Uprading deployed Cluster from Ipv4 to Ipv6

Hi Friends,
i have already running and deployed a windows cluster for my SQL 2008 and Exchange 2010 Dag in different servers with ipv4 however the company management decided that we have to upgrade all servers connection from ipv4 to ipv6.
as you know that when we create a cluster it also create a virtual connection for connecting users in my case its created with ipv4.
now how am i suppose to change that virtual connection from ipv4 to ipv6 in windows 2008 R2 clustering i mean overall how to achieve my target without destroying anything.
please advise.
thanks greenman

Hi GreeMann,
Start with Windows Server 2008 IPv6 using in the Cluster service will support this functionality as well. This includes being able to support IPv6 IP address resources
and IPv4 IP address resources either alone or in combination in a failover cluster.
Failover clustering also supports 6-4 and Intra-site Automatic Tunneling Addressing Protocol (ISATAP). Additionally, failover clustering supports only IPv6 addresses that
allow for dynamic registration in Domain Name System (DNS) (AAAA host records and the IP6.ARPA reverse look-up zone). Currently, there are three types of IPv6 address types: global, site local, and link local. Dynamic DNS registrations will not occur for link
local addresses and therefore cannot be used in a failover cluster.
But there have some
application has the limited IPv6 support or full IPv6 support, the Exchange Server 2010 has the limited IPv6 support and general speaking, IPV6 is supported for SQL server 2005,2008,2008r2 and SQL 2012, the detail supported
service you can refer the following KB:

Migrate UAG internal adapter from IPv4 to IPv6

I have DirectAccess running successfully for a couple of years now.
However, we now need to migrate our servers from IPv4 to IPv6 (will run side by side). The IPv6 range is a /48 range we received from our ISP
The internal interface of our DA UAG server will also get a IPv6 address. After that DA needs to be reconfigured with the new internal IPv6 interface and a client range for IP-HTTPS and NAT64/DNS64 needs to be specified.
The question is, what will happen with the laptops that are outside of the LAN and don't come inside for new domain policies? Will they reconnect with the new settings or will they loose connectivity? Do they get the new IPv6 routes for the tunnel
adapters?

HELP : Convert socket programming from Ipv4 to IPv6

Hi all,
I need help in converting my Ipv4 socket programing to Ipv6. How can I do this? I already have an Ipv4 socket programming that is working but when I tried to convert it to Ipv6 it doesn't work .
this is my Ipv4 socket programming :
DatagramPacket sendPacket;
DatagramSocket sock;
ip = jtfDIP.getText().trim();
try{
sock = new DatagramSocket();
add = InetAddress.getByName(ip);
sendPacket = new DatagramPacket(buf,buf.length,add,port);
Please help me. How can I convert this to Ipv6. Thank you.

Socket sock = new Socket("host");
or
Socket sock = new Socket("192.168.1.1");
or
Socket sock = new Socket("www.host.com");
or
Socket sock = new Socket("hhhh.hhhh.hhhh.hhhh");
Get it? Just use whatever host, domain name, or IP you need, the underlying native code does the work - you'll never need to do anything, for the most part.

MPLS migration from IPv4 and IPv6

                   Hello,
i have existing MPLS VPN setup using IPv4 between all devices (P,PE,CPE), i want to start to migrate to IPv6 but i want to start the migration for one link between P and PE and all other devices will be the same (IPv4). Can you please tell me how i can acheive this scenario without impcat the services because is life.
Thanks

Accessing JMS UDD deployed on OSB cluster from a composite JMS adapter deployed on soa cluster

