dg搭建后开库报错
SQL> alter database open;
alter database open
*
ERROR at line 1:
ORA-10458: standby database requires recovery
ORA-01152: file 1 was not restored from a sufficiently old backup
ORA-01110: data file 1: '/u01/app/oracle/oradata/standby/system.258.1170868637'
处理办法
1.主库检查通道状态，同步相关参数等
##主库
[oracle@racstd1 backup]$ sqlplus / as sysdba

如果第一次搭建dg数据量少的情况下，
2.建议对主库重新做备份
3.备库清理之前备份文件
[oracle@upg19dg onlinelog]$ cd /backup/
[oracle@upg19dg backup]$ ls
arch_STANDBY_20240613_13_1 arch_STANDBY_20240613_19_1 ctl_STANDBY_20240613_16_1 data_STANDBY_20240613_11_1 data_STANDBY_20240613_18_1
arch_STANDBY_20240613_14_1 arch_STANDBY_20240613_20_1 ctl_STANDBY_20240613_22_1 data_STANDBY_20240613_12_1 data_STANDBY_20240613_9_1

[oracle@upg19dg backup]$ rm -f *
4.主库重新向备库传备份
scp * oracle@192.168.213.116:/backup/
5.备库清理数据文件
[oracle@upg19dg oradata]$ cd standby/
[oracle@upg19dg standby]$ ls

-bash: cd: ..S: No such file or directory

o1_mf_2_m6o4jfwg_.log o1_mf_3_m6o4k07k_.log
[oracle@upg19dg onlinelog]$ rm -f *
5.备库手动重新恢复
[oracle@upg19dg onlinelog]$ rman target /
