HCL Workload Automation, Version 9.4

Configuring a master domain manager and backup master domain managers cluster

Configure a cluster including the master domain manager and backup master 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 master domain manager and backup master 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.

About this task

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

Procedure

  1. Optionally, create a virtual master domain manager extended agent workstation and add it to the database. For example:
    CPUNAME XA_VMDM
    		OS UNIX
    		NODE NotApplicable TCPADDR 31111
    		FOR MAESTRO HOST $MASTER ACCESS "unixlocl"
       TYPE X-AGENT
    		AUTOLINK OFF
    		BEHINDFIREWALL OFF
    		FULLSTATUS OFF
    	END
  2. Optionally, change the FINAL job stream to have all jobs run on the virtual master domain manager workstation.
  3. 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
  4. Optionally, create a dedicated mailman server ID for the communication with the backup master domain managers.
  5. In the TWAHome/TWS/localopts directory of the master domain manager and backup master domain manager instances, set the following:
    mm resolve master = no
    Appserver auto restart = no
  6. Copy TWAHome/TWS/config/SwitchPlan to TWAHome/TWS/SwitchPlan.
  7. Copy TWAHome/TWS/config/ResetPlan to TWAHome/TWS/ResetPlan.
  8. Uncomment the lines contained in the script files TWAHome/TWS/PreSwitchPlan and TWAHome/TWS/PostSwitchPlan.
  9. As user root, run TWAHome/TWS/TSAMP/createResources.sh on any of the following workstations:
    1. Backup master domain managers
    2. Master domain manager
