Understanding system tasks

System tasks take care of scheduling tasks not related to search sources. There are far fewer system tasks than search data source tasks.

Only administrators with accounts that include the PRIV_TASK_MANAGE privilege can access, schedule, and launch tasks.

You can execute these system tasks:

System Task

Description

SD_ASSET_EXTRACTOR

Harvests metadata, document text, and text scanned from graphics in the asset repository.

The metadata is harvested from documents in the repository and from metadata entered when adding or editing an asset (see Adding a digital asset and Modifying the details of a digital asset).

Portfolio indexes text from the following types of files:

•

*.pdf

•

*.txt, *.rtf (plain text, rich text)

•

*.doc, *.docx (Microsoft Word)

•

*.xls, *.xlsx (Microsoft Excel)

Portfolio uses optical character recognition (OCR) scanning to index text in the following image file types:

•

*.jpg

•

*.gif

•

*.tiff

•

*.png

•

*.bmp

Note: For the best OCR scan results, text in images should be straight, clear, and not include graphics or background images.

After Portfolio runs the task, it then runs SD_ASSET_IMPORT, and the SD_ASSET_INDEX. You can schedule how frequently Portfolio runs this process or you can choose to run manually it as needed. (For more information about digital assets, see Managing digital assets.)

SUGGEST_TERM_JOB

Updates the search suggestions list, if search suggestions are enabled for search profiles. You can schedule how frequently Portfolio runs this process. Because of the amount of memory needed for this task, SirsiDynix suggests that you schedule it to run after midnight and not concurrent with any of the ILS tasks. (For more information about search suggestions, see Managing search suggestions.)

SD_CONTENT_EXTRACTOR

Harvests content from the rooms in your system, including any SirsiDynix authored content. After Portfolio runs this task, it then runs the SD_CONTENT_IMPORT and SD_CONTENT_INDEX processes in succession. You can schedule how frequently Portfolio runs this process, however, it may be most effective to run the SD_CONTENT_EXTRACTOR as needed. (For more information, see Creating and editing room content.)
