manageWVEBB.py script

You can use the manageWVEBB.py script to gather the statistics usage of the BBSON bulletin board and periodically dump BBSON states. The statistics are available in the standard output and trace log files.

Purpose

For problem diagnosis and debugging purposes, use the manageWVEBB.py script to collect BBSON state dumps from every process in the product cell.

Location

The manageWVEBB.py script is in the install_root\bin directory.

Usage

Run the following command on each WebSphere® Virtual Enterprise cell:
wsadmin -f manageWVEBB.py operation [nodeName serverName] 
You must 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 you 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 that are listed.
