Explanation/Reference: Explanation: The Oracle docs note this on the ora-01653 error: ORA-01653: unable to extend table string.string by string in tablespace string Cause: Failed to allocate an extent of the required number of blocks for a table segment in the tablespace indicated. Action: Use ALTER TABLESPACE ADD DATAFILE statement to add one or more files to the tablespace indicated. Oracle MOSC Documents offer great resources on resolving ORA-01653, namely the nature of the problem as it relates to space availability: ------------ This error does not necessarily indicate whether or not you have enough space in the tablespace, it merely indicates that Oracle could not find a large enough area of free contiguous space in which to fit the next extent. Diagnostic Steps: ----------------- 1. In order to see the free space available for a particular tablespace, you must use the view DBA_FREE_SPACE. Within this view, each record represents one fragment of space. How the view DBA_FREE_SPACE can be used to determine the space available in the database is described in Note 121259.1 Using DBA_FREE_SPACE Furthermore, MOSC offers these choices in resolving ORA-01653 (as quoted below): Manually COALESCE Adjacent Free Extents Add a DATAFILE Resize DATAFILE Enable AUTOEXTEND Defragment tablespace View temporary segments for space
