Software requirements

The software requirements for Arenadata DB installation are listed below:

  1. ADB supports the following operating systems:

    • RHEL 7.9.

    • CentOS 7.9.

    • AltLinux 8.4 SP (for the Enterprise edition of ADB).

  2. ADB requires the XFS file system. Other file systems (including EXT4) are not supported.

  3. It is recommended to switch off any antivirus software before ADB installation.

  4. During ADB installation, the following changes are made at the operating system level. Do not change any of the objects listed below.

    • The following system files are modified:

      • /etc/fstab

      • /etc/hosts

      • /etc/hostname

      • /etc/chrony.conf

      • /etc/ssh/sshd_config

      • /etc/selinux/config

    • Some new files are created in the following folders:

      • /usr/lib/systemd/system/

      • /etc/cgconfig.d/

  6. For online installation of ADB, all cluster hosts should have access to Arenadata repositories specified on the Configuration tab in the ADB cluster menu available via ADCM UI (see Arenadata repo url and Monitoring repo url fields).
