    2 active datafiles in a tablespace

    Hi Friends,

    I have created a tablespace TS_IMAGE, and created two (2) datafiles associated to it, one on disk D: and the other on disk E: . Both drives(D,E) have other files/dirs created on it and are subject to run-out of space. Also both datafiles are created equally (same size, auto-extend, locally managed,etc).

    My question is are both datafiles active at the same time? If created a table or extend it, which datafile shall it go?

    Thanks a lot,

    A tablespace is nothing but a collection of datafiles which are nothing but a collection of datablocks.

    Looking at it from the logical point of view space for each one of your objects is organized in "extents" which are nothing but a collection of datablocks.

    At the time you create a table/index -or a table/index grows- you are allocating extents at the tablespace level letting Oracle to decide the datafile where to allocate the space you need.
