IP Multicast requirements in WebLogic 5.1 cluster
Hi,
Does multicast need to be available to servers containing the Weblogic plug-in?
We have a firewall between web servers (iPlanet) and the WebLogic cluster.
Thanks in advance,
Julian
Another way of putting my question:
How does the plug-in become aware of the need to failover (eg. to a replica session)?:
(i) - "A Proactive method" -Plug-ins listen to cluster heartbeats to determine
instance availability, only send requests to available instance (e.g. compare
list of available instances from heartbeat results against primary/secondary instances
specified in cookie).
(ii) - "A reactive method" - Plug-in sends client request to Primary instance
specified in cookie, request is not fulfilled, so intercepts response to client
and re-sends request to secondary instance.
(iii) other ??
Please help.
Thanks again - Julian

Hi,
I am using Weblogic 6. I have created a new Web
Application called Web (I have not used the DefaultWebApp_myserver).
And I have the following settings:
Name : Web
URI : Web
and Path : C:\Web
and placed my JSP files under c:\Web\
I am able to access the first page, but after that I am not able to access the
second page.
I get "Error 404--Not Found" on the browser. Basically the class file is not getting
created under /Web-inf/_tmp_war_myserver_myserver_Web/jsp_servlet/ folder .
I tried a work around for this. I copied all my files under one more folder called
web and placed this under C:\Web
The it works. Now I have 2 copied off all the files, 1 copy under c:\web and another
copy under c:\web\web\.
If I have the files under DefaultWebApp_myserver and have the setting as
Name: DefaultWebApp_myserver
URI: DefaultWebApp_myserver
Path: .\config\mydomain\applications
everything works fine.
Can any one please let me know if there is any configuration which has to be done
so that I do not duplicate the code in 2 directories
Thanks in advance.

Jaas.jar conflict in Weblogic 6.1 cluster
We are using a Custom realm for Weblogic which communicates with Tivoli Policy
director for user authentication and authorization.
For communicating with PolicyDirector, We need to have IBM's jaas.jar as a JDK
extension(in jre/lib/ext directory)along with some more jar files.We never had
problems when running Weblogic in stand alone mode.But when we are trying to run
Weblogic as a cluster, Managed Server is not able to communicate with Admin Server
giving following exception:

When we removed IBM's jaas.jar from jdk/jre/lib/ext to check the clustering.It
works fine.But We need to have jaas.jar for our custom realm.
Thanks.
Jagan.Hi jerry
i already got that problem solved by removing jaas.jar file
from class path.
i don'nt how it is working with out in classpath...?
Jerry <[email protected]> wrote:
Hi Nivas,
I think that the problem you are seeing has something to do with the
placement of jaas.jar in your classpath
On WebLogic server, put jaas.jar in the classpath after weblogic.jar.
I would bet that you have it placed before weblogic.jar right now.
I don't think the exception that you're seeing right now has anything
to do with your weblogic.policy file right now, so I think it is
safe to not worry about it right now.
Hope this helps,

