About the versions

Where for major versions you need a new license and for the minor versions the same existing license is maintained on OpMon.

Prerequisites

Before starting the update for the major version it is necessary to update to the latest version minor, and for that you need the following:

  • OpMon needs to have access to the following address: http://repo.opservices.com.br
  • Always check the erratas related to the version of the update that you will conduct. Click here to check the versions changelogs;
  • Backup the opcfg: For safety it is recommended to backup the opcfg. In order to do this run the following command:
[root@opmon]# /usr/local/opmon/utils/opmon-base.pl -e opcfg
  • Move the backup: using the following command, and then move the backup to a folder other than the daily backup:
[root@opmon]# mv /var/tmp/opmondb/opcfg/ /var/tmp/

Version update (minor)
