In some cases, configuration changes are cancelled. For example, if the TCP/IP stack is not currently joined to the sysplex group, and a VARY TCPIP,,OBEYFILE command is issued to change the stack's dynamic VIPA configuration, the requested configuration changes are cancelled. A TCP/IP Profile SMF record is created with the following attributes:

• The NMTP_PICOSecChanged flag bits in the Profile information common section indicate the sections that would have been affected by the configuration change.
• There is one section for each record section that would have been affected by the configuration changes. A flag bit is set in the section to indicate that the requested changes were cancelled. The description of the flag bit explains the reasons why the changes were cancelled.

Configuration changes can be cancelled for the following sections:

• Dynamic VIPA addresses
• Dynamic VIPA routing
• Distributed dynamic VIPA
