SNMP Solstice Master agent

Hi All,
I have a Subagent that talks with SNMP Solstice Master Agent on solaris 8. For the set requests sent by the Command line or Manager the Master Agent breaks the PDU into multiple set requests and then sends them one by one(with 1 variable at a time) to my Subagent.How can I avoid this break up of PDU at SNMP Master agent.
Thanks
Priya

Hello:
I created exactly as you specified. I.e weblogic.reg, weblogic.rsrc, weblogic.acl. But the issue I have is My weblogic snmp agent is listening on port 8061. Snmp demon on 161. So when I request the Snmp demon with OID of weblogic object. I am not getting the result also call is not reaching weblogic agent. Instead I am getting no such name or OID. So I am wondering why snmp demon is not forwarding the request to snmp demon.
Also Could you please explain the execution sequence of snmp demon and where you think I need to look at. Also please explain the constructs used in reg/acl/rsrc files.
Note:
I am using wls 6.1 sp2. So just my starting admin server. The enabled snmp gets started. Also I configured snmp demon so that when ever it gets started the weblogic server also starts. Also there is no issue in receiving traps.
Thanks in Advance.

Re: Wls agent as subagent to Sun's Snmp Master Agent

I have successfully configured the WL SNMP agent as subagent to
Sun's (Solaris 7 in my case) master SNMP agent.
Sun's Solstice Enterprise Agent documentation under docs.sun.com
is a bit confusing but serves as a reference if not a step-by-step guide.
Here are the general steps that I took:
1) Modify the shipped startSNMPAgent.sh for your system password
and community (I wouldn't use "public"!).
Add some if-then-fi code to check for the $1 command line parameter,
so Sun's master agent can pass in the dynamically allocated port number
that the agent will listen to. I also changed the ownership of this
script so only root can see it, as it contains the WL admin password.
2) Go to the /etc/snmp/conf directory (default Solaris 7 install).
Create the files weblogic.rsrc and weblogic.reg using the mibiisa.*
files as templates.
3) In the weblogic.reg file, add the lines
"macros = { bea = enterprise.140 }" before the "agents" line.
This defines the weblogic agent's starting OID point.
Then, change the subtree line to "bea".
4) In the .rsrc file, change the command used to spawn the
agent to "/weblogic/startSNMPAgent.sh $PORT".
Be aware that this spawn command is visible through Sun's master
agent MIB, so don't put anything sensitive in there (like a
community name or password).
5) Finally, there is a timing condition that you should be aware of.
WebLogic's SNMP agent will only bind to an active WL server.
Sun's master agent will only bind to an active subagent.
Therefore, you should ensure that
WebLogic server is started first (and the server comes completely
up), then Sun's master agent is started. I setup my /etc/rc3.d
startup files to run weblogic before snmpdx. I had to insert a
sleep command to make sure that WL was completely up before
snmpdx was run. This is because my startup script runs java in
the background, so if you don't sleep then WL won't be up before
snmpdx spawns the subagent and tries to bind to it.
Finally, Sun's mib files can be found under /var/snmp/mib.
Easier to find than NT's mib files!
Hope that helps -

Hi Sanjeev
My Wls agent is working fine as Master agent with Sun's Snmpdx as subagentto it.
There is no problem with that.
But can I make WLS agent, subagent to Sun's Snmp Agent.For that I needWls
SubAgent resource
files to be included in the configuration directory of Sun's Snmp Agent.The last time i checked, Sun's master agent is more "loosely coupled"
with
other agents it needs to co-ordinate with. I haven't tried it, however
i
beleive it should work. Because the master agent doesn't rely on built-in
protocol for interaction with other agents. (much like -otherAgents option
in the wls agent).
You just need to specify in SUN's syntax (resource files...) where the
wls
agent is running, what is its community, which MIBs it supports , what
should be the timeout and such ...
Good Luck!
If you run into any problem let me know.
Is this possible in the first place and if so how do I do it. I sawyour
response on the same issue for
Windows NT. I am mailing to find out if its different on Solaris(orUnix).

