linux 安装oracle

注意事项：

hostname 一定要保持一致

不然还有各种报错：

例如：

[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.

这个就是hostname 设置的问题

下面的这个问题是没有设定好 环境变量

export ORACLE_UNQNAME=sid(oracle的sid)

[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.
