Method Detail

clearApplicationRestartData

public void clearApplicationRestartData(ExecutionContext context)

Description copied from interface: RestartFunctions

Clears the information about previous application restart. Technically, it removes all records in the LSPS_APPL_RESTART_INFO table and sets the NUMBER_OF_MODEL_INSTANCES_TO_START in LSPS_VALUES to -1.

Specified by:

clearApplicationRestartData in interface RestartFunctions

watchStarting

public void watchStarting(ExecutionContext context,
                          RecordHolder modelInstance)

Description copied from interface: RestartFunctions

Adds the model instance to a list of started model instances. If the LSPS_APPL_RESTART_INFO table does not contain this model instance yet, it is being added. If the modelInstance parameter is is null the current model instance is used. Creating new record in the it sets ID, MODEL_INSTANCE, STATUS to IN_PROGRESS and START_DATE to the current time.

Specified by:

watchStarting in interface RestartFunctions

modelInstanceStartSucceeded

public void modelInstanceStartSucceeded(ExecutionContext context)

Description copied from interface: RestartFunctions

Tells that the model instance starting succeded. The FINISHED status is written to the LSPS_APPL_RESTART_INFO table on successful commit of the current GO-BOMN transaction unless an exception occurred.

Specified by:

modelInstanceStartSucceeded in interface RestartFunctions

explicitFinishing

public void explicitFinishing(ExecutionContext context)

Description copied from interface: RestartFunctions

Specifies that the current model instance starting is finished explicitly, by calling the modelInstanceStartSucceeded() function. If the current mode instance is in the LSPS_APPL_RESTART_INFO table and its status is IN_PROGRESS, this function changes the status to IN_PROGRESS_EXPLICIT_FINISH. If not, this function does nothing.

Specified by:

explicitFinishing in interface RestartFunctions

setCountOfModelInstancesToStart

public void setCountOfModelInstancesToStart(ExecutionContext context,
                                            Decimal count)

Description copied from interface: RestartFunctions

Sets the number of model instances to be restarted. It can be set in advance of the actual model instance restarting. Technically, it writes the number to the LSPS_VALUES table under the COUNT_OF_MODEL_INSTANCES_TO_START key.

Specified by:

setCountOfModelInstancesToStart in interface RestartFunctions

getStartStatus

public EnumerationImpl getStartStatus(ExecutionContext context,
                                      RecordHolder modelInstance)
                               throws ErrorException

Description copied from interface: RestartFunctions

Return start status for given model instance

Specified by:

getStartStatus in interface RestartFunctions

Returns:

starting status

Throws:

ErrorException

getStartStatuses

public MapHolder getStartStatuses(ExecutionContext context,
                                  SetHolder modelInstances)
                           throws ErrorException

Description copied from interface: RestartFunctions

Return start statuses for given model instances

Specified by:

getStartStatuses in interface RestartFunctions

Returns:

starting statuses

Throws:

ErrorException
