Issue/Introduction

After upgrading to  Db2V12 FL100, the field PACKAGE-PROGRAM-LONG in ARCIACDP is being truncated to 18 characters.

Example: 

DATE            PROGRAM

2019-09-07  REQ03023_CHECK_FOR_EXSTNG_REC

2019-09-09  REQ03023_CHECK_FOR           

Environment

Release : 20.0

Component : CA Insight Database Performance Monitor for DB for z/OS

Resolution

After analyzing user  SMF data and it was discovered that all long fields offsets from the IFCID 239 are wrong.
IDB2 code identifies the bad offsets for long fields name and just copy the short name to the long one.
This is an IBM bug introduced recently in this year for DB2 12.
Here is the link the IBM fix:
