Configuration Option
|
Description
|
---|---|
DMSERVER/SOAP/DATA_SVC/IDLE_TIMEOUT
|
Specifies the number
of seconds to allow a DFWSVC process to remain idle before it is terminated.
The default setting is 0 indicating that there is no time-out. Negative
values are ignored.
|
DMSERVER/SOAP/DATA_SVC/QUEUE
|
Specifies whether to
queue real-time data service requests. The value YES indicates that
if all DFWSVC process are busy and no new process are allowed to start,
then service requests are placed in a queue. The requests are submitted
to DFWSVC processes as processes become available. The default value
NO returns an error to the requesting client when the preceding conditions
apply.
|
DMSERVER/SOAP/DATA_SVC/MAX_NUM
|
Specifies the maximum number of real-time data services that the SOAP server is allowed
to run simultaneously. The default value is 10. If a new service
request would exceed the set limit, and if the request queue is not enabled, then
an error message is sent to the requesting client. This option applies to the SOAP
server, meaning that the service requests are coming from a SOAP client. It does
not apply to the WLP server or requests coming from a WLP client.
|
DMSERVER/WLP/DATA_SVC/MAX_NUM
|
Specifies the maximum number of real-time data services that the WLP server is allowed
to run simultaneously. The default value is 10. If a new service request exceeds this
limit, an error message is returned to the requesting client. This option applies
to the WLP server, which processes service requests from WLP clients. This option
does not apply to the SOAP server or requests from SOAP clients.
|
DMSERVER/SOAP/DATA_SVC/JOB_COUNT_MIN
|
Specifies the minimum
number of instances of a given real-time data service that remain
loaded. When the number of jobs reaches the minimum limit, the DataFlux
Data Management Server halts the unloading of instances of the specified
job. The value of this option is of the form min-count:service-file-name.
The option value syntax
can include one or more blank-separated instances of count:name-of-service.
Note: A whitespace character (' ')
is used as a separator between potentially multiple entries. Therefore,
the pathname of the services used in this option cannot contain whitespace
characters.
|
DMSERVER/SOAP/DATA_SVC/JOB_COUNT_MAX
|
Specifies the maximum
number of instances of a given real-time data service job that can
be loaded at the same time. When this limit is reached, the DataFlux
Data Management Server will not load any more instances of that service
job. The value of this option is of the form
max-count:service-file-name .
The option value syntax
can include one or more blank-separated instances of count:name-of-service.
Note: A whitespace character (' ')
is used as a separator between potentially multiple entries. Therefore,
the pathname of the services used in this option cannot contain whitespace
characters.
|
DMSERVER/SOAP/DATA_SVC/MAX_ERRS
|
Specifies the maximum
number of service errors that can occur in a DFWSVC process before
the process is terminated. The default value is -1, which indicates
that there is no process termination due to service errors.
|
DMSERVER/SOAP/DATA_SVC/MAX_REQUESTS
|
Specifies the maximum
number of service requests that a DFWSVC is allowed to handle before
it is terminated. The default value is -1, which indicates that processes
are not terminated based on the number of service requests received.
|
DMSERVER/SOAP/DATA_SVC/MAX_RUNTIME
|
Specifies the number of seconds to allow a real-time data service to produce output
data or an error. If a data service does not produce a response within the specified
number of seconds, the server terminates the corresponding DFWSVC process. The server
then sends a SOAP fault message to the client. The default value for this option is
0 (zero), which
indicates that a real-time data service can run indefinitely. Negative values are
ignored. Note that the actual time to terminate the process can differ from the value
of this option because fractional values are rounded up. An option value of 1.5 can
result in a physical duration of 2 seconds before the service is terminated.
|
install-path/etc/service.cfg
.
When you set these configurations, consider that similar configuration
options in the DataFlux Data Management Server’s app.cfg configuration
file are also applied. The options in app.cfg are applied first, before
the configuration options are applied from service.cfg.
Configuration Option

Description
|
---|---|
DATASVC/IGNORE_DECLARED_VARS
|
The value YES causes
DFWSVC to ignore all input and output variables that are declared
in the real-time data service. Use this value to run real-time data
services that were created prior to DataFlux Data Management Server
2.2. All input macros are passed into the data service and all final
macro values are returned to the client along with the output data.
The default value NO
causes DFWSVC to allow in only the input variables that are declared
on the job. If any other input variables are passed in, the real-time
data service terminates and returns an error to the client. Only the
output variables declared on the job will be returned along with the
output data from the service.
|
DATASVC/THREAD_STACK_SIZE
|
This option sets the
stack size, in bytes, for each thread of DFWSVC in the UNIX and Linux
operating environments. The default value is 1MB. This option is ignored
in the Windows operating environment.
|
DATASVC/MAX_OUTPUT_BYTES
|
This option controls the maximum amount of data, in bytes, that the DFWSVC process
is allowed to return to the SOAP client. The default value is 128MB (134217728 bytes).
If the output data exceeds
the limit, the real-time data service is terminated. The error message Output data size
limit exceeded is logged in the log files of DFWSVC
and DataFlux Data Management Server. The SOAP client also receives
the error message. A value of 0 or less disables the examination of
the output data size.
Note: This option applies only
when DFWSVC is invoked by a SOAP client request. The option is ignored
when DFWSVC is invoked by a WLP client request.
