Cluster Server 7.4.2 Configuration Guide for SAP Web Application Server - Windows

To configure SAPWebAS preonline script

1. Go to the %VCS_HOME%\bin\Trigger directory.
2. Skip this step if the preonline file exists in this directory.

   If the preonline file does not exist, copy the sample preonline trigger file from the %VCS_HOME%\bin\Sample_Triggers directory to the %VCS_HOME%\bin\Triggers directory, rename the file to preonline, and then use this file.

3. Add the following lines to the preonline file:

   #--------------------------------------------------------------
   # Start sapwebas preonline trigger.
   #--------------------------------------------------------------
   # Perl preonline.pl <system> <group> <whyonlining> 
   <systemwheregroupfaulted>
   my $system = $ARGV[0];
   my $group = $ARGV[1];
   my $whyonlining = $ARGV[2];
   my $systemwheregroupfaulted = undef;
   my $sArgs = join(' ', @ARGV);
   VCSAG_LOG_MSG("I", "Arguments [$sArgs]", 15041);
   if(defined $ARGV[3]) {
   	$systemwheregroupfaulted = $ARGV[3];
   }
   my $SAPWebASPreOnlineTrigger = sprintf("%s\\bin\\SAPWebAS\\
   sapwebaspreonline.exe", $vcs_home);
   VCSAG_LOG_MSG("I", 
   "The trigger command is [$SAPPreOnlineTrigger]", 15041);
   if(defined $systemwheregroupfaulted)
   {
   	VCSAG_LOG_MSG("I", "The group is faulted on syetem =
   [$systemwheregroupfaulted]", 15042);
   	$CMD = sprintf("\"%s\" %s %s %s %s", $SAPWebASPreOnlineTrigger,
   	$system, $group, $whyonlining, $systemwheregroupfaulted);
   }
   else {
   	$CMD = sprintf("\"%s\" %s %s %s", $SAPWebASPreOnlineTrigger, 
    $system, $group, $whyonlining);
   }
   system($CMD);
   my $exit_value = $? >> 8;
   VCSAG_LOG_MSG("I", "The exit code from the trigger: [$exit_value].",
    15046, $exit_value);
   if($exit_value == 0) {
   	VCSAG_LOG_MSG("I", "The PreOnline Trigger for SAP executed 
   successfully.", 15046);
   	exit;
   }
   elsif($exit_value == 1) {
   	VCSAG_LOG_MSG("I", "The PreOnline Trigger for SAP FAILED.", 15047);
   	exit;
   }
   else {
   	VCSAG_LOG_MSG("I", "Unknown PreOnline trigger.", 15048);
   }
   #--------------------------------------------------------------
   # End sapwebas preonline trigger.
   #--------------------------------------------------------------
   .
   .
   # give control back to HAD.
   if (defined $ARGV[3]) {
   	'\"$vcs_home\\bin\\hagrp\" -online -nopre $ARGV[1] -sys $ARGV[0] 
   -checkpartial $ARGV[3]';
   	exit;
   }
   
   '\"$vcs_home\\bin\\hagrp\" -online -nopre $ARGV[1] -sys $ARGV[0]';
   exit;
   
   

4. Use the following command to set the preonline trigger attribute to true for the Service Groups to which the Enqueue and Enqueue Replication server instances belongs:

   C:\> hagrp -modify service_group PreOnline 1 -sys system
