Host target availability

Can someone tell me how can I send notification only for host target and not for agent?
I mean that when a ping (icmp) to the host is unavailable, a notification would be sent.
Thanks,
Or.

Yes although both Agent and Host rule the same Management Agent ping, they use two notification rules. i.e Oracle OEM checks hosts and agent at the same time and sends you two messages one for host notification and the second for agent notification.
If a customer wants to be notified when the host is physically down, Oracle will still run and generate two alerts but all you do is disable it from sending the agent notification out on the host you want to in one of two ways.
Go to Notification Rules for “Agent Unreachable” as per above, click on Edit and select Apply rule to specified agent targets, and select all targets except the target owned by customers that do not want to be notified.
Or
Go to Setup, Agents, click on the host you want to disable agent notification, click on Metric and Policy Settings, and it will show agent metric for that host, you will see a metric called status (and collection schedule called based on management Agent), you can have this disabled. I have done this but it is not recommended, and you can only disable it for the host via sql. I have a script for this if you want.

12c change host target name / ip address without reinstalling agent

Is there a way, to change the configuration?
Details: Host target was added manually, agent was deployed successfully, the host name is an IP address, dns is not working here.
Now the IP address was changed, I can not add a new host using the new address, because em says the agent base directory is not empty...
I just want to add a new host without removing the previous agent installation.
Or even simpler, change the configuration of the existing host (that is name displayed in EM and host IP address).
I am somewhat confused, it seems to be not possible, or I cannot see it after searching quite some time through the different menus and the documentation.
Any hint, please?

We have tested steps to re-point an existing agent to a new OMS without requiring re-push of the agent binaries. The same steps should work for what you are trying at achieve, although note you will have to remove the original targets, so target history will be lost. The only piece this avoids is re-push of the agent binaries. The steps are:
1. Shut down the running 12c agent with the below command:
$AGENT_INSTANCE_HOME/bin/emctl stop agent
2. Remove the agent instance home:
rm -rf $AGENT_INSTANCE_HOME
3. Manually remove the targets monitored by the agent in the EM console.
4. Create a new instance home pointing to the new oms:
$AGENT_BASE_DIR/core/12.1.0.1.0/sysman/install/agentDeploy.sh
AGENT_BASE_DIR=<location of the agent base dir> OMS_HOST=<oms hostname>
EM_UPLOAD_PORT=<http/https upload port>
@ AGENT_REGISTRATION_PASSWORD=<registration password>
AGENT_INSTANCE_HOME=<absolute path where the instance home has to be created>
-configOnly
We will get these steps added to the official documentation. Let us know if you run into difficulties.
Thanks, Mark.

Add host target after deleting it in OEM 12c

I am running OEM 12.1.0.3. I have deleted a host target on the console and now I want to add it back. If I go to "Add Target" -> "Add Target Manually" -> "Add Host Target", it will prompt for installation of agent on that host. I do not want to go through that process since agent is already installed and running on the host. I also tried "auto discovery result" but the host isn't listed there even though the agent is a managed target in OEM. Is there a easy way to add the host back? Thanks.

Hi Team,
You can follow the below steps to re-add the host target
1. Start the agent by issuing following command:
<AGENT_INSTANCE_HOME>/bin/emctl start agent
2. Issue following command:
<AGENT_INSTANCE_HOME>/bin/emctl config agent addinternaltargets
3. Secure the agent by issuing following command:
<AGENT_INSTANCE_HOME>/bin/emctl secure agent
4. Do the following steps to show the status of host and agent as up:
<AGENT_INSTANCE_HOME>/bin/emctl stop agent
<AGENT_INSTANCE_HOME>/bin/emctl clearstate agent
<AGENT_INSTANCE_HOME>/bin/emctl start agent
Once done, the host and agent status would be shown as up.
5. Do a resync of agent as per below steps
1. Login to 12C console
2. Navigate to Setup --> Manage Cloud Control --> Agents (for 12.1.0.2 OEM)
Navigate to Setup --> Agents (for 12.1.0.1 OEM)
3. Click on the problematic agent
4. Click on drop down menu "Agent" and Choose "Resynchronization" in the menu list.
5. Choose the option to "Unblock agent on successful completion of agent resynchronization." and Click on Continue
6. The resynchronization operation is submitted as a job
7. Check the job's status of the resynchronization operation by clicking on the job name's link.

