SYMPTOMS
========
After you apply SNA Server 4.0 Service Pack 2 (SP2), TN3270 users may experience
one of the following problems:
- The first TN3270 client that connects to an OnDemand connection fails. The
connection is brought up, but the client remains in a not responding state,
and the LU shows in SSCP state. This only affects the first client; all
subsequent clients connect successfully. If the connection is set to Server
Startup, everything works fine.
- If the host uses DDDLUs, TN3270 clients may display the following error
message when they start a host session through the SNA Server TN3270 server:
TN3270E Service Message 525
The PU is active for LU <LU name>.
You may continue to wait, or terminate your session.
After the error message appears, the user may be able to obtain a host session
by disconnecting and then reconnecting the session from within the TN3270
emulator.
