This article was previously published under Q158775 SUMMARY
The following problems have been observed by various third party 3270 emulation
products when being used with SNA Server:
- A User is allowed to open multiple instances of same pool
When you assign a single pooled 3270 LU to a user or group using the SNA
Server Administrator program or SNA Server Manager, the 3270 emulator being
used should not allow the user to open multiple sessions through a single
instance of the pool. However, in some cases it does allow the user to open
multiple instances of the pool.
This problem has been observed with some third-party emulators that do not
closely follow the SNA Server 3270 Emulator Interface Specification. SNA
Server does not prevent the emulator from attempting to open multiple
instances of a single pooled LU, because the client may be communicating
through multiple SNA Servers.
To grant access to multiple pooled sessions, the administrator must grant
multiple instances of a pooled LU to the user or group.
The following products are known to exhibit this problem:- IBM Personal Communications/3270 v4.0 (fix available from IBM)
- Attachmate Extra! Personal Client v6.1 (32-bit)
- A User is allowed to manually enter a 3270 LU or pool to open
Some emulators allow the user to manually configure the 3270 LU name or pool
name for a user to open. However, this circumvents the User/Group/Workstation
3270 LU assignments configured on the SNA Server. While a user will not be
allowed to open an LU that they do not have access to on the server, the
emulator should only display a list of LU's assigned to the user (which the
emulator retrieves by calling the sepdcrec() SNA client API function).
