VCS Cluster configuration

• VCS CLUSTER PROBLEM

  Need an idea to fix a few alarms on my cluster configuration two VCS.

  VCS are running X8.5.1

  Had five alarms on the my resume

  1. the replication is no longer available.  Systems have 4ms between them.

  2 lost all Admin user accounts less?   Strange... Newspapers reported that no one was in the VCS

  3. admin VCS Master on the master account was returned to the TANDBERG default?   (Alarm has stated that this was the case).

  Changed the admin password and recreated my admin on the master account.

  4 approves. it 2 (slave) lost all VCS user account, but the admin password reset not and does not have that I have listed.

  My partner has been able to connect to the peer 2 VCS, even if his account is not listed in the list of users?

  ------------------------------------------------------------------------------

  After the captain restart now, I have three alarms

  a. unexpected software error has been detected in ClusterDB: unknown reason on the slave?

  b. There is a port conflict between the media (36000-47999) port range and the range of ports UDP ephermeral (40000-49999) on Master

  c. Core dump mode has been changed, but a reboot is required before this takes effect on Master

  1. any ideas what could have caused the user accounts to disappear on the page?  I think that they are still in the VCS configured just cannot see them.

  2 will be restarting on the master clear alarms b and c?

  3. a reboot on the peer 2 (slave) would open the ClusterDB alarm?

  I can't restart until later tonight that calls are up on both.

  Oh finally where one or even any changes a core dump mode?

  Thank you

  Connect to the VCS via Telnet/SSH/series and log in as 'root '.

  use the command 'selectsw' to see what partition software he's using now, then, if image1 is active, allows the command "selectsw image2" switch to the other, or vice versa, and then restart your computer.

• VCS Cluster DNS problems

  Hello

  I have created a DNS SRV to configure in the FULL of the VCS Cluster domain name.

  The problem is when devices try to enroll in the VCS Cluster; I put in the endpoints, in Gatekeeper registration DNS or IP address of the DNS SRV but the always end points will never reach the cluster of VCS.

  I check the logs in DNS SRV and I don't see any request from devices.

  I think I need to create a virtual IP address with DNS with load balancing, I mean: IP/DNS (FQDN) for the Cluster with load and balance when devices trying to connect to the cluster's IP/DNS it transmits the request to an IP or host name of a host in the cluster.

  23.1.0.201 (vcs.xxx)

  The peer of the cluster:

  23.1.0.32 (vcscontroltc.xxx) Master

  23.1.0.33 (vcscontrolvag.xxx) slave

  XXX--> field

  Is this right?

  Thanks in advance.

  Best regards.

  Hello

  then 23.1.0.201 is the IP address of your DNS server?

  How you need to configure is:

  FULL of the cluster domain name: vcscluster.domain.local

  VCS counterpart A: vcscontroltc.domain.local

  VCS counterpart B: vcscontrolvag.domain.local

  With the above assumptions, that's what you create in DNS:

  -For the FULL domain name cluster, create two A records for vcscluster.domain.local one pointing to 23.1.0.32 and the other pointing to 23.1.0.33. With that, I recommend that you enable alternate on your DNS server.

  -For each peer, create a record, so vcscontroltc.domain.local points to the points 23.1.0.32 and vcscontrolvag.domain.local to 23.0.1.33.

  -Create SRV H323 and SIP records for vcscluster.domain.local. With that, I recommend that you create two SRV records for each service, pointing A Exchange and showing a B counterpart, with a weight and priority. For example:

  _sips._tcp.vcscluster.domain.local-> vcscontroltc.domain.local, priority 1, weight 50

  _sips._tcp.vcscluster.domain.local-> vcscontrolvag.domain.local, priority 1, weight 50

  If you follow the advice above, you should be able to configure all of your interior SIP and H323 endpoints with a h.323 gatekeeper address/SIP proxy address, of vcscluster.domain.local and endpoints must enroll in one of the peers, regardless of whether endpoints supports DNS SRV.

