Compression capabilities for Oracle databasesEveryone heard this word, must have thought of saving hard disk space it. Yes, it is used to do this, but to extend it, it can not only save hard disk space, but also save bandwidth and memory usage (CPU has a little bit of loss because of the need for more compute value operation, but because most of the environment the CPU is idle, so it can be ignored).Basiccompression This feature is available from 9i o

Tomcat configuration gzip compression, tomcatgzip CompressionHTTP compression can greatly improve the speed of website browsing. The principle is that after the client requests a web page, the server compresses the web page file and downloads it to the client, the client browser is responsible for Uncompressing and browsing. Compared with ordinary browsing processes such as HTML, CSS, Javascript, and Text,

Before using compression, we can estimate the effect of compression.Dbms_comp_advisor can be used before 11gr2. The specific code is provided in the attachment. You only need to execute two files, dbmscomp. SQL and prvtcomp. plb, and then use the DBMS_COMP_ADVISOR.getratio stored procedure. It is not described in detail.
