Query to find the Views and synonyms that are accessing through db_link

HI all,
Oracle 10g
I need a Query to find the Views and synonyms that are accessing through db_link.
ie.
database A have the db_link to database B through a schema A
now i need to find what are the Synonyms and views that are accessing through db_link either directly or indirectly..

Edited by: Deepak_DBA on Dec 10, 2010 5:38 PM

On the second database (B) use this query to find the SQL which used by the schema A (DB LINK USER). Check the SQL_FULLTEXT column.
select sql_fulltext,sql_id,module,parsing_schema_name,parsing_user_id,first_load_time,loads,users_executing,rows_processed,plsql_exec_time,sorts,fetches,invalidations,parse_calls,cpu_time,elapsed_time,disk_reads,buffer_gets
from V$sqlarea
where parsing_schema_name = 'A' --and to_char(first_load_time,'dd/mm/yyyy') like '%11/08/2007'
order by first_load_time desc;

Query to find the list of users having access to a particular scenario

Hi,
I am learning Hyperion Planning 9.2 x version. I wanted to know the query to find the list of users having access to Plan Iteration - 1 scenarion.
As I am new to Hyperion Essbase and Hyperion Planning, I am assuming these ideas work out to get the desired result.
1) As Hyperion Planning uses Relational DB to store the User Security information, we can query the list of users who is having access to Plan Iteration - 1 Scenario.
I am not sure if this solution works. Please correct me If I am wrong.
2) We can also query from the essbase editor to find out who all having access to this scenario.
If the above is correct, can you please provide me the query.
I am really need of this and I will be happy if any one provide the solution.
Thanks & Regards,
Upendra. Bestha

Hi,
If you are looking for some SQL to retrieve the access rights by member then you can use something like (SQL Server code though can easily be modified for Oracle)
SELECT usr.object_name as Username,mem.object_name as Member,
'Access Rights' = CASE acc.access_mode
WHEN -1 THEN 'None'
WHEN 1 THEN 'Read'
WHEN 2 THEN 'Write'
WHEN 3 THEN 'Write'
ELSE 'Unknown' END,
'Relation' = CASE acc.flags
WHEN 0 THEN 'Member'
WHEN 5 THEN 'Children'
WHEN 6 THEN 'Children (inclusive)'
WHEN 8 THEN 'Descendants'
WHEN 9 THEN 'Descendants (inclusive)'
ELSE 'Unknown' END
FROM
hsp_access_control acc, hsp_object mem, hsp_object usr
WHERE acc.object_id = mem.object_id
AND acc.user_id = usr.object_id
AND mem.object_name = 'Plan Iteration - 1'

How do I find the overall database size?
The biggest portion of a database's size comes from the datafiles. To find out how many megabytes are allocated to ALL datafiles:
select sum(bytes)/1024/1024 "Meg" from dba_data_files;
To get the size of all TEMP files:
select nvl(sum(bytes),0)/1024/1024 "Meg" from dba_temp_files;
To get the size of the on-line redo-logs:
select sum(bytes)/1024/1024 "Meg" from sys.v_$log;
Putting it all together into a single query:
select a.data_size+b.temp_size+c.redo_size "total_size"
from ( select sum(bytes) data_size
from dba_data_files ) a,
( select nvl(sum(bytes),0) temp_size
from dba_temp_files ) b,
( select sum(bytes) redo_size
from sys.v_$log ) c;
Another query ("Free space" reports data files free space):
col "Database Size" format a20
col "Free space" format a20
select round(sum(used.bytes) / 1024 / 1024 ) || ' MB' "Database Size"
, round(free.p / 1024 / 1024) || ' MB' "Free space"
from (select bytes from v$datafile
union all
select bytes from v$tempfile
union all
select bytes from v$log) used
, (select sum(bytes) as p from dba_free_space) free
group by free.p
This is what I use :P From http://www.orafaq.com/wiki/Oracle_database_FAQ#How_do_I_find_the_overall_database_size.3F

