G The nodes that make up a cluster are define by the below parameter. If D left blank the system is queried to identify all the nodes that are attached to the current cluster.

Q F.4 Channel controls
E This system works in client/server fashion. The foreground interface F either DCL, MCL or DECwindows sends all I/O and other requests to the C server process via a mailbox. The server process then performs the B request or forwards the request onto the target node (if a remote H system was indicated). The maximum number of RMS file channels that are B used by the server process is controlled by these parameters. The C channels are only opened as needed and closed when not needed. Any H request for a channel that occurs after all channels are busy is queued ? up and performed when a channel becomes free. On a very active A scheduling system these numbers may need to be increased. If you ; greatly increase these values the /FILE_LIMIT value in the 6 SCHEDULE_START.COM procedure may need to be increased.

S F.5 Network controls
G All requests that reference a remote node (either via a node specified D in submit parameter, explicitly in an initiate or prerequisite list H element, or from a foreground command) are transmitted to that node for D processing. The access on the remote node by the requesting user is F determined by equating the incoming user to one on the remote node by E reading the NETPROXY.DAT file. All the standard proxy specifications G are honored. If no local information is found the request is rejected. G By specifying a DEFAULT_USER the request is not rejected but given the C access associated with this DEFAULT_USER. Setting the DISABLE flag H indicates that the remote user has the same access rights on the remote : system as on the source system (this is usually not true).

T F.6 Resource polling
< Certain resources and events (file availability, disk space E availability and delayed job) are all detected by a polling process. G Periodically the system checks to see if the event has occurred. These 5 parameters control the interval between these checks.
