SNA Server Support for ACTPU (ERP) and ACTLU (ERP)

MORE INFORMATION

• When receiving an ACTLU (cold) command, SNA Server resets the SSCP-LU session (which is used to carry the logon screen) and the PLU-SLU session if the PLU-SLU session is active. (The PLU-SLU session is used for applications and data transfer after the user has logged on to an application.)
• When receiving an ACTLU (ERP) command, SNA Server resets the SSCP-LU session. If there is an active PLU-SLU session, this session is left active.
• The ACTLU (ERP) command is used in conjunction with the ACTPU (ERP) command. As for ACTLUs, if a cold ACTPU command is issued by the host, SNA Server resets all the sessions using that PU; SNA Server resets all the 3270 sessions.
• If an ACTPU (ERP) command is issued by the host, SNA Server resets only the PU-SSCP session.

• An ACTPU (ERP) request was received.
• The ACTPU (ERP) was received when the PU-SSCP session was already active.
• The ACTPUERP Registry entry is not defined.
