Repository Snapshot Prerequisites
To be able to use repository snapshots, you must:
• check that the repository log is activated (default value).
For more details on repository log activation, see Managing logfiles.• select the "Authorize management of repository snapshots in the workspace" (Options > Collaborative Environment)
This option is not necessary if you have used the Administration application to create repository snapshots.• set up a procedure for taking account of repository snapshots before deletion of historical data.
A repository snapshot identifies an archived state of the repository. When an archived state of the repository has been deleted, it is no longer possible to create a repository snapshot corresponding to this state. It is therefore important to take management of repository snapshots into account when deleting historical data (in the repository contextual menu, RDBMS Administration > Shrink unused repository historical data).
For more details, see "Repository - RDBMS Installation Guide", "HOPEX Historical Data Cleanup". You do not require the Administration application to create repository snapshots. Your associated profile must have the option "Enable repository snapshots management in the workspace" (Options > Collaborative Environment).
