.fedfile) and merge any differences.
3 minute read
In Policy Studio, you can compare the currently loaded API Gateway configuration with a configuration stored in a deployment package (
.fed file). You can also merge any differences between the configurations.
Differences between configurations are identified as additions, deletions, or conflicts. When merging configurations, you can choose which differences to merge.
NoteThe currently loaded configuration can only be compared with a configuration stored in a deployment package (
.fed) or in a server configuration file (
.xml). You cannot compare against a policy package (
.pol) or environment package (
Compare and merge configurations
To compare the currently loaded configuration against the configuration in a
file, follow these steps:
- Click the Compare button on the Policy Studio toolbar.
- In the Comparing target with
field, click the Browse
button to choose a
.fedfile to compare the configuration with.
- Enter the passphrase for the configuration, if one has been set, and click OK .The configurations are compared and the results are displayed in a tree view. Only entities with differences are shown.
- To see detailed differences, click a configuration entity in the tree. The differences for that entity are displayed in the Difference Details pane.
- To merge differences into the currently loaded configuration, select the check box next to each difference to be merged, and click the Merge button at the top right of the window.
NoteIf you modify the currently loaded configuration after the Compare and Merge tab is opened, click the Refresh button to refresh the comparison and show any new differences.
The following figure shows the result of a comparison:
The Difference Counts pane shows the number of differences in total, the number of additions, the number of deletions, and the number of conflicts.
The Differences tree view shows all of the differences in the configuration entities:
- Entities with green plus icon are additions. These entities exist in the
.fedfile but not in the currently loaded configuration.
- Entities with a red minus icon are deletions. These entities exist in the currently loaded configuration but not in the
- Entities with a yellow warning icon are conflicts. These entities exist in both configurations but are not the same.
The Difference Details
pane shows the values of the fields in each configuration when you click on an entity in the tree view. The second column shows the values of the fields in the
file, and the third column shows the values of the fields in the currently loaded configuration. The fields that are different in each configuration are highlighted.
