The table below lists and describes the parameters that can be specified and their default values. For details about the parameters, see 8.7.2 Details of the parameters in the query group property file.

Table 8-5 Specifiable parameters and their default values (query group property file)

No.	Parameter name	Description	Default value	Permitted value range	Whether or not changeable during restart^#1

2	querygroup.sleepOnOverStore	Specifies the period of time that execution of the query group is to be placed in the sleep mode when the SDP server's checking determines that there is no available space in the output stream queue.	Value specified in system_config.properties^#2	1 to 2147483647	Y
3	querygroup.sleepOnOverStoreRetryCount	Specifies the number of times the SDP server is to check the output stream queue for available space before it loads to the output stream queue the tuples obtained from query execution.	Value specified in system_config.properties^#2	0 to 2147483647	Y
4	stream.filterCondition	Specifies a conditional expression for using the timestamp adjustment function to filter tuples.	None	See 8.7.2(4) stream.filterCondition=conditional-expression.	Y
5	stream.filterMode	Specifies whether the timestamp adjustment function is to be used to filter tuples: unuse: Does not filter tuples. condition: Filters tuples.	unuse	unuse or condition	Y
6	stream.freeInputQueueSizeThreshold	Specifies a threshold value (%) for the available size with respect to the maximum number of elements used in the input stream queue.	Value specified in system_config.properties^#2	Integer from 1 to 99	Y
7	stream.freeInputQueueSizeThresholdOutputMessage	Specifies whether a warning message is to be output to the SDP server's message log: true: Outputs warning message. false: Does not output warning message.	Value specified in system_config.properties^#2	true or false	Y
8	stream.maxKeepTupleCount	Specifies the maximum number of tuples that can be retained by the timestamp adjustment function.	Value specified in system_config.properties^#2	Integer from 1 to 1048576	Y
9	stream.propertyFiles	Specifies the names of the stream property files when properties are specified for individual streams.	None	--	Y
10	stream.timestampAccuracy	Specifies the time units and time adjustment range for the timestamp adjustment function.	Value specified in system_config.properties^#2	See 8.7.2(10) stream.timestampAccuracy={{sec\|msec\|usec},time-adjustment-range\|unuse}.	Y
11	stream.timestampMode	Specifies the timestamp mode used to timestamp tuples: Server: Uses the server mode. DataSource: Uses the data source mode.	Value specified in system_config.properties^#2	Server or DataSource	N
12	stream.timestampPosition	Specifies the name of the time-data column in tuples.	Value specified in system_config.properties^#2	--	Y
13	stream.tupleLogMode	Specifies whether execution of the sdptplput command is to be enabled: true: sdptplput command is to be executed. false: Execution of sdptplput command is to be disabled.	Value specified in system_config.properties^#2	true or false	N
14	tpl.backupFileCount	Specifies the maximum number of backup generations to be retained for the tuple log file.	Value specified in system_config.properties^#2	Integer from 0 to 10	Y
15	tpl.bufferCount	Specifies the number of tuple log buffers.	Value specified in system_config.properties^#2	Integer from 3 to 512	Y
16	tpl.bufferSize	Specifies the maximum size of a tuple log buffer (in kilobytes).	Value specified in system_config.properties^#2	Integer from 1 to 2048000	Y
17	tpl.fileCount	Specifies the maximum number of tuple log files.	Value specified in system_config.properties^#2	Integer from 3 to 512	Y
18	tpl.fileSize	Specifies the maximum size of a tuple log file (in megabytes).	Value specified in system_config.properties^#2	Integer from 1 to 2048	Y
19	tpl.outputLevel	Specifies the tuple log output level: 1: Outputs tuple logs for the tuples that are stored in the stream queue. 2: Outputs tuple logs for the tuples that are discarded due to out-of-sequence time. 3: Outputs tuple logs for tuples with levels 1 and 2.	Value specified in system_config.properties^#2	Integer from 1 to 3	Y
20	tpl.outputTrigger	Specifies the tuple log file output timing: BUFFER: Outputs tuple logs to a file when the buffer being used to collect the current tuple logs in the target stream becomes full. NONE: Does not output tuple logs to a file or perform buffering of tuple logs.	Value specified in system_config.properties^#2	BUFFER or NONE	Y
21	tpl.useOverwrite	Specifies whether the buffer is to be overwritten in the event of a full tuple log buffer: true: Overwrites the tuple log buffer. false: Does not overwrite the tuple log buffer.	Value specified in system_config.properties^#2	true or false	Y

Legend:: Y: Changeable; N: Not changeable; --: Not applicable

#1: Indicates whether (Y) or not (N) the parameter's setting can be changed when the query group is started by the sdpcqlstart command with the -reload option specified.

#2: If no value is specified in the system configuration property file (system_config.properties), the default value for the system configuration property file is used.
