Description

This object specifies the size of the memory area to reserve in shared memory to hold the compiled representation of user-defined filters. The memory size is specified in bytes. Filters are used by the Queuing Services component of the BEA Engine for message selection in dequeuing and cursor operations. Filters can be specified using various grammars, but are compiled into an engine normal form and stored in shared memory. Filters are referenced by a handle that is returned when they are compiled. When a filter is destroyed, the memory used by the filter is made available for subsequent compiled filters. When the filters are defined by an application, the administrator must configure the system to accommodate the maximum number of filters that will be concurrently compiled. An operation fails if a user attempts to create a new filter and there is not enough memory allocated for the compiled version of the filter. Adjusting this value has no effect on Tuxedo applications other than unnecessarily consuming shared memory resources.
