Testing JDBC Data Sources using Jython

One of my colleagues asked me about this …

In essence, did I have a Jython script that allows one to test JDBC data source …

Here's one I prepared earlier: -


cellID = AdminControl.getCell()
cell=AdminConfig.getid( '/Cell:'+cellID+'/')
for dataSource in AdminConfig.list('DataSource',cell).splitlines():
 print dataSource

Notes: -

- To support the FOR loop, there are indentations ( thanks Python, we love you ) in front of the last two lines of the script
- Similarly, there's a spare, blank line ( again, thanks, Python ) at the end of the script to finish the loop

When I run this: -

I do get an exception, for which I'm NOT catching: -

specifically this: -

WASX7017E: Exception received while running file "testDataSource.jy"; exception information:
java.sql.SQLException: java.sql.SQLException: Database '/opt/ibm/WebSphereProfiles/AppSrv01/databases/EJBTimers/AppClusterMember1/EJBTimerDB' not found. DSRA0010E: SQL State = XJ004, Error Code = 40,000

I could mitigate that by adding the appropriate try/catch logic to my script - that's tomorrow's challenge.

For the record, this exception occurs against a datasource about which I don't care :-)
