WebLogic JCA
Components
Another major kind of component is the resource
adapter based on the Java connector architecture (JCA). Resource
adapters are a quite complex type of application as they can
establish communication to any sort of backend, support
transactions, and can use any kind of third party protocol for the
communication. They support outgoing and also incoming connections.
This result is another rather complex hierarchy
of MBeans for each connector module. The following script shows a
function which can provide a number of values and information for a
connector module:
def printConnectorRuntimeInformation(applicationName,connectorComponentRuntime):
myName = connectorComponentRuntime.getName()
print '\nFound JCA modul '+myName+' with current state='+
connectorComponentRuntime.getState()+'
and deployment state = ' +
getApplicationComponentState(connectorComponentRuntime)
# connection pools
myConPools = connectorComponentRuntime.getConnectionPools()
for myNextCon in myConPools:
print 'ConncetionPool: Name='+myNextCon.getName()+
'
State='+myNextCon.getState()+
' testable='+str(myNextCon.isTestable())+
'
TransactionSupport='+myNextCon.getTransactionSupport()
See the book code download for full
script
print '
ActiveCurrentCount='
+str(myNextCon.getActiveConnectionsCurrentCount())+
' ActiveHighCount='+str(myNextCon.getActiveConnectionsHighCount())+
'
FreeCurrentCount='+str(myNextCon.getFreeConnectionsCurrentCount())+
'
FreeHighCount='+str(myNextCon.getFreeConnectionsHighCount())+
' AverageActiveUsage='+str(myNextCon.getAverageActiveUsage())
Note that line breaks have in inserted here for
better presentation. For the execution of the script, those must be
removed.
The following listing provides an impression
about the complexity of a connector component and its sub MBeans. In
this case, the connection pool:
