開啟 sqlplus
用 sys 登入 XPEDB1 指定為SYSDBA 的身份

--sqlplus SYS/password@localhost/XEPDB1 as SYSDBA

sqlplus / as SYSDBA

--修改 NLS_CHARACTERSET to ZHT16MSWIN950
shutdown immediate;
STARTUP MOUNT;
ALTER SESSION SET SQL_TRACE=TRUE;
ALTER SYSTEM ENABLE RESTRICTED SESSION;
ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
ALTER SYSTEM SET AQ_TM_PROCESSES=0;
ALTER DATABASE OPEN;
ALTER DATABASE CHARACTER SET INTERNAL_USE ZHT16MSWIN950;
ALTER SESSION SET SQL_TRACE=FALSE;
shutdown immediate;
STARTUP;

查詢 nvarchar 的欄位
select owner, table_name, column_name
from dba_tab_columns
where (data_type = 'NCHAR' or
data_type = 'NVARCHAR2' or
data_type = 'NCLOB') and
owner != 'SYS' and
owner != 'SYSTEM';

要 truncate 兩個 table:
truncate table SYS.RADM_FPTM_LOB$;
truncate table SYS.RADM_FPTM$ ;

執行以下指令

修改 System 的 NLS_NCHAR_CHARACTERSET:
shutdown immediate;
STARTUP MOUNT;
ALTER SYSTEM ENABLE RESTRICTED SESSION;
ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0 SCOPE = MEMORY;
ALTER SYSTEM SET AQ_TM_PROCESSES=0 SCOPE = MEMORY;
ALTER DATABASE OPEN;
ALTER DATABASE NATIONAL CHARACTER SET UTF8;
SHUTDOWN IMMEDIATE;
STARTUP;

要修特定  PDB 的 NLS_NCHAR_CHARACTERSET:
alter session set container=cdb$root;
show pdbs;
alter pluggable database XEPDB1  close immediate;
alter pluggable database XEPDB1 open read write restricted;
alter session set container=XEPDB1;
truncate table SYS.RADM_FPTM_LOB$;
truncate table SYS.RADM_FPTM$;
ALTER DATABASE NATIONAL CHARACTER SET UTF8;
ALTER PLUGGABLE DATABASE XEPDB1 CLOSE IMMEDIATE;
ALTER PLUGGABLE DATABASE XEPDB1 OPEN;
select * from database_properties where PROPERTY_NAME in ('NLS_CHARACTERSET', 'NLS_NCHAR_CHARACTERSET');

1. Go into the Properties window for the project where you want to see stack trace line numbers.
2. Click on the Build "vertical tab".
3. Select "Release" configuration. Check the DEBUG constant parameter.
4. Uncheck the "Optimize code" parameter to avoid the occasional trace issue with inlined code (this step is not essential).
5. Press the Advanced... button and choose Output -> Debug Info -> pdb-only.
6. Deploy the generated .pdb file with the assembly.
