|
* Sccsid: @(#)config.h 2.1.8.2
|
||
|
|
*
|
||
|
|
* this file allows the compilation of DBGEN to be tailored to specific
|
||
|
|
* architectures and operating systems. Some options are grouped
|
||
|
|
* together to allow easier compilation on a given vendor's hardware.
|
||
|
|
*
|
||
|
|
* The following #defines will effect the code:
|
||
|
|
* TPCH -- make will create TPCH (set in makefile)
|
||
|
|
* TPCR -- make will create TPCR (set in makefile)
|
||
|
|
* KILL(pid) -- how to terminate a process in a parallel load
|
||
|
|
* SPAWN -- name of system call to clone an existing process
|
||
|
|
* SET_HANDLER(proc) -- name of routine to handle signals in parallel load
|
||
|
|
* WAIT(res, pid) -- how to await the termination of a child
|
||
|
|
* SEPARATOR -- character used to separate fields in flat files
|
||
|
|
* DBNAME -- default name of database to be loaded
|
||
|
|
* STDLIB_HAS_GETOPT -- to prevent confilcts with gloabal getopt()
|
||
|
|
* MDY_DATE -- generate dates as MM-DD-YY
|
||
|
|
* WIN32 -- support for WindowsNT
|
||
|
|
* SUPPORT_64BITS -- compiler defines a 64 bit datatype
|
||
|
|
* DSS_HUGE -- 64 bit data type
|
||
|
|
* HUGE_FORMAT -- printf string for 64 bit data type
|
||
|
|
* HUGE_COUNT -- number of objects in DSS_HUGE
|
||
|
|
* EOL_HANDLING -- flat files don't need final column separator
|
||
|
|
*
|
||
|
|
* OS defines
|
||
|
|
* ==========
|
||
|
|
* ATT -- getopt() handling
|
||
|
|
* DIGITAL -- changes for DigUnix 64-bit support
|
||
|
|
* DOS -- disable all multi-user functionality/dependency
|
||
|
|
* HP -- posix source inclusion differences
|
||
|
|
* IBM -- posix source inclusion differences
|
||
|
|
* ICL -- getopt() handling
|
||
|
|
* MVS -- special handling of varchar format
|
||
|
|
* SGI -- getopt() handling
|
||
|
|
* SUN -- getopt() handling
|
||
|
|
* TANDEM -- EOL handling
|
||
|
|
* U2200 -- death of parent kills children automatically
|
||
|
|
* VMS -- signal/fork handing differences
|
||
|
|
*
|
||
|
|
* Database defines
|
||
|
|
* ================
|
||
|
|
* DB2 -- use DB2 dialect in QGEN
|
||
|
|
* INFORMIX -- use Informix dialect in QGEN
|
||
|
|
* SQLSERVER -- use SQLSERVER dialect in QGEN
|
||
|
|
* SYBASE -- use Sybase dialect in QGEN
|
||
|
|
* TDAT -- use Teradata dialect in QGEN
