Updating DTF Node Records
The DTF NODE RECORDS screen is accessed by selecting option C on the PRIMARY MENU, then by selecting option D on the CONFIGURATION screen, and pressing Enter. One DTF node record exists for each DTF node which IBM® Connect:Direct® users can sign on to directly. Following is an example of the screen.
Note: Changes made to the DTF node record parameters are immediately reflected in the active system.
The following table describes the Entry fields:
|DTF NODE NAME||Contains the name of a DTF node. This is a 16-character field.|
|NETMAP DDNAME||Specifies the DDNAME of the IBM Connect:Direct network
map file to be used when initiating a signon to this node. The network
map must have an adjacent node definition for this node, but need
not be exactly the same network map file the node is using. You must
code this value; no default is available.
The NETMAP DDNAME is defined to CICS® using RDO and is the FILENAME used by CICS. You must have one network map file for each node and you must have the DTF node record for each node you want to sign on to.
|DUMMY ID FOR DTF SIGNON||Specifies the IBM Connect:Direct userid to be used to initially establish the VTAM® session with the DTF. Multiple CICS userids are required if a DTF can have multiple CICS Interface systems signed on concurrently. If you are using the DGASECUR macro to define your IBM Connect:Direct security exit, this parameter must match the CICS parameter coded for that macro. You must code this value; no default is available.|
|SUPPRESS CONNECTION AT STARTUP||Contains the toggle for startup connections. This is a 1-character field. If the field contains Y, the connection between the specified DTF node and the IBM Connect:Direct system is suppressed when the IBM Connect:Direct software is started. If the field contains N, then the connection is made. The default is Y.|
|ESF SIGNON ALLOWED||Specifies whether the Extended Submit Facility is to be supported for this node by IBM Connect:Direct. The DTF identified in this record must support ESF in order to sign on in ESF mode using IBM Connect:Direct. The default is N.|
|MAXIMUM WORKER SUBTASKS||Specifies the maximum number of WSTs (worker subtasks) to be used for this node. Define one WST per parallel session defined for this node. Do not exceed the MAX TASKS value in the Control Record with the total number of worker subtasks defined for all DTF NODE records in the system. The default is 2.|
|ENTRIES IN WORK QUEUE||Specifies the maximum number of actual requests to be allowed on the pending work queue for this node. An excessive value here could result in an inordinate response time for terminal users. During installation, the default is the MAXIMUM WORKER SUBTASKS specification.|
|OUTPUT RECORD LIMIT||Specifies the upper limit on the number of lines of output that are accepted in response to a SELECT PROCESS or SELECT STATISTICS command. Output from these commands is stored in CICS temporary storage until viewed or explicitly deleted. The default is a limit of 800 80-byte records.|
|SLOW RESPONSE NOTIFICATION||Contains the time interval, expressed as minutes and seconds, after which IBM Connect:Direct notifies you of potential problems with slow response. This is a 4-character field. The default is 0200 (2 minutes).|
