Object Types
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
