This article explains how to change IP Addresses for cluster nodes of the Aternity Vertica Database Server.

Vertica is a third-party column-store database optimized for large volume data analytics. The Aternity Vertica Database Server stores the performance data in the Vertica format, which is most efficient for displaying in Aternity dashboards. It receives its data from the Aternity Docker Components Server.

Procedure

  1. Step 1 Create the file that maps IP addresses of database nodes.

    For example, 10.0.0.10 10.0.54.215
  2. Step 2 Stop database using administrative tools. Learn more.
  3. Step 3 As dbadmin user, run $ admintools -t re_ip -f mapfile
    Run the command from the node where the IP mapping file was created.
  4. Step 4 When prompted, enter yes. See the status of performed tasks.
  5. Step 5 Start database using administrative tools.
