1. Configuring WebLogic Server

1.1 IntroductionThis chapter provides a step by step process to configure Weblogic Server. To start with, thechapter provides a brief description on the following:

Domain

Weblogic Domain Structure

Administrator Server

Managed Server

Managed Server Cluster

Node Manager

1.1.1 Domain

A domain is the basic administration unit for WebLogic Server instances. A domain consists ofone or more WebLogic Server instances (and their associated resources) that you manage with asingle Administration Server. You can define multiple domains based on different systemadministrators' responsibilities, application boundaries, or geographical locations of servers.Conversely, a single domain can be used to centralize all WebLogic Server administrationactivities.

Each WebLogic Server domain must have one server instance that acts as the AdministrationServer. You use the Administration Server, via the Administration Console or using the commandline in order to configure all other server instances and resources in the domain.

1.1.2 WebLogic Domain Structure


4/69

1-2

1.1.3 Administration Server

A domain includes one WebLogic Server instance that is configured as an Administration Server. All changes to configuration and deployment of applications are done through the AdministrationServer.

The Administration Server provides a central point for managing the domain and providing accessto the WebLogic Server administration tools. These tools include the following:

WebLogic Server Administration Console: Graphical user interface to the AdministrationServer.

WebLogic Server Node Manager: A Java program that lets you start and stop serverinstances—both Administration Servers and Managed Servers—remotely, and to monitorand automatically restart them after an unexpected failure.

1.1.4 Managed Server

In a domain, server instances other than the Administration Server are referred to as ManagedServers. Managed servers host the components and associated resources that constitute your

applications—for example, JSPs and EJBs. When a Managed Server starts up, it connects to thedomain's Administration Server to obtain configuration and deployment settings.

In a domain with only a single WebLogic Server instance, that single server works as both theadministration server and managed server.

1.1.5 Managed Server Cluster

Two or more Managed Servers can be configured as a WebLogic Server cluster to increaseapplication scalability and availability. In a WebLogic Server cluster, most resources and servicesare deployed to each Managed Server (as opposed to a single Managed Server,) enablingfailover and load balancing.

The servers within a cluster can either run on the same machine or reside in different machines.To the client, a cluster appears as a single WebLogic Server instance.

1.1.6 Node Manager

The Managed Servers in a production WebLogic Server environment are often distributed acrossmultiple machines and geographic locations.

Node Manager is a Java utility that runs as separate process from WebLogic Server and allowsyou to perform common operations tasks for a Managed Server, regardless of its location withrespect to its Administration Server. While use of Node Manager is optional, it provides valuablebenefits if your WebLogic Server environment hosts applications with high availabilityrequirements.

If you run Node Manager on a machine that hosts Managed Servers, you can start and stop theManaged Servers remotely using the Administration Console or from the command line. NodeManager can also automatically restart a Managed Server after an unexpected failure.

1.2 Domain Creation

The following sections provides step-by-step WebLogic Server configuration for Oracle FCUBScovering:

Managed server Creation

Cluster Creation

Node Creation

This example, helps you to create a domain with 2 managed servers. The managed servers aregoing to be created on 2 different physical servers (nodes). This requires Weblogic Server ofsame version to be installed on both the machines and services (Weblogic and node manager)should be up.

1.2.1 Environment details

This document has been prepared based on a test conducted in Linux servers running Red HatEnterprise Linux Server release 5.5 (Tikanga). The machine configuration is given below,

Node1

Hostname: IPL187DOR

IP Address: 10.184.74.187

CPU details: 8 core Intel(R) Xeon(R) CPU E5540 @ 2.53GHz

Physical memory: 24GB

Node2

Hostname: IPL186DOR

IP Address: 10.184.74.186

CPU details: 8 core Intel(R) Xeon(R) CPU E5540 @ 2.53GHz

Physical memory: 24GB

1.2.2 Start Node Manager

Start node manager in both servers before creating domain. Any domain created before creationof Node Manager Service will not be accessible via node Manager (even after restarting nodemanager), solution is to run the WLST command “nmEnroll” to enroll that domain with the Node

Manager.

If the domain is created after the Node Manager Service has been installed should not have to beenrolled against the Node Manager. The Node Manager should automatically be 'reachable' bythe domain.

1-4

How to check whether nodemanager is already running?

The way to verify the nodemanager status is to check whether node manager process is running.

ps –ef|grep weblogic.nodemanager.javaHome

If the above command returns the process details then node manager is running.

If nodemanager is not running in any of the server, start it using startNodeManager.sh scriptunder $WLSHOME/server/bin directory to start Nodemanager.

In IPL186DOR,

In IPL187DOR,

1.2.3 Enable Graphical User Interface (GUI)

Establish a telnet or SSH connection to 10.184.74.187 server. Start X-manager in windowsdesktop. Export DISPLAY environment variable to the machine IP where x-manager is running.

Syntax: export DISPLAY=:

Example: export DISPLAY=10.184.86.240:0.0

Test using xclock,

1.2.4 Fusion Middleware Configuration Wizard

Weblogic domain creation and configuration will be done from server 10.184.74.187.

From server 10.184.74.187 launch fusion Middleware configuration wizard using config.sh under$WLS_HOME/common/bin directory,

Select the options Administration Server and Managed Servers, Clusters and Machines. Clicknext,


15/69

1-13

Configure Administration server Listen address and port

Note: The default Listen port is 7001. This could be changed to any other free port. Please makea note of this port; it’s essential for launching the Admin console post domain creation.

In this configuration 8990 port is input.

This completes Admin Server configuration.

The next screen takes us to Managed Server configuration.


16/69

1-14

Configure Managed Server

Note: Every 75 concurrent users require one managed server. I.e. for 300 concurrent FCUBSusers, it is recommended to have 4 managed servers.