Host Target not discovered

Hi,
We have reinstalled the OEM agent in an existing host. However, when we monitor from GC UI console we do not find the host name under the list of targets in target hosts page.
We can see that the agent has been discovered in the target agents home page. The agent has discovered the targets in the target host box. We can find the list of hosts in the targets.xml file. However, none of the targets discovered by the agent is visible in the targets page in GC UI console, also emctl agent config listtargets , also shows the list of targets discovered by the agent on the target host.
Not sure why the targets that are being discovered by agent are not being displayed in GC UI console.
Regards,
Rup

By default, the Add Host Targets Wizard configures only the following types of plug-ins:
◦All discovery plug-ins that were configured with the OMS from where the Management Agent software is being deployed.
◦Oracle Home discovery plug-in
Oracle Home monitoring plug-in
By default, the host and the Management Agent get automatically added to the Enterprise Manager Cloud Control console for monitoring. None of the targets running on that host get automatically discovered and monitored.
To monitor the other targets, you need to add them to Enterprise Manager Cloud Control either using the Auto Discovery Results page, the Add Targets Manually page, or the discovery wizards offered for the targets you want to monitor.
For information about discovering targets in Enterprise Manager Cloud Control, refer to the chapter on adding targets in the Administrator's Guide: http://docs.oracle.com/cd/E24628_01/doc.121/e24473/toc.htm

Host-target application for setting the PC(host) time to cRIO(target)

if there is any host-target application for setting the PC(host) time to cRIO(target)? if probably a sample program provided?

Hi Charles,
There's a function called RT Set Date and Time that you can make use of.
We don't have a sample program but this is a very simple VI to use. Read off the current date time in Windows, then enter the corresponding info into this VI and run it. The cRIO controller will then have its date time updated accordingly.

Boon Chen

Machine/Host information available to ABAP

Would anyone know how could I find out the specs of the host where an (the current) ABAP program is running?
I know there is the SY-HOST field available to identify the host name, but I couldnt find any other system fields.
I am interested in the following:
1) OS on machine
2) OS version
3) Memory on machine
But most importantly ...
4) The types of CPU (Brand, Model & speed)
Any help would be great! Thanks.

Hello Sumit,
If you look at it one way, the solution to your query is quite simple. All the details that you are asking can be found via the menu path System-->Status. Now this menu is there virtually on every screen in SAP. So one would like to think that there ought to be a Function Module for that!! Now if you debug for a few seconds, you will find that the FM is <b>STATUS_ANZEIGEN</b>.
Of course this FM will have a screen which would be used to display the information. What you need to look at is the code of the FM other than the call to the screen. Just try this piece out.
DATA: BEGIN OF VERSION_INFO OCCURS 0,
        LINE(80),
      END OF VERSION_INFO.
CALL 'SAPCORE' ID 'ID' FIELD 'VERSION'
               ID 'TABLE' FIELD VERSION_INFO-*SYS*.
loop at version_info.
write : / version_info.
endloop.
Now just don't ask me to explain you the call to the C-Function. It's a secret !!:-)
Have fun. And get back if you have trouble.
Regards,
Anand Mandalika.

Encounter another error when adding host target in EM 12c

Hi, all
After installing EM 12c successfully, I then tried to add target to the EM, I encountered such error:
Error Message: The Oracle Management Server (OMS) host and port specified via OMS_HOST and EM_UPLOAD_PORT is not available. Pass in a valid hostname and port number for the OMS to successfully deploy the agent.
Exit Code :1
Again I am sure that my host name is reachable and port number it complains is open.
I also opened the SR with oracle support, the SR is 3-6060170341.
I would appreciate if anyone can help and shed some light on this issue.
Regards.
Yong

As i mentioned earlier if you need help from Oracle pls open a Service request (SR) with oracle support and upload the following logs:
<OMS_INSTANCE_HOME>/sysman/agentpush/*.*
Share the SR number.
Can you also ping the oms host from agent host and vice-versa?
Do you have any firwall ?
While deploying the agent using Add host wizard, keep the port input field blank and it will pick up the next free port automatically. There is some env setup issue which is causing this in both install types.
Once you log an SR, Oracle support will help you, they will look into your env and find the root cause. Posting small snapshot of failure in forum can’t be debugged further without logs or a web conference.

Re:ORA-12545 error (host target)

Can anyone shed some light on this... I have just installed red hat linux 9 and have been trying install Oracle 9.2 (i have followed many instructions from sites and have done all the export cmds etc...). But i keep getting a ORA-12545 error when trying to connect (no target host found)i have looked at the listener.ora file and cant seem to see anything wrong. What else can i do to solve my problem??? Ian.

