Parameter documentation
Within this time span, the J2EE Engine must log on to the dispatcher. If
not, it is assumed that the J2EE Engine had problems starting and it is
started again. You can determine the number of incorrect start attempts
using parameter rdisp/j2ee_error>. If this
number of start attempts failed, this deactivates the starting of the
J2EE Engine. By dynamically switching using parameter
rdisp/j2ee_start>, you can reactivate the
restart.
