manually edit onconfig?

[June Nebab LKINY]

Planning an upgrade to 11.7UC6GE from 11.7UC5GE. Installing new version on
same $INFORMIXDIR and on same server. I noticed new onconfig params (ie:
AUTO_READAHEAD, NUMFDSERVERS, etc) that are in the UC6GE onconfig.std that
are not in my $ONCONFIG.

What is the proper way to deal with new onconfig params when upgrading:
A. Leave old (UC5GE) $ONCONFIG as is, install the upgrade, bring up
instance after upgrade, hand edit $ONCONFIG and add new params to the
$ONCONFIG afterwards.

OR

B. Hand edit new (UC6GE) $ONCONFIG and duplicate all of the settings
from old $ONCONFIG to the new $ONCONFIG, install the upgrade, bring up
instance.

Figure out what each of the new ones do, whether you want to use them or not, then add them to your old onconfig. Ideally on a test environment.

I'm a big fan of copying the current settings into the new ONCONFIG file.
It gives you a good chance to see the new parameters, like those you
mentioned - all of which were available in 11.70.xC5 BTW, so someone used
an older ONCONFIG instead of editing the new one last time. By editing the
new onconfig.std instead of just reusing the existing ONCONFIG file, you
avoid missing out on new parameters which apparently happened there with
some previous upgrade.

I would give a try to the new onconfig_diff utility, it seems to help you identify and correct some of them....
Check it out!

You should never install the new version over the current one.
If something goes wrong in the upgrade you'll have much more work to
recover.
