Load balancing to a WLS 8.1 cluster with BigIP 9.0

We are experiencing a problem load balancing to our 8.1 cluster using f5's 1500 with BigIP 9.02. The cluster is not configured with any failover capability; we are have configured the BigIP with active cookie insertion persistence; all is well untill we take down one of the nodes in the cluster; any session associated with that node via the load balancer is bounced repeatedly between the two remaining nodes; the only solution appears to be to close all browser instances and open a new one. Has anyone experienced this behavior and have some suggestions ?

How to configure Load Balancer in front of Web Logic Cluster

hi all,
I installed 2 weblogic servers in cluster and now i want to deploy Hardware Load balancer in front of them, i want to know do i require any configuration on servers or i just deploy hardware Load balancer in front clustered servers with round robin technique.
Regards,
imran

I think there are two important configuration when you use hardware load balancer in front of WebLogic cluster.
1) Passive Cookie Persistance
You need to configure hardware load balancer so that it can identify Weblogic session cookie for routing request primary server holding HTTP sesstion.
2) External DNS
If there is firewall between hardware load balancer and weblogic cluster and NAT (Network translation ) is used, then you need to configure "External DNS" for each weblogic server in cluster. You need to specify the hostname used by load balancer in "external DNS".
More details about this are available at.

Load balancing In weblogic 6.1 JMS Cluster

          hi
          i have implemented distributed queues in weblogic as suggested in the JMS performance
          guide.but the problem is that of the 3 queues in cluster the messages always end
          up going to the same queue and the remaining 2 remainin queues are empty. i want
          to perfomr load balancing but i think this ios available only in weblogic 7.0.can
          anyone suggest any alternative workaround ??


I wonder if the JNDINameReplicated setting is taking effect.
          Are there any warning or error messages in your logs?
          Can you see statistics for all three JMS servers on the console?
          Does it work if you use the "./a" syntax?

Load balancing across multiple application servers not working with JCo RFC

We have a problem where inbound messages to the Mapping Runtime engine (ABAP -> J2EE) are not load balanced over application servers. However, load balancing does take place across server nodes within one application server.
Our system comprises of the following:
Central Instance (2 X server nodes)
Database Instance
2 X Dialog Instances (with 2 X server nodes each)
The 1st application server that starts is usually the one that is used for inbound messaging.
We have looked at the sap gateway configuration and have tried various options without much luck:
i.e.: local gateways vs. one central gateway, load balancing type by changing parameter gw/reg_lb_level, see: http://help.sap.com/saphelp_nw70/helpdata/EN/bb/9f12f24b9b11d189750000e8322d00/frameset.htm

WLS Proxy in Cluster with Firewall

We are currently setting up a system that has a DMZ with Netscape inside
          the DMZ proxying a WLS cluster that is behind the DMZ. When a cookie
          based session is started a cookie is returned successfully, but it looks
          like the physical address versuses a firewalled(NATed) address is placed
          in the cookie. This in turn causes a failure on accessing the WLS
          server. The firewall rejects future requests due to the use of the
          physical instead of the NATed address.
          If you understand the above and can help I would appreciate it.

Using Microsoft Network Load Balancing for Livecycle ES 2/2.5 with JBoss clustering?

Hi,
Has anyone tried using Microsoft NLB for Livecycle with JBoss clustering and get it working? Able to login to livecycle's admin ui page with the NLB IP
My enviroment:
- 2 jboss application server (different IP address)
- Horizontal clustered
- LC ES2 installed on both servers
For those who setup successfully, hope you can share your experience.
Thank you.

Thanks!
Just a few more questions...hehehe
In the document: Configuring LiveCycle ES2 Application Server Clusters Using JBoss.
Page 35 item 3.4. Have you had to configure the Caching Locators? If yes, where did you put them, in only one machine or in all of the nodes?
On page 29, iten 2.7 (Testing the JBoss Application Server cluster) says that for testing we can run the command specifying the server, in my case is:
run.bat -c lc_sqlserver_cl -b <ipAddress>
But in the Appendix C: Configuring JBoss as a Windows Service, it says: call run.bat -c all -b <ipAddress>
So when should I start JBoss with "lc_sqlserver_cl" or "all" ?

OBPM Enterprise Deployment on WLS - No Cluster, But Load Balanced

All,
Does anyone know of any gotchas when deploying BPM to WLS on 2 separate nodes, sharing the same directory, but not clustered. The system is load balanced based on F5. Basically we are talking a hot server/cold server deployment.
When we deploy projects, they default to the hot server even if the cold server is specified for deployment.
Anyone done this before?
TIA,
IGS

Hi,
Sorry, but I could not understand completely your architecture.
Are you talking about the Workspace (not clustered but load balanced). That's supported.
Or, are you trying to load balance the engine? (a single engine with 2 or more nodes)
If so.... I wouldn't recommend that you to do that.
Let me explain you why.
The engine uses the queue to balance the work among the different nodes. (that's why you have to configure a Distributed Queue and disable the server affinity in the connection factory).
Even more, the engine has some internal mechanism of synchronization among nodes so as to avoid some inter-node locking. If your engine nodes are not in a cluster, that mechanism will be disabled and the overall engine performance will be significantly degraded.
I'm not sure if I have answered your question. If not, please add more details of your configuration.
Hope this helps,
Ariel

