Environment

Product: CA Automic Workload Automation - Linux Agent v24.x

Cause

The temporary directories are mounted with noexec flags, preventing execution of files within them. This can be verified witht he command below.

mount | grep /home/<USERNAME>

 

If the result of the command above has noexec as shown below, then the user cannot execute any files within the temporary directories.

(rw,nosuid,nodev,noexec,relatime)

 

Resolution

Please ask the System Administrator to remove the noexec from the directory or directories in the path shown in the error.  For example:

Exception in thread "main" java. lang. UnsatisfiedLinkError: /home/<USERNAME>/. cache/JNA/temp/jna17888832707216736686. tmp: /home/oracle/.cache/JNA/temp/jna17888832

may require noexec to be removed from /home

and in:

Exception in thread "main" java.lang.UnsatisfiedLinkError: /tmp/jna4021440535280609014.tmp: /tmp/jna40214405352806

noexec may need to be removed from /tmp

A system admin will know more about where it should be removed.
