RMAN-08137: WARNING: archived log not deleted, needed for standby or upstream capture process
SOLUATION:
Cause: The archive logs seems that it is not yet applied in the standby database.
                        Select sequence# , applied from v$archived_log;
 
Action: Check the standby database and apply the logs manually and the start the deletion process.
              I can delete the archive logs by force using the below command.
 
      RMAN > delete noprompt force archivelog all;
 
But I don't want to delete the archives which are not applied in standby  so i'm changing the configuration
              
RMAN> show all;

Old configuration:
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
 
Change as Below:
RMAN> CONFIGURE ARCHIVELOG DELETION POLICY TO SHIPPED TO STANDBY;
 
new RMAN configuration parameters:
 
CONFIGURE ARCHIVELOG DELETION POLICY TO SHIPPED TO STANDBY;
 
new RMAN configuration parameters are successfully stored
 
RMAN-08591: WARNING: invalid archived log deletion policy


Now check the configuration
 
RMAN> show all;
 
CONFIGURE ARCHIVELOG DELETION POLICY TO SHIPPED TO STANDBY;
 
 
Now I am able to delete those archivelogs now.
 
 
RMAN> delete noprompt archivelog all;
 
RMAN> crosscheck archivelog all;
 
Once I deleted those logs, I changed the rman configuration by the default one.
 
 
RMAN> CONFIGURE ARCHIVELOG DELETION POLICY CLEAR;
RMAN> Show all;
