Permission denied [U02001097] when using attach_res on Java UNIX Agents

Issue/Introduction

When executing jobs on a v24 or v26 UNIX/Linux agent that use the ATTACH_RES command with task-specific resources (AGENT_RESOURCES_TASK), the task fails.

The log shows a permission denied error when attempting to execute the attached binary, 

line x: /agent_path/resources/<CLIENT_ID>/<RUNID>/unzip/unzip: Permission denied

At the same time, the following kind of errors appear in the agent log:

U02001095 Job '<RUNID>' requested task-specific ressource '<CLIENT_ID>:STORE.UNZIP_LINUX/UNZIP'.
U02001097 Job '<RUNID>' use task-specific ressource '<CLIENT_ID>:STORE.UNZIP_LINUX/UNZIP' - '/agent_path/resources/<CLIENT_ID>/<RUNID>/unzip'.
...
U02000009 Job '<JOB_NAME>' with RunID '<RUNID>' ended with return code '126'.
U02000250 Task-specific Storage object '<CLIENT_ID>:STORE.UNZIP_LINUX/UNZIP' - '/agent_path/resources/<CLIENT_ID>/<RUNID>/unzip' removed.
U02000482 Process '<PID>' for Run-Id '<RUNID>', ended with exit code: '126'. Possible error description: 'Permission problem or command is not an executable.'.

The same works fine with Agents Unix C-based (v21 or inferior).

Environment

• Automic Automation Engine 24.x or 26.x
• UNIX/Linux Java Agent v24 and v26

Cause

This is a product defect (DE209345). In v24 and v26 agents, the permissions for task-specific resources are set to rw-r--r-- (644), which lacks the execution bit.

In v21, these were correctly set to rwx------ (700).

Resolution

Workaround

Change the ATTACH_RES syntax to use client-wide resources instead of task-specific ones. This forces the agent to use the &$AGENT_RESOURCES_CLIENT# path, which maintains correct permissions.

1. Locate the ATTACH_RES call in the job script.
2. Update the third parameter to C (Client) instead of T (Task).
3. Update the path to the binary to use &$AGENT_RESOURCES_CLIENT#.

Example modification: 

From:
: ATTACH_RES "STORE.OBJECT", "BINARY", T
 &$AGENT_RESOURCES_TASK#/binary

To: 
: ATTACH_RES "STORE.OBJECT", "BINARY", C
 &$AGENT_RESOURCES_CLIENT#/binary

Solution

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