Load Balancing / Clustering Quick Start
After I have gone through the documentation of Administering the server and
Clustering, I still do not know where should I start with and what settings
I need to add. Is there any detailed document concerning setting up a
cluster with Apache plug-in and two WL6.0 servers?
Can anyone please help?
Thanks a lot.

Setting up Load Balancing / Clustering in BIP installation
Hi,
We're upgrading Siebel 7.8 to 8.1.1.5. As part of this process, we'll be replacing the two clustered Actuate Servers with two BI Publisher installations.
We need BIP to behave like for like compared to Actuate (clustered / load balanced) but I cannot any detailed instructions on implementing Load Balancing / Clustering of BIP anywhere.
We use a Loadbalancer.org appliance to balance the Siebel URL - my plan is to use this to support load balancing of the Web Services across the two BIP instances. However, I also need the two BIP installations to share the same repository.
I've come across an Oracle White Paper (http://www.oracle.com/technetwork/middleware/bi-publisher/bip-cluster-deployment-366859.pdf) that states:
The repository is shared among different servers in the cluster
However, looking at the installation guide for Oracle BIP 10.1.x.x.x, there are no details on how to achieve this.
Anyone know where to find documentation explaining, in detail, how to load balance multiple BIP servers to achieve the same level of high availability as we had with Actuate?
Thanks in advance!

Oracle Weblogic Load Balancing/Clustering
Can anyone tell me what the recommendation from Oracle is on how to best set up load balancing?
We currently use the configuration.properties file to identify the 2 servers we load balance. We will be implementing additional servers in the near future and we were wondering if this is the best way to load balance 4 or more weblogic servers or if there is some other way.
We set up one cluster address to utilize these servers and use a separate hardware load balancer device.
HRDEV\webserv\hrdev\applications\peoplesoft\PORTAL.war\WEB-INF\psftdocs\hrdev\configuration.properties
# To enable jolt failover and load balancing, provide a list of application server
# domains in the format of; psserver=AppSrvr:JSLport,...
# For example: psserver=SERVER1:9000,SERVER2:9010,SERVER3:9020As this is peoplesoft specific configuration

Load balancing /Clustring Xservers
I am totally new to load balancing/clustering in X servers. This is my scenario, we need all the designers to start work from the server not on their systems. Only for rendering they would copy the file and throw back them to server. For this kind of purpose what is the best solution I should go for? I hope a load balancing with 2 servers would serve the purpose. Can some one suggest me a cost effective solution?
Hi,
1. Refer to the following links.
http://download.oracle.com/docs/cd/E12825_01/epm.111/epm_high_avail/frameset.htm?ch01s04.html
2. For essbase, oracle provider services enables Load Balancing and Failover functionality.
3. Read about Oracle provider services too.

Anyone and everyone,
When configuring load balancing with Weblogic clusters, does load
balancing take effect for all services or just EJB and RMI? Or another
way of saying the same thing, can I setup weighted load balancing for
the JSP engines across 2 weblogic servers.
Thanks in advance,
MikeThe load-balancing documentation you read describing the different algorithms only applies to RMI stubs (e.g., EJB clients). Please see http://www.weblogic.com/docs51/cluster/concepts.html#1026091 for a description of how load-balancing/clustering works with servlets/JSPs.
The short answer is that in using servlet clustering, most people want/need/use in-memory replication for HttpSession objects. In WLS 5.1 (and before), in-memory replication requires one or more proxy servers be set-up in front of the cluster. Typically, most people use something like BigIP to load-balance
across the proxy servers and let the weblogic plug-in for the proxy server handle the routing to the cluster. The plug-in uses round-robin until an HttpSession is established for a user, then it always tries to route to the server where the user's session is located.
Hope this helps,
Robert

All,
I have a quesiton here regarding load balancing with DNS round robin. As of Chapter Adminstration of Clustering Weblogic server, Weblogic can be configured to balance by weight. How about Weblogic handle weight based balancing after DNS round robin ip response? or just can choose one way instead of both?
What's the big difference between choosing BigIP and software balancing (WL)?

