PL/SQL :: OrdImage Rotate Time Consuming
Feb 13, 2013
I am using an OrdImage type to allow me to rotate a photo and I understand the larger the photo the more time it will take to rotate. However I was wondering if there was a way I could perhaps speed up the process? Currently a photo of 1meg takes approx 27 seconds to rotate, for one about 400k it seems o take about 7 seconds. To me these seem like quite long periods of time for the rotation, though maybe thats how long they take?
I am using oracle 10g and the process I am using for the rotation is: source_ord_image.process('rotate "90"');

Share a query for inactive sessions consuming memory? I have found many inactive sessions with the following query and would like to join this information with memory usage as well.
select username, machine, program, to_char(LOGON_TIME, 'hh24:mi:ss DD-MM-YYYY'), LAST_CALL_ET/60, status from gv$session where status='INACTIVE';

I read and tried a lot, but I can't consume a UTF-8-Webservice correct in a 11gR2-DB: German "Umlaute" like ü are displayed/written as ü.
The service sends all correct. (tested with soap-ui 4.5.1)
The DB-NLS-Parameters are:
SQL> select * from NLS_DATABASE_PARAMETERS;
PARAMETER VALUE
------------------------------ --------------------------
NLS_LANGUAGE GERMAN
NLS_TERRITORY GERMANY
[code]...
I consume Service with that skript:
DECLARE
l_http_request UTL_HTTP.req;
l_http_response UTL_HTTP.resp;
l_buffer_size NUMBER (10) := 512;
l_line_size NUMBER (10) := 50;
l_lines_count NUMBER (10) := 20;
[code]....
What can I do, to get the response correct in NLS_CHARACTERSET WE8MSWIN1252.I think, it must be possible to convert the response, but I didn't found the correct solution.And I don't understand, why the body_charset is ever "ISO-8859-1" (commented in procedure). Settings utl_http.body_charset is without effect.

The table has 64 partition.. When i count the table(select count(*) from table), i see close to 22 million records.

It is supposed to take 75 GB. But this table is consuming 135 GB now. It is occupying 8 GB per day.

How can I find out the particular oracle session which was consuming high memory in the past?
I can't get the data in v$sessstat
Unable to get the information in AWR
dba_hist_active_session_history do not have field which indicate memory related information
Shall I concetrate on EVENT in dba_hist_active_session_history which continuosly had sort, direct path read
Or
Locate sql_id from dba_hist_sqlstat with high SORTS_DELTA for snapshots belonging to problematic time period and then using the sql_id query dba_hist_active_session_history
which approach I shall take to find out the session which consumed most memory in the past?

When I try to extract the date tag value from XML data, the time stored in 20120602153021 format i.e., YYYYMMDD24HHMISS format. The following statement extracts only date as 02-JUN-12 however do not extract the time part.
If I try the same in SQLplus with to_date it works however fails in PL/SQL.
XML data:
<?xml version="1.0"?>
<RECORD>
<REGTIMESTAMP>20120601130010</REGTIMESTAMP>

PL/SQL Extract:
CURSOR c_xml_record
IS
SELECT extract(value(d), '//ACTIVATIONTS/text()').getStringVal() AS REGTIMESTAMP,
FROM t_xml_data x,

I have one inline view query which shows exec\ fetch : 2 sec\ 19 sec It gives 500 rows as final out put, when i give rownum<100 it shows exec\ fetch : 1 sec\ 000 sec, and i cannot use this rownum< 100 alternative as this is inline subquery of big query.
What does this exec and Fetch time is?
How to improve fetch time, (esp with sub-query) ?

I have a table which stores apointment start times and appointment end times. For the sake of this thread I will call them appt.start_time and appt.end_time. I then have a check in time and a check out time for the customer. The only thing is they ONLY way to distinguish between a check in time and a check out time is which one has the earlier time and which one has the later time. Obviously the earlier time will be the check and the later time will be the check out.
This is fine, however sometimes they may forget to check a person in or out and I need to determine whether the time should be insert into the check_in column or the check_out column. To do this I was thinking of comparing the time with the appointment start and end time and if it was closer to the appointment start time put it into the check_in column and if its closer to the appointment end time put it into the check_out column. But I was wondering how I would go about doing this.
The time I will want to compare against the appointment start and end time I will store in a variable called v_time and have this as part of my query, im just unsure of what way to write the query so as to check if the time is closer to the start or end time.

