WLS SNMP Agent questions ?

1- What version of SNMP does the WLS SNMP agent use ?
( IMO, it is the SNMPv2)
2-Is it possible to use the WLS SNMP Agent to register our own MBean ? ( is
there a Factory , or an entry in JNDI ? )
3- In the case, I develop my own JMX Agent, is this agent clusterable ? or
should I have several JMX Agent running , with Dynamic MBeans( because we
don't know on which machine in the cluster a MBean is ) ?

[Q] WLS SNMP Agent questions?

Hello, all
I am attaching the weblogic.properties, startWebLogic.cmd and
startSNMPAgent.cmd
I started the weblogic server 5.1 on port 7001.
Then started the SNMP agent using the command
"%JAVA% weblogic.SNMPAgent -password system -snmpPort 161 -serverURLs
t3://210.182.160.120:7001 -community public -debugLevel 3 -trapDestinations
210.182.160.111:162".
210.182.160.120 : WebLogic Server 5.1
210.182.160.111 : Trinity(NMS)
Then I tried to access the "serverState" variable using the command
"java snmpgetnext localhost .1.3.6.1.4.1.140.600.20.1.20"
"java snmpgetwalk localhost .1.3.6.1.4.1.140.600.20"
But i am getting the following error.
Response PDU received from localhost/127.0.0.1, community: public
Error in response. There is no such variable name in this MIB.
Index: 1
Errored Object ID: .1.3.6.1.4.1.140.600.40.1.10
How can I solve this problem?
Thanks in advance...
Have the pretty day. ^^;

Hello,
way back we had the same problem and the reason was, that the path
names with the server instances were to long
(/opt/wlsroot/wlsInstances/axsExpert.SwissAir/S_243_7001 ->
/opt/wlsroot/wlsInstances/axsExpert.SAir/S_243_7001). But this was
with WLS 5.1 SP8.

Hello Michel,
Thanks for the reply. As you may have noticed, that the SNMP agents which are
already running, the owner is <root>. These services are required and I do not
have or I can not obtain the password to start/stop the same. As such, the only
option which I have is to start the weblogic-specific SNMP service in a different
port. Question: In the parameters, I specified : <snmpPort 1600 trace Destinations
1601> I am still getting the same error. What else is required and/or how do I
proceed to start the same service?
Thanks for your help beforehand,

How to configure SNMP agent for Oracle 10g

Hello,
I've installed oracle 10g in a Windows 2000 SP4 and I want to monitor database using SNMP.
I've already installed Windows SNMP agent but I haven't any idea how to configure Oracle in order to grant SNMP monitoring.
What should I do?
Is Oracle database ready to be monitored via SNMP by default?
Thanks in advance for your help.

Hello,
Thanks for your message.
In fact, I already found this doc in oracle, but it just show executables I have to install and my question can I install these executables.
I've already installed Windows SNMP agent, configured and testedwith disk space checkings, but it doesn't work fine with Oracle.
I launched Oracle Universal Installer and I checked Installed Products, but I haven't found how to install SNMP agents for oracle.
How can I add Oracle Peer Master Agent and Encapsulator to my oracle installation?
Thanks again for your help.

Weblogic SNMP Agent with WindowsNT SNMP Agent

Can I setup Weblogic SNMP agent as a sub-agent to Windows NT SNMP agent (Microsoft's version)? According to documentation, sub-agents for Microsft's SNMP agent need to be implemented as 32-bit multithreaded DLLs using the Microsoft SNMP API. Does Weblogic have DLLs that we could use for this purpose?
If that is not possible, is there a roadmap on how to provide the same support as the Microsoft's SNMP agent under Weblogic SNMP agent so that the Weblogic agent would provide the same visibility into the system that the Microsoft's agent does by default? Is this even possible?
Thanks.

"Sanjeev Mishra" <[email protected]> wrote:

Does anyone know how to make Microsoft's SNMP Master Agent run on a different port?
I figured this out. It uses the 'snmp' setting from the services file. Just changing that works. Would have been more convenient if there was also a command line flag for that purpose.
Thanks.

No.
However, you can have the WLS agent proxy for the NT agent. e.g. you can run
the NT agent on a non-standard port and the WLS agent on 161 and then use
'-otherAgents' option so that the WLS agent will forward any reqs for the NT
agent MIB to that agent. In this setup the SNMP Manager can view that node
as one SNMP entity which supports the WLS MIB + NT MIB
See http://www.weblogic.com/docs51/admindocs/snmpagent.html#use_agent for
details.

How to use SNMP Agent

Hi All,
Can anybody tell me how to use SNMP Agent to monitor the Access and Identity Servers

Hi Ramesh,
I cannot comment on WebLogic & SNMP - this kind of questions would
probably need to be asked on a WebLogic forum.
If you're looking for an SNMP Manager API though, you may want to have a
look at the Java Dynamic Management Kit (commercial product,
free evaluation):

Hope this helps,

Does SNMP agent on the admin server polls managed objects automatically?

