3 1. Configuring WebLogic Server 1.1 Introduction This chapter provides a step by step process to configure Weblogic Server. To start with, the chapter provides a brief description on the following: Domain Domain Weblogic Domain Structure Administrator Server Managed Server Managed Server Cluster Node Manager A domain is the basic administration unit for WebLogic Server instances. A domain consists of one or more WebLogic Server instances (and their associated resources) that you manage with a single Administration Server. You can define multiple domains based on different system administrators' responsibilities, application boundaries, or geographical locations of servers. Conversely, a single domain can be used to centralize all WebLogic Server administration activities. Each WebLogic Server domain must have one server instance that acts as the Administration Server. You use the Administration Server, via the Administration Console or using the command line in order to configure all other server instances and resources in the domain WebLogic Domain Structure 1-1

4 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 Administration Server. The Administration Server provides a central point for managing the domain and providing access to the WebLogic Server administration tools. These tools include the following: Managed Server WebLogic Server Administration Console: Graphical user interface to the Administration Server. WebLogic Server Node Manager: A Java program that lets you start and stop server instances both Administration Servers and Managed Servers remotely, and to monitor and automatically restart them after an unexpected failure. In a domain, server instances other than the Administration Server are referred to as Managed Servers. 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 the domain'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 the administration server and managed server Managed Server Cluster Two or more Managed Servers can be configured as a WebLogic Server cluster to increase application scalability and availability. In a WebLogic Server cluster, most resources and services are deployed to each Managed Server (as opposed to a single Managed Server,) enabling failover 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 Node Manager The Managed Servers in a production WebLogic Server environment are often distributed across multiple machines and geographic locations. Node Manager is a Java utility that runs as separate process from WebLogic Server and allows you to perform common operations tasks for a Managed Server, regardless of its location with respect to its Administration Server. While use of Node Manager is optional, it provides valuable benefits if your WebLogic Server environment hosts applications with high availability requirements. If you run Node Manager on a machine that hosts Managed Servers, you can start and stop the Managed Servers remotely using the Administration Console or from the command line. Node Manager can also automatically restart a Managed Server after an unexpected failure. 1-2

5 1.2 Domain Creation The following sections provides step-by-step WebLogic Server configuration for Oracle FCUBS covering: Managed server Creation Cluster Creation Node Creation This example, helps you to create a domain with 2 managed servers. The managed servers are going to be created on 2 different physical servers (nodes). This requires Weblogic Server of same version to be installed on both the machines and services (Weblogic and node manager) should be up Environment details This document has been prepared based on a test conducted in Linux servers running Red Hat Enterprise Linux Server release 5.5 (Tikanga). The machine configuration is given below, Node1 Hostname: IPL187DOR IP Address: CPU details: 8 core Intel(R) Xeon(R) CPU 2.53GHz Physical memory: 24GB Node2 Hostname: IPL186DOR IP Address: CPU details: 8 core Intel(R) Xeon(R) CPU 2.53GHz Physical memory: 24GB Start Node Manager Start node manager in both servers before creating domain. Any domain created before creation of Node Manager Service will not be accessible via node Manager (even after restarting node manager), 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 be enrolled against the Node Manager. The Node Manager should automatically be 'reachable' by the domain. 1-3

6 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 script under $WLSHOME/server/bin directory to start Nodemanager. In IPL186DOR, In IPL187DOR, 1-4

7 1.2.3 Enable Graphical User Interface (GUI) Establish a telnet or SSH connection to server. Start X-manager in windows desktop. Export DISPLAY environment variable to the machine IP where x-manager is running. Syntax: export DISPLAY=<ip-address>:<port> Example: export DISPLAY= :0.0 Test using xclock, Fusion Middleware Configuration Wizard Weblogic domain creation and configuration will be done from server From server launch fusion Middleware configuration wizard using config.sh under $WLS_HOME/common/bin directory, 1-5

