Step 1: The scott user in the EXP original US7ASCII database. Step 2: EXP original US7ASCII database zhaoboyi users in the database. Step 3: CREATE New Database (Character Set Simplified Chinese_China.zHS16GBK), all paths are the same as the original database.
Step 4: Put the init in the zhs16GBK. Ora Copy Init. ORA. Bak. Step 5: Put the init in US7ASCII. ORA COPY ZHS16GBK Modify the corresponding parameters. Step 6: Generate Scott users in the zhs16GBK, authorized, and scott users in Exp Zs16GBK. Step 7: Generate zhaoboyi users in ZHS16GBK, the zhaoboyi users in Exp ZHS16GBK. Step 8: Open (US7ASCII) and (ZHS16GBK) Scott users with UltraEdit, and change the US7ASCII in the top 5 lines. Step Ninth: Corresponding to the Zhaoboyi user. Step 10: In ZHS16GBK, execute the Owaload of the SYS user. SQL, for HTP. P Authorization. Step 11: Do IMP, pour the original database into the new database. Step 12: Solve large fields. First, the stored procedure fwrite_clob_niu is executed in the original database, and the table containing the large field is generated into the file, then compiled fupdate_clob_text in the new database, reverse the big field to the new database. Appendix 1.
