Oracle Faq (Oracle's character set issue) _php basics

1, in the construction of the library, Catproc must run, otherwise use Rman will appear the following character set error:
Rman-00554:initialization of internal Recovery manager package failed
Rman-04005:error from Target database:ora-06553:pls-213:package STANDARD Noe
Rman-04015:error setting target database character set to zhs16cgb231280
If there is no problem when building a library, then you can re-run catproc.sql. This would in turn call the Dbmsbkrs.sql script which creates the Dbms_backup_restore package.

2. Chinese Character Set description
zhs16cgb231280 cgb2312-80 16-bit Simplified Chinese MB, ASCII
ZHS16GBK GBK 16-bit Simplified Chinese MB, ASCII, UDC
Simply put, ZHS16GBK is a superset of zhs16cgb231280.
1990 China, Japan, Korea jointly developed the unified East Asian ideographic character set, commonly known as the GB extension code character set (GBK).

3. How to avoid Chinese support problems
Our usual advice is to plan when you are building a library so that there will be no problems.
1) Create Database
Character Set ZHS16GBK
National Character Set ZHS16GBK
2 environment variable: Nls_lang=american_america. Zhs16gbk
Best Export nl2004-10-20_format= ' yyyy-mm-dd HH24:MI:SS ' specified date format;
3 If the props$ is specified in the library characterset must be ZHSS16GBK:
Nls_characterset ZHS16GBK
Nls_nchar_characterset ZHS16GBK
If you are not able to use update changes, but this will have an impact on existing data, or even cause the entire database is not available, so after the library is built to verify, a good DBA is able to avoid problems as far as possible, rather than wait until the problem to fire.

This way there will be no more questions about character set and Chinese support. Do you have any more questions? and I Contact:)
