Continuity after a failover
Hi, I am new to clustering. 1. If I create a cluster with 2 nodes and shared storage, and keep my application running on node1, client applications will be connecting to my application on node1. In the event of a failover, when the application starts on node2, will the client applications need to change the IP address to which they were connecting? Or will VCS show a single IP address to the external world so that client applications do not need to be reconfigured? 2. Can I configure VCS to start my application on node2 automatically in the event of failover, without any manual intervention? Regards, Yash

Bind Steward to a specific IP
Is it possible to bind Steward to a specific IP? The question arise after we realised in one deployment where the host with Steward has several IPs from the same network was sending Steward responses from different IP from time to time which was not good from the firewall standpoint. Can it be configured to use a specific outgoing IP or it uses bind() to 0.0.0.0 and firewalls should be configured to expect connections from all available IPs? I suspect the latter but just wanted to re-confirm. Documentation for Steward is quite thin and does not go that deep, unfortunately.

Process Agent
Hi all, I have configured SQL service group. I need a restart 1C application server after failover accours. For this purpose I will use script. The script will done 1 time after service group become online. I think process agent can help me. For test and understand how work proces agent I create easy bat script: { echo Hello > File.txt } When I do online for agent I see script is done (file File.txt is created) but the agent do not became online. I think script have to send any variable to VCS that VCS can know started programm is "UP". Do I correct understand situation and if YES what script must return to VCS?

Forward Traffic from VCS virtual IP
Hello Experts, We have a two node active-passive VCS 6.0 cluster running in Solaris LDOM on T4-1 servers. Two virtual interfaces (Vnet0 and Vnet1)are configured from the control domain using igb2/igb4. vnet0 and vnet1 using solaris ipmp. The cluster IP is configured as a virtual IP on top of vnet0 as its comes online as vnet0:1. Out external connectivity must happen only from Cluster virtual IP on vnet01:1, but the network team informed that no traffic coming from cluster vitual IP. The firewall only receives the packets from the host IP which was configured on vnet0. Can anyone tell me , how to configure the VCS to forward the traffic from cluster IP to only a particular destination. We have configured the resources using MutliNICB/IPMultiNICB. Thanks

Oracle Enterprise Manager 12c monitoring of VCS
Hi, If there are any users in the community who wish to trial a plugin for monitoring VCS through Oracle Enterprise Manager 12c, please let me know. I've been working with a number of clients to develop a custom EM 12c plugin to allow transparent integration of VCS targets into the EM framework. Benefits include centralised visbility, out of the box monitoring, direct integration into the EM12c alerting framework and configuration management. More info and screenshots are available at http://www.aidev.uk Any questions, drop an email to info@aidev.uk many thanks, Scott

A question about Oracle DataGuard / DataGuard Broker agent
I'm currently implementing a DR platform for one of our customers as follows: Scenario The platform is composed (currently) of two one-node clusters in a GCO setup 2 IBM POWER 750 LPARs running AIX 6.1 (one per site) Oracle 11g R2 and Data Guard configured (non-RAC) No shared storage VCS 6.0.3 with the latest relevant agents form SORT As of today, the setup works as expected, but the customer requires that we use the DataGuard Broker agent to manage the database replication, to avoid impacting other administration procedures. The problem with that is that the current available version of the AIX agent (5.0.10.0) does not support using the broker agent in a non-RAC configuration, as opposed, for example, to the Solaris version (5.0.14.0), that includes the necessary functionality. Now, the questions are: Why the AIX agent does not currently support DG Broker in non-RAC configuration? Is this functionality on the development roadmap for the agent? If the answer to the previous question is "yes", is there an expected release date for the updated agent? Best regards, Julio.

VVR with Geo-cluster Implementation.
Hello, We are planning to implement a DR solution using VVR for data replication and Geo-cluster for failover. The production side consists of 2 node cluster (2 ldoms) and the DR consist of 1 node cluster (1 ldom). On the production side we have 1 ldom per customer with a single VCSservice group for the customer,whereas some of of the ldoms have several customers in a single cluster with multiple service groups (1 service group per customer). We need the ability to failover a single customer to the DR site. In the case of single ldom or enviorment per customer we can do this easily. My query isin case ofmultiple customers/service groupson the single ldom and in a single VCS cluster, will this cause any limitation or is just case of failing over the service group for the particular customer.

Clustered NFS
Can someone confirm my understanding of CNFS in that clients can acces the same share from different nodes in the CNFS cluster. So for example suppose you have 3 nodes, A, B and C and filesystem "/myshare" which is CFS mounted on all nodes and NFS shared on all nodes, then you could have 3 failover servers each containing a VIP - VIP1, VIP2, VIP3. Then: Client 1 can access /myshare via VIP1 running on Node A Client 2 can access /myshare via VIP2 running on Node B Client 3 can access /myshare via VIP3 running on Node C If node C fails then VIP3 may fail to Node A and then clients 1 and 2 would both be accessing share on Node A, but by different VIPs This is my understanding, but the example in the 5.1 CFS admin guide only shows 1 VIP service group which means in the example, there is no concurrent access of the share which I thought was the point of CNFS, or is the point of CNFS that you don't have to unshare and share when you fail over as shares are always there but there can only be one VIP for the share?

Moving CFS Primary when using SFCFS for fast failover
When using SFCFS for fast failover, so that only one node reads and writes to a filesystem at anyone time and SFCFS is just used to speed up failover by avoiding having to import diskgroups and mount filesystems, there is a requirement to move the CFS primary with the failover application service group so that the application doing the writes is on the same system as the CFS primary. For me this is standard functionality, as SFCFS is particularly sold as a fast failover solution, like as an alternative to Oracle RAC (in addition of course to being able to write to filesystems simultaneously), but I can't find any referece to standard tools for moving the CFS primary in VCS - does anyone know if any exist? For me the most logical approach for this would be to have a trigger script or resource which looks at the CFS service group it is dependent on and promotes the CFSMounts in that child service group which I can write myself, but I would have thought that a standard script/agent exists. Thanks Mike
