Extending Physical Cluster into Virtual Cluster

Hello All...........I have a Physical SQL Cluster cluster.domain.com (Physical_NodeA and
Physical_NodeB) using SAN A.  Physical SQL Cluster contains
three-3 instances.  I intend to move this cluster into my Hyper-V Failover Cluster enviornment and I want to get rid of both Physical nodes (Physical_NodeA and
Physical_NodeB) along with shared storage on SAN A.  I have devised following approach:
-  Extend existing Physical Cluster cluster.domain.com on
(Physical_NodeA and Physical_NobeB) with shared storage
SAN A
    - By adding Virtual Nodes (Virtual_NodeC and
Virtual_NodeD) to cluster.domain.com
- Creating LUN/s that are shared by all four nodes (Physical_NodeA, Physical_NodeB, Virtual_NodeC and Virtual NodeD) on
SAN B
- Moving Instances/Databases location to new LUN/s on
SAN B
- Failover to new Virtual Nodes either Virtual_NodeC or
Virtual_NodeD
- Evict Physical_NodeA and Physical_NodeB
- Remove Physical_NodeA and Physical_NodeB from Host Group at
SAN A
- Remove LUN/s from SAN A.
Your thought on above procedure would be appreciated.

I am not sure why you want to do all of these.
Why cant you just get the new virtual environment up and running with SQL Server and just migrate the databases to the new cluster?
I think the amount of downtime you incur would be less in this approach.

  • Restore the deleted extended IIS web site into Virtual directories

    Hi,
    i deleted the IIS site from virtual directories and as well from IIS. But still i can see the extended web site zone in the Central administration, General Settings from the remove SharePoint from IIS web site. now question is there any way i can restore
    the deleted iis site zone any how?
    Thanks

    Hi Trevor,
    Thanks for your answer. i need some suggestion regarding on going issue. First i have created a web application at port 80 when it was in singer server and then i extended to 443 and 80 in multi-tier farm as you can see in the below image
    And then i deleted IIS site from IIS itself and from Virtual directories as you can see in the below picture. Then i blinded the "SharePointDemo-80" site with host header at port 443 With default zone AAM. now i can access the site well but problem
    is if i want to deploy any custom solution, getting error "The web.config is invalid on this IIS web site: "C:\inetpub\wwwroot\wss\VirtualDirectories\demoportal.bbcat.local80\web.config. " and also crawler is not crawling any items. my
    understanding is, as there is no IIS site into virtual directories obviously will throwing error. Usually first i create web application at different port (example 8080) and then extend the application to 80 or 443.  As i have already place this web application
    and did customization, what will be the best way to handle this situation?
    Thanks in advanced!!

  • Loading multiple physical records into a logical record

    Hello,
    I'm not sure if this is the right place to post this thread.
    I have to import data from a fixed length positioned text file into a oracle table using sql loader.
    My sample input file (which has 3 columns) looks like:
    Col1 Col2 Col3
    1 A abcdefgh
    1 A ijklmnop
    1 A pqrstuv
    1 B abcdefgh
    1 B ijklmn
    2 A abcdefgh
    3 C hello
    3 C world
    The above text file should be loaded into the table as:
    Col1 Col2 Col3
    1 A abcdefghijklmnpqrstuv
    1 B abcdefghijklmn
    2 A abcdefgh
    3 C helloworld
    My question: Is there a way tht i can use the logic of loading multiple physical records into a logical record in my oracle tables. Please suggest.
    Thanks in advance.

    Kulash,
    Thanks for your reply.
    The order of the concatenated strings is important as the whole text is split into several physical records in the flat file and has to be combined into 1 record in Oracle table.
    My scenario is we get these fixed length input files from mainframes on a daily basis and this data needs to be loaded into a oracle table for reporting purpose. It needs to be automated.
    Am still confused whether to use external table or a staging table using sql loader. Please advise with more clarity as am a beginner in sql loader. Thanks.I still think an external table would be better.
    You can create the external table like this:
    CREATE TABLE     fubar_external
    (      col1     NUMBER (2)
    ,      col2     VARCHAR2 (2)
    ,      col3     VARCHAR2 (50)
    ORGANIZATION  EXTERNAL
    (       TYPE             ORACLE_LOADER
         DEFAULT DIRECTORY  XYZ_DIR
         ACCESS PARAMETERS  (
                                 RECORDS DELIMITED BY     NEWLINE
                          FIELDS  (   col1        POSITION (1:2)
                                      ,   col2        POSITION (3:4)
                               ,   col3        POSITION (5:54)
         LOCATION        ('fubar.txt')
    );where XYZ_DIR is the Oracle Directory on the database server's file system, and fubar.txt is the name of the file on that directory. Every day, when you get new data, just overwrite fubar.txt. Whenever you query the table, Oracle will read the file that's currently on that directory. You don't have to drop and re-create the table every day.
    Note that the way you specify the columns is similar to how you do it in SQL*Loader, but the SEQUENCE generator doesn't work in external files; use ROWNUM instead.
    Do you need to populate a table with the concatenated col3's, or do you just need to display them in a query?
    Either way, you can reference the external table the same way you would reference a regular, internal table.