There are several issues that you have to check out.
ORA-12545: TNS:name lookup failure
Cause: The listener on the remote node cannot be contacted.
Action: Perform these steps:
Verify that the ADDRESS in the tnsnames.ora file and the listener.ora file is correct.
Verify that the listener on the remote node has been started. Enter:
lsnrctl
LSNRCTL> STATUS [listener_name]
listener_name is the name of the listener defined in the listener.ora file. It is not necessary to identify the listener if you are using the default listener, named LISTENER.
If the output indicates the listener is not running, try starting it with the command:
LSNRCTL> START [listener_name]
First than nothing :
1.- Can you get connection locally in the Server ?

Agent ok but host not available

Hello All,
I've reconfigured my agent by following article 413228.1, i.e. clearstate agent, and cleaning up the files before restarting. My agent is now up and running but i do not see the host on which the agent is running. I've tried everything and can only think of uninstalling and reinstalling the agent.
I can see my databases on that host but i can't not see the host as a target. Has anyone experienced this? In other words, i can't to a refresh host..I can run upload agent fine from the server.
Thanks.

Yes host was viewable to OMS..weird thing is that it was known to OMS as a different name. For instance, the hostname is hostA but in OMS, it used to be known as hostB. There was a hosts file entry with hostB= IP address of host A. This was put in place so that the application can work.
Since then, we've cleaned up the hosts file but the hostB entry remains! Where does OMS get the machine name of the server from? I've looked everywhere in the config files and all have the entry hostA not hostB.

Cannnot remove host target in Grid Control 10.2

Chaps,
I'm trying to remove a agent discovered in grid. I've done:
1) agent is running
2) removed all database targets, listeners etc discovered in grid
3) shutdown agent
4) tried removing the host from either the hosts or all targets page, but the remove just hangs for ages and then comes up with:
"No Response from Application Web Server"
Grid is running ok as far as I can tell.
Anyone with any advice before I raise yet another SR?
Thanks,
Bazza

Sorry too lazy to search!! Apologies.
In the end I did (on oracle support advice):
exec mgmt_admin.delete_target ('<name o/t target>','<type o/t target>',0,0,1);
exec mgmt_admin.cleanup_agent('<name o/t agent>');
And that appears to have done the trick. Was that your script?
Neither script took long to run.
Thanks,
Bazza

Dma transfer between host & target

Attachments:
Test VI ( Host).vi ‏171 KB
Test VI (FPGA) .vi ‏33 KB

Oh I was typing my query in a notepad & forgot to paste it. Sorry!
So here i am trying to pass two data streams from host to target FPGA through FIFOs. I want to process these data streams on FPGA & write the output in another FIFO & give it back to the host. I have made a simple model for it. Forgive my ignorance but i dont understand the behaviour of the program when i set Count ( Loop Timer) to a low value like 20 ticks. What is actually happening when i want the FPGA VI loop to run faster? What I can i do to make sure that no output data is lost?
Secondly are there any other constraints while using multiple FIFOs?
I am using PXI-7842R & LabVIEW 8.6.1

Problem discovering host targets - Routing error

Hi,
I am trying to discover targets using the auto discovery, and I get an error related to the nmap command.
I tried with a privileged user as well as the root user, but both ways it fails with the error below:

Ok. Just confirming this is a vanilla linux install and hardware.
Network discover (Nmap) must be run as root user. And in EM that means you must configure privilege delegation and sudo/pbrun on the host running nmap. You mentioned you tried privilege delegation before so I assume you have this configured correctly and tested.
If you still have issue, then please open an SR as we will need the logs and more details of the host to troubleshoot.

Metric: SAP Host Agent Availability doubt

Hello folks!
I have a problem in technical monitoring from Solution Manager, and i would be happy, if someone could help me with this.
1 - SAP Solution Manager is trying to ping a IP that doesnt exists
2 - In the screenshot, the line is: "Ping to listener: xxx.xxx.xxx.xxx:port not successful".
Let's call the host of my managed object as "$HOST_NAME", and the IP as "$HOST_IP".
1 - The IP of $HOST_NAME is one, and the IP xxx.xxx.xxx.xxx that SolMan is trying to ping, is another, the ip doesnt even exists, because i can't reach him from anywhere. Is it not wrong? I think the "Listener" should be the $HOST_IP, not another...
2 - The correction for this problem, would be the adjustment of the "Listener" to the $HOST_IP? How could i do this?
Thanks already

Hi,
Host agent runs on physical machine.
Can you goto agent admin and find host name and IP from there.
