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。

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.

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

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),