I don't think you can configure this load balancing in weblogic in current

weighted load-balancing there. Otherwise, weblogic proxy will use DNS round

My 2 cents.

ASA Vpn load balancing and failover
Hello all.
We have two asa5520 configured as primary and standby unit in failover configuration, and all is working properly.
Is it possible, with this configuration (failover), to configure vpn load balancing/clustering?
Thanks
DanieleHi Wajih,
I am testing this right now. In my case, I want A and B are failover pairs with A as the primary, (A+B) together as one member in cluster with other ASAs C and D. Here is what I found out:
1, After the active/standby working, configure the load banlancing in the master, the cluster IP worked.
2, after "no fail ac" in A, cluster IP stopped working. Seems the vpn load banlance configuration wasn't copied over to the standby B.
3, In the active (now it's the secondary B), manually configure vpn load banlancing, then the cluster IP worked.
4, "no fail ac" in the B and make the the primary A active, the cluster IP still worked.
5, after "no fail ac" in A, cluster IP stopped working. show vpn load and found out the load banlance was disabled.
6, "no fail ac" in the B and make the the primary A active, the cluster IP then worked.
Based on above, the secondary B's VPN load banlance will be disabled when B becomes active in failover role. If that's true, these two features can't work together. Or maybe there is some configuration I'm missing -- maybe having C or D as the cluster master will help. The ASAs are 5510 with 8.4(2)
Thanks,

Load balancer + Fed auth cookies + Sharepoint
I have a login page which creates a fed auth cookie and establishes session in sharepoint
Now, Since the time site moved to load balancer environment, it started behaving differently
The fed auth cookie is being created. But still I am not logged in!! Which means I am again being redirected to login page for authentication
After another 2-3 attempts, things start working again. Can anyone help as to what is impacting cookies in load balancer? are they being rejected ?Does the ext directory have the php_oci8.dll? In the original steps the PHP dir is renamed. In the given php.in the extension_dir looks like it has been updated correctly. Since PHP distributes php_oci8.dll by default I reckon there would be a very good chance that the problem was somewhere else. Since this is an old thread I don't think we'll get much value from speculation.

Load balancing with multiple clusters (HTTPProxyServlet)
Hello!
I'm newbie in Weblogic. I would like to have clustering and load balancing in
development environment. I've created 2 clusters, with one managed server each.
I've created a web application for deploying the http proxy servlet and put it
under another managed server without clustering. Below is my configuration:
managed server without cluster (as proxy) - Port 8002
admin server - Port 8001
cluster_1 - multicast address 237.0.0.11, multicast port 8004, cluster address
- t3://localhost:8006, t3://localhost:8007
cluster_2 - multicast address 237.0.0.10, multicast port 8014, cluster address
- t3://localhost:8006, t3://localhost:8007
managed_cluster1 - under cluster_1, port 8006
managed_cluster2 - under cluster_2, port 8007
in the web.xml of the proxy, i put the following parameters:
<param-name>WebLogicCluster</param-name>
<param-value>localhost:8006|localhost:8007</param-value>
However, when i send the requests to http://localhost:8002/sms, the requests always
go to the same server, for eg: managed_cluster2?
If i configure using single cluster, the load balancing will be in proper. What's
the cause fo the problem? and any solution?
Thanx in advance.
Regards,
joey
You have 2 options here Jordi, either you can use BGP loadbalancing, this requires multipath as BGP by default would only install one route from the BGP table to the RIB hence FIB.
But this may result in excessive IRL (inter rack link) usage in the cluster when traffic coming in on rack0 wants to take the bGP path out on rack1
You could also use ABF (access-list based forwarding) to forcelly push traffic received on rack0 out on the link on rack0 and use an ipsla tracker to fallback to rack1 in case the uplink is gone.
Alternatively to extend this by IGP signaling to redirect traffic preferably to rack1 to start with to minimize the IRL usage.
And then you also have the ability to use RPL in the uplink path to make one link more preferred on teh internet then the other in case you want to control a bit which link is preferably used on rack0 or rack1

