You can use simple ratios to see if your library cache is sized correctly. The V$LIBRARYCACHE data dictionary view provides you with all the information you need to see whether the library cache is efficiently sized. Listing 20-1 shows the structure of the V$LIBRARYCACHE view. Listing 20-1.

In the field of hardware control systems, feedback denotes any output signal that is routed back as an input. For example, given a system that provides analog signal amplification, feedback is a portion of the output signal that is taken and fed back into an input, as shown in Figure 9-6. how to print barcode in asp net c# Barcode generation scan free for ASP.NET aspx, Visual C#, Java ...

The following formula provides you with the library cache hit ratio: SQL> SELECT SUM(pinhits)/sum(pins) 2 FROM V$LIBRARYCACHE; LIBRARY_CACHE_HIT_RATIO -----------------------.993928013 SQL> The formula indicates that the library cache currently has a higher than 99 percent hit ratio, which is considered good. However, be cautious about relying exclusively on high hit ratios for the library cache and the buffer caches, such as the one shown here. You may have a hit ratio such as 99.99 percent, but if significant waits are caused by events such as excessive parsing, you re going to have a slow database. Always keep an eye on the wait events in your system, and don t rely blindly on high hit ratios such as these. Listing 20-2 shows how to determine the number of reloads and pinhits of various statements in your library cache. Listing 20-2. Determining the Efficiency of the Library Cache SQL> SELECT namespace, pins, pinhits, reloads 2 FROM V$LIBRARYCACHE 3 ORDER BY namespace; Library_cache_hit_ratio NAMESPACE -----------------BODY CLUSTER INDEX JAVA DATA JAVA RESOURCE JAVA SOURCE OBJECT PIPE SQL AREA TABLE/PROCEDURE TRIGGER 11 rows selected.

Digital signal filters, known as infinite impulse response filters, use a digital form of feedback to achieve impressive filtering characteristics with relatively simple algorithms. Feedback has also been used in software systems for quite some time. Given a system in which one object calls another, I ll use the word feedback to denote any information returned from the callee back to the caller, during or at the end of an asynchronous operation. When feedback is used only to signal the end of an asynchronous operation, it is sometimes referred to as a completion token.3 While feedback can conceptually be used in purely synchronous systems, it is much more common in asynchronous ones. In asynchronous interactions, the caller might be interested in something about the progress or outcome of commands sent to the callee, such as the following: How far along the command is How much more time the command will take When the command has been completed The outcome of the command When the caller requires feedback, there must exist a separate communication channel to get it from the callee. There are two ways for a caller to get feedback from the callee: 1. The callee pushes feedback to the caller. 2. The caller pulls feedback from the callee. I ll describe each case in more detail.
