Session control start options

Table 1. Start options that affect session control. These start options can be displayed as a group with the DISPLAY VTAMOPTS,FUNCTION=SESSCONT command.
Start option Description
AFFDELAY Specifies the number of seconds after a session termination that Generic Resource affinities for non-syncpoint, non-Limited Resource LU 6.2 sessions should be retained
APPNCOS The APPN Class of Service that is used if the requested Class of Service cannot be found
ASYDE Whether to terminate a session when an asynchronous device end RU is received from a local non-SNA device
AUTORTRY Specifies which adjacent node activation will cause a retry of pending automatic logon requests
BNDYN Indicates how nodes are added dynamically to adjacent cluster routing lists
BNORD Indicates the order VTAM® does cross-subnet searches
CDRDYN Specifies whether the host is authorized to dynamically define CDRSC representations of cross-domain resources
CMPMIPS Use to determine the amount of time for adaptive mode compression
CMPVTAM The data compression level to be used for sessions with the application programs running on the host
CPCDRSC Whether VTAM allows applications or LUs to initiate and establish sessions to a dynamic LEN CP ILU
DIALRTRY Specifies whether VTAM should continue searching for a switched resource after a dial–out failure
DLRORDER The way VTAM locates a DLUR PU
DUPDEFS Whether APPN should continue searching for the target resource when the resource has been found but is not active
DYNADJCP Whether dynamic entries are created in ISTADJCP for adjacent APPN nodes
DYNASSCP Whether VTAM dynamically routes session establishment requests to all active adjacent SSCPs if no appropriate adjacent SSCP table is defined
DYNDLGMD Specifies the default logon mode name used for dynamic cross-domain resources when the resource is acting as the secondary logical unit (SLU) and a logon mode name is not otherwise provided
DYNLU Whether independent LUs can be dynamically defined
DYNMODTB Specifies the name of a logon mode table used for dynamic cross-domain resources to correlate each logon mode name with a set of session parameters when the resource acts as the SLU
EXPFLTRM The EXPFLTRM start option defines the number of expedited data flow control (DFC) and session control (SC) request units (RU), that VTAM allows a boundary-attached LU to send without receiving a response from the partner LU.
HOTIOTRM The percentage of the I/O buffer pool that can be used by one session before the amount is considered to be excessive and the session is terminated
HPRSESLM Specifies the maximum number of sessions that should be assigned to a single RTP pipe
ISTCOSDF Indicates the resource types that can use the ISTCOSDF logmode entry
RESUSAGE The number of times an APPN resource (node or TG) can be used for routing before it is considered overused
ROUTERES The relative amount of resistance to having this APPN node perform intermediate session routing
SMEAUTH Controls session management exit (SME) authorization data without having to modify or code an SME
SORDER The order in which to search APPN and subarea networks when a network search request is received from a subarea network
SSCPDYN Whether VTAM can dynamically add entries to an adjacent SSCP table
SSCPORD The order in which VTAM searches an adjacent SSCP table
SSEARCH Whether to search a subarea network when a network search request is received from an APPN network
SWNORDER The way VTAM locates a switched PU
UNRCHTIM Specifies the default number of seconds that a partner node for a session path through an Enterprise Extender connection network is considered unreachable after certain Enterprise Extender connection network failures. During this period, the path through the Enterprise Extender connection network to this partner node will not be considered for new sessions or HPR path switches. UNRCHTIM also specifies the limit for the number of unreachability records associated with an Enterprise Extender connection network before that connection network is considered unusable for session route selection for new sessions and HPR path switches.
