RHEL 6.2 x86_64 下安装Oracle 11g步骤,

在安装过程中如遇到问题可以一起讨论,,共同学习,如有错误,还请告知,谢谢

1.首先 修改 /etc/sysctl.conf文件 添加参数

[root@redz-server ~]# cat >>/etc/sysctl.conf

> #Oracle need parameters

> fs.aio-max-nr=1048576

> fs.file-max=6815744

> kernel.shmall=2097152

> kernel.shmmax=1024000000(根据系统内存多少来调整)

> kernel.shmmni=4096

> kernel.sem=250 32000 100 65500

> net.ipv4.ip_local_port_range=9000 65500

> net.core.rmen_default=262144

> net.core.rmem_max=4194304

> net.core.wmem_default=262144

> net.core.wmem_max=1048586

> EOF

 

执行  /sbin/sysctl -p使参数生效

 

2. 修改 /etc/security/limits.conf

[root@redz-server ~]# cat >>/etc/sysctl.conf

[root@redz-server ~]# cat >> /etc/security/limits.conf

> # oracle need parameters

> orcle  soft  nproc    2047

> oracle  hard  nproc   16384

> oracle  soft  nofile  1024

> oracle  hard  nofile  65536

> EOF

 

3. 修改 /etc/pam.d/limits.conf

[root@redz-server ~]# cat >> /etc/pam.d/login

> session  required  pam_limits.so

> EOF

4.修改 /etc/profile

if [ $USER = "oracle" ]; then

  if [ $SHELL = "/bin/ksh" ]; then

    ulimit -p 16384

    ulimit -n 65536

  else

    ulimit -u 16384 -n 65536

  fi

fi

4. 修改 /etc/csh.login

 vi /etc/csh.login

 

#oracle need setting

if ( $USER == "oralce" ) then

   limit maxproc        16384

   limit descriptors    65536

   umask 022

endif

 

5.创建用户组及用户

[root@redz-server ~]# /usr/sbin/groupadd oinstall

[root@redz-server ~]# /usr/sbin/groupadd dba

[root@redz-server ~]# /usr/sbin/useradd -m -g oinstall -G dba oracle

[root@redz-server ~]# echo "oracle"|passwd --stdin oracle

 

更改用户 oracle 的密码 。

passwd: 所有的身份验证令牌已经成功更新。

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

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),
