Dedupe direct for oracle not working

Hi everyone,  

I’m trying to back up an Oracle 19c database using the Deduplication Direct for Oracle plug-in, but I can’t get it to work.  

- I followed the documentation step by step and also did extensive troubleshooting with RMAN, but nothing has helped.  
- It looks like RMAN cannot load the Deduplication Direct library and fails to initialize the media manager library.  
- The error I get is: 

ORA-27211: unable to locate media manager library

- I enabled logging in the plug-in configuration, but no logs are being generated.  

Environment details:  
- NetBackup 10.2.1 on rhel 9 
- Oracle 19c (single node)  on rhel 7.9

Has anyone run into this issue before, or can suggest what I might be missing?

    I have never used the plug-in before, but :
    have you installed the agent?did you try agent based backup?did it worked?
    can you paste the configuration you have done here for co-pilot?
    is MSDP port open between your Linux and MSDP server (usually your media server)
