Update PDB GLOBAL_NAME to Uppercase

To support Oracle Thesaurus Management 5.4, update the PDB GLOBAL_NAME in Oracle Database 19c to uppercase.

1. Log in to Oracle Database 19c.
2. Enter:
   alter session set container="<PDB NAME>"
   For example: alter session set container="lsw3qa5"
3. Enter the customer-created pluggable database (PDB) name and domain in uppercase letters:
   update GLOBAL_NAME set GLOBAL_NAME='<PDBNAME.DOMAIN>'
   For example: update GLOBAL_NAME set GLOBAL_NAME='LSW3QA5.US.ABC.COM'

   Caution:

   Do not use spaces or special characters (for example, *, &, @, %) in the global name or you cannot connect to or recover the database.
