Oracle’s default port is 1521, other ports include: 1522 (Oracle Net Listener), 8080 (APEX), 1158 (Database Vault) and 2483 (TDE). To change the default port, edit the LISTENER.ORA file, change the port number from 1521 to the preferred port, and restart the listener.
Oracle Default Port
Oracle is a popular relational database management system (RDBMS). Each Oracle instance has a port number that is used to communicate with client and server processes.
Default port
The default port of Oracle database is 1521. This is the default port for all versions in the Oracle product family.
Other Ports
In addition to the default port, Oracle uses other ports to perform specific tasks:
- 1522: Oracle Net Listener port, used to listen for client connection requests.
- 8080: Oracle Application Express (APEX) port, used to access APEX web applications.
- 1158: Oracle Database Vault port, used to access Database Vault functionality.
- 2483: Oracle Transparent Data Encryption (TDE) port, used to encrypt and decrypt data.
Changing the Default Port
For security or other reasons, you may need to change the port that Oracle is using. The following steps outline how to make changes:
- Edit the
LISTENER.ORA
file. - Find the following line:
(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521)))
- Change the port number from 1521 Change to your preferred port.
- Restart the listener.
Note:
- Please shut down all Oracle services before changing the port.
- Make sure to update the firewall rules to allow communication through the new port.
- Other client applications may need to update their configuration accordingly to connect to the new port.

oracle asm指的是“自动存储管理”,是一种卷管理器,可自动管理磁盘组并提供有效的数据冗余功能;它是做为单独的Oracle实例实施和部署。asm的优势:1、配置简单、可最大化推动数据库合并的存储资源利用;2、支持BIGFILE文件等。

方法:1、利用“select*from user_indexes where table_name=表名”语句查询表中索引;2、利用“select*from all_indexes where table_name=表名”语句查询所有索引。

在oracle中,可以利用“TO_SINGLE_BYTE(String)”将全角转换为半角;“TO_SINGLE_BYTE”函数可以将参数中所有多字节字符都替换为等价的单字节字符,只有当数据库字符集同时包含多字节和单字节字符的时候有效。

在Oracle中,可利用lsnrctl命令查询端口号,该命令是Oracle的监听命令;在启动、关闭或重启oracle监听器之前可使用该命令检查oracle监听器的状态,语法为“lsnrctl status”,结果PORT后的内容就是端口号。

在oracle中,可以利用“drop sequence sequence名”来删除sequence;sequence是自动增加数字序列的意思,也就是序列号,序列号自动增加不能重置,因此需要利用drop sequence语句来删除序列。

在oracle中,可以利用“select ... From all_tab_columns where table_name=upper('表名') AND owner=upper('数据库登录用户名');”语句查询数据库表的数据类型。

方法:1、利用“LOWER(字段值)”将字段转为小写,或者利用“UPPER(字段值)”将字段转为大写;2、利用“REGEXP_LIKE(字符串,正则表达式,'i')”,当参数设置为“i”时,说明进行匹配不区分大小写。

方法:1、利用“alter system set sessions=修改后的数值 scope=spfile”语句修改session参数;2、修改参数之后利用“shutdown immediate – startup”语句重启服务器即可生效。
