Modifying the criteria

Edit online

The criteria that you use to perform historical impact analyses restrict the engine to a specified number of implementation tasks, and to a time period during which to search for tasks. This product ships with default values for each of these criteria, which are defined as system properties. You can modify these criteria to meet the requirements of your historical analyses.

About this task

To view and modify the criteria that the engine uses to perform historical impact analyses, perform the following steps:

Procedure

  1. Click Open menu > System Configuration > Platform Configuration > System Properties to open the System Properties application.
  2. Click Filter, type pmchg in the Property Name field, and press the Enter key to display a list of system properties that are defined for Change Management.

    The following three properties establish search criteria for historical impact analysis:

    pmchg.ia.impactTasklimit
    Specifies the maximum number of tasks to examine for historical impact analysis results. The value provided for this property in the shipped product is 5, meaning that the engine will find up to five implementation tasks that contained the target CI or asset for which you want impact data.
    pmchg.ia.impactTimelimit
    Specifies the number of days to go back from the current date to search for the implementation tasks. The value provided for this property in the shipped product is 365, meaning that the engine will go back one year as it searches for implementation tasks that contained the target CI or asset. Tasks that were performed more than 365 days ago are not examined.
    pmchg.historical.impacts.maxrecords
    Specifies the maximum number of targets that the Change historical impact analysis will process.
