######################################### # Process Monitor Config File Parameters. ######################################### ################ WARNING ############### # It is strongly advised not to make any # changes to these configurations, as unexpected results may occur. # Any changes to these configurations should occur only as directed in # documentation that originates from Safe Software, or from Safe technical # support. Any changes made to this file do not take effect unless # NODE_OVERWRITE is set to TRUE. ################ WARNING ############### # # The Process Monitor program is started from the command line and takes one argument. # This argument is the pathname of the configuration parameter file. # # Configuration parameters are used to set various operating characteristics # of the Process Monitor. Values for these parameters are read in from this file # when the Process Monitor is started. This configuration parameter file is an # ASCII text file containing one parameter assignment on each line. Each # assignment consists of a parameter name followed by an equal-sign followed # by the parameter's value. # # For example, the line: # # NODE_ADMIN_PORT=7500 # # assigns the "NODE_ADMIN_PORT" parameter a value of "7500". # # The Process Monitor is case-sensitive to parameter names. Blank lines and lines # beginning with the "#" character are treated as comments and are ignored. # # Changes to any parameter value in this file will take effect only upon # subsequent restart of the Process Monitor. # # The following parameters must be present in the config file and named exactly # as shown: # #-------------------------------------- # Log File #-------------------------------------- # # LOG_CONFIG_PATH - The folder path that contains the log file configuration. # # LOG_FILE_NAME - The path name of the message log file. # #-------------------------------------- # Engine Failover #-------------------------------------- # # FAILOVER_ENGINE_AUTOCONNECT - If true, then Engines will switch to active core when a failover occurs. If false, # then Engines will not switch to the new active core when a failover occurs. If failover # is not enabled in the Core configuration then there is no Engine switching. # #-------------------------------------- # Node Management #-------------------------------------- # # NODE_ADMIN_PORT - TCP/IP port number on which to listen for requests # # NODE_NAME - The name used by this FME Server node to identify itself. If no value is assigned, the node takes # the host name of the system on which it is running. # # NODE_DESCRIPTION - The string used by this FME Server node to describe itself. If no value is assigned, the node's # description is the empty string. # # NODE_HOST - The host name of the system on which it is running. # # NODE_ENGINE_ADMIN_PORT - The Engine administration port used to manage ENGINE processes. # # NODE_OVERWRITE - If "true" then process configurations specified in this file will always overwrite those # already specified in the database. If "false" or missing, the process configurations will # only be added when the node hasn't already been added part of deployment. # # FME Engines can be added or removed from nodes. New Engine process configurations are defined by # Engine templates which specify the START, STOP and PARAMS commands. # # TEMPLATE_START_ENGINE=<startcommand> # TEMPLATE_STOP_ENGINE=<stopcommand> # TEMPLATE_PARAMS_ENGINE=<optionalparams> # # To prevent duplications, process configurations may reference Engine template start commands as # macros by wrapping parameters with ! characters. # # For example: # START_ENGINE_Engine1=!TEMPLATE_START_ENGINE! # STOP_ENGINE_Engine1=!TEMPLATE_STOP_ENGINE! # PARAMS_ENGINE_Engine1=!TEMPLATE_PARAMS_ENGINE! # # Process Configuration # --------------------- # # The next parameters are those that define the actual commands that the Process Monitor should # start in a separate process and monitor. The format for these command parameters is: # # START_<processtype>_<processname>=<startcommand> # STOP_<processtype>_<processname>=<stopcommand> # PARAMS_<processtype>_<processname>=[log=<boolean>]|[attempts=<integer>]|[norestart=<integer>]|[wait=<integer>]|[continual=<integer>] # # Where <processtype> has one of the following syntaxes: # # ENGINE - An FME Engine process # SYSTEM - A FME System process # # Where <procesname> is the unique name of the process. # # Here is an example START command: # # START_ENGINE_Engine1=/FMEServer/Server/fme/fme.exe REGISTER_SOCKET JIM 7070 # # When the Process Monitor encounters this parameter, it starts a new FME Engine process, runs the # command string in the process and monitors the process for termination. # If/when the process terminates, the Process Monitor creates another process and re-runs the same command # string again. The Process Monitor continues this behaviour until it reaches its restart attempt limit. # # Optional START Parameters: # # "-ENGINE_HOST_NAME" specifies the host name the Engine is started on. This is used to group Engines for distributed systems. # On single Engine host environments, this can be "localhost" otherwise it should be the Engine host name. # # # STOP # # Each process START command can have an optional STOP parameter defining a # custom stop command which will be run to shut down the process. # For example: # # START_SYSTEM_Core=... # STOP_SYSTEM_Core=... # # PARAMS # # Each process START command can also have an optional parameters. Parameters are delimited by |. # For example: # # PARAMS_SYSTEM_Core=log=true|attempts=20|wait=0|continual=60 # # Optional Parameters: # # "log" # # If "true" the process output generated by the command will be logged to the message log file. If "false", # its process output is