In order for secure applications to work in a Liberty clustered
environment all the members in the cluster must have the same LTPA
keys.
About this task
The following information provides details on what must
be done for secure applications to work in a Liberty clustered environment
when you use IHS or the plug-in.
Procedure
Choose the LTPA key file from one of the cluster members
and copy it to all of the other members in the cluster. The
default LTPA key file is
${server.ouput.dir}/resources/security/ltpa.keys.
Alternatively, a new LTPA key file can be created and stored at the
default location and the LTPA key configuration can be customized.
If the LTPA keys are not dynamically reloaded after the LTPA key file
update, you must restart the cluster members or enable the dynamic
reloading of the LTPA keys. For more information, see
Configuring LTPA on the Liberty profile.
