FMS Clustering Questions

Hi all,
I have a single source of input for video that needs to be
published to a large number of viewers via the FMS. I am aware that
Adobe proposes the use of the Edge and Origin servers for this kind
of solutioning, however, I am unable to find much tutorial nor
walkthrough to set up the network. Is anyone able to point me to a
good guide on how to perform the setup on this?
Alternatively, I am thinking that this can also be done if I
can upload my input source to one single FMS instance and replicate
the inputs (perhaps through replication) to the other FMS instance.
Does anyone has any known approach to this, and maybe a even better
approach or solution to the problem.
Thanks a million!

While the Origin/Edge server is set up for scaling, you can
also do it with multiple pro servers. You can structure your FMS
application to fetch streams from other FMS servers, so you can
spread your streaming app across multiple servers fairly easily.
Look into the SSAS docs for the stream class. There are
examples that show how to connect to a remote stream on another FMS
server.
If you're talking about serving many thousands of clients at
a time, you might be better off using a CDN like Akamai or
Vitalstream. Depending on your business model, it might prove to be
more cost effective.

What is load balancer in fms cluster and how to configure it and testing fms clustering

Hey guys,
I am new to fms and clustering the fms server in origin-edge mode.But i am confused actually what is load balancer and how to configure it .
After configuring , how to test and confirm that fms clustering is working.Is there any one can help me, plz....................
thanks in Advance........

Flash Media Server does not come bundled with a load balancer. In theory, one deploys FMS in an edge/origin configuration like this
1 Origin ----> N Edges ------> Customer Traffic
The idea here is that N edges shoulder the load for most customers with a single origin coordinating resources like VOD content or script access. The issue that remains is "how do I spread customers over the N edges" and that's where load balancing comes in. Most customers use a prepackaged load balancing solution - as an Adobe staffer I can't recommend any of them over the other, but you should be able to get some recommendations here along with just googling for it. The short answer contained here though is, you're going to have to find one outside of FMS if that's needed for your setup.

IronPort Clustering questions

Hello all,
I have some questions about clustering in Ironport:
Actually I have one IronPort C150 in "Standalone mode" with an ip adress who takes the mail flow (192.168.1.34)
We received a second Ironport for setup a cluster configuration between them.
My question are :
1) What happen for the mail flow if the first IronPort ( 192.168.1.34) move to a cluster configuration ?
I have to configure a virtual address to be same of the original ip adress mail flow (192.168.1.34) or the cluster takes the original configuration of the first IronPort ?
2) If one Ironport Fail, the second IronPort automatically takes the mail? or i have to reconfigure manually the ip address ?
Thanks for your help.
PS: Sorry for my english

I agree with your thoughts on MX records. The biggest benefit to using a load balancer is with the management. Once you start getting a large number of hosts in an MX record you start running into problems with senders correctly resolving your MX records due to inproper DNS configuration on the internet (UDP vs TCP). Standing up a large number of hosts behind some load balancers is one potential solution. This of course comes with its own set of challenges.
I'm still using MX records, but at some point will need to look at having multiple machines behind each host in my MX records to cut down on the size of the returned record.
I just wish I could get all of my application developers to write their apps to understand MX records. Load balancers have worked well for my outbound environment where most applications are pointing at a host name instead of an MX record.

Fms hardware question

Hello,
i have a question regarding the hardware of a fms server. We have it installed and working properly on:
CentOS 5.3 64bit
Intel(R) Core(TM)2 Duo CPU E4400 @ 2.00GHz
3GB RAM
2xSATA HDD in RAID1
We are going to stream live video, at a rate of 500 K bits/second, to an
audience of up to 5.000 people, at peak times.
The video will be pushed to the FMIS server as flash files, ready to be
streamed in the right format and bit rate, which therefore do not need any
conversion.
In addition we will be offering, video for streaming download on demand, at
a bit rate of 500 K bits/second, with up to 1000 users at the same time at
peak times.
My question is if thats possible with te current hardware?
Thanks!

Check out pages 17-19 of this doc:
http://www.adobe.com/products/flashmediaserver/pdfs/fms3_5_wp_ue.pdf
It will give you some ideas of how your hardware will measure up. The tests were based on servers that each have a bonded pair of 1Gbps nic's, but actual throughput was limited to 1Gbps (NIC saturation affects performance, so if you'll make more bandwidth available at each box, factor that when factoring processor demands).

