Iplanet-Weblogic in clustering

          My current environment is like this
          1)i have installed Iplanet on Win2000
          2)i have already setup a cluster between two machines one running on solaris/sparc
          and another on HPUnix
          3)Now i want to use Iplanet as webserver using proxy plugin
          Can anybody tell me with this setup can Iplanet running on win2000 can communicate
          with weblogic cluster running on solaris,HPunix machines
          If ok then what is the proxyplugin should i use and minmal configuration steps
          that is to be done
          Regards

 Ranga Rao,
 See the following URL:
 http://e-docs.bea.com/wls/docs61/adminguide/nsapi.html
 This assumes that you're using WebLogic 6.1. Search BEA's "e-docs"
 site if you're running another version.

 Selva Rajagopal,
 I usually try to avoid this (since that's what USENET is meant for),
 but since this thread is fairly old, I'll make an exception this time
 around. Let's hope it (e-mail message) doesn't bounce!

The iPlanet-WebLogic Server 5.1 on Solaris

Does the iPlanet-WebLogic Server plug-in is supported on Solaris platform?.


Hi Matt,
 How do you like it? Is it very stable? I had heard complaints on the
 earlier iPlanet releases (mainly on NT), but I assumed that they were
 probably working better on Solaris. What does performance look like? Did
 you use Netscape server before, and if so, are there any particular
 differences?
 Thanks,

Weblogic & webcache clustering

Hi Guru,
We have 2 node 11gR2 RAC, 2 application server & load balancing H/W (Brocade).
Each node of appserver installed weblogic 10.3.5 & webcache 11.1.1.5.
I'm planning to install weblogic domain clustering on both appserver (appserver 1 : admin server, soa_server ; appserver 2: soa_server).
so my question are:
1. is it possible, config web cache on both appserver connect to individual soa_server, load balancing through H/W; or we just need install webcache on appserver1 and let webcache do balancing on soa_server at appserver1 & appserver2.
2. which is best option, do load balancing with H/W, webcache or proxy server.
3. which is best option for type of datasource if we want to connect to RAC DB, gridlink datasource or muti-datasource ?
4. is it possible to 1 machine/server have more than 1 node . ie. appserver 1 : admin server, soa_server1 , soa_server2, ...
Need your advices, and sharing your experiences
Thx in advance.

1 and 2) http://docs.oracle.com/cd/E21764_01/core.1111/e12036/overview.htm#CHDJDIEH (shows a reference topology)
3) grid link (http://docs.oracle.com/cd/E17904_01/web.1111/e13737/gridlink_datasources.htm)
4) Yes as long as you have enough resources (CPU and memory) on that machine to run multiple servers

NPE using weblogic.httpd.clustering.enable

I'm having some difficulty trying to configure a cluster. If I set the
 property "weblogic.httpd.clustering.enable" to true I will get the attached

 But I do need to use clustering and in order to do that
 I gotta have the weblogic.httpd.clustering.enable set to true among
 all other cluster related properties. What would be the point of using session persistence without
 actually running your servers in a cluster ?
 Right ??

ORACLE WEBLogic 12C Clustering of Admin Server ?

Hi ,
I have setup WebLogic Server 12c on solaris 10 u11, as cluster.
For cluster of managed servers, it works fine.
My Question is, can we run Admin Server from two nodes of cluster?
example: Node 1, created Admin Server, Cluster (F-End1/F-End2) Managed Servers
F-End1 on node1, and F-End2 on node2.
Now for some reason, Node1 has some hardware problem, can i run Admin Server from Node2 ?
I have followed the setup from this website<>
http://www.oracle-base.com/articles/11g/weblogic-11g-clustered-domains.php
Followed Same, Pack/Unpack, Enroll.
Now from Node 1, i can run, Node Manager, ./startweblogic.sh and it takes me to the Admin Server.
from there i can manage every thing.
Question is, can i run Admin Server form Node2? if yes, how?

