15.8. 64-Bit Memory Model Considerations

We suggest that you use DB2 on a 64-bit operating system whenever possible, since the limits discussed in the previous section do not exist. In addition, in a 64-bit environment, shared memory segments can be allocated and deallocated dynamically, making configuring and tuning of your DB2 server more dynamic and much easier.

DB2 currently supports the following 64-bit operating systems:

• AIX

• HP/UX

• Linux on AMD

• Linux on Intel (IPF)

• Linux on Power

• Solaris

• Windows 2003 Advanced Server
