Did you set unix group during Oracle iDA install?

Hi ​@CV_GK 

The CV version is 11.40.19

DB: Oracle 19.22

OS: RedHat 7.9

Below is a what I see in the RMAN log:

Not sure what is that lib libCvDllFilter.so about, any clue?

Hi ​@Hansel.Flores 

Please share output of below command from oracle client's RMAN prompt

run

{

allocate channel c0 type 'sbt_tape';

release channel c0;

}
