Do not change the files that are used by a task.

The following describes the name and details of each task:

• Data maintenance
  To maintain data integrity between the managing server database and the Asset Information Manager Subset database, this task updates related information according to the updated information. This task also deletes unneeded information.
  Make sure that you enable this task after you have finished setting up Asset Information Manager Subset.
  For details about how to specify the tasks to be executed in Data maintenance, see 10.7.2 Specifying the work to be performed by the Data maintenance task.
  
• Delete change log
  Deletes all the asset information logs and change logs except for the information for a specified period.
  In the default setting, the Delete change log task deletes the history information of asset information that is more than six months old at 6:30 a.m. on the first day of every month. For details about the procedure for changing the date and time and the frequency of task execution, see 10.7.3 Specifying the types of history information to be deleted and the deletion timing.
  
• Take inventory
  Imports inventory information into the Asset Information Manager Subset database. When you acquire updated inventory information in real time, there is no need to use this task.
  For the procedure for specifying an option to re-acquire all inventory information, see 10.7.4 Acquiring all inventory information.
  For details about the inventory information that can be acquired, see 10.9 Inventory information that can be displayed by Asset Information Manager Subset.
  
• Acquiring directory information
  Imports group and user information into the Asset Information Manager Subset database from the directory information. It is recommended that you execute this task after directory information has been updated.
  You should not acquire directory information together with user inventory information because the group and user information may be duplicated.
  For details about how to acquire directory information, see 10.7.6 Acquiring directory information.
  

  Note

  When you acquire directory information, you cannot select whether or not the existing data is to be overwritten. The assigned group or user names will be overwritten by the corresponding directory information.
