'/oracle/PRD/sapdata2/sr3_151/sr3.data152'"
解决方案：

1.在linux 下切换到oracle账号

su - oraprd

2.运行sqlplus

sqlplus / as sysdba

3.运行查询数据文件查询语句

select name from v$datafile;

4.切换到root账号，运行dbv，校验所有的数据文件。

例如：
dbv file=/oracle/PRD/sapdata2/sr3_112/sr3.data113 blocksize=8192
dbv file=/oracle/PRD/sapdata2/sr3_113/sr3.data114 blocksize=8192
dbv file=/oracle/PRD/sapdata2/sr3_114/sr3.data115 blocksize=8192
dbv file=/oracle/PRD/sapdata2/sr3_115/sr3.data116 blocksize=8192
dbv file=/oracle/PRD/sapdata2/sr3_116/sr3.data117 blocksize=8192
dbv file=/oracle/PRD/sapdata2/sr3_117/sr3.data118 blocksize=8192
dbv file=/oracle/PRD/sapdata2/sr3_118/sr3.data119 blocksize=8192
dbv file=/oracle/PRD/sapdata2/sr3_119/sr3.data120 blocksize=8192
dbv file=/oracle/PRD/sapdata2/sr3_120/sr3.data121 blocksize=8192
dbv file=/oracle/PRD/sapdata2/sr3_121/sr3.data122 blocksize=8192
dbv file=/oracle/PRD/sapdata2/sr3_122/sr3.data123 blocksize=8192
dbv file=/oracle/PRD/sapdata2/sr3_123/sr3.data124 blocksize=8192
dbv file=/oracle/PRD/sapdata2/sr3_124/sr3.data125 blocksize=8192

5.再次切换到oracle账号，运行sqlplus

su - oraprd
sqlplus / as sysdba

6.运行SELECT * FROM V$DATABASE_BLOCK_CORRUPTION;

此语句会查询到所有的坏块文件

7.切换到RMAN运行修复命令（官方给的修复命令：RECOVER CORRUPTION LIST;）

RMAN> run{
2> ALLOCATE CHANNEL ch0 TYPE 'SBT_TAPE';
3> blockrecover corruption list;
4> release channel ch0;
5> }
显示如下：
released channel: ORA_DISK_1
allocated channel: ch0
channel ch0: SID=604 device type=SBT_TAPE
channel ch0: Symantec/BackupExec/1.1.0

Starting recover at 07-MAR-18

starting media recovery
media recovery complete, elapsed time: 00:07:35

Finished recover at 07-MAR-18

released channel: ch0

RMAN>
此方案完结

能用但是不能根除问题的方案如下：

RMAN> run{
ALLOCATE CHANNEL ch0 TYPE 'SBT_TAPE';
SEND 'BSA_SERVICE_HOST=BE2015,NBBSA_TOTAL_STREAMS=1,NBBSA_JOB_COOKIE={C0C0EF66-87CE-43F3-9E09-5786605E09CC},NBBSA_DB_DEVICE_NAME=Oracle-Linux::\bvprddb.byvin.com\PRD';
restore datafile 197,198;
release channel ch0;
}2> 3> 4> 5> 6>

using target database control file instead of recovery catalog
allocated channel: ch0
channel ch0: SID=625 device type=SBT_TAPE
channel ch0: Symantec/BackupExec/1.1.0

sent command to channel: ch0

Starting restore at 02-MAR-18