  If the domain that you use is public, you also want to add the SRV records for that domain name. These SRV records must point to your VCS Expressway, to ensure that incoming calls from URI function as it should. For example:

  _sips._tcp.domain.local-> vcse.domain.local, priority 1, weight 100

  If you have several VCS-E you can adjust the SRV records accordingly.

  Hope this helps,

• State of VCS cluster?

  can someone explain the status of vcs on a cluster configuration?

  My question is if the condition of the assets must be crossed between peers?, or there must be a single vcs active on the cluster?

  Please your help

  PS: version 7.1 of the vcs

  Peer 1 master:

  

  counterpart 2

  

  Thank you very much

  Hello Cristian,

  This looks ok. On the master, it will show the peer as active whice means that the peer is accessible... and even homologous way it shows control as active who once again even an indication that she is available.

  If you restart any server, and then refresh the page... Then it will show uknown or unreachanble or failed.

  imprtant part lies on the State of the cluster when you scroll down... It should show success and show you the next time both resync.

  Thank you

• VCS Cluster - record H.323

  Hi all

  We have a VS Cluster and would like to register 2 MCU´s and a gateway with H.323 on it.

  -Inscription on the first not peer very well - no prob. record of 2. Peer - does not (source unauthenticated received fron)

  VCS Trace... no this crypto token / / invalid cryptographic tokens.

  Its allways happened on 2. peer.

  Restart the MCU, restart Cluster, see time servers, disabling / enabling H.323 in VCS and MCU - all done, always the same failure.

  VCS Cluster / MCU / ISDN are all in the same subnet, but in another location. RTD between the location is less than 10 ms.

  BTW: SIP with tls runs without any risks.

  Does anyone have an idea?

  Thank you much for your helping hands

  /Dirk

  In general this should not happen.

  You said you checked the time servers, but have you also checked the actual time on the

  VCS and the endpoint? (for example the login as root and check with the date).

  Try to use the same NTP server on all VCS and endpoints.

  Is the group itself ok (see configuration / clustering)?

  Something not ok with the zone configurations?

  You have any local specific or server based CPLs on VCS?

  No matter what firewall/nat/alg between VCS and the endpoint?

  Do you have a xconfig on two VCS and compare the config of the differences?

  Your sure it's the right vcs you hit?

  Do you still review log files and compare what's happening the first relative to each other?

  A tcpdump and check on the VCS of debugging can be interesting as well.

  Please remember useful frequency responses and identify useful or correct answers.

• Question about unique to the VCS cluster driver

  I'm just configuration conductor for the first time according to the guide found here:

  http://www.Cisco.com/c/dam/en/us/TD/docs/Telepresence/infrastructure/con...

  Because I need to connect to a VCS cluster with two counterparts, each counterpart must be configured as a separate with its own appointment IP address location, (in which case I guess I would add two IPs Rendezvous in the nearby area of VCS Configuration) or should I point to the VCS Cluster FULL domain name and I have an IP to unique appointment for all of the VCS cluster?

  I can't see anything in the guide on this subject...

  Thanks in advance!

  Hi Nick,

  Unique location pointing to the VCS cluster FQDN.  You are right the guide lacks details, will focus on opening a defect in the documentation for this.

• Highway VCS cluster

  Hello

  We intend to deploy VCS Cluster consisting of two expressway Expressway.  The two highway will be activated with Dual Interface. Need some clarification regarding the ip and dns address. Here is an example of setting.

  for example

  Highway of VCS A: 192.168.10.2 for the first interface.   192,168.20.2 assigned to the second interface and nattted to 77.100.42.23

  Highway of VCS B: 192.168.10.3 assigned to the first interface. 192.168.20.3 assigned to second iinterface and natted to 77.100.42.24

  name of the cluster: video.exampledomain.com

  FULL domain name: video.exampledomain.com will be be mapped both the public ip address 77.100.42.23 and 77.100.42.24 with the required SRV records.