OAS Clustering question

Hi
I have a question here, if I would like to create file-based repository cluster for 2 nodes(J2EE container and web cache) 10.1.2.0.2, what should I do first?
1. create the cluster and join the 2 nodes then deploy my oc4j application?
2. deploy my oc4j application to both nodes then cluster them up?
My target : load-balancing

You may wish to create the clusters first and then deploy your application.
The following link would help if you are using 10gR2.

Broker clustering question

In our current setup, we have a few brokers clustered together without a master broker. These brokers serve the same client applications and therefore should have the same set of topics/destinations. My question is should I create these topics on each of the broker or should I just create them on one of the brokers and let JMS provider service to replicate these topics on all other brokers when they are clustered? I have created these topics on the broker before I put it to the cluster and I have seen some strange behaviours with the cluster and I'm not sure if it's related. Does anybody know?
Thanks in advance for your feedbacks.

Currently we created all the destinations on the broker before we added it to the cluster. These destinations are the same as the ones that are already created on all of the brokers on the cluster. Will that confuse JMS service provider because it will try to forward the information to all the brokers in the cluster? We saw messages stuck on ACTIVE subscribers. We saw messages got lost. We saw messages went through for a few hours and a subscriber became INACTIVE for no reasons. I'm not sure if these are related, but I have no ideas where to look.
Is there any reason why you cannot use a master broker?We didn't want to use a master broker because our requirements didn't allow us to have a single point failure. With a designated master node, and if that node dies, will the cluster still function? Another reason is because we have a pre-defined set of destinations and connection factories on all of the brokers, we don't think a master node will be neccessary. Is it correct?
Thanks.

FMS install questions

I have installed one FMS on my dedicated server.
And the OS is Linux Red Hat Enterprise 4.
I installed it by the default manual.
It indicates that I have to enter ./installFMS and answer
following question.
The install process didn't show any error messages.
But when I test the FMS server.
I found it is unable to load any applications.
Only the port 1111 returns response, but the port 1935 is out
of response.
And the process in my dedicated server only loads "fmsadmin".
I don't know if there's anything wrong in my setup process.
Could any one help me to figure out these questions?
Thanks for your kindly help...

Hello
I had a simular problem.
change to /opt/macromedia/fms/ and try to start the core
programm by hand. if a libary is missing it should be printed out.
start it with ./fmscore but check with ps auxf if no instance
is running!
On my system (Linux Debian ETCH 4.0) some libs where missing.
1.) libnspr4
I installed them with
apt-get install libnspr4-dev
I dont know red hat, but look out for a file that holds these
libs
2.) libcrypto
I had to link them correctly
cd /usr/lib
ln -s libcrypto.so.0.9.8 libcrypto.so.4
ln -s libcrypto.so.0.9.8 libcrypto.so.6
ln -s libssl.so.0.9.8 libssl.so.4
ln -s libssl.so.0.9.8 libssl.so.6
After that it started and connections are working.

FMS connection question

I am new to FMS, I need to ask a question, does the Flash Server require an open connection for each instance of same video being streamed, or the connection can be shared. If so, how do I config.

FMS does use a TCP socket - i.e. connection for each video streamed to a different viewing customer. They can't share a connection as they're on different computers/locations. If you're asking on one NetConnection can you stream more than one video, then the answer is yes. Just use the NetConnection over again for each NetStream and you're good to go.

CF8 and JRun 4 Clustering question

I have a production CF8 environment that consists of:
3 Windows 2003 IIS 6.0 servers (behind a load balancer)
JRun 4.0 Updater7 with a CF8 instance installed on each
server .
Each JRun server I created a cluster and added the CF8
instance from each server to it.
I connected IIS 6.0 to the local cluster via the JRun
Connector tool.
My question is when a request is sent to IIS web server for a
CF page, would JRun try to process the CF request locally and if it
could not, then send it to another server in the cluster, or would
it simple do a round robin where as 2/3 of the requests that come
into that JRun server would be sent off to other servers?
Thanks.

what i know that is the request goes in round-robin
process

BAM HA (clustering) Question - Where to run the IIS services?

