Getting host name in clustered environment

Hi,
in my J2EE Web application, I'd like to get the hostname of the Portal server where my J2EE app is deployed. But this is a clustered pipeline system where many servers exist in our QA system.
So if I were to try:
java.net.InetAddress addr = java.net.InetAddress.getLocalHost();
String hostname = addr.getCanonicalHostName();
I am not sure what the call to getCanonicalHostName would return to me?
Does it always give me the domain name of the central instance? e.g. s1.abc.mycompany.com
Or can it give me the domain name of any of the instances?
Has anyone tried this before?
Alternatively within my program is there anyway to determine which pipeline system I am on - dev, QA or production?
Appreciate your response.
Sharath

Hello Sharath.. I guess below statement can be useful to create clusterInformation object
IClusterInformation clusterInformation = (IClusterInformation) PortalRuntime.getRuntimeResources().getService("com.sap.portal.runtime.system.clusterinformation.clusterinformation");
The above object can be useful to get hostname/ip and cluster elements info....

Network Error []: Cannot Get Host Name when running business rules

Guru's
We are getting the following error intermittently when we are running business rules (Planning Application >>Tools>>Business Rules) or running SmartView refreshes:
Network error []: Cannot Get Host Name
The following is then logged in the Essbase Application logs:
Local/Application/Database/admin@Native Directory/Error(1042022)
Network error []: Cannot Get Host Name.
A quick look at the Essbase Error Messages Doc says it is a network error and we have to consult the network documentation. Unfortunately this is not very descriptive so we logged an SR with Oracle but we don't seem to be getting a resolution.
The environment is 11.1.2.0 and the architecture is as follows:
Server 1 - MS Server 2008 x64:
Planning, Calc Manager, Foundation Services, Framework Web Services, EAS, APS, Web Analysis, FR Web Services
Server 2 - MS Server 2008 x64:
Essbase Server
Server 3 - MS Server 2008 x64:
Framework Services, FR Print Services
We have tried doing the following:
1. Put in the server host names into the hosts file on the Hyperion Servers
2. Applied the following TCP/IP settings on all the Hyperion Servers and one of the user machines as a test:
      - Added a new DWORD Value named TcpTimedWaitDelay and set it to 30.
     - Added a new DWORD Value named MaxUserPort and set it to 65534.
     - Added a new DWORD Value named MaxFreeTcbs and set it to 6250
3. Confirmed that there are no packet drops by monitoring the server NICs so no packet loss could be the cause of this issue
4. The Essbase Config file has the following settings:
NETDELAY 2000
NETRETRYCOUNT 2500
Has anyone come across this issue and if you managed to resolve it, how did you go about it.
Thanx

Hi Rahul
The issue is happening to a number of calcs so it it not one calc specifically. I will ask the functional consultants to enhance the logging in the business rules so that we can see if the issue happens on a specific member\block etc and yes we do use Xrefs
We can run this as a calc in EAS without any issues and it's intermittent because this business rule runs 95% of the time in Planning Application >> Tools >>Business Rules without any issues.
Thanks

Stored procedure for getting host name, host instance and status of that host is it running or stopped.

Hello all,
yesterday I got one task in that I have to stored procedure for getting host name, host instance and status of that host is it running or stopped.
any body knows where exactly, In which table this details are there in BizTalk databases.
thanks

Status of the host instance is not stored in the SQL database for you to query the status using stored procedure. You have to either use Powershell or WMI to get the status.
In SQL, following table contains the details about the host like Name, LoginName, IsDisables etc but status of the host instance is not stored in the database.
SELECT * FROM BizTalkMgmtDb..adm_HostInstance
Powershell to get the status:
http://axonolympus.nl/?page_id=186&post_id=969&cat_id=6&lang=en
WMI to get the status:

Getting host name or ipaddress for viirtual server

I want to get the ipaddress or host name for virtual server in a cluster environment. If i do
java.net.InetAddress.getLocalHost().getHostName()
it returns the ipaddress of the physical node currently running virtual server.
Is there any way to get the ipaddress or host name for virtual server ?

Might help to define what you actually mean by "virtual server" and what you actually want as well (and from what process.)
For example a clustered system with a single entry point. And you want the client to have the entry point. In this case the virtual address (ip and/or host) should always be returned. You can't get the individual address of a specific server. If that is not the case then something is wrong with the clustered system, not java/client.
Another example, a server in the cluster. Then it only knows about its own real address. If you want the cluster then you have to explicitly deliver that information to it, the box itself does not know it.
Something else?

How to get host name in the workflow?

Hi,
I've a requirement where I need to get CQ Inbox url (http://<hostname>:<port>/inbox) in my custom workflow process. I thought of configuring url to some node and retriving from there.. but It's not the good approach as host name will be different for differnt CQ environments. So what is the best way of getting inbox url?
Env: CQ 5.6
Thanks
Siva

Yep Justin, If the configuration is wrong, any link generated would also be wrong.. I mean, default configuration will be some thing like..
I mean, I can change those configurations as per my instance host name, right?
Example: my instance's host url is: mytest:1501
So I would like to update the same in configurations ..

This is the host and port of the URL that this application is launched from.

A couple of suggestions:

Getting host name

I am using serverSocket and the .accept() method to wait for a connection and I want to store the address of the computer that connects to the server. Is there a way to do this?

Yes. accept returns a Socket and you can get the remote InetAddress from that and from that in turn get the host name.

Getting Host Name From Forms 6i (deployed in 10g AS)

My appserver (Oracle 10g AS)resides in HOSTB
And user launches the application from HOSTC
My requirement is to get the host name of the user while he launches the application. ie HOSTC in this case.
If I am trying with java.net.InetAddress.getLocalHost().getHostName(); I am getting the value HOSTA(Host name of Data base server)
If I am trying with SYS_CONTEXT I am getting HOSTB(Host name of appserver)
And my requirement is to get HOSTC !!!
I have read that if Webutil_clientinfo.get_host_name is used I can get the host name of client machine. But since I am working with forms 6i , I can't use Webutil.
please help me if you know any way to achieve the same in forms 6i

Getting host name from applet

Hi All,
How can i get the local host name from applet ( Host name where the applet running) . While i tried with InetAddress i got only the loop back address 127.0.0.1. Can anyone help me out in this regard.
Thanks in advance
V.S.Saravanan

When you say you tried the InetAddress, did you try the following?
You could try creating a Socket connection back to the host/server URL from where the Applet was downloaded (you should have permission to do this). You can then get the local address of the Socket.
Something like:
String hostName = getCodeBase();
Socket s = new Socket( hostName, portNum );
InetAddress address = s.getLocalAddress();
String hostName = address.getHostName();

// Setting Host IP Address...
try
     remoteAddress = InetAddress.getByName(request.getRemoteAddr());
     //This will give you the full qualified domain name of the client
request.setAttribute("reportHostName", remoteAddress.getCanonicalHostName());
catch(Exception e)
     logger.error(e.getMessage(), e);

Is it not IPv6 by any chance?It is. And if I remember correctly, then "0:0:0:0:0:0:0:1" (or "::1" for short) is the IPv6-equivalent to "127.0.0.1", i.e. it's the loopback device.
