Check out:

Look at:
5. Modify the KeepAlive values as desired.

As far as making RMAN faster:  Faster disks or more of them?

Make sure where the backup files are being written are not the same disks being read from.
In AIX tcp_keepintvl is governed by "no", in Solaris tcp_keepalive_interval is governed by "ndd".


no -o tcp_keepintvl

to display, and

no -o tcp_keepintvl=<value>

to set.


ndd /dev/tcp tcp_keepalive_interval

to display and

ndd -set /dev/tcp tcp_keepalive_interval <value>

to set.

A late add after slightwv's answer, I found this source easier on my Pooh brain:

In Solaris, you read the keepalive interval like this:

ndd /dev/tcp tcp_keepalive_interval

and you set it like this:

ndd -set /dev/tcp tcp_keepalive_interval 60000

Replace 60000 with your desired value. The value is in milliseconds.

Not sure what you post provides what wasn't in the link I posted or in the post by woolmilkporc.  Please review previous post before posting duplicate information.
