In one of my application oracle net connection is taking 30 to 40 ms(tnsping servicename),but in actual connection is always taking more than 45 ms, and my application requirement is below than 10 to 20 ms.
And can i use any other connection method like hostname, ezconnect etc.
I am working with a new client and am still waiting on access to systems so I'm a bit hampered in looking at details of the database and environment. The database is OLTP and typical response time for returning result sets is under 2 seconds, often less than 1 second.
A simple SELECT on a few columns of v$session_longops (no subqueries, group by, having, etc) ran for more than 5 minutes.
The below query is taking more than 5minutes to return the data for any criteria.The big tables are
SECURITY_POSITION_SUMMARY -- 60Million
WEB_TEAM_X_ACCOUNT_BM -- 26Million
and the rest of those are small tables..All the indexes are in place and I have tried with few hints but this query is slow.

Apex 3.2. I have a page with a button. Once the user clicks the button a call is made to a procedure in a package.This procedure acesses a couple more procedures and functions, inorder to import data from one table to another. If the procedure takes more than 5 minutes to complete, the user receives an error message.This is actually the error message the user should get if he tries to do an import while another user’s import is running. Is it possible that if the called procedure doesn’t return in under 5 minutes the page is reloaded and the procedure called again resulting in the above error message.

i have a Windows Forms .Net 2.0 App which defines AppDomain.CurrentDomain.UnhandledException handler.When an app thread throws an exception this exception is caught or handled by this method.
The problem is that if i define an OracleConnection, open and close it and then the thread throws the exception this is not handled and app finishes...
Why i can't handled this threads exceptions if i use OracleConnection?
Here is the simple app code example:
program.cs
[STAThread]
static void Main()
{
AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException;
Application.ThreadException += Application_ThreadException;
Application.SetUnhandledExceptionMode(UnhandledExceptionMode.ThrowException);

i'm trying to install a development-environment. The production- and testing-environmens are working, but i have problems with the development.
I installed Oracle 10g XE 10.2.0.1.0 and Apex 4.1.1.00.23 on my Oracle VM Virtual Box (Windows 7 Professional 64 bit).
127.0.0.1:8080/apex works from the Virtual Box.
192.168.11.42:8080/apex (the IP in my network) and 192.168.11.42:8080 work either from the Virtual Box.
But it doesn't work from other clients in my network. So far i tried exec dbms_xdb.setlistenerlocalaccess(false).
i want one query which return minute between two times which is in this format: 12:00:00 and 06:00:00
so in this it should return 360 minutes.
is there a prebuilt function that will round say the time of a sysdate up or down 5 mins? so i entered 5:32pm i would want it to round it down to 5:30pm
View 1 Replies View RelatedI have two columns which I need to add together then devide by 60 in order to display that time in minutes. the problem I am facing is that at times I get numbers above 60 and my client doesn't want to see numbers above 60.
i.e (col1 + col 2)/60 = 34.87
what I need to do is make sure that when the number reaches 60 it moves on to 35.
I need below proc like...
procedure p1
(
i_time_min number -- minutes to be substracted from timestamp
)
is
v_end_timeinstamp timestamp(6);
begin
[code]....
The problem with above procedure is passing parameter is in minutes and i need to substract the same from sys_extract_utc(current_timestamp) and store result in v_end_timeinstamp in timestamp format only... substracting directly will reduce the days and not the minutes.
How to count records per every 3 minutes ? we don't want SPs to get answer. Instead of we want single query to get this output.
The sample data has been enclosed with it.
I have a date in_sdate as In parameter defaulted to sysdate. Basing on this in_Sdate I calculate my start and end dates as:
v_sdate TRUNC (in_sdate, 'MI') - 15 / 1440 ;
v_edate := TRUNC (in_sdate, 'MI');
My procedure is run for every 15 minutes. Now suppose if I am running for old dat, then I should get the difference of dates by taking
v_old_Date := v_edate - in_Sdate;
Divide this by 15 , round that value and loop to run the procedure for that n times. My doubt is when I am saying
v_old_date := v_edate - in_sdate ; I am getting expression is of wrong type. How can I take the difference of the dates and get the minutes from that ?

View 12 Replies View RelatedI have a Windows 2003 VirtualBox instance, to which I assigned 3 out of 4 cores my laptop has. This is a demonstration environment for an Oracle vertical product. I got it from my colleagues. The OS boots without starting the DB services - I did this deliberatley while trying to figure out what is happening.
About 2 and half to 3 and a half minutes after the service is started the oracle.exe "latches onto a core and does not let go" (as best as I can describe what I see). With 3 cores I see 33%-34% cprocessor use in the task manager with oracle.exe doing all the using. Nothing else is started. There is no process of which I am aware which actually uses the DB. I only start the TNS listener and the database service.
Once I start it, the demonstration software uses the database extensively for complex queries. With one of the 3 cores 100% used by the oracle.exe I am running short on CPU at times, which makes the demonstratin seem slaggish, and queries take longer than is really acceptable (not surprising seeing oracle.exe is very busy doing I know not what).
i want to convert minutes that is 90 want to convert it in hours and minute that format should come in 01:30 format.
can i get in this format?

I currently have a problem where I have two date fields with time stamps. The only bit i am currently interested in in these fields is the time factor. When i display them in their field they have a format of HH24:MI .
I have a start time and end time as well as a duration and duration type. What I am trying to do is the following: when the user inputs the start time, along with the duration say 1 for example and the duration type of say HRS for example I would like to have the end_datetime default to 1 HR from the current start time. This is the code I use on a when validate item trigger to acheive this:
case :blk.duration_type
when 'HRS' then
:blk.end_datetime := :blk.start_datetime + ((1/24)* :blk.duration);
when 'MINS' then
:blk.end_datetime := :blk.start_datetime + ((1/24/60)* :blk.duration);
However, every time it triggers the value put into end_datetime is 0:00 is it something to do with the datatypes im using .
I have a field " Tran_date " with datatype Date . It contains date as well as time . How can I get the time . I tried with it as below :
SELECT TO_CHAR(TRAN_DATE,'DD-MON-YYYY HH24:MI:SS') FROM ABC
WHERE COMP=1 AND
BRANCH=1 AND
LOC_CODE='12' AND
TRAN_DATE='12-JAN-2012' ;
VALUE IS COMING LIKE THIS :
12-JAN-2012 00:00:00
ALTHOUGH THERE IS TIME . Its not zero .
I have a query to add two numbers and get results in hours:minutes format.Example I want to add 12.20 and 6.15 and get result in hours and minutes like 18.35 (hours & minutes).if minutes that is after precision exceed more than 60 it should treat as 1 hour.like i want to add
12.35 (number 1) before precision its hour and after its minutes
06.25 (number 2)
04.25 (number 3)
-----
23.25 (23 hours and 25 minutes)

I want to find the hours and minutes between two char field data type.Example I have two char columns one is "start_time" and another one is "end_time".The start time and end time is the machine reading of CNC MACHINE in manufacturing.I want to develope the package to capture the actual machine running time.But I have the start and end time reading in character field.The machine reading format is hour:minutes:seconds only.It will looks like 1234:45:23(the machine ran 1234 hours and 45 minutes and 23 seconds).See the below table to understand my requirements.
start_time end_time result in hours & minutes
---------- -------- -------------------------
345 347 2 hrs
347 350 3 hrs
350 357.20 7 hrs and 20 minutes
If I subtract end_time - start_time I will get the result in char type only not in hours and minutes format.Another example
start_time end_time result in hours & minutes
---------- -------- -------------------------
357.21 360.40 3.19(If subtract end_time - start_time)