  When customer movi connect to video, exampledomain.com traffic will be routed to 77.100.42.23 and 77.100.42.24 in "round robin" mode.

  Well confirm the above is the correct way to deployment and what will happen if A vcsexpressway is down. always the first call will fail because the rqurest will be sent to 77.100.42.23 and the second appeal attempt will succeed.

  Krishna.

  Hello Krishna,

  your deployment plan looks good, assuming that 192.168.10.x and 192.168.20.x are different subnets. Please be sure to set up clustering on LAN1 (the interface non-translated) which seems to be part of your plan.

  Concerning the behavior of call when one of the VCS is down, assuming that your SRV records were properly implemented and that the remote caller has good DNS SRV support for its implementation H323 and SIP, the appealing party must switch to VCS work in case of failure of the initial connection to the slaughtered VCS. In any case the result will depend greatly on the conduct of the appellant and his ability to switch to other VCS during his attempt to connect through the slaughtered VCS fails.

  Hope this helps,

• Maximum non-traversal calls from VCS Cluster

  Hi all

  As mentioned in the CV data sheet, I know that a VCS can accommodate up to 500 calls from nontraversal.

  But VCS cluster which consists of 6 VCS can treat 2,000, steps 3 000 (6 x 500).

  I wonder how many calls each VCS cluster can handle.

  Is this correct?

  2 VCS cluster

  => Registratrions up to 5,000?

  Up to 1,000 calls in nontraversal?

  Up to 200 calls course?

  VCS cluster 3

  => Registratrions to 7 500?

  Up to 1,500 calls to nontraversal?

  Up to 200 calls course?

  4 VCS cluster

  => Registratrions up to 10,000?

  Up to 2,000 calls in nontraversal?

  Up to 300 calls course?

  5 VCS cluster

  => Registratrions up to 10,000?

  Up to 2,000 calls in nontraversal?

  Up to 400 calls course?

  6 VCS cluster

  => Up to 10 000 registratrions

  Up to 2,000 calls from nontraversal

  Up to 400 calls course

  Hi Kotaro,

  even if the 6 servers are taken in charge by vcs cluster however only 4 will be active. So 4 * 500 is 2000 license.

• Status of VCS Cluster through CLI

  Hello

  Is it possible to check the status of the Cluster of CLI VCS Cluster?

  I have found that a single command:

  XStatus external 1 Applications

  * Applications (s):

  1 external:

  Status:

  ClusterStatus:

  ClusterState: "enabled."

  ClusterLastSyncDate: '2013-04-02 08:39:19.

  ClusterNextSyncDate: '2013-04-02 08:40:19.

  ClusterLastSyncResult: "SUCCESSFUL."

  * s/end

  Ok

  But if I disconnect one of the peers of the bunch, fruit of xstatus external 1 Applications is the same.

  Is it possible to check the status of the Cluster via CLI database?

  -What happens when the cluster breaks down?

  -What command can I use to check the status of the Cluster, Cluster database state, the State of the communication with other peers? What are the States of possible failure?

  Thanx.

  Marek.

  Do not find them as documented, so use at your own risk :-)

  In any case, I like web access https better for information of status and then to misuse the root account.

  Create an account with api read access and get:

  https:///api/management/status/clusterpeer

  the output may differ with different versions

  (that one was a X6.1 but X6.1 seem to show that the other peers see as well)

  [{"peer":"192.168.0.91","num_recs":2,"records":[{"uuid":"54c4b972-0d5f-4748-90f6-3203d5eae693","peer":"192.168.0.91","state":"up"},{"uuid":"8939f6d5-77d8-4ec0-b275-19cd95b905d5","peer":"192.168.0.90","state":"up"}]}]

• VCS 'OLD' device and device New VCS cluster "(CE500)" ""

  Hello.

  An easy question, can you do a VCS cluster between the 'old' and the 'new' device? is there a limitation?

