Ebusiness suite export import create PDB admin user

HI ,

In 2554156.1 export import ebusiness suite 19C

point 5 : Create the target database instance

Use SQL*Plus to connect to the CDB as SYSDBA and run the following commands to create the PDB.

$ sqlplus "/ as sysdba"

SQL> create pluggable database "<PDB SID>" admin user <PDB admin user> identified by <password> file_name_convert=('<CDB file location>/<CDB SID>/pdbseed','<PDB file location>');

==> What user should I choose for PDB admin user is it SYS or APPS or free user...

thanks
