MAI-OC Mode Table and Bind Checks

The following logmode table should be assembled and linked into the appropriate VTAM library (for example, SYS1.VTAMLIB in z/OS). It accurately defines MAI-OC session characteristics and results in the most efficient use of a session. It should then be specified on all MAI-OC VTAM APPL statements using the MODETAB=MAIVMODE operand:

MAIVMODE  MODETAB
MAIVMDE   MODEENT LOGMODE=MAIVMDE                                         *
          FMPROF=X'03'                                                    * 
          TSPROF=X'03'                                                    * 
          PRIPROT=X'B1'                                                   * 
          SECPROT=X'90'                                                   * 
          COMPROT=X'3080'                                                 * 
          RUSIZES=X'8585'                                                 * 
          SSNDPAC=X'00'                                                   * 
          SRCVPAC=X'01'                                                   * 
          PSNDPAC=X'01'                                                   * 
          PSERVIC=X'010000008000800000000000'

The following table shows the checks MAI-OC performs on BIND parameters at session initiation. The bits shown are checked by MAI; bits not shown are not checked. Invalid BIND parameters are rejected by MAI.
