<h6><a name="datatestexconfig"></a>Example: Test a connection using testConnection(ConfigID)</h6>
|
||
|
|
|
||
|
|
<p>You can pass the configuration ID of a configured data source, rather
|
||
|
|
than the properties of the data source. This example program uses Java Management Extensions (JMX) to connect
|
||
|
|
to a running server and invoke the testConnection method on the DataSourceCfgHelper MBean.</p>

/**
|
||
|
|
* Description
|
||
|
|
* Resource adapter test program to make sure that the MBean interfaces work.
|
||
|
|
* Following interfaces are tested
|
||
|
|
*
|
||
|
|
* --- testConnection()
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* We need following to run
|
||
|
|
*
|
||
|
|
* From an iSeries command line:
|
||
|
|
*
|
||
|
|
* -> QSHELL (Start the QSHELL environment)
|
||
|
|
*
|
||
|
|
* -> cd (yourDirectory)
|
||
|
|
* (change current directory to the directory that holds the java source)
|
||
|
|
*
|
||
|
|
* -> javac -extdirs /QIBM/ProdData/WebASE51/ASE/lib -d . testDSGUI.java
|
||
|
|
* (compile the testDSGUI class)
|
||
|
|
*
|
||
|
|
* -> . /QIBM/ProdData/WebASE51/ASE/bin/setupClient
|
||
|
|
* (produce the $JAVA_FLAGS_EXT environment variable)
|
||
|
|
*
|
||
|
|
* -> java $JAVA_FLAGS_EXT testDSGUI
|
||
|
|
* (call the program)
|
