How to reset the portal pages database in 6.x
It is possible to set permissions and pages up so that no one can log in. If this happens, it's necessary to reset the portal database to defaults. This is a procedure for doing so.
To do this, from a root shell:
# /etc/init.d/groundwork stop gwservices
then from a root mysql cli:
drop database jbossportal;
create database if not exists jbossportal;
grant all on jbossportal.* to 'jboss'@'localhost' identified by 'jboss';
than back at root shell:
# /etc/init.d/groundwork start gwservices
This will wipe out all non-default users and passwords, as well as any custom portal pages, dashboards, etc.
It's a good idea to back up the jbossportal database before customizing dashboards to avoid this problem.
