multiple archive destinations

RDBMS: 8.1.6.2 OS: AIX 4.3.3 Our large (600G) insert-intensive (17Meg / min) database has 24 on-line redo logs (8 each on 3 disks used in round-robin fashion) and occasionally has problems with the archiver being unable to keep up with the data fill rate. When this happens on-line redo logs fill faster than the ARC process can write them. I have successfully used more than one ARC process but of course all ARC processes are writing to the same destination (which becomes the limiting factor).

What I'd really like to do is use more than one archive log destination - with 2
(or more) ARC processes - each writing to a separate destination. But reading
through the manual it looks like the multiple archive destination facility was developed for multiplexing each redo log to more than one destination (for hot-standbys for example) - rather than each redo log to one of several destinations depending on which ARC process is working on it.

Is there any way to accomplish my purpose?

thanks,

..tom
