Deploy Oracle 10g Grid Control Agent

Deploy Oracle 10g Grid Control Agent today again tried to deploy the Grid Control Agent. previously, it went quite smoothly. Today, the following error message suddenly appeared: Completed with Status = 255 Starting Oracle Universal Installer... checking installer requirements... checking operating system version: must be enterprise-4, enterprise-5, redhat-3, redhat-4, redhat-5, redhat-5.1, SuSE-9, SuSE-10, UnitedLinux-1.0 or asianux-1 Passed All installer requirements met. P Reparing to launch Oracle Universal Installer from/tmp/OraInstall2013-03-21_08-07-42PM. please wait... completed with Status = 255 I suddenly thought that I did not delete the relevant information when I deleted the Agent during my experiment. So I tried the following: $ cd/u01/app $ cd ContentsXML/$ vi inventory. xml <? Xml version = "1.0" standalone = "yes"?> <! -- Copyright (c) 2009 Oracle Corporation.
