VTAM Logmodes

To associate an LU6.2 mode name with specific session characteristics (for example, Class of Service, session level pacing), some implementations of APPC require the matching VTAM logmode names with the derived characteristics to be defined to the MCT via the LOGMODE parameter. If omitted, the VTAM default logmode values for those parameters are used.

Note: Your product can successfully initiate sessions using LU6.2 mode names with or without matching VTAM logmode names. However, other implementations, such as CICS and OS/2, require the LU6.2 mode name to match the VTAM logmode name to successfully activate sessions initiated by these products.
