Override LOGMODE Table Entries

The mainframe uses the default mode name to start a session. The default mode name can be specified in the CA XCOM Data Transport control library rather than in the NCP Line, Group, PU, LU, or switched network definitions. Specifying the default mode name in the CA XCOM Data Transport control library is easier than updating VTAM tables and it requires DLOGMOD=XCOM in the CA XCOM Data Transport Default Options Table.

Normally, the VTAM logon mode table is updated to change the RU size or pacing values. CA XCOM Data Transport permits the overriding of these values for a particular remote system in the CA XCOM Data Transport control library (CAI.CBXGPARM). For more information, see the chapter “CA XCOM Data Transport Configuration Parameters.”

Important! Do not use separate mode tables for LU 6.2. If PCs are being used, Combining APPC mode entries in the same mode table as the 3270 mode entry is recommended. VTAM does not allow any node to override the mode table name. CA XCOM Data Transport can override the mode entry, but not the mode table name.
