9.4 Setting up the threshold value to be used to control garbage collection

You can control the execution timings of full garbage collection of batch servers by setting up threshold values for memory usage. Hitachi recommends that the threshold value be set up when the same resources are accessed during batch processing and online processing. By setting up the appropriate threshold value, you can secure the throughput of both online processing and batch processing.

Hint
For details about the full garbage collection, see 7.1.3 Relation between the occurrence of garbage collection and memory space.
