Is it possible to concat values in the rman command lines?
I am using the following statement to back up the database.

RMAN> run {
2> backup as compressed backupset database tag 'BACKUP_FULL_ORCL%';
3> backup archivelog all delete all input tag 'BACKUP_FULL_ARCHIVELOG%';
4> }

I would like to know how I do to concat a value like sysdate on the TAG.
For example:
backup as compressed backupset database tag 'BACKUP_FULL_ORCL'||sysdate
I tried and it is not worked.
