Weblogic plugin and cluster concepts

Hi,
I would like to clearly understand how the plugin and cluster work together in achieving load balancing.
For example if Apache proxies the request to each server instance in a cluster(if we use weblogic cluster parameter) on the round robin basis. How does the cluster do the the load balancing and how does it respond to webserver. I have read some documentation in edocs but couldnt find anything that would clearly explain how this works. All it talks about is the configuration of plugin and load balancing techniques in the cluster.Please throw some light on this and help me figure out how this thing works.
Thankyou very much.

Hi Hoze,
In Oracle Enterprise Manager lingo, a plug-in simply enables EM to monitor heterogeneous environments. In some cases this capability is available OOB or after the fact.
The table here
http://www.oracle.com/technology/products/oem/extensions/index.html
makes it clear if a plug-in is available OOB or available for download.
Thanks

Problem with weblogic.deploy and cluster

 I'm having some problems with the weblogic.deploy class when trying to refresh
 a jsp file. Using the following command to redeploy the entire application works
 fine:
 java weblogic.deploy -port 9876 -host apptest01 update
 administrator portal c:\portal-site
 However using the following command to refresh just one jsp
 file:
 java weblogic.deploy -url t3://apptest01:9876 -username system
 -jspRefreshFiles ./index.jsp -jspRefreshComponentName portal
 refresh administrator portal
 produces the following stack trace:

 Hi John,
 How's tricks?
 It looks to me as though the olbcluster JNDI reference isn't being resolved from
 the tree. A similar error results when a Connection Pool cannot be resolved, the
 JNDI context env.jdbc is resolved but the particlar pool isn't. In my experience
 it often turns out to be an error in the correlation between the deployment descriptors,
 settings applied via the console and references made in the code.
 That's my tuppence worth,
 James :-)

Weblogic RMI and Cluster

Hello,
We are deploying services that use legacy code via JNI. For safety, we want to
run these processes in separate JVMs and plan to have the application server(s)
access the code via RMI. To handle the system load we want to option to run multiple
instances (multiple JVMs) of these services.
WebLogic's rmi clustering support seems to be a good fit, but we are confused
on how to deploy the services.
In clustered environment when we run
java weblogic.rmic -clusterable classname
It created classnameRTD.xml file. Presumably this file needs to be put somewhere
to deploy the service? Where does it go? Do we have to do anything else to handle
the replica aware stubs and make them available to our client (in our case EJBs
running in the application server(s)?
Can we run replica aware stubs in a non-clustered application server? This would
allow us to have multiple instances of our service handle the load from a single
application server.
Thanks,
Tushar Shah

Apach 2.2.21 using Weblogic Plugin (10.3.5)

Hi All,
I have configure apache using Weblogic Plugin and it work for http. So moving forward, i am trying to configure a 2 way SSL with weblogic plugin and have configure all the oracle wallet.
I got my plugin from my weblogic server /opt/bea/wlserver_10.3/server/plugin/solaris/sparc/. The version of my weblogic is 10.3.5.
When i do a apachectl -t to check the syntax and i got the following errors:
# /usr/local/apache2/bin/apachectl -t
Syntax error on line 475 of /usr/local/apache2/conf/httpd.conf:
Invalid command 'WLSSLWallet', perhaps misspelled or defined by a module not included in the server configuration
Below is the configuration files on my httpd.conf
<IfModule mod_weblogic.c>

Could this be a bug on the weblogic plugin ? Please advise.

Rewrite Location-headers in frontend by weblogic plugin

Hi!
I've got a problem where I've got a Apache 2.2.9 acting as a proxy for a application running on BEA Weblogic.
I'm using the plugin from BEA Weblogic as the proxy.
Everything works fine except when the weblogicserver makes a redirect, i.e. sends a Location-header. The Location header looks like "Location: http://weblogic.internal.net/Client".
The servername should be rewritten to the public nam "proxy.example.com".
### START ### Weblogic configuration in apache.conf:
LoadModule weblogic_module /usr/lib/apache2/modules/mod_wl_22.so
<IfModule mod_weblogic.c>
WebLogicHost weblogic.internal.net
WebLogicPort 8202
WLProxySSL on
DebugConfigInfo on
Debug ALL
</IfModule>
<Location /Application/>
SetHandler weblogic-handler
</Location>
### END ### Weblogic configuration in apache.conf:
Any ideas on how to manage the rewrite of the Location-header?
Can weblogic plugin and mod_proxy/mod_rewrite be comined?
Is there any other configuration parameters for weblogic to state the frontend machine?
/Andreas

