oracle instant client安装 用于PL/SQL Dev
虚拟机里的Linux安装了Oracle，由于在Windows物理机要用到PL/SQL Developer连接到虚拟机里的Oracle，但是不想在物理机里在重新安装一下Oracle了（太大了，没地了=。=）。于是用到了Oracle Instant Client。好了废话不多说了。步骤如下：1、先在Linux里配置好监听。listener.ora 文件内容如下# listener.ora Network Configuration File: /u01/app/oracle/product/10.2.0/db_1/network/admin/listener.ora# Generated by Oracle configuration tools.SID_LIST_LISTENER =(SID_LIST =(SID_DESC =(SID_NAME = PLSExtProc)(ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)(PROGRAM = extproc))(SID_DESC =(GLOBAL_DBNAME = wiseman)(ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)(SID_NAME = wiseman)))LISTENER =(DESCRIPTION_LIST =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.99)(PORT = 1521)))(DESCRIPTION =(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))))
注：SID_name的大小写必须和Linux里的SID一样。我的是小写2、然后是Windows端的配置了，先把http://www.oracle.com/technetwork/topics/winsoft-085727.html下的instantclient-basic-nt-11.2.0.3.0.zip下载下来（我的是32位系统），然后解压到C:\Oracle\instantclient_11_2下，然后把tnsnames.ora复制到C:\Oracle\instantclient_11_2\network\admin下。内容如下：GGDB =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.0.99)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = WISEMAN)))3、最后设置PL/SQL Developer，工具-->首选项下改成如下图内容即可
现在重启一下PL/SQL Developer，再次登陆就行了。
补充：Instant Client 不自带SQL*Plus所以可以在刚才的页面下载它，instantclient-sqlplus-nt-11.2.0.3.0.zip。下载完后，在配置一下windows端的系统变量。NLS_lANG=SIMPLIFIED CHINESE_CHINA.ZHS16GBKTNS_ADMIN=C:\Oracle\instantclient_11_2Path=C:\Oracle\instantclient_11_2
现在就可以用 sqlplus system/oracle@GGDB 进行连接了。
