Configure processes using scripting

 

Procedure

1. Start wsadmin

2. Identify the server and assign it to the s1 variable. For example:

   • Jacl:

     set s1 [$AdminConfig getid /Cell:mycell/Node:mynode/Server:server1/]
     

   • Jython

     s1 = AdminConfig.getid('/Cell:mycell/Node:mynode/Server:server1/')
     print s1
     

   where:

   set	is a Jacl command
   s1	is a variable name
   $	is a Jacl operator for substituting a variable name with its value
   AdminConfig	is an object representing the WAS configuration
   getid	is an AdminConfig command
   Cell	is the object type
   mycell	is the name of the object that will be modified
   Node	is the object type
   mynode	is the name of the object that will be modified
   Server	is the object type
   server1	is the name of the object that will be modified
   print	a Jython command

   Example output:

   server1(cells/mycell/nodes/mynode/servers/server1|server.xml#Server_1)
   

3. Identify the process definition belonging to this server and assign it to the processDef variable. For example:

   • Jacl:

     set processDef [$AdminConfig list JavaProcessDef $s1]
     set processDef [$AdminConfig showAttribute $s1 processDefinition]
     

   • Jython:

     processDef = AdminConfig.list('JavaProcessDef', s1)
     print processDef
     processDef = AdminConfig.showAttribute(s1, 'processDefinition')
     
     

   Example output:

   (cells/mycell/nodes/mynode/servers/server1|server.xml#JavaProcessDef_1)
   

4. Change the attributes.

   • On distributed systems, the following example changes the working directory.

     • Jacl:

       $AdminConfig modify $processDef {{workingDirectory c:/temp/user1}}
       

     • Jython:

       AdminConfig.modify(processDef, [['workingDirectory', 'c:/temp/user1']])
       

   • The following example modifies the stderr file name:

     • Jacl:

       set errFile [list stderrFilename \${LOG_ROOT}/server1/new_stderr.log]
       set attr [list $errFile]
       $AdminConfig modify $processDef [subst {{ioRedirect {$attr}}}]
       

     • Jython:

       errFile = ['stderrFilename', '\${LOG_ROOT}/server1/new_stderr.log']
       attr = [errFile]
       AdminConfig.modify(processDef, [['ioRedirect', [attr]]])
       

   • The following example modifies the process priority:

     • Jacl:

       $AdminConfig modify $processDef {{execution {{processPriority 15}}}}
       

     • Jython:

       AdminConfig.modify(processDef, [['execution', [['processPriority', 15]]]])
       

   • The following example changes the maximum startup attempts. We can modify this example to change other attributes in the process definition object.

     • Jacl:

       $AdminConfig modify $processDef {{monitoringPolicy {{maximumStartupAttempts 1}}}}
       $AdminConfig save
       

     • Jython:

       AdminConfig.modify(processDef, [['monitoringPolicy', [['maximumStartupAttempts',  1]]]])
       

5. In a network deployment environment only, synchronize the node.
