PLSQL連接本地oracle或遠(yuǎn)程oracle數(shù)據(jù)庫(kù)實(shí)現(xiàn)隨意切換功能
先贊后看，此生必賺！
每次安裝Oracle以后，都會(huì)出現(xiàn)使用plsql連接不上的問(wèn)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(kù)（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(jí)客戶端(注意版本的對(duì)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(yè)面 點(diǎn)擊進(jìn)入客戶端下載頁(yè)面
以下步驟請(qǐng)自行更改路徑，不然，出錯(cuò)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(jiǎn)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(kù)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(kù)文件
D:\app\shuhao\product\11.2.0\dbhome_1\NETWORK\ADMIN\tnsnames.ora文件內(nèi)容，源文件沒(méi)有做改動(dòng)：
# 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(shí)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(dòng)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ORCL@192.168.0.164就算成功了！??！
OK, GAME OVER !
