iQuery.getSysName and other GETxxx UTF Published by: Bob Cozzi on 14 Jun 2019 view comments

Retrieve System Information UDF

The various iQuery.GETxxx() UDF return system information as a varchar or integer value.

UDF Return Type Description
GETCPUCOUNT integer Returns the number of CPU CORES installed on the system.
GETCURLIB varchar(10) Returns the current library from the library list.
GETSRLNBR varchar(10) Returns the System Serial Number. Similar to RTVSYSVAL SYSVAL(QSRLNBR)
GETSYSNAME varchar(10) Returns the System Name. Similar to RTVNETA SYSNAME(&SYSNAME)
GETENV varchar(32739) Returns the value of an Environment Variable

With the exception of GETENV(), these UDFs have no input parameter.

GETENV() Parameters

Parameter Type Description
Environment Variable Name varchar(256) The name of the environment variable whose value is to be returned.

The GETENV() UTF runs the getenv() API to return the environment value. This API is case-sensitive, therefore the iQuery GETENV() UDF input value is also case sensitive. getenv('java_Home') is not the same as getenv('JAVA_HOME').

The following examples assume the host variables are already declared unless SQL iQuery Script is being used, in which case host variables are auto-created.

Example

values iQuery.getCPUcount() INTO :cores;
values iQuery.getCurLib() INTO :myCURLIB;
values iQuery.getSRLNBR() INTO :SRLNBR;
values iQuery.getSysName() INTO :SysName;
values iQuery.getEnv('JAVA_HOME') INTO :classPath;