. I have this query:
select asl1.agentsessionid, asl1.endtime, asl2.starttime, 127 as agentstatus
from
(
select asl1.agentsessionid as sessionid1, min(asl2.agentsessionid) as sessionid2
from cti.agentsessionlog asl1
[code]...
As you can see from my where statement I want to compare the endtime with the startime. This query returns zero results. Is there a way to write the where statement different so I can have results?

I have an application in which time is show as . But, in the table in Oracle it is showing as 13:00. The application is taking the time from OS. OS time is 18:30 IST. Time in SYSDATE is also showing as 18:30. DBTIMEZONE is '+5:30'. what is the problem in Database and how that can be rectified to show the time as same as OS time.

We have a Oracle 10g database with RAC and Dataguard. When we look at the AWR report, the wait time shown by Oracle for this database is very high.
Service Time : 15.36%
Wait Time : 84.64%
This would imply Oracle is waiting for resources 85% of the time and only processing SQL queries during 15% of its non-idle time. However when we check the OS (RHEL), the iowait is only about 10% and the CPU is 80% idle. This means that that processing horsepower is available.
As such, the results between the OS and Oracle database (AWR report) seems contradictory. OS says we have CPU/IO capacity, however Oracle says we don't.

I'm using Oracle 11g and I have a bunch of indexes and I want to check if they are being used. I just ran my workloads and now I want to see when each one was last used so I can see if it was during my timeframe or not.
After I ran my test, I found the below, but since I did not enable this, plus I have many indexes.
--Monitor an index to see if it's used
alter index SAMPLE_INDEX monitoring usage;
select * from v$object_usage where index_name = 'SAMPLE_INDEX';
alter index SAMPLE_INDEX nomonitoring usage;

I have an issue while converting Date. I need to compare the Time Captured while comparing Dates,
find the following scenario,
SELECT TO_CHAR(ffdh.last_update_datetime,'DD-MON-RR-HH24:MI:SS') TIME_STAMP ,
ffdh.last_update_datetime,
to_date(ffdh.last_update_datetime,'DD-MON-RR-HH24:MI:SS') DATES ,
ffdh.fiscal_doc_id INVOICE_ID
[Code]....
Note That ffdh.last_update_datetime is DATE, and the Parameter for the value '17-JUN-10-01:30:17' is VARCHAR2
I suspect when I am doing to_date above both are converting only to Date and not having Time.
I checked the NLS_DATE_FORMAT as following,
SQL> show parameter nls_date_format
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
nls_date_format string DD-MON-RR
Do I need to Change the NLS_DATE_FORMAT ?

Checkout the following code
CREATE TABLE CHK(dt_request_datetime DATE);
INSERT INTO CHK VALUES(TO_DATE('25-JUN-10 04.12.57 AM',
'DD-MON-YY HH:MI:SS AM'));
COMMIT;
[Code].....
TZ_OFFS TZ_OFFS GMT_TIME
------- -------
-04:00 +00:00 25-JUN-10 04.12.57.000000000 AM
EST_TIME
-----------
25-JUN-10 12.12.57.000000000 AM EST
9 am
----
25-JUN-10 09.00.00.000000000 AM EST
8 pm
-----
25-JUN-10 08.00.00.000000000 PM EST
OUTPUT
---------
30-JUN-11
My doubt here is that even though dt_request_datetime is between 9 am in EST timezone and 8 pm in EST timezone the query output is not according to that.

We are using Oracle 10g on Linux. Followings are some contents from the AWR report:
Elapsed: 60.26 (mins)
DB Time: 437.27 (mins)Here why the DBTime is greater than Elapsed Time. Is it due to the fact that this is the total time spent in user calls by multiple sessions i.e. ( some sessions were on CPU, some were in IDLE state waiting for I/O)
The below statistics show that CPU was used only for 5,363 seconds. We have 8 CPU grid, so total CPU time is 60.26* 8= 482.08 Min. I want to know where does the remaining time was spent. Also there is 20.4% of Total Call Time. How does it is calculated.
CPU time 5,363 20.4. The below statistics for reference:
BUSY_TIME 1,218,675
IDLE_TIME 1,675,112
[code].....
