Method Detail

isRunning

public boolean isRunning(MonitorJobWaitForParams params)
                  throws ZosmfRequestException

Determines if a given job is in a running state or not.

Parameters:

params - monitor jobs params, see MonitorJobWaitForParams

Returns:

true if in running state

Throws:

ZosmfRequestException - request error state

waitByMessage

public boolean waitByMessage(Job job,

                      throws ZosmfRequestException

Given a Job document (has jobname/jobid), wait for the given message from the job. This API will poll for the given message once every 3 seconds for at least 1000 times. If the polling interval/duration is NOT sufficient, use "waitForMessageCommon" method to adjust.

See JavaDoc for "waitForMessageCommon" for full details on polling and other logic.

Parameters:

job - document of the z/OS job to wait for (see z/OSMF Jobs APIs for details)

message - message string

Returns:

job document

Throws:

ZosmfRequestException - request error state

waitByMessage

public boolean waitByMessage(String jobName,
                             String jobId,
                             String message)
                      throws ZosmfRequestException

Given the jobname/jobid, wait for the given message from the job. This API will poll for the given message once every 3 seconds for at least 1000 times. If the polling interval/duration is NOT sufficient, use "waitForMessageCommon" method to adjust.

See JavaDoc for "waitForMessageCommon" for full details on polling and other logic.

Parameters:

jobName - the z/OS jobname of the job to wait for output status (see z/OSMF Jobs APIs for details)

waitByOutputStatus

public Job waitByOutputStatus(Job job)
                       throws ZosmfRequestException

Given a Job document (has jobname/jobid), wait for the status of the job to be "OUTPUT". This API will poll for the OUTPUT status once every 3 seconds indefinitely. If the polling interval/duration is NOT sufficient, use "waitForStatusCommon" to adjust.

Returns:

job document

Throws:

ZosmfRequestException - request error state

waitMessageCommon

public boolean waitMessageCommon(MonitorJobWaitForParams params,
                                 String message)
                          throws ZosmfRequestException

Given jobname/jobid, check for the desired message continuously (based on the interval and attempts specified).

Parameters:

params - monitor jobs parameters, see MonitorJobWaitForParams object

message - message string

Returns:

job document

Throws:

ZosmfRequestException - request error state

waitStatusCommon

public Job waitStatusCommon(MonitorJobWaitForParams params)
                     throws ZosmfRequestException

Given jobname/jobid, check for the desired "status" (default is "OUTPUT") continuously (based on the interval and attempts specified).

The "order" of natural job status is: INPUT ACTIVE OUTPUT. If the requested status is earlier in the sequence than the current status of the job, then the method returns immediately (since the job will never enter the requested status) with the current status of the job.

Parameters:

params - monitor jobs parameters, see MonitorJobWaitForParams object

Returns:

job document

Throws:

ZosmfRequestException - request error state
