Define process groups for a service

Before you begin

Review Define services and process groups.


To define process groups for a service:

  1. Complete the steps described in Define general properties for a service to define the general properites of a service.
  2. Click Add process group on the Process Requirements page to add a process group for the service.
  3. Select one of the following methods to define the process group:
    Method Description

    Start from Scratch

    Create a process group from scratch. You specify the following information:

    • Process group properties.

    • JVM template parameters that are used when creating the JVM instances initially.

    • Ready metrics that specify when an process instance is available as a resource.

    Import from another Service

    Import the process group configutation from another service.

    Import from a Running WebLogic Domain

    Import the process group configuration from a running WebLogic domain by specifying its connection properties. For best results, import configuration data from the Administration server of the WebLogic domain rather than a Managed server.

    Import from a WebLogic Domain Configuration

    Import the process group configuration from a WebLogic domain configuration by specifying its path name.
  4. Click Next.
  5. If you selected Start from Scratch, set the following fields and skip to Step 9.

    Define the process group properties.

    Field Description

    Process Group

    Name of the process group.

    Number of processes

    Number of processes that are configured for the process group when it is initially created.

    Define the process group template parameters that are used to configure the inital process instances for the process group. You can edit the processes that are configured initially to update any of the values.

    Field Description

    Name

    Name of the instance. The first process instance uses this name. For each additional process instance that is configured, a numeric suffix is added to the name starting with 1 and incrementing by 1 for each additional process instance.

    Description

    Description of the instance.

    Main Class

    Name of the fully qualified Java class to be invoked.

    Main JAR

    Name of the JAR file that contains the class and resource files for the application to be invoked.

    Host

    Name of the host. The host and port address are used to access the JMX artifacts of the instance for monitoring.

    Starting Port#

    Port address. The first process instance uses this port number. For each additional process instance that is configured initially, the port address is incremented by 1.

    Note: You should ensure that the resulting port address values are consistent with existing application configurations. For example, for a WebLogic instance, the port address is defined in the domain configuration file (config.xml).

    Classpath

    Value of CLASSPATH for the domain.

    The following provides guidelines for setting the CLASSPATH value for plain and ESX Agents.

    Plain Agents

    • For WebLogic domains, the CLASSPATH is set by invoking DOMAIN_NAME\bin\setDomainEnv.cmd (setDomainEnv.sh on UNIX) in your domain, where DOMAIN_NAME is the directory in which you located the domain; for example, WL_HOME\user_projects\domains\DOMAIN_NAME, and where WL_HOME is the location in which you installed WebLogic Server. Once set, you can echo the CLASSPATH value obtain the classpath value.

    • For generic Java applications, set the CLASSPATH based on the application installation on the plain agent host. For example (Windows): c:\applications\myapp\lib\myapp1.jar; C:\applications\myapp\lib\myapp2.jar

    ESX Agents (LVM File System)

    • If the element is in the ISO, then the path must begin with /appliance, where the ISO is mounted.

    • If the element is in an NFS share, then the path must begin with the NFS mount point. If the element is in the local disk, then the path would begin with /.

    • WLS-VE 9.2v1.0 standard classpath (as set by the commonStartVE script): /bea/patch_weblogic921/profiles/default/sys_manifest_classpath/weblogic_patch.jar:/appliance/java/lib/tools.jar:/appliance/bea/weblogic92/server/lib/weblogic.jar:/appliance/bea/weblogic92/server/lib/webservices.jar

    • WLS-VE 9.2v1.1 standard classpath (as set by the commonStartVE script): /bea/patch_weblogic922/profiles/default/sys_manifest_classpath/weblogic_patch.jar:/appliance/java/lib/tools.jar:/appliance/bea/weblogic92/server/lib/weblogic.jar:/appliance/bea/weblogic92/server/lib/webservices.jar

    • Example generic Java application on LVM (including NFS, Local Disk, and ISO paths): /mynfs/patches/myapp_patch1.jar:/patches/myapp_patch2.jar:/appliance/applications/myapp/lib/myapp1.jar:/appliance/applications/myapp/lib/myapp2.jar

    JVM Arguments

    		 Standard options that are passed to the java command.

    Java Arguments

    		 Java arguments that are passed to the Java Main method. Separate each Java argument using a space.

    UserName

    		 User name for authenticating JMX connections.

    Password

    		 Password for authenticating JMX connections.

    Instance Directory

    		 Working directory in which the process instance is started.

    Native Lib Directory

    		 Path to the native libraries.

    Use Native JMX

    		 Flag that specifies whether to use the JVM's native JMX MBean server.

    SSH Enabled

    		 Flag that specifies whether SSH is enabled for the instance.

    Protocol

    		 Protocol used for JMX connections. Select a value from the drop-down list. Valid values include: iiop, iiops, http, and https.

    Define the ready metrics that are used to determine if an instance is completely initialized and ready for service. Ready metrics are optional, but useful for determining when a process is available.

    Field Description
