ERT Parameters

Client-wide variables that contain the relevant parameters for the Estimated Runtime (ERT) calculation.

The ERT parameters cover the following variables:

ERT_ADAPTIVE

  • Description: Activation or deactivation of adaptive ERT calculation for the entire Client

    Deactivating ERT_ADAPTIVE means that the tasks for which the dynamic ERT method Adaptive has been defined in the Runtime Page will use the alternative method ERT_ADAPTIVE_FALLBACK_METHOD.

  • Allowed values: Y and N

    • Y: Activates adaptive ERT calculation

    • N: Deactivates adaptive ERT calculation

  • Default value: N

  • Restart required: No

ERT_ADAPTIVE_DEFAULT_CONTEXT

  • Description: Information that should be considered for adaptive ERT calculation. You can also specify any object attributes; these must be separated by semicolons.

  • Default values: PARENT_ALIAS;HOST;FT_DST_HOST;FT_SRC_HOST;START_TIME

  • Restart required: No

ERT_ADAPTIVE_FALLBACK_METHOD

Also used if the JWP is not available to handle adaptive ERT calculation

  • Description: Alternative method for calculating the ERT if adaptive calculation is not possible

  • Allowed values:

    • FIXED

      Static predefined value

    • AVERAGE

      Dynamically retrieved average value

    • LINEAR REGRESSION

      Dynamic value, based on linear regression

    • MAXIMUM

      Dynamic value, based on the longest actual runtime

  • Default value: LINEAR REGRESSION

  • Restart required: No

ERT_CALCULATION

The Automation Engine can calculate the estimated runtime (ERT).

  • Description:

    Deactivating ERT calculation can slightly improve the performance of your Automation Engine. Despite this, you can still calculate the ERT of all objects subsequently in the database. Use the AE DB Load utility for this purpose and load the UC_UPD_ESTIMATE_ERT.TXT file. It depends on the number of objects that are involved how long the ERT calculation process takes.

    The file UC_UPD_ESTIMATE_ERT.TXT contains a line at its end that activates the ERT calculation function for the whole AE system. You can specify a client if ERT calculation should only take place in a specific Client.

    Example:

    ESTIMATE_ERT 1000

    All keys below that start with "ERT_" form the default values for ERT calculation. You can adjust them in the Runtime page of the individual objects, if required.

  • Allowed values:

    • BATCH

      Deactivates ERT calculation

    • IMMEDIATE

      Activates ERT calculation

  • Default value: IMMEDIATE

  • Restart required: No

ERT_CHECK_COUNT

  • Description: Number of runs that should be evaluated

  • Allowed values: Two-digit value between 1 and 25

  • Default value: 20

  • Restart required: No

ERT_CORR_PERCENT

  • Description: Positive correction value in percent

  • Allowed values: Up to three-digit values

  • Default value: 0

  • Restart required: No

ERT_FRT

  • Description: Fixed value for the ERT in seconds

  • Allowed values: Up to three-digit values

  • Default value: 0

  • Restart required: No

ERT_IGNORE_PERCENT

  • Description: Deviation in percent

  • Allowed values: Up to three-digit values

  • Default value: 0

  • Restart required: No

ERT_METHOD

  • Description: Method that is used to evaluate the ERT

  • Allowed values:

    • FIXED

      Static predefined value

    • AVERAGE

      Dynamically determined average

    • LINEAR REGRESSION

      Dynamic value based on linear regression

    • MAXIMUM

      Dynamic value based on the longest actual runtime

    • ADAPTIVE

      Intelligent ERT calculation that considers various factors and runtime parameters

  • Default value: LINEAR_REGRESSION

  • Restart required: No

ERT_MINIMUM_COUNT

  • Description: Minimum number of runs that should be considered for deviation

  • Allowed values: Two-figure value between 1 and ERT_CHECK_COUNT

  • Default value: 0

  • Restart required: No
