Configuring WIS RPC Request Processing

To process RPC requests, both the WIS and WQS processes access a pool of “worker” threads, that is provided by a multi-threaded RPC server shared library (SWRPCMTS). You can use the RPC_SVR_NUM_THREADS process attribute to define the number of threads that are available in the SWRPCMTS library to process RPC requests.

You can adjust the value of this process attribute to optimize the WQS and WIS process’ response times when processing RPC requests against available CPU capacity. Increasing the number of threads will improve the throughput of client RPC requests, but at the cost of increased CPU usage.

Note: The RPC processing threads perform their work independently of and concurrently with the queue update thread. In pre-10.4 versions of iProcess Engine, where the WIS process was single-threaded, the WIS process had to switch between processing RPC requests and updating work queues.
