Configure new JMS connections using wsadmin.sh

Use the wsadmin scripting tool to configure a new JMS connection.

Before starting this task, wsadmin must be running. Configure a new JMS connection:

In the following examples, code blocks beginning with wsadmin> show code that is entered by the user. Lines that do not begin with wsadmin> show code that has been returned by the console.

1. Identify the parent ID:
   • Jacl:
     wsadmin>set newjmsp [$AdminConfig getid /Cell:mycell/Node:myNode/JMSProvider:JMSP1]
   • Using Jython:

     wsadmin>newjmsp = AdminConfig.getid('/Cell:mycell/Node:myNode/JMSProvider:JMSP1')
     wsadmin>print newjmsp

   Example output:

   JMSP1(cells/mycell/nodes/mynode|resources.xml#JMSProvider_1)
2. Get required attributes:
   • Jacl:
     wsadmin>$AdminConfig required GenericJMSConnectionFactory
   • Using Jython:
     wsadmin>print AdminConfig.required('GenericJMSConnectionFactory')

   Example output:

   Attribute       Type
   name       String
   jndiName    String
   externalJNDIName  String

3. Set up required attributes:
   • Jacl:

     wsadmin>set name [list name JMSCF1]
     wsadmin>set jndi [list jndiName jms/JMSConnFact1]
     wsadmin>set extJndi [list externalJNDIName jms/extJMSCF1]
     wsadmin>set jmscfAttrs [list $name $jndi $extJndi]

     Example output:

     {name JMSCF1} {jndiName jms/JMSConnFact1} {externalJNDIName jms/extJMSCF1}
   • Using Jython:

     wsadmin>name = ['name', 'JMSCF1']
     wsadmin>jndi = ['jndiName', 'jms/JMSConnFact1']
     wsadmin>extJndi = ['externalJNDIName', 'jms/extJMSCF1']
     wsadmin>jmscfAttrs = [name, jndi, extJndi]
     wsadmin>print jmscfAttrs

     Example output:

     [[name, JMSCF1], [jndiName, jms/JMSConnFact1], [externalJNDIName, jms/extJMSCF1]]

4. Create generic JMS connection factory and assign it to a variable. In this example the variable is cf:
   • Jacl:
     wsadmin>set cf [$AdminConfig create GenericJMSConnectionFactory $newjmsp $jmscfAttrs]
   • Using Jython:

     wsadmin>cf = AdminConfig.create('GenericJMSConnectionFactory', newjmsp, jmscfAttrs)
     wsadmin>print cf

   Example output:

   JMSCF1(cells/mycell/nodes/mynode|resources.xml#GenericJMSConnectionFactory_1)

5. Configure a connection pool for the generic connection factories.

   Because Java 2 Connector (J2C) manages the generic connection factories, configure a connection pool to indicate the policy for connection management by J2C. Use the variable assigned to your generic connection factory to include it in the connection pool. The following example commands configure a connection pool in the environment:

   • Jacl:

     wsadmin>set connectionPool [$AdminConfig create ConnectionPool $cf {} connectionPool]
     wsadmin>set sessionPool [$AdminConfig create ConnectionPool $cf {} sessionPool]

   • Using Jython:

     wsadmin>connectionPool = AdminConfig.create('ConnectionPool', cf,'', 'connectionPool')
     wsadmin>sessionPool = AdminConfig.create('ConnectionPool', cf, '', 'sessionPool')

6. Save the configuration changes.
