iSQL*PLUS介紹

iSQL*PLUS是從ORACLE 9i開始提供的新功能，是SQL*PLUS的Web形式(ORACLE 11g已經(jīng)不支持)。是基于三層結(jié)構(gòu)設(shè)計(jì)的。其client、middle、server可以位于同一臺機(jī)器上也可以位于不同的機(jī)器。iSqlPlus不需要單獨(dú)安裝，通過isqlplus，用戶可以不需要安裝任何ORACLE客戶端，就能夠通過瀏覽器方式的使用SQL*PLUS進(jìn)行數(shù)據(jù)操作與數(shù)據(jù)庫管理。普通的數(shù)據(jù)庫用戶可以直接通過isqlplus的網(wǎng)址http://ip:port/isqlplus登陸,進(jìn)入該網(wǎng)址后會直接進(jìn)入數(shù)據(jù)庫用戶登陸界面，使用數(shù)據(jù)庫中的普通用戶即可登陸；但如果是DBA用戶登陸isqlpus，則需要首先配置iSQL*PLUS DBA的用戶和口令，然后輸入網(wǎng)址http://ip:port/isqlplus/dba，進(jìn)入該網(wǎng)址后首先會彈出一個(gè)登陸框，要求先輸入iSQL*Plus DBA的用戶和密碼，注意這里不是數(shù)據(jù)庫用戶，而是iSQL*PLUS應(yīng)用服務(wù)器要求的用戶和密碼，然后才能出現(xiàn)iSQL*PLUS登陸界面，此時(shí)可以輸入sys或者system用戶，登陸數(shù)據(jù)庫進(jìn)行管理。要以DBA身份登陸isqlplus，必須先配置好oc4j用戶。采用xml配置文件認(rèn)證的方式。該配置文件位于$ORACLE_HOME/oc4j/j2ee/isqlplus/application-deployments/isqlplus/config但是該配置文件中的密碼是加密過的，所以我們不能手動修改該文件，而是通過JAZN(Java AuthoriZatioN)來配置。JAZN是ORACLE提供的一個(gè)JASS(Java Authentication and Authorization Service)工具.

如何進(jìn)入JAZN命令環(huán)境？

1.進(jìn)入到目錄$ORACLE_HOME/oc4j/j2ee/isqlplus/application-deployments/isqlplus/下，如下所示：

[oracle@DB-Server isqlplus]$ pwd

/database/product/dbhome_1/oc4j/j2ee/isqlplus/application-deployments/isqlplus

[oracle@DB-Server isqlplus]$ ls

application.log config isqlplus orion-application.xml

2.確保JAVA_HOME環(huán)境變量指向了正確的jdk（需要1.4以上）路徑，可以使用ORACLE自帶的jdk，位于$ORACLE_HOME/jdk

3.執(zhí)行以下命令

[oracle@DB-Server isqlplus]$ $ORACLE_HOME/jdk/bin/java -Djava.security.properties=$ORACLE_HOME/oc4j/j2ee/home/config/jazn.security.props -jar $ORACLE_HOME/oc4j/j2ee/home/jazn.jar -user "iSQL*Plus DBA/admin" -password welcome -shell

其中realm=iSQL*Plus DBA，user=admin，這些可以從xml配置文件中看到，admin的默認(rèn)密碼是welcome，但是admin用戶默認(rèn)沒有webDba權(quán)限，不能直接用于登陸isqlplus。通過JAZN，可以完成以下任務(wù)

1:新建用戶kerry 密碼設(shè)置為etl123!@#

JAZN:> adduser "iSQL*Plus DBA" kerry etl123!@#

2:列出用戶

查看這個(gè)組的用戶

JAZN:> listusers "iSQL*Plus DBA"

admin

kerry

JAZN:> listusers

iSQL*Plus DBA/admin

iSQL*Plus DBA/kerry

3.授予用戶kerry DBA的權(quán)限

JAZN:> grantrole webDba "iSQL*Plus DBA" kerry

4.撤銷用戶kerry DBA的權(quán)限

JAZN:> revokerole webDba "iSQL*Plus DBA" kerry

5.查看角色

JAZN:> listroles

iSQL*Plus DBA/webDba

iSQL*Plus DBA/admin

6.刪除用戶

JAZN:> remuser "iSQL*Plus DBA" kerry

7.修改用戶密碼

JAZN:> setpasswd "iSQL*Plus DBA" kerry etl123!@# 123456

8.退出JAZN命令環(huán)境

JAZN:> exit

上面我們創(chuàng)建了一個(gè)用戶kerry，密碼為etl123!@#，并且已經(jīng)授予webDba權(quán)限。接下來重新啟動isqlplus應(yīng)用服務(wù)器isqlplusctl stop、isqlplusctl start

再進(jìn)入網(wǎng)址http://ip:5560/isqlplus/dba，在彈出的對話框中輸入kerry和etl123!@#，就可以進(jìn)入到數(shù)據(jù)庫登陸界面了，選擇以sysdba或sysoper身份登陸了。

啟動iSQL*PLUS

如果登錄isqlplus頁面打不開（報(bào)錯(cuò)）： http://ip:5560/isqlplus/，首先檢查isqlplus服務(wù)啟動沒有，然后檢查一下端口

[oracle@DB-Server ~]$ isqlplusctl start

為分鐘狀態(tài)。

2：限制登錄
