Repository structure

Member IRMREPIN of the product sample library contains a job to allocate the repository. During installation of RMGR, the repository data set is created and populated with default required records. As the people in your environment work with RMGR, other records are created.

The following types of records are required:

• An RMGR environment record for each RMGR started task or job that will use the repository
• An IMS environment record or sharegroup environment record for each IMS system or each sharegroup of IMS systems that will use the repository
• A system-default profile record that defines processing options to use during recovery management functions if no other profile record is selected

The following types of records are created during operations with RMGR:

• Elemental group records that define groups of recoverable objects (IMS database data sets, Fast Path areas, and HALDB partitions)
• Connecting group records that define groups of elemental groups
• Object records that identify recoverable objects
• Utility records that provide information about the utilities that you will use for performing recovery tasks
• Profile records that define processing options to use during recovery management functions
• Status records that contain information about individual executions of recovery management functions
• Recovery Advisor records that contain information about detected events
• Recovery Extensions feature records that manage information about additional recovery assets
