Purpose

This program is a tool of the search engine service. It is to be used for system administration and can be executed in the dialog or in the background.

You can use this program to delete change pointers.

Integration

For business objects that use the search engine service, a change pointer is generated every time an object is changed. The change pointers in the search engine service therefore represent events. They are the basis for delta indexing. For more information about delta indexing, see the documentation of the indexing program COM_SE_DISPATCHER.

During delta indexing, the evaluated change pointers are not deleted immediately. Instead, their status is changed from 1 = Initial to 2 = Processed. This means that they can be reactivated if required. For more information, see the documentation of the program COM_SE_CPOINTER_REACTIVATE.

The most important reason for the reactivation of change pointers is the reconstruction of the search engine indexes based on a data backup of the search engine. The change pointers of the search engine service can therefore be deleted as soon as their time stamp is after a data backup of the search engine.

Prerequisites

None.

Features

This program only deletes entries in the database table COM_SE_CPOINTER in which the change pointers are stored. The program does not communicate with the search engine or the application from which the business objects in question have come.

The selected change pointers are deleted no matter what their processing status.

Selection

Specify the date up to which the change pointers are to be deleted. The date is interpreted by the system in accordance with UTC. It corresponds to the time zone "Greenwich Mean Time" (GMT).

For safety reasons, the default value on the selection screen is the last day of the year before last.

If required, you can restrict the program run to a business object and an object type contained in this business object.

Standard Variants

Output

You receive a confirmation of your selection and the number of change pointers deleted.

Activities

Example

If you backup the data in your search engine once a week, you can delete the change pointers of the search engine service up to the beginning of the previous month with a monthly background job.##################################################################
