SQL Cluster with FQDN only (no instance names)

Is it possible to setup a SQL failover cluster with multiple instances but basically be named the "default instance".
Right now I have three instances: AAA, BBB, and CCC. With failover clusters you associate each SQL instance with its own Drive, its own cluster name, etc. So right now this is how you connect:
aaa.db.domain.com\AAA
bbb.db.domain.com\BBB
ccc.db.domain.com\CCC
Is there a way that you can make it where people can connect by not providing an instance name? Because there is always only one instance per virtual server / fqdn:
aaa.db.domain.com
bbb.db.domain.com
ccc.db.domain.com
I hope I explained well enough. Thanks in advance!

So Azure is not using a regular SQL server? I figured they were just using SQL 2014 or such because they offer Azure services for on-premisis now in your own datacenter.
SQL Azure is definitely not the same as an on-premises SQL Server.

  • Sql cluster with Always on

    Hi
    I have 2 sites Ho & DR
    I have 2 sql servers in each site
    I need to make on each site sql cluster and between the 2 sites we need to make always on
    please need the steps for this scenario

    Hi Yasser,
    According to your description, you want to setup a disaster recovery solution combining SQL Server Failover Cluster in Primary Datacenter and Availability Group on a SQL Server Failover Cluster in Secondary Datacenter. Assume that, in the Primary DataCenter,
    SQL_PV is the FCI instance and CLP_1 and CLP_2 are the two nodes. In the Secondary DataCenter, SQL_SV is the FCI instance and CLS_1 and CLS_2 are the two nodes as the screenshot below shows.
    To achieve the goal, you could follow the steps below:
    1.Add two nodes CLS_1 and CLS_2 from secondary datacenter into the existing
    Windows Server Failover Cluster(WSFC). Please note that all nodes for an availability group must exist on a single WSFC within the same Active Directory domain, even between datacenters.
    2.Configure Shared Storage for both CLS_1 and CLS_2 nodes.
    3.Install FCI instance of SQL 2012 Enterprise edition using "New SQL Server Failover Cluster Installation" and join the other secondary node using Add node to a SQL Server failover Cluster.
    4.Enable Always on Availability Group on newly installed FCI.
    5.Define the possible owner for each SQL Server FCI as the following:
    a. Go to "SQL Server" services on the Cluster instance under SQL_PV group and go to SQL Properties. Under Advanced Policies, choose only CLP_1 and CLP_2 as possible owner for SQL_PV.
    b. Go to "SQL Server" services on the Cluster instance under SQL_SV group and go to SQL Properties. Under Advanced Policies, choose only CLS_1 and CLS_2 as possible owner for SQL_SV.
    For more information about the process, please refer to Scenario 2 in the article:
    http://www.mssqltips.com/sqlservertip/3150/adding-sql-server-alwayson-availability-groups-to-existing-failover-clusters/

  • SQL Cluster with Mirroring

    Hello All...........Consider following:
    We need to build a two-2 node failover cluster in following manner:
    OS:  Windows 2012
    SQL: SQL 2012
    Node_A                                     Node_B
    =====                                    =====
    SAN_A_Storage                          SAN_B_Storage (Both servers with their own Storage, FSW to be used for Quorum)
    Instance_A                                 Instance_B
    Each server would have its own Instance that is Node_A would have Instance_A and Node_B would have Instance_B.  Mirroring would be configured vice versa that is Mirror copy of Node_A would be on Node_B and Node_B's mirror copy would be on Node_A. 
    In other words, both instances would be active at the same time with mirror copy on the other server.
    Is this doable? 

    Thanks for the reply.
    Actually, I have to implement the solution based on a design that has been handed over to me.  But, since it made me confused, so, I turned here for guidance.  So, design-wise, I cannot change anything.
    I fully understand that HA can be achieved directly through a two-2 node cluster.  I also, get your point that in common mirroring scenarios, either a cluster is mirrored to a DR site cluster or a single server, but in my scenario, the cluster is the
    same at HA and DR sites.
    Following are some clarifications with regards to environment:
    Design is such that it involves two-2 sites A and B where both sites have their own Storage (no storage replication).  FSW will be present at a third-3 site for quorum.  The cluster would be a stretched cluster (Fiber connectivity between
    sites).  Each site node would run instances of their site with its mirror copy being placed on the other site's node.
    Mirroring was chosen due to supportability limitation otherwise AOAG is in place for such scenarios.  But, since I have not encountered this situation before, so, I am just verifying if this workable or not?  As I have a few more questions after
    this, but just wanted to make sure that it is supported in SQL 2012.
    THanks.

  • How to restart an entire J2EE Cluster - With multiple hosts and instances

    I am looking for a definitive answer on the right way of Restarting an SAP Enterprise Portal CLUSTER without an ABAP stack.
    Currently the process is to use ssh into each box and either jcmon pf=<profile> then restart instance, or ssh into each host and run startsap/stopsap on each.
    Is there a better way?

  • Adding SQL Cluster to MARS

    What is the best way to add the physical servers and SQL server instances to MARS?
    As a bit of background we have a SQL cluster with 3 physical servers and each one has an ip address. There are also 3 SQL instances with an associated IP address. These are similar in nature to virtual addresses. Both the physical servers and the SQL instances have their own netbios name.
    Do we add both the physical servers and the SQL instances to MARS?

    Hi Fredrik,
    There are alot of events on the IDSSM but these events aren't appeared on MARS although IDSSM is successfully discovered by MARS. That's also happened with Cisco NAC appliance which i added it to MARS but there are no incidents for it on MARS.

  • Changing Instance Name - spfile

    Hello guys,
    i've got a little question about changing instance names and values.
    For example i got the following spfile (only example values):
    *.db_name=DB1
    DA1.shared_pool=9000000
    DA2.shared_pool=8000000
    and so on...
    So the db_name DB1 is valid for all instance identifiers.
    But how can i specify manually with which instance name the oracle db server should start? (for exampe DA1 and DA2)
    The standard spfile name can also not be used, because of oracle searches normally for $ORACLE_HOME/dbs/spfileSID.ora file?
    And which value is preferred, if i have a value for all instances (*.shared_pool) and a value for the specfied instance (DA1.shared_pool)... which parameter is valid if both are specified in the spfile?
    Thanks and regards
    Stefan

    hi,
    Every Instance having there own spfile<sid>.ora.hmm that sounds very strange to me. Because of the option with the identifier in front of the parameter (*= for every instance, DA1 = only for instance with name DA1).
    I read about the advantage only having one spfile for more instances (for exampe RAC).
    So maybe there is a possibility, to start an instance with the specified name (in my example DA1 or DA2).
    I don't want to change the DB name... only the instance name so that i can easily start the same db with different parameters (=different instance name)..
    Thanks

  • Flash CS5 instance name problems

    I can't give instance names in my AS2 project. When I click on the Instance Name box it is locked. I can only give instance names to the text objects. Movie clips and buttons are locekd. Please Help

    Hey guys,
    I struggled with this too.
    It seems if you make a reference to it in the action script it allows you to set an instance of that name (basically. why would you need to set a name if there is no reference to it in the action script)
    e.g add something like
    mc_myMovieClipName.addEventListener(MouseEvent.MOUSE_OVER, myFunction);
    and you will be allowed to rename a new symbol of that name.
    (or change your existing references to your OLD movieclip name and you will be allowed to rename it)
    If there are 2 symbols on the stage and only 1 reference in the code. only 1 symbol will be allowed to be named and you will have to add...
    mc_myMovieClipName2.addEventListener(MouseEvent.MOUSE_OVER, myFunction2);
    to the code in order to name the second movieclip.
    Please let me know if this helps.

  • Acquiring movieclip instance names

    I need to write a function that retrieves the instance names of movie clips without knowing what those instance names are.
    Here's the scenario:
    The timeline reaches a frame which has a movieclip with an instance name of "bigClip"
    bigClip itself holds a number of movieclips, each with its own unique instance name. On the enterFrame of bigClip, I want to retrieve all the instance names that are on bigClip and put them in an array.
    I can't seem to figure this out. Any guidance would be much appreciated.
    Thanks,
    David

    Well I doubt you want to do it on the enterframe of bigClip. Do you really need to find the names of all the clips 30 times a second every second that big clip exists? I'm guessing/hoping you just mean when bigClip starts.
    In any event you can make a function that returns an array. Perhaps something like this:
    function findChildrenClips(clip:MovieClip):Array{
    var theClips:Array=new Array();
    for(var a in clip){
    if(typeof(clip[a])=="movieclip"){
    theClips.push(clip[a]);
    return theClips;
    Then on the frame where big clip exisits you can do this:
    var foundClips:Array=findChildrenClips(bigClip);
    Now if you really want to do this onEnterFrame you could probably do it, but there is probably a better way to structure your file in that case.

