iSQL*PLUS介绍

iSQL*PLUS是从ORACLE 9i开始提供的新功能,是SQL*PLUS的Web形式(ORACLE 11g已经不支持)。是基于三层结构设计的。其client、middle、server可以位于同一台机器上也可以位于不同的机器。iSqlPlus不需要单独安装,通过isqlplus,用户可以不需要安装任何ORACLE客户端,就能够通过浏览器方式的使用SQL*PLUS进行数据操作与数据库管理。普通的数据库用户可以直接通过isqlplus的网址http://ip:port/isqlplus登陆,进入该网址后会直接进入数据库用户登陆界面,使用数据库中的普通用户即可登陆;但如果是DBA用户登陆isqlpus,则需要首先配置iSQL*PLUS DBA的用户和口令,然后输入网址http://ip:port/isqlplus/dba,进入该网址后首先会弹出一个登陆框,要求先输入iSQL*Plus DBA的用户和密码,注意这里不是数据库用户,而是iSQL*PLUS应用服务器要求的用户和密码,然后才能出现iSQL*PLUS登陆界面,此时可以输入sys或者system用户,登陆数据库进行管理。要以DBA身份登陆isqlplus,必须先配置好oc4j用户。采用xml配置文件认证的方式。该配置文件位于$ORACLE_HOME/oc4j/j2ee/isqlplus/application-deployments/isqlplus/config但是该配置文件中的密码是加密过的,所以我们不能手动修改该文件,而是通过JAZN(Java AuthoriZatioN)来配置。JAZN是ORACLE提供的一个JASS(Java Authentication and Authorization Service)工具.

如何进入JAZN命令环境?

1.进入到目录$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.确保JAVA_HOME环境变量指向了正确的jdk(需要1.4以上)路径,可以使用ORACLE自带的jdk,位于$ORACLE_HOME/jdk

3.执行以下命令

[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,这些可以从xml配置文件中看到,admin的默认密码是welcome,但是admin用户默认没有webDba权限,不能直接用于登陆isqlplus。通过JAZN,可以完成以下任务

1:新建用户kerry 密码设置为etl123!@#

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

2:列出用户

查看这个组的用户

JAZN:> listusers "iSQL*Plus DBA"

admin

kerry

JAZN:> listusers

iSQL*Plus DBA/admin

iSQL*Plus DBA/kerry

3.授予用户kerry DBA的权限

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

4.撤销用户kerry DBA的权限

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

5.查看角色

JAZN:> listroles

iSQL*Plus DBA/webDba

iSQL*Plus DBA/admin

6.删除用户

JAZN:> remuser "iSQL*Plus DBA" kerry

7.修改用户密码

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

8.退出JAZN命令环境

JAZN:> exit

上面我们创建了一个用户kerry,密码为etl123!@#,并且已经授予webDba权限。接下来重新启动isqlplus应用服务器isqlplusctl stop、isqlplusctl start

再进入网址http://ip:5560/isqlplus/dba,在弹出的对话框中输入kerry和etl123!@#,就可以进入到数据库登陆界面了,选择以sysdba或sysoper身份登陆了。

启动iSQL*PLUS

如果登录isqlplus页面打不开(报错): http://ip:5560/isqlplus/,首先检查isqlplus服务启动没有,然后检查一下端口

[oracle@DB-Server ~]$ isqlplusctl start

日志信息

iSQL*PLUS使用的是Log4j,如下所示:

[oracle@DB-Server isqlplus]$ cd $ORACLE_HOME/oc4j/j2ee/oc4j_applications/applications/isqlplus/isqlplus/WEB-INF/classes

[oracle@DB-Server classes]$ ls

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

MySQL vs. Other Programming Languages: A ComparisonMySQL vs. Other Programming Languages: A ComparisonApr 19, 2025 am 12:22 AM

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages ​​such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages ​​have advantages in their respective fields such as data analytics, enterprise applications, and system programming.
