Meet the following prerequisites before you upgrade the Data Collector:
  • Before you upgrade, verify the zip and unzip packages are installed. If these packages are not installed, use the following command to install them:
    yum -y install zip unzip
  • The Data Collector uses the "at" package to schedule the restart of the application when assigning a Tenant or IP Domain. Verify whether the "at" package is installed on each Data Collector host:
    rpm -qa | grep ^at
    If the command does not return a result, install the package:
    If you are not the root user, use the sudo prefix.
    yum install at
