Instead, I tried CONNECT SYS/password AS SYSDBA, and this worked OK.

This gave the "ORA-03113: end-of-file on communication channel" error.

One of our sysprogs asked if it might have something to do with the
change from BST to GMT, but this seems unlikely since the problem only
manifested this morning (2nd November).

Any more ideas, please, Niall? (Or anybody!). I'm feeling thoroughly
