JVM on which managed server (on which BPEL engine is running) is running

should choose garbage collection strategy which optimizes application throughput.

If BPEL engine is hosting short running synchronous processes only and load on

server is constant (not varying within short interval of time), deterministic

strategy might be better option.

BPEL /.

A good value for the compact ratio is usually between 1 and 20, sometimes even

higher. Compaction ratio must be in tune with compact set limit.

Low value of compaction ratio may increase the fragmentation and the amount of

free space that is too small to be used for object allocation.

-XXcompactSetLimit:A , 10,000 . I

,

.

A normal value for the compact set limit is usually between 100,000 and several

million, while lower values are used when the pause time limits are very low.

Setting the compact set limit too low may stop compaction from being done

altogether. Running without any compaction at all may lead to increasing

fragmentation, which will in the end force the JVM to perform a full compaction of

the whole heap at once, which may take several seconds.

Typically the preferred TLA size can be up to twice the size of the largestcommonly used object size in the application. Adjusting the min size may have

an effect on garbage collection performance, but is seldom necessary. A normalvalue for the min size is 2 KB.

Increasing the TLA size is beneficial for BPEL Engine and hence deployed

processes/composites (since BPEL engine is a multi-threaded applications and

each thread allocates a lot of objects and size of objects is large). Increasing the

TLA size too much may however cause more fragmentation and more frequentgarbage collections.

Parallel GC strategy (with or without compaction) is designed for small to medium

scale applications.

The concurrent GC strategy, as name suggests does most of its work whileapplication is running, so minimizes pause time. This strategy focuses on responsetime rather than over all throughput.
