6. Oracle 全球客户支持（GCS）已经注意到最近的趋势，该趋势是起源于安装了太多的rpm包的而导致的问题，举例：
a.) installing your own JDK version (prior to execute the Oracle Software runInstaller) is not needed on Linux, and is not recommended on Linux. A pre-existing JDK often interferes with the correct JDK that the Linux Oracle Software runInstaller will place and use.
b.) installing more than the required version of the gcc / g++ RPMs often leads to accidentally using (aka enabling or activating) the incorrect one. If you have multiple RDBMS versions installed on the same Linux machine, then you will likely have to manage multiple versions of gcc /g++ . For more information, please see Note 444084.1, "Multiple gcc / g++ Versions in Linux"