SNMP subagent with SMUX SNMP master agent

I'm looking for the smux agent configuration for ucp-snmp to be able to use it as the master agent on a Linux/Solaris server. The subagent would be the LDAP instance snmp sub-agent. According to the documentation, if I have a master agent that I can't get rid of and is smux compliant, I can use it instead of the Netscape SNMP Master agent.
Even by configuring the ucp-snmp master agent as per the Netscape Directory Server documentation, the subagent is not starting. I always get the following error: "Unexpected error" in the console 4.2 window.
I'm using a Netscape Directory Server 4.16
Can anybody help me on what should be the smux configuration and then how to start the LDAP instance subagent?

Hi,
Iplanet does not support for it's products being installed on linux or snmp for linux.

Snmp master agent won't start

I'm using Web Server 7.0U1 on Solaris 10U4. I'm trying to start the SNMP master subagent. On my Linux test platform, this works fine. But on the Solaris host, 'magt' hangs forever at startup and does nothing. This happens both when using the web console and wadm start-snmp-master-agent command.
How do I make magt work?

The SNMP master agent fails to start on Solaris 10U2 (and higher) due to the TCP fusion feature added in Solaris 10U2. (TCP fusion is a protocol-less data path for loopback TCP connections). One of the possible workarounds for this issue is to disable TCP fusion by adding the following line in /etc/system:
set ip:do_tcp_fusion = 0x0
The Sun Info Doc 86046 available on sunsolve explains the various TCP fusion related tunables.

Dbsnmp unable to connect to SNMP master agent

NMS-00001: Warning: dbsnmp unable to connect to SNMP master agent
I get the above message as dbsnmp.log every day in my testdb.. wat is the purpose and meaning
oracle_home\network\log

Hmmmmm.
Using the online error code lookup facility in the Oracle documentation, I see the following:
NMS-00001: Warning: service unable to connect to SNMP master agent.
Cause: An SNMP Master Agent is used to communicate with a third party SNMP monitoring console. The specified service could not contact the SNMP master agent. The master agent supported by Oracle for this platform is not installed, or has not been started. Messages specific to this platform follow.
This is a warning and does not prevent the agent from communicating with the console. If Oracle Enterprise Manager is the only monitoring console accessing this agent, the NMS-00001 error can be considered informational and should be ignored. Configuration of the SNMP Master Agent is not reguired for the Oracle Enterprise Manager Console.
Action: Consult Oracle documentation for your platform; then, make sure that the correct SNMP master agent is installed and started. The SNMP Master Agent and the Oracle Intelligent Agent must be configured correctly before the Oracle Intelligent Agent can communicate over SNMP to the Master Agent.
The Oracle Intelligent Agent needs to be configured. The 7.3.2.x agent required an SNMP.ORA file. All later versions of the Oracle Intelligent Agent are self-configuring and do not reguire the creation of an snmp.ora file.
Solution Explanation
1. The Oracle Intelligent Agent needs to be configured. The 7.3.2.x agent required an SNMP.ORA file. All later versions of the Oracle Intelligent Agent are self-configuring and do not reguire the creation of an snmp.ora file.
2. The SNMP Master Agent needs to be configured and started.
There is even more. Especially in the are of 'how to configure and start'. Can wee look that up for you as well?

Dialog between the SNMP Master Agent and a SNMP SubAgent

I have developped a SNMP SubAgent. The Master Agent uses the static method to register the SubAgent. In the Registration File of the SubAgent, I have specified the UDP port number (example: port = 1234). When the SubAgent is started (by the MasterAgent), it must open the UDP port specified in the Registration File. The dialog works fine between the SubAgent and the Master Agent.
I would prefer not to specify the UDP port number in the Registration File so that the Master Agent chooses itself a free UDP port number. But the SubAgent needs to know this UDP port number to dialog with the Master Agent. I thought the SubAgent could read it in the Status File of the Master Agent. BUT in fact, when the Master Agent invokes the SubAgent, its Status File isn't yet updated with the right port number value.
How may the SubAgent know the UDP port number chosen by the Master Agent ?
NB: I haven't use the SunOS SNMP toolkit to develop the SubAgent.

