THAW SERVER
THAW SERVER
This command allows link managers such as LINKMON processes, TCP processes, and
LCS processes to resume sending requests to server processes in a frozen server class.
server-class
specifies the name of a previously defined and added SERVER object.
GROUP group-name
specifies the name of a set of SERVER objects, each configured as a member of the
specified group. The THAW SERVER command is issued to each SERVER
associated with this group.
*
issues the THAW SERVER command to all SERVER objects in a given
Pathway/XM environment.
Considerations
•
After successful completion of this command, the PATHMON process allows
Pathsend requesters access to the thawed server classes. For SCREEN COBOL
requesters without an ON ERROR clause, the TCP resumes the operation by
executing the send request. (When SCREEN COBOL requesters containing an ON
ERROR clause encounter a frozen server class, they perform as directed by the ON
ERROR code.)
•
For an application using TCPs, the TCP performs the following after the THAW
command resumes the activity of a terminal that was in TMF transaction mode:
1. Directs the TMF software to restart the transaction at the BEGIN-
TRANSACTION statement and to assign a new transaction identifier
2. Increments the special register RESTART-COUNTER by 1
•
Unlike the TCP, the LINKMON process does not call any TMF procedures or
increment any special TMF registers. It is the responsibility of the Pathsend
requesters to detect any errors (by an error code) and proceed as required by the
application.
Example
The following command restarts communication with all the frozen server classes in the
SALES group:
THAW SERVER GROUP SALES
THAW SERVER { server-class }
{ GROUP group-name }
{ * }
