Sizes, You need to configure the db_nK_cache_size parameters. These parameters are set to 0 by default. After these parameters are configured, you can specify the corresponding block when creating the relevant tablespace. This completes the Multiple Block Sizes. However, the Multiple Block Sizes provides a certain degree of complexity for the management proxy, so there is not much practical use. Note: When creating a non-db_block_size standard

Four ways to increase the size of table space in Oracle 1: Add data files to the table space ALTER tablespace App_Data ADD datafile ' D:\ORACLE\PRODUCT\10.2.0\ORADATA\EDWTEST\APP03. DBF ' SIZE 50M; 2: New data files, and allow

Reporting ORA-01658 when importing data to the orale Database: failed to create INITIAL partition error for segments in tablespace XXX. When I create a tablespace in Oracle, the initial size is 200 MB. When the data volume in the database reaches this value, an error is returned when I import data to the database. The solution is to expand the

tablespace during table creation. That is to say, if the user does not specify the tablespace during table creation, it is stored in the user-specified tablespace by default, however, if a tablespace is specified, other tablespaces can still be used. In addition, if other users are granted permissions, they can still

For Table space shrinking, Oracle only provides the extended function, but does not. Therefore, to achieve this requirement, you must first create an intermediate tablespace and then For Table space shrinking, Oracle only provides the extended function, but does not.
