+Example lowest number is 123456
+<code>
+RMAN> BACKUP INCREMENTAL FROM SCN 123456 DATABASE FORMAT 'F:\ad-hoc_backup\CPHG\ForStandby_%U' tag 'INCR_STANDBY';
+</code>
+Copy backup file to the standby database server. \\
+<code>
+RMAN> CATALOG START WITH 'F:\adhoc_backup\CPHG';
+RMAN> RECOVER DATABASE NOREDO;
+</code>
+Backup the control file on the primary server. \\
+<code>
+RMAN> BACKUP CURRENT CONTROLFILE FOR STANDBY FORMAT 'F:\ad-hoc_backup\CPHG\standby.ctl';
+</code>
+Copy control file backup to the standby server. \\
+If database locations are different on the standby server record the names ...
+<code>
+RMAN> REPORT SCHEMA;
+RMAN> SHUTDOWN IMMEDIATE ;
+RMAN> STARTUP NOMOUNT;
+RMAN> RESTORE STANDBY CONTROLFILE FROM 'F:\adhoc_backup\CPHG\standby.ctl';
+SQL> SHUTDOWN;
+SQL> STARTUP MOUNT;
+RMAN> CATALOG START WITH '<DATAFILE_LOCATION>';
+RMAN> SWITCH DATABASE TO COPY;

+If this is a Data Guard configuration then clear the standby redo log groups. \\