Hi ,
Good question.
The subagent only communicates via the port 161 with the master agent as per my understanding. It only listens for SNMP request on the port number mentioned in the <<agentname>>.rsrc file or the port assigned by the master agent. Please start the subgent with no options "-d 4" and then you can confirm the behaviour. Enclosed below is a snippet of that output for reference. Also the UserGuide at the following link will be helpful.

Ports used for Intelligent agent and snmp master agent

I could not find any documentation regarding which ports are used for communication between master and intelligent
agent. Moreover which port has to be mentioned if I use snmpget for the master agent. Please let me also know if I use a
management platform like CA-Unicenter with which port I have to send the traps and where to configure.
Thanks

Solstice enterprise agent and Sun Mgmt Center

Is anyone familiar with a way to convert a sub-agent developed with Solstice Enterprise Agent and APIs into a Sun Management Center sub-agent? I have a MIB as well as source code for the stubbed code generated by mibcodegen. ... Not sure if this is totally useless at this point and I have to start from scratch.

The MIB files are located under /var/snmp/mib , as for the OID i can't remember.. but if i remember i can check some old documents which i should have somewhere (unless someone else manages to answer first ;-)
As to the snmpwalk problem, ensure that you have the latest patches, i recall there being a snmpwalk <-> EA bug. It might have been in Solaris 9, but it might also have been in an earlier release.
Anyway, the latest Enterprise Agent patches are always good for security reasons.

SNMP v2 compatible agent and system resources

Hi everybody,
I have to provide an SNMP v2 compatible agent (which provides answers to SNMP v2c requests) providing some system resources like cpu consumption, hard disk consumption and disk free space and some specific values through a private MIB.
I have tried to implement a SNMP subagent using the Solaris Enterprise Agents SDK (taking the demo as reference), but contrary with was I thoght, it can not answer when the manager is asking using protocol version 2 (I am some confused, becouse I read that there is no many changes between version 1 and 2c and requests should be compatible).
Additionally, I could not find the MIB where the Solaris sub-agent is providing the requested values (cpu consumption, hard disk consumption and disk free space).
Is there any way to solve this problem? Using maybe the Solaris Enterprise Manager or the Solaris Manager Center? Are they provided with the Solaris version 9 OS?
Thank you very much in advance.
Best regards,
Carlos

I bought a tvee 30 last month and had the same problem. I opened a ticket with BA and below is the fun thread on this subject. If you scroll to the bottom, you get to read the fun part about sending the unit back in the future for a firmware upgrade....
Customer via Web: 01/02/2012 04:10 PM I have a tvee 30 and I am not able to get it working with any Apple device in my house. I read about the problem with IOS5 and I am anxiously waiting for either BA or Apple to step up and fix this. Seems like a bunch of finger pointing going on right now. Anyway, I have the same problem with an Imac running 10.6.8 Would you expect the same IOS5 problem to affect the Imac?
Response BA Customer Service & Suport via Email 01/05/2012 06:56 AM We are currently working on a firmware upgrade that will address Apple products being that the AD2P system that came with the iOS5 upgrade is the issue not letting the two units connect.
Customer via Web 01/05/2012 07:56 AM Could you estimate when this firmware upgrade will be available? I am trying to decide if I should return the unit because Apple bluetooth connectivity was one of the primary reasons why I bought it. Tnanks
Response BA Customer Service & Suport via Email 01/05/2012 08:27 AM I believe the firmware upgrade will be available within a month or so, and it will correct the issue you are having.
Customer via Web 01/05/2012 09:06 AM how does one get informed about a firmware upgrade availability and how does one implement this on the tvee 30? I don't recall see any sort of USB or other port on the unit where one could install it. thanks
Response BA Customer Service & Suport via Email 01/05/2012 09:49 AM The announcement will be posted on the FAQ's link of the site. The unit will need to be sent in to be upgraded.

