11、迁移临时文件
The new tempfiles are created when you open the database.
12、修改快跟踪文件到ASM

14、迁移online log到ASM
根据官方文档提供的脚本 改写declare
cursor rlc is
select group# grp, thread# thr, bytes/1024 bytes_k from v$log order by 1;
stmt varchar2(2048);
swtstmt varchar2(1024) := 'alter system switch logfile';
ckpstmt varchar2(1024) := 'alter system checkpoint global';
begin
for rlcRec in rlc loop
stmt := 'alter database add logfile thread ' ||
rlcRec.thr || ' ''+LOG'' size ' ||
rlcRec.bytes_k || 'K';
execute immediate stmt;
begin
stmt := 'alter database drop logfile group ' || rlcRec.grp;
dbms_output.put_line(stmt);
execute immediate stmt;
exception
when others then
execute immediate swtstmt;
execute immediate ckpstmt;
execute immediate stmt;
end;
end loop;
end;

15、设置归档目录到ASM
15.1、备份归档
RMAN> BACKUP AS COPY ARCHIVELOG ALL DELETE INPUT;
15.2、修改归档目录
SYS@ prod>shutdown immediate;
SYS@ prod>startup nomount;
SYS@ prod>alter system set log_archive_dest_1='LOCATION=+ARCH';
SYS@ prod>alter database mount;
SYS@ prod>archive log list;
15.3、切日志组查看
SYS@ prod>alter system switch logfile;
SYS@ prod>alter system switch logfile;
SYS@ prod>alter system switch logfile;
SYS@ prod>alter system switch logfile;
16、db_create_file_dest参数修改
