1.Problem phenomenon

At a customer’s site, colleagues use Ogg 19 version to register DB 19 in the extraction process integration mode and report an error

OGG-08221,OCI Error ORA-44004 invalid qualified SQL Name

CAUSE
The issue is due to the value of "TEST.1DC.COM" for source_global_name

  value="TEST.1DC.COM"     <=============== 
A database global name has other restrictions than normal sql objects.Several creative database names cause the register
 of Integrated Extract to fail as these names fail in dbms_assert.qualified_sql_name().
Example names are:
  ABC.COMPUTE-A1111.ORACLECLOUD.INTERNAL  # the Minus sign in the domain part
  TEST.1DC.COM                               # a part of the domain name starts with a number
  
SOLUTION
Please do the following to change from TEST.1DC.COM to TEST.DC.COM and then redo the REGISTER
SQL> alter database rename global_name to TEST.DC.COM
Note: Above change may break database links that point to this instance if using global naming.
On multi-tenant environments OGG currently checks following to sql names. 
1: global name of the container db 
2: full global name of the pdb 
3: short dbname of the pdb. 
So in addition to above change following is also needed on PDB
ALTER PLUGGABLE DATABASE RENAME GLOBAL_NAME TO <newname>

Does the actual customer use this special name?Domain is not set for parameter query

select value$ from sys.props$ where name=’GLOBAL_ DB_ NAME’;

This confirms the global of the registered PDB_ DB_ There is a special character in name. Ogg internal integration registration obtains this name through DB parameters. Subsequent operations cannot resolve this special character and an error is reported!

The solution is to adjust the parameter name of PDB and delete special characters!
