Issue/Introduction

Attempting to run an ADS application, the following abend is occurring:

 

IDMS DC081001 V1 T51018 TASK: ADS2; MAP TIME-DATE STAMPS IN MAP MAPNAME AND APPL PROGRAM: ADSOMAIN(DLGNAME) DO NOT AGREE

 

What does this mean and how can it be resolved?

Cause

When a MAP is compiled (generated) with a critical change, the date and time of the compilation is stored in the map load module.
This can be viewed with the following display:

 DCMT D MEM PRO APPLDICT.MAPNAME 32
Program: IJHMPAGE  Dictname: APPLDICT
 <Addr>   <Offset>                 <Hex>                    <Character>
3F4F7A00  00000000  C9D1C8D4 D7C1C7C5 F1F161F1 F861F1F9  *MAPNAME 11/18/19*
3F4F7A10  00000010  F0F6F3F4 F2F2D9F2 00000000 00000000  *063422R2........*

When the related dialog is compiled, that time-stamp is copied into the dialog load module:

 DCMT D MEM PRO APPLDICT.DLGNAME 64
Program: IJHDPAGE  Dictname: APPLDICT
 <Addr>   <Offset>                 <Hex>                    <Character>
3F4F6200  00000000  C6C4C25C C9D1C8C4 D7C1C7C5 F1F161F1  *FDB*DLGNAME 11/1*
3F4F6210  00000010  F861F1F9 F0F6F3F5 F2F6F4F8 C9D1C8D4  *8/1906352648MAPN*
3F4F6220  00000020  D7C1C7C5 F1F161F1 F861F1F9 F0F6F3F4  *AME 11/18/190634*
3F4F6230  00000030  F2F2D9F2 C5D4D7E2 C3C8D440 C5D4D7E2  *22R2EMPSCHM EMPS*

Note that the time-stamp at offset x'24' of the dialog load module is the same as the time-stamp at offset x'8' of the map load module.
At run-time, these two time-stamps are checked and if they are not the same, the task is abended with the DC081001 message.
This is a mechanism built-in to ensure that the map and dialog are in synchronization with each other.

A critical change to a map is one that requires dialog compilation, such as the addition or deletion of fields, and is identified by message DC366115 when the map is compiled.
A non-criticial change is less severe, such as a cosmetic change or positional move of an existing field. This results in message DC366119 when the map is compiled.

Environment

Release : All releases
Component : CA IDMS

Resolution

Dialogs are automatically varied NEW COPY when compiled in ADSC.
Maps are not, so it may be necessary to issue DCMT V PR APPLDICT.MAPNAME NCI in order to avoid this abend.

Also the map time-stamp check can be disabled by the use of optional bit 252, although this is not recommended.