Node1: 10.0.1.179 Admin Server :7001 F-End-1 7003 B-End1 7020
Node2: 10.0.1.177 F-End-2 7003 B-End2 7020
when i try to run the Admin Server from the Node2, i get error (By 1st running the Node Manager)

Weblogic JMS clustering

Hi All,
I need help understanding weblogic JMS clustering. I read few documents regarding this but not very clear about it.
Hope to get help/suggestion here.
I have following setup
box1 - adminserver, osbserver1
box2- osbserver2
osbserver1 and osbserver2 are clustered together
I have a JMS server created each one for each managed server (OSB server) in the cluster. These JMS servers are non-persistent. persistent store is "None".
I have one JMS module created with connection factory, distributed Qs and are associated with a subdeployment that is targeting to the cluster
I have all the servers(admin server and both OSB servers) are in running state
To monitor JMS server I go to services->JMS Servers
I see jmsserver1 which is targeted to osbserver1 has "Health" is marked as "OK"
jmserver2 which is targeted to osbserver2 has no "health" check
If I go to environment->servers , I see all the 3 servers are marked as "RUNNING" with "Health" OK
As a note I created managed server in the second box before creating the JMS server and resources.
And I do not have any nodemanager setup at this point.
How would I know the JMSserver in both servers are active and have no issues ?
Do I need to do anything to start JMSServer in OSBServer2 ?

Should the JMS Server/JMS modules already be created so that the remote managed server will get configuration of these setup?No. This is not how resorces are created. Pack/unpack is used for creating the domains, ONCE. Later on you may very well use Weblogic admin console to create the resources and target/untarget those.
As a note I do not have node managed setup yet. It is recommended that you use node manager in environments where servers may be installed on different machines -
http://download.oracle.com/docs/cd/E14571_01/web.1111/e13740/toc.htm
To me, it seems a network/cluster communication issue. If you have Oracle Support, better raise a SR with them to find out the exact issue as they would be in better position to understand your architecture and analyzing logs. You may also raise a thread in Oracle Weblogic forum to get a suggestion from a Weblogic expert -

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,
cramer

I 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!

WebLogic Server clusters not high available!!

 I'm working with WebLogic Server 6.0.
 I try to connect to cluster using explicit IP addresses.
 For this case,first ,I cluster server A,B and C ,then client try to look up home
 interface at server A.
 After server A return home reference ,client creates EJB object and calls method
 using that reference .
 If server A fail, it still working with others server ,B and C.
 But if new client try to find home reference at server A ,he can't.
 This situation means that WebLogic Server cluster is not high availability or
 I did something wrong with configuration?
 And if I missed something ,how can I fix it?
 Thanks for your attention.


Hi King,
 If you look up at a non-existent IP/port, then it will not respond. That is
 expected behavior.
 You should not be using an explicit IP like that. At least use DNS round
 robin.

IPlanet - WebLogic bridge, performance

We are using iPlanet as a web server and weblogic as an application server. So, there is NSAPI plug-in,redirecting some requests coming from iPlanet to WebLogic. JSPs pages and servlets are served very fast via this plug-in, whereas static html pages and images are served very slow. Response time (in case of html pages and images) is very long. The weblogic.log file does not give us any errors, whereas /https-.../logs/errors file gives the following:
"flex log buffer overflow" - greater than 4096 characters
What can we do to decrease response time?
Actually we walked through parameters that can be passed into NSAPI plug-in, and we could not find anything in this plug-in related to buffer size.
Attached file is a copy of our obj.conf file
[obj.conf]

We were using the same configuration, and we got the same problems
And we got the solution :
you have to use the libproxy.so from the WL 51 SP8 , using this heavy
bugfixed library
the problems didn't occur.

Now, when i change around the client end to talk directly to the
weblogic server, everything works fine, and the tunneling bottleneck
in performance is not even noticible.
So I have come to the conclusion that iPlanet is causing these
problems. I've tried to setup the obj.conf within iPlanet using the
NSAPI-Plugin to forward tunnelling requests, but it seems to make no
difference. Here is a snip of the obj.conf file from iplanet:
<Object name="tunnel" ppath="*/HTTPClnt*">
Service fn=wl_proxy WebLogicHost=192.168.1.4 WebLogicPort=7056
</Object>
Anyone have any experience with this issue?
Thanks,
Travis

Hi,
There is patch for the webserver(Apache Plugin),thats needs to be downloaded from Metalink,dont use the default plugin that comes with the weblogic 10.3 installtion.

