oracle alter database,alter database ... create datafile的原理及用途
某生产库standby报警out of sync，版本10204;
登陆standby，尝试开启恢复进程，alertlog信息如下
ALTER DATABASE RECOVER managed standby database disconnect from session

Errors in file /test/d01/app/oracle/admin/intelp/bdump/intelp_mrp0_77.trc:
ORA-01111: Message 1111 not found; No message file for product=RDBMS, facility=ORA; arguments: [49]
ORA-01110: Message 1110 not found; No message file for product=RDBMS, facility=ORA; arguments: [49] [/test/d01/app/oracle/product/10.2.0/db_1/dbs/UNNAMED00049]
SQL> select file#,name from v$datafile order by 2;
FILE# NAME
---------- --------------------------------------------------
49 /test/d01/app/oracle/product/10.2.0/db_1/dbs/UNNAMED00049
primay该文件路径为/test/d02/oradata/intelp，而standby该文件系统已经占满，所以才会创建失败
解决方法
SQL> select status,file#,name from v$datafile where status=’RECOVER’;
RECOVER 47 /test/d02/oradata/intelp/vaultlob27.dbf
RECOVER 48 /test/d02/oradata/intelp/vaultlob28.dbf
RECOVER 49 /test/d06/oradata/intelp/vaultlob29.dbf
RECOVER 50 /test/d01/app/oracle/product/10.2.0/db_1/dbs/UNNAMED00050
SQL> alter system set standby_file_management=manual;
System altered.
SQL> alter database create datafile '/test/d01/app/oracle/product/10.2.0/db_1/dbs/UNNAMED00049' as '/test/d06/oradata/intelp/vaultlob29.dbf';
Database altered
SQL> alter database create datafile '/test/d01/app/oracle/product/10.2.0/db_1/dbs/UNNAMED00050' as '/test/d06/oradata/intelp/vaultlob30.dbf';
Database altered.
SQL> select status,file#,name from v$datafile where status=’RECOVER’;
RECOVER 47 /test/d02/oradata/intelp/vaultlob27.dbf
RECOVER 48 /test/d02/oradata/intelp/vaultlob28.dbf
RECOVER 49 /test/d06/oradata/intelp/vaultlob29.dbf
RECOVER 50 /test/d06/oradata/intelp/vaultlob30.dbf
由于/test/d02以满，故将datafile 48迁移至其他文件系统
SQL> alter database create datafile '/test/d02/oradata/intelp/vaultlob28.dbf' as '/test/d06/oradata/intelp/vaultlob28.dbf';
Database altered.
$ rm vaultlob28.dbf
SQL> alter system set standby_file_management=auto;
System altered
此刻重启备库恢复进程，问题得到解决
小结
alter database … create datafile的作用
Creates a new empty datafile in place of an old one--useful to re-create a datafile that was lost with no backup.
前提是db开启归档模式且自愿数据文件创建以来的archive log都可用.
该命令通过查看control file提取出创建文件的DDL命令，初始化创建该文件(此刻文件内容为空)，然后利用archive log重做所有的redo.
可在没有数据文件备份时使用。
