CodeCache是Java虚拟机(JVM)中的一部分,用于存储即时编译器(JIT)编译生成的本地机器码。JIT编译器会在运行时将热点字节码(即频繁执行的代码)编译为机器码,以提高执行效率。CodeCache的主要作用是存储这些编译后的机器码,以便快速执行。 2. “CodeCache is full”错误的可能原因 当CodeCache中的空间不足以存储更多...
OpenJDK 64-Bit Server VM warning: Try increasing the code cache size using -XX:ReservedCodeCacheSize= 程序虽然能跑起来,但这提示意味着 JIT 编译被关闭了,性能可能会受到影响,特别是对于大型或长时间运行的服务来说,得引起重视。 二、报警信息解析 关键提示内容如下: CodeCache is full. Compiler has bee...

The default maximum size of the CodeCache on most of the platforms is 48M. If any application needs to compile large number of methods resulting in huge amount of compiled code then this CodeCache may become full. When it becomes full, the compiler is disabled to stop any further ...
这条命令将会将 CodeCache 的大小设置为 128MB。根据实际情况,可以根据警告信息中的大小进行调整。 步骤4:重新启动应用程序 完成上述步骤后,重新启动应用程序即可生效。 总结 通过以上步骤,我们可以解决 “Java HotSpot™ 64-Bit Server VM warning: CodeCache is full. Compile” 警告。通过增加 CodeCache 大小、...

分析Java HotSpot(TM) 64-Bit Server VM warning: CodeCache is full. Compiler has been disabled. 近期在使用Java HotSpot(TM) 64-Bit Server VM时,你可能会遇到类似以下的警告信息: plaintextCopy codeJava HotSpot(TM) 64-Bit Server VM warning: CodeCache is full. Compiler has been disabled. ...
其中CodeCache is full,说明Code Cache已经满了,导致Compiler失效,这是为什么? 首先,我们得了解什么是Code Cache。 什么是Code Cache Java代码在执行次数达到一个阈值会触发JIT编译,一旦代码块被编译成本地机器码,下次执行的时候会直接运行编译后的本地机器码。所以这本地机器码必须被缓存起来,而缓存这个本地机器码...
