Oracle XE installation and oraclexe Installation
I. unmount the original databaseThe database uninstallation is not much said. Let's talk about the process: 1. Execute Oracle Uninstall, uninstall Oracle product 2, delete all Oracle related items under regedit 3, restart the machine 4, SC delete Oracle Related Services 5, manually delete the <Oracle_Home> directory, and C: \ Oracle directory under Program Files 6. Delete manually added environment variables Note: You must delete the environment variables you have added. I did not delete ORACLE_HOME at the beginning, causing an error, it took N minutes to complete the problem.Ii. Install XEThe Installation Process of XE is very simple. It is completely the installation method of the application software. You can keep clicking "Next", but I have encountered several problems during installation: the execution address of the process created by the producer is inexplicable and cannot be started at all. This is also true for manual creation, which is quite depressing. All in all, the XE installation is very opaque, resulting in a lot of problems, you can only delete and reinstall. However, it can be inferred that almost all installation problems are caused by the fact that the previous Oracle version has not been deleted, there will be very few errors on machines that have never installed Oracle. After deleting N times, I cleared all the previous installation parameters. The installation was successful. The following is the installation information: Target Folder: D: \ oraclexe \
Port 1521 of The 'oracle Database Listener'
'Oracle service for Microsoft Transaction Server' port: 2030
Port Number of the HTTP listener: 8080 or lower is the default service: OracleJobSchedulerXE OracleMTSRecoveryService OracleServiceXE OracleXEClrAgent OracleXETNSListener3. Delete XE 

There is no delete option in the startup Item after installation. One way to delete XE is to delete all installation information, just like deleting a common Oracle. The other is to directly open the installation file and select "delete ", you can achieve one-click deletion. After deletion, restart the machine. Otherwise, some information is retained.
