The first cause of this error message is the fact that RMAN is configured to backup to disk, you will need to configure RMAN to back-up to tape rather than disk in order to use LEO with RMAN. The second cause of this error is the syntax. Test media manager doesn't know anything about the 'leo://' syntax.

Change RMAN configuration to backup to tape and then run the backup command making sure you use the right syntax.

OR

you can temporarily change the backup channel in the command syntax as seen below using run;

run
{
allocate channel ch1 type 'sbt_tape';
backup tablespace users format='/xxxxxxx/xxxxx/rman/db_%s_%p.dat';
}

OR

If you insist on using the Oracle test media manager, you will have to change the file name. The directory name is specified in the BACKUP_DIR parameter so it shouldn't appear in the command.

run
{
allocate channel ch1 type 'sbt_tape' PARMS="SBT_LIBRARY=oracle.disksbt,ENV=(BACKUP_DIR=/xxxxxxx/xxxxx/rman)";
backup tablespace users format='db_%s_%p.dat';
}
