log_archive_start参数在
10g中已经被抛弃,无意间给设置后:
SQL> show parameter log_archive_start;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
log_archive_start boolean FALSE
SQL> alter system set log_archive_start=true scope=spfile;
系统已更改。

Variable Size 130026528 bytes
Database Buffers 314572800 bytes
Redo Buffers 6406144 bytes
数据库装载完毕。
数据库已经打开。
每次启动都会出现这个提示信息:ORA-32004: obsolete and/or deprecated parameter(s) specified
采用这个方法修改后重启是无法消除的,因为数据库还是默认该参数被启用过:
alter system set log_archive_start=false scope=spfile;
SQL> show parameter log_archive_start
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
log_archive_start boolean FALSE
SQL> alter system reset log_archive_start scope=spfile;
alter system reset log_archive_start scope=spfile
*
第 1 行出现错误:
ORA-00905: 缺失关键字
SQL> alter system reset log_archive_start scope=spfile sid='*';
系统已更改。
SQL> shutdown immediate
数据库已经关闭。
已经卸载数据库。
ORACLE 例程已经关闭。
SQL> startup
ORACLE 例程已经启动。

那么,怎么查看那些参数被抛弃了呢:
SQL> set pagesize 2000
SQL> select name,description from v$parameter where isdeprecated='TRUE';
