Subject: HP-UX

Problem Description: Oracle crashes because of an HP-UX system problem

Method for parameters calculating

Primer / Example:

nfile = (16*(NPROC+16+MAXUSERS)/10+32+2*(NPTY+NSTRPTY+NSTRTEL))

NPROC = (20+8*MAXUSERS) = 1620

MAXUSERS= 200

NPTY = 512

NSTRPTY = 60

NSTRTEL = 60

Symptoms Autopatch error / Još jedna moguća greška:

Unable to allocate memory in procedure aiumb().

Cause: MaxDsiz kernal parameter is set to very low

Fix: Increase maxDsiz kernal parameter to 512 MB or 1GB .

Restart the patch from start.

Our test scenario:

maxdsiz changed from 268435456 to 1073741824 (0X100000000).

Change performed, kernel rebuilt, patch started from the beginning.
