Hi,
I followed deployment manual from [1] and configured two DCs with
single cluster each.
During configuration of the UI I noticed that in optimizer result tab there
was:
Status: Data refresh failed: undefined
with Martin's help we found that when setting
security.mixed_content.block_active_content
This happens when WebAdmin page is loaded as HTTPS and UI plugin uses
active content (XHR object, script etc.) that loads data as HTTP.
Loading HTTP content in HTTPS page is considered security vulnerability
and should be avoided. By default, Firefox blocks mixed active content.
More details here: https://support.mozilla.org/en-US/questions/967115
Disabling mixed active content in browser is not a proper solution.
UI plugin should load its content in a way that is compatible with
protocol (i.e. HTTPS) used for enclosing page.
to false in FF configuration it works and I can see:
Status: Solution received
During the installation of second host network configuration failed
and I opened BZ [2].
When I restored network configuration to the host I wanted to
provision vms to see optaplanner
suggestions but my rhel6 failed to start any vms due to:
