Backup with RMAN - 19c Oracle Database

Hi Experts,

uatcdb is CDB

UATDB is pdb

We have a container database with single pdb

We are configuring the backup.

[orauat@erpuatdb2 ~]$ cd /u02
[orauat@erpuatdb2 u02]$ cat 19c.env
export ORACLE_HOME=/u02/UAT19CBASE/19chome
#export PATH=$PATH:$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$ORACLE_HOME/perl/bin
export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$ORACLE_HOME/perl/bin:$PATH
export ORACLE_BASE=/u02/UAT19CBASE
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib

export ORA_NLS10=/u02/UAT19CBASE/19chome/nls/data
