无法在Linux Mint中连接到Oracle 11g XE Apex Web界面

linux-mint oracle11g oracle linux

我已经在Linux Mint 17.3系统上安装了Oracle数据库Express Edition 11g Release 2 for Linux x64。安装过程成功。我能够使用sqlplus连接到数据库,创建新用户,执行命令等。在安装期间配置数据库时,我使用了默认端口,即8080和1521。但我无法连接到APEX url,即localhost:8080/APEX/f?我的系统中p=4950。在过去的几个小时里,我一直在寻找解决方案,但找不到任何地方。

lsnrctl命令的输出如下:

我没有修改任何tnsname。ora或listener.ora。这些文件的内容如下: 侦听器.ora

# listener.ora Network Configuration File:

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/xe)
      (PROGRAM = extproc)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
      (ADDRESS = (PROTOCOL = TCP)(HOST = iamharish15-HP-15-Notebook-PC)(PORT = 1521))
    )
  )

DEFAULT_SERVICE_LISTENER = (XE)

tnsnames.ora公司

# tnsnames.ora Network Configuration File:

XE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = iamharish15-HP-15-Notebook-PC)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
    )
  )

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )

当我启动SQL命令行并使用connect to XE登录时,如下所示:

SQL> connect username/password@XE
ERROR:
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor

但通常从终端,如果我使用 sqlplus username/password 我连接成功。我想我必须得到 XE 和 XEXDB 服务可以运行,但到目前为止我还不能运行。这方面的任何帮助都将非常有用。提前谢谢。

经过几个小时的“搜索”和一些“狂欢”,我终于可以解决我的问题了。以下是我解决问题的方法:

alter system set local_listener = '(ADDRESS=(PROTOCOL=TCP)(HOST=iamharish15-HP-15-Notebook-PC)(PORT=1521))' scope = both;

步骤#1解决了XE和XEXDB服务未显示问题,之后我运行 lsnrctl status XE和XEXDB服务都出现了,我可以使用命令行SQL工具登录 username/password@XE 命令但APEX网络界面仍然不可用。

然后我更新了tnsnames。奥拉和听众。ora文件中包含XEXDB条目和带有Presentation=HTTP行的DESCRIPTION条目。

tnsnames.ora公司

# tnsnames.ora Network Configuration File:

XE =
  (DESCRIPTION =
    (ADDRESS_LIST = 
      (ADDRESS = (PROTOCOL = TCP)(HOST = iamharish15-HP-15-Notebook-PC)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
    )
  )

XEXDB =
  (DESCRIPTION =
    (ADDRESS_LIST = 
      (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 8080))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XEXDB)
    )
  )

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )

侦听器.ora

# listener.ora Network Configuration File:

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/xe)
      (PROGRAM = extproc)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
      (ADDRESS = (PROTOCOL = TCP)(HOST = iamharish15-HP-15-Notebook-PC)(PORT = 1521))
    )
    (DESCRIPTION = 
      (ADDRESS = (PROTOCOL = tcp)(HOST = 127.0.0.1)(PORT = 8080))(Presentation = HTTP)(Session = RAW)
    )
  )

DEFAULT_SERVICE_LISTENER = (XE)

之后,我使用以下命令重新加载了它们的值:

/etc/init.d/oracle-xe force-reload

这解决了这个问题,我可以连接到APEX网页界面并创建新的工作区、用户等。
