前段时间写了一篇关于oracle安装的博客,请参考linux ubuntu oracle 成功安装过程(图文),安装好以后,我登录企业后台(http://ubuntu:1158/em)报错,用sqlplus连接oracle也报错。

一,遇到的错误如下

1,ORA-12505: TNS:listener does not currently know of SID given in connect descriptor (DBD ERROR: OCIServerAttach)

2,ORA-28547: connection to server failed, probable Oracle Net admin error (DBD ERROR: OCISessionBegin)

3,sqlplus: error while loading shared libraries: libsqlplus.so: cannot open shared object file: No such file or directory

二,解决方法如下

解决问题一,ORA-12505: TNS:listener does not currently know of SID given in connect descriptor (DBD ERROR: OCIServerAttach)

1,找到tnsname.ora,listerner.ora的位置

root@ubuntu:/opt/ora10/network/admin# ls

listener.ora samples shrept.lst sqlnet.ora tnsnames.ora

2,修改listerner.ora配置

将(SID_NAME = PLSExtProc)改成(SID_NAME = ora1),SID_NAME在oracle管理后台http://ubuntu:1158/em中可以看到

解决问题二,ORA-28547: connection to server failed, probable Oracle Net admin error (DBD ERROR: OCISessionBegin)

问题一解决完后,就冒出这个问题,我在网上查了一下,千篇一律说这样解决,其实根本没有用。

1. 修改oracle的网络配置文件,具体做法是:在oracle安装目录下搜索sqlnet.ora文件,一般在$NETWORKADMIN目录下,

用记事本打开把文件中的一行:

SQLNET_AUTHENTICATION_SERVICES= (NTS)

修改为:

SQLNET_AUTHENTICATION_SERVICES= (NONE)

我发现我的sqlnet.ora根本没有这项目设置,我的sqlnet.ora里面只有一句是NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

2. 同时修改监听器配置文件,具体做法是: 在oracle安装目录下搜索listener.ora文件,一般在$NETWORKADMIN目录下,把主机名用ip地址代替,例如(ADDRESS = (PROTOCOL = TCP)(HOST = HBONLINE1)(PORT = 1523))改为(ADDRESS = (PROTOCOL = TCP)(HOST = 168.168.168.42)(PORT = 1523))

关于这种点,我更是不明白了,为什么换成ip,HOST后面对应的值,在/etc/hosts里面有映射,没必要换成ip.

根本原因是oracle服务根本没起来,可以通过ps -e |grep -i oracle来查看一下。启动起来就不会有这个问题了。

SQL> startup

ORACLE instance started.

解决问题三,sqlplus: error while loading shared libraries: libsqlplus.so: cannot open shared object file: No such file or directory

当我用zhangying@ubuntu:~$ sqlplus / as sysdba去登录时,提示上面的错误,解决方法如下

chmod -R a+rX /opt/ora10/

这里/opt/ora10是的我$ORACLE_HOME目录,加上后可以进去了。

三,我的配置文件

1,tnsnames.ora

ORA1 =
 (DESCRIPTION =
   (ADDRESS = (PROTOCOL = TCP)(HOST = ubuntu)(PORT = 1521))
   (CONNECT_DATA =
     (SERVER = DEDICATED)
     (SERVICE_NAME = ora1)
   )
 )

EXTPROC_CONNECTION_DATA =
 (DESCRIPTION =
   (ADDRESS_LIST =
     (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
   )
   (CONNECT_DATA =
     (SID = PLSExtProc)
     (PRESENTATION = RO)
   )
 )

2,listener.ora

SID_LIST_LISTENER =
 (SID_LIST =
   (SID_DESC =
     (SID_NAME = ora1)
     (ORACLE_HOME = /opt/ora10)
     (PROGRAM = extproc)
   )
 )

LISTENER =
 (DESCRIPTION_LIST =
   (DESCRIPTION =
     (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
     (ADDRESS = (PROTOCOL = TCP)(HOST = ubuntu)(PORT = 1521))
   )
 )

3,sqlnet.ora

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
