Nodes in the cluster of Flex


Hello

can someone explain what are leaf nodes in cluster flex? documentation, I see that they are nodes that do not have access to the storage and they communicate with hub nodes.

Can have the oracle db instances? If yes how data is transferred between the hub and leaf nodes? Through interconnection? It does not overload the interconnection?

Thank you

Soumahoro

The RAC instances are supposed to be present on Hub nodes as they are supposed to be used as DB nodes. This would make the concept of Fusion Cache similar to what we have in previous versions. On the management of the nodes, you must explicitly set, the nodes would be considered to be leaf nodes in the list of the available total nodes.

  • Odd number of nodes in the Cluster controller NSX

    Why odd number of knots are required in the controller NSX Cluster?

    The election of the master for each role requires a vote by a majority of all active and inactive nodes in the cluster. This is the main reason why a Cluster controller must always be deployed based on an odd number of nodes.

    See Page 10-11 of this guide for more information: https://www.vmware.com/files/pdf/products/nsx/vmw-nsx-network-virtualization-design-guide.pdf

  • Error "host cannot communicate with all other nodes in the cluster of enabeld VSAN.

    Hello community,

    We have a problem (?).

    We have a cluster VSAN enabled with four hosts. Everything seems perfect,

    -the configuration is good,

    -Displays the page state VSAN "network status: (green arrow) Normal."

    -Displays the disk management page "status: healthy" for all of our groups of disks.

    -Same 'esxcli vsan cluster get"on each host returns a 'HEALTHY '.

    But we have a yellow exclamation littly on each host 'host cannot communicate with all other nodes in the cluster of enabeld VSAN.

    Anyone with the same problem? Anyone with an idea or a hint?

    Thank you!

    The failed node can be started in exclusive mode, and I'm able to connect to the asm, but of course without disks. When I am trying to mount starts, I get the following:

    What we do not understand why the failed node has different physical block size / logic. Why the oracle on the failed node linux recognize different value? If it was the same thing, no doubt the cluster could start up:

    Thank you for the help

    I have changed accounts.

    We managed to find the reason. First of all, it is a virtual machine. An expert colleague told me to check the hardware of vmware. We managed to find out that there is a difference of ILO to host vmware hardware. Even if the guest OS virtual material seem to be the same, but the difference between the results of operating system host different logical and physical size of block on 2 nodes. This is the reason.

    We had to update the kernel to apply the setting ORACLEASM_USE_LOGICAL_BLOCK_SIZE to repair the block size for clusterware difference. Everyone was puzzled about why, but the most important is the host VMware system in this issue.

    Thanks for the help

    Hello

    Sometimes, we are not able to access ASM for creation of database due to permissions on a file ' Gride_Home/bin/oracle' owner should be like this:

    -rwsr-s - x 1 grid oinstall 152462728 October 12, 2012 /u01/app/11.2.0/grid/bin/oracle

  • Remove the node from the Cluster

    Hello, I followed Metalink Doc-ID 466975.1 vip remains online, but how do I remove vip entrance? I work with 10.2.0.4 version.

    Thanks in advance!

    Looks like the entrance is not excluded from OCR.

    Use crsctl unregister command to remove it from the OCR.

    Also take a backup of the OCR prior to this operation.

    Concerning

  • Is there such a thing as the node master RAC cluster?

    The GI version: 11.2.0.4

    Operating system: Linux/Unix platforms

    Cluster CARS being an ACTIVE configuration / ASSET, is there such a thing as master node in a RAC cluster?

    If there is such a thing as a master node, in a 4-node RAC cluster, how can I find which is the "master" node and why it is called a "master node"?

    Unlike some cluster systems, it is not really a "master node" for Oracle Grid Infrastructure. This link of @rchem to the Uwe Hesse blog entry contain information about a master node but note carefully the specific tasks for this master.

    Oracle clustered systems have resources. Everything is a resource. The listener is a resource. The instance is a resource. A block of data is a resource. Each resource has a master node and that node may be all in the cluster. And resources of the same type can have different masters. If just because Node1 is the master of the resource for blockXYZ does mean that Node1 is the master of the resource for all blocks. BlockABC can have his mastery of the resource on Node2.

    Most people think of a master node like the one that makes decisions for the rest of the cluster. For example, here is a link to a Dell article: http://en.community.dell.com/techcenter/high-performance-computing/w/wiki/hpc-cluster-nodes

    In this article, it says "the General function of the master node must be the mastermind behind the group." However, GI of Oracle cluster doesn't have this concept. There is no a node responsible for the rest of them. All decisions that need to be made are distributed on all nodes of the cluster, piece meal.

  • Windows Server 2003 clustering - latest addition hw to the cluster

    Hello

    I have a two-node Windows Server 2003 the material is HP/ProLiant BL45p G1 and cluster support.  I bought two new HP/ProLiant BL465c g-7 to replace the old servers with.  Is it possible to add new nodes to the cluster and failover of SQL 2000 databases to the new servers and then turn off the old hardware?

