如果是oracle9i，还需要更改如下参数：

alter system set log_archive_start=true scope=spfile;
但是如果在10g中也更改这些参数，数据库重启时会有如下提示：
ORA-32004: obsolete and/or deprecated parameter(s) specified

alter system set log_archive_format='%t_%s.dbf' scope=spfile;
但是如果在10g中也更改这些参数，数据库会不能启动，如下提示：
ORA-32004: obsolete and/or deprecated parameter(s) specified
ORA-19905: log_archive_format must contain %s, %t and %r
