Issue/Introduction

After performing OS patching on an AIX server, the Workload Automation agent is unable to execute any jobs. The jobs fail immediately with the following loader error messages referencing missing runtime definitions for cybspawn.bin

^{exec(): 0509-036 Cannot load program cybspawn.bin because of the following errors:
rtld: 0712-001 Symbol _Is_3stdHQ2_3std11char_traitsXTc_RQ2_3std13basic_ostreamXTcTQ2_3std11char_traitsXTc_PCc_RQ2_3std13basic_ostreamXTcTQ2_3std11char_traitsXTc_ was referenced from module cybspawn.bin(), but a runtime definition of the symbol was not found.
rtld: 0712-002 fatal error: exiting.}

Environment

Product: ESP dSeries Workload Automation / Workload Automation DE

Server Release: 12.4

Agent Release: 12.0 / 12.1

Operating System: IBM AIX 7.3 (Service Pack 7300-02-03-2446 / 7300-04-00-2546)

 

Cause

The issue occurs because the LIBPATH environment variable is either unset, cleared, or failing to properly load the required shared system and runtime C++ libraries for the specific user/owner profile attempting to execute the jobs. This configuration gap is frequently exposed following an operating system update or patching cycle.

Resolution

Configure LIBPATH: Define and append the necessary system paths inside the agent user's login profile (.profile) or within the agent environment configuration file.

Ensure your LIBPATH explicitly includes standard system library locations, such as:

export LIBPATH=/usr/lib:/lib:/opt/freeware/lib:/opt/freeware/lib64:/usr/java7_64/jre/lib/:$LIBPATH

Restart the Workload Automation agent process to clean cache and pick up the updated profile environment configurations. Once restarted, the batch runs will process and complete normally.
