Memory and disk conditions required for DB2 Installation

DB2 database installationHow can I install it at will? The answer is no. Everything must comply with certain standards. The following describes the standard requirements for DB2 database installation, which can be used as a reference for you to install the DB2 database.

Disk Space Requirements

How much disk space does DB2 9 Data Server require? This is closely related to the options during installation and the file system format set by the operating system on the machine. The Installation Wizard of the DB2 9 product dynamically estimates the approximate size of disk space required for various installation options. On Windows, if the system sets the file storage in the FAT format, more disk space is required than the NTFS format. When estimating disk space, you should not forget to allocate space for tools and communication software related to DB2 9.

Memory space requirements

Running the DB2 9 data server software system requires at least MB of memory. A computer system running the DB2 9 database server and the DB2 9 graphical user management interface tool requires at least MB of memory space. To improve the performance of DB2 9 during runtime, we recommend that you configure a memory of more than 1 GB to run the DB2 9 data server product. If other software needs to be run on the computer, the memory should be increased. Pay attention to the following points when increasing the memory:

1. If the hardware environment running the DB2 9 product is the Intel anteng 2 processor and the second edition HP-UX 11i operating system, the minimum memory required is 512 MB.

2. the DB2 9 data server is configured with the lowest memory. By default, five concurrent client connections are supported. Each increase of five concurrent clients requires 16 MB of memory.

3. The memory requirements of the Data Service System are not only related to the number of guest users, but also closely related to the frequency of data updates, adjustments, and Optimizations in the data system. The new version of DB2 9) introduces an automatic memory allocation optimization mechanism, data actions such as sorting, packaging buffering, list locking, and buffer pool allocation during the running of DB2 9 database products can all be adjusted and allocated using automatic mechanism.

4. in Linux, we recommend that you set the size of swap partition to at least twice the system memory.

Following the two requirements described above, DB2 database installation can be completed smoothly. I hope the content described above will be helpful to you.
