Upgrading HP-UX 11.0 from 32 to 64 bits

[Sebastian Cross]

Hi Guys,

I need to upgrade Oracle 8 to 9i (64-bit) in a HP-UX 11.0 box, so the system needs to run at 64 bits.
Now, I ran uname -a and I realized that the server is running at 32-bit.
Do you know How can I upgrade the OS ( HP-UX 11.0) to run in 64-bit mode. And which commands I can use to know if the hardware support that ?

Thanks for your help!

The strategy I would take is go ahead and upgrade to 11.11, and while you're at it - upgrade it to 64 bit during the upgrade. You could also consider going to 11.23, but you'd have to get information from others about an 11.00 to 11.23 HPUX conversion.

You can check with "getconf HW_CPU_SUPP_BITS" or "getconf HW_32_64_CAPABLE".

The procedure for upgrading is described in the Install and Update doc:

Hi,

You can check the following commands,

# getconf CPU_CHIP_TYPE

# getconf HW_CPU_SUPP_BITS

First, run the command "getconf HW_CPU_SUPP_BITS"; if the answer is 32 then go directly to jail; do not pass go. If the answer is 32/64 then it is possible to load a 64-bit version of the OS. Although 11.11 32 to 64 bit upgrades generally work (if /stand and / were initially created with plenty of additional space); 11.0 upgrades are much more dicey.

I would upgrade to 11.11. Oracle 11.0 code will run under 11.11. The very first thing you should do is check your firmware level as that generally needs to be upgraded prior to an OS upgrade/replacement.

Hi Sebasitian:

You don't say what model server you have. I presume that it's 64-bit capable.

# getconf HW_CPU_SUPP_BITS

...will show what you *can* run.

Release 11.0 will fall out of support in December of this year (2006). I would suggest, therefore, that you *cold-install* 11.11 or even 11.23.

Regards!
