ORA-01264: Unable to create datafile file name ORA-19800: Unable to initialize Oracle Managed Destination

ORA-01264: Unable to create datafile file name
ORA-19800: Unable to initialize Oracle Managed Destination

Error Description:
----------------------------------
 ERROR at line 1:
ORA-01264: Unable to create datafile file name
ORA-19800: Unable to initialize Oracle Managed Destination
Solaris-AMD64 Error: 13: Permission denied

Or in linux the error stuck is,

SQL> alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:
ORA-01264: Unable to create logfile file name
ORA-19800: Unable to initialize Oracle Managed Destination
Linux Error: 13: Permission denied

Cause of The problem:
-------------------------------------
The user don't have the permission to write in the specified location. This is Operating system permission. I got this error while duplicating the database from from backup location. in my case the exact cause is I forgot to mention the db_recovery_file_dest parameter.

Solution of The problem:
----------------------------------
Give the necessary permission to the user so that OS user who is running oracle can create file in the specified directory. or put the db_recovery_file_des in the duplicate command

First Scenario:
------------------------------------------
 duplicate target database to 'TARGET_1' from active database
spfile
set db_file_name_convert '/u01/dba/db/data/SOURCE_1','/u02/TARGET_1/db/data/TARGET_1'
set LOG_FILE_NAME_CONVERT '/u01/dba/db/data/SOURCE_1','/u02/TARGET_1/db/data/TARGET_1'
set control_files '/u02/TARGET_1/db/data/TARGET_1/control01.ctl','/u02/TARGET_1/db/fast_recovery_area/TARGET_1/control02.ctl'
set diagnostic_dest '/u02/TARGET_1/db'
set db_recovery_file_dest '/u02/TARGET_1/db/fast_recovery_area'
set audit_file_dest '/u02/TARGET_1/db/admin/TARGET_1/adump'
SET log_archive_dest_1 'location=/u02/TARGET_1/db/arch'
;


Second Scenario:
--------------------------------
In the second scenario user don't have permission on flash recovery area.
You can see flash recovery area location by,
SQL> show parameter db_recovery

# chown -R oracle:dba /u02/TARGET_1/db/fast_recovery_area


Now try to do operation and hopefully it will work.