Hardware clustering/load balancing/failover with Tomcat
Hello forum!
I recently bought a Cisco 1801, and it sure is capable! Anyhow, I've got a hobby website that is getting a fair bit of traffic - approaching too much for one node to handle and it's time to start thinking about distributing the load.
I'd like to do a little clustering of server nodes running Apache Geronimo, which is J2EE running atop Apache Tomcat. For the sake of keeping things generic, let's just call it Tomcat because it configures the same way.
I do not run Apache HTTP Server as a proxy, I only run Tomcat directly connected to the internet. I do this for performance reasons.
Anyhow, I'm wondering if any of you evil geniuses could suggest a way that I could cluster Tomcat nodes directly using the router to serve as a hardware load balancer and have the whole sticky session thing with failover, etc... All of the documents I find on the subject discuss clustering by way of Apache HTTP with Mod_JK.
I have already asked this question on the hardware side, and got great information about the capable load balancing features my router sports (but limited compared to Cisco CSS products.)
Now I'm wondering if anyone has experience taking an open source application server like Geronimo or Tomcat or JBoss and clustering it using hardware load balancing. What kinds of Tomcat configurations, if any, do I need to add for things like sticky sessions and failover? Or, is all that automatic?
Thanks so much for reading and for any replies. If there is a better forum for my question, please direct me there.
Cheers,
Dave Woldrich
http://CardMeeting.comThis occurs rarely when the Tomcat process is not able to connect to the database. The database connection problem is an internal cause which manifests externally as missing fields in reports.
Workaround: Restart the Apache process and the Tomcat process. From the CLI on your CiscoWorks Server, enter the following commands in the specified sequence:
1. pdterm Apache
2. pdterm Tomcat
3. pdexec Tomcat
4. pdexec Apache -
Clustering problems and load balancing question
I am using Weblogic 6.1. My Windows NT environment consists of 10 web client-simulator
machines, 2 App. Server machines and one database server machine. I have defined
one cluster on each app. server. Each cluster is running 3 Weblogic instances, or
so it should be when I fix my problems!
My questions/problems are the following:
1. Can I use a software dispatcher to perform workload balancing between the 2 weblogic
clusters? That is, the client-simulator machines send the requests to the software
dispatcher which performs workload balancing between the 2 Weblogic clusters. The
clusters perform round-robin amongst all instances. Note that the documentation only
talks about Hardware Balancing.
2. I am having problems with my multicast IP addresses. For instance, on one App.
Server machine, I am using the multicast IP address: 239.0.0.1 for MyCluster. When
I start the Admin Server, I get a JDBC error: "... multicast socket error: Request
Time Out". I have used the utils.MulticastTest utility which shows the packets not
being received:
I (S1) sent message num 1
I (S1) sent message num 2
I (S1) sent message num 3
I (S1) sent message num 4
What am I doing wrong?
3. Re. the cluster configuration:
NOTE: I have executed my workload using 2 independent App. Server machines with a
software dispatcher - no clustering. Each App. Server used a jdbc connection pool
of 84 database connections. The db connections happened to become my bottleneck.
When I tried to increase the number of connections in the jdbc pool, throughput decreased
dramatically. Thus, I decided to add a cluster of Weblogic instances to each one
of my 8 x 900Mhz machines in order to scale up. Unfortunatly, adding clusters have
not been that simple a task - probably because I am totally new to the Web Application
Server world!
Here is what I've got so far:
I have obtained 3 static IP addresses for the 3 instances of Weblogic instances that
I wish to run within the cluster. All servers in the cluster use port number 80.
There is a corresponding DNS entry for each IP address. My base assumption is that
one of these instances will double up as the Administration Server... Is it true,
or do I need to define a separate Admin server if I wish to run 3 Weblogic instances
(each with a connection pool of 84 database connections for a total of 252 database
connections)?
Do I need to re-deploy my applications for the cluster? And if so, would this explain
why I am having problem starting my Admin Server?
I think this is it for now. Any help will be greatly appreciated!
Thanks in advance,
Guylaine.

