Add components

In ADCM a component means a part of a service that should be deployed on one or several cluster hosts. For example, ADB service consists of such components as ADB Master, ADB Segment, ADB Standby, etc.

IMPORTANT
Initially, there are no components on any of cluster hosts — the distribution of components between hosts should be performed manually.

The steps of adding components to hosts are listed below:

  1. From the CLUSTERS tab switch to the cluster configuring. To do this, click the row that contains the added cluster or click the icon in the Config column. Both methods open the cluster menu.

    Switching to cluster configuring
  2. Open the Hosts - Components tab in the cluster menu.

    NOTE
    The orange exclamation mark near the Hosts - Components menu item is displayed when the components distribution is needed.

    Switching to services components distribution
  3. In the opened window, distribute all necessary components between cluster hosts. To distribute components, use one of the ways:

    • Select a component in the Components column (by clicking at it) and then define all hosts for it in the Hosts column (by alternate clicking at each host).

    The typical scheme of components distribution for ADB clusters is described in the table below. It is based on the Enterprise Edition of ADB.

    Host Service Component Notes

    Master host

    ADB

    ADB Master

    Should be installed only on one Master host

    Chrony

    NTP Master

    Should be installed only on one Master host

    Secondary Master Host (Standby)

    ADB

    ADB Standby

    Should be installed on the Standby Master host

    Chrony

    NTP Secondary

    Can be installed optionally on the Standby Master host

    Segment host (1..N)

    ADB

    ADB Segment

    Should be installed on one or more Segment hosts

    Chrony

    NTP Slave

    Can be installed optionally on one or more Segment hosts

    PXF

    PXF

    Should be installed on one or more Segment hosts and, optionally, on the Master host

    ADCC/ADBM host

    ADCC

    ADCC server

    It is recommended to use a separate host for this component

    ADBM

    ADBM server

    Can be installed on the same host with ADCC server

    CAUTION
    Do not install ADCC server or ADBM server on the same host with the ADB Master or ADB Segment components. This feature is reserved for informational purposes only. Use a separate host for these components.
  4. After components distribution is completed, click Save.
