[Harbour] HBNETIO - Production Application Usage

Subject: [Harbour] HBNETIO - Production Application Usage

Hello Everybody

Here is what I did to test my flagship application "Vouch"
under HBNETIO protocol concurrently with same system where
data resides, on LAN connected terminals with/without NETIO,
on real-time WEB-IP, and everything worked extremely fine.
The only issue worth reporting is the speed on WEB-IP
whic was 8 times slower than stand-alone and about
5 times slower than LAN.

ULTIMATELY - results were so satisfying that my clients
were noticeably impressed. And the credit goes to, PRZEMEK.
Thanks, you did a splendid job.

For WEB-IP we tested with this scenario:

1. Forwarded a port, #63000, on our wireless router.
2. Obtained a domain, vouch.dynalias.com, from DynDNS.com
3. Updated its IP with our server's IP.
4. Executed netiosrv.exe with  63000  192.168.1.108  c:\creative.v15
5. From the terminals invoked "Vouch.exe" with parameters
"vouch.dynalias.com" and "63000" through Vouch.ini.
6. Executed "Vouch.exe" as regular application as before from other
terminals and from same server station.

VOILA all went fine. One terminal employed was from out of the country.

All data updates, concurrent, were ok. All locks respected.

A big leap forward.

[Harbour] HBNETIO - A Case Study by Pritpal Bedi

CCH : From the Harbour Developers List

Date: Mon, 7 Sep 2009 13:29:16 -0700 (PDT)

Hello All

Here are the steps I took to convert my flagship application "Vouch" ( a mini ERP solutions for a variety of verticals ) to honor HBNETIO lib along-with normal execution as ususal.

BACKDROP

I use configuration file vouch.ini to set various parameters of the application, which beside setting extended protocols, sets the data paths too. So at any given point of execution every table/index/other file always contain fully qualified path.

This principal I adopted and implemented in my applications always made my efforts to switch to different RDD's which a minimum efforts and changes in the source code. Even mixing different RDDs for different parts of the application are made possible and been used successfully.

A table when used has this format:
  c:\creative.ram\checks.dbf  [ index: c:\creative.ram\checks.z01 ]
  ^^^^^^^^^^                                   ROOT FOLDER
                        ^^^^^^^                   TABLE
       =>
  net:checks.dbf

  c:\creative.ram\cac00001\vpn453za.dbf
  c:\creative.ram\caccomon\defaults.dbf   , etc
  ^^^^^^^^^^                                   ROOT FOLDER
                        ^^^^^^^                    AREA OF OPERATION
                                        ^^^^^^^    TABLE NAME
       =>
  net:caccomon\defaults.dbf

For HBNETIO protocol I just changed the root data path of any
supported file [ .dbf | .z01 (CDX) ] [ which must reside on the
data server ] with "net:" and that's it.

I executed the netiosrv.exe as:
  c:\creative.acp\netio\netiosrv.exe  63000  0.0.0.0  c:\creative.ram

And included in vouch.exe:

  #if 1   /* Net IO Client-Server Protocol */
     IF INIVLW( "NetIOEnabled" )
        cNetIOServer := IniValue( 'NetIOServer' )
        cNetIOPort   := IniValue( 'NetIOPort'   )
        IF !empty( cNetIOServer ) .and. !empty( cNetIOPort )
           lSuccess  := netio_connect( cNetIOServer, val( cNetIOPort ) )
           uiDebug( "netio_connect()", lSuccess, cNetIOServer, cNetIOPort )
           uiDebug( " " )
        ENDIF
     ENDIF
  #endif

IniValue() parses the vouch.ini and keeps in static variable and
supplies a value as requested.

The other functions which I adjusted to change the root
folder to "net:" looks like this:

Function VouExistTable( cAlias, cFile, cPath, cDriver, lTemp )
  Local lRet := .f.

  DEFAULT lTemp TO .f.

  cFile := UPPER( trim( cFile ) )
  if right( cFile,4 ) == '.DBF'
     cFile := substr( cFile, 1, len( cFile )-4 )
  endif

  do case

  case lTemp
     lRet := file( cPath +'\'+ cFile + '.DBF' )

  case cDriver == 'SQLRDD'
     lRet := VouIsFile( cFile )

  case cDriver == 'CACHERDD'
     #ifdef __CACHE__
     lRet := CacheExistTable( cFile )
     #endif

  otherwise
     IF Vou_IsNetIO()
        IF right( cPath, 1 ) == ":"
           cFile := cPath + cFile + '.DBF'
        ELSE
           cFile := cPath +'\'+ cFile + '.DBF'
        ENDIF
     ELSE
        cFile := cPath +'\'+ cFile + '.DBF'
     ENDIF
     lRet := DbExists( cFile )

  endcase

  Return lRet

//----------------------------------------------------------------------//

Function VouExistIndex( cAlias, cFile, cPath, cDriver, lTemp )
  Local lRet := .f.