  • SQL Server 2008 R2 Express with SP2: 'SQLEXPRESS'-instance installation fails while any other instance name installation succeeds.

    We supply our software package that also includes the unattended installation (with /QS and so on) of SQL Server R2 Express (with SP2).
    The setup works good in about 99.9% cases, but one customer complained that after the "successful SQL Sever installation (at least, it looked so!) he could not open the supplied database getting some strange error messages...
    After some months of trial-n-error attempts we are now able to reproduce the problems this custumer had. But we cannot find the reason of the problem.
    So the test computer is a virtual machine with Windows 7 + sp1 32-bit.
    Among the programs/tools installed on this machine there were (in the following order):
    SQL Server 2008 Express - the default SQLEXPRESS instance
    SSMS
    VS 2010 Pro (German)
    SQL Server 2008 Express R2 (with SP 1 or SP2 - ?) - the default SQLEXPRESS instance
    Then some of them were uninstalled in the following order:
    SQL Server 2008 Express
    SSMS
    SQL Server 2008 Express R2 
    Now we tried to install (in normal mode with UI) the SQL Server 2008 Express R2 with SP2.
    When we chose the default SQLEXPRESS instance - it failed with the following info:

    What could be the reason of the problem (and only for SQLEXPRESS instance that was earlier installed and then uninstalled)? I will provide the complete Detail.txt file if needed. 
    How could we check (if we could) the conditions so some name would be allowed as an instance name for SQL Server installer to success?
    With the best regards,

    Thank you Lydia!
    Unfortunately the simple check the registry
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names\SQL does /did not work in our case since there is no any instance
    name there,
    However there seem to be some "rudiments" under
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and/or HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services.
    So I will now try to check the subkeys of these two keys as it was mentioned by Xiao-Min Tan.

  • Get current SQL instance name with PowerShell

    Hi all,
    I'm preparing SQL agent job that will backup all jobs on SQL server. Main step is PoswerShell script. I want that job to be universal for all servers. The first parameter that I need to send to script is instancename.
    I want to use variable as InctanceName parameter. So, when I run this job on particular server this variable must get current SQL instance name.
    I can use $env:computername for default instances but I cannot use it with named instances or with clustered instances. Some solutions like using 'HKLM\SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names\SQL' keys won't work because of number of
    instanses can be running on one machine.
    How to get only current SQL instance name?

    Hi, 
    Thank you for your answers.
    I found this solution:
    $serverInstance = "$(ESCAPE_DQUOTE(SRVR))"
    Working perfect.

    Let's assume you have two DBMS instances running on the machine hansa. One
    of them may be listening for tcp connections on port 1433, but the other must not.
    The other most be listening on some other port number you have chosen.
    Therefore, to choose which DBMS instance you want to connect to, use the
    working URL you have, and switch the port number as desired.

  • Connection failed SQL Server 2008 R2 with Instance Name but with IP connect

    Hello,
    We have a server where SQL Server 2008 R2 is installed. Now from our local pc we connect to that database. I try to connect that database using instance name but cannot. If I put IP Address in the server name field, then it connect. my other colleague, they
    can connect using instance name but I cannot.
    How can I resolve this problem? How can I connect using Instance Name?
    Please help.

    Faisal there are a couple of possibilities for you. Some have been mentioned already. For us to help if you can provide some further information this would be appreciated. In the mean time some things that you can check
    If you are able to connect to the instance via Server IP Address then the instance is configured for remote connections and the firewall does allow for remote connections to come through. You can check the SQL Server Configuration Manager on the server to
    check what protocols (Named Pipes & TCP/IP are enabled). You can also check that the Browser is running.
    What error message do you receive when trying to connect via the ServerName or ServerName\InstanceName remotely?
    You could look at creating an entry in your host file with the server name and IP address on you workstation and test this. I am thinking that if a colleague is able to connect remotely via ServerName or ServerName\InstanceName that you potentially have
    a caching issue or a DNS issue. Are you able to ping the servername from your workstation and get a valid response from the correct IP address?
    I hope this helps.

