Oracle 7.3.3.5 on AIX and HPUX

Dear Oracle specialists

I am as a DBA responsible for a couple of RS 6000 AIX and some HP 9000 machines running Oracle 7.3.3.5. (7.3.3.5 patchset applied)

I have the following questions:

I read somewhere that having LOG_BUFFERS > 128 KB on AIX is reducing performance drastically. Is this right ?

There are several problem reports on the Oracle Developer Library CD (Nov. 1998) that ASYNC_IO=TRUE or DB_WRITERS > 1 are causing problems. Is that true ?
If this is not true which of these two options is preferable ?

On one machine I somehow managed that the agent is running and can be used with the Oracle Enterprise Manager but on all other machines I had no success at all.

I receive the error
NMS-00007: DBSNMP failed to allocate memory on some of the machines

On the hpux machines the agent starts and detects the listener but no databases.

Is there a document somewhere which explains step by step how to set up an agent that works or is this a hopeless wish to manage several databases with OEM ?

So many questions ...

With best regards
