Cause

Oracle was upgraded/patched and the Operating system user configured to do backup does not have permissions to open the following Oracle client libraries
  
-rwx------. 1 oracle oinstall   2247120 Apr 14 03:38 libasmclntsh19.so
-rwx------. 1 oracle oinstall   8056664 Apr 14 03:38 libclntshcore.so.19.1
-rw-------. 1 oracle oinstall   1771463 Apr 14 03:38 clntshcore.map
-rwx------. 1 oracle oinstall  81182280 Apr 14 03:38 libclntsh.so.19.1
-rw-------. 1 oracle oinstall   6165285 Apr 14 03:38 clntsh.map
PPDM must be able open the previous Oracle client libraries to be able to connect to the Oracle Database.

Resolution

Change permissions to the Oracle client libraries so that the Oracle user has permission to open them and connect to  the Oracle Database.
 
Example: 
chmod 755 *clnt*
The above is only an example. Consult the DBA before changing permissions on the Oracle libraries.
