Issue/Introduction

When executing a UNIXFS command within a PREP_PROCESS function in Automic Automation v24 or v26, the system fails to find relevant files even though they are there

• The GET_PROCESS_INFO function with the ROWS option returns 0 (or 0000000000000000).
• The script used may look something like:
  
  :SET &HND# = PREP_PROCESS("AGENT_NAME", "UNIXFS", "*.txt", "PATH=/opt/Automic/Agents/AGENT_NAME/temp", "FSPAR=mtime=",20260526 1344" size=10000,", "UC_LOGIN=LOGIN.NAME")
  :PROCESS &HND#
  :   SET &LINE# = GET_PROCESS_LINE(&HND#)
  :   PRINT "Valid file ready for processing: &LINE#"
  :ENDPROCESS
  
  
• In version 21.0 and previous, the following might show in the report:

Environment

Agent: UNIX
Version: 24, 26

Cause

This behavior is caused by a confirmed software bug in the ucxelx6f component of the UNIX agent. This issue is tracked under defect ID DE190846.

Resolution

A permanent fix for this defect will be included in a future release. Currently, there is no estimated time of arrival (ETA) for this fix.

Workaround

As a temporary measure, replace the problematic component with the version from a v21.0 agent:

1. Obtain the ucxelx6f binary from an Automic Automation version 21.0 agent installation.
2. Navigate to the bin directory of the affected v24 agent.
3. Replace the existing ucxelx6f file with the v21.0 version.
4. Ensure the file permissions and ownership match the original agent configuration.
