Thanks to all who replied. I got a lot of hints from
all.
The problem I had was because I was not separately
backuping up the control files. I was relying on the
control files backup included in the full database
backups. These control files do not have details about
the current backup. So when that control file is
restored, since it does not have a details about the
latest backup to disk(backup to disk was done for test
purpose, this database was beeing backed up to tape),
and since according to it the lastest backup was to
tape, it was looking for channel to go to tape and
finding none gave the 'no channel error'.
The remedy is to take backup of control files after
the backup regular backups (tested works fine). or
use recovery catalog and use auxliary connection
(still to test).
In 9i setting autobackup on does a separate backup of
the control file.