Referring to the BAM HA guide I have a set up similar to what is recommended for a "medium" sized installation:
Cluster 1 with two nodes running ADC, Event Service, Enterprise Link, IIS
Cluster 2 with two nodes running the Report Service, IIS
The question is which cluster should be the target for users and which should be the target for BPEL sensor actions?
Right now I have individual users pointed to cluster 2 and the BPEL processes pointed to cluster 1. I originally did it this way because the ADC is on cluster 1 and I thought that performance might be better from the BPEL web service call (for sensor actions) perspective, since that is where my primary load is coming from. Doing this seems requires IIS running on all nodes, which to me seems incorrect. If I point everything users, report users, and BPEL sensor actions to cluster 2 is that more correct (i.e. better balancing of load) ?
Thanks!

Thanks for the hint with /var/run/daemons
On the other hand this solves my problem only partially, because using the /etc/rc.d/Serv start method I cannot see the proper order in which the services were started and at what point they failed.
I was expecting to have something like http://www.freebsd.org/cgi/man.cgi?quer … ormat=html
In freebsd the dmesg prints the system buffer, not only the kernel buffer.

UDF or FMS Query Question

Hi,
I have a UDF in Item Master which I call it Part Number.
I don't want to do an auto FMS for this UDF in marketing document row when I select an item. However, I want to type in the Part Number (just like how we are able to type in the item code) in my marketing documents row and the details of the item master such as item code and item description will appear. Is this doable?

Hi Joyce......
BP Catalog is a thing where you can map it but it should have to define BP master also. But if you use Barcode Field into the Item Master Data as Part No. then the moment you select item master it will display its barcode Field as its standard field of SAP and there is no need to have FMS.
But you will have the fix part no. for particular Item........
You can work it out.
Regards,
Rahul

XI R2 clustering question

I am adding new hardware to BusinessObjects XI R2 SP3 FP3.4 environment. We are not upgrading versions. When running install, I would like to configure new servers with their own, independent CMS database instead of creating extended installation, or simply using existing CMS database at install time. The benefit would be that I can install the product any time without imapct to users and take relatively smaller outage time to cluster new servers with existing servers. Are there any drawbacks to this method?

Hi Alan,
I wasn't able to find it at a glance, but I do believe that some clustering instructions are in the Admin guide. But here are your basic steps:
- Make sure that your File Repositories are on a network share. This is a biggie...if they're not, your reports will not run correctly from both servers.
- Make sure that your CMS databaes is on a shared database server. The default installation, I believe, is to create a local MySQL repository. That will probably not work (someone feel free to jump in here).
- In the CCM, give your cluster a name...in the properties section. The cluster name starts with @. For instance, the cluster could be @BOE_CompanyName_PROD.
- Go through your BusinessObjects servers and make sure they're all pointed to the cluster name instead of "servername:6400"
Semi-optional step:
- Change the default login on the Infoview and CMC logins to point to the clustered name instead of "servername:6400." If you don't do this, it's pretty likely that only one CMS is going to be utilized.
There are probably a few things that I'm missing, but that's the general idea. Overall, clustering is surprisingly easy. You'll know it's working when you enter in the cluster name in the Infoview login screen (make sure you remember the @ at the login screen) and are able to log in.
Good luck!

CUC 8.x Clustering Questions / Concerns

Hi all,
I am looking into deploying a CUC 8.x cluster with Pub and Sub at two separate locations connecting over a 45MB DS3 link. I have about 1500 subscribers with 48 voice messaging ports on each server. According Cisco specs for CUC 8.x below I am completely within specs. I am wondering if anyone has run into this scenario with CUC 8.x and could share your experience. Per Cisco recommendation, the subscriber sever will be the primary call processor and the Publisher will be handling replication, maintaining the DB, and MWI. I am wondering if there will be any issues with MWI with Pub and Sub connecting over a WAN link even though my WAN link is completely within Cisco specs.
In my existing Unity 4.0.5 with failover environment. I have the primary Unity server and the Exchange server located in the same building and the secondary Unity server located at the remote site. And I know whenever I failover to the secondary Unity server I always have issue with MWI. I understand Cisco has completely changed the architecture with Unity Connection. I hope this won't an issue.
Connection Cluster Requirements When the Servers Are in Separate Buildings or Sites
Revised April16, 2010
•Both servers must meet specifications according to the Cisco Unity Connection 8.x Supported Platforms List at
http://www.cisco.com/en/US/partner/docs/voice_ip_comm/connection/8x/supported_platforms/8xcucspl.html.
•For a cluster with two physical servers, both servers must have the same platform overlay.
•For a cluster with two virtual servers, both servers must have the same virtual platform overlay.
•For a cluster with one physical and one virtual server:
–The platform-overlay numbers of the physical server and the virtual server must match.
–With Platform Overlay 1 servers, you must add 2 GB of RAM to the physical server so the amount of RAM in the physical server matches the 4 GB of vRAM configured for Connection on the virtual server.
•Depending on the number of voice messaging ports on each Connection server, the path of connectivity must have the following guaranteed bandwidth with no steady-state congestion:
–For 50 voice messaging ports on each server—7 Mbps
–For 100 voice messaging ports on each server—14 Mbps
–For 150 voice messaging ports on each server—21 Mbps
–For 200 voice messaging ports on each server—28 Mbps
–For 250 voice messaging ports on each server—35 Mbps
Thanks in advance !!! I appreciate any inputs / suggestions !!