    If possible, is there any hunting witches or things that I need to predict from the outset?

    Any help/suggestions/tips would be greatly appreicated.

    Thank you

  • Who decides the surviving node during the detection of split brain?

    How oracle decides which node be deported upon detection of split brain when all nodes have written in the voting record, but unable to check the heart rate through interconnection.

    Ajay

    Hi Ajay,

    the complexity of this depends on the amount of nodes in the cluster and how is isolated (and how), but generally speaking "the cluster creates an invisible group (cohorts) between nodes, which could potentially cause corruption and should be resolved. » Oracle Clusterware manages the "split brain" scenario in putting an end to all nodes in the smallest cohort. "If the cohorts are the same size, the cohort with the smallest number node inside survives." (Cited in Apress - Expert Oracle RAC diagnostic Performance and Tuning by Murali vandenberghe)

  • Load balancing between nodes in a cluster analytic provider service

    Hi all

    -First a bit of background on my architecture. My EMP environment consist of 3 servers Solaris:

    Server1: Foundation Services + APS + EAS WLS Server Admin

    Server2: Foundation Services-APS-EA

    Server 3: Essbase Server + server Essbase Studio

    All services are deployed on a single domain. We have a load balancer, sitting in front of Server1 and Server2 that redirects the request according to the availability of services.

    -Consider the APS:

    We have an APS cluster "AnalyticProviderServices" loaded their AnalyticProviderServices1 on Server1 and AnalyticProviderServices2 deployed on Server2.

    So I connect to the APS and connect as User1. Say that the balancer load decides to send my request to server1, so my request are then managed by APS on Server1. Now if APS on server1 is reduced, all requests for APS on server1 are redirected by weblogic to APS on server2.

    Now ideally APS on server2 should say "hey I see what APS on server1 is down so I will take your session, where it was stopped." So I wait for the 2nd APS node in the cluster to tale my session. But this does not happen... I need to log in again when I hit refresh in excel I get the error "Invalid session...". Please log in again". When I opened EAS, according to me, that I was connected with a new session ID. It seems that the cluster nodes are simply load - swing and are not smart enough to take a node that failed, sessions where she had stopped.

    Is my understanding correct or do I have to configure something to do?

    Thank you

    Kent

    Yes, the session will be lost.

    See you soon

  • Removing servers still have the cluster database and agent status 'pending '.

    Enterprise Manager 12.1.0.2

    We have recently decommissioned 3 servers that were part of a cluster.  Servers and their agents are gone.

    Em, I deleted the nodes in the cluster, removed the hosts and all of its objects.

    A node is gone, two left.

    I have 'cluster of databases' which show the status pending.

    I have 2 principles that show too inaccessible.

    I tried to delete these courses, which all but no luck. Any suggestions?

    This code still works?

    Start

    mgmt_admin.cleanup_agent('agentname:port');   commit;

     -mgmt_admin.delete_target_internal ('agentname', 'official');   commit;

    end;

  • Syntax of use YES to remove a node from the RAC

    Hello

    In reference to the Oracle documentation on the deletion of a node of RAC environment, it showed two syntaxes
    -- syntax one
./runInstaller -updateNodeList ORACLE_HOME=$ORACLE_HOME "CLUSTER_NODES={rac2}" –local

-- syntax two
runInstaller -updateNodeList ORACLE_HOME=$ORACLE_HOME CLUSTER_NODES="" –local
    In one, he used CLUSTER_NODES = "' and the other 'CLUSTER_NODES = {rac2}'"

    They are both correct? Made the CLUSTER_NODES = "" means the current node is affected? "

    Thanks in advance.

    to remove a node, follow the steps

    1 remove ASM Instance
    srvctl stop asm - n
    srvctl remove asm - n
    RM - r $ORACLE__BASE/adfflin / + ASM
    RM - r $0RACLEJOME/dbs / * ASM *.

    Finally, delete all the entries in the/etc/oratab ASM. These entries have the prefix + ASM

    perform the backup of your rock when you have completed this
    operating mode.

    2 remove the listening process
    As the Oracle user, on any node in the cluster, run the netca

    On the Configuration page, select the Cluster configuration and click next to open the Active
    Nodes page.

    On the page of the active nodes, select the node that you want to remove and click next to display the home
    page.

    On the homepage, select listener configuration and click next to open the page of the listener.

    On the page of receiver, this time select Remove and click next to open the Select listening port page.

    On the Select listening port page, specify the listener to remove.

    The NETCA will stop the listener daemon and remove the content of $TNS_ADMIN/listener. ORA

    3 remove the software from Oracle database

    On the node that you remove, log in as user oracle and

    come on in ' cd $ORACLE_HOME/Yes/bin '.
