Sets The share of heap which you’re prepared to waste. The Java HotSpot VM doesn’t initiate the combined rubbish selection cycle in the event the reclaimable percentage is under the heap squander proportion. The default is five %.
If the process has more than one Model of Java, configure which just one your method takes advantage of by getting into the following command in a very terminal window
Sets the number of interpreted technique invocations before compilation. By default, from the server JVM, the JIT compiler performs ten,000 interpreted system invocations to assemble information and facts for effective compilation.
Linux only: Allows the usage of significant web pages that could dynamically improve or shrink. This option is disabled by default. It's possible you'll come upon efficiency problems with clear enormous internet pages because the OS moves other internet pages all around to generate huge web pages; this option is produced readily available for experimentation.
There's two sorts of 'InstallAnywhere' package accessible to you: the 'Archive/tgz' only extracts the files to your process, Whilst the 'Installable' package deal supposedly also configures your process.
hprof where pid is definitely the identifier of the process that induced the error. The subsequent instance reveals tips on how to set the default file explicitly (%p signifies The existing approach identifier):
Sets the period of time (in milliseconds) a softly reachable item is retained Energetic about the heap following the past time it had been referenced. The default value is a single next of lifetime per totally free megabyte while in the heap. The -XX:SoftRefLRUPolicyMSPerMB possibility accepts integer values symbolizing milliseconds for every one megabyte of the present heap dimension (for Java HotSpot Client VM) or the most possible heap size (for Java HotSpot Server VM).
Programs embedding the JVM frequently check out here should trap alerts such as SIGINT or SIGTERM, which can lead to interference With all the JVM sign handlers.
Logs messages tagged with at the least the gc and meta tags working with thetrace level to your file metatrace.txt but turns off all messages tagged with class.
Enables touching of each web page to the Java heap during JVM initialization. This will get all pages into memory just before getting into the principle() process.
Specifies a command to perform on a technique. For instance, to exclude the indexOf() technique of the String course from remaining compiled, use the following:
The JVM employs an analogous system to employ the attribute of dumping thread stacks for debugging reasons. The JVM works by using CTRL_BREAK_EVENT to carry out click here for more thread dumps.
To employ a different VM apart from the default, just incorporate the right choice to the command you site link Generally use. By way of example:
Sets the maximum code sizing (in bytes) for compiled solutions that needs to be inlined. Append the letter k or K to point kilobytes, m or M to indicate megabytes, or g or G to indicate gigabytes.
