PLSQL连接本地oracle或远程oracle数据库,实现随意切换
前言
每次安装Oracle以后,都会出现使用plsql连接不上的问题!多次重启电脑、重装系统的磨人经历之后,终于做出这么一篇文章,希望能帮助广大技术人员减少一些时间,顺利进行连接。
注:不安装oracle,可以用plsql连接远程数据库(只要有oracle的network文件夹就行)。
本文主要讲述如何连接本地oracle数据库或者远程oracle数据库,实现随意切换。
注:首先下载64位oracle以及32位轻量级客户端(注意版本的对应,我用的是11g的oracle和11.2的客户端):
以下步骤请自行更改路径,不然,出错了别怪我哦:
step1 复制network文件
安装步骤网上可以搜到!
oracle安装到某路径下,
客户端随便解压到一个路径,我的是放在D:appshuhaoinstantclient_11_2了。
然后把oracle中的D:appshuhaoproduct11.2.0dbhome_1里面的整个network文件夹复制,
粘贴到客户端文件夹D:appshuhaoinstantclient_11_2下面,如下图所示:

step2 修改配置文件
2.1 修改oracle数据库文件
D:appshuhaoproduct11.2.0dbhome_1NETWORKADMINlistener.ora文件内容,添加一个SID_DESC:
-
# listener.ora Network Configuration File: D:appshuhaoproduct11.2.0dbhome_1 etworkadminlistener.ora
-
# Generated by Oracle configuration tools.
-
-
SID_LIST_LISTENER =
-
(SID_LIST =
-
(SID_DESC =
-
(SID_NAME = CLRExtProc)
-
(ORACLE_HOME = D:appshuhaoproduct11.2.0dbhome_1)
-
(PROGRAM = extproc)
-
(ENVS = "EXTPROC_DLLS=ONLY:D:appshuhaoproduct11.2.0dbhome_1inoraclr11.dll")
-
)
-
#下面的SID_DESC是新增加的内容,注意修改ORACLE_HOME路径
-
(SID_DESC =
-
(SID_NAME = orcl)
-
(ORACLE_HOME = D:appshuhaoproduct11.2.0dbhome_1)
-
(GLOBAL_DBNAME = orcl)
-
)
-
)
-
-
LISTENER =
-
(DESCRIPTION_LIST =
-
(DESCRIPTION =
-
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
-
)
-
)
-
-
ADR_BASE_LISTENER = D:appshuhao
=================================分割线==================================
2.2 修改oracle数据库文件
D:appshuhaoproduct11.2.0dbhome_1NETWORKADMINtnsnames.ora文件内容,源文件没有做改动:
-
# tnsnames.ora Network Configuration File: D:appshuhaoproduct11.2.0dbhome_1 etworkadmin nsnames.ora
-
# Generated by Oracle configuration tools.
-
-
ORACLR_CONNECTION_DATA =
-
(DESCRIPTION =
-
(ADDRESS_LIST =
-
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
-
)
-
(CONNECT_DATA =
-
(SERVICE_NAME = orcl)
-
)
-
)
-
-
LISTENER_ORCL =
-
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
-
-
ORCL =
-
(DESCRIPTION =
-
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
-
(CONNECT_DATA =
-
(SERVER = DEDICATED)
-
(SERVICE_NAME = orcl)
-
)
-
)
=================================分割线==================================
2.3 修改客户端文件
D:appshuhaoinstantclient_11_2 etworkadmintnsnames.ora文件内容:
-
# tnsnames.ora Network Configuration File: D:appshuhaoproduct11.2.0dbhome_1 etworkadmin nsnames.ora
-
# Generated by Oracle configuration tools.
-
-
ORACLR_CONNECTION_DATA =
-
(DESCRIPTION =
-
(ADDRESS_LIST =
-
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
-
)
-
(CONNECT_DATA =
-
(SERVICE_NAME = orcl)
-
)
-
)
-
-
LISTENER_ORCL =
-
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
-
-
ORCL =
-
(DESCRIPTION =
-
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
-
(CONNECT_DATA =
-
(SERVER = DEDICATED)
-
(SERVICE_NAME = orcl)
-
)
-
)
-
#新增 @ 标识符,用于区分本地与远程oracle
-
ORCL@192.168.0.164 =
-
(DESCRIPTION =
-
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.164)(PORT = 1521))
-
(CONNECT_DATA =
-
(SERVER = DEDICATED)
-
(SERVICE_NAME = orcl)
-
)
-
)
step3 配置OCI
不登录plsql,直接按Cancel,进入后在Tools--->Preferences---->Connection中配置OCI为32位客户端的OCI
D:appshuhaoinstantclient_11_2oci.dll
step4 环境变量配置
添加前2个系统变量:
1. 变量名:TNS_ADMIN
变量值:D:appshuhaoinstantclient_11_2 etworkadmin
2. 变量名:NLS_LANG
变量值:SIMPLIFIED CHINESE_CHINA.ZHS16GBK
3. Path中配置加入:
D:appshuhaoproduct11.2.0dbhome_1BIN;D:appshuhaoinstantclient_11_2;
step5 重启电脑(有时候不需要重启)
启动oracle服务与监听,这个就不需要描述了。
step6:登录plsql!!!
当看到Database下拉框中有本地的ORCL以及远程的ORCL@192.168.0.164就算成功了!!!
