WAN Fail Over in Duplexed Setup

Hi,
We have a Duplexed setup with Rogger over the WAN and PG's with local Fail-over. Side A is having 2 PG's and Side B is having 3 Pg's. Out of 3 PG one is Dummy PG and made active in Side B. If the WAN Link(Public and Private) go down which Side will be active. Kindly explain.
Thanks,
Gana

Hi Gana,
I know this is 3 years ago that you asked this question, however it could be a live one with others. I myself are searching for a guide on how to setup the dummy pg, but to answer your question.
Side A sees 5 PG's (from both sides). Side A will go active when it sees 50% or more PG's. In this scenario, Side A will be active when seeing 3 PG's. If the WAN link goes down, it will only see 2 PG's and will NOT  be active.
Side A sees 5 PG's as well. Side B will go active when it sees more than 50%. In this scenario, Side B will be active when seeing 3 PG's. If the WAN link goes down, it will only see 3 PG's and will be active.
Hope this clarifies your question you had a long time ago.

  • BGP in Dual Homing setup not failing over correctly

    Hi all,
    we have dual homed BGP connections to our sister company network but the failover testing is failing.
    If i shutdown the WAN interface on the primary router, after about 5 minutes, everything converges and fails over fine.
    But, if i shut the LAN interface down on the primary router, we never regain connectivity to the sister network.
    Our two ASR's have an iBGP relationship  and I can see that after a certain amount of time, the BGP routes with a next hop of the primary router get flushed from BGP and the prefferred exit path is through the secondary router. This bit works OK, but i believe that the return traffic is still attempting to return over the primary link...
    To add to this, we have two inline firewalls on each link which are only performing IPS, no packet filtering.
    Any pointers would be great.
    thanks
    Mario                

    Hi John,
    right... please look at the output below which is the partial BGP table during a link failure...
    10.128.0.0/9 is the problematic summary that still keeps getting advertised out when we do not want it to during a failure....
    now there are prefixes in the BGP table which fall within that large summary address space. But I am sure that they are all routes that are being advertised to us from the eBGP peer...

    i would not expect summary addresses to still be advertised if the specific prefixes are coming from eBGP... am i wrong?
    thanks for everything so far...

    When a user requests to connect to <alias>, sqlnet will attempt to

    You can have as many descriptions in the description_list as needed.
    The client will only receive an error if all the descriptions fail.

  • Front End pool failed over

    Hi all,
    1. I setup a pool with three Front End servers (FQDN of pool is pool.site1.sip96x2.com and it's pointed to IP address of three Front End servers). Everything works fine. But When I disable network interface on FE1 and FE2, the Lync clients are disconnected.
    I haven't understood clearly how the Lync clients failed over in a pool? Please clarify to me.
    2. I have two central site (Root site and Primary site, they have different domain sip96x2.com and site1.sip96x2.com). The simple URL dialin is pointed to Front End server at Root site. So if the link between Root site and Primary site is down, how can the
    users at Primary site connect to dialin URL? 
    3. In building topology for Front End pool, I checked Override FQDN internal web service and the FQDN is "poolint.site1.sip96x2.com". I created three A records "poolint.site1.sip96x2.com" and pointed to three IP addresses of Front End
    servers. Is it right?
    Thanks so much!

    Ah ok, well first thing if I am reading this correctly, pool pairing Standard with Enterprise is not supported. You should only pair Standard with Standard and Enterprise with Enterprise (even though topology builder won't stop you) Take a look here for
    support scenarios http://technet.microsoft.com/en-us/library/jj204697.aspx
    To deal with the simple URLs in the event of failover you need to add them using Powershell. Take a look at this article which explains and gives an example: http://blogs.perficient.com/microsoft/2012/01/configuring-simple-urls-for-multiple-lync-pools/

  • Exception while failing over to 2nd RAC Node

    We are using Weblogic 10.3.4. Our setup is that we have a Web Application (A tapestry front end Web UI) and EJb 2.1 back-end talking to the Oracle database. The EJB’s are CMP. Our product always was just stand alone and it wasn’t until this release we needed to make it work with RAC. To get this to work we followed the model of having a Multidatasource with datasources pointing to our RAC nodes. We have two types of datasources that we use persistent and non-persistent. And we are using the Oracle thin driver – non-XA for RAC Service Instances, supporting global transactions.
    When we do failover to the 2nd node we get a nasty exception in our GUI but after logging out and logging back it we are fine.
    My question is that I assumed I shouldn't have to restart our web-application and it should have stayed up ?? Or is there something wrong with our setup ?
    Thanks,
    Ian

    Showing us the exception and/or the error messages at the server might help...
    Note that failing over does not save any ongoing connection or transaction that
    had been to the dead RAC node... Does your web-app get-use-close JDBC
    connections on a per-user-invoke basis, or does it hold onto connections?