Load Balancing and WLS primary server offset

I've got a load balancer in front of my WLS cluster, and I'm trying to
          set up load balancing based on WLS clustering. What I need to know to
          do this is the offset within the cookie that's responsible for
          determining which machine within the cluster to direct to.
          Any idea how I can get this information?
          thanks,

          In Memory session replication doesn't work without our plugins. I will have to
          do little bit of investigation to figure out if other persistence mechanism's
          would work without our plugins if you are interested in them. I have to remind
          you though that other types of persistence mechanism's we support are slower
          compared to in memory session replication.

          Currently none. We are taking steps to make the plugin's and cluster more
          robust, we currently don't have any plans to work with other 3rd party vendors.

          This information is saved in the cookie. But I wouldn't count that, as we
          have plans to change this. I cannot give your more details.

          I don't quite get what you mean here.

BPEL + AQ + Load Balancing + OAS Cluster

Hi all
Is there a way to provide load balancing when reading AQ messages (JMS queue, not topic) to a OAS Cluster?
Explaining:
A BPEL server reads a flat file and send JMS messages using an AQ adapter. In the other side, there is a Java application running on a OAS cluster expecting the JMS messages, reading the queue on the AQ. As there is just one queue and many consumers (6 applications instances running on the cluster), how can I provide JMS load balancing between these 6 applications?
Sorry if this is not the correct forum to post, if you could recommend another forum I would be glad.
Thank you
Marcelo

Hi,
thanks for your answer. could you please be more specific? We have found something in the JMS specification:
JMS Spec 1.1 / Sun:
6.11.1 Durable TopicSubscriber
Only one session at a time can have a TopicSubscriber for a particular durable subscription. See
Section 4.3.2, Client Identifier, for more information.
So only one instance (JVM) can have the JMS-connection open to the Topic. How do we load balance these messages then into the Oracle Application Server?
As a workaround, we we have currently deployed a "singleton EAR" which acts as a messaging bridge. It transfers messages from the topic into an "incoming queue" at AQ database. That queue is configured and visible on all OC4j instances. Is this the right way to load balance messages on a OC4J/OAS cluster?
grüße,
\thomas

Who takes care of load balancing work in weblogic cluster ?

Hi Folks,
How load balancing is handled internally by weblogic cluster ? Does Admin server takes care of cluster load balancing ? According to me Admin has nothing to do with load balancing in cluster . Manage server continue to run even when Admin server is down.
I am not looking for explanation about different load balancing algorithm. I am interested in who executes those algorithms in weblogic cluster and how .
Cheers
B.

Hi,
You need to configure loadbalancer and there are different ways to do this. Please go through the below thread to user Apache Loadbalancer.

Ironport Cluster Load Balancing

Anyone knows if it is possible to configure a load balancing of two C100 in a cluster.
I configured the second machine in the cluster two weeks ago. when I look in the stats, the second machine does nothing. the first machine is on 3% CPU and whe have about 120000 mail per day.
is there any way to configure the cluster that the two machine share their work ? or is the cluster only for fail-safe ?

Hello,
Most mail admins know how to use MX records for load balancing (and redundancy) on their mail servers.
Less people know you can use MX also for your outgoing mail traffic.
Just add a MX record to your local DNS and specify a name for the record. (i.e. outgoingMX.local.domain) put the IP's or hostnames of your internal Ironport card in the data and configure your internal mail system to deliver it’s outgoing mail to smarthost outgoingMX.local.domain
Works for most mail systems. I'm sure it is working for Exchange (5.5. and higher) and Domino (5 and higher)

Question about Cluster/DSync/Load Balance

According to the admin doc of iplanet, primary server is
the "manager" for data sync, is there any impact on
load balance when the iAS run as primary or backup?
will the primary kxs get the request first and do dispatching?
Thanks.
Heng

First of all lets discuss load balancing....
The type of load balancing you are using will determine which process manages the load balancing. If you are using Response time (per server or per component response time) or round robin (regular or weighted) the web connector does the load balancing. If you are using User Defined (iAS based) load balancing then the kxs process becomes involved with load balancing of requests since the "Load Balancing System" is part of the kxs process.
Now for Dsync and how it impacts load balancing.
When a server is a sync primary or a sync backup role it is doing more work. For the sync primary the extra work is making sure the backup has the latest Dsync Data and processing requests from the other servers in the cluster about the Distributed data. All state/session information is updated/created/deleted on the sync primary, when this happens the sync primary immediately updates the sync backup(s) with this new information. As you can guess managing the Dsync information and making the updates to the sync backups causes extra processing on the sync primary, so this will impact the overall performance of the machine (whether it be in server load or response time of processing). All lookup of state/session information is done on the sync primary only so the more lookups/updates you have to more impact on the server.
The sync backup(s) also have the extra work of managing their copy of the Dsync Data which will impact server performance but to a lessor degree of the sync primary.
Ultimately the extra overhead involved does have an impact on loadbalancing due to the extra load on the sync primary and sync backups.
Hope that helps,
Chris Buzzetta

