List running applications on running servers using wsadmin.sh

Use wsadmin and scripting to list all the running applications on all the running servers.

Before starting this task, wsadmin must be running. See the topic about starting the wsadmin scripting client using wsadmin.sh for more information. Use the following example to list all the running applications on all the running servers on each node of each cell.

• Jacl:

  *Provide this example as a Jacl script file and run it with  the "-f" option:
  1  #----------------------------------------------------------------
  2  # lines 4 and 5 find all the cell and process them one at a time 3  #----------------------------------------------------------------

  8     # process them at a time 9     #-----------------------------------------------------------------------
  10    set nodes [$AdminConfig list Node $cell]
  11    foreach node $nodes {
  12       #--------------------------------------------------------------
  13       # lines 16-20 find all the running servers belonging to the cell 
  14       # and node, and process them one at a time 15       #--------------------------------------------------------------

• Using Jython:

  * Provide this example as a Jython script file and run it with the "-f" option:
