Crontab Import

Standard jobs and run-parts jobs (on Linux only) scheduled in cron tables can be imported into the Dollar Universe Tasks and Uprocs (on the selected node). Dollar Universe not only supplements the scheduling functions offered by cron, but also enables production to be monitored across many machines.

The run-parts jobs (on Linux only) are displayed by user entry in the wizard (step 1). For example, if root is the run part user: "root (run part)". These jobs are not selected by default. Selected scripts are moved to the Uproc directory (they are added to the Uproc’s files). The run-part command in the /etc/crontab file is never displayed in the Wizard and the line is never disabled (commented).

To import cron jobs, Dollar Universe IO server must be run by root or a user with administrator rights (installation by an administrator is not enough). If the IO server is not run by an administrator, the Crontab can't be imported.

Task Selection

The displayed list shows the cron tables sorted by user.

• To reduce a user cron table, click the – near the user name.
• To expand a user cron table, click the + near the user name.
• The comments, blank lines in the cron tables may not appear in this list. Refer to section "Cron Import".

The cron wizard will display no job for a run-part job if there is no script in the directory targeted by the run-parts utility.

Statuses:

• Not imported: the user can select the job to be imported into Dollar Universe.
• Already imported: the job has already been imported into Dollar Universe. It is commented out in the cron table.
• Disabled: the user has disabled the cron job.
• Not importable: not recognized as a cron job (syntax problem, comment line…)

In the User column, check one or more boxes to select cron jobs to be imported (use the Select All or Unselect All buttons).

Click Next at the bottom of the window. Double-click on the title bar if the buttons are not visible.

Task List Preview

This window lists all the cron jobs selected in the previous window.

At this point, the jobs have not yet been created in Dollar Universe nor commented in the cron tables.

Cron Task List Preview – Toolbar:

• View variables: displays variables extracted from the cron tables and from the user environments. These variables will be transported to the task MU during its creation.

User: user defined variables

Generic: system variables needed by Dollar Universe to run the job

• Update: select a line and click Update. Univiewer opens the job definition:

From a Uproc (if chosen): Refer to section "Uproc Details".

From a Task: (if chosen): Refer to section "Task Details".

The next name is automatically attributed to the Task MU: <SUBMISSION ACCOUNT>_<DUAS NODE NAME>.

• Select All/Unselect All: select or unselect all jobs in the list.
• Rename: rename all the selected Tasks (box checked) using the Name pattern value. By default the name of an imported job is: !CONVINDEX!– !CMD!

!XX!: means that XX is a specific Dollar Universe variable

CONVINDEX: is an index, automatically incremented during the job conversion

CMD: is the job command line

To modify the Task name:

• Select the Task from the list (check its box).
• Enter its new name in the Name pattern field or

Information Window

For more information on cron security, refer to the UNIX system documentation.

• The Nodes tab in the Information window displays the Dollar Universe Server Node status.

Principles of cron Security: crontab can be run if the user’s name appears in the file /usr/lib/cron/cron.allow.

• If that file does not exist, crontab can be used if the user’s name does not appear in the file /usr/lib/cron/cron.deny.
• If only cron.deny exists and is empty, all users can use crontab.
• If neither file exists, only the root user can use crontab. The allow/deny files consist of one user name per line."

In other words, for each user: (Y=allowed, N=forbidden):

The following messages are displayed in the "Tips" zone:

Local Admin UVMS Users (this type of user has administrative rights on UVMS):

Regular UVMS users (this type of user has restricted access to the administration mode of UVC):