Change Master Agent for Cluster-Based Agent -- OEM 11.1.0.1

        We had a 6 node RAC cluster and a cluster-based management agent installed to monitor.
        Node 6 was the Master agent.
       Now node 6 is not part of the cluster.
    I am getting metric collection for the cluster.
I cluster configuration in OEM shows Master agent as node 6. I only have 3 nodes now.
How do I update the master agent or the cluster.
Thanks,
Silver

On the clustef homepage in OEM there is a link called properties under the name of the cluster. Click the link it will shlw the true master node. What I have seen in the pasf what can rsolve the issue is bounce the agent on that master node. You can also try a clear state. You can also use the configuration for the cluster database to make sure the old instance has been remove from OEM.

SNMP oracle intelligent agent configuration

Hi,
i have a Linux installation with Orcale 8 DB and an intelligent

I would like to monitor the database via OEM and
try to plan jobs etc.
I have problems to discover for services inside OEM (NT-Side)
I got the error Failed to find node address"
Who can shortly explain what must be configured.
Or has somebody configuration Files which will work ?

You mast start the intelligent Agent on the LINUX Box
lsnrctl dbsnmp_start
During the FIRST Startup the Agent generates its config files
(snmp_ro.ora,snmp_rw.ora) itselve....
You should complete your network configuration (LISTENER.ORA,
TNSNAMES.ORA and ORATAB (all in lower case within unix)) befor
starting the Agent the first time...

Why snmpdemo always stop after invoked by Master agent?

(1) I have useed "mibcodegen" to generate a code sample from "mib_demo.txt" which is in SUNWconn/sea/snmp/sample ;
(2) I have never modify any code except "Makefile"
(3) I use make to build a "snmpdemod" and reset snmpdemo.reg , snmpdemo.acl, snmpdemo.rsrc and snmpdemo.snmprelay;
(4) Then I run command as follow:
# ./snmpdx -y -c /etc/snmp/conf
# ps -ef | grep snmp
root 4401 1 0 09:10:08 pts/3 0:00 snmpdemod -p 8041 -i 4
root 4399 1 0 09:10:03 pts/3 0:00 ./snmpdx -y -c /etc/snmp/conf
(5) But after a moment ,snmpdemod had stopped .
Question:
(1) To be a daemon snmp subagent ,do I have to modify "agent_loop" in snmpdemo_appl.c ?
(2) Who could give me a code sample about "daemon"
I come from China , so I could not get more information about solaris,please help me .
Thanks in advance.

I have resolve this problem by install all patches of SEA

Solstice integration with JMX

Hello,
We want to try and implement some SNMP sub Agents using JMX.
But there is something that I don't understand:
Can I still use Solstice Master agent and register JMX sub Agents with it, because I don't want to implement mib-2.system and stuff like this within my JMX agents...
Am I missing something ??...
Can somebody recommend a JMX adapter that is working with Solstice Master agent ?
Any info will be appreciated !
Thanks !!
Yashik.

Hello,
You're not going to be able to do this (easily) by trying to integrate the DLL into an ActiveX control that is used in the browser. I believe (I could be wrong on this) that using it via an ActiveX control would not give you sufficiently low level enough access for the driver to work (it's been a while since I delved into the world of ActiveX controls, so like I say I could be wrong on that one).
However, I would tend to split this problem into 2 pieces -
1) Use the supplied DLL in the way it was intended, i.e. use it on the PC that has the weighing machine attached to it. You would then need to write some code (Delphi code perhaps) to read the weighing machine data and insert it into your Oracle database.
2) Design an APEX application that gives you a view onto that data in the Oracle database.
Hope this helps,
John.

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.

Carles

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.
