Automatic Discovery of Nodes

Hello,
I installed the 10g agent on a host successufully. 10g OEM on another server did not discover the node automatically. I can manaually discover new nodes? Thank you in advance.

on the agent side ...
emctl status agent
see what url its talking on
From the oem server side, try to get to that url.
usually http://xxxx:1810/emd/main I believe.

Automatic discovery of nodes fails

I have two x86 Linux machines both running RedHat 9 with Oracle 9i (9.2.0.4) installed. Both machines have agents running and have been verified using: agentctl status. When I bring up OEM management consoles on each machine they have discovered their own databases but both are unable to automatically discover each others nodes/databases. The nodes can be manually configured and I then have access to both databases.
From within OEM I can ping each agent successfully but only on their respective machines of course, since I have had to manually configure the other node.
I have created net configurations for both using netca and can login to each database using sqlplus with a remote connection from the other machine and database links work also between databases/machines. And tnsping works to each machine at the OS level.
Why can't I automatically discover the nodes if the machines are both running same OS and same database version and the agents seem to be ok? What am I missing?
Any suggestions/help would be appreciated!
Thanks,
-Diane

Facing issue while trying to disable automatic discovery of devices through Apple Bonjour

Hi All,
I am facing issue while trying to disable automatic discovery of devices through Apple Bonjour.
Background: Whenever our application is in running state, devices are automatically discovered if it connects to PC. We are using Apple Bonjour's auto discovery technology( mdnsresponder ).
We are registering a particular service type by using DNS API "DNSServiceRegister". Service type is getting registered properly and we are able to discovered that particular type of device.
Platform: Windows 7.0 / MAC 10.8
Issue:
But we are facing issue while trying to disable auto discovery of a device programmatically. i.e, unregistered a service reference programmatically from our windows application.
To unregistered a service we are using "DNSServiceRefDeallocate" DNS API. But looks like it is not working properly.
Is this DNS API “DNSServiceRefDeallocate” is correct one to unregistered the service?
Here is the step by step procedure that we are following to de-allocate a service reference:
1.Browsing / Query a service by using service type to get service reference (DNSServiceRef).
2.Get reference socket FD by using DNS API "DNSServiceRefSockFD".
3.Select a socket by using "select" API.
4.Close the socket that we got from step 2 by closesocket().
5.Delete the service reference by using DNS API "DNSServiceRefDeallocate" and service reference from step 1.
Are we missing any step to unregistered a service?

Original problem I noticed was that regular websites I go to (such as msn) were only partially downloading. I could see the text on the site but no pictures or videos. All web surfing was extremely slow. When I would go to a site such as man I would see another address in the lower left corner for "ads1.msads.net" or "cdn.optimizely.com" that is was trying to connect to. I tried using all three of my browsers (firefox, safari, chrome) and got the same response on all browsers. After I spent some time researching the issue I decided I probably had a adware/malware problem so I decided to try adwaremedic.com. I could also not access that site along with thesafemac.com or apple.com. I was also getting the same response on my other devices (iPhone, iPad, and a mac air). I could not access any of these sites on any of my devices although I could get to almost any other site although it was very slow. At that point I decided to unplug the router. I also did a number of other things before then to try and manually get rid of any adware. Eventually I got msn back working, apple.com, and the speed was much faster. But, I still can not access adwaremedic and thesafemac.com. I could access these on my phone with 3G but not on my wifi. This is where the problem still stands. I am sure I still have some adware on my computer and need to find a way to remove it. I am no techie so the complicated manual fixes are difficult for me to do.

SCOM Network Discovery - Duplicate nodes with different Device Keys (MAC address)

Hi There,
We have deplyed SCOM 2012 SP1 for server and network monitoring. In the "Network Devices" view, there are few duplicate node entries for the same device. When i look at the details of each entry, the device keys (MAC address) are
different. for example, if there are 3 entires for the same device, only one will have the correct MAC address and remaining 2 are incorrect.
Have anyone came across such issue? Any solution to avoid the duplicates?
Thanks.
Venu.
Best regards, Venu.

