Comparing Repository Objects -- from Informatica HELP

Comparing Repository Objects


The Repository Manager allows you to compare two repository objects of the same type to identify differences between the objects. For example, you can compare two sessions to check for differences. When you compare two objects, the Repository Manager displays their attributes.

You can compare objects across folders and repositories. To do this, you must have both the folders open. You can compare a reusable object with a non-reusable object. You can also compare different versions of the same object. For more information about versioned objects, see Comparing Versions.

To compare objects, you must have read permission on each folder that contains the objects you want to compare.

You can compare the following types of objects:

  • Designer objects. You can compare Designer objects, such as sources, targets, transformations, mapplets and mappings. For more information about comparing objects in the Designer, see the Designer Guide.
  • Workflow Manager objects. You can compare Workflow Manager objects, such as tasks, sessions, worklets, and workflows. You can compare schedulers and session configuration objects in the Repository Manager, but not in the Workflow Manager. For more information about comparing objects in the Workflow Manager, see the Workflow Administration Guide.

You can compare instances of the same type in detail. For example, if the workflows you compare contain worklet instances with the same name, you can compare the instances to see if they differ. You can compare instances of sessions and tasks in a workflow or worklet comparison. You can compare instances of mappings and transformations in a session comparison. Further, you can compare instances of the same type within a mapping or mapplet comparison.

You cannot compare objects of different types. For example, you cannot compare a source definition with a target definition.

Use the following procedure to compare objects.

To compare repository objects:

  1. In the Repository Manager, connect to the repository.
  2. In the Navigator, select the object you want to compare.

    Tip: To compare the first two objects in a node, select the node.
