You need to UNSET db_create_file_dest on the standby as it overrides
db_file_name_convert. DB_FILE_NAME_CONVERT will get ignored.
DB_CREATE_FILE_DEST will also create oracle managed file names (OMF
filenames) as you see getting done in your example.
Then you need to make sure your DB_FILE_NAME_CONVERT parameter is set
CORRECTLY to properly place the datafile in the right place.
So on db_file_name_convert should be something like:
IF primary location = /oracle/data/DGRDTSTD/DGRDTSTD/datafile
Then db_file_name_convert on standby should be:
db_file_name_convert=' DGRDTSTD/DGRDTSTD',' DGRDTSTC/DGRDTSTC' ;
Your db_file_name_convert *must *properly set the full string you want to
replace with the string you want to use as the replacement value.

We’ve set up data guard with a primary and a secondary. The primary is
DGRDTSTD. The secondary is DGRDTSTC. We are running Oracle 19c on Linux
Red Hat 7.
If I create a new data file on the primary, it creates it on the
secondary, but in the wrong directory. It creates a new directory, called
DGRDTSTD and puts the new file there, instead of putting it in the DGRDTSTC
directory. I can move it and rename it, but I shouldn’t have to.
I tried to set the db_create_file_dest parameter on both databases:
on the standby:
alter system set db_create_file_dest='/oracle/data/DGRDTSTC';
on the primary:
alter system set db_create_file_dest='/oracle/data/DGRDTSTD';
All that did was to create the new file as:
/oracle/data/DGRDTSTC/DGRDTSTC/datafile/o1_mf_test_dat_jj2xgght_.dbf
The original file name was test_data_enc03.dbf. I don’t know why it
changed it.
What do I have to do to get the secondary to create the new data file in
the correct directory (/oracle/data/DGRDTSTC) and do it right?