  • After adding 2nd WiSM and failing over AP's some apps don't work

    We have a dual core made up of 2 6513's. In 6513#1 we have WiSM#1 which we have had for sometime now. We have added a 2nd WiSM in 6513#2 for redundancy purposes also we are going to be re-configuring the WiSM in 6513#1 to more match that of the new WiSM in 6513#2. We have installed the new WiSM and failed over the AP's from 6513#1 so we can re-configure it's WiSM. The failover went great and no issues, with the exception that a web application or two didn't function from wireless clients and users were having issues getting to some mapped drives. The only difference from the new WiSM config vs the old WiSM is that on the old WiSM the AP's were in the same VLAN as the controller management interfaces. Now with the new WiSM it's configuration has the controllers AP mgt interfaces ip addresses in a different VLAN from the AP's, we are doing this based on Cisco best practices. If we revert the AP's back to the original WiSM/controllers the PC's where they are on the same vlan/subnet the applications and shares that were having issues the other way work. We have placed a call with Cisco TAC and they say our configs look good and we even sent them some packet captures and they said everything looks normal. The wireless clients can ping and resolve the server hosting the application database just fine.
    Thanks

    We did create the mobility groups, and we are using DHCP opt 43. The AP's find the 2nd WiSM#2 just fine and associate to the controllers and all the WLAN's work just fine. The only issue is that after the AP's are on the new WiSM and controllers there is an application or 2 that is having trouble locating it's database server and that some share's are not working. Again the only difference in this new setup in that now the AP's are on a different subnet/vlan from the controller mgt addresses where as before they were in the same subnet/vlan and the application and shares worked fine. It's almost like it is a bit of a routing issue?
    Thanks

  • How do the application servers connect the new database after failing over from primary DB to standby DB

    How do the application servers connect the new database after failing over from primary DB to standby DB?
    We have setup a DR environment with a standalone Primary server and a standalone Physical Standby server on RHEL Linux 6.4. Now our application team would like to know:
    When the primary DB server is crashed, the standy DB server will takeover the role of primary DB through the DataGuard fast failover. As the applications are connected by the primary DB IP before,currently the physical DB is used as a different IP or listener. If this is happened, they need to stop their application servers and re-configure their connection so the they coonect the new DB server, they cannot tolerate these workaround. 
    Whether does oracle have the better solution for this so that the application can automatically know the role's transition and change to the new IP without re-confige any connection and shutdown their application?
    Oracle support provides us the answer as following:
    ==================================================================
    Applications connected to a primary database can transparently failover to the new primary database upon an Oracle Data Guard role transition. Integration with Fast Application Notification (FAN) provides fast failover for integrated clients.
    After a failover, the broker publishes Fast Application Notification (FAN) events. These FAN events can be used in the following ways:
    Applications can use FAN without programmatic changes if they use one of these Oracle integrated database clients: Oracle Database JDBC, Oracle Database Oracle Call Interface (OCI), and Oracle Data Provider for .NET ( ODP.NET). These clients can be configured for Fast Connection Failover (FCF) to automatically connect to a new primary database after a failover.
    JAVA applications can use FAN programmatically by using the JDBC FAN application programming interface to subscribe to FAN events and to execute event handling actions upon the receipt of an event.
    FAN server-side callouts can be configured on the database tier.
    FAN events are published using Oracle Notification Services (ONS) and Oracle Streams Advanced Queuing (AQ).
    =======================================================================================
    Who has the experience and the related documentation or other solutions? we don't have the concept of about FAN.
    Thank very much in advance.

