Basicjavaswitches Option

Introduced in release: 8.0.2

Updated in release: 8.0.2.2

The  ISC option specifies a space-separated list of JVM options (heap settings, GC options, etc) to use when starting the java isc process. The default settings for this option are the recommended JVM switches for running ISC, described below. The recommended JVM switches may change between releases as Oracle gains tuning experience with ISC. Unless the customer determines one of the recommended JVM switches is inappropriate for their environment changes to this option are discouraged as an explicit setting means future changes to the recommended defaults will not be applied. The  option can be used to append customer preferred JVM switches without replacing the recommended default settings. -Xms8g -Xmx32g -XX:+UseG1GC -XX:MaxGCPauseMillis=200 Changes to this option do not take effect until ISC is restarted.
