You can use Config::Simple since the parameters you have given seems like configuration items,
have Globalconf.conf as below

[ConnectionSettings]
Server_name = "server";
User_name = "user";
Password = "password";

[ExeFiles]
Srvr_mngr = 'C:\Siebel\WebClient\Bin\srvrmgr.exe';
List_of_Values = 'C:\Siebel\WebClient\Bin\LOV.bat';

[Others]
Row_id = "Session id";
[download]

In main program

use Config::Simple;
my $Config = {};

Config::Simple->import_from("Globalconf.conf",$Config);

print $Config->{"ConnectionSettings.Server_name"};

print $Config->{"ConnectionSettings.Password"};

print $Config->{"Others.Row_id"};
[download]

Output:
server password Session id
