ILM partition change done in UTC time instead of Client 0 Timezone

Products

• CA Automic Workload Automation - Automation Engine

Issue/Introduction

Since the AE was upgraded from 12.3.x to 21.x ILM partition change is not being executed at the correct time (00:00) as per the Timezone defined in Client 0 (TZ.CET.0).
In the Central European Timezone, ILM takes place at midnight UTC time which corresponds to 01:00 or 02:00 depending on DST.

Please note that the issue occurs ONLY if the Timezone has 8 characters (TZ.CET.0).

Examples in the logs:

20240103/010026.655 - U00003479 Logging was changed.
20240103/011014.945 - U00005367 Checking consistency of table IPH.

Expected behavior: ILM partition change should execute at 00h of the TZ defined on client 0.
Actual behavior: ILM partition is being executed at 00h UTC time instead of the 00h of the TZ defined on client 0

Environment

Affects Automation Engine 21.0.x with ILM enabled.

Cause

Defect, the issue could occur if the name of the Timezone attached to client 0 had 8 characters.

Resolution

Workaround:

Reduce the lenght of the Timezone Object to 7 or less characters (ie. TZ.CET instead of TZ.CET.0)

Solution:

Update to a fix version listed below or a newer version if available.

Fix version:
Component(s): Automation Engine
Will be fixed in Automation.Engine 21.0.10 - Planned release end April 2024
Automation.Engine 24.0.0 - Available
