Configure EJB containers using wsadmin

We can use the AdminConfig object or the wsadmin script library to configure EJB containers in the configuration.
There are two ways to perform this task. Complete the steps in this topic to use the AdminConfig object to modify your EJB container configuration. Alternatively, you can use the configureEJBContainer Jython script in the AdminServerManagement script library to configure EJB containers. The wsadmin tool automatically loads the script when the tool starts. Use the following syntax to configure EJB containers using the configureEJBContainer script:
AdminServerManagement.configureEJBContainer(nodeName, serverName, ejbName, passivationDir,  defaultDatasourceJNDIName)
For additional information and argument definitions, see the documentation for the AdminServerManagement script library.

Procedure
Start wsadmin.sh.
Identify the application server of interest.
The following examples identify the application server and assign it to the serv1 variable:
### Jacl
set serv1 [$AdminConfig getid /Cell:mycell/Node:mynode/Server:server1/]
### Jython
serv1 = AdminConfig.getid('/Cell:mycell/Node:mynode/Server:server1/')
print serv1
The previous commands consist of the following elements:

Command elements. The following table explains elements in the Jacl and Jython examples:
Element Description
set Jacl command
serv1 Variable name
$ Jacl operator for substituting a variable name with its value
AdminConfig Object representing the application server configuration
getid AdminConfig command
/Cell:mycell/Node:mynode/Server:server1/ The hierarchical containment path of the configuration object
Cell Object type
mycell Optional name of the object
Node Object type
mynode Optional name of the object
Server Object type
server1 Optional name of the object

Example output:
server1(cells/mycell/nodes/mynode/servers/server1|server.xml#Server_1)
Identify the EJB container that belongs to the server.
The following example identifies the EJB container for the server of interest and assigns it to the ejbc1 variable:
### Jacl
set ejbc1 [$AdminConfig list EJBContainer $serv1]
### Jython
ejbc1 = AdminConfig.list('EJBContainer', serv1)
print ejbc1
The previous commands consist of the following elements:

Command elements. The following table explains elements in the Jacl and Jython examples:
Element Description
set Jacl command
ejbc1 Variable name
$ Jacl operator for substituting a variable name with its value
AdminConfig The object that represents the application server configuration
list AdminConfig command
EJBContainer The object type
The name of the object type that you specify is the one based on the XML configuration files and does not have to be the same name that the admin console displays.
serv1 Evaluates to the ID of the server of interest

Example output:
(cells/mycell/nodes/mynode/servers/server1|server.xml#EJBContainer_1)
View each of the attributes of the EJB container.
The following example displays the EJB container attributes but does not display nested attributes:
### Jacl
$AdminConfig show $ejbc1
Example output:
{cacheSettings (cells/mycell/nodes/mynode/servers/
server1|server.xml#EJBCache_1)}
{components {}}
{inactivePoolCleanupInterval 30000}
{parentComponent (cells/mycell/nodes/mynode/servers/
server1|server.xml#ApplicationServer_1)
{passivationDirectory ${USER_INSTALL_ROOT}/temp}
{properties {}}
{services {(cells/mycell/nodes/mynode/servers/
server1|server.xml#MessageListenerService_1)}
{stateManagement (cells/mycell/nodes/mynode/servers/
server1|server.xml#StateManageable_10)}
### Jython
print AdminConfig.show(ejbc1)
Example output:
[cacheSettings (cells/mycell/nodes/myode/servers/
server1|server.xml#EJBCache_1)]
[components []]
[inactivePoolCleanupInterval 30000]
[parentComponent (cells/mycell/nodes/myode/servers/
server1|server.xml#ApplicationServer_1)
[passivationDirectory ${USER_INSTALL_ROOT}/temp]
[properties []]
[services [(cells/mycell/nodes/myode/servers/
server1|server.xml#MessageListenerService_1)]
[stateManagement (cells/mycell/nodes/mynode/servers/
server1|server.xml#StateManageable_10)]

Command elements. The following table explains elements in the Jacl and Jython examples:
Element Description
$ Jacl operator for substituting a variable name with its value
print Jython command
AdminConfig The object that represents the application server configuration
showall AdminConfig command
ejbc1 evaluates to the ID of the enterprise bean container
The following example displays the EJB container attributes, including nested attributes:
### Jacl
$AdminConfig showall $ejbc1
Example output:
{cacheSettings {{cacheSize 2053}
  {cleanupInterval 3000}}}
{components {}}
{inactivePoolCleanupInterval 30000}
{parentComponent (cells/mycell/nodes/mynode/servers/
server1|server.xml#ApplicationServer_1)}
{passivationDirectory ${USER_INSTALL_ROOT}/temp}
{properties {}}
{services {{{context (cells/mycell/nodes/mynode/servers/
server1|server.xml#EJBContainer_1)}
  {listenerPorts {}}
  {properties {}}
  {threadPool {{inactivityTimeout 3500}
    {isGrowable false}
    {maximumSize 50}
    {minimumSize 10}}}}}}
{stateManagement {{initialState START}
  {managedObject (cells/mycell/nodes/mynode/servers/
server1|server.xml#EJBContainer_1)}}}
### Jython
print AdminConfig.showall(ejbc1)
Example output:
[cacheSettings [[cacheSize 2053]
  [cleanupInterval 3000]]]
[components []]
[inactivePoolCleanupInterval 30000]
[parentComponent (cells/mycell/nodes/mynode/servers/
server1|server.xml#ApplicationServer_1)]
[passivationDirectory ${USER_INSTALL_ROOT}/temp]
[properties []]
[services [[[context (cells/mycell/nodes/mynode/servers/
server1|server.xml#EJBContainer_1)]
  [listenerPorts []]
  [properties []]
  [threadPool [[inactivityTimeout 3500]
    [isGrowable false]
    [maximumSize 50]
    [minimumSize 10]]]]]]
[stateManagement {{initialState START]
  [managedObject (cells/mycell/nodes/mynode/servers/
server1|server.xml#EJBContainer_1)]]]
