Configuring a dynamic domain manager and backup dynamic domain managers cluster

Configure a cluster including the dynamic domain manager and backup dynamic domain managers.

Before you begin

Before configuring the cluster, ensure that the following prerequisites are met:

Tivoli System Automation for Multiplatforms V3.2.2 Fix Pack 7 or later is installed on the dynamic domain manager and backup dynamic domain manager instances.
For detailed information about how to install and configure a cluster, see the Tivoli System Automation for Multiplatforms: Installation and Configuration Guide. For detailed information about how to implement high availability for HCL Workload Automation, see Redbooks Tivoli Integration Scenarios.
The Tivoli System Automation for Multiplatforms peer domain TWS is online and the quorum type of the peer domain is set to QuorumLess.
HCL Workload Automation V8.6 Fix Pack 2 or later is installed on the master domain manager and backup master domain manager instances.

Note: During the configuration, all HCL Workload Automation components are restarted.

To configure the dynamic domain manager and backup dynamic domain managers cluster, perform the following steps:

In the TWAHome/TWS/localopts directory of the dynamic domain manager and backup dynamic domain manager instances, set the following:
```
Appserver auto restart = no
```
Optionally, if the DB2 HADR pair is part of the Tivoli System Automation for Multiplatforms cluster, update the following datasource properties by using the TWAHome/wastools/changeDataSourceProperties.sh script:
```
DB2Type4ServerName=Virtual IP Address of the HADR pair
DB2Type4DbFailOverEnabled=true
```
Optionally, create a dedicated mailman server ID for communication with the backup dynamic domain managers.
