I receive from the RPC Server the error message
02150129 NOT ENOUGH SPACE FOR COMMUNICATION BUFF
These are the main parameters:
The value of MAXBUFF=4992 leads to the above mentioned error 02150129 in the main task. Manual: RPCSIZE=MAXBUFF+8
When I reduce MAXBUFF to 4700, I receive the error 02150129 in the 4th subtask.
The error message means that the NUM-COMBUF value in the Broker is set too small. But NUM-COMBUFF is set in the Broker version 8 to 2000.
From the Maunual:
"The NUM-COMBUFF value determines the maximum number of communication buffers that can be processed by the Broker in parallel.
The size of one communication buffer is usually 16 kBytes split into 32 slots of 512 bytes, but it ultimately depends on the hardware architecture of our CPU.
The data to be transmitted to the Broker and back to the application has to be exchanged between the Broker engine and the PSTORE (Broker Worker) process. A communication buffer is used to store the send data as well as the reply data of all requests that are active in parallel. As soon as the desired data is sent to the target application, the buffer is released."