Weblogic - Fusion Middleware Cluster - Clarification - 11g
Hello All,
I've checked the forum and would need just a little clarification regarding weblogic cluster & fusion Middleware + Load Balancing.
My current Setup is:
==============
1 APP Server: Runs Fusion Middleware 11g Forms and Reports + Weblogic + OHS (windows 2008R2)
1 DB Server: Standalone database 11gR2 installation (windows 2008R2)
I've been asked to add a new app server and setup load balancing between the two app servers in order to split the incoming forms & reports requests.
What do I do? Do I install the new app server like the first one and just add it to an existing domain(clustering)? Is there a difference between fusion middleware clustering and weblogic clustering (as in database RAC - the whole idea being failover 24/7 no single point of failure?)
I would appreciate any assistance, and need not great detail, just need to make sense of the whole thing.
I'm already on with the following document: [http://docs.oracle.com/cd/E21764_01/web.1111/e13709/toc.htm]
Thanks in advance
Jan S.Hi Jan
You are almost there. I would like to clarify some points for you.
1. You already have WLS + Forms/Reports and of course Backend RCU Database that has all the meta data for Forms/Reports. This RCU database is on single server Oracle database.
I've been asked to add a new app server and setup load balancing between the two app servers in order to split the incoming forms & reports requests.
2. The first question for above requirement is, do you need the new Server on the same Existing physical box or a different remote physical box. If on the same physical box (which I doubt), then there is NO need to install any new software like WLS, Forms/Reports etc. All you do is create a new Managed Server and add it to your existing Domain. NOW, do you currently have a Clustered Domain. If you, all you do is add this new server to that cluster. If not, then you need to add a New cluster and add your old and this NEW managed server to that Cluster. If your existing domain is only single server and is very recent, I would prefer create a brand new Cluster domain with Different Port numbers (you can change port numbers anytime later also). Then add/create one or two managed servers.
3. If you are give a new physical box for this new managed server, then YES, you do need to install exactly SAME version of Weblogic Server and same version of Forms/Reports server on this new machine. Then create a Cluster Domain with 2 managed servers. One managed server on first box where you will have Admin Server + Managed Server 1. Then run pack command. Go to other machine. Run unpack command to create second Managed Server. Now you got 2 managed servers in a Single Clustered Domain.
4. Now comes the Load Balancing Part. Never ever expose the individual managed server host and port and WebApp urls for any Clustered Domain. Instead install Apache Http Web App Server which I guess is same as Oracle Http Server. Oracle renamed it (there is no need for this, but it may be company policy). Anyhow all you do is, just install Apache Web Server. Copy some .dll (.so on linux) files to this apache installation. Then update httpd.conf file or weblogic.conf file with details of clustered weblogic domain managed servers host, port, url patterns etc.
5. All the External Requests will now go to Apache Web Server like http://apachehost:apacheport/xxxUrl. This Apache will take care of LOAD Balancing, Failover etc and based on input url pattern will redirect requests to back end cluster of weblogic managed servers.
6. The backend RCU database that has Metadata for Forms/Reports NEED NOT be Clustered. If you really have extremely heavy data, then you can have Oracle RAC database. Have multiple DB Nodes in RAC. For each Node, create a DataSource in Weblogic conolse and finally one master Multi Data Soiurce that uses all these single Datasources. But very rarely you really need RAC or clustered database for RCU. So for now, just go with single non-clustered Database that has RCU Schemas.
In conclusion, even though you have Forms/Reports, just follow the standard normal Weblogic Clustered domain Architecture for your requirement. All clustering is at application server level and nothing to do with any Oracles softwares like SOA/BPM, Forms/Report, BI etc etc.
Thanks

Hi,
I configured one Weblogic 7 Admin server with two clustered managed servers.And
I could start
clustering service sucessfully.It was working fine and cluster service was healthy.Then
I ran the weblogic IPMulticast utility (while cluster serivice was running) then
Weblogic
admin server console showed a exception stack trace.After that I cannot restart
any of the servers even after deleting all existing domains and creating brand
new domains using configuration wizard.It is giving me nullpointer exceptions
and configuration exceptions when I run startWeblogic script.
Do I need to reinstall WebLogic.
Please help me to solve this problem.
Gayan Balasooriya.
Multicast test should be only conducted when the servers in the cluster are
down.

Weblogic Portal in Cluster-Mode : Synchronization Instance problem
I've got 2 different servers running Portal with Avitek example
On the first server, I've got The Admin Server and the first Managed Server of my cluster.
On the second server, I've got my second Managed Server of my cluster and the Synchronisation Server.
Question 1 : Should the Synchronization Server be a managed server or not ?
Question 2 : As Admin Server should not respond to any customer requests, can I deploy all applications only on my Managed and Sync servers (except p13nConsole of course)?
[att1.html]Laurent,
ADMIN
DataSync WebApp
| |
| |
Managed 1 Managed 2
Data Sync WebApp DataSync WebApp
[ all three machines share a database ]
So you configure your admin machine to not have any of the EJBs deployed, just an instance of the DataSync WebApp. You configure the DataSync WebApp (through Servlet context parameters) and give it the URLs which the other two managed machines Data Sync WebApps are listening on.
Once you are in production you can disable the DataSync WebApps on the managed machines to ensure no one can send data to them directly.
You can places the sync server on either a managed node or the admin machine. It doesn't matter too much from a technical standpoint which - it depends on your licensing requirements etc.
By default the Master DR on an admin machine will use the RDBMS in read/write mode, while the Master DRs on the managed machines will use read-only mode (so you don't get redundant writes). If you move the sync server onto one of the managed machines you will have to explicilty put it into read/write mode by setting the System properties: data.sync.jdbc.master.dr (read/write RDBC) or (data.sync.jdbc.read.only.master.dr read-only JDBC).
You can check your configuration from the Data Sync management pages:
http://localhost:7051/p13nAppDataSync/index.html (example)