  In the prerequisites, I saw some VM 8 hearts, but do not understand a lot.

  Thancks! An optimal day

  Hello Alex.

  As long as the VCS platform is the same (physical or virtual) and running the same versions of software and complete you the prerequisites.  See Maintenance and creation of VCS Cluster Deployment Guide for more information.

  The part on the cores is related to your virtual deployments, so if you use virtual VCS, he wants to make sure that you use the same size of deployment noticed on pg 4 of the installation Guide for the VCS VM.  You don't have to worry about this with the hardware appliance.

• Help on consistency + Weblogic Cluster configuration

  Hello
  
  I am new to consistency. I explore the consistency to fill one of my condition.
  
  My needs: I have an application deployed on a clustered server logical Web environment. I need to cache data specific to the application (java card) and that should be available to all nodes in the cluster WLS. Application that are cached, data can be updated from any of the node in the cluster WLS and updated the application cache data should be available for all the nodes in the cluster WLS. The nodes in the cluster of WLS resides in different machines from different places.
  
  Can I use coherence as a services of caching for my requirement?
  
  If Yes, do I need to start a server cache consistency on each node of the cluster WLS?
  
  If so, do I need to specially configure these servers cache, so that these cache servers would communicate each other in case of updates of data in the cache?
  
  It will be very helpful if you could also provide sample configurations to achieve the above scenarios.
  
  Thanks in advance!
  
  Kind regards
  Srinivas M

  You can start a cache server in the network by using for example

  # home directory
  BEA_HOME="/home/oracle/bea"
  export BEA_HOME
  # java vendor (for example Oracle or Sun)
  JAVA_VENDOR="Oracle"
  export JAVA_VENDOR
  # cache server klasse
  CACHE_SERVER_CLASS="com.tangosol.net.DefaultCacheServer"
  export CACHE_SERVER_CLASS
  # coherence options
  COHERENCE_OPTIONS="-Dtangosol.coherence.management=all"
  export COHERENCE_OPTIONS
  COHERENCE_OPTIONS="${COHERENCE_OPTIONS} -Dtangosol.coherence.management.remote=true"
  #COHERENCE_OPTIONS="${COHERENCE_OPTIONS} -Dtangosol.coherence.cacheconfig=WEB-INF/classes/session-cache-config.xml"
  #COHERENCE_OPTIONS="${COHERENCE_OPTIONS} -Dtangosol.coherence.session.localstorage=true"
  
  WL_HOME="${BEA_HOME}/wlserver_10.3"
  export WL_HOME
  BEA_JAVA_HOME="${BEA_HOME}/jrockit_160_05_R27.6.2-20"
  export BEA_JAVA_HOME
  SUN_JAVA_HOME="${BEA_HOME}/jdk160_11"
  export SUN_JAVA_HOME
  
  if [ "${JAVA_VENDOR}" = "Oracle" ]; then
       JAVA_HOME="${BEA_JAVA_HOME}"
       export JAVA_HOME
       MEM_ARGS="-jrockit -Xms512m -Xmx512m -Xss128k -Xgcprio:throughput"
       export MEM_ARGS
  fi
  
  if [ "${JAVA_VENDOR}" = "Sun" ]; then
       JAVA_HOME="${SUN_JAVA_HOME}"
       export JAVA_HOME
       MEM_ARGS="-server -Xmx512m -Xms512m -Xmn256m -Xss128k -XX:PermSize=128m -XX:MaxPermSize=128m -XX:+UseParallelGC -XX:ParallelGCThreads=2 -XX:+UseParallelOldGC -XX:+AggressiveOpts -XX:+UseBiasedLocking"
       export MEM_ARGS
  fi
  
  # classpath for the cache server
  CLASSPATH="${WL_HOME}/coherence/coherence.jar"
  export CLASSPATH
  
  # start the cache server
  ${JAVA_HOME}/bin/java ${MEM_ARGS} ${COHERENCE_OPTIONS} ${CACHE_SERVER_CLASS}
  

  -Dtangosol.coherence.management = all option gives made you some useful information about what the cache by using for example the browser mbean provided by jconsole or jrockit mission control.

