Upgrading to 32 or 64 bit

We are in HPUX 10.20, SAP 4.0b, Oracle 806. We are planning to upgrade the OS only to 11X 32 or 64 bit versions.

When we upgrade to 64 bit HPUX 11X, will there be any impact with some of the executables outside SAP (RFC's etc.)? where I don't think there would be an impact if we can stay at 32 bit.

There are no runtime or RFC issues with your 32bit applications or performance related issues. After the upgrade you should tune your kernel as documented in the below notes. If you have any further consulting or product issue questions please contact us at www.sap.hp.com/public or your local HP Response Center.
