Class ScheduleSpec

java.lang.Object
  com.novell.zos.jdl.ScheduleSpec

public class ScheduleSpec
extends java.lang.Object

The ScheduleSpec class defines one or more Joblets to be scheduled and run on resources. A ScheduleSpec instance is passed to the Job's schedule(). schedule() creates the Joblets and schedules Joblets to run on resources.

Example of using a ScheduleSpec to schedule a single Joblet:

      s = ScheduleSpec()
      s.setJobletClass(MyJoblet)
      self.schedule(s)
 

This class is only allowed in the Job class.

Field Summary

static int	ACTIVE_NODE_SET Used to specify that the joblet set will be constructed after applying resource constraints to the set of active/online resource.
static int	PROVISIONABLE_NODE_SET Used to specify that the joblet set will be constructed after applying resource constraints to the set of provisionable resource.

Constructor Summary

ScheduleSpec()
Construct a ScheduleSpec with defaults.

Method Summary

int	getCount() Retrieve number of Joblets created for this set.
void	setConstraint(Constraint constraint) Assign a Constraint for resource selection.
void	setConstraint(java.lang.String constraint) Assign a Constraint in XML for resource selection.
void	setCount(int count) Assign the maximum number of Joblets to create for this set.
void	setJobletArgs(org.python.core.PyDictionary facts) Define facts for this jobletargs namespace for a Joblet.
void	setJobletClass(org.python.core.PyClass jobletClass) Assign the Joblet Class to use for Joblet execution on the resource.
void	setJobletFacts(org.python.core.PyDictionary facts) Define additional joblet facts for this ScheduleSpec.
void	setUseNodeSet(int nodeSet) If set to True, the joblet set will be constructed after applying resource constraints to the set of provisionable resource.

Field Detail

ACTIVE_NODE_SET

public static int ACTIVE_NODE_SET

Used to specify that the joblet set will be constructed after applying resource constraints to the set of active/online resource.

PROVISIONABLE_NODE_SET

public static int PROVISIONABLE_NODE_SET

Used to specify that the joblet set will be constructed after applying resource constraints to the set of provisionable resource.

Constructor Detail

ScheduleSpec

public ScheduleSpec()

Construct a ScheduleSpec with defaults.

Method Detail

setCount

public void setCount(int count)

Assign the maximum number of Joblets to create for this set. This value overrides the setMaxJobleSize in ParameterSpace.

Parameters:

count - Number of Joblets to create

getCount

public int getCount()

Retrieve number of Joblets created for this set. Only valid after scheduleSweep().

Returns:

Number of Joblets created

setJobletClass

public void setJobletClass(org.python.core.PyClass jobletClass)

Assign the Joblet Class to use for Joblet execution on the resource.

Parameters:

jobletClass - Reference to Joblet class to execute on node

setConstraint

public void setConstraint(Constraint constraint)

Assign a Constraint for resource selection. This additional Constraint is AND'd to any existing constraints including the aggregated Policies.

  constraint = EqConstraint()
  constraint.setFact("resource.os.name")
  constraint.setValue("Windows XP")

  ScheduleSpec = ScheduleSpec()
  ScheduleSpec.setJobletClass(MyJoblet)
  ScheduleSpec.setConstraint(constraint)
 

Parameters:

constraint - Constraint for resource selection

setConstraint

public void setConstraint(java.lang.String constraint)

Assign a Constraint in XML for resource selection. This additional Constraint is AND'd to any existing constraints including the aggregated Policies.

      ScheduleSpec = ScheduleSpec()
      ScheduleSpec.setJobletClass(MyJoblet)
      ScheduleSpec.setConstraint("")
 

Parameters:

constraint - Constraint as XML for resource selection

setUseNodeSet

public void setUseNodeSet(int nodeSet)

If set to True, the joblet set will be constructed after applying resource constraints to the set of provisionable resource. If false (the default) the active or online set of resources will be used instead.

Parameters:

nodeSet - true to reference provisionable set of nodes rather than active set.

setJobletArgs

public void setJobletArgs(org.python.core.PyDictionary facts)

Define facts for this jobletargs namespace for a Joblet. Each Joblet created for this schedulet gets a copy of this set of Joblet arguments facts.

Parameters:

facts - Dictionary of facts to add to each Joblet' factset

setJobletFacts

public void setJobletFacts(org.python.core.PyDictionary facts)

Define additional joblet facts for this ScheduleSpec. Each Joblet created for this set inherits the base set of Joblet facts and any facts supplied to this function.

Parameters:

facts - Dictionary of facts to add to each Joblet factset
