You don t have to allocate all the buffer cache memory to a single pool As 10 showed you, you can use three separate pools: the keep buffer pool, the recycle buffer pool, and the default buffer pool Although you don t have to use the keep and default buffer pools, it s a good idea to configure all three pools so you can assign objects to them based on their access patterns In general, you follow these rules of thumb when you use the multiple buffer pools: Use the recycle cache for large objects that are infrequently accessed You don t want these objects to occupy a large amount of space unnecessarily in the default pool Use the keep cache for small objects that you want in memory at all times Oracle automatically uses the default pool for all objects not assigned to either the recycle or keep cache.

Since version 81, Oracle has used a concept called touch count to measure how many times an object is accessed in the buffer cache This algorithm of using touch counts for managing the buffer cache is somewhat different from the traditional modified LRU algorithm that Oracle used to employ for managing the cache Each time a buffer is accessed, the touch count is incremented A low touch count means that the block isn t being reused frequently, and therefore is wasting database buffer cache space If you have large objects that have a low touch count but occupy a significant proportion of the buffer cache, you can consider them ideal candidates for the recycle pool Listing 20-5 contains a query that shows you how to find out which objects have a low touch count.

Interaction Overviews can contain any mixture of symbols from Activity, Sequence, and Communication diagrams. While Activity diagrams are good at representing business processes, Sequence and Communication diagrams are better at showing the timing details of specific use cases.

You can embed two distinct kinds of resources in a managed PE file: unmanaged platformspecific resources and managed resources specific to CLR. These two kinds of resources, which have nothing in common, reside in different sections of a managed image file and are accessed by different sets of APIs.

The preceding query shows you that three objects, each with a low touch count, are taking up about 20 percent of the total buffer cache. Obviously, they re good candidates for the recycle buffer pool. In effect, you re limiting the number of buffers the infrequently used blocks from these three tables can use up in the buffer cache. The following query on the DBA_OBJECTS view gives you the names of the objects:

Component Wiring diagrams are new to UML 2. They use the so-called lollipop symbol to represent interfaces exposed by a component. A lollipop symbol contains a small circle connected to a line. Component Wiring diagrams make the assumption that all outgoing calls are interface-based in other words, made using the notation object.method, where object implements some interface. Outgoing calls connect to lollipops using a special connector symbol that wraps around one side of the lollipop circle, as shown in Figure 6-16.
