Tab Page: Metadata Indexing

Definition

Under Administration in the Data Warehousing Workbench, you can use Metadata Search/Documents on the Metadata Indexing tab to check the required settings for the metadata search, and to index the metadata.

Structure

The Metadata Indexing tab has the following fields and functions:

Status Display

Field	Description
Status of Search Engine	The system indicates whether the TREX server is configured correctly. Display options: OK/Not Fully Installed
Status Search/Indexing	The system displays the indexing and search status. Not yet indexed Indexing is running Indexing complete
RFC Connection	The system displays the current RFC connection to the TREX search engine. If you want to use a different RFC connection, use input help in the BW system to select one.

Note

For more information about installing the search engine and creating and entering an RFC connection, see Start of the navigation path SAP Reference IMG Next navigation step SAP Customizing Implementation Guide SAP NetWeaver Business Warehouse Connectivity of TREX End of the navigation path .

Indexing

In general, an indexing with default settings is sufficient.

By choosing Schedule Initial and Delta Indexing, you start indexing with the default settings: The system performs an initial indexing run, followed by delta indexing every five minutes.

Delta Indexing with Default Settings

Field	Description
Status of Indexing Job	The system indicates whether the indexing job has been scheduled. Display options: scheduled/not scheduled
Start Date	The system displays the date and time of the scheduled execution of the indexing job.
Frequency	The default value for the frequency of delta indexing is every five minutes.

Field

Description

Status of Indexing Job

The system indicates whether the indexing job has been scheduled.

Display options: scheduled/not scheduled

Start Date

The system displays the date and time of the scheduled execution of the indexing job.

Frequency

The default value for the frequency of delta indexing is every five minutes.

If you want to make additional settings, use Special Functions to choose expert mode.

The following functions are available in expert mode:

Schedule Delta Indexing

The Start Time dialog box appears. Confirm that the indexing program should run as a regular job. This ensures that the index queue is processed regularly.

Initial Indexing

The Initial Index for TLOGO Objects in TREX Server screen appears.

You can specify whether to index one or all object types, active or content objects.

You can trigger a new index by choosing Delete Data Indexed Before.

In Expert Mode, you can enter one or more object names and languages and start indexing again with restricted criteria. In the default setting, the logon language is predefined.

Configure Object Types for Search

A screen with a list of all the object types relevant to the BW metadata search and the related search/index status appears. The selected object types are available for indexing and search.

You can exclude individual object types from the search or indexing by deselecting the flag. The system can then only search for the object type in a database search. This is a slower, case-sensitive search option that does not support searching for attributes.

If you reselect active objects for the search or indexing, you should perform an initial indexing.

Caution

Note that an object type is available for indexing and search after it has been selected. However, the last change made to the object type is only implemented in the index when you perform initial indexing again.

Delete index

If you delete the index, the TREX search is deactivated. (The indexing status changes to Not Indexed). When a search request is made, the system reads from the database; this requires considerably more time.

To reactivate the TREX search, you need to perform initial indexing again.

Monitoring
