Differences between L2000 (RP5450) and D9000

[Joe Robinson_2]

I have a D9000 server that has been used a s a test box and was able to successfully load Oracle patches (using HP-UX 11.00 and Oracle 8.1.7) on that box where it failed on the D. Are there hardware differences (aside from the obvious) that would cause this failure? Aside from the physical diffferences, the systems are set up identically.

What type of failure on the D? What error messages? The patch should load equally well on the D or on the L. There are numerous differences between a D & an L hardware wise. They are completely different architecture. They have different bus'es, (EISA/HSC on the D, PCI on the L) different CPUs, etc. The D can run 32 or 64 bit HP-UX, whereas the L can only run 64 bit.

The "bitness" of the DB could cause you problems. If you have 64-bit installed on the L and 32-bit on the D and try to load a 64-bit patch on a 32-bit Oracle instance, it wouldn't work.

More information would help us to further help you.

There has to be a difference, but I would not look at the hardware.

We run Oracle on D class boxes and rp4540 L2000 servers.

We have had no trouble with patches and found the 32 bit to 64 bit word conversion to be time consuming but possible.

I would first start by looking at the kernels.

Now D class boxes are mostly running 32 bit OS(The D380 will run 64 bit 11i/11), the rp5450 L2000 servers will only run 64 bit HP-UX.

Your issues could have to do with the 32 to 64 bit word size issue. I'm attaching that document.

Thanks for the response Patrick. As far as I know, it has the 64-bit version on the D (I didn't load it, so I won't swear by that, though). What can I verify the build with?

[Patrick Wallek]

If you want to see what HP-UX "bitness" you are running you can use:

# getconf KERNEL_BITS

Which will return 32 or 64.

However, just because you are running a 64-bit OS does not necessarily mean you are running 64-bit Oracle. You can run 32-bit Oracle on a 64-bit machine quite easily.

To find out what Oracle is installed you could try going to $ORACLE_HOME/bin and do a 'file *' to see if any of the executables show up as ELF-64. Other than that, I don't have a clue how to see which version of Oracle was installed.
