ADMIN_TASK_STATUS administrative view - Retrieve task status information

The ADMIN_TASK_STATUS administrative view retrieves information about the status of task execution in the administrative task scheduler.

The schema is SYSTOOLS.

This view is created the first time the ADMIN_TASK_ADD procedure is called.

Authorization

SELECT or CONTROL privilege on the ADMIN_TASK_STATUS administrative view. Unless the database was created with the RESTRICTIVE option, SELECT privilege is granted to PUBLIC by default.

When you query the ADMIN_TASK_STATUS view, it will only return the task status records that were created by your session authorization ID.

Default PUBLIC privilege

In a non-restrictive database, SELECT privilege is granted to PUBLIC when the view is automatically created.

Examples

Example 1: Request the status of tasks in the scheduler:

SELECT * from SYSTOOLS.ADMIN_TASK_STATUS

Example 2: Format the data in the SQLERRMC column using the SQLERRM function:

SELECT TASKID, STATUS, SQLCODE, SQLSTATE, RC,
   VARCHAR( SQLERRM( 'SQL' || CHAR( ABS(SQLCODE) ),
   SQLERRMC, x'FF', 'en_US', 1 ), 256) AS MSG_TXT
   FROM SYSTOOLS.ADMIN_TASK_STATUS

Information returned

Table 1. Information returned by the ADMIN_TASK_STATUS administrative view
Column name	Data type	Description
NAME	VARCHAR(128)	The name of the task.
TASKID	INTEGER	The task identifier.
STATUS	VARCHAR(10)	The status of the task. Valid values are: `RUNNING` - The task is currently running. `COMPLETED` - The task has finished running. `NOTRUN` - An error prevented the scheduler from calling the task's procedure. `UNKNOWN` - The task started running but an unexpected condition prevented the scheduler from recording the task outcome. This can occur if the system ends abnormally or a power failure happens while the task is running.
INVOCATION	INTEGER	The current invocation count.
BEGIN_TIME	TIMESTAMP	The time that the task began.¹ If the STATUS is `RUNNING`, `COMPLETED`, or `UNKNOWN`, this value indicates the time that the task started running. If the STATUS is `NOTRUN`, it indicates the time that the task should have started.
END_TIME	TIMESTAMP	The time that the task finished running.¹ This value will be `NULL` if the STATUS is `RUNNING`. If the STATUS is `UNKNOWN`, this value is the time the task scheduler detected the task was no longer executing and updated the status table.
AGENT_ID	BIGINT	agent_id - Application handle (agent ID) monitor element
SQLCODE	INTEGER	If the STATUS is `COMPLETED`, this value indicates the SQLCODE returned by the CALL to the procedure. If the STATUS is `NOTRUN`, this value indicates the SQLCODE of the error that prevented the task from running. If the status is `RUNNING` or `UNKNOWN`, this value will be `NULL`.
SQLSTATE	CHAR(5)	If the STATUS is `COMPLETED`, this value indicates the SQLSTATE returned by the CALL to the procedure. If the STATUS is `NOTRUN`, this value indicates the SQLSTATE of the error that prevented the task from running. If the status is `RUNNING` or `UNKNOWN`, this value will be `NULL`.
SQLERRMC	VARCHAR(70) FOR BIT DATA	Contains one or more tokens, separated by X'FF', as they appear in the SQLERRMC field of the SQLCA. These tokens are substituted for variables in the descriptions of error conditions If the STATUS is `COMPLETED`, this value indicates the SQLERRMC returned by the CALL to the procedure. If the STATUS is `NOTRUN`, this value indicates the SQLERRMC of the error that prevented the task from running. If the status is `RUNNING` or `UNKNOWN`, this value will be `NULL`.
RC	INTEGER	If the STATUS is `COMPLETED`, this contains the return code from the CALL to the procedure if the procedure had a return code. Otherwise, this will be `NULL`.

¹ The BEGIN_TIME and END_TIME are based on the database server's time zone. The user is responsible for making adjustments for daylight savings time (DST).
