Enable the full-text search

The full-text search for objects in the Alfabet database and the full text search on top of the Help window require a search index to be available.

Configure the Alfabet Web Application to accept images from the help server.

For the full-text search of the online help, images in the search results are taken over directly from the Help web site. If you are implementing the full-text search for the online help, you need to add the root of the web server as allowed image source in the content security policy of the Alfabet Web Application:

1. Go to the Config subfolder of the physical directory of the Alfabet Web Application. By default, the physical directory is the AlfabetWebApplication sub-directory of the Alfabet installation directory.
2. Open the alfasettings.json file in a text editor.
3. Add the help server URL to the img-src specification in the ContentSecurityPolicyValue field of the AlfabetWebConfig JSON object. If the img-src is not yet defined, it needs to be added to the field:
   • img-src 'self' https://documentation.alfabet.com data:;
   • 'ContentSecurityPolicyValue': 'img-src 'self' https://documentation.alfabet.com data:; script-src 'self' 'nonce-{nonce}'; style-src 'self' 'nonce-{nonce}'; style-src-attr 'self' 'unsafe-inline'; object-src 'none'; frame-ancestors 'self'; frame-src 'self''

Specify a search index directory

• On the local file system, create a directory that shall include the search indices. The Alfabet components must have ReadWrite access to the directory.

  Schedule tab:

  • Schedule Time: Enter the start time for the job execution into the Start Time field.
  • Recurrence Pattern: Select one of the following check boxes and provide additional data, if applicable:
    • Hourly: The interval between job executions is the time selected in the field of every.
    • Daily: The interval between job executions is the number of days specified in the field day(s) as an integer.
    • Weekly: The interval between job executions is the number of weeks specified in the field week(s) on as an integer. In addition, select the checkbox of the day of the week that the job shall be executed for each recurrence.

For the definition of the end of the recurrence period, either select End after: and define the maximum number of occurrences in the Occurrences field or select End by: and select the end date for the job scheduling from the calendar in the field next to the checkbox entry. If you have selected Once in the Recurrence Pattern field, only define the date of execution via the Start Date field.

  Execution Info tab:

  This tab provides the ability to adapt the job scheduling to environmental conditions, like for example the scheduling of other jobs or maintenance windows during which execution shall be postponed.

  • Maximum Wait Time [min]: Enter a maximum time in minutes that the job execution can be postponed if one of the following applies:
    • The execution of jobs for the current job schedule depends on the execution of one or multiple other jobs to be finished because the execution result of one job is required to be available to execute this job or because both jobs perform conflicting actions. If a job of the current schedule shall be executed while a job defined in the Dependent Jobs field is still running, the job will not be executed but re-scheduled for execution five minutes later until the dependent jobs are finished.
    • A job for the current job schedule cannot be executed because the current execution time lies within a maintenance window. Maintenance windows are time periods that are blocked to avoid interruption of the job by maintenance work. If a job is due within a maintenance window period, the job will not be executed immediately. If the maintenance window is configured to re-schedule jobs, it will be re-scheduled for execution one minute after the end of the maintenance window. If the maintenance window is configured to skip jobs, the job execution during the maintenance window will be skipped and the next execution of the job is scheduled according to the settings in the Schedule tab of the job schedule editor.

      Maintenance windows must have been configured for the Alfabet components in order to adapt job scheduling to the maintenance window via the Maximum Wait Time [min] setting. For information about the definition of maintenance windows, see Update maintenance windows for the Job Schedule functionality.

    If the time between the originally due job execution and the end of the maintenance window or the end of execution of a dependent job exceeds the maximum wait time, job execution will be cancelled and an error message is written into the log file. The next execution of the job is scheduled according to the settings in the Schedule tab of the job schedule editor.

  •  Dependent Jobs: If the execution of jobs for the current job schedule shall be postponed if another job is still running, click New > Create New Job Dependency. Select the job schedule the current job schedule depends on in the list and click OK. If a job is running for one of the dependent job schedules, the execution of the job for the current job schedule will be shifted to the scheduled time plus minutes until the execution of all dependent jobs is finished. If the maximum wait time defined with Maximum Wait Time [min] is exceeded while dependent jobs are still running, the execution of the current job is cancelled and the next execution scheduled according to the settings in the Schedule tab of the job schedule editor.
  •  Expected Execution Time [min]: If a maximum time for execution of the job is defined in minutes in this field, a warning is written into the log file available via the Show Log button if the execution of a job for the current schedule exceeds the maximum wait time. The job is nevertheless further executed.
  •  Executing User: Select a user for which the wakeup events of the job schedule shall be executed. If no user is specified, the user editing the job schedule will be the execution user for the job schedule. Each time a scheduled job has been executed, the executing user will see a slide-in Event Feedback message window informing him/her whether the current execution was successful. If a result is available for download, a download link is displayed. By default, the slide-in message will be displayed to the user that created the job schedule when he/she is logged in with the same user profile as on creation of the job schedule. This default behavior can be changed. Select a user from the drop-down list to show the Event Feedback message to that user instead. Please note that the selected user must be logged in with the user profile defined in the Executing User Profile attribute to receive the Event Feedback messages for this job schedule.
  •  Executing User Profile: The user profile that the user defined with the Executing User attribute must be logged in with to receive Event Feedback messages for execution of this job schedule. By default, message will be displayed to the user that created the job schedule when he/she is logged in with the same user profile as on creation of the job schedule. This attribute is mandatory if Executing User is defined.
  • On Completion Jobs: You can configure jobs to be started after execution of the current job. This required configuration in both jobs.
    • Configure the indirectly triggered job without an own job schedule. In the Basic Data tab of this job, select the Indirectly Triggered checkbox.
    • Click the New button above the On Completion Jobs table of the current job and select Add. Select the job that shall be started on completion of the current job.
