prepares the environment to start the restore, and issues the RMAN restore command.
RMAN checks the recovery catalog (if one is used) or the control file to gather the
information about the Oracle backup objects. It also contacts the Oracle Server
processes, which initialize the restore through MML. MML establishes a connection
with the Restore Session Manager and passes along the information about which
objects and object versions are needed.
The Restore Session Manager checks the IDB to find the appropriate devices and
media, starts the General Media Agent, establishes a connection between MML and
the General Media Agent, and then monitors the restore and writes messages and
information regarding the restore to the IDB.
The General Media Agent reads the data from the backup devices and sends it to
the Oracle Server processes through MML. The Oracle Server Processes write the
data to the disks.
The concept of Oracle integration, data and the control flow are shown in Figure
2 on page 38, and the related terms are explained in the following table.
