增加数据文件时遇

db_files integer 200
修改db_files
SQL> alter system set db_files=300 scope=spfile;
System altered.
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
重新启动
SQL> startup
ORACLE instance started.

原因是RAC的节点db_files 参数不一致
| 本帖最后由 secooler 于 2015-5-5 12:09 编辑 在其中一个节点的sqlplus 里只执行shutdown /startup，只是对改节点的instane起作用。 1. set parameter to 不同的Sid 2.用srvctl 重启数据库 增加数据文件时遇 ORA-00059: maximum number of DB_FILES exceeded 查看db_files SQL> show parameter db_files NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ db_files integer 200 查看MAXDATAFILES SQL> alter database backup controlfile to trace; Database altered.

分别在两个节点查看，DB_FILES已修改。
