我们在 Windows 服务器上运行我们的 oracle 实例，当配置 RMAN 进行备份时，我们在日志中看到以下错误，

错误详情：

channel ch1: starting piece 1 at 07-MAY-17
channel ch1: finished piece 1 at 07-MAY-17
piece handle=\\backup_share\FULL_db01_20170507.BAK tag=COMPLETE_BACKUP comment=NONE
channel ch1: backup set complete, elapsed time: 02:10:37
channel ch1: starting incremental level 0 datafile backup set
channel ch1: specifying datafile(s) in backup set
including current control file in backup set
including current SPFILE in backup set
channel ch1: starting piece 1 at 07-MAY-17
released channel: ch1
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of backup command on ch1 channel at 05/07/2017 23:10:45
ORA-19504: failed to create file "\\backup_share\FULL_db01_20170507.BAK"
ORA-27038: created file already exists
OSD-04010: <create> option specified, file already exists

RMAN 命令脚本：

run{ 
Allocate channel ch1 type disk format '\\backup_share\full_%d_%T.bak'; 
Backup incremental level=0 database tag='complete_backup'; 
Release channel ch1; 
Allocate channel t1 type disk format '\\backup_share\ctrl_%d_%T'; 
Backup current controlfile; 
Release channel t1; 
}

尝试进行增量备份时，我看到了相同类型的日志记录。有人可以帮我解决这个问题吗？

[oracle@orcluat ~]$ oerr ora 27038
27038, 00000, "created file already exists"
// *Cause:  trying to create a database file, but file by that name already
//          exists
// *Action: verify that name is correct, specify reuse if necessary

%dformat 指定数据库的名称，并%T指定公历中的年、月、日，格式如下：YYYYMMDD. 它也反映在您的备份文件名中，FULL_db01_20170507.BAK. 可能有同名的文件。

最好%U在指定系统生成的唯一文件名的文件名格式中使用。

格式规范
