SYMPTOMS
The SNA Server applet generates a Session Error 2574 when you attempt to
establish a connection with an SNA Server.
CAUSE
This error may occur if the 3270 applet is trying to connect to an LU Pool
that is defined on the SNA Server and that LU Pool doesn't have any LUs
assigned to it. If you start SNA Server Admin and put the focus on the LU
Pools windows, a "No Assigned LUs" message may be in the right side of the
window.
RESOLUTION
To correct this error, add LUs to the LU Pool that the 3270 Applet is
trying to establish a connection to. Also, changing an LU Pool definition
requires that all affected SNA Servers be restarted to pick up the
configuration change. In SNA Server Admin, all affected servers will appear
as "Active [Out of Date]" to indicate that the server needs to be restarted
for the configuration change to take effect.
