Hello everybody,
since a couple of weeks we are facing an issue on two HP UX systems that are connected to our Solution Managers MAI. Every couple of days we receive the alert "SAP Host Agent not running". Having a look into the according metrics, we find the information:
SAP OsCol Web Service Availability
[RC=600] URL http://system1:1128/SAPOscol/?wsdl called unsuccessfully [Reason: Error to perform http request cause by java.net.SocketException: Socket output stream shutdown by peer..; nested exception is: java.net.SocketException: Socket output stream shutdown by peer.]
SAP Host Agent Web Service Availability
[RC=600] URL http://system1:1128/SAPHostControl/?wsdl called unsuccessfully [Reason: Error to perform http request cause by java.net.SocketException: Socket output stream shutdown by peer..; nested exception is: java.net.SocketException: Socket output stream shutdown by peer.]
To fix this problem we are logging into the system and restart the SAP Host Agent, which gives us a couple of days until the alert returns.
Today I was trying to have a closer look and found out:
1. Doing "telnet system1 1128" right on the command line of the system that is showing this problem leads to telnet connecting and immediately showing "Connection closed by foreign host." Doing the same but restarting the Host Agent before leads to a connection that will remain connected. Therefore I do not think the problem has anything to do with the SolMan connection.
2. Checking the sapstartsrv.log gives me some messages:
3. Using the guide "How to analyse the missing performace data situation and how to check SAPOsCol issues - Netweaver Technology - SCN Wiki" and the syntax "saphostctrl -function GetSAPOSColVersion" shows
Doing this after the Host Agent has been restarted:
4. I also found this entry in the host_profile file, which is discussed in the article above:
But I am not sure if there has to be a certain order for the service/porttypes.
Any idea what might be going wrong here and how to fix this issue?
Thanks in advance!
Daniel
