splserver()

Description:

Start or stop an SPL process on the current machine.

When cfg is present, the function starts SPL process; when it is absent, the function stops the process. Below is content of the XML configuration file:

<?xml version="1.0" encoding="UTF-8"?>

<SERVER>

// esProc root directory

<SplHome>D:/raqsoft </SplHome>

<JVMArgs>-Xms128m -Xmx1024m</JVMArgs>

// temp file timeout (hour)

<TempTimeOut>12</TempTimeOut>

// Check timeout interval (second)

<Interval>0</Interval>

// Proxy timeout (hour)

<ProxyTimeOut>12</ProxyTimeOut>

// Log file path

<LogPath>D:/raqsoft/esProc/log/splserverlog</LogPath>

// Path of esProc configuration file raqsoftConfig.xml

  <SplConfig>D:/raqsoft/esProc/config/raqsoftConfig.xml</SplConfig>

</SERVER>

Name and path of the configuration file can be user-defined; just make sure that the reference in parameter cfg is the same

Parameter:

port	The port number.
cfg	XML configuration file name; stop the process at the specified port when it is absent.

Below is content of test.splx:

	A	B
1	=connect("demo").query("select * from SCORES  where SUBJECT=?",arg1)
2	return A1	return A1.(SCORE)

 

 

	A
1	=splserver(8281,"D:/SplServer.xml")	Start the process at port number 8281 on the current machine.
2	=callx("test.splx",["English","Math","PE"];["127.0.0.1:8281"])	Allocate task to node 127.0.0.1:8281 to execute the spl script.
3	=splserver(8281)	Stop the process at port number 8281 on the current machine.
