How to reserve Spectrum tcp ports on Linux

Products

• CA Spectrum

Issue/Introduction

Sometimes when starting the Spectrum applications on Linux, they are not able to start because the ports they bind to are already being used by another process.

Environment

Spectrum 10.2.3 and older on Linux

Resolution

To reserve the tcp ports that Spectrum uses, the following can be added to the /etc/sysctl.conf file:

net.ipv4.ip_local_reserved_ports=7777,14002,14003,14004,14006,14012,14013,14014,14016,46517,47870,48879,51966,56063,61904,64222,65259

After adding the above, run the following command:

sysctl -p

NOTE: You must be the root user or have sudo root privileges 

NOTE: The Spectrum 10.3 installation updates the /etc/sysctl.conf file with the Spectrum ports.

Additional Information

For a complete list of ports used by Spectrum processes, please reference the "Default Port Configurations" section of the documentation.
