In setting up RMAN on Oracle 8.1.6, I found it very convenient to have a backup controlfile. This is a good idea anyway. I added the following line to the backup script:

sql "alter database backup controlfile to ''$BACKUP_DIR/control_`date +%y%m%d`.ctl''";

This produces the following error:

RMAN-06162: sql statement: alter database backup controlfile to ''/rman3/fin7/control_030410.ctl''

RMAN-03023: executing command: sql
RMAN-03026: error recovery releasing channel resources

ORA-27086: skgfglk: unable to lock file - already in use Compaq Tru64 UNIX Error: 77: No locks available Additional information: 8

RMAN> Recovery Manager complete.

It actually produces the requested control file, but in the one time I've been able to test it, the file was corrupted. Any suggestions?
