Timer in the database

Hello, I have a question about the timer in the database.
I have a job that has a priority of 1. That job needs to run from time to time.( that is to run once and then sleep for a while.) The sleeping time is provided by another job. I am using DBMS_LOCK.sleep().
When the database is almost idle, if I set the sleeping time is 2 seconds, then it is accurate. But when the database has some workload (that means there are other jobs running), and the cpu util is not very high (around 70%). If I set the sleeping time as 2 sec, I found the actual sleeping time is almost 3 sec.
Are there any better ways to improve the accuracy? How about I set the timer on another idle machine, and that machine sends a request to the database and then the database response that request?
Great thanks.

Hi,
I don't think that the actual time taken by dbms_lock.sleep should vary that much with the load on the database. You can use plsql profiling or tracing to see where the time is really being taken up.
How are you using another job to provide the sleep time to the first job ? If you are using a table maybe you might be able to get a better response using dbms_pipe instead.
Depending on where your bottleneck is using another idle machine to do the scheduling may provide a better worst response time. But the average response time may be worse because of network latency.
Hope this helps,
Ravi.

Changing the OS local time while the database is Up and Running

Hi,
Will there be any bad effect if I change the OS local time of my servers while the database and application is up and running?
Why do I need to do this? because the database is RAC configured and I want to avoid "brain-split" because of discrepancies
in the local time of DB Servers.
NTP is not yet implemented so I am to adjust the time manually for each servers.
BTW, I am using database 10gR2 (10.2.0.4) and EBS application (11.5.10.2). My nodes are running in Linux 4, 2.6.9-42ELsmp x86_64.
Regards,
Jay A

But my very concern right now is if there will be negative effect on the data or timestamp in the datafiles of the database
because I change the local time of the server while the database is running.Change time, that make time in database is changed. and you are changing time at milliseconds. you won't see affect.
we should worry different time between servers more than time changing
you can use ntpdate to query time different from server before.
# ntpdate -q ntp.server.org

How to insert the sysdate time into the database

hi all,
when i execute the following query,
insert into table_name
(date_field)
values
(to_date(sysdate, 'yyyy/mm/dd hh24:mi:ss'));
The value is inserted as 08-02-12 12:00:00. In this query, it always stores the default time as 12 a.m.
But i need to insert the original system time not the default one.
please help me how to rectify it.

I do not understand as to why you are using the to_date function on sysdate since sysdate is already in date format.
If date_field is of the data type date, then the following dml should work.
insert into table_name(date_field) values (sysdate);
In case date_field is a varchar2 field and you want to store the date and time in a string format, then the following statement should work.
insert into table_name (date_field)
values (to_char(sysdate, 'yyyy/mm/dd hh24:mi:ss'));

How can I use the database default time rather than Java supplied time

I've searched over and over and nobody seems to have this issue so maybe its just me!
When inserting a record I would like the a create_date column to automatically use the database time rather than a supplied time via JPA. That was all times a relative to the database which makes sense.
The trouble is I cant figure out how to do this in a sensible manor.
If I specify an column like :
     @Temporal(TemporalType.TIMESTAMP)
     @Column(name = "CREATE_DATE")
     private Date createDate;
and IDL
CREATE_DATE TIMESTAMP WITH TIME ZONE DEFAULT CURRENT_DATE NOT NULL
If I leave createDate null I get an exception. If modify the column to allow Nullable then column is set as Null.
If I leave the column out of the entity bean and then and create a row then the database current time is inserted. The trouble then is that if I want to read the date I'm going to have to create a copy of the bean but with the CREATE_DATE in it, and this doesn't make sense.

I should also mention that TopLink has always supported the ability to retrieve the current time from the database for use in optimistic locking. The TimestampLockingPolicy offers the ability to configure the next value being retrieved from the database instead of using the local time from the JVM. Our extended optimistic locking configuration does not currently support setting this option but it could be done using a descriptor customizer which can be configured in your persistence unit properties.
Using optimistic locking may be a good solution for the last modified date since it will also ensure that you do not corrupt the database if someone else has incremented this value since your last read.

The paths won't agree on the two OSs so a simple XML import isn't likely to work.
See Sync iPod/iPad/iPhone with two computers and, if needed, Make a split library portable. The techniques in the first link will work when moving the library between Windows and OS X as long as the library is "portable", but iTunes takes quite some time checking the database when the library is opened under a different OS.

