Session Problem 7
Sessions terminate abnormally.
Solutions:
If sessions terminate abnormally, you might not have used the correct buffer
size when configuring the Gateway-ST. A TE session, for example, might
terminate with the following message:
%SNATERM-E-SESNOLACT, session no longer active
-SNA-E-ABMSESTER, session terminated abnormally
You must check the line and circuit counters.
Check the line counters with the following command:
SNANCP> SHOW KNOWN LINE COUNTERS
If the display includes the following message, change the line buffer size to
reflect the value of MAXDATA specified in the IBM system:
1
Receive failures, including:
Frame too long
Ensure that the PU segment size matches the line buffer size.
Check the circuit counters with the following command:
SNANCP> SHOW KNOWN CIRCUITS COUNTERS
If the display includes the following message, change the buffer size to reflect
the value of MAXDATA specified in the IBM system:
1
Remote station errors, including:
FRMR sent, I-frame too long
1
Data errors inbound, including:
Frame too long
To change the buffer size, use the SNANCP SET LINE command. See the
DECnet SNA Gateway-CT and ST Management book for information on using
this command. To ensure that the correct buffer size is used next time the
Gateway-ST is loaded, edit the SNA configuration file on the load host:
SYS$COMMON:[SNA$CSV]SNAGATEWAY_gateway-node-name_SNA.COM
