SiteMinder : Error: "JRE libraries are missing or not compatible..." when installing policy sever / AdminUI

Products

• SITEMINDER

Issue/Introduction

During the installation of the policy server, the installer halts with the error, 

"JRE libraries are missing or not compatible....
Exiting...."

Environment

SiteMinder Policy Server 12.8.x or later

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.