Hardware Load Balancers and Cluster WebLogic Proxy Plug-in setting

Documentation states that we need to enable the Cluster WebLogic Proxy Plug-in setting when there is a proxy plugin or HttpClusterServlet configured.
We used to have Weblogic Proxy plugin and the setting is still there, also the proxy was replaced by the hardware loadbalancer. Everything works normally and no one complained, but I would assume that WebLogic Proxy Plug-in setting should not be applicable any longer.
Is it possibly harmful to have that setting there? Does it mean that the loadbalancer emulates WebLogic Proxy Plug-in and also need this set?
Thank you

The Weblogic Proxy Plug-in Enabled flag only affects the behavior of a WL proxy module (such as if you were using Apache to proxy to WL via the mod_wl.so module). The value controls what IP address is returned when you call request.getRemoteAddr() from your application. If not enabled, you will get the IP address of the web server that proxied the request. If enabled, you will get the remote client IP address (instead of the proxy IP address) facilitated by the WL-Proxy-Client-IP header. If you are no longer using a plug-in module, the setting will have no affect. Hope this helps...

Weblogic apache plugin and webservices

Can I use the weblogic plugin on a DMZ based Apache server and use a 3 tier architecture
to implement webservices.
Using this model can a external application contact my webservices running in
my internal network and can my weblogic/webservices server contact an external
application/webservices using the same route i.e through the apache webserver
and weblogic plugin.
Any documentation regarding the architecture?

Hi Anil,
Not sure this is possible, unless you are using it as a proxy and setup
the proper host/port mappings, see:
http://edocs.bea.com/wls/docs81/webserv/client.html#1072224
We have a very responsive security newsgroup, you might ask your
configuration question there:
http://newsgroups.bea.com/cgi-bin/dnewsweb?cmd=xover&group=weblogic.developer.interest.security&utag=
Sorry, not much help (SNMH)

I install Weblogic8.1 SP3 which supports for strong cipher suits, and config an apache 2.50 server as an front end.
I config appache to use 2 way SSL with browser and wls one way SSL with apache plugin. Then config apache to forward client certs to WLS. now the problem is, I can see that the SSL connection between browser and apache uses a strong cipher suit('SSL_RSA_WITH_RC4_128_MD5'), but the ssl connection bwtween apache plugin and WLS uses a weak cipher suit('SSL_RSA_EXPORT_WITH_RC4_40_MD5'), with the SnoopServlet, although I use the mod_wl128_20.so module. How can I increase the cipher strength of SSL between WLS and it's apache plugin?
Thanks in advance.
Best

Jean

Hello Gunaseelan,
This is not possible because WLS 6.1 needs a config.xml file, exactly this
name, to start.
What you can do is to define a recovery domain, called myrecovery_domain for
instance, and put the config_recovery.xml, renamed "config.xml".
Hope this helps,
Ludovic.

Hi,
I have 2 weblogic startup scripts (startWebLogic.sh and
startWebLogic_recovery.sh) for the same domain.
startWebLogic.sh uses config.xml file.
I would like to use config_recovery.xml as the configuration file forstartWebLogic_recovery.sh

How would I do this ?
I am using WebLogic Server 6.1 on SunOS 5.8 / HP-UX 11.0.
Appreciate any help.

I am also getting the same problem. I am guessing this is due to the
Eclipse V3.

And i dont find this class at the library?

Weblogic Plugin Configuration Problem -- no more in server list

HELP! Has anyone seen anything like this before. What we are seeing
          is that the plugin sporadically sends requests to the wrong weblogic
          instance. When it sends it to the wrong instance we are seeing the
          following in the wlproxy.log. Like I said, this happens sporadically.
          Sometimes it will work just fine for an entire transaction. Does
          anyone know what the "no more in server list" means. We've had bea on
          the phone for the last 12 hours and they haven't been able to help us
          up to this point. If I need to send any more information please let
          me know....
          Thanks in advance!!!

