Use the manageBBSON.py script to gather the BBSON bulletin board usage statistics, and periodically dump BBSON states. The statistics are available in the standard output and trace log files.
For problem diagnosis and debugging purposes, use the manageBBSON.py script to collect BBSON state dumps from every process in the product cell.
The manageBBSON.py script is in the app_server_root/bin directory.
For transitioning users: The WebSphere Virtual Enterprise command that equates to manageBBSON.py is manageWVEBB.py. If we are making the transition from WebSphere Virtual Enterprise, we can continue to use the manageWVEBB.py command, which operates the same as the manageBBSON.py command.trns
Run the following command on each Intelligent Management cell:
wsadmin -f manageBBSON.py operation [nodeName serverName]
Specify the operation variable, which can be one of the following choices:
- dump: Dumps the state of the bulletin board
- getsnapshot: Obtains statistics about the current state of the bulletin board
- getStatisticsPrintInterval: Shows the current interval between printing bulletin board statistics in seconds
- setStatisticsPrintInterval: Sets the interval between printing bulletin board statistics in seconds
If we do not specify the [nodeName serverName] argument, the MBean is invoked against every process in the cell. Provide a node name and server name to narrow the invocation to the specific node and server listed.
