Error description
Client reported the following messages since migrating to z/OS 1.7: - IEW4007I FIND FOR MODULE xxxxxxxx FAILED BECAUSE DIRECTORY ENTRY IS NOT VALID FOR A LOAD MODULE. CSV003I REQUESTED MODULE xxxxxxxx NOT FOUND. CSV028I ABEND806 RC04 - The client's modules in question have aliases and were last linkedited with the S/360 Linkage Editor. ISPF 3.4 browse of these modules show ???????? for alias of. The module aliases load fine prior to z/OS 1.7. This is due to a code change introduced in base z/OS 1.7. The x'88' at byte x'20' into the directory entry is causing the code added at z/OS 1.7 to consider the alias directory entry as invalid. The high order bit being on ( x'80' ) indicates PDSAOSLE (Module has been processed by AOS Linkage Editor). As a result, code that enforces some of the newer rules indicates that the old directory entry is not valid. In particular, an old directory entry that indicates it is of an "alias" could be rejected. -
Local fix
Re-link / re-bind the affected modules. Another option is to IEBCOPY the dataset to a PDSE and then copy it back to a PDS ( or vice versa ). This causes the BINDER to get invoked under the covers and all modules to be re-linked. - Following zap will only work for IEWLCNVX at ++APAR level AA16259 or with OA16259 / UA27612 applied. An IPL will be be necessary if neither are on. - ++ZAP(IEWLDR00). NAME IEWLDR00 IEWLCNVX VER 0003AC 4780,C3BC REP 0003AC 47F0,C3BC VER 0003EC 4780,C3FC REP 0003EC 47F0,C3FC VER 000454 4780,C464 REP 000454 47F0,C464 VER 00049C 4780,C4AC REP 00049C 47F0,C4AC VER 000584 4780,C594 REP 000584 47F0,C594 VER 0005C8 4780,C5D8 REP 0005C8 47F0,C5D8 * end of zap - The above zap removes new directory entry checking added at z/OS 1.7 that is leading to the IEW4007I messages.
Problem summary
**************************************************************** * USERS AFFECTED: Those with very old load modules * **************************************************************** * PROBLEM DESCRIPTION: IEW4007I FIND FOR MODULE xxxxxxxx * * FAILED BECAUSE DIRECTORY ENTRY IS NOT * * VALID FOR A LOAD MODULE. * **************************************************************** * RECOMMENDATION: * **************************************************************** After migration to z/OS 1.7, receive the following messages for old load modules (which previously could be loaded): - IEW4007I FIND FOR MODULE xxxxxxxx FAILED BECAUSE DIRECTORY ENTRY IS NOT VALID FOR A LOAD MODULE. CSV003I REQUESTED MODULE xxxxxxxx NOT FOUND. - In addition, an ISPF 3.4 browse of these modules will show ???????? in the Alias-of field. - Changes in z/OS 1.7 to enforce directory entry rules do not take into account differences in the directory entries created by the S/360 linkage editor. This APAR addresses additional cases beyond OA16259 and supersedes that fix.
Problem conclusion
Loader is updated to accept directory entries as valid when PDSAOLSE is off in the directory entry, indicating that the directory entry was created prior to the existance of the AOS linkage editor or the Binder. KEYWORDS: R10COEXS/K ZOS0201C/K ZOS0202C/K ZOS0203C/K