We also support software load balancers (for e.g. resonate)
The software dispatcher should be intelligent enough to decode the
cookie and route the request to the appropriate servers. This is
necessary to maintain sticky load balancing.

You should run the above utility from multiple windows and see if each
of them being recognized or not.
i.e. java utils.MulticastTest -N S1 -A 239.0.0.1
java utils.MulticastTest -N S1 -A 239.0.0.1

You have to stress test your application several times and set
maxCapacity of the conn pool accordingly.

BEA recommends to use Admin server for administrative tasks only
like configuring new deployments, jdbc conn pools, adding users etc..
It's not a good idea to have admin server part of cluster.

You have to target all your apps to the Cluster.

Load-balancing issues with iPlanet and multiple clusters
We're in performance test of a large-scale clustered deployment based on WLS 5.1sp10.
Due to scalability/functionality issues, some of which we've seen firsthand and
some of which we've been informed of by associates as well as BEA representatives,
we've chosen to implement multiple clusters with a maximum of three nodes each.
These clusters will be fronted by a web server tier consisting of iPlanet servers
using the proxy plugin.
Due to hardware constraints (both in test and in production), however, we've configured
the iPlanet servers to route across the multiple clusters. In our test environment,
for instance, we've got a single iPlanet server routing across two 3-node clusters,
and the configuration in obj.conf is as follows:
<Object name="application" ppath="*/application">
Service fn="wl-proxy" \
WebLogicCluster="clusterA_1:9990,clusterB_1:9991,clusterA_2:9990,clusterB_2:9991,clusterA_3:9990,
clusterB_3:9991" \
CookieName="ApplicationSession"
</Object>
Our issue is that the load-balancing doesn't appear to work across the clusters.
We're seeing one cluster get about 90% of the load, while the other receives
only 10%.
So, the question (finally!) is: Is this configuration correct (i.e., will it
work according to the logic of the proxy plugin), and is it appropriate for this
situation? Are there other alternative approaches that anyone can recommend?
Thanks in advance,
cramerI use weblogic6.1 with sp2+windows 2000.I develop a web application and deploy
it to cluster.Through HttpClusterServlets proxy of weblogic I found that a server
in cluster almost get 95% of requests but another only get 5% of requests.Why???
I don't set any special parameter.And the weight of the two clustered server is
equal.I use round-robin arithmetic.
Thanks!

Failover clustering Hyper-V + load balancing
I have successfully setup a number of Hyper-V (5) on Server 2008 R2 fail-over cluster environment with two nodes connected to a SAN using MS iSCSI Target 3.3 with cluster shared volume and all is working well.
Now each Hyper-v is run by node-A or node-B. is there a way to have both nodes process all Hyper-Vs at once?
MikeYes you are right I was not using the proper term. I have Hyper-V installed on both nodes and added the Hyper-V service in the Fail-over Clustering service. I can run the VMs on either nodes and distribute the 5 VMs but instead of selecting which node to
run each VM I would like to run all 5 VMs in one environment where both servers (nodes) can manage the processes of all 5 VMs. In other words each server have 64GB RAM and 16 core CPUs, I would like to have my 5 VMs processed by 128GBRAM and 32 core CPU. My
understanding is I am looking at Load balancing, I have seen how to do this with a web application but couldn't find anything on Load Balancing VMs.
You need to configure CSV on top of shared LUN, put your VM images there and run VMs on every host having access to LUN / CSV. See:
http://technet.microsoft.com/en-us/library/dd630633(v=ws.10).aspx
http://technet.microsoft.com/en-us/library/gg610692.aspx
Load balancing is another thing, you can use Live Migration to move VMs from one host to another (no downtime). See:

You can configure HA so one VM would re-boot on another node if primary host is down (minimal downtime). See:

You can configure guest VM cluster so VM would transparently failover to another host if primary one is down (no downtime). See:

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.