Query to find the latest record with respect to the current status

Dear gurus
I have the following data in a table
Customernum
bkcode
reqtdate
Prevstat
currstat
The data will be like this
CustomerNum bkcode reqdate prevstat currstat
5900 1 03-Aug-12 0 1
5900 1 06-Aug-12 1 0
5900 5 22-Jun-12 0 1
If a customer has an issue to solved, a record is added with bkcode , register date and currstat will be 1
If the issue is resolved for the bookingcode,a new record is added, the currentstatus will become 0. and prev stat will show 1. Row no 1 and 2 reflects this case
If this table is queried for finding the unresolved issues. the output should be only the Last row of the above example. since issue with bookingcode 1 has been resolved
I have trying hard to get this thing confused what to use Lead or Max
Kindly guide me

Hi,
one way here:
WITH mytable(CustomerNum, bkcode, reqdate, prevstat, currstat)
AS
   SELECT 5900, 1, TO_DATE('03-Aug-12', 'DD-Mon-YY'), 0, 1 FROM DUAL UNION ALL
   SELECT 5900, 1, TO_DATE('06-Aug-12', 'DD-Mon-YY'), 1, 0 FROM DUAL UNION ALL
   SELECT 5900, 5, TO_DATE('22-Jun-12', 'DD-Mon-YY'), 0, 1 FROM DUAL
SELECT CustomerNum, bkcode, reqdate, prevstat, currstat
FROM (SELECT a.*
             , ROW_NUMBER() OVER (PARTITION BY CustomerNum, bkcode
                                       ORDER BY reqdate DESC) AS rn
          FROM mytable a
WHERE rn=1
   AND currstat=1;
CUSTOMERNUM     BKCODE REQDATE     PREVSTAT   CURRSTAT
       5900          5 22-JUN-12          0          1Regards.

Query to find the Salary table details HRMS 11i

I am looking query to find the persons salary details in Oralce EBS 11i.
I tried the below query bu it didn'ty work.
SELECT papf.employee_number
,papf.full_name
,pj.NAME job
,haou.NAME ORGANIZATION
,ppp.proposed_salary_n salary
FROM per_all_people_f papf
,per_all_assignments_f paaf
,per_jobs pj
,hr_all_organization_units haou
,per_position_definitions ppd
,per_all_positions pap
,per_pay_proposals ppp
WHERE 1 = 1
AND SYSDATE BETWEEN papf.effective_start_date AND papf.effective_end_date
AND papf.current_employee_flag = 'Y'
AND papf.employee_number IS NOT NULL
AND paaf.person_id = papf.person_id
AND SYSDATE BETWEEN paaf.effective_start_date AND paaf.effective_end_date
AND paaf.job_id = pj.job_id
AND paaf.organization_id = haou.organization_id
AND paaf.position_id = pap.position_id
AND pap.position_definition_id = ppd.position_definition_id
AND ppp.pay_proposal_id = (SELECT MAX (pay_proposal_id)
FROM per_pay_proposals
WHERE assignment_id = paaf.assignment_id)
In our case all the below tables have 0 records..
select count(*) from PER_PAY_PROPOSALS ;
COUNT(*)
         0
select count(*) from pay_element_entry_values_f;
COUNT(*)
         0
select count(*) from PAY_ELEMENT_ENTRY_VALUES_F;
COUNT(*)
         0
select count(*) from PAY_ELEMENT_ENTRIES_F;
COUNT(*)
         0

Hi,
Your results clearly states that there is no salary data which is been captured as well as there are no element entries which are assigned to any assignment.
Please do the below which will insert records in salary as well as element entries table:
1. Add a salary proposal to any active employee (People Enter and Maination --> Search for any employee --> Assignment --> Salary) - This will insert a record in PER_PAY_PROPOSALS table
2. Add an element entry to any active assignment (People Enter and Maination --> Search for any employee --> Assignment --> Entries) - This will insert a record in PAY_ELEMENT_ENTRIES_F and PAY_ELEMENT_ENTRY_VALUES_F table
Hope this clarifies.
Thanks,
Sanjay
