TS/MP 2.5 System Management Manual

Considerations
• If you are using Pathway/iTS, consider these:
Unless ! is specified, the freeze does not take effect until all SCREEN COBOL STOP-MODE
special registers have a value of zero and no server in the server class has incomplete
◦
or outstanding requests. In the interim, the server class is put into the FREEZE-PENDING
state.
◦ If a SCREEN COBOL requestor attempts to send a request to a frozen server class and
the SEND statement is coded without an ON ERROR clause, these occurs:
◦ If the terminal is not in TMF transaction mode, the terminal pauses until the server class
is thawed.
◦ If the terminal is in TMF transaction mode, the terminal pauses and the TMF subsystem
backs out the current transaction. After the THAW command resumes terminal activity, the
TCP directs the TMF software to restart the transaction at the BEGIN-TRANSACTION verb
and to assign a new transaction identifier, and increments the special register
RESTARTCOUNTER by 1.
If the SEND statement is coded with an ON ERROR clause, the TCP passes control to the
screen program for the appropriate action.
• Unlike a TCP, the ACS subsystem processes do not call any TMF procedures or increment any
special TMF registers. It is the responsibility of the Pathsend process to detect any errors (by
an error code) and proceed as required by the application.
Examples
These commands freeze the specified server classes:
FREEZE SERVER CLASS-1
FREEZE (CLASS-2,CLASS-3) !
This command immediately freezes all the server classes in the Pathway environment:
FREEZE SERVER * !
This command freezes all the server classes in the system and waits until all terminals are frozen
to complete the command:
FREEZE SERVER *, WAIT
INFO SERVER Command
Use the INFO SERVER command to display the attribute values defined in the PATHMON
configuration file for a server class.
INFO [ / OUT list-file / ]
{ [ SERVER ] server-class }
{ [ SERVER ] ( server-class [ , server-class ] ...) }
{ SERVER * }
[ , OBEYFORM ]
OUT list-file
directs output to the named list file; this can be a DEFINE name. If this option is omitted, the
PATHMON process directs the output to the PATHCOM list file; this is typically the home terminal.
server-class
specifies the name of a previously defined and added SERVER object.
