Monitoring and Controlling Indexes 

Use

Transaction SES_ADMIN is the central transaction for administrating the search engine service. The user interface (admin UI) for this transaction contains all important information and functions directly. Functions that you use less often are available in the menu.

Prerequisite

You have the authorization to use the transaction SES_ADMIN. You need the following roles:

●      SAP_BC_SES_ADMIN

●      SAP_BC_SXES_ADMIN

Features

Index Monitor

The central element of the admin UI is the index monitor. It displays the current status of all indexes in a table. This provides an integrated view of information about the search engine service and the connected TREX system, in particular about the inbound processing (queue).

In each row, you can see the following information about an index:

●      Business object and object type

●      Information on whether it is an object index or a relations index

An object index contains the indexed business objects. A relations index contains the indexed relations that belong to the business objects.

●      Flag for whether the index is active

●      Start, end, and status of the last indexing

●      Number of objects in the last indexing

●      Queue: Number of objects in processing

●      Queue: Number of objects with an error status

●      Queue: Number of optimized objects (completely indexed)

For more information about the meaning of the columns, see the F1 help.

You can choose Change Layout … to display more columns, for example, the index priority or the index ID on the TREX side.

If you double-click a row, you can launch a dialog box that displays the last successful delta indexing and the last successful complete indexing for the selected index. This is of particular interest if errors occurred during the last indexing.

Overview of Functions

The menu functions are described below. You can also perform many of these functions with pushbuttons or from the context menu in the table.

Function	Description
Create/Delete/Activate/Deactivate Index	Edit indexes These are integrated functions that not only create and delete the index in the TREX system, but also update the relevant Customizing entries and generate or delete the corresponding table rows in the index monitor. When creating the object index, the system checks in the Customizing table whether it should also index the relations for this object. If yes, the system checks whether the corresponding relations interface is implemented. If this condition is also met, the system creates the following: ●        The object index ●        A relations index ●        A compound index in the TREX system The compound index contains information about which object indexes and relation indexes belong together, and the relationships that exist between the indexes. If one of these indexes already exists, the system creates only the missing indexes.
Start Full Indexing/Start Delta Indexing	Start additional delta or full indexing job immediately The indexing program is called COM_SE_DISPATCHER. For more information about using it, see the program documentation.
Edit
Refresh Display	Updates the index monitor display.
Process Queues	After transferring the objects to be indexed to the TREX system, the TREX system normally completes the multi-level inbound processing automatically. If you establish in the index monitor that a constant number of objects remain in the Queue: In Process column for a longer period of time, you can use the Flush Queues function to trigger processing.
Goto
Customizing	This path takes you to the associated branch in the Implementation Guide (IMG) or directly to the different IMG activities.
TREX Admin	Launches the TREX admin tool. For information about this tool, see TREX Admin Tool in the SAP System.
Jobs	Starts the job overview for the indexing program.
Spool List	Displays the spool list for the last indexing.
SES Log	Displays the application log of the search engine service.
Utilities
Reactivate Change Pointers/Delete Change Pointers/Delete Object from Index	Here you can find utility programs for the following functions: ●      Reactivate Change Pointers Program COM_SE_CPOINTER_REACTIVATE ●      Delete Change Pointers Program COM_SE_CPOINTER_DELETE ●      Delete Object from Index Program COM_SE_DELETE_FROM_INDEX For more information about the scope and handling of these programs, see the respective program documentation.

Activities

The most frequent activities on the admin UI are:

●      Changing and optimizing the Customizing parameters for each index.

To do this, navigate in the menu as follows: Goto ® Customizing ® Business Objects and Indexes.

●      Continuous monitoring of periodic indexing.

During a longer continuous indexing run, you can refresh the display repeatedly to monitor progress in the multi-level indexing process.

If you notice longer runtimes during indexing of a particular object type, you can click the affected index during indexing to launch a dialog box that displays the runtime of the last successful indexing as a comparison.

●      Error Handling During Indexing
