Notes:

Hostname must be consistent.

Otherwise, there are various errors:

For example:

[oracle@C1 j2ee]$ emctl start dbconsoleThe following exception occurred: java.net.UnknownHostException: C1.zongxuan.onlien: C1.zongxuan.onlien at java.net.InetAddress.getLocalHost(InetAddress.java:1346) at oracle.sysman.emd.targetIntg.agent.AgentTargetInstaller.getLocalHost(AgentTargetInstaller.java:4282) at oracle.sysman.emd.targetIntg.agent.AgentTargetInstaller.printLocalHost(AgentTargetInstaller.java:4252) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at oracle.sysman.emd.targetIntg.Util$DefaultIntegrationMethod.execute(Util.java:598) at oracle.sysman.emd.targetIntg.TargetInstaller.execute_(TargetInstaller.java:167) at oracle.sysman.emd.targetIntg.TargetInstaller.execute(TargetInstaller.java:155) at oracle.sysman.emSDK.conf.TargetInstaller.printLocalHost(TargetInstaller.java:2364) at oracle.sysman.emSDK.conf.TargetInstaller.main(TargetInstaller.java:3290)Although there was an exception it might be possible for the program to continue.OC4J Configuration issue. /usr/oracle/app/product/11.2.0/dbhome_1/oc4j/j2ee/OC4J_DBConsole_null_zx not found.

This is the problem with hostname settings.

The problem below is that environment variables are not set properly

export ORACLE_UNQNAME=sid(sid of oracle)[oracle@C1 ~]$ emctl start dbconsoleThe following exception occurred: java.net.UnknownHostException: C1.zongxuan.onlien: C1.zongxuan.onlien at java.net.InetAddress.getLocalHost(InetAddress.java:1346) at oracle.sysman.emd.targetIntg.agent.AgentTargetInstaller.getLocalHost(AgentTargetInstaller.java:4282) at oracle.sysman.emd.targetIntg.agent.AgentTargetInstaller.printLocalHost(AgentTargetInstaller.java:4252) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at oracle.sysman.emd.targetIntg.Util$DefaultIntegrationMethod.execute(Util.java:598) at oracle.sysman.emd.targetIntg.TargetInstaller.execute_(TargetInstaller.java:167) at oracle.sysman.emd.targetIntg.TargetInstaller.execute(TargetInstaller.java:155) at oracle.sysman.emSDK.conf.TargetInstaller.printLocalHost(TargetInstaller.java:2364) at oracle.sysman.emSDK.conf.TargetInstaller.main(TargetInstaller.java:3290)Although there was an exception it might be possible for the program to continue.Environment variable ORACLE_UNQNAME not defined.