Last Thursday (9/25/14), Microsoft provided me with an updated version of a file that is used as part of the discovery process. At first, it appeared to only resolve the issue for some devices which was disappointing. On Saturday, I decided
to remove all managed devices and rediscover everything from scratch. We have 237 devices to monitor. Since Saturday, I had one ICMP only device duplicate itself, but after I removed the duplicate, I have not had any other duplicates created and
there have been many rediscoveries ru nsince then. So far so good. I've asked Microsoft to keep the case open until next Monday. This weekend, I have a full discovery scheduled to run on a schedule. I'll feel good after that if there
are still no duplicates.
The file replaced is "ic-iftable.asl" which is located on each management server in the path ""\[ SCOM install directory]\Server\NetworkMonitoring\rules\discovery". I'm not sure if I'm allowed to share the updated version of
the file. I have not received an explanation from the support technician yet as to the root cause. They took at least 5 sets of trace logs during the discovery and subsequent rediscovery process before giving me this updated file. I'll let
you know.

3 node RAC -1 instnance getting down automatically in one node

Hi,
As you are facing node eviction issue, to find out reason please share following details:
1. clusterware alert log file
2. cssd.log file
3. crsd.log file
4. No. of voting disks (*sometimes if you have only one voting disk, one node will be evicted automatically as i have observed*)

Automatic discovery not working if empty WebSphere Application Server folders in Windows registry

We were trying to discover WebSphere 8.5.5 servers in our environment but the JEE MP couldn't find them. The discovery wrote this kind of error to the Windows Log:
The process started at 8:56:25 AM failed to create System.Discovery.Data. Errors found in output:

I investigated the discovery vbs script and Windows registry and found out that one of the users had empty WebSphere Application Server folder under Software/IBM in Windows registry. This was probably left after uninstallation of WAS. After I removed the
empty registry entry then the auto-discovery found WAS instances.
Would it be possible to enhance the discovery vbs script to exclude empty USER/Software/IBM/WebSphere Application Server key folder in the next version?

I have contacted IIS forum support.
Please review the link: http://forums.iis.net/p/1213109/2079229.aspx?Re+Windows+Server+2012+Printing+using+UNC+path+not+working
Their final response:
Printing from ASP.NET using System.Drawing.Printing itself is a horrible approach, as this namespace was designed for Windows Forms only. The designers did not take everything about ASP.NET in mind, so any issue can happen. That can answer why the HP model
works while the Samsung fails, as the HP one just "happens
to work",
http://msdn.microsoft.com/en-us/library/system.drawing.printing.printdocument.aspx
Similarly, System.Printing was designed just for WPF.
About which printing API to use in ASP.NET/IIS, there is no clear answer so far. Thus, your only resource is Microsoft support, who can perform further analysis (with their dedicate utilities and of course Windows source code) and might come across a solution
to help you out. This is not a trivial scenario.

What is behind the scenes of "Automatic Discovery of Cluster Members?"

Do any of you know the basic mechenism ( or concept ) of authomatic discovery of cluster members?
And how can we be confident that an application deployed anywhere on the network (LAN,WAN, or the Internet) can join a cluster?
Sorry for this clumsy question, but I realy need to know this.
Thanks in advance!
Scott

Hi Scott,
Coherence uses a protocol called TCMP which is described in the following Wiki article:
http://wiki.tangosol.com/display/COH32UG/Network+Protocols
By default, multicast is used to discover if a cluster is already running that the new member may join.
In order to test multicast in your environment, you need to run the multicast test:
http://wiki.tangosol.com/display/COH32UG/Multicast+Test
Some environments don't allow multicast or some switches don't handle multicast very well, in which case you'd need to run using WKA (Well Known Address):
http://wiki.tangosol.com/display/COH32UG/well-known-addresses
Regards,
Jon Hall.
p.s. once you've confirmed that clustering is taking place (either using the default of multicast or using WKA), then you should run the datagram test to test your network's performance:
http://wiki.tangosol.com/display/COH32UG/Datagram+Test
Also, check out the production checklist as this has lots of really good information in it that will be useful going forward:

Automatic discovery of Vista PC on network?

