ITM 6.2.x Linux and Unix O/S Agents in a 6.3 environment may result in zero-value weighted averages

Content

A enhancement was made to the 6.3.0 version of the Linux and Unix O/S agents to increase the accuracy of the aggregated data. The Linux and UNIX OS agents added WHSC columns in the ODI files (docklz and dockux) to handle receiving invalid row data. Customers that migrate their ITM environment to 6.3 that still have 6.2.x agents will experience a condition where certain attributes will appear as 0. The affected tables and related attributes are listed below:

Linux_OS agent:

Table Linux Network / KLZNET

APAR IV43893 has been created to address this issue. A fix will be provided for 6.3 FP01, and this will be included as part of 6.3 FP02. You must install this patch before you add 6.3 O/S agent Application Support or upgrade to the 6.3 version of the Linux or Unix O/S agents.

The fixes for APAR IV43893 are attached to this document. Please see the README file for installation instructions.
