In my experience, the WAS Integrated Solutions Console typically will show updates made from other sessions when you re-visit or refresh a page; however, there have been a few cases where this doesn't work as expected, and these usually represent bugs in the console.
I ran a quick test to create a SIB destination from wsadmin
while I was logged into the console. I found that the change wasn't recongized when I simply re-visited the buses pages; however, when I navigated to most other pages, I was greeted with the "Your workspace has been auto-refreshed from the master configuration. You can disable auto-refresh in your user preferences." message that typically indicates when a change from another session was made. Then, after navigating back to the buses information, my new destination was visible without having to log out and log back in.
It seems that the buses pages are not detecting these changes, and this sounds like a bug. You might consider logging a PMR with IBM.
Otherwise, first, ensure that workpsace refresh is enabled (System administration
> Console Preferences
> Turn on workspace automatic refresh
) - this setting is most likely already enabled by default - and then you may be able to use the workaround that I found by navigating away from the buses pages rather than logging out.
