The UPGRADE_SETUP procedure validates the default parameter values that are used during the upgrade and creates the IN_DB_UPGRADE_CONTROL_UPGRADE table, which is used to save the default parameter values for the duration of the upgrade. This procedure can be re-executed to update the default upgrade parameter values in the control table or to recreate the IN_DB_UPGRADE_CONTROL_UPGRADE table if necessary.
If the starting schema version for the upgrade is less than version 7.5.0.0 then the UPGRADE_SETUP procedure will automatically execute the following synchronization procedures to facilitate the uptime steps for the IN_DOC table upgrade:
The SYNC_SETUP procedure, to create and populate the IN_DB_UPGRADE_CONTROL_SYNC table.
The SYNC_SETUP_IN_DOC procedure, to create the synchronization framework.
