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已經不支持)。是基於三層結構設計的。其client、middle、server可以位於同一台機器上也可以位於不同的機器。iSqlPlus不需要單獨安裝，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進行數據操作與數據庫管理。普通的數據庫用戶可以直接通過isqlplus的網址http://ip:port/isqlplus登陸,進入該網址后會直接進入數據庫用戶登陸界面，使用數據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，然后輸入網址http://ip:port/isqlplus/dba，進入該網址后首先會彈出一個登陸框，要求先輸入iSQL*Plus DBA的用戶和密碼，注意這里不是數據庫用戶，而是iSQL*PLUS應用服務器要求的用戶和密碼，然后才能出現iSQL*PLUS登陸界面，此時可以輸入sys或者system用戶，登陸數據庫進行管理。要以DBA身份登陸isqlplus，必須先配置好oc4j用戶。采用xml配置文件認證的方式。該配置文件位於$ORACLE_HOME/oc4j/j2ee/isqlplus/application-deployments/isqlplus/config但是該配置文件中的密碼是加密過的，所以我們不能手動修改該文件，而是通過JAZN(Java AuthoriZatioN)來配置。JAZN是ORACLE提供的一個JASS(Java Authentication and Authorization Service)工具.
如何進入JAZN命令環境？
1.進入到目錄$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，位於$ORACLE_HOME/jdk
3.執行以下命令
[oracle@DB-Server isqlplus]$ $ORACLE_HOME/jdk/bin/java -Djava.security.properties=$ORACLE_HOME/oc4j/j2ee/home/config/jazn.security.props -jar $ORACLE_HOME/oc4j/j2ee/home/jazn.jar -user "iSQL*Plus DBA/admin" -password welcome -shell
其中realm=iSQL*Plus DBA，user=admin，這些可以從xml配置文件中看到，admin的默認密碼是welcome，但是admin用戶默認沒有webDba權限，不能直接用於登陸isqlplus。通過JAZN，可以完成以下任務
1:新建用戶kerry 密碼設置為etl123!@#
JAZN:> adduser "iSQL*Plus DBA" kerry etl123!@#
2:列出用戶
查看這個組的用戶
JAZN:> listusers "iSQL*Plus DBA"
admin
kerry
JAZN:> listusers
iSQL*Plus DBA/admin
iSQL*Plus DBA/kerry
3.授予用戶kerry DBA的權限
JAZN:> grantrole webDba "iSQL*Plus DBA" kerry
4.撤銷用戶kerry DBA的權限
JAZN:> revokerole webDba "iSQL*Plus DBA" kerry
5.查看角色
JAZN:> listroles
iSQL*Plus DBA/webDba
iSQL*Plus DBA/admin
6.刪除用戶
JAZN:> remuser "iSQL*Plus DBA" kerry
7.修改用戶密碼
JAZN:> setpasswd "iSQL*Plus DBA" kerry etl123!@# 123456
8.退出JAZN命令環境
JAZN:> exit
上面我們創建了一個用戶kerry，密碼為etl123!@#，並且已經授予webDba權限。接下來重新啟動isqlplus應用服務器isqlplusctl stop、isqlplusctl start
再進入網址http://ip:5560/isqlplus/dba，在彈出的對話框中輸入kerry和etl123!@#，就可以進入到數據庫登陸界面了，選擇以sysdba或sysoper身份登陸了。
啟動iSQL*PLUS
如果登錄isqlplus頁面打不開（報錯）： http://ip:5560/isqlplus/，首先檢查isqlplus服務啟動沒有，然后檢查一下端口
[oracle@DB-Server ~]$ isqlplusctl start

配置問題
1：變更session的有效期：
在$ORACLE_HOME/oc4j/j2ee/oc4j_applications/applications/isqlplus/isqlplus/WEB-INF下的web.xml文件中。
設置：
<session-config>
<session-timeout>15</session-timeout>
</session-config>
為分鍾狀態。
2：限制登錄
[oracle@DB-Server WEB-INF]$ vi web.xml