8 1-6

9 Choose Create a new Weblogic domain option. Click on Next, 1-7

10 Select Domain Source. Click on Next, 1-8

11 Specify Domain Name and location. Click on Next, 1-9

12 Configure Administrator User Name and password Use this screen to define the default WebLogic Administrator account for the domain. This account is used to boot and connect to the domain's Administration Server. Note: This is the credentials used to access Administration console. Click on Next, Select Server Start Mode as production mode and choose JDK. Click on next, 1-10

13 1-11

14 Select the options Administration Server and Managed Servers, Clusters and Machines. Click next, 1-12

15 Configure Administration server Listen address and port Note: The default Listen port is This could be changed to any other free port. Please make a 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. 1-13

16 Configure Managed Server Note: Every 75 concurrent users require one managed server. I.e. for 300 concurrent FCUBS users, 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. 1-14

17 Cluster configuration, Click on Add button to add a new cluster. Input the cluster name. Choose multicast option for Cluster messaging mode. Note: The default multicast address and port will be and 7001 respectively. A different address and port can be chosen if it is already in use. 1-15

18 Select the managed servers in the left pane and assign them to the cluster by clicking the right arrow button. 1-16

19 After assigning managed servers to cluster, That completes Cluster configuration. On clicking next, the machine configuration screen is displayed. 1-17

20 Configure machines Click on Add button to add the desired number of nodes. 1-18

21 Assign managed servers to Nodes In this scenario, based on the host on which the managed server is created, the managed servers are 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 and listen to port 8991 & Managed server fcubs2 will start in server and listen to port This completes the Machine creation and configuration. Click Next. Verify the details. Click on Create button to create domain, 1-19

22 This completes the domain creation. 1-20

23 The Admin Server console will be something like: address>:<admin console port>/console <IP address >: Host on which domain was created. <admin console port> : The port specified at the Administration Server configuration page. In this case the Admin Console URL is: Pack and unpack domain The domain structure is expected to be copied to the second server (IPL186DOR) during domain creation. In some cases the domain structure (domain directories and scripts) will not be copied to the second node (IPL186DOR) of the weblogic clusters. Use pack and unpack utility provided under $WLSHOME//common/bin, Pack: Domain in server, 1-21

24 ./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 under /tmp area and unpack the 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 32 bit 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, 1-22

25 ./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 both servers. 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 1-23

26 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. 1-24

27 1.5 Managed server startup using script (startweblogic.sh) It is recommended to start managed servers using scripts (startweblogic.sh) when the managed servers are started from weblogic console. To enable this set the following properties in Nodemanager.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/startWebLogi c.sh Nodemanager.properties can be found under $WLSHOME/ common/ nodemanager In server Nodemanager.properties location: /oraint2/middleware/wls1035/wlserver_10.3/common/nodemanager/ Nodemanager.properties Under server, 1-25

28 Nodemanager.properties location: /oraint1/weblogic10.5/oracle/middleware/wlserver_10.3/common/nodemanager Note: Node manager must be restarted in all servers ( & ) to activate this setting 1-26

29 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 <pid> 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 Starting Admin server Use startweblogic.sh under $DOMAIN_HOME/bin to start admin server in server, 1-27

30 In this example startweblogic.sh script is under /oraint2/middleware/wls1035/user_projects/domains/fcubscl/bin/ under server Note: Refer Appendix A on possible admin server start-up problems. 1-28

31 1.7 Starting managed servers Login to Administration console using URL User name and password is set during domain creation as follows, Username: weblogic Password: weblogic

32 This screen provides details of both managed servers which are currently down. Both managed servers are part of FCUBSCL domain. Fcubs1 managed server is associated with machine1 that is server. Machine for fcubs2 managed server is machine2 that is

33 1.7.1 Verifying machine status Before starting the managed servers ensure that all the machines are reachable, Domain structure -> Machines -> machine1 -> Monitoring -> node Manager Status Domain structure -> Machines -> machine2 -> Monitoring -> node Manager Status Node manager Status should be Reachable Select the managed servers and click on start button to start the managed server, Domain structure -> Environment -> servers -> control 1-31

34 Managed server Status will be changed to running, 1-32
