Hostmib only.

Exactly what version of OSR5?  (uname -X)
What "other host"?
What is between the OSR5 box and the "other host"?  Routers or firewalls?
Exactly what commands are you using to walk the MIB tree?

1.  If hostmib is properly setup, you should be able to get the entire
mib tree.  On OSR5, if you run:
        getmany localhost public iso | grep "Name" | wc
you should get 554 OID's (lines) without hostmib and about 1000 lines
with hostmib running.
        
2.  If you're getting just the System part of the tree, my guess is that
the unspecified system you're using to poll the OSR5 box is RedHat 6.0 or
6.1, which is delivered with a highly secure, but useless V2 security
        /etc/snmp/snmpd.conf
file, which exhibits exactly the above symptom.  You can also create the
exact same symptoms on OSR5 by misconfiguring
        /etc/snmpd.comm
on the OSR5 box.  If you're not sure on OSR5, just make sure that the
snmpd.comm file has:
        public    0.0.0.0       read 
in it somewhere so that everyone can read the whole tree.

On what I guess is a RH 6.x box try for snmpd.conf the following.  Be
sure to change the community names (passwords) and LAN IP address.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