not logged to the log file. If missing, SYSTEM processes will default to "false" # while ENGINE processes will default to "true". # # When process output is logged, each output line will be prefixed by the command's <processname> string. # This helps to identify which process command generated each output line. # # # For example the following would explicitly enable process output logging for this ENGINE configuration # and the resulting outlines from this process would be prefixed by "Engine1": # # START_ENGINE_Engine1=/FMEServer/Server/fme/fme.exe REGISTER_SOCKET JIM 7070 # PARAMS_ENGINE_Engine1=log=true # # "norestart" # # The status value returned to the Process Monitor by the monitored process when the latter # terminates. If a start command string specifies a value for this parameter, then # if the monitored process terminates and returns the specified status value to # the Process Monitor, the latter WILL NOT restart the terminated process. If # this parameter is absent, or it is present but the terminating process # returns a status value different from the specified value, the Process Monitor # WILL restart the terminated process. If this parameter value is present but specifies an # invalid integer value, the Process Monitor ignores any return values from the process. # # "attempts" # # The number of times the Process Monitor will attempt to start the process to be monitored. If the maximum # value is reached the Process Monitor will give up attempting to start the process. If this flag # is absent or is present and specifies a value <= 0, the process will have no limit to the number of # times it is restarted. If this suffix flag is present and specifies an invalid integer value then # the default start attempt limit value of 20 is used. # # Here is an example start command line using the "norestart" parameter (specifying a return status value of 27), # the "log" parameter and the "attempts" parameter described above: # # START_ENGINE_Engine1=/FMEServer/Server/fme/fme REGISTER_SOCKET JIM 7070 # PARAMS_ENGINE_Engine1=log=true|norestart=27|attempts=20 # # "continual" # # The number of seconds the Process Monitor will wait before attempting to start the process to be monitored. # If this suffix flag is present and specified a value >= 0, the process will be restarted continually with # a delay of <n> seconds between restart attempts. If this suffix flag is absent or is present and specifies # a value <= -1, the process will not be continually restarted. Note: The delay to <n> seconds will start at # 1 second and increase 1 second with each delay till it reaches a delay of <n> seconds upon which it will # continue to have a delay of <n> seconds. # # "wait" # # For each process the Process Monitor interprets the wait period specified by # the "wait" parameter in one of two ways: # # 1) Monitor Port Directive is Present # # If the -MONITOR_PORT directive is present in the process START command line, # the wait period represents the maximum number of seconds the Process Monitor # will wait for the monitored process to signal (via the monitor port) that it has # successfully started. # # If the signal is received before the wait period expires, the Process Monitor # immediately proceeds to start the next process. # # If the signal has not been received by the time the wait period expires, the # Process Monitor stops waiting at that point and proceeds to start the next # process. # # If the process fails to start after reaching its startup attempt limit # (as specified by the "attempts" suffix flag), the Process Monitor # immediately proceeds to start the next process, even if the wait period # has not yet expired. # # To cause the Process Monitor to wait indefinitely for the start signal, specify # a WAIT value of zero. # # # 2) Monitor Port Directive is Absent # # If the -MONITOR_PORT directive is absent from the process START command line, # the wait period represents the number of seconds the Process Monitor waits before # continuing on to start the next process. # # If the process fails to start after reaching its startup attempt limit # (as specified by the "attempts" suffix flag), the Process Monitor # immediately proceeds to start the next process, even if the wait period # has not yet expired. # # Specifying a waut value of zero causes the Process Monitor to immediately start # the next process without waiting. # # # In both of the above cases 1) and 2), if no "wait" parameter is specified for a # process, the Process Monitor uses the default time value (in seconds) of zero. # # Processes that support the optional "MONITOR_PORT" directive" can include the # following in their START command: # # -MONITOR_PORT <portNum> # # This directive specifies the TCP/IP port on which the Process Monitor listens for a # startup completed message from the process. Upon successful startup completion the process # should connect to this port and send the message string "STARTED". No further communication occurs. # # If the directive specifies a <portNum> value of zero then a free port number is dynamically # determined by the Process Monitor at runtime. This is the usual case. If the <portNum> value is specified as # non-zero and positive then that literal port number is used. # # If the process does not implement the monitor port capability then the # directive should be omitted from the command string. # #-------------------------------------------------------------------------- ################ WARNING ############### # It is strongly advised not to make any # changes to these configurations, as unexpected results may occur. # Any changes to these configurations should occur only as directed in # documentation that originates from Safe Software, or from Safe technical # support.
