前言
先贊后看，此生必賺！
每次安裝Oracle以后，都會出現(xiàn)使用plsql連接不上的問題！多次重啟電腦、重裝系統(tǒng)的磨人經(jīng)歷之后，
今天看到這篇文章算是你我之幸！希望能幫助廣大技術(shù)人員減少一些時(shí)間，順利進(jìn)行連接！
注：也可以用plsql連接遠(yuǎn)程數(shù)據(jù)庫（只要有oracle的network\admin\tnsnames.ora就行）。
首先下載64位oracle以及32位輕量級客戶端(注意版本的對應(yīng)，我用的是11g的oracle和11.2的客戶端)：
點(diǎn)擊進(jìn)入oracle下載頁面 點(diǎn)擊進(jìn)入客戶端下載頁面
以下步驟請自行更改路徑，不然，出錯了別怪我哦：
step1 復(fù)制network文件
oracle安裝到某路徑下，安裝步驟很簡單，網(wǎng)上可以搜到！
客戶端隨便解壓到一個(gè)路徑，我的是放在D:\app\shuhao\instantclient_11_2了。
然后把oracle中的D:\app\shuhao\product\11.2.0\dbhome_1里面的整個(gè)network文件夾復(fù)制，
粘貼到客戶端文件夾D:\app\shuhao\instantclient_11_2下面，如下圖所示：
step2 修改配置文件
2.1 修改oracle數(shù)據(jù)庫文件
D:\app\shuhao\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora文件內(nèi)容，添加一個(gè)SID_DESC：
- # listener.ora Network Configuration File: D:\app\shuhao\product\11.2.0\dbhome_1\network\admin\listener.ora
- # Generated by Oracle configuration tools.
- SID_LIST_LISTENER =
- (SID_LIST =
- (SID_DESC =
- (SID_NAME = CLRExtProc)
- (ORACLE_HOME = D:\app\shuhao\product\11.2.0\dbhome_1)
- (PROGRAM = extproc)
- (ENVS = "EXTPROC_DLLS=ONLY:D:\app\shuhao\product\11.2.0\dbhome_1\bin\oraclr11.dll")
- )
- #下面的SID_DESC是新增加的內(nèi)容，注意修改ORACLE_HOME路徑
- (SID_DESC =
- (SID_NAME = orcl)
- (ORACLE_HOME = D:\app\shuhao\product\11.2.0\dbhome_1)
- (GLOBAL_DBNAME = orcl)
- )
- )
- LISTENER =
- (DESCRIPTION_LIST =
- (DESCRIPTION =
- (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
- )
- )
- ADR_BASE_LISTENER = D:\app\shuhao
2.2 修改oracle數(shù)據(jù)庫文件
D:\app\shuhao\product\11.2.0\dbhome_1\NETWORK\ADMIN\tnsnames.ora文件內(nèi)容，源文件沒有做改動：
- # tnsnames.ora Network Configuration File: D:\app\shuhao\product\11.2.0\dbhome_1\network\admin\tnsnames.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)
- )
- )
2.3 修改客戶端文件
D:\app\shuhao\instantclient_11_2\network\admin\tnsnames.ora文件內(nèi)容:
- # tnsnames.ora Network Configuration File: D:\app\shuhao\product\11.2.0\dbhome_1\network\admin\tnsnames.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 @ 標(biāo)識符，用于區(qū)分本地與遠(yuǎn)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
不登錄plsql，直接按Cancel，進(jìn)入后在Tools--->Preferences---->Connection中配置OCI為32位客戶端的OCI
D:\app\shuhao\instantclient_11_2\oci.dll
step4 環(huán)境變量配置
添加前2個(gè)系統(tǒng)變量：
1. 變量名：TNS_ADMIN
變量值：D:\app\shuhao\instantclient_11_2\network\admin
2. 變量名：NLS_LANG
變量值：SIMPLIFIED CHINESE_CHINA.ZHS16GBK
3. Path中配置加入：
D:\app\shuhao\product\11.2.0\dbhome_1\BIN;D:\app\shuhao\instantclient_11_2;
step5 重啟電腦（有時(shí)候不需要重啟）
啟動oracle服務(wù)與監(jiān)聽，這個(gè)就不需要描述了。
step6 登錄plsql！！！
當(dāng)看到Database下拉框中有本地的ORCL以及遠(yuǎn)程的[email protected]就算成功了！！！
OK, GAME OVER !
到此這篇關(guān)于PLSQL連接本地oracle或遠(yuǎn)程oracle數(shù)據(jù)庫實(shí)現(xiàn)隨意切換功能的文章就介紹到這了,更多相關(guān)PLSQL連接本地遠(yuǎn)程oracle內(nèi)容請搜索服務(wù)器之家以前的文章或繼續(xù)瀏覽下面的相關(guān)文章希望大家以后多多支持服務(wù)器之家！
