Object Types

All commands and responses contain an object-type token in the header. For the

Pathway subsystem, object types are identified in programs by symbolic names of the

form ZPWY-OBJ-name, where name identifies the object type. For example, the TCP

object type is represented by the name ZPWY-OBJ-TCP. The object-type header

token, ZSPI-TKN-OBJECT-TYPE, always has one of these names.

For Pathway/iTS commands, the Pathway subsystem supports the programmatic

objects listed in Table 3-3.

Table 3-2. TS/MP Commands Affecting Pathway/iTS Objects

TS/MP Command Meaning

ZPWY-CMD-FREEZE

Prohibits all link managers (such as LINKMON

processes or TCPs) from sending requests to a

server class if the object is not active

ZPWY-CMD-SHUTDOWN2 Stops TERM and TCP objects during the Pathway

subsystem shutdown process

ZPWY-CMD-THAW

Allows link managers (such as LINKMON processes

and TCPs) to send to the server class

Table 3-3. Pathway/iTS Object Types (page1of2)

Object Type Description

TCP Objects

ZPWY-OBJ-TCP A definition for a terminal control process (TCP) that interprets

and executes SCREEN COBOL programs. TCPs coordinate

communication among SCREEN COBOL programs, the

associated I/O devices or processes, and the server processes.

ZPWY-OBJ-TCPLINK A link between a TCP and a specific server process in a server

class.

ZPWY-OBJ-TCPSC A server class linked to a TCP. This object type is used with the

STATS command and ZPWY-VAL-ALLSC to obtain statistics

on all server classes that have links to a single TCP.

ZPWY-OBJ-SCTCP A TCP linked to a server class.

TERM Objects
