Display all Hide all

Use this function to list and track the tasks (requests) sent to the batch server, either from a request submission or request files placed in a dedicated directory. 

You can use it to relaunch and stop tasks, and for starting recurring batch tasks.

You can check the status of the batch server. Each task executed by the batch server is assigned an individual process ID.

Presentation

Each line in the Query results grid (table) is a task submitted to the batch server (released or not released). Each task has a status and is displayed using a color. The color reflects the status of the task. The standard colors are as follows:

  • Green. Task currently being executed.
  • Black. Task finished without error.
  • Red. Task interrupted or terminated with errors.
  • Blue. Task pending execution.

The following fields are present on this tab :

Grid Queries

  • Number (field NUMREQ)

This number identifies this task (request). It is a sequential number assigned automatically from an initial number defined in the batch server parameters.

This field defines the folder in which execution of this task was requested.

This code identifies the launched task.

Defines the language in which this task is expressed.

This field defines the code of the user who launched this task.
  • Date (field DAT)

This field defines the planned start date for this task.
  • Time (field HEURE)

This field defines the planned start time (on the defined date) for this task.
  • Single (field MONO)

This field is set to 'Yes' or 'No'. If set to 'Yes', this task can only be executed in single user mode for the folder.
  • Status (field FLAG)

This field displays the current status of the task in process. The values are defined in Local menu 21 - Query progress status, as follows:

  • Standby. This task has not yet started.
  • In progress. This task is currently being executed.

  • Warning. This task finished on a non-blocking error code (GERRBATCH variable<100).
  • End time (field HFIN)

This field defines the time of execution of this task (on the defined date). This field is only displayed if this task has been launched and execution is complete.
  • End date (field DFIN)

This field defines the date of execution of this task. This field is only displayed if this task has been launched and execution is complete.
  • Task type (field TYPTAC)

This field is defined by Local menu 20 - Batch Task Type. It defines whether this task has been launched as a process or a script (shellscript or command file) executed on the batch server.

This field displays the code of a process or a script if this (launched) task does not correspond to a basic function.
  • Server (field SERVER)

This field displays the number of the server assigned to this task.
  • Port (field PORT)

This field displays the (port) number of this task on the defined server.

Each task (request) is executed by a process on the application server. This field identifies the process number (this is usually called the process ID or PID) for this task.
  • Time-out (field TIMOUT)

This field, if populated, defines a timeout duration, that is, a time limit above which this task will be stopped automatically if it is still running.

This field is populated if this task belongs to a (launched) group of tasks. The code, if displayed, is common to all tasks in the group.
  • Order no. (field NUMGRP)

This field is populated if this task belongs to a (launched) group of tasks. The number, if displayed, is common to all tasks in the group.
  • Sequence (field SEQGRP)

This field is populated if this task belongs to a (launched) group of tasks. The number, if displayed, represents the sequence number of this task in the group.
  • Frequency (min) (field FRQ)

When the batch task is launched at a specified frequency every N minutes, this column defines the value of N.
  • Reminder (field IMPETX)

This field is populated if this task has been subscribed to be executed with a frequency. Each time this task is relaunched this column is incremented by 1. The number displayed represents the number of times this task has been executed.
  • Batch file (field JOB)

This field is populated if this task has been launched using a job file (see the corresponding technical appendix). It displays the name of the submitted file (without the extension).

If this field is selected (ticked), a file containing the defined parameters for this query will be generated in the template file directory (batch server parameters) and the query will not be submitted to the server. The file name is the task code suffixed with '.mod'. The file becomes a template that can be used to create the .job files that permit creation of the batch requests.

Close

Click the Query action to submit a new task request.

Click the Update action to refresh the task list and corresponding statuses. Alternatively, use the Refresh (F5) key.

Click the Log action to display the general trace file for the server (start time, request launch, end of request). The trace file is called server.tra. It can be found in the TRA directory of the SERVX3 directory (which is located in the Runtime directory).