  You can create an application in which you create a cache, below is an example of a servlet

  import com.tangosol.net.CacheFactory;
  import com.tangosol.net.NamedCache;
  
  import javax.servlet.ServletException;
  import javax.servlet.http.HttpServlet;
  import javax.servlet.http.HttpServletRequest;
  import javax.servlet.http.HttpServletResponse;
  import java.io.IOException;
  import java.util.Random;
  
  public class TestServlet extends HttpServlet {
  
      private NamedCache movies;
  
      public void init() throws ServletException {
          movies = CacheFactory.getCache("repl-movies");
          movies.put(10, new Movie(10, "Rear Window", "Alfred Hitchcock"));
          movies.put(20, new Movie(20, "Vertigo", "Alfred Hitchcock"));
          movies.put(30, new Movie(30, "Double Indemnity", "Billy Wilder"));
          movies.put(40, new Movie(40, "Touch of Evil", "Orson Welles"));
      }
  
      protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
          Integer[] integers = {10, 20, 30, 40};
          Random random = new Random();
          while (true) {
              movies.get(integers[random.nextInt(4)]);
          }
      }
  }
  

  Package the servlet into such a WAR file and deploy it in a WebLogic cluster configured.

  By accessing the servlet on the different nodes in the cluster a new cache is created and added to the
  already running DefaultServer.

  The most difficult part is to configure your cache. As you can see in servlet initialization we EU something like CacheFactory.getCache ("repl-movies");
  Lack of consistency with some configurations of cache example that are contained in the coherence.jar (coherence-cache-config. (XML).
  The following entry is used

  
        repl-*
        example-replicated
  
  
        example-replicated
        ReplicatedCache
        
          
            unlimited-backing-map
          
        
        true
  
  

  A replicated cache is probably what you need as well. You like all the data available on all nodes. If you want to use
  your own cache configuration, you can add the option - Dtangosol.coherence.cacheconfig (see the for the default server startup script)

  A good introduction on coherence can be found here:
  http://www.packtpub.com/article/installing-coherence-3.5-and-accessing-the-data-grid-1

• Is ASM cluster configuration, possible to detail all cluster hosts

  In the case of configuration in cluster of ASM (where its possible to create one ASM DiskGroup is shared between all hosts in the cluster) is it possible to obtain information on all hosts (cluster node) (which are part of this cluster configuration) one machine.
  
  For example. If we have three nodes Node1, Node2, and Node3 configured using ASM cluster (i.e. default ASM instance will be ASM2 ASM1, and + ASM3 on these machine) and then I create multiple starts (some shared between all three nodes and bit limited to single node or two) using a set of SAN disk visible to all.
  In such a scenario, can I get the details of Node2 and Node3 comes to log in Node1 (i.e. Since one machine one single node part of ASM cluster configuration, I need information of all other machines/nodes).
  
  Is this possible? If so, some tips on the way which will be a great help.
  
  ~ Stéphane.

  Hi stephane,

  Maybe I'm missing something here, or I'm too detailed, but depending on how General should be your script, there are some steps, you must check to avoid the false assumptions - e.g., as here: "+ to get the CRS_HOME, I can grep for crsd.bin. If I don't get this running process, this means that configurations is a StandAlone OracleDB and turns to the ASM, ASM is too stand-alone instance. + »

  If you can't find the crsd.bin running, it could also mean that it will not turn now - for some reason any. If you find a DSO running instance, but not crsd.bin, Yes, you can generally assume that you would have a configuration of ASM nonclustered (autonomous), unless you run into a BUG / failure.

