TransientCacheSizeLimit

Integer (prefix multiplier)

40M

Purpose

The TransientCacheSizeLimit parameter specifies the maximum amount of memory that is allocated by the JADE client node for caching transient objects in the client machine.

The optimum value for this parameter varies, depending on the amount of physical memory available on the client machine and the size of the working set of transient objects that are accessed frequently.

The minimum value is 3M bytes and the maximum value is two‑thirds of the physical memory on the client machine (with a maximum of 4G bytes on 32‑bit JADE systems).

When JADE detects a parameter value that is outside the allowed range, the value is changed to be the appropriate minimum or maximum, a message is output to the jommsg.log file, and the JADE initialization file is updated. Node initialization then continues normally.

Parameter is read when …

The application server or the standard (fat) client node is next initialized.

Hint

Use the transientCacheStats or remoteTransientCacheStats parameter in the logObjectCaches method of the Node or System class to log statistics of the transient objects cache usage.

Increasing the value of the TransientCacheSizeLimit parameter may reduce cache misses. (For details about sampling JADE nodes to obtain statistical information, see Chapter 4 of the JADE Object Manager Guide.)
