修改归档文件路径

SQL> alter system set log_archive_dest_1='+DATA' scope=both;
alter system set log_archive_dest_1='+DATA' scope=both
*
ERROR at line 1:
ORA-32017: failure in updating SPFILE
ORA-16179: incremental changes to "log_archive_dest_1" not allowed with SPFILE

 

后察看了文档，是由于语法中的存在一些小的技巧。

alter system set log_archive_dest_1='location=d:oradata' scope=both;

在文件目标中加上 location的字样就可以了。不知 oracle中还存在多少这种技巧。
