Server Tasks

Autodesk uses several background processes to perform common housekeeping chores to ensure that the system runs optimally. The administrator has the ability to view which background processes are running on the server and how often they run by accessing the View Server Tasks dialog.

The Server Tasks dialog contains the following information:

• A status icon Indicates whether the task is active or inactive but scheduled to run again
• Server Task The name of the server task.
• Start/Scheduled The time at which the server task began or is scheduled to begin.
• Site The name of the site associated with the server task.
• Vault The name of the vault associated with the server task.
• Period The type of frequency with which the server task is executed. For example, a server task could be recurring or executed only on-demand.
• Frequency (minutes)-The number of minutes before the next execution of the process.

Background Processes

Task	Description
File Store Validation	Compares database metadata against the file store to determine if all of the files in the database exist in the file store.
File Store Replication Note: Vault Professional Only	Copies files that exist on one site's file store to another site's file store where the specific files do not exist. This process is scheduled by the user.
File Store Cleanup	The file store cleanup process removes files from the file store that have been deleted from the data management environment. This process is also known as the Vacuum Cleanup.
Update Statistics	Runs Update Statistics on the SQL database. This process improves query performance, which in turn improves vault performance.
ERP Packaging Note: Vault Professional Only	Communicates with an existing ERP system. ERP Integration must be enabled.
Property Re-indexing	Extracts properties from a bulk of files and updates the database with the new information. This operation can be started and stopped by the user. If the operation is stopped and restarted later, it will start with the last file processed.
Search Indexing	Takes properties from the database into the indexer for the first time. This indexing yields faster results when the user searches the database on specific properties.
Content Indexing Service	Extracts the full text contents from existing files in the vault, allowing full content searching. This process only runs if full-content searching is enabled. If full-content searching is enabled and you attach a vault, this process will initiate. If anything interrupts this process, it will continue from where it left once it is restarted.
Search Index Optimization	Updates the indexing engine which helps return search results quickly. When the process is running, the indexer is locked. This process runs during off hours to prevent user down time. If this process does not run, the vault server would have to index on demand, which would cause slower performance during peak use times.
Content Indexing Service Update	Adds newly created and updated content to the vault server's search index. This process runs every twenty minutes once full content searching is enabled.
Item Lock Cleanup Note: Vault Professional Only	When the vault server and the SQL server perform different actions on the database, it will apply locks to prevent data collision. If something interrupts these processes, these locks may never be removed. The item lock cleanup process runs through the database and removes any lock that is left behind. To change the time of the item lock index process, you need to edit the Web.config file. You can locate the Web.config file at C:\Program Files \Autodesk\ADMS Professional <year>\Server\Web\Services\Web.config. Look for this line and change the value to the time that you desire. <!--time of day to clear entity locks. --> <addkey="LockVacuumTime"value="3:0:0"/>
Delete Object Cleanup	Performs system maintenance by removing orphaned rows in the database.
Calculate Property Compliance	Makes sure files are meeting property policies and equivalence evaluations.
Object Change Notifications	Makes sure internal server data is kept in-sync when objects are changed by user or system actions.
