RFS[9]: Possible network disconnect with primary database

检查主备库remote_login_passwordfile参数,都是为EXCLUSIVE,确认没有问题

--备库
SQL> show parameter pass;

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
remote_login_passwordfile            string      EXCLUSIVE
SQL> select open_mode from v$database;

OPEN_MODE
--------------------
READ ONLY WITH APPLY

--主库
SQL> select database_role from v$database;

DATABASE_ROLE
----------------
PRIMARY

SQL> show parameter pass;

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
remote_login_passwordfile            string      EXCLUSIVE

检查主备库密码文件,证明主备库密码文件一致,也不是密码文件引起不同步

--主库
[oracle@oracle1 trace]$ cd $ORACLE_HOME/dbs
[oracle@oracle1 dbs]$ echo $ORACLE_SID
orcl
[oracle@oracle1 dbs]$ ls -ltr orapw*

--备库

[oracle@oracle2 dbs]$ echo $ORACLE_SID
orcl
[oracle@oracle2 dbs]$ ls -l orapw*

[oracle@oracle2 dbs]$ md5sum orapworcl 
d27c234b5131b4d2e13b1eeb4388f0eb  orapworcl

查看数据库有logon触发器

SQL> select owner,trigger_name from dba_triggers where triggering_event LIKE '%LOGON%';

OWNER                          TRIGGER_NAME
------------------------------ ------------------------------
DBTOOLS                        TRIGGER_LOGINLIMIT

根据Error 1017 / ORA-16191 In Standby Alertlog (Doc ID 2225190.1)中描述logon触发器可能导致dg传输日志失败.
