Running 5.3 and 3.8.1 on AIX

[Tom Patton]

I’m planning to install 5.3 on an AIX box with 3.8.1 running.  I want to install 5.3 without impacting 3.8.1 and do a phased migration.

I wonder how the install will impact my current production environment.

For example:

o hci account – I still need this to point to 3.8.1

  what can be done so that hci can be used in both environments,

  or should I create another account for 5.3?

o HA environment

  This will be an issue when I run both versions in production.

  Does a new account solve this?

Any pitfalls or areas to watch for would be greatly appreciated.

Thank you

As far as the hci user, you can go into the .profile file in AIX and force the environment to /hci/root3.8.1P.  The code should look like:

# Use this line to get the machine’s default root.

setroot

# Use this line to get a 2.1 (i.e., HCI-LINK) root (if installed)

# setroot /hci/hciRel_v2.1

#

# Modify this line to get a 3.0 (i.e., Cloverleaf) root

setroot /hci/root3.8.1P

We did the same thing, except for HA; a couple of months ago and we didn’t have any problems whatsoever.

I hope this helps.

Much simplier than that.  Remember there is always a default root and for each root a default site.

If you want to setroot to 3.8.1P just by executing the setroot command, simply change the default root.

Edit the file $QUOVADX_INSTALL_DIR/integrator/productinfo/defaults and change the root= to point to your 3.8.1P root.  Later, when you want 5.x to be the default, change it again.

Likewise, you can set the default site by editing the file $HCIROOT/roorInfo.  Add the line: site=