Click on Add button to add the desired number of Managed Servers.

This completes managed server configurations.

The next screen takes us to Cluster creation and configuration.


17/69

1-15

Cluster configuration,

Click on Add button to add a new cluster. Input the cluster name. Choose multicast option forCluster messaging mode.

Note: The default multicast address and port will be 239.192.0.0 and 7001 respectively. Adifferent address and port can be chosen if it is already in use.

Assign managed servers to Nodes

In this scenario, based on the host on which the managed server is created, the managed serversare assigned to respective Nodes.

Select the managed Server(s) in the left pane and assign them to the desired Node by clicking

the right arrow button.

As per the above configuration, managed server fcubs1 will start in server 10.184.74.187 andlisten to port 8991 & Managed server fcubs2 will start in server 10.184.74.186 and listen to port8992.

This completes the Machine creation and configuration. Click Next.

Verify the details. Click on “Create” button to create domain,


22/69


23/69

1-21

The Admin Server console will be something like:

http://:/console

: Host on which domain was created.

: The port specified at the Administration Server configuration page.

In this case the Admin Console URL is: http://10.184.74.187:8990/console

1.3 Pack and unpack domain

The domain structure is expected to be copied to the second server (IPL186DOR) during domaincreation. In some cases the domain structure (domain directories and scripts) will not becopied to the second node (IPL186DOR) of the weblogic clusters. Use pack and unpack utility

provided under $WLSHOME//common/bin,

Pack: Domain in 10.184.74.187 server,


24/69

1-22

./pack.sh -managed=true -domain=/oraint2/middleware/wls1035/user_projects/domains/FCUBSCL -template=/tmp/FCUBSCL.jar -template_name="FCUBSCL"

Unpack: FTP FCUBSCL.jar in binary mode to server 10.184.74.186 under /tmp area and unpackthe domain using unpack utility provided under $WLSHOME//common/bin,

./unpack.sh -domain=/oraint1/weblogic10.5/Oracle/Middleware/user_projects/domains/FCUBSCL-template=/tmp/FCUBSCL.jar

1.4 JVM Tuning

This section of the document provides JVM optimization for Oracle FLEXCUBE UBS.

Basically the JAVA minimum and maximum head size needs to be reset for 32 and 64 bit

environments. Both the minimum and maximum heap size is set to 1.5GB and 2GB in case of 32bit and 64 bit environments respectively.

How to find whether the JVM is 32bit or 64bit?

Go to $JAVA_HOME/bin directory. Check java version using,


25/69

1-23

./java –d64 –version

64 bit JVM shows the version details where as 32bit throws an error.

To change the JVM heap parameters modify setDomainEnv.sh under domain FCUBSCL in bothservers.

This file is located at “$WL_HOME/user_projects/domains/$WLS_DOMAIN/bin”

Use USER_MEM_ARGS variable to override the standard memory arguments passed to java.

32 bit JVM:

USER_MEM_ARGS=”-Xms1536M –Xmx1536M –XX:MaxPermSize=512M”

export USER_MEM_ARGS

64 bit JVM:

USER_MEM_ARGS=”-Xms2048M –Xmx2048M –XX:MaxPermSize=512M”

export USER_MEM_ARGS

In server IPL187DOR,

File setDomain.sh under directory/oraint2/middleware/wls1035/user_projects/domains/FCUBSCL/bin


26/69

1-24

In server IPL186DOR,

File setDomain.sh under directory/oraint1/weblogic10.5/Oracle/Middleware/user_projects/domains/FCUBSCL/bin

Note: Take a backup of the file before editing the same.


27/69

1-25

1.5 Managed server startup using script (startWeblogic.sh)

It is recommended to start managed servers using scripts (startWeblogic.sh) when the managedservers are started from weblogic console. To enable this set the following properties inNodemanager.properties file in both servers,

StartScriptEnabled=true

StartScriptName=$DOMAIN_HOME/bin/startWebLogic.sh

Example:

StartScriptEnabled=true

StartScriptName=/oraint2/middleware/wls1035/user_projects/domains/fcubs113/bin/startWebLogic.sh

Nodemanager.properties can be found under $WLSHOME/ common/ nodemanager

In server 10.184.74.187

Nodemanager.properties location:/oraint2/middleware/wls1035/wlserver_10.3/common/nodemanager/ Nodemanager.properties

Under 10.184.74.186 server,


28/69

1-26

Nodemanager.properties location:

/oraint1/weblogic10.5/Oracle/Middleware/wlserver_10.3/common/nodemanager

Note: Node manager must be restarted in all servers (10.184.74.187 & 10.184.74.186) toactivate this setting


29/69

1-27

How to restart node manager?

Find out node manager pid using ps -ef|grep weblogic.nodemanager.javaHome

Change directory to $WLSHOME/server/bin

Kill the unix process using kill -9

Verify that the node manager is killed by tail –f nohup.out

Start node manager using nohup ./startNodeManager.sh &

Verify nodemanager is started using tail –f nohup.out

Same way restart nodemanager in server 10.184.74.186.

1.6 Starting Admin server

Use startWeblogic.sh under $DOMAIN_HOME/bin to start admin server in 10.184.74.187 server,


30/69

1-28

In this example startWeblogic.sh script is under/oraint2/middleware/wls1035/user_projects/domains/FCUBSCL/bin/ under server 10.184.74.187

Note: Refer Appendix A on possible admin server start-up problems.


31/69

1-29

1.7 Starting managed servers

Login to Administration console using URL http://10.184.74.187:8990/console,

User name and password is set during domain creation as follows,

Username: weblogic

Password: weblogic123

http://10.184.74.187:8990/consolehttp://10.184.74.187:8990/consolehttp://10.184.74.187:8990/consolehttp://10.184.74.187:8990/console


32/69
