(SmWaitForNewClient omnirc global variable) and completes the backup session, as long as no backint is started within this time frame.

A backup session using RMAN mode differs from a backup session in backint mode in step 3. See Figure 2-3 on page 156 for details.

BRBACKUP starts RMAN, which then connects to the Data Protector Database Library via the Oracle Server processes. The Database Library provides a connection to the Data Protector BSM, which starts General Media Agents and establishes a connection between the Oracle Server and General Media Agents.

The data transfer begins at this point. The Oracle Server sends data to General Media Agents, which then write the data to the media.

Once the Oracle Target Database’s data files have been written to the media, the respective Oracle Server processes are completed, and so, subsequently, is RMAN. The backup control is now returned to BRBACKUP, which starts the first backint command to back up the Oracle Target Database’s control file and the SAP R/3 log files. Archive logs are backed up in the same manner as in backint mode.
