Re: IPL

Be careful of /etc/rc.* scripts. They are undoubtedly the future of aix
but no one told the IBM developers yet ;)

13:54:09 # du -a /etc/rc.d
8 /etc/rc.d/init.d
8 /etc/rc.d/rc
8 /etc/rc.d/rc2.d/Ksshd
8 /etc/rc.d/rc2.d/Ssshd
40 /etc/rc.d/rc2.d
8 /etc/rc.d/rc3.d
8 /etc/rc.d/rc4.d
8 /etc/rc.d/rc5.d
8 /etc/rc.d/rc6.d
8 /etc/rc.d/rc7.d
8 /etc/rc.d/rc8.d
8 /etc/rc.d/rc9.d
120 /etc/rc.d

Everything of note is in the inittab, and, that means you won't have the
control a fully plumbed rc.d is designed for.

What is the best way to start a application when the server boots up?

AIX version is 5.3

5.3 supports both inittab, or /etc/rc.X scripts. Both allow you to
control
what run level your application will start under.

If using inittab, be careful about using 'respawn' since most
applications
need to be coded a certain way to work this way.

If you want to use the /etc/rc.X method, you can create start/stop
scripts
in those directories, which makes things look more like Solaris, and
Linux.

There is a readme file in /etc/rc.d/samples for more information about
the rc startup stuff.

cheers,
