LUMODES catalog table
Each row of the LUMODES table provides VTAM® with conversation limits for a specific combination of LUNAME and MODENAME. The schema is SYSIBM. The table is accessed only during the initial conversation limit negotiation between Db2 and a remote LU. This negotiation is called change-number-of-sessions (CNOS) processing.
Rows in this table can be inserted, updated, and deleted.
