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)

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';
rman
[oracle@cxlrac01 ~]$ rman target /

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

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。