Using StoneBeat WebCluster load balancing with WebLogic

          Hi,
          I have done some testing of WebLogic Server with my company's StoneBeat WebCluster
          distributed load balancing software. This might be one more option to consider
          as a load balancing solution for WLS. It is advanced in the sense that load balancing
          is really dynamic, there are no single-points of failure (distributed architecture)
          and there is a very good, configurable test subsystem that runs on each cluster
          node to check for overload situations, HW/OS failures, ...
          In the initial testing, the WebCluster load balancing works with WebLogic replication,
          although there are some cases that need mroe consideration (please see below).
          I had to get a patch to WLS6SP1 on NT to make WLS' multicast work when there are
          several NICs on the cluster nodes.
          However, there is one case which causes problems:
          - I have 3 cluster nodes
          - P: 2, S: 3 (SessionServlet = 1)
          - 2: offline - P: 3, S: 1 (SessionServlet = 2; WebCluster randomly selected a
          new node to handle the connection)
          - 2: online - P: 2, S: ? (SessionServlet = 3, WebCluster redistributes the load
          when a node goes online)
          - 2: offline
          - P: 3, S: 1 (__SessionServlet = 1__) NB!
          The log messages show that when node 2 comes back online it retrieves the replica
          from the secondary (node 1) and not from the primary (node 3). After a while (5-6
          minutes), node 3 tries to update the replica on node 1. Node 1 considers this
          a stale update request and removes the Primary 16... (node name) and then the
          secondary for 16... (the replicated object). Then there's a message (still on
          node 1) that it is unable to find object 16... Back on node 3 the primary for
          16... is removed.
          From the WLS6 documentation (under the discussion of using replication with external
          HW load balancing solutions) I thought that this case would have been handled:
          - it is stated that after the failure of a node, if the HWLB box sends the next
          request to a node where there is no replica, WLS is able to retrieve the replica
          - to be fair, this is what happens: when node 2 came back online, it retrieved
          the replica from node 1 (the secondary) - I suppose that there is an assumption
          that if a request arrives to a node without a replica, the primary __must have
          failed__
          Is there any way to get around this problem?
          Admittedly, WebCluster has a problem in that the stickyness of connections is
          not perfect: - when a node goes online, a connection that was correctly persisted
          (based on either source-ip or source-network address) may be moved to a new node
          since the load is redistributed. Our load balancing is very dynamic, but doesn't
          maintain a list of who is connected to which node when resistribution takes place

Rick,
You may want to look at the Alteon and F5 configuration we have on edocs.
Take a look at the following URLs for a possible solution

Distributed Queue - Unable To Load Balance Between Each Time A Send Method Is Called

Hi,
          According to the JMS documentation, I should be able to get the
          distributed queue to load balance
          between each time the message producer calls Message.send(). I was not
          able to achieve this, however,
          I noticed the load balancing happens when a JMS client is stopped and
          restarted (meaning totally
          exit the JVM and restart the JVM).
          Here is my configuration:
          WLS 8.1 SP2 on XP
          One cluster with two nodes (running on the same machine w/ different port)
          Each node hosts one JMS server, which hosts one physical queue and using
          JDBC store
          One distributed queue with two physical members from each of the JMS
          server.
          JMS Connection Factory is configured with "Load Balancing Enabled" set to
          yes,
          and "Server Affinity Enabled" to no. This connection factory is target to
          the cluster.
          The queue session for the queue sender is created with transaction setting
          to false.
          Any hints and ideas would greatly appreciated.
          Here is the content of config.xml:

Thanks for the Makiey. I am surprise that BEA hasn't come back with any

Office Web Apps Load Balancing Configuration Issue for SharePoint 2013

I have load balanced servers dedicated for Office Web Apps with name “md1xxxwfe1” and “md1xxxwfe2”
, both this servers are load balanced by CISCO Load balancer. And I have mapped Load Balancer Virutal IP with host name officeapps.jda.corp.local in the DNS records.
Things are working fine if I add new farm by using New-OfficeWebAppsFarm
with server name as internalurl in PowerShell console
as like “ -internalurl http://
md1xxxwfe1 but when I use –internalurl officeapps.jda.corp.local it is not working at all. I’m not getting what to do at this point.
I have gone through following blogs but no luck.

http://sps2013.blogspot.in/2013/09/office-web-apps-with-sharepoint-2013.html
The output of the wfe1 server is attached with this. When I open http:// /hosting/discovery in wfe1 I’m getting following result (attached
screenshot) but it should show hostname rather than server name.
Please help me
Thanks, Ram Ch

Hi Ram ,
For troubleshooting your issue, please take steps as below:
Just about any load balancing solution will work, including a server that runs the Web Server (IIS) role running Application Request Routing (ARR):Install
Application Request Routing
Install the certificate on the load balancer as described under Securing Office Web Apps Server communications by using
HTTPS.
Make sure you have configured the cluster correctly for full internet name:
