Rules and guidelines for parameter files

Rules and guidelines for parameter files

Data Integration
uses the following rules to process parameter files:
  • If a parameter is not defined in a the parameter file,
    Data Integration
    uses the value defined in the task.
  • If a parameter value is defined more than once in the same section,
    Data Integration
    uses the first value.
  • If a parameter value is another parameter defined in the file,
    Data Integration
    uses the first value of the variable in the most specific scope. For example, a parameter file contains the following parameter values:
    [GLOBAL] $$ffconnection=my_ff_conn $$var2=California $$var6=$var5 $var5=North [Default].[folder5].[sales_accounts] $$var2=$var5 $var5=south
    In the task "sales_accounts," the value of "var5" is "south." Since var2 is defined as var5, var2 is also "south."
  • If a task is defined more than once,
    Data Integration
    uses the most recent section after processing the file top-down.
  • The value of a parameter is global unless it is present in a section.
  • Data Integration
    ignores sections with syntax errors.
