What Ruth describes is "tablespace point in time recovery" or incomplete recovery. I believe the question was about performing complete recovery on a single tablespace while the rest of the database is in use. (I could be wrong in this assumption.)
If a single tablespace (other than SYSTEM!) needs complete recovery, then: 1) SQL> alter tablespace BAD_ONE offline; 2) restore corrupted tablespace datafile(s) from backup 3) restore archive log(s) from backup if necessary 4) SQL> recover tablespace BAD_ONE; 5) SQL> alter tablespace BAD_ONE online; While this is happening, object in other tablespaces are fully accessible, except that there may be some issues with objects in other tablespaces that reference objects in the BAD_ONE tablespace (e.g. foreign key constraints referencingtables in BAD_ONE, tables in other tablespaces with CLOBs stored out-of-line in BAD_ONE, tables with primary or unique key constraint indexes in BAD_ONE, etc.). There are a few variations on the theme for step 5 - for example, "recover datafile" perhaps if all the datafiles for the tablespace are not corrupted.

How DO you do an online recovery of a datafile while the database is still in use? I've had to do recoveries before, but never this scenario.
