Analyzing Cache NotificationsLocate this document in the navigation structure


To ensure that the relevant Integration Engines have quick access to the contents of the Integration Directory at runtime, the information required is loaded into corresponding caches. Caches also contain the runtime-relevant data from the System Landscape Directory.

The cache is updated by different events:

  • Activation of change lists in the Integration Directory

  • Change lists that contain runtime-relevant objects being activated in the Enterprise Services Repository

    This includes mapping objects, adapter metadata, and integration processes.

The cache notifications enable you to display which notification about released changes was transferred to the relevant cache instances. You can also display whether the data was updated successfully or not. If a notification or cache update fails, you can determine the cause of the error.

The following can be cache instances:

  • Integration Server

  • Adapter Engine

  • Business systems


  1. In the menu bar, choose Start of the navigation path Environment Next navigation step Cache Notifications End of the navigation path.

    The events that triggered a cache update are displayed in the Notifications of Released Change Lists frame.


    You can use the criteria cache instance, notification period, and author to restrict the display.

    Cache notifications and cache updates are displayed on multiple tab pages in the Integration Directory. For more information, see the table below.

  2. To update the cache again, select the corresponding line and choose Repeat Cache Update for Instance ( ).

Cache notifications can fail for a variety of reasons. You can test the cache connectivity in the Runtime Workbench.

Tab Page



Contains a list of the released changes that have resulted in a cache notification and cache update.

The system displays the following information for each event:

  • The cache instance that is affected by the change.

  • Status and time of the successful cache update.

  • Status and time of the successful cache notification.

  • Underlying change

    The Type field shows the type of change.

    Depending on the type of change, the Identifier (GUID) column displays the identifier of the change list or the imported software component version.


Contains information about the cause of the error when notifications or cache updates fail.

In the Problems that Occurred During Cache Update frame, the changes that resulted in the notification or cache update failing are listed in a table.

You can find the following information about each problem.

  • The type of problem is specified in the Problem column.

    The context can have the following values:

    • Notification : This is a notification error.

    • Part Update: Collect Data : This is an error in the Integration Directory.


      An Integration Directory object has been deleted and therefore cannot be read.

    • Data Evaluation : This is a cache-instance error.

  • The Affected Object column displays information about the object that caused the error.

    The Detailed Problem Description column displays a description of all selected problems.

Object views

Shows the cache status for each individual object.

This tab page displays the cache status for each individual object in the cache.

If, for example, objects from a change list were not updates in the cache, you can use this view to determine which objects are affected and to find the cause of the error.


You can also display which cache a particular object was distributed to and analyze the status. To do this, open the object and in the main menu bar of the object editor choose Start of the navigation path <Object Type> Next navigation step Display Cache Status End of the navigation path.
