CRCVALUE 代码

CRCVALUE 代码

Informatica 对 XML 文件中您可以修改的元素有限制。导出 Designer 对象时，PowerCenter 客户端可能在 XML 文件的一个或多个元素内包含循环冗余校验值 (CRCVALUE) 代码。CRCVALUE 代码是元素中的另外一个属性。
如果 PowerCenter 客户端在导出的 XML 文件中包括 CRCVALUE 代码，则可以先修改部分属性和元素，然后再将对象导入到存储库中。例如，VSAM 源对象始终包含 CRCVALUE 代码，因此只能修改 VSAM 源对象中的部分属性。如果修改包含 CRCVALUE 代码的元素中的特定属性，则无法导入对象。
例如，如果修改源对象中的 OWNERNAME 属性，则无法将源导入到 Designer 中。
以下 XML 显示含有 CRCVALUE 代码的源对象元素的一部分： 
<SOURCE NAME ="SALES_FILE" DBDNAME ="SALES.CBL" IBMCOMP ="YES"
CRCVALUE ="3108520154" OWNERNAME ="" DESCRIPTION ="" BUSINESSNAME ="" DATABASETYPE ="VSAM" ...>
</SOURCE>
元素 SOURCE 的 CRCVALUE 属性为 3108520154。
导出 Designer 对象时，PowerCenter 客户端在 XML 文件中包括 CRCVALUE 代码。
