9.4 Setting the thresholds for GC control
You can control the execution timings of Full GC 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.