Our environment setup
Single domain with three clusters
osb_cluster.soa_cluster and bam_cluster
osb_cluster: osb_server1 and osb_server2
wlsbJMSServer_auto_1: targetted to osb_server1
wlsbJMSServer_auto_2: targetted to osb_server2
osb_subdeployment1:targetted to wlsbJMSServer_auto_1 and wlsbJMSServer_auto_2 JMS servers
osb_subdeployment1 has JMS UDD queue jms/wlsb/queue
soa_cluster: soa_server1 and soa_server2
There is a BPEL composite deployed to soa_cluster. It has JMS adapter trying to read messages from jms/wlsb/queue
JCA JMSAdapter is deployed to osb,soa clusters and Admin server
ConnectionFactory is targetted to soa and osb clusters (osb_cluster and soa_cluster)
We have bounced soa and osb servers(not admin) after jms changes.
soa log says
JMSAdapter Composite1l JmsDDEndpoint_onFailure: Unable to resolve 'jms.wlsb.queue. Resolved 'jms'
Can we access JMS destinations deployed on one cluster from different cluster?
If yes, how can we do that ? do we need to modify BPEL JCA file to indicate destination is on another cluster?
Thanks,
Praveen

Anybody has faced similar issue?

IPv4 to IPv6 RDP Access

Hi;
In our ınfrastructure we use dual-stack. We configured our cluster firewall and router (BGPv6).
Now we have an application server whichs 's run only over IPv6 address. We want to connect this server over RDP service from our edge sites which's run on IPv4 public address. Is it possible ? If possible what we're supposed to do ?
Best regards
Umut

If your firewall has NAT46 capability it is possible, but of all the possible NAT things you can try, that direction is the ugliest. The "right" answer is to dual-stack the edge networks, but that is presumably a long-run solution for you, not a short run one. I don't think RDP embeds IPv4 addresses in the content, so it can probably work. In general, doing protocol translation between IPv4 and IPv6 in either direction on things that aren't simple 1:1 TCP connections is a bad idea.

IPv4 to IPv6 transition thesis

             Hi,
I'm doing Bachelor thesis, the subject is :"IPv4 to IPv6 Transition". I hope you give me titles of books you recommend.
Also,I'd be happy if you give me a few tips.
right now,i need a topology for each transition mechansim with the configuration commands .
and how to configure an IPv4/IPv6 host?
i've already finished CCNA exploration 1 and 2,and now i'm enrolled in a CCNA exploration 3 class.my instructor has not been trained yet on using IPv6 . so,the whole subject is new for me
i'm sorry if this message was badly written , because i'm not that good in english.
yours faithfully,

You might consider the RFC series.
We have been thinking about what we originally called "IP Next Generation" and then called "IPv6" and the requirements for a transition for about 20 years. When we started, we thought about requirements, and over time we have described methodologies and experience with those methodologies. There is ongoing work, primarily in the IETF's IPv6 Operations Working Group (). The current "received wisdom" is probably summarized in RFCs 4213 (
http://www.ietf.org/rfc/rfc4213.txt) and 6180 (http://www.ietf.org/rfc/rfc6180.txt).
Walking through that history means walking through the following. Note that many of these are pretty old, and have been replaced or updated by other documents.

Error while deploying project from BCC

Hi Experts,
I am trying to deploy a project from BCC. While deploying i'm getting following error.
CONTAINER:atg.process.ProcessException; SOURCE:atg.epub.project.AssetLockException: Failed to approve the project TRE-2013413193927 (id: prj550001) for deployment. Unable to obtain exclusive locks to one or more assets. Use the Lock Conflicts page to determine which assets are locked by other projects.
I checked lock assets, but there was no assets.
Can any one help me to resolve this issue..
Thanks & Regards,
Murali

In previous project we deployed same assets, but we deleted that project from DB(tables). Now there is no project with these assets.Probably you deleted the project which was not completed and so it might have been holding some asset locks. You might want to check the corresponding data in avm_asset_lock table in CA schema. Look out for the data corresponding to project's workspace-id in this table, clear that and then try to resume your deployment.
"/atg/commerce/catalog/ProductCatalog" is configured for deployment to this target by another Content Administration cluster named "DEV_ENV". You must ensure that only one Content Administration cluster is responsible for each repository in a given target. Looks that something is mixed up in your deployment topology. May be it was deleted and reinitialized without clearing previous cluster data. Go to /atg/epub/DeploymentAgent in dyn/admin component browser and check the details like: agent's deployment state, deployment mode, current live data store, cluster status etc. Try removing stale cluster from DeploymentAgent using the delete option provided there. Also remove stale cluster data from Publishing Web agent (if present) by navigating to <ATG>/home/PublishingWebAgent/data and deleting a file which might be there with a name like cluster-stat-oldCluster.

