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:
-
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 -
Open the Hosts - Components tab in the cluster menu.
NOTEThe orange exclamation mark near the Hosts - Components menu item is displayed when the components distribution is needed.
Switching to services components distribution -
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).
Choosing hosts for a component -
Select a host in the Hosts column (by clicking at it) and define all components for it in the Components column (by alternate clicking at each component).
Choosing components for a 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.
ADB components distribution 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
CAUTIONDo 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. -

After components distribution is completed, click Save.
