RE: Resize Tablespaces
hi,

We can resize the datafiles which in turn resize the tablespace for which the datafile belongs. The command is

alter database datafile '<datafile_name>'  resize(size)M;

By this command the datafile size will increase and intrun the tablespace size.

We can add the datafiles to the tablespace to increase the size of the tablespace. The command is

alter tablespace <tablespace_name> add datafile <datafile_name>' size(size)m;
