Dear All,

I have two specific queries:

1) While changing from noarchivelog mode to archivelog mode , why it is
necessary to do "alter database open archivelog" even if log_archive_start
=true is set in the init.ora file.

2) During hot back when we give "alter tablespace <TSname> begin backup",
the header of datafiles are freezed, then where are transactions
associated with these datafiles are written?
