Abstract: When Oracle database software is installed, it will record the host name in the corresponding configuration file during installation.Therefore, in the lab environment, it will need to modify the related configuration information on other servers except for the multicast server after the installation of all machines.So it must increase workload of laboratory staff in a certain extent.In order to improve the Oracle laboratory environment configuration, this paper gives us two kinds of schemes:one is the remedial measures after the installation of the network multicast mode.The other is using virtual machine technology to install Oracle database software.Moreover, during the practical application in the lab environment, these two schemes are implemented and proved that they can improve the efficiency of Oracle laboratory built.
