Character set Utilities

Database Character set utilities

The Database character set scanner access the feasibility of migrating an oracle database to new database character set. This database characterset scanner checks all character data in the database & tests for the effects & problem of changing the character set encoding.

The method of migrate the database's character sets.

1. Export & Import utilities.
2. CSALTER Script
3. CSALTER with Export & Import utilities on selected tables.

Scan modes in the Database character set scanner.

1. Full database scan

2. User Scan

3. Table Scan

4. Column Scan

How to Install Chractet set scanner:

1. Create a user named CSMIG

2. Assign the necessary privileges to CSMIG

3. Assign the Default ts to CSMIG

3. Create the character set scanner system tables under CSMIG

Use csminst.sql script to modify default tblespace for CSMIG.

% cd $ORACLE_HOME/rdbms/admin
% sqlplus sys/password as sysdba
SQL> @csminst.sql
