前言

在使用 AnyBackup 管理控制台发起 Oracle RAC 数据库备份后，在任务历史记录 > 执行输出中显示如下错误信息：
control file backup failed; in Oracle RAC, target might not be on shared storage.
or
control file backup failed; in Oracle RAC, target is likely on a local file system .

RMAN输出报错,请检查下是否符合备份恢复条件、是否有配置错误或者有对Oracle的错误操作。 错误提供者:
oracleschedule，错误值:425984055，错误位置:ncOracleExecThread.cpp:877)

一、信息确认

共享目录位置

节点1

[oracle@cxlrac01 ~]$ rman target /

节点2

[oracle@cxlrac02 ~]$ rman target /

RMAN> exit


Recovery Manager complete.
[oracle@cxlrac02 ~]$ 

二、RAC修改snapshot controlfile 参数

在其中一节点下进行参数修改CONFIGURE SNAPSHOT CONTROLFILE NAME TO ‘+DATAC1/TDHLBG/snapcf_tdhlyl.f’;

[oracle@cxlrac01 ~]$ rman target /

Recovery Manager: Release 19.0.0.0.0 - Production on Tue Nov 28 14:46:48 2023
Version 19.15.0.0.0

connected to target database: TDHLYL (DBID=1578450313)

RMAN> 

RMAN> 

RMAN> show snapshot controlfile name;

using target database control file instead of recovery catalog
RMAN configuration parameters for database with db_unique_name TDHLYL are:
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u01/app/oracle/product/19.0.0.0/dbhome_1/dbs/snapcf_tdhlyl1.f'; # default

RMAN> 

RMAN> CONFIGURE SNAPSHOT CONTROLFILE NAME TO '+DATAC1/TDHLYL/snapcf_TDHLyl.f';

new RMAN configuration parameters:
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '+DATAC1/TDHLYL/snapcf_TDHLyl.f';
new RMAN configuration parameters are successfully stored

RMAN> show snapshot controlfile name;

RMAN configuration parameters for database with db_unique_name TDHLYL are:
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '+DATAC1/TDHLYL/snapcf_TDHLyl.f';

RMAN> 

RMAN> exit


Recovery Manager complete.
[oracle@cxlrac01 ~]$ 

在第二节点确认参数信息：

[oracle@cxlrac02 ~]$ 
[oracle@cxlrac02 ~]$ rman target /

Recovery Manager: Release 19.0.0.0.0 - Production on Tue Nov 28 14:48:29 2023

RMAN> 

RMAN> show snapshot controlfile name;

using target database control file instead of recovery catalog
RMAN configuration parameters for database with db_unique_name TDHLYL are:
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '+DATAC1/TDHLYL/snapcf_tdhlyl.f';

RMAN> exit


Recovery Manager complete.

三、字典表确认以及测试

select * from V$RMAN_CONFIGURATION;

在 AnyBackup 控制台重新发起备份任务进行测试。
