Hello,
dafafile this oracle like this example. can be added to another hdd.
ALTER TABLESPACE lmtbsb
ADD DATAFILE '/u02/oracle/data/lmtbsb02.dbf' SIZE 1M;
ALTER TABLESPACE lmtbsb
ADD DATAFILE '/u03/oracle/data/lmtbsb02.dbf' SIZE 1M;
ALTER TABLESPACE lmtbsb
ADD DATAFILE 'e:\data\lmtbsb02.dbf' SIZE 1M;
ALTER TABLESPACE lmtbsb
ADD DATAFILE 'f:\data2\lmtbsb02.dbf' SIZE 1M;
i understand about that LVM solution. it is true that using this method can
be done. I'm just asking for a solution at the database level.
thank you
Yours faithfully
