两种RECOVER TABLESPACE 方法有何区别??
一个数据文件丢失,恢复:
1.
SQL>startup mount;
SQL> alter database datafile '/u03/DB1/vol01/users01.dbf' offline;
SQL> alter database open;
2.
now, restore the backup for '/u03/DB1/vol01/users01.dbf'
3.
SQL> alter database recover tablespace users;
alter database recover tablespace users
*

在STEP3中,如果不用上边方法,而用下面方法,则没问题:
If I use "recover tablespace XXX", is is no problem:
SQL> recover tablespace users;

SQL> alter database datafile '/u03/DB1/vol01/users01.dbf' online;
Database altered.

哪位解释一下两种RECOVER TABLESPACE 方法有何区别?为何" alter database recover tablespace users" 出错?
相应的解释为：
ALTER DATABASE [database]
{ MOUNT [STANDBY DATABASE] [EXCLUSIVE | PARALLEL]
| CONVERT
| OPEN [RESETLOGS | NORESETLOGS]
| ACTIVATE STANDBY DATABASE
| ARCHIVELOG
| NOARCHIVELOG
| RECOVER recover_clause
看来确实有这个语法...
知道了:
alter database recover tablespace XXXX 在MOUNT 下用,
recover tablespace XXXX 在OPEN 壮态用
