Path or oracle home variable is not properly set for the database from which rman try to execute
Solution:
Set the correct variables
[oracle@orcl19x apex]$ export PATH=/data01/product/19.0.0/bin:/usr/sbin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/oracle/.local/bin:/home/oracle/bin export ORACLE_HOME=/data01/product/19.0.0
Relink binaries from the correct oracle home