I was out and about earlier so I wanted to elaborate on my response:
I still think you ultimately have to do what works best for your environment. If that means running everything on the Publisher then so be it. BUT, I think there are too many variables to just move to that solution without further investigation both internally and from TAC. Understandably, a single server can handle the load - if it couldn't, there wouldn't be a standalone option for CUC. However, the concept of clustering is not simply about load balancing to provide high availability. That's a big part of it - but the separation of roles is also intended to provide better performance, scalability, as well as the active-active HA fault-tolerance. If you meet the specs for clustering over the WAN, then I think the product should perform as expected. My expectation would be for there to be very little, if any, noticeable lag in performance especially as far as end user operations are concerned. If what you are experiencing is par for the course for clustering over the WAN with CUC, I would say there are a lot of customers that would be disappointed. I know I would. In saying that, it doesn't meant that there is an inherent issue with CUC. It could be perfectly fine. However, given that you are running an 8.0 release - I would push for some further inspection of the health of the system. If everything is up to spec then there could be something on the WAN link that is at fault. These types of things always take a little more time to investigate but as Markus said - it would still be in your best interest to figure out what is going on here. Even if you have the Publisher sitting at your HQ site doing all the work, it still has to replicate data within the cluster which would be traversing the WAN. So, I would want to pursue both sides of the coin. You may still end up running everything from one box but at least you will have tried to rule out as many potential issues as possible.

WAP321 clustering question

I have two WAP321s at one of my offices. They are in a cluster. When an end-user connects, they do not see each WAP, they just see the cluster name unser "available wireless networks." How does the cluster "decide" which WAP a user will connect to, and how (if at all) are handoffs handled between WAPs if a client moves out of range of one of the devices in the cluster. Are these parameters that can be adjusted?
Thanks,

Queues Clustering Question

Hi,
we are evaluating Sun System Message Queue for our j2ee application and after browsing the documentation we still have one single doubt which is actually slowing down our purchase.
The question is pretty simple,having more j2ee application servers running on different machines accessed via hardware load balancer,
is it possible to have different brokers (one per machine) with a shared store on a network drive, or better to have a "balanced" couple of queues (That's to say, have more queues with separated stores sycronized with each others'), and actually see them as a single queue (via hardware load balancer).
Thanks for your precious help
Michele Zaina

A couple of initial clarifications -
While it is the default with the Sun Application Server configuration, its optional whether or not you run a cluster of brokers with a cluster of app servers (you can run one or many)
A single broker will be faster but wont provide failover (specifically service availability) if something goes wrong.
If you want a single broker for all AS instances, you need to set the service up as "REMOTE"
In MQ, unless you set it up differently, all queues are "global". This means that you set up a single "queue" and consumers can produce or consume from any broker in the cluster. This means you dont need to set up the system to see the queue as the same on all brokers. Messages are stored on the broker they are produced to. e.g.
You have a cluster of two brokers (broker1 and broker2), a producer is on broker1 and a conumer is on broker2. The producer sends a message to broker1, it is stored and forward to broker2 where it is delivered to the consumer.
As far as the shared store MQ does not support a true "shared store" at this time (e.g. on database or persistence store used by all clients)
If you assign the brokers different instance names, you can use an NFS drive and place all file based stores under the same directory e.g. (paths vary on platform)
<location>/var/imq/instances/imqbroker1 - first broker filestore
<location>/var/imq/instances/imqbroker2 - second broker filestore
