1.修改系统参数: 在/etc/sysctl.conf 中添加如下内容 fs.aio-max-nr = 1048576fs.file-max = 6815744kernel.shmall = 2097152kernel.shmmax = 536870912kernel.shmmni = 4096kernel.sem = 250 32000 100 128net.ipv4.ip_local_port_range = 9000 65500net.co

1. 修改系统参数: 在 /etc/sysctl.conf 中添加如下内容

fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
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
使更改立即生效:
#sysctl -p

2. 创建oracle组和用户

#groupadd oinstall
#groupadd dba
#groupadd oper
#useradd -g oinstall -G dba,oper oracle11
#passwd oracle11

3. 设置oracle用户的shell limit
oracle11           hard    nproc   16384
oracle11           soft    nofile  1024
oracle11           hard    nofile  65536

4. 运行 "runInstaller" 进行安装

    其中有一步会检查系统是否缺少依赖组件,若缺少,用红帽安装光盘安装相应rpm包即可

    若系统没有设置交换分区,也会提示错误,忽略这个错误

    其他的按照提示一步步操作即可,直到安装成功


5. 设置环境变量

     安装成功后,$ORACLE_HOME, $ORACLE_SID这些环境变量并没有添加,为了使用方便,手动添加下

     打开 "~/.bashrc",设置如下环境变量

export ORACLE_HOME=/home/oracle11/app/oracle11/product/11.2.0/dbhome_1
export ORACLE_SID=orcl

export PATH=$PATH:$ORACLE_HOME/bin

6. 开启启动数据库

    1)  编辑 /etc/oratab,将最后一个参数"N"设为"Y"         

orcl:/home/oracle11/app/oracle11/product/11.2.0/dbhome_1:Y
    2)  编写启动脚本 "/etc/init.d/oracle11", 内容如下
#!/bin/sh

#chkconfig: 2345 99 01
#description: ORACLE 11g Server

ORACLE_HOME=/home/oracle11/app/oracle11/product/11.2.0/dbhome_1

if [ ! -f $ORACLE_HOME/bin/dbstart ]; then
  echo "ORACLE cannot start"
  exit
fi

case "$1" in
'start')
     echo "Starting Oracle11 Database..."
     su - oracle11 -c "$ORACLE_HOME/bin/dbstart"
     su - oracle11 -c "$ORACLE_HOME/bin/emctl start dbconsole"
     ;;

'stop')
     echo "Stoping Oracle Database"
     su - oracle11 -c "$ORACLE_HOME/bin/emctl stop dbconsole"
     su - oracle11 -c "$ORACLE_HOME/bin/dbshut"
     ;;

esac
    3) 增加可执行权限
chmod 777 /etc/init.d/oracle11

    4) 开机执行脚本
chkconfig -add oracle11

MySQL BLOB: how to optimize BLOBs requestsMySQL BLOB: how to optimize BLOBs requestsMay 13, 2025 am 12:03 AM

Optimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.

MySQL: String Data Types and Indexing: Best PracticesMySQL: String Data Types and Indexing: Best PracticesMay 12, 2025 am 12:11 AM

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
