Scope: managed applications, ordinary applications.
The system creates a special cache of data access restriction queries to improve performance of data receiving queries when restrictions apply. Data access restrictions can be used by session parameters and functional options. The cache includes data restriction queries with set values of session parameters and functional options.
When changing values of session parameters or functional options used in data access restriction queries, the query cache is cleared. It results in a considerably lower performance of data queries.
We recommend that you set session parameter values "on demand" in the SessionParametersSetting handler of the session module. We do not recommend that you frequently change functional option values.
