row is returned, it indicates that the source tablespace is self-contained. Otherwise, it must be processed. In addition, the destination tablespace cannot contain sys objects.The source tablespace is read only.Although the source and target blocksize are not the same from 9i, if they are inconsistent, you need to add

In Oracle, I like Oracle tablespace very much. In my work, I also like to summarize the experience and lessons on Oracle tablespace. Let's talk about this in detail. Oracle tablespace i

Oracle modifies the Name of TableSpaceBefore Oracle10g, the name of tablespace cannot be modified at will. It can only be dropped and re-built. However, after 10g, oracle added the modification function, except for the system and sysaux tablespaces, other tablespaces can be renamed. We will record this feature today:An example of renaming

Oracle Database TableSpace and archive [SQL] -- TableSpace (TableSpace) is a pioneering concept of Oracle. Table space makes database management more flexible and greatly improves database performance. -- Function: 1. avoid the risk of sudden depletion of disk space 2. more

The table size has two meanings. One is the number of physical spaces allocated to a table, regardless of whether the space is used or not. You can query the number of bytes as follows: Select segment_name, bytesFrom user_segmentsWhere segment_type = 'table ';OrSelect segment_name, sum (bytes)/1024/1024 from user_extents group by segment_name Space actually used by another table. Query as follows: Analyze table EMP compute statistics;Select num_rows * avg_row_lenFrom user_tablesWhere table

In the data warehouse project, ETL is undoubtedly the most tedious, time-consuming, and unstable. If the data source and target are both Oracle and meet certain conditions, you can use the oracle tablespace to improve ETL efficiency.To use a tablespace, the following conditions must be met:The source and target databas

Database usage: oracle tablespace operations1. view the space used by the database table select tablespace_name, sum (bytes)/1024/1024 from dba_data_files group by tablespace_name;2. view the remaining tablespace in the database SELECT tablespace_name, sum (blocks * 8192/1000000) FROM dba_free_space group by tablespace_name;3.

can Perform the following steps: 1. Delete the data file. 2. Delete the tablespace.3. Recreate the index tablespace. 4. Recreate the index contained in the tablespace.1. You can restore tablespaces that only contain indexes without executing the RECOVER task. 2. If data files in tablespaces that only contain indexes are lost, it is easier to recreate the
