We are having 134MB for buffer cache with same platform and version. You can
go upto 256MB,if you want. There are other list members like Kirti who can
give better explanation of this.

Hi Everyone,
We have been experiencing some I/O issues; and the systems support team (HP)
thinks that we should bump up our OS buffer cache. Currently we are sitting
at 150MB; after researching on Metalink the recommendation from Oracle for
HPUX is to have a max of 128MB of buffer cache. I have been trying to find
a document to help me understand how Oracle uses this buffer cache, and even
have opened up a TAR with Oracle; but does anyone know of a document or a
book which would help me understand this?
Metalink docs say that the buffer cache should be set to <=128MB to avoid
"losing writes"; I cannot make sense of this statement. Could someone help
me with this?
We have HPUX 11.0 with 3 550MHZ CPU's and 4GB of memory running SIEBEL's CRM
plus a couple of other databases; does anyone else have similar
configuration? If so, what is your buffer cache, and why have you set it
so?
Any help would greatly be appreciated.
Thanks,
