当我尝试连接到Oracle 11g时,为什么Perl的DBI会抱怨"失败:错误OCIEnNN创建"？

Question

我使用简单的Perl脚本连接到Oracle 11g数据库时出现以下错误:

 failed: ERROR OCIEnvNlsCreate. Check ORACLE_HOME (Linux) env var  or PATH (Windows) and or NLS settings, permissions, etc. at

脚本如下:

#!/usr/local/bin/perl

use strict;
use DBI;

if ($#ARGV < 3) {
print "Usage: perl testDbAccess.pl dataBaseUser dataBasePassword SID dataBasePort\n";
exit 0;
}
my ($user, $pwd, $sid, $port) = @ARGV;

my $host = `hostname`;
my $dbh;
my $sth;
my $dbname = "dbi:Oracle:HOST=$host;SID=$sid;PORT=$port";

openDbConnection();
closeDbConnection();

sub openDbConnection() {
        $dbh = DBI->connect ($dbname, $user ,$pwd , { RaiseError => 1}) || die "Database connection not made: $DBI::errstr";
}

sub closeDbConnection() {
        #$sth->finish();
        $dbh->disconnect();
}

以前有人见过这个问题吗？

检查Oracle客户端配置(包括,如消息所示,ORACLE_HOME),检查文件权限等.DBI本身不太可能与问题有关,我知道DBD :: Oracle与之兼容的事实11g库(至少11g InstantClient).
