Task3000 Personal Server |
|
Basic job of the Task3000 Personal Server is to execute the
prepared tasks according to the parameters given and maintaining the Task Queue.
Main Task3000 Server/Task3000 Personal Server
benefits:
-
Managing the task queue,
task(s) can be controlled easily with insinuative menu system. Tasks can be
monitored in their execution queues (Ready, Running, Waiting and Complete),
with all general parameters and step parameters.
-
Very complex but easy to
use scheduler enables you to run tasks on appropriate date/time. Nonworking
days are easily excluded; repetitions of the tasks can be easily controlled
during long period of time and all that is controlled with just one menu on
Task3000 Workstation with several parameters. Task3000 server administrator
can change parameters during and before task execution.
-
Task3000 server
administrator can control dispatching priority and can thus influence on the
total server throughput.
-
Classes can be used to
set the initial execution limits automatically. Tasks can be grouped
depending on the importance and desired execution by classes automatically.
With classes we can also defined limits, under which task execution will be
terminated, because task uses too much computer resources (memory, CPU time
and on Windows 2000 or higher also input-output). After task consumes
defined resources, it is automatically cancelled. However, after task is
cancelled, server gives the task some time to enable the necessary cleaning
after abnormally ended task.
-
Each task gets it own
Task Number and automatically generated directory for storing the data
(%T3S% directory, actual structure is domain, user, project, task number).
Number of created directory for each task can be controlled on server level.
This enables easy handling of the multiple task execution.

Task3000 Personal Server only:
-
Task3000 Personal Server
run as application program in the context of current user. It is started
automatically when the user submits the task.
-
Only one task can be
executed simultaneously.
-
Task3000 Personal Server
does not maintain security on the file system.
-
Task3000 Personal Server
best usage is to design and test the tasks, which will be executed on the
dedicated Task3000 Server. Errors and strange behavior can be monitored
without the risk of the danger, that this will influence the normal Task3000
Server functioning.
-
Other usage is complex
execution of several programs; each program is executed in one step.
-
During
task execution user can control programs normally via GUI, but this
interactive behavior must be eliminated to run the task automatically on the
dedicated Task3000 Server.
Warning: On the Windows 98/ME execution of Task3000
Personal Server is limited:
-
Task step commands like
Cancel, Stop, Start are valid from next step only and do not influence the
current step execution. Stopping the current program execution is very
unstable on the Windows 98/ME by design.
-
Execution is subject to
very serial processing; every message box stops the execution of the all
tasks etc.
-
Capturing of the console
window automatically works well only for the console window with number of
lines 25 and 43. Use output redirection to files instead.
-
During executing
blinking of the console window is normal.
-
Command prompt must be
used like Command.com /c. Using of Command /c only produce strange results.
In
spite of all that, experienced developer can use Windows 98/ME to develop the
task, which will be executed on the Task3000 server with only minor or no
modifications.
