NAME
drmaa_job_ps, drmaa_control, - Monitor and control jobs

SYNOPSIS
#include "drmaa.h"

int drmaa_job_ps(
    const char *job_id,
    int *remote_ps,
    char *error_diagnosis,
    size_t error_diag_len
);

int drmaa_control(
    const char *jobid,
    int action,
    char *error_diagnosis,
    size_t error_diag_len
);

DESCRIPTION
The drmaa_job_ps() function returns the status of the xxQS_NAMExx job job_id into the integer pointed to by remote_ps. Possible return values are

    DRMAA_PS_UNDETERMINED        job status cannot be determined
    DRMAA_PS_QUEUED_ACTIVE       job is queued and active
    DRMAA_PS_SYSTEM_ON_HOLD      job is queued and in system hold
    DRMAA_PS_USER_ON_HOLD        job is queued and in user hold
    DRMAA_PS_USER_SYSTEM_ON_HOLD job is queued and in user and system hold
    DRMAA_PS_RUNNING             job is running
    DRMAA_PS_SYSTEM_SUSPENDED    job is system suspended
    DRMAA_PS_USER_SUSPENDED      job is user suspended
    DRMAA_PS_DONE                job finished normally
    DRMAA_PS_FAILED              job finished, but failed

Jobs' user hold and user suspend states can be controlled via For affecting system hold and system suspend states the appropriate xxQS_NAMExx interfaces must be used.

  drmaa_control()
The drmaa_control() function applies control operations on xxQS_NAMExx jobs. jobid may contain either an xxQS_NAMExx jobid or `DRMAA_JOB_IDS_SESSION_ALL' to refer to all jobs submitted during the DRMAA session opened using Legal values for action and their meanings are:

    DRMAA_CONTROL_SUSPEND        suspend the job
    DRMAA_CONTROL_RESUME         resume the job,
    DRMAA_CONTROL_HOLD           put the job on-hold
    DRMAA_CONTROL_RELEASE        release the hold on the job
    DRMAA_CONTROL_TERMINATE      kill the job

The DRMAA suspend/resume operations are equivalent to the use of `-s <jobid>' and `-us <jobid>' options with xxQS_NAMExx The DRMAA hold/release operations are equivalent to the use of xxQS_NAMExx and The DRMAA terminate operation is equivalent to the use of xxQS_NAMExx Only user hold and user suspend can be controlled via For affecting system hold and system suspend states the appropriate xxQS_NAMExx interfaces must be used.

ENVIRONMENTAL VARIABLES

xxQS_NAME_Sxx_ROOT
    Specifies the location of the xxQS_NAMExx standard configuration files.

xxQS_NAME_Sxx_CELL
    If set, specifies the default xxQS_NAMExx cell to be used. To address a xxQS_NAMExx cell xxQS_NAMExx uses (in the order of precedence):

        The name of the cell specified in the environment variable xxQS_NAME_Sxx_CELL, if it is set.

        The name of the default cell, i.e. default.

xxQS_NAME_Sxx_DEBUG_LEVEL
    If set, specifies that debug information should be written to stderr. In addition the level of detail in which debug information is generated is defined.

xxQS_NAME_Sxx_QMASTER_PORT
    If set, specifies the tcp port on which is expected to listen for communication requests. Most installations will use a services map entry instead to define that port.

RETURN VALUES
Upon successful completion, drmaa_job_ps(), and drmaa_control() return DRMAA_ERRNO_SUCCESS. Other values indicate an error. Up to error_diag_len characters of error related diagnosis information is then provided in the buffer, error_diagnosis.

ERRORS
The drmaa_job_ps(), and drmaa_control() will fail if:

  DRMAA_ERRNO_INTERNAL_ERROR
Unexpected or internal DRMAA error, like system call failure, etc.

  DRMAA_ERRNO_DRM_COMMUNICATION_FAILURE
Could not contact DRM system for this request.

  DRMAA_ERRNO_AUTH_FAILURE
The specified request was not processed successfully due to authorization failure.

  DRMAA_ERRNO_INVALID_ARGUMENT
The input value for an argument is invalid.

  DRMAA_ERRNO_NO_ACTIVE_SESSION
Failed because there is no active session.

  DRMAA_ERRNO_NO_MEMORY
Failed allocating memory.

  DRMAA_ERRNO_INVALID_JOB
The specified job does not exist.

The drmaa_control() will fail if:

  DRMAA_ERRNO_RESUME_INCONSISTENT_STATE
The job is not suspended. The resume request will not be processed.

  DRMAA_ERRNO_SUSPEND_INCONSISTENT_STATE
The job is not running and thus cannot be suspended.

  DRMAA_ERRNO_HOLD_INCONSISTENT_STATE
The job cannot be moved to a hold state.

  DRMAA_ERRNO_RELEASE_INCONSISTENT_STATE
The job is not in a hold state.
