Hi,
if you do not, so issue
allocate channel for delete type ''SBT_TAPE'';
before issueing
change backuppiece....delete
and after this
release channel;
If this doesn't help, my explanation for this is the following:
"change backuppiece ...delete" marks the Record in the Recovery-Catalog as
deleted but does not remove it.
And maybe you can do this several.
You can remove the Records with the SQL-Script below.
But no Guarantee - I'm not Oracle-Admin.

Rem DESCRIPTION
Rem Purges from RMAN Recovery Catalog the records marked as deleted
by
Rem the user.
Rem
Rem It is up to the user to mark the records as deleted using the
Rem RMAN command: CHANGE ... DELETE
Rem
Rem The Media Manager catalog is not updated by this script, only
Rem the recovery catalog
Rem
Rem Currently the records removed by this script might be
reinserted
Rem if a "resync from backup controlfile" is performed, this might
undo
Rem both the CHANGE...DELETE and the physical delete of the record.
Rem
Rem This script removes records from the following tables:
Rem AL
Rem RLH
Rem BP
Rem BS
Rem BCF
Rem BDF
Rem BCB
Rem BRL
Rem CCF
Rem CDF
Rem CCB

Rem NOTES
Rem To avoid using large amounts of rollback the script commits
Rem every 500 records by default
Rem This value can be changed by modyfing the following line
