What are the requirements for the Oracle 10g database software and hardware environment?

The following articles describe the specific operations required for the software and hardware environment of Oracle 10 Gb database. If you are interested in the actual operations, you can click to view the following articles. I hope it will help you in this regard.

1. Check hardware requirements

The system must meet the following minimum hardware requirements:

At least MB of physical memory

The following table describes the configuration relationship between the physical Memory RAM) and the swap zone swap space during installation.

RAM Swap Space

1024 MB to 2048 MB 1.5 times RAM

2049 MB to 8192 MB equals to RAM

More than 8192 MB 0.75 times RAM

At least 400 MB of free disk space in the/tmp directory

1.5 GB to 3.5 GB disk space is used to install Oracle 10 GB database software. The specific size is determined by the installation type.

1.2 GB disk space for Database Pre-configuration file system storage (optional)

Note:

Disk Space Requirements for Using ASM (Automatic Storage Management) and RDS (raw device storage) are described in a later section.

If you select Automatic backup configuration, enable flash recovery area) requires additional disk space, you can also specify it in the file system or ASM (Automatic Storage Management) disk group.

Ensure that the system meets these requirements:

Confirm the physical memory size and enter the following command:

 
 

  
  
grep MemTotal /proc/meminfo  
 
 

If the physical memory size is smaller than the recommended memory size, you must increase the memory size before installation.

Confirm swap space in the swap area), and type the following command:

 
 

  
  
grep SwapTotal /proc/meminfo  
 
 

Example:

 
 

  
  
as3$grep SwapTotal /proc/meminfo   
  
  
SwapTotal: 2048248 kB   
 
 

If necessary, check the information about how to configure the swap space in the swap zone in the operating system documentation to modify the swap space) configuration.

Confirm the available RAM and swap zone swap space), and type the following command:

 
 

  
  
free  
 
 

Example:

 
 

  
  
as3$free   
  
  
total used free shared buffers cached   
  
  
Mem: 503084 490356 12728 0 2432 345224   
  
  
-/+ buffers/cache: 142700 360384   
  
  
Swap: 2048248 72692 1975556   
 
 

It is recommended that you perform repeated tests after several seconds of delay. The above content is an introduction to the requirements of the Oracle 10g database software and hardware environment. I hope you will gain some benefits.
