[NOR AZLY MOHD NOR]

Hi,
I have question abt the minimum specification of HP-UX hardware to do the upgrading to SAP v4.6C and implementing mysap.com.
Currently I have 3 K-Class application server running SAP v3.1H.So how can I get a information for the minimum HP hardware spesification or somebody have a white paper to solve my problem?

Thanks and Best Regards,

AZLY,
The first place you might look is on the sapnet web site for the sizing information. Since all this is dependent on the number of users, applications you are running, and the
size/type of your db, I don't think anyone will
be able to give you any hard and fast rules.

Don't forget to check your OS level. You didn't state if you were on 10.20 or 11.0. If you can I would suggest that you migrate to 11.0 at least and go to 64-bit. Little known fact that we know now.... you can have a 32 bit 4.6C installation (SAP note 194885). But it is our current understanding that 4.6C will be the LAST 32 bit version available, so migrate if you can.

Then you will undoubtably have to upgrade what ever flavor/version of db you are running. See if you can't do this well before hand and have that part out of the way.

There are tools to help make SAP upgrading easier. Run the prepare script, it will make suggestions you need to follow in order to make your upgrade so smoother. You will find the Upgrade Assistant quite helpful, as you can monitor the process from anywhere that you have access to your network.

Part of the upgrade will involve creating what didn't exist in 31H called Central Address Management or CAM. This took probably the largest amount of time during the upgrade.

What I can suggest to you is that you are getting ready to take a pretty good size leap. We went to 4.5B from 3.1H in 2000 and that was a pretty good upgrade. Just recently (November 8) went to 4.6C on production. Just using 45B on Friday and the users coming back on Monday and being on 46C was an eye opener. Fortunately we had gone through training with all of them beforehand.

We were fortunate (for the very first time)that we also had a year to practice our upgrade stratagy (45B to 46B)on what was our old production db server, a K570 with 2 processors. We went through 4 upgrade runs, always copying the production database back to it before we started the upgrade run. 3 were successful one was not.... but that is why you practice.

Our production systems run on 2/L2000 3-ways, one for the Central Instance, and one strictly for the db. The biggest thing I have seen since upgrading is that our swapinfo now reports swapping where under 4.5B it didn't
