15.2. Configure Lock Striping (Remote Client-Server Mode)
Lock striping in Red Hat JBoss Data Grid's Remote Client-Server mode is enabled by setting the
striping element to true.
Example 15.1. Lock Striping (Remote Client-Server Mode)
<locking acquire-timeout="20000" concurrency-level="500" striping="true" />
<locking acquire-timeout="20000"
concurrency-level="500"
striping="true" />Note
The default isolation mode for the Remote Client-Server mode configuration is
READ_COMMITTED. If the isolation attribute is included to explicitly specify an isolation mode, it is ignored, a warning is thrown, and the default value is used instead.
The
locking element uses the following attributes:
- The
acquire-timeoutattribute specifies the maximum time to attempt a lock acquisition. The default value for this attribute is10000milliseconds. - The
concurrency-levelattribute specifies the concurrency level for lock containers. Adjust this value according to the number of concurrent threads interacting with JBoss Data Grid. The default value for this attribute is32. - The
stripingattribute specifies whether a shared pool of locks is maintained for all entries that require locking (true). If set tofalse, a lock is created for each entry. Lock striping controls the memory footprint but can reduce concurrency in the system. The default value for this attribute isfalse.