What is correct method to deploy cluster aware technology using HA VMs?

Dear all,
I recently had experience creating Hyper-V Server 2012 cluster. This allows for deploying a highly available virtual machine. That's fine. The business machine (virtual machine) becomes highly available. This includes an existing VM enabled to be highly
available or a new VM installed into cluster from scratch.
On the other hand; we have cluster aware applications (SQL Server, SCVMM etc.) which are installed in clustered OS (Windows 2008 R2 Enterprise edition which has failover clustering service) .
Just for clearing concept; what is correct way of deploying a cluster aware technology (SQL Server, SCVMM) in the scenario where the underlying OS; running in VM(s) can be made highly available.
Method 1:
Create simple non clustered VM, install cluster aware application (SQL Server e.g.). Make this VM highly available using Hyper-V cluster. (This seems to be clustering the VM running cluster aware application, not the cluster ware application; which
requires clustering.)
Method 2:
Create HA-enabled VM onto Hyper-V Servers cluster; install cluster aware application within this HA-enabled VM. (This again; the underlying OS/VM is clustered first, the cluster aware application (SQL server or others) how would it leverage
the cluster?)
Please shed light on what is correct method. In both cases it seems the VM running the cluster aware application; is made highly available; meaning leveraging clustering. What about clustering the application
itself? The objective is to be able to not only make the VM highly available; but also deploy clustered SQL Server or other cluster aware technology using such HA VM.

Shahzad.

With SQL Server both M1 and M2 are by far the best solutions. See guest VM cluster is non-optimal as SQL Server works better with own clustering features (AlwaysOn, see link below). And HA would make VM re-boot on another physical host so there would be
both downtime and potential data loss. Run SQL Server in a pair of VMs on a different physical hosts, configue AlwaysOn (use failover SMB share as a witness) and you'll be fine. See:

EA4500 loses IPv4 and IPv6 information

No changes made but router will lose all information for IPv connectivity. I have paid twice to support to fix this issue and it still occurs every few months.
I tried rebooting router, and doing an IP Release/ Renew and router does not get IP address. I'd prefer not to have to pay again to fix this router. Any ideas?

Sorry - thought I had info:
I don't see anything on the router indicating a model other than EA4500. There is a serial number. Its plugged directly into a
Toshiba PCX2500 modem. If I connect my PC directly to the modem I have internet.
The router maintains all settings that Cisco helped me set up before except there are not IPv4 or IPv6 settings. I have screen shots from the setup. The Cisco rep had to clone the MAC of the modem to get the router to work. (Admin tab).
I unplugged modem and router and rebooted each. Everything appears to come up normally except for no IPv4/6 settings. I tried a release/renew but those settings stay blank.
I have internal network connectivity with the router, just no internet. I use Road Runner. I have a second network also on Road Runner but on a different modum and domain that is working fine. Unfortunately I have hard wired connections and kids games that rely on the EA4500

IPv4 vs IPv6 comparison

hello everyone, i was wondering if it is possible that ipv6 dropping more packets than ipv4. i run a test using D-ITG, to test data and voice, but on IPv6 lost more packets than ipv4, special when i sent voice and data together, i was wodering why could that be?, another question, in order to have a dual stack router, i would put ipv4 and ipv6 address on the interfaces, do i need enable something else, because i tried with packets tracer, and i could not ping from an ipv4 host to a ipv6 host, dual stack should allow that right? thank you in advance
thank you in advance

Getaddrinfo function returns IPv4-mapped IPv6 addresses in canonical name

When I use the getaddrinfo function with flag AI_CANONNAME, then in ai_canonname IPv4-mapped IPv6 addresses is returned even for IPV6 disabled machine.
So my question is that from where this canonical name is returned, I didn't found in /etc/nodename /etc/hosts or in /etc/inet/hosts or in /etc/interfacefile files.

It's only showing "unknown" for the IPv6 address.
Go into your IPv6 properties, and set the IP and DNS address settings to be obtained automatically.
Then in Manage network adapters windows, change the view options to show Menu, then click on Advanced, Advanced, and make sure IPv4 is on top instead of IPv6.

How to download nwds deployed local deployed appluication from server,

Dear all,
how to download nwds local deployed application from server please specify the path(if is not a par application and it ia not a dc component)it is a simple webdynpro application i lot my backup in development and quality and the application now exists in PRODUCTION. please help me in resolving this issue.
Regards.

Hi Kishore,
You can't download the full nwds project source. You can get the Java source code only.Select the app.jar file from your project path and it will give all java program code.First You should copy the .jar from (/usr/sap/<SID>/JC<xx>/j2ee/cluster/server<x>/apps/local/ProjectName(x)/webdynpro/public/lib/app.jar)
Some free Decompiler tool are available in online to extract the app.jar source (Tool Name DJ Java Decompiler or unzip the app.jar).
Thanks in advance.

WRT54G v6 not working with new Motorola SB6141 on Comcast (IPv4 and IPv6)

My WRT54G v6 not working with a new Motorola SB6141 Cable Modem on Comcast (IPv4 and IPv6).
Yesterday, I had my old DOCSIS 1.1 cable modem and the WRT54G had been working just fine for the past 8 years.
Last night, I swap in the DOCSIS 3.0 SB6141 cable modem, and now the WRT54G keeps losing the internet connection. When I go into the status page for the WRT54G, I often do not see DNS servers and sometimes do not even see an IP address.
If I connect a PC directly to the SB6141 cable modem, I have no problems whatsoever. But whenever I connect through the WRT54G and power cycle both devices, then I have internet connectivity for about an hour before it drops out. I have noticed my gateway IP address and DNS servers change at that time as well. I can also force the Linksys to lose connectivity by doing a DHCP release/renew on the Linksys status page.
Is this behavior because of the dual stack (IPv4 and IPv6) coming through the cable modem from Comcast now? Is there any way I can keep using my WRT54G v6 now that I have the SB6141 cable modem?

You just have to install it correctly.

Dynamic DNS for ipv4 AND ipv6?

tl;dr: do you know any dynamic dns service and updater daemon that supports both ipv4 and ipv6?
Hi,
ever since my provider supplied me with a proper dual stack account (real ipv4, real ipv6) for internet access I got some kind of little problem regarding the services I host at home. So this is mainly about email. I have a server sitting behind my router that has an open submission and IMAPS port. For ipv4 I've been using the NAT and dyndns features of my router (fritzbox) without any problem. For ipv6 there is no NAT (at least as far as my router is concerned). What I can do though is to open the firewall for incoming ports dynamically based on the interface identifier. So if someone wants to connect to an ipv6 address that would map to my server the router knows to not block the traffic. For this to work though I need update a dynamic DNS record with the public ipv6 address that my server gets to use (something out of the prefix my provider assignes me). This server is an arch linux box. I tried to use inadyn-mt with some systemd unit file I found through google but this does not seem to work right. When I'm in ipv4-only networks (on a mobile connection for example) I often can't resolve the right ip address of my server through dyndns. The thing is that my server doesn't know about a changed ipv4 address because this is handled by the router. It does only know about when his own ipv6 address changes/expires. Based on when this happens inadyn-mt might fire an update to dyndns and with that also pick up the new ipv4 address, but this is not guaranteed.
Any suggenstions, tool and/or service proposals? Is there a way dns-wise to add a CNAME alias just for A records and not for AAAA?

I currently use cloudflare as the DNS servers for my domain as it's free and allows to update certain records with their API. I only use it for IPv4, but since they support AAAA records, I assume it will work for IPv6 just as well. It should be quite simple for you to update the script to get the ip of a given interface instead of fetching it from the net.
