Question
What are the recommended values for Maximum Threads on IBM TRIRIGA Admin Console Thread Manager page?
Cause
Need to set up Maximum Threads for better performance without causing problems to my system.
Answer
To control the number of threads that are started for each agent, use the Threads Manager menu in the IBM TRIRIGA Administrator Console.
A single thread requires one connection to the database.
A large value for the total of maximum threads can slow performance. As a guide line, a typical limit is no more that 2 to 3 times the core count of the database server. One must also add the number of servers and agents connected to the database. If there are multiple Workflow Agents running against the same database, the sum total threads across all servers should not be more than 2 to 3 times the total core count of the database.
Reminding here that the only scenario recommended for having multiple Workflow Agent instance running is when you have a User List associated to them. See more information here: When to use Multiple Workflow Agents
For example, if the database has two Dual Core Xeon CPUs, the core CPU count is four (4 CPUs). So, you should have up to 12 threads connecting to the database (3 x 4 CPUs). You have only a process server with a single Workflow Agent instance running as part of your topology. On such content, you may share the 12 threads this way when setting Maximum Threads on IBM TRIRIGA Admin Console -> Threads Manager:
CadIntegrator - 2
DataImportAgent - 2
SchedulerAgent - 2
WFAgent - 4
ReportQueueAgent - 2