So I have the MacBook, and I have a Windows Vista desktop. They can see each other fine; on my Mac I can click "Go -> Connect to Server..." and put in my Vista PC's IP address and it will come up. Similarly, I can click "Start" and type in my Mac's IP address and it will come up.
My question is why don't they automatically come up in their respective network browsers? Why can't I go to "Go -> Network" and see my PC?
Would appreciate some tips on how to get that going. It's not a huge annoyance that it doesn't work, but it would be nice if it did.
Thanks in advance.

If there was any error message that might help others give you an answer.
I would also go to the PC Firewall and add Port 631 to the File and Printer Sharing option.
I take it that the Firewall is allowing File and Printer Sharing as you said the option was turned On ?
Otherwise I have nothing else.

EM for Coherence - Cannot automatically start departed storage enabled nodes

Hi Guru,
I have a cluster with 4 storage enabled nodes. I want EM to monitor those 4 storage enabled nodes and automatically bring up nodes if down. So i set the "Nodes Replenish and Entity Discovery Alert Metric ->
Cluster Size Change (To Replenish Nodes)" as follows:
 Warning Threshold: Not Defined
 Critical Threshold: 3
 Comparision Operator: <
 Occurrences Before Alert: 1
I manually killed 2 storage nodes and hope EM can automatically bring up them. But unfortunately, this never happen. I even cannot see the correct "Severity Message" displayed on GUI, it always shows "0 nodes departed Coherence cluster".
Did anyone have the similar problem? Any hints are appreciated!
Thanks

Hi,
It looks like your cache servers have not used the correct cache configuration file so they do not have a service with the name DistributedSessions. You can see this in your log output here:
Services
ClusterService{Name=Cluster, State=(SERVICE_STARTED, STATE_JOINED), Id=0, Version=3.7.1, OldestMemberId=5}
InvocationService{Name=Management, State=(SERVICE_STARTED), Id=1, Version=3.1, OldestMemberId=5}
PartitionedCache{Name=DistributedCache, State=(SERVICE_STARTED), LocalStorage=enabled, PartitionCount=257, BackupCount=1, AssignedPartitions=257, BackupPartitions=0}
ReplicatedCache{Name=ReplicatedCache, State=(SERVICE_STARTED), Id=3, Version=3.0, OldestMemberId=2}
Optimistic{Name=OptimisticCache, State=(SERVICE_STARTED), Id=4, Version=3.0, OldestMemberId=2}
InvocationService{Name=InvocationService, State=(SERVICE_STARTED), Id=5, Version=3.1, OldestMemberId=2}
You said in the original post that you used the following JVM arguments:
-Dtangosol.coherence.distributed.localstorage=true -Dtangosol.coherence.session.localstorage=true -Dtangosol.coherence.cluster=CoherenceCluster -Dtangosol.coherence.clusteraddress=231.1.3.4 -Dtangosol.coherence.clusterport=7744
...but none of those specify the cache configuration to use (in your case session-cache-config.xml) so the node will use the default configuration file; the default name is coherence-cache-config.xml which is inside the Coherence jar file.
You need to add the following JVM argument
-Dtangosol.coherence.cacheconfig=session-cache-config.xml -Dtangosol.coherence.distributed.localstorage=true -Dtangosol.coherence.session.localstorage=true -Dtangosol.coherence.cluster=CoherenceCluster -Dtangosol.coherence.clusteraddress=231.1.3.4 -Dtangosol.coherence.clusterport=7744

Problem with childs nodes and automatic key mapping in a Data Object

Hi experts!
I'm doing the service order tutorial from the mobile help at [this link|http://help.sap.com/saphelp_nwmobile71/helpdata/en/21/9b5b924c3b434fba4767731794b029/frameset.htm] and I have a problem...
In the topic "Modeling the Equipment Data Object", says you have to mark the "Automatic Key Mapping" checkbox. So when I had to create a third child node ( the location node ) the system raised an exception with the message "Deselect automatic key mapping flag for more than two-level nodes". I'm trying deselecting the flag and creating the location node, but when I want mark again the automatic key mapping flag, this is disabled.
What can I do to solve this and create the three child nodes with the flag marked? It's a configuration thing?
Any help it's very welcome. Thanks in advance.
Best regards,
Simon.