InitialContext for iPlanet/WebLogic configuration

I am using iPlanet 4.1 as my webserver along with WebLogic 6.1. I was
under the impression that you can use the default contructor for
creating an InitialContext which is required to locate the EJB's if you
are an internal client, such as a servlet.
refer to: http://e-docs.bea.com/wls/docs61/ejb/EJB_design.html#1011066
However I get the following error when I create the InitialContext using
the default constructor:
javax.naming.NoInitialContextException: Need to specify class name in
environment or system property, or as an applet parameter, or in an
application resource file: java.naming.factory.initial
If I create the Initial context as follows, everything is fine:
Properties h = new Properties();
h.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
h.put(Context.PROVIDER_URL, "t3://localhost:7001");
InitialContext ic = new InitialContext(h);
Is iPlanet not considered a local client? If so, is there a way to to
configure it within the Web Container as a local client so the default
InitialContext constructor can be used?
Thanks in advance.

More specifically which do I copy over?

Weblogic portal clustering

Hi,
Help Please!
Now we need migrate an application to clustering environment. But there are some confusing scenario.
What we have done are:
1. make all objects in session serializable. For thoese unserializable, declare them as transient and take other workaround to assign value to them when accessed.
2. put up a clustering environment with two managed servers. Here we use IIS as frontend, and weblogic IIS plugin as cluster proxy. In proxy.ini file, we add WeblogicCluster paramter to specify managed server list.
3. add persistantStoreType/replicated session attribute to weblogic.xml
Then we code a simple application to test session replication. The application includes one pageflow. The pageflow has one class level variable and action form.
Now what confused us is the behavior of app upon clustering is not consistant. At the beginning, the session duplication seems works. So after re-setting the pageflow class level variable in a action, the pageflow instance seems duplicated to another managed server. So I stoped current one, and access another action to print out the variable. It works!
But after undeploying/redeploying the application serveral times, the session replication never works again. And each time, when printing out the variable value, it will be the initial value.
Question:
1. Is any other steps/special configuration needed to make clustering works?
2. Portal's pageflow instance is stored in session, is there any special coding criteria to follow to make pageflow instance replicatable?
3. Now in the managed servers and admin server's console, I never see such a debug log:
<Oct 9, 2003 12:38:21 PM PDT> <Debug> <Cluster> <000000>
<Created secondary for 5165892837402719733 on -7957889153726652135S:
192.168.11.112: [9001,9001, -1, -1,9001, -1, -1]: mydomain: MyServer-2>
as mentioned at http://wldj.sys-con.com/read/44435.htm

Weblog 6 Clustering basic question

I am trying to setup Weblogic ver 6.0 Clustering on my Windows NT machine.
 From the weblogic console i created a Cluster, which has the IP address of
 my machine, and given it some name MyCluster.
 I have not given any Multicast IP address to it.
 On the left hand pane : For my servers under Servers/exampleServer
 On the right hand pane :
 I go to Configuration/Cluster window and choose MyCluster for the cluster
 field for my Server exampleServer.
 And click Apply.
 This results in error messages in my Weblogic command line window with lots
 of NullPointerExceptions etc...
 Have i missed any step here ?
 Can any one please give me a step by step guide to creating a Cluster, and
 then adding server (instances ?) to it.
 Do i need more than one IP address (i guess...) ?


 A cluster needs at least TWO IPs (2 IPs in 1 PC or 2 PCs).
 Your IP for cluster should be like 1.1.1.1,1.1.1.2 or cluster.domain
 with two IPs assigned to it.
 That should be why you got NullPoint for the missing 2nd IP.
 You might follow my attached ReadMe.doc and modify my sample config.xml
 for both machines/locations (use same config.xml on the two), modify
 my startExamplesCluster.cmd (for master), startExamplesSlave.cmd
 (for slave) and setExamplesEnv.cmd (for both) to fit yours, and
 try.
 config.xml has all the result you can make in console.
 Cluster feature in WL6 is far from perfect, don't guess the ideal
 possibilities all the time.
 Good luck!

BPM Enterprise for weblogic and clusters

good morning every body
what is the best practice for High Avalibilty Clustered environement for BPM enterprise for weblogic ?
i know that clustering is done on the Weblogic server side but is there is any constraints regarding to ALBPM clustering
if some one would direct me to a diagram of the clustring best practice it would be appreciated!

Hi,
Event I am facing the similar problem but its irrregular(but most of the time). I get following as a log while shutting down the server.
