SAP NetWeaver Enterprise Search allows you to index data that exists in back-end systems in real time.

Note Note

The back-end system must also support real-time indexing

End of the note.

From the administration cockpit, you can launch an administration UI that you can use to control and monitor real-time indexing.

You can define the time after which the daemon process interrupts its work if it does not receive any more data from the back-end system. If the back-end system transfers new data again, the daemon process restarts its work and triggers the system to index new or changed data.

Prerequisites

In the administration cockpit, you have activated real-time indexing for a search object connector:

Choose a search object connector and then choose   Actions   Schedule Indexing   and select the Real-Time Indexing flag.

Procedure

Once you have chosen the search object connectors for real-time indexing, you must start the daemon process that performs real-time indexing on the back-end system.

  1. Launch the administration cockpit.

  2. Choose   System Settings   Control Real-Time Indexing  .

  3. In the case of a hub installation: In the Logical System parameter, select the back-end system for which you want to configure automatic indexing.

    Note Note

    If you launch the administration cockpit in an Embedded Search system, the list contains only the local system.

    End of the note.

  4. Start the daemon process on the back-end system.

    Note Note

    You should stop the process only for support purposes or debugging.

    End of the note.

  5. Optional: Perform one of the tasks listed below:

    • Change the time interval for the maximum idle time.

    • Monitor the status of the daemon process.

    • Monitor indexing.

    • Display the job log.

  6. Choose OK to close the window or choose Cancel to leave the screen without saving your changes.

Changing the Time Interval for the Maximum Idle Time

If you want to change the predefined default value for the idle time, specify in the Maximum Idle Time parameter the time in seconds after which the daemon process is to interrupt its work. Choose Apply to confirm your entry.

Monitoring the Status of the Daemon Process

In the upper screen area, the system displays the status of the daemon process.

Process Status

Description

Starting

The process is starting.

Auto-Restarting

The process is restarting automatically after a stop.

Running

The process is running.

Stopping (Processing Last Job)

The process is processing the last package and will stop afterwards.

On Hold

The process was suspended.

Temporarily Stopped (Idle Time Exceeded)

The process pauses and continues once the idle time has expired.

Not Running

The process has not been started because there are no search object connectors in the system that support the type of indexing.

Temporary Error: Communication Failure

There is a temporary error in the communication between the systems; note the error message.

Technical Error

There is a technical error; note the error message.

Communication Error: Back End not Reached

There is an error in the communication between the systems. The back-end system could not be reached.

Real-Time Indexing not Supported

This type of indexing is not supported by the system.

Debug Mode

The system is in debug mode. The process is not running and indexing is not taking place.
Monitoring Indexing

In the Indexing Changes in "System" table, all search object connectors and the following information is displayed:

  • Extraction Status

  • Queue Size

    Specifies the number of objects that contain changes.

  • Number of Objects in Editing

  • Number of Objects with Errors

Choose the Refresh link to display the current status.

Displaying the Job Log

In the lower area of the window, you can see the job log. This displays all status changes and error messages that have occurred since the system was started.
