处理方法有下面两种，随便一种都可以

1.       主库的tns中关于备库配置，增加(UR=A)

2.       备库增加静态监听

如原来是

LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.30.166)(PORT = 1521))

    )

  )

ADR_BASE_LISTENER = /wfdb/db

现在如下，增加红色标记部分

LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.30.166)(PORT = 1521))

    )

  )

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (ORACLE_HOME= /wfdb/db/product/11.2.0/dbhome_1)

      (SID_NAME = WF)

    )

  )

ADR_BASE_LISTENER = /wfdb/db
