If you use a multi node scenario, you can optimize the load balancing of your system.
Prerequisite
The PROCESS_INSTANCE_BASED assignment strategy is configured for Process Governance.
You can configure the rebalancing of Process Governance nodes using ARIS Cloud Controller (ACC). ACC is a command-line tool for administrating and configuring an ARIS installation. It communicates with ARIS Agents on all nodes. For details please refer to ARIS Cloud Controller (ACC) Command-Line Tool.pdf.
By default, the rebalancing is enabled. When adding a new node and activate it, the process instances from default tenant will be equally distributed to each node automatically.
Disable rebalancing on all nodes
Procedure
on all nodes stop <Process Governance instance>, for example, on all nodes stop apg_m
Enter on all nodes reconfigure<Process Governance instance> "JAVA-Dcom.idsscheer.age.node.rebalance"="false", for example, on all nodes reconfigure apg_m "JAVA-Dcom.idsscheer.age.node.rebalance"="false".
on all nodes start <Process Governance instance>, for example, on all nodes start apg_m.
You have disabled the rebalancing of Process Governance.
When adding a new node and activate it, the process instances are not distributed automatically among all active nodes. Adding the new node has no impact on the performance of the system.
Disable rebalancing on a specific Process Governance instance
Procedure
stop <Process Governance instance> on node <server>, for example, stop apg_m2 on node myserver1 or stop apg_m1 on node myserver2.
start <Process Governance instance> on node <server>, for example, start apg_m2 on node myserver1 or start apg_m1 on node myserver2.
You have disabled the rebalancing of a specific Process Governance instance.
When adding a new node and activate it, the process instances are not distributed automatically among all active nodes. Adding the new node has no impact on the performance of the system.
Enable rebalancing on all nodes
Procedure
You have enabled the rebalancing of Process Governance.
When adding new node and activate it, the process instances from default tenant will be equally distributed to each node automatically.
Enable rebalancing on a specific Process Governance instance
Procedure
You have enabled the rebalancing of a specific Process Governance instance.
When adding new node and activate it, the process instances from default tenant will be equally distributed to each node automatically.
