VTAM® can dynamically create an adjacent SSCP list. This table consists of all of the adjacent SSCPs with which VTAM has an SSCP-SSCP session. VTAM can then route session-establishment requests to all active adjacent SSCPs until the correct SSCP is found. If you code adjacent SSCP tables and use dynamically defined adjacent SSCP tables, VTAM uses the appropriate adjacent SSCP table without being affected.

To enable dynamically defined adjacent SSCP tables, code the DYNASSCP start option. If you specify YES and VTAM does not locate an appropriate adjacent SSCP table, VTAM dynamically routes the session-establishment request to all active adjacent SSCPs until the correct SSCP is found. If you specify NO, VTAM does not perform this dynamic routing.

By using the dynamic adjacent SSCP table function in conjunction with the adjacent SSCP selection function of the session management exit routine, you can control the order of the dynamic adjacent SSCP table. See Improving performance.
