Linux平台Oracle 11g单实例 安装部署配置 快速参考

1.重建主机的Oracle用户 组 统一规范 uid gid 以保证共享存储挂接或其他需求的权限规范

userdel -r oracle
groupadd -g 500 oinstall
groupadd -g 501 dba
useradd -g oinstall -G dba -u 500 oracle

#id oracle
uid=500(oracle) gid=500(oinstall) 组=500(oinstall),501(dba)

2.安装好Oracle 需要的rpm包。安装rpm依赖包

rpm -q binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel glibc glibc-common glibc-devel gcc- gcc-c++ libaio-devel libaio libgcc libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-devel pdksh ksh

yum install binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel glibc glibc-common glibc-devel gcc- gcc-c++ libaio-devel libaio libgcc libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-devel pdksh ksh

注:pdksh没有安装,可以忽略。安装了ksh。

yum本地源配置参考:

3.修改配置文件 /etc/security/limits.conf

oracle              soft    nproc    2047
oracle              hard    nproc    16384
oracle              soft    nofile  1024
oracle              hard    nofile  65536
oracle              soft    stack    10240

4.修改配置文件 /etc/sysctl.conf

 

fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = XXXXXXXXXX //共享内存字节数(一般75%物理内存)
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586

 

注:重启主机或者输入命令 sysctl -p 生效当前配置

5.Oracle用户环境变量配置

 

export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1
export ORACLE_SID=jingyu
export NLS_LANG="american_america.ZHS16GBK"
export NLS_DATE_FORMAT="YYYY-MM-DD HH24:Mi:SS"
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export PATH=$ORACLE_HOME/bin:$PATH

 

6.解压oracle软件安装包

# unzip p10404530_112030_Linux-x86-64_1of7.zip; unzip p10404530_112030_Linux-x86-64_2of7.zip
# chown -R oracle:oinstall database

7.xmanager 安装数据库软件,dbca建库,netca创建监听

如果没有图形可采用静默模式安装~ 配置response配置文件即可。

8.根据实际需要调整数据库内存

9.调整数据库参数

打开数据库归档,规划归档路径,确定db_recovery_file_dest_size大小

--调整processes和open_cursors
alter system set processes = 1500 scope=spfile;
alter system set open_cursors = 1000;

system/sysaux表空间大小;

undo表空间大小 ;

temp表空间大小;

10.迁移win平台src用户的数据

创建表空间,用户,赋权

创建dblink

SQL> create public database link jingyu connect to src identified by src using 'src_db';

$impdp src/src network_link=jingyu schemas=src remap_tablespace=USERS:DBS_D_JINGYU parallel=2 logfile=src_jingyu.log

LONG 类型的 dblink 迁移报错信息:

ORA-31679: Table data object "SRC"."SRC_WF_FLOW" has long columns, and longs can not be loaded/unloaded using a network link

这种情况采用exp导出, imp导入 这些数据行即可。

11.rman备份策略制定

rman备份策略:手工做一个数据库的全备份,,定时每周日凌晨3点 0级备份  每周三凌晨3点 1级备份 每天凌晨4点备份归档 备份窗口为7天。

为提高1级备份效率,打开block_change_tracking

SQL> alter database enable block change tracking using file '/u01/app/oracle/oradata/jingyu/block_change_tracking.dbf';
SQL> select status from v$block_change_tracking;
--确定STATUS状态为ENABLED

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.
