Kevin,

This is great! Can we get a list of all the OIDs that Oracle uses? Can you also let the group know if any additional plug-ins are required for Perl to work with SNMP?

Yes. You can use PERL to do such things such as getting the database state, name, consistent gets, system block gets, etc from SNMP:

#!/usr/local/bin/perl

use BER;

use SNMP_Session;
use SNMP_util;
use Getopt::Std;

getopts("h:i:");

my($host, $community, $response, $bindings, $binding, $value, @oid, @retvals);
my $session;

$host = $opt_h;
$community = "public";
$db_index = $opt_i;

# Database State
$oid[0] = '.1.3.6.1.2.1.39.1.9.1.1.2.2';
#Database Name
$oid[1] = '.1.3.6.1.2.1.39.1.7.1.4.' . $db_index .

'.7.100.98.95.110.97.109.101.1'; # Consistent Block Gets
$oid[2] = 'enterprises.111.4.1.1.1.2.' . $db_index;
# System Block Gets
$oid[3] = 'enterprises.111.4.1.1.1.4.' . $db_index;

my @retvals = SNMP_util::snmpget ( $host, @oid );

Thanks Dennis, Gary

I have tools at my disposal to monitor the db, and I have no problem with that. I was just reading through snmp and was intrigues by the idea that I could get some information without running scripts through sqlplus interface and if so how to accomplish that.

I know it is doable because IA does that, just wondering if it would be feasible to do it be some scripting ...

Raj - I'm no expert on SNMP, so maybe someone that is more knowledgeable will reply. I believe that SNMP underlies most of the monitoring tools on the market today. OEM may even use SNMP. I can see two approaches for you.

You write your own tool that will issue SNMP alerts. Perhaps this would be a Unix daemon process that executes database queries, and then based on what it finds, issues SNMP alerts.
Use an existing tool to accomplish what you want.

If your desire is to create a database monitoring tool that you can give away for free, then sell to CA for a lot of money, take path #1. If your goal is to become a better DBA, then I would go with #2.

Has anyone implemented basic DB monitoring using snmp MIB information rather

than running queries against the db?

I am looking into this and have no clue or available docs on how to do this (esp on AIX). If someone can point me to the right direction, I would really

appreciate that.

TIA
