Example: Using scripting to create and configure schedulers

Use wsadmin.sh 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"
