server databases, so that idea is out.
Unfortunately, the USE command cannot be used within a stored procedure, and even if you could, I can't get it to respond to a database name given as a variable. That idea is out.
The only alternative I have left is to use the string catenation facility of the EXECUTE command. Unfortunately, with 100s of complex queries, setting that up is going to be a nightmare.
I am using a WMI Event Watcher task to watch for files dropped into a directory over a network drive.
It seems to work fine when it is pointed to a physical drive name, but not when I use a machine name.
I.e.
This works - SELECT * FROM __InstanceCreationEvent WITHIN 10 WHERE TargetInstance ISA "CIM_DirectoryContainsFile" and TargetInstance.GroupComponent= "Win32_Directory.Name="C:\\temp\\folder1\\folder2\folder3""
This fails - SELECT * FROM __InstanceCreationEvent WITHIN 10 WHERE TargetInstance ISA "CIM_DirectoryContainsFile" and TargetInstance.GroupComponent= "Win32_Directory.Name=\\\\machineName\\folder1\\folder2\\folder3"
The failing code does not throw any errors (i.e. SSIS thinks the WQL syntax is correct), but it doesn't pick up any dropped files.
Am I doing something incorrect with the syntax, or must I use a physically mapped drive letter?
I am not sure if this is necessarily a simple question, but I'm somewhat new to SQL so I thought maybe there's an obvious answer I just don't know about.
The problem is that I have one "master" table, and a child table that has two foreign key references back to that master table. Both of these foreign key constraints are marked as "on delete cascade" with the intention that should a row from the master table be deleted, any rows that reference that object in EITHER foreign key field should be deleted.
I am wondering why this causes a cycle. It seems logical enough to me, it just involves two passes of the table, one for each affected column.
Got windows Vista Business edition, installed Visual Web Developer Express, SQL Server 2005 Express SP2, SQL Server Management Studio SP1 in that order. I was developing in VWD express without problems using WinXP but now on Vista Business, the local connection to SQL server appears to be a problem. I know there's nothing wrong with my web.config or anything like that as it was working perfectly prior to running under Vista. If i specify the database on the live website, it works fine. If I specify the test database in app_data folder, I get the following exception:-
Server Error in '/UKSD' Application.

I am taking a guess it's somerthing to do with access issues, but can't find anything out on searching the forums etc.. I am setup as an administrator, running VWD as an administrator and for the record, SQL Server Management Studio express works fine. Another small issue, when I run the application from VWD, I always have to minimise the application and restore it as the graphics get corrupt. Please help!! I cannot debug when running of the live website.
One of our developers has written a view which will execute completely (returns ~38,000 rows) in approx 1 min out of SQLMS (results start at 20 sec and completes by 1:10 consistently).
However, if he adds a data flow task in SSIS, adds an OLEDB Data Source and selects Data Access Mode to "Table or view" and then selects the same view, it is consistently taking over 30 minutes (at which point we've been killing it). I can see the activity in the Activity Monitor, it is doing a SELECT * from that view and is runnable the whole time.
If we modify the view to SELECT TOP 10, it returns in a short time.
Has anyone run into this problem? Any suggestions? It is very problematic, as if the views change we have to hack around this problem.
As a starter i tried to modify and translate the Personal Website Starters kit from the VS2005Team SDK.
When i'm working on the machine were it's installed , under debugging, all works great.
But when i try to develop from my laptop, via RDP on the develop machine, i've got this message and can not debug (connect to the SQLxpres Server)
