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

Zlib is a data compression library that is designed to handle simple data (regardless of the source of the data). Gzip is a file compression tool (or the compressed file format produced by the compression tool) that is designed to work with individual files. Gzip uses zlib to compress data in a file. In order to save information about file attributes, Gzip needs

Back to directory It is very necessary to compress the header of a webpage when the page size is large. This will significantly reduce the page size and increase the speed at which the webpage is downloaded from the server to the client, here is a test I did: When Header Compression is not used: After header compression is used: We can see that the size of the web page is reduced by 6 kb, whic

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.
