Documentation
Definition
The daemon interval controls the period in seconds of the selection run of the background process, the RAL daemon. It is responsible for the RAL records, which have been put into the shared memory by the work processes representing a communication channel.
Use
The interval is the minimal waiting time before the daemon starts browsing the shared memory which is reserved by the RAL runtime.
Dependencies
After a selection run at the Shared memory, the daemon calculates the time used for this loop. The difference between the time used and the interval value is used for a WAIT in seconds afterwards. Is the difference is negative or zero no WAIT is done. A value much greater than the recommend value, may lead to a Shared memory overflow.
Example
The standard value is 10. The minimum value is 1 and the maximum value allowed is 300. The optimal value may depend on the number of processes which are involved and the size and number of entries which are written by each communication channel. There is no formula to get the best value, a useful hint may be got from the size of the shared memory area named CL_SRAL_SHM_DATA_AREA.
