I am trying to get the content of a trace file generated for me.
Because I don't have privileges to log on the server and copy the trace file for me directly with some os user, I am doing the following:
1. I alter my session trace identifier to easier identify the trace file
ALTER SESSION SET TRACEFILE_IDENTIFIER = 'Func01';2. I invoke DBMS_MONITOR
3. I run the procedure I want to monitor.
4. I disable the monitoring by calling DBMS_MONITOR
5. At this point I run the following query to identify my trace file:
select u_dump.value || '/' || instance.value || '_ora_' || v$process.spid || nvl2(v$process.traceid, '_' || v$process.traceid, null ) || '.trc'"Trace File"
from V$PARAMETER u_dump
cross join V$PARAMETER instance
cross join V$PROCESS
join V$SESSION on v$process.addr = V$SESSION.paddr
where 1=1
   and u_dump.name = 'user_dump_dest'
   and instance.name = 'instance_name'
   and V$SESSION.audsid=sys_context('userenv','sessionid');It gives me: /ORACLE/MYDB/trace/MYDB_ora_3616822_Func01.trc
I have created directory in advanced on the path where the traces are stored:
CREATE OR REPLACE DIRECTORY trace_dir AS '/ORACLE/MYDB/trace/';
SELECT * FROM dba_directories WHERE directory_name = 'TRACE_DIR';
Output:
OWNER DIRECTORY_NAME DIRECTORY_PATH
SYS     TRACE_DIR      /ORACLE/MYDB/trace/I don't have rights to grant read, write on TRACE_DIR to my user, as I am not logged with SYS.
I created a table to store in it the lines from the trace file:
CREATE TABLE tmp_traces_tab
  callnum NUMBER,
  line NUMBER,
  fileline CLOB
);Then I run the following PL/SQL block to retrieve the content of the trace and store it in the table T:
DECLARE
  l_file            UTL_FILE.file_type;
  l_location     VARCHAR2 (100) := 'TRACE_DIR';
  l_filename    VARCHAR2 (255) := 'MYDB_ora_3616822_Func01.trc';
  l_text           VARCHAR2 (32767);
  l_line           NUMBER := 1;
  l_call           NUMBER := 1;
BEGIN
  -- Open file.
  l_file := UTL_FILE.fopen (l_location, l_filename, 'r', 32767);
  -- Read and output first line.
  UTL_FILE.get_line (l_file, l_text, 32767);
  INSERT INTO tmp_traces_tab (callnum, line, fileline) VALUES (l_call, l_line, l_text);
  l_line := l_line + 1;
  BEGIN
    LOOP
      UTL_FILE.get_line (l_file, l_text, 32767);
       INSERT INTO tmp_traces_tab (callnum, line, fileline) VALUES (l_call, l_line, l_text);
       l_line := l_line + 1;
    END LOOP;
  EXCEPTION
    WHEN NO_DATA_FOUND THEN
      NULL;
  END;
  INSERT INTO tmp_traces_tab (callnum, line, fileline) VALUES (l_call, l_line, l_text);
  l_line := l_line + 1;
  UTL_FILE.fclose (l_file);
END;
/And when I run the code I get the error: ORA-29283 invalid file operation.
Is it possible to a role my user to be able to get the content of the trace files in the directory TRACE_DIR without having explicit READ , WRITE privileges on it?
My user currently has these roles:
select * from dba_role_privs where grantee = USER;
Output:
U1     OPR_ROLE_LOSS_SNAPSHOT_READER     YES     YES
U1     RESOURCE     NO     YES
U1     CONNECT     NO     YES
U1     DBA     NO     YES
U1     OPR_ROLE_SUPPORT_USER     YES     YESI know that on another db with different user I hit no errors when doing completely the same (of course the program unit I monitor is different).
That other user with which I have NO issues has these roles:
select * from dba_role_privs where grantee = USER;
Output:
U2    DBA    NO    YES
U2    EXEC_SYS_PACKAGES_ROLE    NO    YES
U2    EXECUTE_CATALOG_ROLE    NO    YES
U2    CONNECT    NO    YES

Thanks for posting version alongwith other details.
TO my knowledge, No you cannot.
Privileges acquired via a Role are not valid in PL/SQL. You need to have explicit privileges.
