Advanced properties

Configure advanced properties to define how the Rank transformation processes data. Configure advanced properties on the Advanced tab.
Note: The properties that appear in the transformation depend on the mapping type.
Configure the following properties:
Property
Description
Cache Directory
Directory where Data Integration creates the data cache and index cache files. By default, Data Integration stores the cache files in the directory entered in the Secure Agent $PMCacheDir property for the Data Integration Server.
If you change the cache directory, verify that the directory exists and contains enough disk space for the cache files.
To increase performance during cache partitioning, enter multiple directories separated by semicolons. Cache partitioning creates a separate cache for each partition that processes the transformation.
Default is $PMCacheDir.
Rank Data Cache Size
Data cache size for the transformation. Select one of the following options:
  • - Auto. Data Integration sets the cache size automatically. If you select Auto, you can also configure a maximum amount of memory for Data Integration to allocate to the cache.
  • - Value. Enter the cache size in bytes.
Default is Auto.
Rank Index Cache Size
Index cache size for the transformation. Select one of the following options:
  • - Auto. Data Integration sets the cache size automatically. If you select Auto, you can also configure a maximum amount of memory for Data Integration to allocate to the cache.
  • - Value. Enter the cache size in bytes.
Default is Auto.
Tracing Level
Detail level of error and status messages that Data Integration writes in the session log. You can choose terse, normal, verbose initialization, or verbose data. Default is normal.
Transformation Scope
The method in which Data Integration applies the transformation logic to incoming data. Select one of the following values:
  • - Transaction. Applies the transformation logic to all rows in a transaction. Choose Transaction when the results of the transformation depend on all rows in the same transaction, but not on rows in other transactions.
  • - All Input. Applies the transformation logic to all incoming data. When you choose All Input, Data Integration drops transaction boundaries. Select All Input when the results of the transformation depend on all rows of data in the source.
Default is All Input.
Case Sensitive String Comparison
Specifies whether Data Integration uses case-sensitive string comparisons when it ranks strings. To ignore case in strings, disable this option. Default is enabled.
Optional
Determines whether the transformation is optional. If a transformation is optional and there are no incoming fields, the mapping task can run and the data can go through another branch in the data flow. If a transformation is required and there are no incoming fields, the task fails.
For example, you configure a parameter for the source connection. In one branch of the data flow, you add a transformation with a field rule so that only Date/Time data enters the transformation, and you specify that the transformation is optional. When you configure the mapping task, you select a source that does not have Date/Time data. The mapping task ignores the branch with the optional transformation, and the data flow continues through another branch of the mapping.
Default is enabled.
