JES2 supports I, J, K, L, M, N, and B (SRCB) records. The initial signon (I) and response signon (J) records must be the only records in their respective buffers. The other records may be sent in the same buffer. JES2 allows a user to specify his own function for SRCB types S-Z.

You can define a non-path manager connection to JES2 by entering NODE(n) PATHMGR=NO at initialization. JES2 sends only I, J, and B records to non-path manager nodes.
