Environment

 

CA Access Gateway (SPS) 12.8SP4 on RedHat 7;

 

Cause

 

The /tmp directory is mounted with the option "noexec", which doesn't allow the execution of binaries.

The mount command reports:

  # mount
  tmpfs on /tmp type tmpfs (rw,nosuid,nodev,noexec,relatime)

Resolution

 

• Ensure you have the root permissions, and remount the /tmp directory with exec permissions:
  

  # mount -o remount,exec /tmp

  
  or without direct root access:
  

  # sudo mount -o remount,exec /tmp

  
  Once the installation and configuration are done, set the noexec permissions back by running this command as root:
  

  # mount -o remount /tmp

  
  or without direct root access:
  

  # sudo mount -o remount /tmp

• Without having root permissions, get in touch with the system administrator to mount the /tmp folder with the execution (exec) permission.
