mainframe - GDG 滚入错误

Question

在执行一个 Proc 时，我收到“GDG Roll In Error”。错误消息显示 'IGD07001I GDG ROLL IN ERROR -RETURN CODE 20 REASON CODE 0 MODULE IGG0CLEG'。 proc 应该创建 19 代的 GDG。创建前 6 个 Generaton 后会发生此错误。 GDG 的参数是 Limit=100, NOEMPTY,SCRATCH。可能是什么原因？
专家，请帮助。

Answer 1

如果你查找IGD07001I它说，除其他外，要看IDC3009I返回和原因代码的解释。对于返回代码 20 原因代码 0，IDC3009I 表示

RETURN CODE 20 Explanation: There is insufficient space in thecatalog to perform the requested update or addition.

The catalog cannot be extended for one of the following reasons:

• There is no more space on the volume on which the catalog resides
• The maximum number of extents has been reached
• The catalog has reached the 4GB limit
• There is not enough contiguous space on the volume (required when the catalog's secondary allocation is defined in tracks).

Programmer Response: Scratch unneeded data sets from the volume.Delete all unnecessary entries from the catalog. The catalog may needto be reallocated and rebuilt if these steps do not resolve the spaceshortage.

我建议联系您的 DFSMS 管理员。我还建议为 z/OS documentation 添加书签为您的版本/发布。
