Oracle Dataguard报错：ARC1: Becoming the ‘no FAL’ ARC

共计 27041 个字符，预计需要花费 68 分钟才能阅读完成。

环境：RAC+ 单机 Dataguard
问题：启动 DG 备库到 mount 阶段，启动 MRP 进程后，发现后台日志不打印归档传输信息，另外备库日志打开 ARC1: Becoming the ‘no FAL’ ARC

1、启动 DG 备库到 mount 阶段，启动 MRP 进程后，发现后台日志不打印归档传输信息，
，发现备库中的日志有报错现象，报：ARC1: Becoming the ‘no FAL’ ARC 错误，告警中日志如下

2、在备库中查询查询状态如下，其中有后台日志报错信息

SQL> SELECT MESSAGE FROM V$DATAGUARD_STATUS;

MESSAGE

7 rows selected.

3、此时通过第 2 步是发现备库中有报归档日志错误信息，可以先到主库是查询是否报错
查询结果如下：
SQL> SELECT MESSAGE FROM V$DATAGUARD_STATUS;

MESSAGE

4、通过第三步发现主库中无法连接备库，导致报 12154 错误，通过分析，由于我们在备库中采集的是静态监听方式来同步数据，在服务器启动时，并不会自动启动静态监听，从而导致 RAC 和备库不是属于连接状态，

5、解决方法先在备库中手动启动静态监听，观察备库是否报错

6、此时再次查询 DG 的状态，发现有归档日志传输过到 DG 库中

8、通过日志发现 DG 库中是正常的，可以通过在主库中做日志切换观察备库中的日志是否打印，若能正常打印则是正常的
在主库中做日志切换：
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 115
Next log sequence to archive 117
Current log sequence 117

SQL> alter system switch logfile;
SQL> /

System altered.

SQL> /

SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 119
Next log sequence to archive 121
Current log sequence 121
SQL>

9、在备库中日志打印信息，可以判断归档日志是可以正常传输
