I need to change the MTU size on three different systems (all AIX 5.3
ML03), and I need to avoid any user down-time if necessary. Normally,
I run the following commands:
ifconfig en0 down detach
chdev -l ent0 -a jumbo_frames=yes
chdev -l en0 -a mtu=9000
ifconfig en0 up
Then go to smit tcpip, select "Start Now", and that does the trick.
1) Is there a way to automate the last step?
2) If I do this during a period of fairly low activity, how likely am
I to get away with it (I'll warn the users ahead of time, but would
like to be able to tell them that the system *probably* won't go down)
If it makes any difference, one of these servers is an application
server, and the other two are back-end Oracle DB servers that it
communicates with. I'm hoping to see some improvement in Oracle
performance from this as well (or am I kidding myself!)
