Figure 11: Enabling 44-bit System Address Mode using RBSU

6. Ignore the Warning message:

Caution: Enabling 44-bit Address Mode may cause problems with an operating

system if it does not support 44-bit memory addressing.

7. Select Enabled to turn 44- bit memory addressing ON.

8. Exit all RBSU menu screens using the Esc key.

9. Press the F10 key to confirm your changes and reboot the system.

10. Confirm the new 44-bit System Address Mode by looking at the RBSU splash screen during system boot, as

described in Step 1.

Increase crash kernel size

The HP ProLiant DL 980 supports up to 4 TB of memory so you should use the kernel boot option crashkernel to

adjust the crash kernel size accordingly. Keep in mind that the Linux kernel has a maximum limit of 896 MB for crash

kernel size.

This section describes several recommended best practices for running Oracle 11gR2 (11.2.0.2) on the HP ProLiant

DL980 Server:

 Test Hyper-Threading (page 24)

 Use HugePages (page 24)

 Enable Oracle NUMA optimizations (page 25)