  Therefore, it might be a good idea to check the existence / first configuration, then to the current process. For example:

  IF you have installed Oracle Clusterware, you will find an init.cssd under /etc/init.d (for Linux, similar directories for other OS). Therefore, check first for the operating system, if you have the OS specific scripts, then just check for the init.cssd init directory.

  The advantages of checking the init.cssd are: you will get the Oracle Clusterware House - it is set as a variable:
  = ORA_CRS_HOME / ora/clusterware AND you usually get the Oracle user: ORACLE_USER = oracle

  Then you can check if Clusterware is running. You will have more than one way to do it now. You can use ps - ef or you can use Clusterware orders as crsctl check CRS or things of that kind.

  Of some people could argue that there is a DSMB for ASM in standalone (non-cluster) ASM facilities running and there is therefore an init.cssd. YES, but this init.cssd shouldn't be in init in this case - see the comment in the header of the script init.cssd: "In a local, nonclustered, installation without CARS, it must be placed in a directory rcX.d".

  However, just to be safe, you can always check whether or not you will find init.crsd, init.evmd, which are very strong indicators that Clusterware has been installed on the system, unless it was not uninstalled properly...

  Once you've found the Clusterware installed, running AND you know the path to the House - it's easy:

  As said previously, you can use olsnodes to get the nodes in the cluster. You can still use crs_stat. It will tell you the ASM / RAC, the instance number and this node the instance number is running on:

  Name = ora.myrac1.ASM1.asm
  TYPE = application
  TARGET = ONLINE
  STATUS = online on pmrac1

  As for CARS DB instances:

  Name = ora.myrac.myrac1.inst
  TYPE = application
  TARGET = ONLINE
  STATUS = online on pmrac1

  To determine which is the node that you are running your script on: host name must do.

  Of course, all this will work only IF you have installed Clusterware. For environments not clustered, you must work with the ps - ef command, sqlplus and oratab file as you mentioned below, which makes it a bit more complicated. We could predict that's SO so OTHERWISE in your script - IF cluster, THEN do foo, otherwise do BLAH. Just an idea.

  For this question:
  Belongs to ASM cluster - (yes/no)
  (If crsd.bin is running, ASM is clustered. Can this method be invoked always?)

  IF you have a cluster installed, ASM should be part - is the default and recommendation. However, you can run in a broken configuration. You want to guess in your script and secure?

  Just a few random ideas. Thank you

• VCS Cluster question

  Hey all,.

  We have two VCS highways in a cluster.  A VCS is on a tour of the Internet and the other is on a circuit separate from another provider.  The Internet provider for one sucks VCS for video, its only necessary as a backup circuit.  I put this VCS in maintenance mode until the circuit feeding the other VCS fails?  In this way, all records are forced to the VCS with the best circuit of the Internet.

  If a VCS is in maintenance mode, will always be synchronized across the cluster?

  Thank you

  Justin-

  I went forward a sale of our peers CV in maintenance mode earlier today to work around a problem, and it is always on at this point.  Check the page clustering on the mask of the VCS, it shows that the peer is still active.  Having the status of the replication of successful, even up to present any minute.  It seems that everything is going well, but like you if it would be good to hear from someone official.  Even if we force a counterpart basically be in a passive state until get us out maintenance ourselves to become active.  Unlike a cluster of 6 peers where the last two automatically become active when one of the 4 main counterparts breaks down.

• Transmission of events when Cluster configured

• Move cluster configured with replication SRM and Vsphere

  All,

  We go 2 groups in the near future to achieve a geographical distance between the 2 sites.

  A cluster is equipped with VMware 5.0 replication SRM and vSphere and the other cluster running VMware 5.5 and SRM in combination with replication of vSphere.

  What is the best way to move these clusters, I must stop the replication or interrupt the replication process and are these action to perform on SRM or we need to perform any action on the virtual machine itself?

  I read that a stop is setting the State to not configured including destroy all files in the target directory.

  Does anyone have an experience by physically moving a cluster managed by SRM (and replication of vSphere)

  Any help is welcome

  Thank you