The thing is: Its not allowed to use automatic keymapping if you have more than two levels. This is why the message showed up, and this is why its been disabled.
What automatic keymapping does: Figures out automatically which child node belongs to which parent (by guessing from the field name and type, which fields in the child correspond to which key fields of the parent).
On three levels, this becomes more complicated => Its disabled.
How to do keymapping yourself instead of having the DOE do it automatically: Do 'Explicit keymapping' from each child to its parent. Explicit keymapping is done by clicking on the corresponding menu button in the child node. Here you need to associate child node fields (they need not be key fields of the child, but they are allowed to be that as well) to each of its parent nodes key fields (so that each child can be associated to its parent).
Cheers

ISE - Discovery Host

Dear All,
I am facing issue with automatic discovery of ISE node by NAC agent (Discovery Host). Our client was using Cisco NAC 3310 appliances which has been replaced by ISE and we have upgraded the NAC agent software as well. Now what is happening that whenever NAC agent starts on a user PC it shows ip address of old NAC manager in the discovery host field of NAC agent and due to this, posture assesment doesn't complete and user gets stuck in remediation state.
As a work arround , I changed the ip address manually in Discovery Host option of NAC agent to point towards new ISE node and then posture assesment gets completed. So kindly advice how I can make this process automatic so that NAC agent should communicated with ISE automatically.
Regards,
Mujeeb

Hi,
It has been resolved without manual entry in NAC agent or NACAgentCFG file. Actually the redirection was not working properly for agent so I changed the redirect ACL as follows,
ip access-list ext ACL-AGENT-REDIRECT
#deny udp any any eq 53
#permit tcp any any eq 80
Kindly refer following document for the same.
http://www.cisco.com/en/US/solutions/collateral/ns340/ns414/ns742/ns744/docs/howto_10_universal_switch_config.pdf
Now the agent is able to find the primary ISE node and posture is woking fine.

Intelligent agent, adding nodes & databases

Hello
I am trying to add remote databases (8i on Linux) using Management Server in OEM (9i on
Windows)
The node successfully gets discovered
But the message in Oracle Home Information that I am getting is
"Oracle Home information not available. Please upgrade to agent version 9.0 or higher."
Linux m/c's node is added successfully. But I am not able to see the nodes like Databases, HTTP Servers, Listeners etc under the node it
And since it has automatically discovered the node, it doesnt give me the option to add the
databases manually
Searched on metalink and got to know (in Note 160427.1) that nmumigr8 utility has to be run
But this needs to be run on the remote database that needs to be added in OEM
I do not have any installation of 9i on Linux
Where will I get this utility ?
Is there anything I am interpreting wrong ?
What shall I do ?

Hi,
Sometimes Agent on target node gets messed up.
Try to clear it up by removing the Linux node from OEM Navigator, then go to Linux box, stop the agent, then remove following files on Linux box:
$ORACLE_HOME/network/agent/*.q
$ORACLE_HOME/network/agent/services.ora
$ORACLE_HOME/network/admin/snmp*.ora
Then start Agent again and check $ORACLE_HOME/network/agent/services.ora - normally you should see database, listener and node as entries there.
If you do not see your database in the file, then probably something messed up with your listener.ora file, cause this is where Agent finds out about your database.
If you do see you database in the $ORACLE_HOME/network/agent/services.ora, then go ahead and do node discovery in the OEM
I have 37 nodes with 60 databases in my OEM setup, it should work. I use OEM 9.2 with targets ranging from 8.1.6 to 9.2
Good luck
Albert

