Setting the utl_file_dir parameter in 10g

Question

I want to set the 'utl_file_dir' parameter. From the internet I found that I can do it from OEM (the web-based one) by choose 'All initialisation Parameters...SPFile Tab...' (Refer to http://otn.oracle.com/obe/obe10gdb/bidw/blast/blast.htm#t0c).
However will this be temporary until the instance restarts? Also, will the change take effect after the restart of instance?

Answer 1

There is another way you can specifiy the utl_file_dir in 10g without bouncing...
Specify the UTL_FILE_DIR in 10g :-
Two way you can specify the UTL_FILE_DIR:-
     a) Using Spfile (Database Bouncing is require)
     b) Using DIRECTORY (Database Bouncing is not required)
a) Using Spfile (Database Bouncing is require)
     i) Login as sys user:-     
     SQL> conn sys@oratest as sysdba
     Enter password:
     Connected.
     SQL>
     SQL> show parameters utl
     NAME TYPE VALUE
     utl_file_dir string
     SQL>
     SQL>
     SQL>
     SQL> alter system set utl_file_dir='/u01/preproc/output', '/u01/app/oracle/admin/ARGOS/output' scope=SPFILE;
     System altered.
     SQL> show parameters utl
     NAME TYPE VALUE
     utl_file_dir string
     SQL>
     SQL> SHUTDOWN IMMEDIATE
     ORACLE instance shut down.
     SQL>
     SQL> STARTUP
     ORACLE instance started.

b) Using DIRECTORY (Database Bouncing is not required)
     SQL> connect system/xxxx@oratest
     SQL> SELECT d.owner, t.privilege, d.directory_name
     FROM user_tab_privs t, all_directories d

     i. Create a directory for UTL_FILE_DIR FOR PL/SQL package outputs.
     $ mkdir -p /u01/preproc/output
     $ chown -R oracle:oinstall /u01/preproc/output
     $ chmod -R 755 /u01/preproc/output
     SQL> connect system/xxxx@oratest
     SQL> CREATE OR REPLACE DIRECTORY UTL_FILE_DIR as '/u01/preproc/output';
     Directory created.
     GRANT 'read,write' ACCESS to the Specific User.
     SQL> GRANT read,write ON DIRECTORY UTL_FILE_DIR to PREPROC;
     Grant succeeded.
     SQL> GRANT read,write ON DIRECTORY UTL_FILE_DIR to JOB_TICKET_SCHEMA;
     Grant succeeded.
     SQL> GRANT read,write ON DIRECTORY UTL_FILE_DIR to DISE;
     Grant succeeded.
     SQL> GRANT read,write ON DIRECTORY UTL_FILE_DIR to PLAYPEN
     Grant succeeded.
     REVOKE 'read,write' ACCESS from the Specific User.
     SQL> REVOKE read,write ON DIRECTORY UTL_FILE_DIR from PLAYPEN;
     Revoke succeeded.
