连接到Oracle XE Docker容器

如何解决连接到Oracle XE Docker容器

我无法通过Telnet或SQLPLUS从主机系统访问Oracle XE数据库Docker容器（版本2.3.0.4）：

这是我的Oracle XE和Container配置：

for j in range(3):
    p = multiprocessing.Process(target = functions_that_hangs,args = (arguments,))
    p.start()
    p.join(180)

    if p.is_alive: # used to check if process is still runing
        p.terminate()

    if p.exitcode >= 0 : # used to check if process completed successfully 
        break

Oracle配置：

docker port 54cb9336d8c3
1521/tcp -> 127.0.0.1:1521

lsnrctl输出：

cat /opt/oracle/product/18c/dbhomeXE/network/admin/listener.ora
DEFAULT_SERVICE_LISTENER = XE

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

cat /opt/oracle/product/18c/dbhomeXE/network/admin/tnsnames.ora
XE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
    )
  )

LISTENER_XE =
  (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))

我可以通过SQLPLUS从Docker容器访问XE数据库，但是无法从主机系统连接到DB。

Telnet到端口1521（在Docker容器中）

Telnet到端口1521（从macOS主机）

我是否错过了Oracle DB或Docker容器的配置？

解决方法

自从配置Oracle DB以来已经有一段时间了，但是在我看来，您已将侦听器设置为仅在回送接口上侦听。

您应该尝试以下配置：

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 0.0.0.0)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

为进行比较，这是来自Oracle数据库企业版官方Docker映像的listener.ora：

LISTENER =   (DESCRIPTION_LIST =     (DESCRIPTION =       (ADDRESS = (PROTOCOL = TCP)(HOST = 0.0.0.0)(PORT = 1521))       (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))     )   ) 
DIAG_ADR_ENABLED = off
SSL_VERSION = 1.0

和tnsnames.ora来自同一张图片：

ORCLCDB =   (DESCRIPTION =     (ADDRESS = (PROTOCOL = TCP)(HOST = 0.0.0.0)(PORT = 1521))     (CONNECT_DATA =       (SERVER = DEDICATED)       (SERVICE_NAME = ORCLCDB.localdomain)     )   ) 
ORCLPDB1 =   (DESCRIPTION =     (ADDRESS = (PROTOCOL = TCP)(HOST = 0.0.0.0)(PORT = 1521))     (CONNECT_DATA =       (SERVER = DEDICATED)       (SERVICE_NAME = ORCLPDB1.localdomain)     )   )