    Hi mesbeg,
    Thanks alot.
    For example, there is an application JBOSS server connecting the DB, we just added another datasource and put the standby IP into the configuration file except adding a service on DB side like this following:
            <subsystem xmlns="urn:jboss:domain:datasources:1.0">
            <datasources>
                    <datasource jta="false" jndi-name="java:/jdbc/idserverDatasource" pool-name="IDServerDataSource" enabled="true" use-java-context="true">
                        <connection-url>jdbc:oracle:thin:@<primay DB IP>:1521:testdb</connection-url>
                        <connection-url>jdbc:oracle:thin:@<standby DB IP>:1521:testdb</connection-url>
                        <driver>oracle</driver>
                        <pool>
                            <min-pool-size>2</min-pool-size>
                            <max-pool-size>10</max-pool-size>
                            <prefill>true</prefill>
                        </pool>
                        <security>
                            <user-name>TEST_USER</user-name>
                            <password>Password1</password>
                        </security>
                        <validation>
                            <valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.oracle.OracleValidConnectionChecker"/>
                            <validate-on-match>false</validate-on-match>
                            <background-validation>false</background-validation>
                            <use-fast-fail>false</use-fast-fail>
                            <stale-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.oracle.OracleStaleConnectionChecker"/>
                            <exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.oracle.OracleExceptionSorter"/>
                        </validation>
                    </datasource>
                    <drivers>
                        <driver name="oracle" module="com.oracle.jdbc">
                            <xa-datasource-class>oracle.jdbc.OracleDriver</xa-datasource-class>
                        </driver>
                    </drivers>
                </datasources>
            </subsystem>
    If the failover is occurred, the JBOSS will automatically be pointed to the standby DB. Additional actions are not needed.

  • NIC not failing Over in Cluster

    Hi there...I have configured 2 Node cluster with SoFS role...for VM Cluster and HA using Windows Server 2012 Data Center. Current set up is Host Server has 3 NICS (2 with Default Gateway setup (192.x.x.x), 3 NIC is for heartbeat 10.X.X.X). Configured CSV
    (can also see the shortcut in the C:\). Planning to setup few VMs pointing to the disk in the 2 separate storage servers (1 NIC in 192.x.x.x) and also have 2 NIC in 10.x.x.x network. I am able to install VM and point the disk to the share in the cluster volume
    1. 
    I have created 2 VM Switch for 2 separate Host server (using Hyper-V manager). When I test the functionality by taking Node 2, I can see the Disk Owner node is changing to Node 1, but the VM NIC 2 is not failing over automatically to VM NIC 1 (but I can
    see the VM NIC 1 is showing up un-selected in the VM Settings). when I go to the VM Settings > Network Adapter, I get error -
    An Error occurred for resource VM "VM Name". select the "information details" action to view events for this resource. The network adapter is configures to a switch which no longer exists or a resource
    pool that has been deleted or renamed (with configuration error in "Virtual Switch" drop down menu). 
    Can you please let me know any resolution to fix this issue...Hoping to hear from you.
    VT

    Hi,
    From your description “My another thing I would like to test is...I also would like to bring a disk down (right now, I have 2 disk - CSV and one Quorum disk) for that 2 node
    cluster. I was testing by bringing a csv disk down, the VM didnt failover” Are you trying to test the failover cluster now? If so, please refer the following related KB:
    Test the Failover of a Clustered Service or Application
    http://technet.microsoft.com/en-us/library/cc754577.aspx
    Hope this helps.

  • Replication fail-over and reconfiguration

    I would like to get a conversation going on the topic of Replication, I have
    setup replication on several sites using the Netscape / iPlanet 4.x server
    and all has worked fine so far. I now need to produce some documentation and
    testing for replication fail-over for the master. I would like to hear from
    anyone with some experience on promoting a consumer to a supplier. I'm
    looking for the best practice on this issue. Here is what I am thinking,
    please feel free to correct me or add input.
    Disaster recovery plan:
    1.) Select a consumer from the group of read-only replicas
    2.) Change the database from Read-Only to Read-Write
    3.) Delete the replication agreement (in my case I am using a SIR)
    4.) Create a new agreement to reflect the supplier status of the chosen
    replica (again a SIR for me)
    5.) Reinitialize the consumers (Online or LDIF depending on your number of
    entries)
    That is the general plan so far. Other questions and topics might include:
    1.) What to do when the original master comes back online
    2.) DNS round-robin strategies (Hardware assistance, Dynamic DNS, etc)
    3.) General backup and recovery procedures when: 1.) Directory is corrupted
    2.) Link is down / network is partitioned 3.) Disk / server corruption /
    destruction
    Well I hope that is a good basis for getting a discussion going. Feel free
    to email me if you have questions or I can help you with one of your issues.
    Best regards,
    Ray Cormier

    There is no failover in Meta-Directory 5.1, you can implement manual failover on the metaview by using multi-master replication with Directory Server. There are limitations and this is a manual process.

