While trying to create user in Oracle Database 18c Express Edition I kept getting an “ORA-65096: invalid common user or role name” error, which didn’t make sense to me so after validating my command, that I was signed in as an admin user, and determining that my “CREATE USER” was formatted correctly. I did some additional research and determined that in the hidden parameter “_ORACLE_SCRIPT” needed to be set to “True” starting with the Oracle Version 12c and higher.
the “_ORACLE_SCRIPT” values
To set the “_ORACLE_SCRIPT” hidden variable to “True” you need to run an “Alter” command. Then you will be able to create the desired user and run your grants commands as usual.

which can be very useful in Linux, Unix, and AIX. The primary purpose of the move command is

Oracle provides a few ways to determine which database you are working in. Admittedly, I usually know which database I’m working in, but recently I did an Oracle Database Express Edition (XE) install which did not goes has expected and I had reason to confirm which database I was actually in when the SQL*Plus session opened.