    The system cannot find the file specified
    I have tried from so many forms. This is so frustrating. Thank for everyone/anyone who wants to help. So this is what happened: I had to uninstall my previous sqlserver 2012(which worked great) for some reason, and I uninstalled everything from that download.
    Then I installed the trial edition of sql server 2012 (64 Bit) and It wouldn't connect to the database. (Error mentioned above.) My local DB is COWBOYS. (COWBOYS is also my computer name.) After this, I have tried downloading sqlexpress and sqlserver 64bit
    many times and cannot connect to my local DB. 
    How do I connect to my Local DB? 
    Also, I think this might help: (When I run sqlserve.exe, which I was able to find in C:\Program Files\Microsoft SQL Server\110\LocalDB\Binn, I get an error: Your SQL server installation is either corrupt or has been tampered with(Error getting
    instance ID from name). Please uninstall then re-run setup to correct this problem.
    I would happily re install it, if it wasn't my 20th time.
    I don't have any remote connections, I don't use username/password, only window authentication. I work mostly on visual studio, but without able to store /retrieve data, I don't know how to survive.
    May be the solution is very simple, but I am too frustrated. 
    Some of the things I have tried:
    From a command prompt, enter one of the following commands:
    net start "SQL Server Agent (MSSQLSERVER)" OR 
    net start "SQL Server Agent(instancename)"(for instance)
    on my sql configuration, I cannot start anything because there is nothing there to start. I can post more details, if that would help. Also, some more details about the error:

    Any one that can help me, I will be greatful. Thank you so much. p.s. please ask me anything if you have any questions.

    It sounds like there are a couple things going on here.  First check if you have a successful install of SQL Server, then we'll figure out the connection issues.
    Can you launch SQL Server Configuration Manager and check for SQL Server (MSSQLSERVER) if default instance or SQL Server (other name) if you've configured your instance as a named instance.  Once you find this, make sure the service is started. 
    If not started, try to start it and see if it throws an error.  If you get an error, post the error message your hitting.  If the service starts, you can then launch SSMS and try to connect.  If you have a default instance, you can use the machine
    name in the connection dialog.  Ex:  "COWBOYS" where Cowboys is the machine name.  However, if you named the SQL Server instance during install, you'll need to connect using the machine\instance format.  Ex:  COWBOYS\Romo (where Romo
    is the instance name you set during install).
    You can also look at the summary.txt file in the SQL Server setup error logs to see what happened on the most recent install.  Past install history is archived in the log folder if you need to dig those up to help troubleshoot, but the most
    recent one may help get to the bottom of it if there is an issue with setup detecting a prior instance that needs to be repaired.

  • Can we install a new mssql cluster on the same windows cluster which already containes a mssql cluster with named instance

    We have a MSSQL 2008R2 Enterprise edition with a two node active passive fail-over cluster running on 2008R2 windows cluster with out any issues,
    Now my question is can we add one more MSSSQL cluster instance for the same setup with out disturbing the existing one ?
    Also give thoughts on load sharing as the second node is mostly ideal now except fail-over scenarios,
    Why we go for this situation is because of the collation setting which can be set only one per instance(Database collation setting change not working), we need a different default collation for the new setup

    hi,
    >>Now my question is can we add one more MSSSQL cluster instance for the same setup with out disturbing the existing one ?
    Yes it is possible .You need to add new drives as cluster aware and install SQL server and put data and log files on thse drives.YOu would need to create named instance of SQL server and need to create different resource group.Both old installation and new
    onw would work separately.
    >>Also give thoughts on load sharing as the second node is mostly ideal now except fail-over scenarios,
    Good point indeed.You are about to create Multi instance cluster and should plan for scenario where one node is down and other node is handling load for both instances.Memory and CPU should be enough to handle the load.
    >>Why we go for this situation is because of the collation setting which can be set only one per instance(Database collation setting change not working), we need a different default collation for the new setup .
    Just for collation if you are installing new instance seems little wierd to me.You can manage collation at column ,database and at server level.
