In 12c and later version of the oracle database I can use this built-in function to get the program name:

sys_context('USERENV','CLIENT_PROGRAM_NAME')

In 11g what is the similar parameters or function that I can use? Please help.

Thank you,
Warren

Create a procedure from an authorized account and grant the execute privilege to the unprivileged user:

Code: [Select all] [Show/ hide]

SQL> Create or replace function my_program return varchar2
  2  is
  3    prog v$session.program%type;
  4  begin
  5    select program into prog from v$session where sid=(select sid from v$mystat where rownum=1);
  6    return prog;
  7  end;
  8  /

Function created.

SQL> grant execute on my_program to scott;

Grant succeeded.

SQL> conn scott/TIGER
Connected.
SCOTT> select michel.my_program from dual;
MY_PROGRAM
---------------------------------------------
sqlplus.exe

This may or may not be related to your problem. V$mystat is a synonym for the v_$mystat table.
Privileges must be granted on the table, not the synonym. Please see the example below that demonstrates that.

-- reproduction of your error:

Code: [Select all] [Show/ hide]

SYS@orcl_12.1.0.2.0> connect test/test
Connected.
TEST@orcl_12.1.0.2.0> select program
  2  from   v$session
  3  where   sid = (select sid from v$mystat where rownum=1)
  4  /
where   sid = (select sid from v$mystat where rownum=1)
                               *
ERROR at line 3:
ORA-00942: table or view does not exist

-- unable to grant select on v$mystat:

Code: [Select all] [Show/ hide]

TEST@orcl_12.1.0.2.0> connect sys as sysdba
Connected.
SYS@orcl_12.1.0.2.0> grant select on v$mystat to test
  2  /
grant select on v$mystat to test
                *
ERROR at line 1:
ORA-02030: can only select from fixed tables/views

-- identification of v$mystat as synonym and identification of v_$mystat as underlying table:

Code: [Select all] [Show/ hide]

SYS@orcl_12.1.0.2.0> select object_type
  2  from   dba_objects
  3  where  object_name = 'V$MYSTAT'
  4  /

OBJECT_TYPE
-----------------------
SYNONYM

1 row selected.

SYS@orcl_12.1.0.2.0> select table_name
  2  from   dba_synonyms
  3  where  synonym_name = 'V$MYSTAT'
  4  /

TABLE_NAME
--------------------------------------------------------------------------------
V_$MYSTAT

1 row selected.

-- granting of select on underlying table v_$mystat:

Code: [Select all] [Show/ hide]

SYS@orcl_12.1.0.2.0> grant select on v_$mystat to test
  2  /

Grant succeeded.

-- original select statement now runs without error:

Code: [Select all] [Show/ hide]

SYS@orcl_12.1.0.2.0> connect test/test
Connected.
TEST@orcl_12.1.0.2.0> select program
  2  from   v$session
  3  where   sid = (select sid from v$mystat where rownum=1)
  4  /

PROGRAM
----------------------------------------------------------------

1 row selected.

The problem is not with V$MYSTAT (or SYS.V_$MYSTAT) which is granted SELECT to PUBLIC (default settings in 11g) but with V$SESSION:

Code: [Select all] [Show/ hide]

SQL> select grantee from dba_tab_privs where owner='SYS' and table_name='V_$MYSTAT' and privilege='SELECT' order by 1;
GRANTEE
------------------------------
APEX_030200
PLUSTRACE
PUBLIC
SELECT_CATALOG_ROLE

4 rows selected.

SQL> select grantee from dba_tab_privs where owner='SYS' and table_name='V_$SESSION' and privilege='SELECT' order by 1;
GRANTEE
------------------------------
APEX_030200
APPQOSSYS
CTXSYS
ORACLE_OCM
PERFSTAT
SELECT_CATALOG_ROLE

6 rows selected.

SQL> @v

Oracle version: 11.2.0.4.181016 EE - JVM v1.6.0_43 - timezone files v11

We can use own context:

Code: [Select all] [Show/ hide]

create or replace
  context ctx
    using ctx_pkg
/
create or replace
  package ctx_pkg
    is
      procedure set_program;
end;
/
create or replace
  package body ctx_pkg
    is
      procedure set_program
        is
            v_program varchar2(64);
        begin
            select  program
              into  v_program
              from  v$session
              where sid = sys_context('userenv','sid');
            dbms_session.set_context('ctx','program',v_program);
      end;
end;
/
create or replace
  trigger after_login_trg
  after logon
  on database
  begin
      ctx_pkg.set_program;
end;
/

Now:

Code: [Select all] [Show/ hide]

SQL> connect u1/u1@orcl11
Connected.
SQL> select banner from v$version;
