RMAN leaves database in mount state

Question

Hi,
Since recently we are experiencing situation where RMAN leaves the database in mount state and manual open is necessary. I don't recall it happened before...
(Linux RH ES3; 10gR2).
Recovery Manager: Release 10.2.0.2.0 - Production on Sun May 27 14:55:48 2007
Copyright (c) 1982, 2005, Oracle. All rights reserved.
connected to target database: TEST (DBID=1825238, not open) using target database control file instead of recovery catalog
RMAN> report obsolete;
2> delete force obsolete;
3> list backup;
4> sql 'ALTER DATABASE OPEN';
5> sql 'ALTER DATABASE BACKUP CONTROLFILE TO TRACE';
6> exit;
RMAN retention policy will be applied to the command RMAN retention policy is set to redundancy 1 Report of obsolete backups and copies
The same scenario(scripts) work on other databases with no problems.
Any suggestions are appreciated.
Thank you,
Dobby
