would like to know if it is possible to alter the unique member of all the three groups from 100 MB to 10 MB, and how. When I try to resize a logfile, I get the following error message:
SQL> alter database datafile '/edcsns20/oradata11/gasb/redo01.log' resize 50m; alter database datafile '/edcsns20/oradata11/gasb/redo01.log' resize 50m * ERROR at line 1: ORA-01516: nonexistent log file, datafile, or tempfile "/edcsns20/oradata11/gasb/redo01.log"
So the easiest way would be to add new redo log groups, with the file sizes you want. Then, issue the ALTER SYSTEM SWITCH LOGFILE command to start using one of the new groups. Then drop the old groups. You can do this with the database up and running.
