AXA host config considerations

• CA App Experience Analytics

Issue/Introduction

These are some notes to bear in mind when deploying AXA 17.3 relating to host resolution

Environment

Release : 17.3

Component : APP EXPERIENCE ANALYTICS ENGINE

Resolution

• Check /etc/hosts and /etc/hostname on each machine and compare IP address resolution to ifcfonfig and ip addr on each one. Check if there are differences in upper or lower case, the installer process checks are case sensitive.
• Check if dnslookup is enabled - if not, the installer will complain about hostnames. This does not break the install
• Do not use spaces, underscores or other such characters in hostnames
• Check the hostnames to be used with command 'hostname' and make sure they are present in /etc/hosts -files for each node. 
• Fully qualified domain name (FQDN) is needed by the installer as the first hostname after IP Address in /etc/hosts
• The hostname used is the first resolved hostname in /etc/hosts. Example: FQDN FIRST otherwise the jarvis installer fails with many "no such file" - note that install script uses 'nslookup' to verify hostname or IP Address