Problems processing a large batch of data within a Weblogic 5.1 cluster
I have about exhausted my sources of information on this, so I ask the
experts:
The project I am involved with is attempting to build a scheduled
process on a 5.1 cluster which will retrieve hundreds to thousands of
database rows from a small group of Oracle tables and then submit them
into a legacy system for processing. The problems we face are:
1. We cannot have duplicate data submitted from startup classes on
different servers in the cluster
2. We need the process to run if even only one machine in the cluster is
available and therefore do not want to tie the process to a single
machine
3. We would prefer to distribute the workload across all servers
currently available in the cluster, but this is not mandatory.
One solution is to retrieve each record as an Entity bean, attempting to
update it to "in process" and rejecting any failures thus utilizing
database locking, but due to the large number of records being processed
this is much too resource intensive as well as time consuming.
We have looked into JMS based solutions, but it appears that JMS under
5.1 is tied to a specific server (failing case 2).
One acceptable approach that we have yet to find a way of implementing
is to have a "singleton" session bean, only one of which exists on the
cluster (though it may exist anywhere on the cluster). I have run
across a number of other applications for just this sort of EJB, but is
it possible to implement?
Sadly, Weblogic 6.0 cannot be part of the solution as our company will
not be adopting it until well after this project's delivery date.
Are we missing something obvious?
Many thanks!
-Steve
You have to have all the servers in the cluster polling for work out of the
database. Use the database as a scheduling / routing mechanism. Use timers
on each server in the cluster to kick off a "find me one thing to do"
process every n minutes or seconds.

Error when running weblogic 10 in cluster
I am testing out weblogic 10 and when I run it with a single managed server and an admin server then everything works fine. When I run it in a cluster with a valid test cluster license, I get the following error. Does anyone know what the cause of this error is and how to fix it? Thanks for the help.

Problem connecting weblogic server to cluster
Hi,
I am very new to WL/JMS/JNDI/EJB etc. I downloaded WL6.0, and tried to make a cluster. I started a server on one machine as Administrative server, and created a cluster. Now, I started another server on a different machine, as a managed server by adding the following parameter at startup
-Dweblogic.admin.host=http://admin-ipaddr:7001....,
I get the following error

I understand that all managed servers are supposed to use the same config file as the Admin server.
Also, I am not clear about the domain parameter.... what should I pass for -Dweblogic.Domain=mydomain (this is what is there in the batch file that comes). Should I change this parameter for Managed servers, which points to Admin domain? If so, how do I do that?
I am struck up on this. I'd greatly appreciate it some body could help me out.
thanks a lot,
Anil.
-Dweblogic.admin.host=admin-ipaddr:7001, you shouldn't specify protocol. Also please use beta newsgroup for 6.0 related questions.

Reg. Weblogic 8.1 cluster licence?
Hi,
I have received Weblogic platform 8.1 CD with the 1 year developer licence.
Can i create a cluster and test my application in this cluster.
Do i need a seperate cluster licence to test my application,
to support load balancing and failover??

rgds,
girishIn general the developer license gives you the ability to configure
and run clusters. One really easy way to tell is to install it and
look @ licence.bea. You'll see(or not see) a cluster component
in there.

Weblogic 9.2 cluster install across 2 linux servers - authentication errors
Hello all,
I am currently trying to install a 9.2 cluster across two Linux machines, but am having a few problems that I was hoping someone here could help with. I?ve been reading the documentation, but feel as though it?s getting me nowhere.
I have two servers, on which I have installed weblogic portal 9.2. On the first I have then used the configuration wizard to great an admin server and cluster members 1, 2 and 3.
A cluster is created and the three cluster members are assigned to it.
Then I configure two unix machines, for the servers 1 and 2.
I assign the admin server and cluster member 1 to the first server. Cluster members 2 and 3 are assigned to the second server.
The connection pools and JMS stores I left as the default values.
The configuration completes and a domain is created on the first server.
I have copied the complete user_projects directory to the second server. I didn?t want to go through the configuration steps on each server that weblogic was to be installed on, so this looked like the easiest way to get the startManagedWeblogic scripts onto the second server. Also I didn?t find anything in the documentation that mentioned how to set up a cluster across multiple machines in any detail, only how to install multiple instances on a single server and run them as a cluster.
I manage to start the admin server ok and can connect through the web based admin console.
The first cluster member also starts up on the first server.
Now I go to the second server again, and when I try to start the cluster members here I get Authentication errors:

What am I doing wrong / forgetting to do.
Any help or suggestions are most helpful
Regards
IVHello ,
I can help you in this regard, (let me see).
Let me start from the beginning.
Assumptions:
M1 is hosting 1-Admin server(AdminServer), 2-Managed Server(ms1,ms2),
M2 is hosting 1 -managed server (ms3)
1. Install WebLogic Server/Portal product on M1 and M2 say /home/user1/bea1 - on M1
/home/user1/bea1 - on M2
2. Create Cluster Domain using ConfigWiz/WLST.
[ here I will talk abt Config Wiz)
- Open config Wiz
- Create domain in Production Mode.(ideally Cluster is not supported in Dev mode )
- Create 1 Admin server, 3 Managed server Host = <M1> and config SSL port
AdminServer ? Host_M1
Ms1 ? Host_M1
Ms2 ? Host_M1
Ms3 ? Host_M2
NOTE: *** Don't use IP addresses - use hostnames. The hostnames need to be specified in the correct format. When specifying a hostname, use the receiving server side's rules for SSL certificate hostname format when specifying the server address. The address that a client uses needs to match up with the server's SSL certificate host identity field ((example: pint21.bea.com on both server/client side, not just pint21 and other pint21.bea.com)
Using the 'keytool' Java utility, verify the content of hostname identity embedded in the demo SSL certificate
$ keytool -list -v -alias demoidentity -keystore DemoIdentity.jks
Owner: CN=pisol18, OU=FOR TESTING ONLY, O=MyOrganization, L=MyTown, ST=MyState, C=US
- Config Data Source (conn pool) to Any DB Type you like, test them and run the DB scripts if applicable (Run DB).
3. Create Managed Server template Using Pack/Unpack tool
3.1 Using <WL_HOME>\common\bin\pack.cmd with ?managed option create managed server template.
3.2 Using <WL_HOME>\common\bin\unpack.cmd on M2 to create the domain on Host2
4. Starting the Admin Server
5. Start the Managed server in many way. As given on edocs.
http://edocs.bea.com/wls/docs92/ConsoleHelp/taskhelp/clusters/StartOrStopAServer.html
I hope this helps you,
Thanks

ORA-01017: invalid username/password; logon denied on Weblogic 9.0 cluster
I am experiencing the following exception in Weblogic 9.0 server cluster environment. The same code works fine in non-cluster environment. The problem happens every now and then and would go away temporarily after recycling the domains. The Oracle database that the backend system connects to is 9.0.2.6. I am using the ocjdbc14.jar jdbc driver that comes with the Weblogic 9.0 on the client side to connect. I really appreciate any help or clue.

at weblogic.work.ExecuteThread.run(ExecuteThread.java:179)Hi, I can tell you that you're not using any WebLogic
JDBC code. You're getting a connection directly from
the Oracle drive, and you can change the vesion of the
drive if you want by changing the ojdbc14.jar in the
weblogic server\lib directory.
However, I believe the problem is an inherent weakness
at the DBMS. The DBMS listener process can sometimes
be temporarily swamped if it gets too many connection
requests at one time, and will fail some of them even if
they are all identical and correct.
This is one of the major reasons you should use WebLogic
connection pools so you always get already-made and
tested connections.
Another huge danger is that you are using DriverManager
calls. These are very bad in multithreaded applications
like WebLogic, because all DriverManager calls (including
some internal ones that all JDBC drivers call all the time,
are class-synchronized! This means that one call to
getConnection() will probably bolock all other running
JDBC in the whole JVM. If you can change the springframework
code to use WebLogic DataSources to pools, you'll be much
better off.

Requirements for a HA VMM Cluster
Here is my situation. I want to setup a HA VMM 2012 R2 Environment as outlined in this article: http://blogs.technet.com/b/scvmm/archive/2014/07/03/setting-up-a-highly-available-vmm-2012-environment.aspx
I have run into a couple of snags and I am having a hard time figuring out what exactly the best way to proceed is. I have an existing VMM Server (VMMA) that was setup before I started at my company (by a Microsoft person during the initial System
Center installation engagement) and nobody knows anything about it. I have figured out that it is already setup to store Keys in Active Directory. However, it is only using a single installation of a SQL Server (not a clustered SQL Server).
I have added a second VMM Server (VMMB) but during the installation I don't get any option to add or configure a cluster name.
Here are my questions:
Is it possible that this single installation of a VMM Server is already setup as a "Cluster"? If so, how can I find the Cluster Name? I have searched DNS for anything I can think it might be and haven't found anything.
Will I only be able to name/create a VMM Cluster if I am using a SQL Cluster to store my VMM DB?
Is it a requirement to have the VMM SQL DB Cluster on a separate Hyper-V Cluster from the VMM Cluster or simply a "best practice"?
Is it possible to create a VMM Cluster after the initial installation of VMM was not configured that way?
MCITP | VCP4 | VCP5Hi,
my respond:-
1. You can check by using Failover Cluster manager console. Besides during VMM installation, when you add 2nd node, it will prompt to add this 2nd server as a node to
the highly available VMM installation.
2. Not really. You can have
a) VMM Cluster with standalone SQL
b) VMM Cluster with SQL cluster
3. It is best to only install Hyper-v roles and do not install other roles. You can create VM to host the SQL
4. Nope. You must select during installation (after setup cluster). The url that you provide has the screenshot that
will ask "Do you want to install management server into cluster".