This one sound stricky. Have you checked all the usual suspects:
          -same cookie name in WB-INF/weblogic.xml and the cookiename set in
          plugin settings (defualts to JSESSIONID in 6.x)
          -network errors between web servers and WLS servers
          That utility can be invaluable in solving problems like this.I have seen
          session settings cause sessions to be lost, but never the message you
          are talking about. Try turning on the "DebugConfigInfo" setting and see
          what the "?__WebLogicBridgeConfig" page can tell you about your
          settings, what server list it is using and what servers are
          primary/secondary. One tip, you need to hit the WLS server one time, and
          then use the "?__WebLogicBridgeConfig". Until it communicates with the
          WLS server, it can only tell you it's own settings and not any
          information about up servers and primary/secondary assignements. Also
          look to make sure each server in the "Server List" has a blue ":OK" next
          to it to signify the plugin can see them.
          Hope that can help, though I am not sure they will deal with the problem
          you are seeing. Make sure you post the outcome to this issue, I will be
          very interested in seeing it.

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.

Single Client Access Name for Weblogic Forms and Reports.

I have a 2 node clustered system:
Windows 2008 R2 64-bit
Weblogic 10.3.3 (on each node)
Weblogic Forms and Reports 11.1.1.3 (on each node)
Database 11gR2 RAC 11.2.0.1 (on each node)
The forms and reports are clustered and I can connect to each from each of the two servers and the cluster is working well.
The database uses Single Client Access Name (SCAN) to present the database as if it were one server called dbserver1.
I was wondering if there was a similar thing for Weblogic and what everyone else uses to present their application as a single name to the user.
I tried using Windows Network Load Balancing, but this stops the database scan listeners from working.
Thanks.

Dear,
Did you find an answer to your question back in 2009?
We are facing the same installation architecture, but we do not find any concrete information regarding SCAN with Oracle Forms 11g

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:

 Any help or suggestions are most helpful

Hello ,
 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

Inforation on Pool tables and cluster tables required.

I want to know about the pool tables and cluster tables like how to create them and how to look the tables associated with the given tables. Like for the table BSEG we have other tables linked BSID etc. I'm new to this concept please guide me.

Pooled Table:
A pooled table in R/3 has a many-to-one relationship with a table in the database (see Figures 3.1 and 3.2). For one table in the database, there are many tables in the R/3 Data Dictionary. The table in the database has a different name than the tables in the DDIC, it has a different number of fields, and the fields have different names as well. Pooled tables are an SAP proprietary construct.
When you look at a pooled table in R/3, you see a description of a table. However, in the database, it is stored along with other pooled tables in a single table called a table pool. A table pool is a database table with a special structure that enables the data of many R/3 tables to be stored within it. It can only hold pooled tables.
R/3 uses table pools to hold a large number (tens to thousands) of very small tables (about 10 to 100 rows each). Table pools reduce the amount of database resources needed when many small tables have to be open at the same time. SAP uses them for system data. You might create a table pool if you need to create hundreds of small tables that each hold only a few rows of data. To implement these small tables as pooled tables, you first create the definition of a table pool in R/3 to hold them all. When activated, an associated single table (the table pool) will be created in the database. You can then define pooled tables within R/3 and assign them all to your table pool.
Pooled tables are primarily used by SAP to hold customizing data.
Cluster Table:
A cluster table is similar to a pooled table. It has a many-to-one relationship with a table in the database. Many cluster tables are stored in a single table in the database called a table cluster.
A table cluster is similar to a table pool. It holds many tables within it. The tables it holds are all cluster tables.
Like pooled tables, cluster tables are another proprietary SAP construct. They are used to hold data from a few (approximately 2 to 10) very large tables. They would be used when these tables have a part of their primary keys in common, and if the data in these tables are all accessed simultaneously.
Table clusters contain fewer tables than table pools and, unlike table pools, the primary key of each table within the table cluster begins with the same field or fields. Rows from the cluster tables are combined into a single row in the table cluster. The rows are combined based on the part of the primary key they have in common. Thus, when a row is read from any one of the tables in the cluster, all related rows in all cluster tables are also retrieved, but only a single I/O is needed.
A cluster is advantageous in the case where data is accessed from multiple tables simultaneously and those tables have at least one of their primary key fields in common. Cluster tables reduce the number of database reads and thereby improve performance.
Restrictions on Pooled and Cluster Tables
1. Pooled and cluster tables are usually used only by SAP and not used by customers, probably because of the proprietary format of these tables within the database and because of technical restrictions placed upon their use within ABAP/4 programs. On a pooled or cluster table:
2. Secondary indexes cannot be created.
3. You cannot use the ABAP/4 constructs select distinct or group by.
4.You cannot use native SQL.
5.You cannot specify field names after the order by clause. order by primary key is the only permitted variation.
For creation of pooled /cluster table, have a look at below link.