Useful Code of the Day: Hideable Tree Nodes

Someone posted about how they could selectively hide tree nodes, and I already had this AbstractTreeModel class (which does some things DefaultTreeModel does and some it doesn't) and a concrete subclass for TreeNode objects, so I was thinking how one could do hideable nodes. So I came up with this solution.
There's 4 classes here:
- AbstractTreeModel is the base for the concrete TreeNodeTreeModel
- TreeNodeTreeModel extends AbstractTreeModel to support TreeNodes (DefautlMutableTreeNode, etc.)
- HideableMutableTreeNode which is a DefautlMutableTreeNode subclass which has a visible field (with is/set methods, of course).
- HideableTreeModel is the hideable model which is a subclass of TreeNodeTreeModel.
A HideableMutableTreeNode can be set invisible directly, but the tree still needs to be notified to update. So it's best to use the methods in HideableTreeModel which set a node's visibility which notify the tree of changes accordingly. Methods are also provided to check a full path's visibility or ensure a node including all parent nodes are visible.
A HideableTreeModel can take any TreeNode class, it doesn't have to be all HideableMutableTreeNodes, but only HideableMutableTreeNodes can be made invisible, of course. Any other TreeNode type would just be considered visible.
Hiding nodes works basically by making the tree think there's less nodes then there are. And to do this, the node counts and child index search just works by looping thru the parent's children. This has potential perfomance drawbacks of course, since one has to loop thru the node's children to get nodes every time. This could be alleviated by not supporting non-hideable nodes changing the internal maintenance of HideableMutableTreeNode contents. But I'll leave that to whoever really needs it. It shouldn't be a problem if there are are a relatively small set of child nodes in any given parent.
Also, note that the root node in the model cannot be made invisible, cuz it'd be redundant since JTree can be set to hide the root node.

Hey
I'm not trying to show anyone up here, but having just built a tree model for displaying an XML document in a tree, I thought this seemed like a neat exercise.
I implemented this very differently from the @OP. I only have one class, HiddenNodeTreeModel. All the hidden node data is stored in the model itself in my class. The advantage of what I've created is it will work with any TreeModel. The disadvantage is that I think it's not going to be very scalable - the additional computing to get the number of child nodes and to adjust indexes is heavy. So if you need a scalable solution definitely don't use this.
Anyway here you go

Problem in NODE 1 after reboot

Hi,
Oracle Version:11gR2
Operating System:Cent Os
Hi we have some problem in node 1 after sudden reboot of both the nodes when the servers are up the database in node 2 started automatically but in node 1 we started manually.
But inthe CRSCTL command it is showing that node 1 database is down as show below.

JTree Nodes with the same name

What do I have to do to get the JTree to render nodes with the same name? These Nodes user objects are completely different object types and each has a unique hashcode.
+ Root Node
+-- node1 (this is a folder)
+-- node1 (this is a file)
The problem is I have n folders in my tree but if a parent folder contains a folder and a file with the same name then no other subfolders are displayed.
The nodes exist in memory because I enumerate the tree and display its contents in System.out.
Thanks in advance!
Matt

Thank you to everyone that responded. I solved the issue. It was a timing issue...here's my original method:
private void renderProductFolder(SubFolder sf){
try{
WTPart part = QueryHelper.service.findWTPart("number", sf.getNam());
WTTreeNode node = buildWTTreeNode(part);
super.getTreeModel().setRoot(node);
renderTree(node, sf); // This is the problem call
super.getSelectionModel().
setSelectionPath(new TreePath(node.getPath()));
super.expandPath(new TreePath(node.getPath()));
}catch(Exception ex){
ex.printStackTrace();
Here is the fix:
private void renderProductFolder(SubFolder sf){
try{
WTPart part = QueryHelper.service.findWTPart("number", sf.getNam());
WTTreeNode node = buildWTTreeNode(part);
renderTree(node, sf); // This was the problem call

I was originally building the root node, then setting it as the root, then adding additional nodes to the root in the call to renderTree(). So the fix was to build the complete tree structure and then call setRoot(). Otherwise the tree doesn't automatically paint the nodes when they're added via node.add(nodeChild).
It was just a coincidence that I discovered this problem with nodes having the same name.
Thanks for all your great input!