  • Can I use an airport extender to wire into a Bluetooth dvr?

    Can I use an airport extender to wire into a Bluetooth dvr?

    Potentially yes. For example, you can configure an 802.11n AirPort Express as a wireless Ethernet bridge. In this mode, the Express would connect to an existing Wi-Fi network and its LAN port would be available to wired clients for network/Internet access.

  • Duplicate physical channel with virtual channel

    I accidently created more than global virtual channel with one physical channel, for example:
    physical channel  global virtual channel
    a0                       vtc00
    a0                       vtc01
    a0                       vtc02
    My questions are:
    1-How do I change the virtual channel as the following:
    physical channel  global virtual channel
    a0                       vtc00
    a1                       vtc01
    a2                       vtc02
    2-How do I re-name/delete the global virtual channel, when it's not in the task?
    Thanks you for your time, Dylan
    Solved!

    Thanks you Carisa for fast response, but that not the right answer I am looking for. 
    May be I did not make myself clear.  I attached two screenshots for example: On one screenshot, you will see bri00, bri01, bri02, bri03, bri04, bri05, bri06, bri07, bri08, bri50 on the virtual channel tab, however you won't see them display under NI-DAQmx Global Virtual Channel (second screenshot).  On the second screenshot, you only see bri00, bri01, bri02, bri03, bri04, the rest of bris do not display on here like they display on the virtual channel tab. 
    Now I can't create the new global virtual channel under NI-DAQmx Global Virtual Channel with the name bri05, bri06, bri07, bri08, because I will get the conflict name error pop up on the screen.  How can I delete those bris in the virtual channel tab? 
    Thanks again for your time, Dylan

  • JTable that does not show unless physically click into center JPanel.

    I update a JTable with a new resultSet and I cannot see the table unless I physically click into the centerPanel of the JFrame where the Jtable is held. Once I do that the data is updated - but I need it to show without any action. I have never encountered this problem before, any advice would be greatly appreciated. Thank you in advance for your advice and time.

    use table.setModel(...) and it will repaint itself.

  • Physical Address to Virtual address

    Hi all,
    Are there any DDI/DKI API's to convert physical address to virtual address and vice versa. If there are no API's available is there any other way/method to achive this.
    Regards and Thanx in advance
    Pradeep

    in general, you're not supposed to need to do that, although hat_getpkfnum will work. If you are trying to use dma, it is better to use the dma functions such as ddi_dma_alloc_handle with ddi_dma_mem_alloc and ddi_dma_addr_bind_handle, or dvma_kaddr_load.

    Putting this here as well:
    I don't believe this is documented anywhere.   I typically see 6 cores, but I've run with 4 or 8 but in the end it's all about watching performance.
    System Center Advisory for Lync can complain if it's not at least 8.

  • Moving Physical Cluster into Virtual Cluster

    Hello All...........I have a Physical SQL Cluster 1 cluster1.domain.com (Node A and
    Node B) using SAN A.  Physical SQL Cluster contains
    three-3 instances.
    I have built a Hyper-V Failover Cluster and upon it I have also built a Guest/Virtual SQL Cluster 2
    cluster2.domain.com (Node A and Node B) using SAN B.
    Now, I want to move the instance/databases from Physical SQL Cluster 1 cluster1.domain.com to Guest/Virtual SQL Cluster 2 cluster2.domain.com.  Is this supported?
    Or do I have to add the Virtual Nodes (NodeC and
    NodeD) to cluster1.domain.com and then failover the
    instances/database to new virtual nodes and then remove the Physical Nodes (NodeA and
    NodeB).
    Also, confused as to how would I manage the Storage as old Physical SQL Cluster
    cluster1.domain.com uses SAN A and I have new Virtual SQL Cluster
    cluster2.domain.com on SAN B.  Would I be requiring to change the instances/databases location as well?
    Any help on this would be appreciated.   
     

    Hello,
    There is a good bit of different things going on here so I'll try and make it short.
    Normally, it wouldn't be a problem to add in new nodes (virtual) to the current physical, install SQL Server, and eventually evict the physical nodes in order to migrate. However, you're using a different SAN for the storage. You could *still* do this, but
    you'd need to have SAN replication on the backend between the two and set it up very much like a 2008/R2 geo-cluster.
    The *easier* way, depending on clients, would be to either log-ship or mirror the databases to the new instances. When you have time to cutover, fail the mirrors to the new cluster and then remove mirroring. The clients would need to either be aliased or
    re-pointed. It could be done less cleanly by using a cname change for the old to the new but I'd stay away from that.

