Location of the table space files?

Question

How can I find the directory in which oracle stores it's table space files?

When I do: select * from dba_data_files; or select * from v$datafile; then I get some paths like that:

+DATA01/fu/datafile/bar_ts01_data.260.264360912

But what means +DATA01? And where is that exactly in the file system?

Answer 1

+DATA01/fu/datafile/bar_ts01_data.260.264360912

Yes this is correct file path. It means you use ASM disk.

After you login to OS with "grid" user [usually Oracle Grid Infrastructure installation user is named like that], run following command to browse files on ASM disk.

export ORACLE_HOME=/u01/app/11.2.0/grid --this is also usual installation dir, may differ on your case
export ORACLE_SID=+ASM
cd $ORACLE_HOME/bin
./asmcmd -p
ASMCMD>ls
+DATA01
+DATA02
ASMCMD>cd +DATA01
