Server Configuration Next 18.7. Query Planning 18.7.1. Planner Method Configuration These configuration parameters provide a crude method of influencing the query plans chosen by the query optimizer. If the default plan chosen by the optimizer for a particular query is not optimal, a temporary solution is to use one of these configuration parameters to force the optimizer to choose a different plan. Better ways to improve the quality of the plans chosen by the optimizer include adjusting the planer cost constants (see Section 18.7.2 ), running ANALYZE...

References Download We have developed a FSQL Server for a Fuzzy Relational Database (FRDB). The FSQL language (Fuzzy SQL) is an extension of the SQL language that allows us to write flexible conditions in our queries. This Server has been depeloped for Oracle, following the model GEFRED, a theoric model for FRDB that includes fuzzy attributes to store vague information in the tables. The FSQL Server allows us to make flexible queries about traditional (crisp) or fuzzy attributes and we can use linguistic labels defined on any attribute. The FSQL language extends the SQL language to allow flexible queries. We have extended the SELECT command in order for it to express flexible queries and, due to its complex format, we only show here an abstract with the main extensions to this command: Linguistic Labels : If an attribute is capable of fuzzy treatment then linguisti...
As I was listening to Anil talk about daemons spawning processes and sysadmins killing them, I thought, "What a great user interface!" Imagine running around with a shotgun blowing away your daemons and processes, never needing to type kill -9 again. Sneaking up on my processes. In 1981, Vernor Vinge introduced the concept of cyberspace to the reading public in his novella True Names , <a href="truenames.html"> in which characters could plug into a virtual universe where their actions in a fantasy world mapped to performing sophisticated actions on the network. For example, walking along a tricky path through a swamp would be the same as going through a firewall. The mapping of abstract operations to an intuitive environment is a difficult problem. There are two distinct obstacles: the environment must be intuitive and the mapping must be accurate. If the environmen...
