Issue/Introduction
What does a 3003 abend in and IDMS task or job mean?
Environment
Release: All supported releases.
Resolution
A 3003 abend indicates that the DMCL definition and the physical file do not match as far as Page Size or Page Range is concerned for the area in question.
Whenever IDMS reads a requested page, it checks the page number in the header to be sure it is the page number expected based on the AREA definition included in the DMCL. If that check matches, we then use the Page Size defined in the DMCL to find the Footer of the page and check the page number again. If either the page number check in Header or Footer fails, then a 3003 abend code will be issued.
Execute an IDMSLOOK on the DMCL using the ALL option, and check that it has the correct page size and page range.
There are several possible reasons to receive abend 3003
The DMCL could be correct but the DSname accessed is not the correct file or it has not been correctly FORMATted with the correct DMCL.
The physical area/file is correct, but the DMCL is incorrect as far as page range, page size or DSNAME
