You can see where your database’s archived redo goes as follows:

SQL> l
  1  select value from v$parameter
  2* where name = 'log_archive_dest'
SQL> /

VALUE
------------------------------
/old_dir/arch

SQL>

And you can see them on disk too:

SOLARIS > /old_dir > ls -1 *arc
arch8190_TEST11_1_705064488.arc
arch8191_TEST11_1_705064488.arc
arch8192_TEST11_1_705064488.arc
arch8193_TEST11_1_705064488.arc
arch8194_TEST11_1_705064488.arc
SOLARIS > /old_dir >

You can send archived redo to a new location like this:

SQL> alter system set log_archive_dest =
  2  '/new_dir/arch'
  3  scope = both;

System altered.

SQL>

When you have done this you should always test that the archiving is working:

SQL> alter system switch logfile;

System altered.

SQL> /

System altered.

SQL> /

System altered.

SQL>

And check in the operating system that the files are arriving:

SOLARIS > /new_dir > ls -1 *arc
arch8195_TEST11_1_705064488.arc
arch8196_TEST11_1_705064488.arc
arch8197_TEST11_1_705064488.arc
SOLARIS > /new_dir >
