Oracle Character Set Conversion (6): 5.3. US7ASCII environment CSSCAN execution result
Examine the US7ASCII environment CSSCAN execution result. Schema creation, directory creation, csscan execution result file scan.txt, scan.out, scan.err content, execution result table backup contents can be checked.
This is a continuation of the previous article.
Oracle Character Set Conversion (5): 5. Oracle Recommended Practice
5.3. US7ASCII environment CSSCAN execution result
5.3.1. create schema
Execute the script below on the US7ASCII instance to create a schema for csscan execution.
-- US7ASCII sqlplus sys/________@oraus7 as sysdba @%ORACLE_HOME%\rdbms\admin\csminst.sql sqlplus sys/________@oraus7 as sysdba ALTER USER CSMIG DEFAULT TABLESPACE USERS; EXIT
- Line 3: Execute csminst.sql to create objects such as csmig user (schema) and tables required for csscan execution. At this time, the default tablespace for the csmig user is set to system.
- Line 5: Change the default tablespace of csmig user to users. You can change to another tablespace other than users with sufficient storage space.
5.3.2. create directory
Create a directory to save the csscan execution result and move to the directory.
mkdir D:\Temp\csscan\US7ASCII cd D:\Temp\csscan\US7ASCII
5.3.3. run csscan
Execute csscan with the following command at the Windows command prompt.
csscan \"sys/________@oraus7 as sysdba\" full=y tochar=AL32UTF8
Two parameters are specified.
- full: Specifies Y to scan the entire database.
- For reference, you can specify the scan target user as a user parameter or specify the scan target in detail with table and column parameters.
- tochar: Specify AL32UTF8, the target character set to be converted (CHAR, VARCHAR2, CLOB, LONG type scan)
- For reference, to scan NCHAR, NVARCHAR2, and NCLOB types, you need to specify the tonchar parameter.
5.3.4. Check csscan execution result-scan.txt (result summary report)
The entire content of scan.txt in the US7ASCII test environment is as follows.

Among them, the content of “Application Data Conversion Summary” is not Oracle System Data, but the data created by the user, scanned by type.
[Application Data Conversion Summary] Datatype Changeless Convertible Truncation Lossy --------------------- ---------------- ---------------- ---------------- ---------------- VARCHAR2 2,580,031 0 4,507 14,855 CHAR 0 0 0 0 LONG 0 0 0 0 CLOB 29,628 8,291 0 1 VARRAY 0 0 0 0 --------------------- ---------------- ---------------- ---------------- ---------------- Total 2,609,659 8,291 4,507 14,856 Total in percentage 99.121% 0.315% 0.171% 0.564%
The interpretation of the above is as follows.
- When changing to AL32UTF8 for VARCHAR2 type, 2,580,031 values can be converted without change (Changeless), 4,507 values are truncated (Truncation), and 14,855 values are lost/broken (Lossy).
- When changing the CLOB type to AL32UTF8, 29,628 values can be converted without change (Changeless), 8,291 values can be converted (Convertible), and 1 value is lost/broken (Lossy)
- There is no conversion target for other CHAR, LONG, VARRAY type data.
Changeless, Convertible, Truncation, and Lossy in the above content were written in the previous article, and will be noted once again below.
Oracle Character Set Conversion (5) – 5.2. How to use CSSCAN
| Status | Description |
| changeless | Data remains the same in the new character set – No data change during character set conversion |
| Convertible | Data can be successfully converted to the new character set – Data can be changed during character set conversion |
| Truncation | Data will be truncated if conversion takes place – Data is truncated when converting character set |
| Lossy | Character data will be lost if conversion takes place – Data loss (broken) when converting character set |
“Distribution of Convertible, Truncated and Lossy Data by Table” and “Distribution of Convertible, Truncated and Lossy Data by Column” are scan results for each table and column.
Below are some excerpts from the file.
[Distribution of Convertible, Truncated and Lossy Data by Table] ...

LEG.SUB_MON_STAT 0 4,507 14,854 LEG.Z_TEST 0 0 2 -------------------------------------------------- ---------------- ---------------- ---------------- [Distribution of Convertible, Truncated and Lossy Data by Column] ...

The interpretation of the above is as follows.
- When the LEG.SUB_MON_STAT table is changed to AL32UTF8, no value is normally converted, 4,507 values are truncated, and 14,854 values are lost/broken. As follows for each column
- COMMT: When changing to AL32UTF8, no value is normally converted, one value is truncated (truncation), and one value is lost/broken (Lossy)
- LINE_NUM: When changing to AL32UTF8, no values are normally converted, 3,238 values are truncated (truncation), and 7,426 values are lost/broken (Lossy).
- REF_DES: When changing to AL32UTF8, no value is normally converted, and one value is lost/broken (Lossy)
- SUB_STA_NM: When changing to AL32UTF8, no values are normally converted, 1,268 values are truncated, and 7,426 values are lost/broken.
- When the LEG.Z_TEST table is changed to AL32UTF8, no value is normally converted, no value is truncated, and two values are lost/broken. The VAL column corresponds to this.
5.3.5. Check csscan execution result-scan.out (scan target table information)
In the scan.out file, you can check the list of scan target tables.

In the scan.err file, you can check the details of character set conversion errors for each table and column.

5.3.7. CSSCAN execution result table backup
CREATE TABLE Z_CSSCAN_COL_SUMMARY

So far, we have looked at the results of CSSCAN execution in the US7ASCII environment. Next, we will look at the results of running CSSCAN in the KO16MSWIN949 test environment.
