| <p>For a detailed description of the policies, when to use them, and how they work, see <a href="../gc/">Garbage Collection policies</a>. The following GC policies are available:</p> |
| <h3 id="gencon"><code>gencon</code></h3> |
| <pre><code> -Xgcpolicy:gencon |
| </code></pre> |
| <dl> |
| <dd>The generational concurrent policy (default) requires a heap that is divided into two main areas (<em>nursery</em> and <em>tenure</em>) to manage two generation groups (<em>new</em> and <em>older</em>). The policy uses a global GC cycle of concurrent <em>mark-sweep</em> operations, optionally followed by <em>compact</em> operations. The policy also uses a partial GC cycle to run <em>scavenge</em> operations on the <em>nursery</em> area. The partial cycle helps reduce the frequency and duration of the global GC cycle. Note that <em>scavenge</em> is a <em>stop-the-world</em> operation, unless <code>-Xgcpolicy:gencon</code> is specified with the <a href="../xgc/#concurrentscavenge"><code>-Xgc:concurrentScavenge</code></a> option.</dd> |
| <dd>To learn more about this policy, when to use it, and how it works, see <a href="../gc/#gencon-policy-default">Garbage collection: <code>gencon</code> policy</a>.</dd> |
| </dl> |
| <h3 id="balanced-64-bit-only"><code>balanced</code> (64-bit only)</h3> |
| <pre><code> -Xgcpolicy:balanced |
| </code></pre> |
| <dl> |
| <dd>The Balanced policy requires a multi-region heap to manage multiple generations of objects. The policy uses a global GC cycle that involves an incremental concurrent <em>mark</em> operation (global mark phase), followed by <em>stop-the-world</em> (STW) <em>sweep</em> operation. The policy also uses a partial GC cycle to run <em>copy forward</em> or <em>mark-compact</em> operations. Regions are individually managed to reduce the maximum pause time on large heaps and increase the efficiency of garbage collection. The policy tries to avoid global collections by matching object allocation and survival rates. With the <code>balanced</code> policy, the global mark and partial GC cycles interleave. The global STW <em>sweep</em> operation runs within the same GC increment as the first partial GC cycle that follows the global mark phase.</dd> |
| <dd>The <code>balanced</code> policy also exploits large systems that have Non-Uniform Memory Architecture (NUMA) characteristics (x86 and POWER™ platforms only), which might further improve application throughput.</dd> |

| <p>The <em>optimize for pause time</em> policy requires a <em>flat</em> heap and uses a global GC cycle to run concurrent <em>mark-sweep</em> operations, optionally followed by <em>compact</em> operations. Pause times are shorter than with <code>optthruput</code>, but application throughput is reduced. The impact on throughput occurs because some garbage collection work is taking place in the context of mutator (application) threads, and because GC frequency is increased.</p> |

| <p>The <em>optimize for throughput</em> policy requires a <em>flat</em> heap and uses a global GC cycle to run <em>mark-sweep</em> operations, optionally followed by <em>compact</em> operations. Because the application stops during a global GC cycle, long pauses can occur.</p> |

| <p>The metronome policy is an incremental, deterministic garbage collector with short pause times. Applications that are dependent on precise response times can take advantage of this technology by avoiding potentially long delays from GC activity. The <code>metronome</code> policy is supported on specific hardware and operating system configurations.</p> |
| <p>To learn more about this policy, how it works, and when to use it, see <a href="../gc/#metronome-policy">Garbage collection: <code>metronome</code> policy</a>.</p> |

| <pre><code> -Xgcpolicy:nogc |

| <dl> |
| <dd> |
| <p>This policy handles only memory allocation and heap expansion, but doesn't reclaim any memory. If the available Java heap becomes exhausted, an <code>OutOfMemoryError</code> exception is triggered and the VM stops.</p> |
| <p>You should be especially careful when using any of the following techniques with <code>nogc</code> because memory is never released under this policy:<br /> |
| - Finalization<br /> |
| - Direct memory access<br /> |
| - Weak, soft, and phantom references</p> |
| </dd> |
| <dd> |
| <p>To learn when to use this policy, see <a href="../gc/#nogc-policy">Garbage collection: <code>nogc</code> policy</a>.</p> |
| </dd> |
| </dl> |
| <p>This policy can also be enabled with the <a href="../xxusenogc/"><code>-XX:+UseNoGC</code></a> option.</p> |