  • Moving Physical SQL Cluster into Virtual SQL Cluster based on Hyper-V Failover

    Hello All............I have a SQL Cluster based on Physical Hardware that has Three-3 instances as well. I have setup a Hyper-V Failover Cluster (2012 R2) and have built Virtual/Guest SQL Cluster (2012 R2) upon it.  Now, I intend to move
    the instances/databases from Physical SQL Cluster to Virtual SQL Cluster.
    1.  Is this supported?  If so, I would appreciate any guidance on it?
    2.  Is P2V of SQL Cluster supported in Hyper-V Failover Cluster based on Windows Server 2012 R2?

  • How to migrate SQL Cluster into Virtual SQL server or Virtual SQL Cluster

    Hello All,
    Currently we will be attempting to migrate a SQL cluster of (2 systems) into are virtual enviroment.  We have been tracking the system requirements with Vmware Consolidation Tool and IO Meter to make sure our hosts have enough resources to accomidate this.  All the metrics coming back looks like it will run just fine virtulized as the cluster was just for failover purposes anyhow and not for performance purproses.  With that said a few questions have come up.
    1.)  What is the best way to virtulize this or to convert it (P2V)
         -  Should we just create a new Virtual Machine and install the same version of SQL and do a manual migration to the new SQL server and leave it as 1 SQL server with HA
         -  Or is there a way to P2V this kind of a setup ? if so what are the steps involved?
    2.)  If a P2V is possible I was under the impression that you will have to use a RAW mapping for the hard disks otherwise the cluster will not work ?  Can anyone speak to this? as I'm pretty sure I have clustered windows server 2008 without RAW mapping before but not with SQL

    Another quick question.  The Vmware SQL Clustering KB article says:
    vSphere MSCS Setup Limitations
    Before you set up MSCS, review the list of functionality that is not supported for this release, and any
    requirements and recommendations that apply to your configuration.
    The following environments and functionality are not supported for MSCS setups with this release of vSphere:
    n Clustering on iSCSI, FCoE, and NFS disks.
    n Mixed environments, such as configurations where one cluster node is running a different version of ESX/
    ESXi than another cluster node.
    n Use of MSCS in conjunction with VMware Fault Tolerance.
    n Migration with VMotion of clustered virtual machines.
    n N-Port ID Virtualization (NPIV)
    n With native multipathing (NMP), clustering is not supported when the path policy is set to round robin.
    n You must use hardware version 7 with ESX/ESXi 4.0.
    Can you not do clustering if your shared storage is iSCSI ? or can you not do RAW mapping with it to create the cluster ?

  • Using dbca to extend RAC cluster error

    Hi all,
    I'm trying to extend my 11gR2 RAC cluster (POC) using the Oracle documentation (http://vishalgupta.com/oracle/docs/Database11.2/rac.112/e10718/adddelunix.htm). I've already cloned and extended Clusterware and ASM (Grid Infrastructure) to the new node, as well as cloned the RAC database software to the new node. When I run the below statement to have dbca extend add a new instance on the node for the RAC I get the error shown:
    CMD:
    $ORACLE_HOME/bin/dbca -silent -addInstance -nodeList newnode13 -gdbName racdb -instanceName racdb4 -sysDBAUserName sys
    -sysDBAPassword manager123
    ERROR:
    cat racdb0.log
    "Adding instance" operation on the admin managed database racdb requires instance configured on local node. There is no instance configured on the local node "newnode13".
    I set ORACLE_HOME before running dbca, and I've also tried setting ORACLE_SID to both racdb4 and racdb, no change. My environment is below, any help is appreciated.
    OS: SLES 11.1
    Database: 11.2.0.1
    Existing Nodes: node01,node02, node03
    New Node: newnode13
    DB Name: racdb
    Instances: racdb1, racdb2, racdb3
    New Instance: racdb4
    Thanks.

    Silly me, I was running the command from the new node instead of an existing node. I guess it was a rough weekend after all. Thanks all!

  • Running 9i RAC and 10g RAC on the same physical cluster

    We are planning to run 9i RAC ( with OCFS2 ) and 10g RAC ( ASM ) on the same cluster with 4-Nodes.
    I will really appreciate if any of the forum members can share the information and experiences if the have done such implementation. We are currently running six 9i R2 clusters and are in the process of migrating them. The current need is to make the 9i and 10g cluster co-exist up to a certain point.
    Thank You,

    Yes this is possible.. you may want to check out some papers relating to this on OTN and on the RAC SIG website at www.oracleracsig.org.
