Specify the following settings for the analysis:

  • Use optimization. Optimization means that, for example, analysis of a check item ends as soon as a result for the check item evaluation is sufficient.

    Recommendation Recommendation

    Set the flag to keep the load on the system as low as possible during the analysis.

    End of the recommendation.
  • Include Identifying Check Items. The flag is set by default. You must include these check items to get results for the analysis structure node from the analysis.

  • Include Informative Check Items. The flag is not set by default.

    Recommendation Recommendation

    Informative check items are not required for the evaluation of the structure nodes. Only include informative check items in the analysis if you are sure that you need them.

    SQL check steps generate a high system load. It is therefore a good idea to include SQL check steps in informative check items.

    End of the recommendation.
  • Threshold Value. Define a global threshold value for the analysis. This global value overwrites all threshold values where the the value for assigned check steps is set to zero.

  • System load check steps, for example, dialog, background, or spool. All types are included by default. Select one or more entries from the selection list, to change the default setting.

  • SQL Check Steps.

    • If the analysis includes SQL check steps, the Very expensive SQL statements check box is ready for input. The flag is set by default.

      If you do not select the checkbox, the system does not execute any SQL check steps that are classified as especially costly.

      Lowering the System Load

      SQL check steps can generate a heavy system load.

      • Check whether it is necessary for the analysis to execute SQL statements (for example to check the contents of database tables).

      • Ensure that the time and resources allocated by your system administrator are sufficient for complete execution of the SQL statements. How precisely you are able to estimate the expected system load will depend on your experience with executing SQL statements.

      End of the recommendation.
    • Descriptive Result Limit: If SQL check steps have to be carried out, you can limit the number of result lines for each SQL check step. This allows you to reduce the data volume and thus also the execution time and system load.

  • Object Usage – Not in Analysis: Select the object types for which you wish to display usage data, but which is not or not yet part of your analysis. The usage data is transferred during the SAP EarlyWatch Alert (EWA), for example. You can display the data in the analysis results under Object Usage and create new check rules for it. For more information, see Display Object Usage.

    • Under Unused Customer Objects, select the types of objects that you have created yourself and whose usage you wish to check. The customer objects that are not used are displayed in the analysis results under Object Usage.

      Note Note

      If you include unused customer objects in the display, the analysis results on the   Object Usage   Not in Analysis   tab may show more objects than are defined for the object type.

      End of the note.
    • Under Most-Used Objects you set for each object type the number of most-used objects for which you want to display the usage data. The most-used objects include SAP objects as well as customer objects.

      Depending on the object type you can set maximum values of 0 (default), 100, 1,000 or 10,000.

      Example Example

      For the documentation of your solution, focus on the top 100 most-used transactions.

      End of the example.

      Note Note

      Including customer objects requires RFC connections to the corresponding systems.

      End of the note.

    Recommendation Recommendation

    Avoiding Memory Problems

    You can avoid memory problems in the following ways:

    • Reduce the number of object types selected under Unused Customer Objects

    • Reduce the number of object types selected under Unused Customer Objects

    • Reduce the number of analyzed periods

    End of the recommendation.