Hi All,
If I enable SNMP agent on the admin server, does it mean that it polls and caches MIB of all the managed servers in the domain and return it if a client requests for information or it polls and caches that MIB value only when requested?
2)Suppose a client requests for SNMP data of a managed instance and the instance is down, does admin server keep polling or does it timeout after a number of secs or retries. I don't see any config params in weblogic 8.1.3 or weblogic 9.0 console.
Thanks. I appreciate your answers.
Thanks,

Are you saying the notes are incorrect?
No, I wasn't commenting on that at all. I was just saying that DBUA is the recommended way of upgrading databases... and that's in spades if you're talking about 100GB databases.
I'll lay odds that DBUA to 10.2.0.1 and then patching to 10.2.0.3 is quicker than exporting and importing 100GB of data.
(Applying a 10.2.0.3 patch is done with opatch and doesn't require a fresh installation of Oracle. A patch mostly just modifies the data dictionary: it's finished in minutes, not hours).
My real point: these sorts of questions are incredibly easy to ask, answer, discard, re-ask, modify, mull over and basically experiment with in a virtual environment.
And again: it's utterly bizarre why you wouldn't have physical access to this database (and keep in mind that I can't keep in mind little nuggets of information such as this one which you didn't see fit to share earlier!)
It's in a virtual server. Virtual servers can be zipped up and emailed! (OK, maybe not 100GB... but I've shipped a small hard disk in a zip-lok pack envelope half way round the world before now -though obviously it wasn't critical to have the contents of that envelope available for use all the time... Still, it sounds to me like here's a technology (virtualisation) that's not being properly exploited).

Jdmk _ snmp agent acl

Hi,
I'm using jdmk snmp adaptor to develop an snmp agent. I've a problem in setting the agent accessControl List. In particular I've this accessListFile (jdmk.acl):
acl = {
communities = public
access = read-only
managers = <myIpAddress> }
and in my Agent, I set acl as follow:
SnmpAdaptorServer snmpAdaptor = null;
JdmkAcl theAcl = (JdmkAcl)(snmpAdaptor.getInetAddressAcl());
theAcl.setAuthorizedListFile("myAclPath"+jdmk.acl");
theAcl.rereadTheFile();
No Exception has been raised, but I can access my agent via snmp from various address and with a community different from "public". So It's seems that my acl file doesn't work properly
thank in advance
l

Hi,
You should use a constructor that takes an InetAddressAcl instead:
SnmpAdaptorServer(InetAddressAcl acl, int port);
Simply create the acl in this way:
String aclFileName = .... ;
InetAddressAcl acl = new JdmkAcl("myACL", aclFileName);
int port = ... ;
SnmpAdaptorServer server = new SnmpAdaptorServer(acl,port);
I believe this should work. The point here is that the adaptor has a mode where if you
don't specify any ACL, and the default ACL file doesn't exists, then it will let anybody
connect. If however, you do specify an ACL, then only those hosts/communities specified
in the ACL will be authorized - and if the file doesn't exists, nobody will.
Note: you can also ask any question regarding Java DMK on project OpenDMK user's list:

Hope this helps,

SNMP Agent for Solaris

We're looking for a direction regarding an SNMP agent for our Solaris Platforms. The standard agent bundled with Solaris seems to have many issues and CERT outstanding advisories. I'm wondering what others out there are running, Net-SNMP?, the ESD agent bundled with Sun Management Center?, others? I've looked at the ESD agent and it looks as though this would provide Temps, Fan Speeds, etc... for our servers but it seems as though it's lacking things like 1/5/15 minute load averages, CPU/Disk utilization etc...
Any experiences are welcome!

hi,
The same problem with me too. Im using Net-SNMP, but may be one cant trust its reliability and even if we use Net-SNMP loading of PERL scripts/modules is difficult in solaris.
If you got /gathered any useful information please let me too know.

How do I restart the SNMP agents with the original command line options?

I'm creating an application that changes the SNMP trap target configuration files and then restarts the SNMP agent. I'm currently working with the mibiisa agent. I want to make sure that I restart the service with the new trap targets but with the original command line options. How can I restart the mibiisa service with the same command line options that it originally loaded with?

It is not "Network Time" that is the problem, but actually "SystemStarter." SystemStarter is an interim kludge to enable the work or the old StartupItems until they can be converted to LaunchDaemons or LaunchAgents controlled by launchd. Launcd calls SystemStarter to launch all the unconverted StartupItems. ntpd is now under the control of launchd directly.
Launchctl is the command to load and unload the plist files, but I don't think it has a mechanism to restart a daemon.
There are start and stop commands in launchctl, but the man page indicates that they are for debugging purposes.
I also imagine you could just kill the ntp daemon and let it restart with new settings. It is most likely set to "keepAlive" so that it will automatically restart.

SNMP Agent in Oracle 11.2g

Hello all
I wanted to use SNMP agent in Oracle 11.2g, but I read that this agent is deprecated from the Oracle 11G. I also read in a thread that Oracle will continue the support till 2018. Which one is true??
If I can't use SNMP agent what is your suggestion for its substitution?? Can I use Oracle Management Agent??
My Os : Microsoft Server 2000
Thatnk you alll

Oracle recommends to stop using SNMP going forward. Though the extended support for SNMP will be valid until Jan 2018 (Refer Metalink 1341834.1) .
The reason is not clearly given. They have mentioned that from oracle database 12 cloud control onwards , SNMP is completely removed. Probably that is the reason.
It might be okay to use it, until your environment gets upgraded to oracle 12c.

Disable SNMP agent in Job Server

SNMP agent was enabled in job server. Since it is enabled, we cannot access windows SNMP agent. Windows SNMP and DS SNMP is using the same ports 161. We have an application which shows all the statistics of all the servers, but for DS server it not showing all the statistics.
So we are planning to disable the SNMP agent in job server. Is there any implications if i disable the SNMP agent?
DS Version 4.0

It should not create any issues.
