一 前期过程:下载Oracle for linux (x86),上传至Linux
二,安装前准备:
1,硬件要求,测试只要5G左右的空安装目录空闲空间,内存512mb以上,cpu1.5ghz以上吧.
2,环境要求:检查包,最好机器能上网,也就直接更新以下包,
yum install gcc
yum install make
yum install setarch
yum install openmotif
yum install libgomp
yum install libXP
yum install glibc
基本有这些包就不会出错了
3,内核参数修改:
vi /etc/sysctl.conf
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default=262144
net.core.rmem_max=262144
net.core.wmem_default=262144
net.core.wmem_max=262144
对以上设置生效,/sbin/sysctl -p
vi /etc/security/limits.conf 加入以下内容
* soft nproc 2047
* hard nproc 16384
* soft nofile 1024
* hard nofile 65536
vi /etc/pam.d/login 在后面加入一行,注意对应
session required /lib/security/pam_limits.so
vi /etc/selinux/config --( 禁用SELINUX,,安装完后可再还原成原值 ) 将SELINUX设置为
SELINUX=disabled
4,添加用户和组
groupadd dba
useradd -g dba oracle
5,创建oracle安装文件夹,并设置相应权限,假设我要装在/export 这个挂载点下:
mkdir -p /export/oracle/product/10.2.0/db_1
chown -R oracle:dba /export/oracle
chmod 775 /export/oracle
6,设置环境变量
查看用户的shell ,
(1.查看当前使用的shell类型
# echo $SHELL
/usr/bin/bsh
2.改变test用户登陆的默认shell
$ chsh test /usr/bin/ksh 重新登陆后生效 或者使用root用户直接修改/etc/passwd文件
将test:!:1002:1001::/home/test:/usr/bin/bsh修改为
test:!:1002:1001::/home/test:/usr/bin/ksh
3.如果系统没有提供用户想使用的shell类型,那么用户需要自己下载对应的shell并安装,并将该shell加入到如下配置文件中,使之成为系统可用的
shell/etc/shells/etc/security/login.cfg )
确定后根据oracle 用户的默认shell,对默认 shell start-up文件作如下改变,如果是Bourne, Bash, or Korn shell,修改环境变量/etc/profile文件如下:
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
如果是c shell,则环境变量文件 /etc/csh.login的修改值如下:
if ( $USER == "oracle" ) then
limit maxproc 16384
limit descriptors 65536
end if

To query the Oracle tablespace size, follow the following steps: Determine the tablespace name by running the query: SELECT tablespace_name FROM dba_tablespaces; Query the tablespace size by running the query: SELECT sum(bytes) AS total_size, sum(bytes_free) AS available_space, sum(bytes) - sum(bytes_free) AS used_space FROM dba_data_files WHERE tablespace_

Data import method: 1. Use the SQLLoader utility: prepare data files, create control files, and run SQLLoader; 2. Use the IMP/EXP tool: export data, import data. Tip: 1. Recommended SQL*Loader for big data sets; 2. The target table should exist and the column definition matches; 3. After importing, data integrity needs to be verified.

Uninstall method for Oracle installation failure: Close Oracle service, delete Oracle program files and registry keys, uninstall Oracle environment variables, and restart the computer. If the uninstall fails, you can uninstall manually using the Oracle Universal Uninstall Tool.

Oracle provides multiple deduplication query methods: The DISTINCT keyword returns a unique value for each column. The GROUP BY clause groups the results and returns a non-repetitive value for each group. The UNIQUE keyword is used to create an index containing only unique rows, and querying the index will automatically deduplicate. The ROW_NUMBER() function assigns unique numbers and filters out results that contain only line 1. The MIN() or MAX() function returns non-repetitive values of a numeric column. The INTERSECT operator returns the common values of the two result sets (no duplicates).

Oracle View Encryption allows you to encrypt data in the view, thereby enhancing the security of sensitive information. The steps include: 1) creating the master encryption key (MEk); 2) creating an encrypted view, specifying the view and MEk to be encrypted; 3) authorizing users to access the encrypted view. How encrypted views work: When a user querys for an encrypted view, Oracle uses MEk to decrypt data, ensuring that only authorized users can access readable data.

There are three ways to view instance names in Oracle: use the "sqlplus" and "select instance_name from v$instance;" commands on the command line. Use the "show instance_name;" command in SQL*Plus. Check environment variables (ORACLE_SID on Linux) through the operating system's Task Manager, Oracle Enterprise Manager, or through the operating system.

Creating an Oracle table involves the following steps: Use the CREATE TABLE syntax to specify table names, column names, data types, constraints, and default values. The table name should be concise and descriptive, and should not exceed 30 characters. The column name should be descriptive, and the data type specifies the data type stored in the column. The NOT NULL constraint ensures that null values are not allowed in the column, and the DEFAULT clause specifies the default values for the column. PRIMARY KEY Constraints to identify the unique record of the table. FOREIGN KEY constraint specifies that the column in the table refers to the primary key in another table. See the creation of the sample table students, which contains primary keys, unique constraints, and default values.

Oracle garbled problems can be solved by checking the database character set to ensure they match the data. Set the client character set to match the database. Convert data or modify column character sets to match database character sets. Use Unicode character sets and avoid multibyte character sets. Check that the language settings of the database and client are correct.
