Issue/Introduction

During the installation of CA Business Intelligence JasperReports Server 7.1.1 on a Linux system, the Installation Prerequisites system check fails on Free Memory:

Although the system meets the prerequisites and has 8 GB of RAM, with 6 GB of Free Memory, as recommended in the documentation: 



Cause

The CABI installer uses Linux OS tools to determine the available free memory.  If the installer returns FAIL for Free Memory and there are enough GB of RAM allocated, it is likely due to OS Kernel Caching.  

Environment

Release : 7.1.1

Component : Spectrum Integrations

Component : Performance Management Integrations

Resolution

To resolve the problem, open another shell session while the installer is still running and clear the caches with the following command:
free && sync && echo 3 > /proc/sys/vm/drop_caches && free


Other recommendations:

1. Stop all applications and programs on the system and retry. 

2. Try to prevent applications and programs that are started at system boot from starting and then reboot the system.

3. Run the above mentioned command to free up memory: 

free && sync && echo 3 > /proc/sys/vm/drop_caches && free

Additional Information

CA Business Intelligence JasperReports Server 7.1.1 documentation shows these prerequisites for GUI installation

Total Memory - This is the RAM size of the system. - Minimum 8 GB
Free Memory - This is the FreeMemory on the RAM - Minimum 6 GB