  • DAG Sporadic Entire Server DB Fail Over

    Hi,
    I have been having this issues for a while now, I have two physical exchange servers in a DAG, both on Exchange 2013 CU1. Randomly, every few days and various times, Server1 will fail all of it's databases over to Server2. I'll redistribute them, and again,
    say Server2 will fail all databases to Server1. In short, both servers at times have failed their databases over.
    I started with this: http://technet.microsoft.com/en-us/library/dd351258(v=exchg.150).aspx which led me to setup monitoring of the Microsoft-Exchange-ManagedAvailability logs. I can tell you that replication tests work fine, and the health of all the
    databases are fine.
    My monitoring turned up the following errors, in this example "EX0001" was the server that failed all of it's databases over to "EX0002".  It seems pretty clear to me, that Exchange Managed Availability, is finding an issue with
    EWS, attempting to restart the MSExchangeServicesApp pool and cannot due to "Throttling" so ti fails the DB's over, that's my  best guess...the problem is I dont know how to fix this...I've run through troubleshooting EWS Healthset, nothing
    really turns up... http://technet.microsoft.com/en-us/library/ms.exch.scom.ews.protocol(v=exchg.150).aspx

    Hi,
    Based on the error message, throttling rejected the operation. I recommend you use the Get-ThrottlingPolicy | fl cmdlet to view EWS settings in throttling policy.
    You can modify the default throttling policy and set the basic settings for EWS. Then restart the Microsoft Exchange Throttling service and recycle the MSExchangeServicesAppPool to check the result.
    For more information about the EWS throttling, you can refer to the following articles.

    Hi ,
    It is a 8 node 11.2.0.2 grid infra.
    While pulling both cables from public nic the VIP is not failed over to surviving nodes in 2 nodes but remainng nodes VIP is failed over to surviving node in the same cluster. Please help me on this.

  • Fail-Over?

    Hi,I'm looking into the fail-over solution for our Essbase server. I'm currently looking at EDS's clustering solution. Could you please share your experience with it if any of you as it implemented? Also, I'm wondering if there are anyone who was successful in implementing the unsupported fail-over solution such as MS Clustering or anything else? If you have any unique idea for the fail-over, I'd appreciate it if you could share it with me.Thank you,Tony

    Hi Tony,I believe the EDS solution uses the industry standard J2EE clustering which has wide vendor support and has been around longer (ie more mature).I haven't personally setup J2EE clustering (or the MS clustering either) so I can't offer any personal advice on the topic.Tim TowApplied OLAP, Inc

  • Sun Identity Manger 8.0 and fail over..

    We are setting up a fail/recovery site for our Sun Identity Manager solution, I had pictured a seem less fail over, but that looks near impossible to do with oracle database. I had pictured load balanced Appserver, with load balanced data bases, sort of a multi-master like LDAP allows..
    Curious what others are using for a fail over site / setup.
    Thanks

    We're using 7.0. For us failover is basically mulitple servers all using the same DB repository, with a "smart" loadbalancer in front of them (smart meaning, able to detect which back end servers are responsive).
    IdM doesn't use any inter-server temp-data synchronization, all the servers running off the same repository communicate by committing changes to the database.
    So if a specific IdM instance dies, on the next page load the user will be redirected to a new server. That server will redirect to the login page and ask the user to re-auth, with the desired page placed after login.jsp as a "nextPage" argument. After (re-)logging in, the user's returned to the page they were trying to get to. However, in-progress edits that had not been committed back to the database will be lost.
    We looked at high availability arrangements where valid sessions are shared across a new server, but fundamentally the limitation is that the app servers still don't sync in-progress edits, so the only difference between an HA environment and a more passive fail-over environment (like ours) is that in an HA environment the user doesn't have to re-login on a server failure; they still lose in-progress edits. So HA didn't seem like it added value to us.
    If you are literally talking about an off-site, completely standby, seamless failover site, I agree I don't see how you would do that. I'd expect that you'd need the offsite setup to be a cold-standby site; configured to use the replicated database, but with the apps powered down until you actually need them. Otherwise, I think you'd have problems with the standby site servers not wanting to "standby". You could ensure no users end up on the standby servers, but background processes are likely to be run across both the primary and the standby services; I don't think you can enforce an "idle but running" status for the standby servers.
