Is there any function to get the hostname of a OSB server at runtime?

I need to fetch the OSB server hostname and use it as a qualifier to fecth the value from DVM, as we fetch the BPEL instance URL using ora:getProcessURL() .

example :

If i am able to get the server url as : http://dev-osb-clientname.com

I will extract the "dev" from there and i will send "dev" to DVM as a qualifier.

You can make an Assign using this XQuery:

let $hostVar := fn-bea:execute-sql(
"jdbc/MetroIntegrationDS", 
"host", 
"select decode (sys_context('USERENV','SERVER_HOST'),'DB-SERVER-PROD' ,'PROD', 
  'DB-SERVER-DEV', 'DEV' ) myhost from dual")
return $hostVar//*:MYHOST/text()

in you targer Variable you'll get "PROD" or "DEV" according to the Machine name of OSB's DB.

We also faced this issue and sorted using java code and using java callout for the same.

You can consider below dummy fragment and take idea:

    package OsbServerName;

import java.io.Serializable;
import java.security.PrivilegedAction;
import java.util.Iterator;
import java.util.Set;

import javax.naming.Context;
import javax.security.auth.Subject;

import weblogic.jndi.Environment;
import weblogic.management.MBeanHome;
import weblogic.management.runtime.ServerRuntimeMBean;

/*
* Get OSB Server or Host Name

 */
public final class OsbServerName implements Serializable {

                private static final long serialVersionUID = 4055048819845029320L;

                private final static String serverName = findServerNameURL();


                public static final void main(String[] arg) {

                }

                /**
                * Return the server name
                * 
                 * @return
                */
                public static final String getServerNameURL() {
                                return serverName;
                }

                /**
                * find OSB/WLS server name
                *

                */
                private final static String findServerNameURL() {
                                try {
                                                return findServerRuntimeMBean().getDefaultURL();
                                } catch (Exception e) {

                                return "";
                }
