When changing the TBSM Server security configuration, adding a realm, for example, the UI allows me to add, save and apply the new realm, but when I navigate from the page and return my new realm is gone.
Resolving the problem
There could be many reasons why this error could occur, but one possibility that is easily addressed is a corrupted WebSphere cache.
To remedy this, please stop the TBSM Dashboard server and clear all the files in the
subdirectories and child subdirectories, and restart your TBSM Dashboard server.