  DEFAULT lTemp TO .f.

  cFile := UPPER( trim( cFile ) )
  if right( cFile,4 ) == '.Z01'
     cFile := substr( cFile, 1, len( cFile )-4 )
  endif

  do case

  case lTemp
     lRet := file( cPath +'\'+ cFile + '.Z01' )

  case cDriver == 'SQLRDD'
     lRet := VouIsFile( cFile,.t. )

  case cDriver == 'CACHERDD'
     #ifdef __CACHE__
     lRet := CacheExistIndex( cFile )
     #endif

  otherwise
     IF Vou_IsNetIO()
        IF right( cPath, 1 ) == ":"
           cFile := cPath + cFile + '.Z01'
        ELSE
           cFile := cPath +'\'+ cFile + '.Z01'
        ENDIF
     ELSE
        cFile := cPath +'\'+ cFile + '.Z01'
     ENDIF
     lRet := DbExists( cFile )

  endcase

  Return lRet

//----------------------------------------------------------------------//

FUNCTION Vou_IsNetIO()

  IF INIVLW( 'NetIOEnabled' )
     RETURN .t.
  ENDIF

  RETURN .f.

/*----------------------------------------------------------------------*/

FUNCTION Get_Path( cAlias )
  LOCAL cPath, p

  IF !empty( p := get_d_attr( cAlias,D_PATH ) )
     cPath := eval( COMPILE( p ) )
  ELSE
     cPath := setWPath()
  ENDIF

  IF get_d_attr( cAlias, D_FILE_TYPE ) <> 9  /* Vouch Specific and on the
Client */
     cPath := Vou_AdjustPathToNetIO( cPath )
  ENDIF

  RETURN cPath

/*----------------------------------------------------------------------*/

FUNCTION Vou_AdjustPathToNetIO( cPath )
  LOCAL n, cPathL

  IF Vou_IsNetIO()
     cPathL := lower( cPath )
     IF left( cPathL, 4 ) != "net:"
        n := at( 'creative.',  cPathL )
        IF n > 0  // And it must be
           cPath := "net:" + substr( cPath, n + 13 )
        ENDIF
     ENDIF
  ENDIF

  RETURN cPath

//----------------------------------------------------------------------//


NOTE: the above code is a case study only and should not
        be used as is. However you may adopt the similar approach if
        you want to.


OTHER CHANGES YOU MAY REQUIRE
==========================
  You may also need to swich to following changes which work in both modes.

  FILE()       =>   DBEXISTS()
  FERASE()   =>   DBDROP()

THE OBSERVATION
==============
  netiosrv.prg

//------------------------------//
proc main( cPort, cServer, cRoot )
  local pListenSocket

  if empty( cPort )
     cPort := '63000'
  endif

  pListenSocket := netio_mtserver( val( cPort ), cServer, cRoot )

  if empty( pListenSocket )
     ? "Cannot start server."
  else
     wait "Press any key to stop NETIO server."
     netio_serverstop( pListenSocket )
     pListenSocket := NIL
  endif

  return
//------------------------------//

  netiosrv.prg => hbmk2 netiosrv.hbp => netiosrv.exe

  * Consumes very little memory footprint : 2.5 MB
  * Consumes very little CPU time even if many instances are logged : 3-5%
  * With each instance increase in memory : 16 KB
  * Reduces 16 kb with every instance if quits or is killed
  * Record|File locks a released instantlt if an instance holding them is
killed.

THE EXPECTATIONS
===============
  Would been nice if root path be automatically stripped
  if "net:" is found a part of the table name, i.e.,
     net:c:\creative.ram\cac00001\mytable.dbf
        =>
     net:cac00001\mytable.dbf
         where
     c:\creative.ram == netiosrv's root path

THE RESULTS
==========
  Amazing.
  Przemek, accept my hats off to this contribution.

  BUT it will be really heartening if you decide to finish NETRDD.
  The community is looking at NETRDD desperately.

Pritpal Bedi
