Starting Indexing of ConnectorsLocate this document in the navigation structure

Use

To make the objects in the connectors available in the search, you have to start or schedule indexing for the new connectors.

Indexing runs either as full indexing or as delta indexing. This depends on whether or not the underlying model supports delta transfers, and the settings your define for indexing.

Prerequisites

You have created connectors.

Process

Starting Indexing

  1. You are in the administration cockpit.

  2. Choose the connectors that you want to schedule indexing for and then choose Start of the navigation path Actions Next navigation step Schedule Indexing End of the navigation path.

  3. Below Object Type, select one or more search and analysis models.

    Note

    The entry screen allows you to make settings for more than one model at the same time.

  4. To trigger indexing immediately, select the Start Immediately flag. Alternatively, you can schedule indexing for a later time. To do this, specify a start time.

  5. If you want to do a full indexing run, choose the Mode for Full Indexing.

    When you select a mode, you decide whether the existing index is retained during full indexing and updated row by row or completely emptied and then refilled.

    If you do not choose a mode, the system performs delta indexing if possible; otherwise it performs full indexing. In the case of delta indexing, during the first run, the system performs full indexing for a prepared connector with an empty index and then delta indexing directly afterwards. During the subsequent runs, delta indexing is performed each time.

    Note

    Note the following information for the indexing of connectors for delta-compatible DataSources:

    For the first indexing run, two requests are generated: One request for the full indexing and one request for the subsequent delta. For delta indexing in subsequent runs, one delta request is generated for each run. You can display the requests in the delta queue monitor.

    More information: Monitoring Delta Queues

  6. Optional: Define whether or not Real-Time Indexing is to be used.

    For more information about setting up and monitoring real-time indexing, see Controlling Real-Time Indexing.

  7. Optional: If you want to perform indexing regularly, for example, for delta-compatible models, enter a recurrence period.

    Example

    If you specify tomorrow's date at 01:00:00 and one day as the recurrence period, the system performs the indexing run from the next night onwards, every subsequent night at one o'clock.

  8. Choose OK to activate the indexing schedule.

Note

In transaction RZ11, you must assign the value 4 to the auth/new_buffering profile parameter so that changes in user data are available without delay and can be subsequently indexed. Then schedule object USER_AUTHORITY for delta indexing. Note that real-time indexing is not possible for this object.

If you want to index documents that contain hidden text, note the additional information in SAP Note 604635 Information published on SAP site.

Notes on Troubleshooting for Delta-Compatible Models

In you have to reset indexing of connectors during troubleshooting, proceed as follows:

  1. Schedule a one-off indexing run, for which you choose the Delete Index Content option as the Mode for Full Indexing. This empties the index entirely and builds it again.

  2. To ensure that periodic delta indexing is performed rather tha periodic full indexing, you then schedule the indexing periodically again and without choosing the Full Indexing Mode.
