Error description
A data set with TN3270 server profile statements was specified on a VARY TCPIP,,OBEYFILE command to a TCP/IP stack by mistake. The data set contained sequence numbers in columns 73-80. While processing the statements, the TCP/IP stack entered a loop on an ENCRYPTION statement. The stack had to be cancelled to resolve the loop. Example: ENCRYPTION 00140502 The following message may be seen repeatedly: EZZ0401I LIST IS EMPTY IN FILE: 'OBEY.DATA.SET' ON LINE: xx AT: '00140502'
Local fix
Restart the stack
Problem summary
**************************************************************** * USERS AFFECTED: All users of the IBM Communications Server * * for z/OS Version 1 Release 12 and 13: * * TCP/IP stack * **************************************************************** * PROBLEM DESCRIPTION: A VARY TCPIP,,OBEYFILE command was * * mistakenly directed to a TCP/IP * * stack instead of the TN3270 Telnet * * server. The data set specified on * * command contained TN3270 profile * * statements with sequence numbers. * * When the stack processed the * * ENCRYPTION statement it * * entered a loop and had to be * * restarted. * **************************************************************** * RECOMMENDATION: * **************************************************************** Even though the TN3270 server can no longer be started in the TCP/IP stack address space, the TCP/IP stack profile processor can still process the TN3270 profile statements. The stack should process the statements and then issue message EZZ0209I indicating that the statements have been ignored. There was an error in the original implementation of support for the TN3270 ENCRYPTION profile statement. This error caused the stack to enter a loop if sequence numbers were specified on the statement. +-------------------------------------------------------------+ + Please check our Communications Server for OS/390 homepages + + for common networking tips and fixes.

Problem conclusion
The TCP/IP stack profile processing has been corrected to flag sequence numbers as errors for the TN3270 server ENCRYPTION profile statement. * Cross Reference between External and Internal Names YACCFYAC (EZACFYAC) YACCFYAC (EZACFYAC)
