JVM 启动参数升级

远程 DEBUG 参数有所变化：

JAVA_DEBUG_OPTS=" -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:8000 "

打印 GC 日志参数的变化，我们在预发环境开启了日志进行观察：

JAVA_GC_LOG_OPTS=" -Xlog:gc*:file=/export/logs/gc.log:time,tid,tags:filecount=10:filesize=10m "

使用了 ZGC 的部分 JVM 参数：

JAVA_MEM_OPTS=" -server -Xmx12g -Xms12g -XX:MaxMetaspaceSize=256m -XX:MetaspaceSize=256m -XX:MaxDirectMemorySize=2048m -XX:+UseZGC -XX:ZAllocationSpikeTolerance=3 -XX:ParallelGCThreads=8 -XX:CICompilerCount=3 -XX:-RestrictContended -XX:+AlwaysPreTouch -XX:+ExplicitGCInvokesConcurrent -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/export/logs "
