Hi, PERL Script: 
#!usr/bin/perl -w 
use strict;
use warnings;

my $c=`ps -ef |grep -v grep|grep pmon|sed -e 's/.*_//'|sort -u >dbname
+.log`; 
my $cnt=`ps -ef |grep -v grep|grep pmon|sed -e 's/.*_//'|sort -u |awk 
+'END {print NR-0}'`; 

my $i=1; 
while($i<=$cnt) {
    my $dbn=`awk 'NR==$i' dbname.log`; 
    my $dbname = trim($dbn); 
    my $p=`cat /etc/oratab |grep $dbname|grep -v "#"|gawk -F: '{print 
+\$2'}`;
    $ENV{'ORACLE_SID'}="$dbname"; 
    $ENV{'ORACLE_HOME'}="$p"; 
    $path1="$ENV{ ORACLE_HOME}/bin"
    open(my $fh, '|-', 'sqlplus "/as sysdba"') or die "$!";
    print $fh "select name from v\$database;\nexit;\n";
    close($fh);
    $i++;
} 
exit 0; 

sub trim { 
    my $s = shift;
    $s =~s/^\s+|\s+$//g; 
    return $s; 
}

the given result is unable to set path, because "sqlplus" in ORACLE_HOME/bin so i need to include it in PATH.
