You can use ignore rules to:

1. Reduce the time taken for a database comparison operation by reducing the number of objects that are analyzed.
2. Tailor which objects that need to be considered as part of a specific project

Note that any objects that are filtered out using an ignore rule can no longer be included in a subsequent deployment script.

The configuration of ignore rules is saved when you save a Data Compare project. Individual ignore rules files can also be saved to disk for later use, and can also be used as an input to the Data Compare for Oracle command line using the /ignoreRules switch.

Configuring ignore rules

Ignore rules are configured per-object type, using a include/exclude expression. A description of the required syntax along with examples can be found here.
