Description
Default distributed workmanager policy setting is WATERMARK. When the policy is not explicitly set to WATERMARK, setting up policy options for it won't persist the options and these will disappear after server reload. XML config does not contain the policy element or the policy-options.
When policy is explicitly set up (via a CLI command for example), the policy options will persist. XML config shows the policy element and policy-options.
Example:
Set up DWM, don't explicitly specify policy
batch
/subsystem=jca/distributed-workmanager=newdwm:add(name=newdwm)
/subsystem=jca/distributed-workmanager=newdwm/short-running-threads=newdwm:add(queue-length=10,max-threads=10)
/subsystem=jca/bootstrap-context=customContext1:add(name=customContext1,workmanager=newdwm)
run-batch
reload
Check the config, we're using WATERMARK
/subsystem=jca/distributed-workmanager=newdwm:read-resource
{
"outcome" => "success",
"result" => {
"elytron-enabled" => false,
"name" => "newdwm",
"policy" => "WATERMARK",
"policy-options" => undefined,
"selector" => "PING_TIME",
"selector-options" => undefined,
"long-running-threads" => undefined,
"short-running-threads" => {"newdwm" => undefined},
"statistics" => {
"local" => undefined,
"distributed" => undefined
}
}
}
Set up the policy option
/subsystem=jca/distributed-workmanager=newdwm:write-attribute(name=policy-options,value={watermark=1})
Read the config again, everything looks OK
/subsystem=jca/distributed-workmanager=newdwm:read-resource
{
"outcome" => "success",
"result" => {
"elytron-enabled" => false,
"name" => "newdwm",
"policy" => "WATERMARK",
"policy-options" => {"watermark" => "1"},
"selector" => "PING_TIME",
"selector-options" => undefined,
"long-running-threads" => undefined,
"short-running-threads" => {"newdwm" => undefined},
"statistics" => {
"local" => undefined,
"distributed" => undefined
}
}
}
Reload and read the config yet again, policy option is gone
reload
/subsystem=jca/distributed-workmanager=newdwm:read-resource
{
"outcome" => "success",
"result" => {
"elytron-enabled" => false,
"name" => "newdwm",
"policy" => "WATERMARK",
"policy-options" => undefined,
"selector" => "PING_TIME",
"selector-options" => undefined,
"long-running-threads" => undefined,
"short-running-threads" => {"newdwm" => undefined},
"statistics" => {
"local" => undefined,
"distributed" => undefined
}
}
}
