How to know the default threadpoolsize
How do i check the threadpoolsize configured in my system.
I don't find it in my prconfig file or my DASS.

If it is not configured in prconfig or DASS then default will be 5.
Let us know if this helps.

What can be the limit of the thread pool size..
How do i calculate the threadpool size based on the hardware available?

Also where can i get such default values.. Do we have any document available?

Hi,
The number of threads is determined by the agent/threadpoolsize and services/maxrequestorchildren environment settings that you configure in the prconfig.xml file.
-
Open the prconfig.xml file from the application server.
-
Add the following configuration:
<env name="agent/threadpoolsize" value="xx" /><env name="services/maxrequestorchildren" value="xx" />

Save your changes and upload the prconfig.xml file to the application server.
threadpoolsize
Type: integer
Default: 5
Functionality: This setting entry adjusts the size of the batch requestor
pool, to provide the number of available Java threads on
which agents and batch requestors may run. The maximum number of threads is limited by the operating system
considerations.
maxRequestorChildren
Type: integer
Default: 10
Functionality: This setting limits the number of child requestors that can be
created for asynchronous connection processing. Ex: Run in Parallel in connectors or asynchronous API.
So the child requestors are batch requestors used for:
- explicitly started through the queueBatchActivity method in publicAPI
- implicitly started through the "run in parallel" option on Connect-SOAP, Connect-HTTP, Connect-REST, Connect-MQ, Connect-JMS and Connect-EJB activity methods.
- explicitly started through activity method Queue
- implicitly started through a parallel option in rule-declare-trigger
So - with the batch thread pool set at 200 you are allowing your PRPC server to run up to 200 agents and child requestors at the same time.
With maxRequestorChildren set to 100, you are allowing one requestor to have up to 100 explicit and implicit child requestors at the same time.
If you have more child requestor requests than threads, the child requests wait.
