我在重新启动新的MySQL ODBC连接时无法使我的监听器重新启动时遇到问题。
我已经创建了一个MySQL ODBC连接器
[root@localhost:10:19 ~]# cat /home/oracle/.odbc.ini
[root@localhost:10:19 ~]# cat /etc/odbc.ini
[ODBC Data Sources]
mydb = MySQL ODBC 8.0 ANSI Driver
[mydb]
Driver = /usr/lib64/libmyodbc8a.so
DATABASE = mydb
DESCRIPTION = Liferay 7 database
PORT = 3306
SERVER = localhost
OPTION = 3
SOCKET =
[oracle@localhost:10:22 ~]$ cat $ORACLE_HOME/hs/admin/initmydb.ora
#
# HS init parameters
#
HS_FDS_CONNECT_INFO = mydb
HS_FDS_TRACE_LEVEL = 0
HS_FDS_SHAREABLE_NAME = /usr/lib64/libmyodbc8a.so
#
# ODBC specific environment variables
#
set ODBCINI=/home/oracle/.odbc.ini
set LD_LIBRARY_PATH=/usr/lib64
#
# Environment variables required for the non-Oracle system
#
set HOME=/home/oracle
[grid@localhost:10:25 ~]$ cat $ORACLE_HOME/network/admin/listener.ora

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON # line added by Agent
VALID_NODE_CHECKING_REGISTRATION_LISTENER=SUBNET # line added by Agent

(ENVS="LD_LIBRARY_PATH=/usr/lib64:/u01/app/oracle/product/12.1.0/oracle/lib")
)
当我停止/重新启动监听器时，此方法正常工作
[grid@localhost:13:28 ~]$ lsnrctl stop

此后，我可以远程连接到我的oracle模式，并查询“ mydb”数据库链接。
如果我重新启动服务器，则数据库链接将不再起作用。
lsnrctl status显示与mydb相同的信息
Service "mydb" has 1 instance(s).
Instance "mydb", status UNKNOWN, has 1 handler(s) for this service...
我试图延迟监听器服务，以为启动监听器时MySQL服务可能无法启动并运行。 STARTUP_WAIT_TIME_LISTENER = 120在listener.ora中，但没有任何改变。
我是否缺少一些配置属性来使其正常工作？
