Re: IBM i Access for Web vs IBM Navigator for i

Finally opened a pmr with IBM Support on the performance issue.

Since we don't use IPv6 on our network, I was instructed to modify the
configuration options for each of the admin servers to use IPv4 (see
below), and bring the Java group PTF up to the current level to get the
most recent fixes. Also needed to apply a test patch of IBM's dojo
javascript framework to work with Firefox v25.

Big improvement in responsiveness- order of magnitude better (5-10 seconds
versus 60+ seconds previously mentionedI). Not snappy, but usuable. I
really wasn't expecting subsecond responses it's a only P05 group machine.


Here are some instructions for turning off ipv6 for this application

END the HTTP Admin server first

Issue the following EDTF statements:

EDTF '/QIBM/UserData/OS/OSGi/LWISysInst/admin/lwi/conf/overrides/i5.javaopt'
EDTF '/QIBM/UserData/OS/OSGi/LWISysInst/admin2/lwi/conf/overrides/i5.javaopt'
EDTF '/QIBM/UserData/OS/OSGi/LWISysInst/admin3/lwi/conf/overrides/i5.javaopt'
EDTF '/QIBM/UserData/OS/OSGi/LWISysInst/admin4/lwi/conf/overrides/i5.javaopt'

Add the following lines to each file:

-Dcom.ibm.cacheLocalHost=true
-Djava.net.preferIPv4Stack=true
-Djava.net.preferIPv6Addresses=false

START the http admin server. It may take a while for it to start completely..
