Explanation

https://docs.oracle.com/database/121/NLSPG/ch2charset.htm#NLSPG1035 Creating a Backup of the root.sh Script Oracle recommends that you back up the root.sh script after you complete an installation. If you install other products in the same Oracle home directory, then Oracle Universal Installer updates the contents of the existing root.sh script during the installation. If you require information contained in the original root.sh script, then you can recover it from the backed up root.sh file. Choosing a Database Character Set for a Multitenant Container Database In Oracle Database 12c, all containers of a multitenant container database (CDB) must have the same database character set and the same national character set. That is, all pluggable databases (PDBs) in a CDB must have the same character set as the CDB's root container. The character sets of the root container are considered the character sets of the whole CDB. You can consolidate multiple databases by plugging them into a single CDB. These databases can be traditional, non-CDBs or PDBs unplugged from other CDBs. Three situations may happen depending on the database character set of a database being plugged in, that is, a new PDB: - The character set is the same as the database character set of the CDB. In this case, the plugging operation succeeds (as far as the database character set is concerned). - The character set is plug-in compatible with the database character set of the CDB. Plug-in compatible means that it is a binary subset of the CDB's character set and both are single-byte or both are multibyte. In this case, the database character set of the new PDB is automatically changed to the database character set of the CDB at the first open and the plugging operation - The character set is not plug-in compatible with the database character set of the CDB. In this case, the new PDB can only be opened in restricted mode for administrative tasks and cannot be used for production. Unless you have a tool that can migrate the database character set of the new PDB to the character set of the CDB, the new PDB is unusable.
