Oracle BASICS (9) Oracle architecture and oracle infrastructure 1. Oracle Architecture Overview: Oracle architecture refers to the composition, working process and principle of the database, as well as the organization and management mechanism of data in the database. To und

In addition to supporting a variety of SQL statements, it also provides a variety of packages, stored procedures, and even supports features such as java and library Creation, such powerful functions

In 12c R1, you can now write DDL operations to XML and log files. This is for understandingIt is very useful who executed the Create or drop command at what time. To enable this function, the enable_ddl_logging initial parameters must be configured. This parameter can beSet at the database or session level. When this parameter is enabled, all

Let's take a simple look, there is a configuration file facility. lisFacilities_File = $ ORACLE_HOME/lib/facility. lisThe corresponding component needs to be obtained from this configuration file. For example, if we use the command oerr ora 12345, ora is the first parameter. Based on this parameter, we can obtain the component value that needs to be used next.The script contains the following line of similar c

specify different db_block_size values for different tablespaces. Therefore, the generation of row links is almost inevitable, and there is not much to adjust. Row migration is mainly because the pctfree parameter of the table is too small during table update, so there is not enough space in the block to accommodate the updated records, resulting in row migration. It is necessary for row migration to be adjusted because it can be adjusted and cleared. How can I check whether row migration and r
