Hello Praveen,

Please make sure the Host Agent is actually running on the System in question. You can check that with "/usr/sap/hostctrl/exe/saphostexec -status"

The next thing to check would be the Host Agent Ports 1128 (http) / 1129 (https) which are used for the communication between SAPMC and Host Agent.

You may check these with "netstat -a" (or something similar). At least port 1128 should be open and should have the status "listening". The SAPMC settings must also be set to use http / https.

Also, please make sure there is no firewall preventing the communication.

To get a clear picture of the situation, you should provide the Host Agent Version (saphostexec -version) and the Host Agent logs which can be found in /usr/sap/hostctrl/work.

The most important logfiles are dev_saphostexec and sapstartsrv.log

You may have a look there. Normally, the logs are quite readable and maybe there is a hint to where the problem is.

Hello Praveen,

You need to update your SAPMC. In the past, the Host Agent offered the GetComputerSystem Webmethod without any user authentication but due to security reasons this was changed.

You still have an older version of the SAPMC. With the latest Version, the connection to the Host Agent should work again.

Please have a look at note 1014480 on how to update the SAPMC.

Hi ,

But in same SAPMC we are getting data for other systems.

Hello Praveen,

On the systems which provide the data are older Host Agents installed which work with your version of the SAPMC.

To be on the safe side you should upgrade the SAPMC and upgrade your Host Agents. But the new SAPMC will also work with older Host Agents.

See Note 1031096 for information about Host Agent upgrade.

Hello Praveen,

at this point it would be the best to open a CSS Message on component BC-CCM-MC and provide access to the systems (SAPMC system and Host Agent system).

This way I (or my colleagues) can have a look directly and figure out what the problem is.

Hi Praveen,

Let's recapitulate the situation: You restarted the Host Agent and the System. The Host Agent is running now. If you enter "saphostexec -status" you see something like this:

saphostexec running (pid = 19852)

sapstartsrv running (pid = 19855)

08:33:11 27.01.2014     LOG: Using PerfDir (DIR_PERF) = /usr/sap/tmp

saposcol running (pid = 19884)

Please let me know if all of this is correct.

Now my questions:

1.) Is is possible to do a ping from your system where the SAPMC runs to the system where the Host Agent runs ?

2.) On the Host Agent System, please execute this command: netstat -a -p | grep 1128

It will show you if the Host Agent is listening on this port. Please post the output here.

3.) Please have a look at the Host Agent logfile /usr/sap/hostctrl/work/sapstartsrv.log to determine if the Host Agent encountered problems when starting. Are there any error messages ?

4.) Do you have any Firewall settings blocking port 1128/1129 in your landscape ?

5.) Please execute the following command: "/usr/sap/hostctrl/exe/saphostctrl -function GetComputerSystem" and let me know if you see data about your system.

Best Regards,

Christian

True but we had already tried with the root with ./saphostexec -start,restart.

We are able to see the process but its not fetching data in JAVA MC.

Hi,

What is the result if you run ps -ef |grep host ?

Also is sapstartsrv running and has it been running since sap is started on this java host? i.e. if sapstartsrv process is older than running java sap processes I would recommend full restart of java and also ensuring cleanipc is done and sapstartsrv is stopped and newly started.

As the hostagent interfaces via the sapstartsrv process I have seen in past this causes problem.

Please advise.

Hi Praveen,

You need to run the above query with root user.

Hi,

Your server team should configure your sudoers file to allow the sidadm user to run commands against the saphost agent.

Otherwise only works with root user.

possible commands:

sudo /usr/sap/hostctrl/exe/saphostexec -restart  

sudo /usr/sap/hostctrl/exe/saphostexec -stop

Hi ,

I think problem is related with /etc/services file ,I am not able to find entries related with hostagent.

Please suggest.

Regards

Praveen

[christian_schwarzenberger]

Hello Praveen,

your /etc/services should include the following entries:

saphostctrl	1128/tcp   # SAPHostControl over SOAP/HTTP
saphostctrl	1128/udp   # SAPHostControl over SOAP/HTTP
saphostctrls	1129/tcp   # SAPHostControl over SOAP/HTTPS
saphostctrls	1129/udp   # SAPHostControl over SOAP/HTTPS
