Example: Use scripting to create and configure schedulers

Use the wsadmin scripting tool to invoke a Jacl script and create a SchedulerConfiguration resource.

The following Jacl example script can be invoked using wsadmin.sh, which creates a SchedulerConfiguration resource using the DefaultWorkManager at the server scope.

# Example JACL Script to create a SchedulerConfiguration 
# at the server scope 
# Change the cell, node and server to match the environment set cellName   MyCell
set nodeName   MyNode
set serverName server1

# We can just grab the first provider, since there is only one at the # server scope level.
set schedProv [$AdminConfig getid /Cell:$cellName/Node:$nodeName/Server:$serverName/SchedulerProvider:SchedulerProvider]

if {$schedProv == ""} {
    puts "Unable to find SchedulerProvider for server: $serverName.  Aborting."
    exit
}
puts "Found a SchedulerProvider"

# Create a WorkManager for our scheduler at the server scope. 
# We could use any of the other scopes as long as it is at the same # or higher than the Scheduler's scope.
set wrkMgrProv [$AdminConfig getid /Cell:$cellName/Node:$nodeName/Server:$serverName/WorkManagerProvider:WorkManagerProvider/]

if {$wrkMgrProv == ""} {
    puts "Unable to find the WorkManagerProvider for server: $serverName.  Aborting."
    exit
}
puts "Found a WorkManagerProvider"

set wmName             "MyScheduler WorkManager"
set wmJNDIName         "wm/MySchedWorkManager"
set wmIsGrowable       false set wmMaxThreads       1
set wmMinThreads       0
set wmNumAlarmThreads  10
set wmServiceNames     "com.ibm.ws.i18n;security;UserWorkArea;zos.wlm"
set wmThreadPriority   5

# Setup our DefaultWorkManager attributes set createAttrs [subst { \
    {isGrowable $wmIsGrowable} \

    {name "$wmName"} \
    {numAlarmThreads $wmNumAlarmThreads} \

    {threadPriority $wmThreadPriority} }]

puts "Creating a WorkManager"
$AdminConfig create WorkManagerInfo $wrkMgrProv $createAttrs
puts "WorkManager Created"
