一、問題現象
同事在某客戶現場，使用OGG 19版本，對DB 19進行抽取進程集成模式注冊，報錯
OGG-08221,OCI Error ORA-44004 invalid qualified SQL Name
二、匹配MOS
OGG-08221 Cannot Register Or Unregister EXTRACT <extractname> Error: OCI Error ORA (Status = 44004-ORA-44004: Invalid Qualified SQL Name)
(Doc ID 2514820.1) Oracle GoldenGate Command Interpreter for Oracle Version 12.3.0.1.181120 OGGCORE_12.3.0.1.0OGGBP_PLATFORMS_181207.1227_FBO AIX 6, ppc, 64bit (optimized), Oracle 12c on Dec 10 2018 09:15:59 GGSCI > register extract <extract_name> database 2019-03-04 16:07:30 ERROR OGG-08221 Cannot register or unregister EXTRACT <extract_name> because of the following SQL error:

CAUSE The issue is due to the value of "TEST.1DC.COM" for source_global_name BINDS #4866688648: Bind#0 oacdty=96 mxl=08(08) mxlc=00 mal=00 scl=00 pre=00 oacflg=01 fl2=1000000 frm=01 csi=873 siz=96 off=0 kxsbbbfp=12211adb0 bln=08 avl=08 flg=05 value="<extract name>" Bind#1 oacdty=96 mxl=15(15) mxlc=00 mal=00 scl=00 pre=00 oacflg=01 fl2=1000000 frm=01 csi=873 siz=0 off=8 kxsbbbfp=12211adb8 bln=15 avl=15 flg=01 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>
那么實際客戶使用了這種特殊的名稱嗎？ 參數查詢沒有設置domain
select value$ from sys.props$ where name='GLOBAL_DB_NAME';
這才確認注冊的PDB的GLOBAL_DB_NAME 存在特殊字符，OGG內部集成注冊通過DB參數獲取這個名稱，后續操作無法解析這個特殊字符報錯！
那么解決辦法，就是調整PDB的這個參數名稱，刪除特殊字符！
