accept mode (Digital UNIX)
If accept mode is immediate, then Session Control will automatically accept the connection before activating the end user. If accept mode is deferred, then it is up to the program to accept or reject the connection.
Default: Immediate Value: Immediate or deferred addresses
A set of end-user specifications, any one of which, when specified in the destination name field of an incoming connection request, causes applications defined by this entity to be invoked.
Default: Empty set Value: Set of end-user specifications allow decnet-internet gateway access (Digital UNIX)
If true, this application supports gateway access. If the user name supplied by the incoming connect request contains a @ or !, the application spawner starts up the application under the session control DECnet-Internet Gateway user.
Default: False Value: True or false client
Identifies the name of the local user that will be activated upon receipt of a connect request containing a destination name matching one of the values in the destination names attribute.
Default: None Value: Entity name data abstraction (Digital UNIX)
Type of data transfer interface the application will be using: message type or stream type. The message data abstraction is identical to the sequenced-packet socket concept of the Phase IV session control. When writing applications, you should use the same data abstraction as that used by the program to which you connect.
Default: Message Value: Message or stream Table 22-1 compares message and stream data abstractions.
Table 22-1 Data Abstraction Type Comparison Message Type Stream Type Preserves message boundaries Does not preserve message boundaries OpenVMS default abstraction Commonly used for Digital UNIX applications Not available on TCP/IP Available on TCP/IP Supported by XTI Supported by XTI image name
File name of a program to be invoked upon receipt of a connection request containing an address that matches one of the values contained in the set described by the addresses characteristic.
Default: No image name Value: File specification incoming alias (OpenVMS)
Specifies how a particular application responds to incoming connect requests directed to the alias node address. If false, the application does not allow a specified application to receive incoming connect requests that have been directed to the alias node address.incoming osi tsel (OpenVMS)
A TSEL is a string of hexadecimal digits, and the length of that string should be an even number between 2 and 64, inclusive.The TSEL this image will accept connections for. This is similar to the destination names attribute. However, applications using this access point for in-connection matching do not use DNA Session Control Protocol.
incoming proxy
Specifies whether to honor incoming proxy requests. If this attribute is set to false, requests to invoke proxies on incoming requests are ignored. The setting of this characteristic overrides the setting of the session control incoming proxy characteristic for the specified application.
Default: True Value: True or false maximum instances (Digital UNIX)
Maximum number of simultaneous instances of this application allowed. If a connect request comes in for this application while the maximum number of instances exist, the connect request will be rejected with ObjectTooBusy. A value of 0 indicates no maximum.
Default: 0 Value: None network priority (OpenVMS)
When operating over Connectionless Network Service (CLNS), indicates network priority encoded in the NPDU (network protocol data unit) header for all transmitted packets. It can be used by intermediate systems to assign the packets to queues of appropriate priority.
Default: 0 Value: 0--225 node synonym
Default form in which the remote node name is passed to the application.
Default: False Value: True or false
false The full node name is used. true The node synonym is used; if no synonym is available, the full name is used. outgoing alias (OpenVMS)
Specifies whether a particular object uses the alias node identifier in its outgoing connect requests. If false, the specified object is not allowed to use the alias node address in its outgoing connect requests.
Default: True Value: True or false outgoing proxy (OpenVMS)
Default action to execute when user does not explicitly specify whether or not to invoke a proxy.
Default: True Value: True or false programming interface (Digital UNIX)
Programming interface used by the DECnet application (socket interface).
Default: Phase IV Value: Phase IV or Phase V user name
Identifies the default account under which the application is to run. For OpenVMS, if null then system defaults are used to select the user.
Default: None Value: Latin1String
