Problem summary
**************************************************************** * USERS AFFECTED: * * All users of the IBM Communications Server * * for z/OS Version 2 Release 1 IP: SMTP * **************************************************************** * PROBLEM DESCRIPTION: * * An ABEND0C4 occurred in SMS module * * IGDERDM2 when a Modify SMTP,SMSG * * command was issued before SMTP * * had fully initialized. * **************************************************************** * RECOMMENDATION: * * Apply fix. * **************************************************************** The problem can be summarized as follows: 1. SMTP was started. 2. Before SMTP had finished initialization, an operator issued a MODIFY SMTP,SMSG command. 3. The address of the external interrupt handler had not been filled in yet, so MVPIOINT took a wild branch that eventually lead to an ABEND0C4 in SMS module IGDERDM2. +-------------------------------------------------------------+ + Please check our Communications Server for OS/390 homepages + + for common networking tips and fixes.

Problem conclusion
MVPOCM has been changed to verify that the external interrupt handler address has been set before scheduling an IRB for MVSIOINT to process the MODIFY SMTP,SMSG command. If it has not been set, MVPOCM will issue new message EZY1979I to inform the operator that they should try the SMSG command again later. The following documentation updates for the new message were included in the V2R1 IP Messages Volume 3 (EZY): EZY1979I SMTP cannot accept the MODIFY command - try again later Results: The MVS platform received a command to modify SMTP, but the command was not accepted because SMTP initialization had not completed. Example: F SMTP,SMSG,ST EZY1979I SMTP cannot accept the MODIFY command - try again later System Action: SMTP continues. Operator Response: Issue the command after SMTP initialization completes. User Response: Not Applicable. System Programmer Response: No Action Needed. Problem Determination: Not Applicable. Source: z/OS Communications Server TCP/IP: SMTP Module: MVPOCM Routing Codes: 10 Descriptor Codes: 12 Automation: This message is sent to the console where the command was entered. Automation could be used to issue the MODIFY command at a later time. * Cross Reference between External and Internal Names EZAAA00A (MSMVP ) EZACA01Y (MVPOCM )
