在RedHat企业版5.8上安装Oracle 10g 笔记

Jun 07, 2016 pm 05:14 PM

在RedHat企业版5.8上安装Oracle 10g 笔记,注意:在redhat 企业版5首行写上ldquo;127.0.0.1 主机名 主机别名rdquo;检查是通不过

注意事项:

Que1:一般而言,在配置内核参数(gedit /etc/sysctl.conf)时,我们只需要修改kernel.shmmax.

       1 为物理内存的一半:

       物理内存grep MemTotal /proc/meminfo

       2 单位是字节。(B)

       3 RedHat上建议不要超过4G

       4 shmmax内核参数定义单个共享内存段的最大值,如果该参数设置小于Oracle SGA设置,,那么SGA就会被分配多个共享内存段,引发性能下降。为了避免多个共享内存段,我们可以修改shmmax内核参数,使SGA存在于一个共享内存段中。

Que2:在先决性条件检查时,有且仅允许一个warning(swap),网络配置也是可以的忽略的。否则,后面的问题会出现的非常的莫名其妙,一箩筐哈。

Que3:基本的包要先装上去,然后缺少哪个包再去iso镜像安装盘或者cd里面的server或packages文件夹去强行安装。而且os版本最好不要太新了。

      强行安装rpm包命令是:rpm –ivh --nodeps 名称

Que4:网络配置检查相关 su – root gedit /etc/hosts(os是静态配置的情况如下)

          格式:

“本机IP  主机名  主机别名”

注意:在redhat 企业版5首行写上“127.0.0.1 主机名 主机别名”检查是通不过的。

一般步骤:

1 挑包:

 setarch-2*   make-3*  glibc-2*   libaio-0*   compat-libstdc++-33-3* 

 compat-gcc-34-3*   compat-gcc-34-c++-3*   gcc-4*   libXp-1*

 openmotif-2*    compat-db-4*   

2 修改os版本:

  Gedit /etc/redhat-release

  redhat-4

  #Red Hat Enterprise Linux Server release 5.4 (Tikanga)

因为oracle 的官方只支持到RHEL4为止,所以要修改版本说明。把Red Hat Enterprise Linux Server release 5.4 (Tikanga)这一行注释掉,前面加上一行redhat-4。当然oracle安装完成后要修改回来。redhat-4 必须为redhat-release文件的第一行,否则安装时还会报警告。

3、修改内核参数:

   Gedit /etc/sysctl.conf

增加到文件最下面:  

kernel.shmall = 2097152

kernel.shmmax = ******(根据自己物理内存多大而定)

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

4、建立安装Oracle需要的用户、组及目录

(1)新增组和用户:

groupadd oinstall

groupadd dba

 

useradd -g oinstall -G dba oracle

passwd oracle

(2)创建Oracle的安装目录,并把权限付给oracle用户:

mkdir -p /u01/app/oracle/product/10.2.0/db_1

chown -R oracle.oinstall /u01

5、设置oracle用户的shell limit

#vi /etc/security/limits.conf

增加下面的内容到文件 /etc/security/limits.conf 文件中:

* soft nproc 2047

* hard nproc 16384

* soft nofile 1024

* hard nofile 65536

增加下面的内容到文件 /etc/pam.d/login 中,使shell limit生效:

session required /lib/security/pam_limits.so

linux

When might a full table scan be faster than using an index in MySQL? When might a full table scan be faster than using an index in MySQL? Apr 09, 2025 am 12:05 AM

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values ​​and pointers to data rows, and is suitable for non-primary key column queries.
