RRC file

The IFS Configuration Builder can fetch files for the build from either a reference directory structure, the Release Repository, or another file based structure.

The RRC file (Release Repository Catalog) determines from where to fetch the components. If you select to fetch your components from an release archive, a RRC file is automatically generated for you, and saved into your profile. Basically the RRC file is the master control file for the build.

The RRC file is a semi-colon separated text file that provides the Configuration Builder with the mapping of component version to the fetch location as well as what kind of fetch to do. The RRC file consists of the following pieces of information:

Component	Release	Component Type	Release Type	Release Sequence	Location	Archive Type
ACCRUL	Accrul 9.1.0	BASE	CORE	0	\\sitefs1\Archive\Accrul\Core\Accrul 9.1.0\	DISK

Component: the name of the component.
Release: the release of the component. Each release name must be unique.
Component Type: an IID defining the type of the component.
Release Type: defines the type of component release. Release type CORE, means a core release from R&D. The release types other than CORE can be freely defined for a release repository. This column is used to define the order component releases are fetched. CORE release will always be first to fetch.
Release Sequence: a numbering sequence. This column is not used in current version of the Configuration Builder and may be simply set to 0.
Location: a path to the physical location on disk that contains the component release. The named directory contains a sub-folder, named according to the component, below which all files of the component release can be found. If an update exists for the release, UPD[n] folders can exist parallel with component folder on Archive.
Archive Type: indicates that the Location specified is a path to a file system. Only supported value is DISK

A experienced technician can create an RRC file from scratch or by editing an RRC file from an existing release. You can find the RRC file located in the _ConfigBuild directory in the release archive, please read the instructions next to the RRC file on how to adopt it for your environments.

The ability to specify more than one version of a component in your RRC file is a very powerful feature. Consider the following example, which shows a portion of an RRC file.

Component	Release	Component Type	Release Type	Release Sequence	Location	Archive Type
ACCRUL	Accrul 9.1.0	BASE	CORE	0	\\sitefs1\Archive\Accrul\Core\Accrul 9.1.0\	DISK
ACCRUL	Accrul 9.1.0-XX	BASE	XX	0	\\sitefs1\Archive\Accrul\XX\Accrul 9.1.0-XX\	DISK

In this example, XX designates a customized release. Since the Configuration Builder can fetch multiple versions of a component in a specified order, the tool can create overlays, where the component of the first release type in the fetch order list is fetched and subsequent fetches will overwrite files in the <workspace catalog>\components folder.
