Two-phase SMF record creation for VIPADYNAMIC/ENDVIPADYNAMIC profile statement information
You can use the VIPADYNAMIC and ENDVIPADYNAMIC profile
statements and their substatements to configure dynamic VIPA and Sysplex
Distributor support in the TCP/IP stack. The following sections in
the TCP/IP profile SMF record provide information about this configuration:
- Dynamic VIPA addresses
- Provides configuration information from VIPABACKUP, VIPADEFINE, and VIPARANGE substatements
- Dynamic VIPA routing
- Provides configuration information from the VIPAROUTE substatement.
- Distributed dynamic VIPA
- Provides configuration information from the VIPADISTRIBUTE substatement.
Processing of these configuration statements occurs after
the normal profile configuration processing, so more than one SMF
record is needed to provide the configured information. When a profile
data set contains these configuration statements, the resulting TCP/IP
profile SMF records are created in two phases:
- Phase one
- During normal profile configuration processing, the first TCP/IP
profile SMF record is created. It contains the following sections
of information:
- TCP/IP identification section
-
- The value in field SMF119TI_Reason indicates that the record is incomplete.
- Field SMF119TI_RecordID contains a correlator value, so that you can correlate this first record with the additional record or records that are created during Phase two.
- Profile information common section
- Field NMTP_PICOSecChanged indicates the sections affected by the statements in the profile data set
- Sections of configured information
- If other profile statements other than the VIPADYNAMIC and ENDVIPADYNAMIC statement block were specified in the profile data set, their information is provided in the Phase one SMF record.
- Phase two
- When the VIPADYNAMIC and ENDVIPADYNAMIC profile statements are
processed, an additional record or records is created to provide the
configured information. These records contain the following sections
of information:
- TCP/IP identification section
-
- The value in field SMF119TI_Reason indicates whether the record is complete or incomplete. If more than one additional record is needed to support all the configured information, all the additional records except the final record indicate that the record is still incomplete. In the final record, field SMF119TI_Reason indicates that the record is complete.
- Field SMF119TI_RecordID contains a correlator value, so that you can correlate the record written during Phase one with the additional record or records which are created during Phase two.
- Sections of dynamic VIPA and Sysplex Distributor configured information
- If other profile statements other than the VIPADYNAMIC and ENDVIPADYNAMIC statement block were specified in the profile data set, their information has already been provided in the Phase one SMF record.