How do i store and fetch image from the Database(Access)

i am facing one problem in inserting the image into the database.the steps i followed as
1)i have created one database(access) as "Image" and into that one table as "Image" and field as "image"
type of the field is ole object.
2)i have inserted one image into the image field through "database.vi"
3)now i am trying to get the image from the database by "Fetching Example.vi"
4)it will succesfully retrieve the image from that field .
5)but when i close the both programs and reopen those that time i am unable to get retrieve the image.

I would like to suggest different approach for saving the images in the database.
I was working on Medical Imaging Company. The way we save the images in real-time was by writing the name and path of the images to database.
The images themselves where saved directly to disk.
I don�t think that access is very good in taking care of GBytes of data.
It happens some time that the database gets damage. If you have the images separately you can create fix procedure. (We had one).

Problem while inserting Date/Time in Oracle Database

Hai,
i want to insert the date and time in a date column. here, i am using java.sql.Date and java.sql.Time to assign the date in Prepared Statement.
PreparedStatement psmt=con.prepareStatement("insert into test(ex_date) values(?)");
java.util.Calendar c=Calendar.getInstance();
c.set(2002,2,21,10,10,00);
java.sql.Date d=new Date(c.getTime().getTime());
java.sql.Time t=new Time(c.getTime().getTime());
psmt.clearParameters();
psmt.setDate(1,d);
psmt.setDate(1,t);
psmt.executeUpdate();
Above program is inserted the Date and time in the database as the following "1900/2/21 10:10 AM"
but i am giving the year as 2002. it inserted the year as 1900. what is the problem with the code?
please let me know
Thanks in advance.

Hai Franco,
i put the wrong code. Here, is the Original Code.

psmt.clearParameters();
psmt.setDate(1,d);
psmt.setTime(1,t); // Last time i put psmt.setDate(1,t);
psmt.executeUpdate();
and, the getTimeInMillis() method is a protected method in java.util.Calendar class. how can we use it
please give me some other idea to insert the date and time in oracle database.
Thanks in advance

I have created a database in oracle9i by following manual steps. Every thing was created successfully and am able to start the database and shutdown also.
but the problem is while giving the startup command it takes more time to start the database and the same during the shutdown. So anyone help me..
the follwing are the pfile specifications:

Secure Store Service Application takes a lot of time and does not create the database

Hi everybody,
I was trying to configure sharepoint performance point and I was following the instruction. After I created the performance point services application I tried to creat the secure store service application. When I do this, the progress window stays open forever
even after 2 hours. If I close the window, I will see that the secure store service and proxy app is created and the application pool also is created in IIS but the database is not and the application service is stopped. even when I want to delete it, it's
the same story and the progress window stays until I close it manually. Nothing has been logged in the event viewer because it doesn't throw any exceptions.
I don't think that I have permission issues on the database server side because I have created the performance point service app and the database is there. I have used the same credentials to crete the secure store.
I have restarted the secure store service and IIS for many times and even the server itself.
I'm wondering if anybody has had this issue because I couldn't find anything on the web.
Thanks,
Edwin

Hello
I have a VeriStand-Project (VSP) created with my Laptop-Host (LTH) which works with my PXI, while
deploying it from my LTH. Then I have installed the whole NI enviroment for PXI and VeriStand use on a
industrial PC (iPC). I have tried to deploy my VSP from the iPC to the PXI but the following error

The software versions of the NI products (MAX/My System/Software) between my LTH and the iPC are
almost the same. The only differences are:
1. LabView Run-Time 2009 SP1 (64-bit); is installed on LTH but missing on iPC. The iPC has a 32-bit system.
2. LabView Run-Time 2012 f3; is installed on LTH but missing on iPC.
3. NI-DAQmx ADE Support 9.3.5; something strage on the LTH, because normally I am using NI-DAQmx 9.5.5 and all other DAQmx products on my LTH are 9.5.5. That means NI-DAQmx Device Driver 9.5.5 and NI-DAQmx Configuration 9.5.5.. On the iPC side all three products are 9.5.5.. That means NI-DAQmx ADE Support 9.5.5, NI-DAQmx Device Driver 9.5.5 and NI-DAQmx Configuration 9.5.5..
4. Traditional NI-DAQ 7.4.4; The iPC has this SW installed. On the LTH this SW is missing.
In order to fix this problem I have formatted my PXI and I have installed the following SW from the iPC:
1. LabVIEW Real-Time 11.0.1
2. NI-488.2 RT 3.0.0
3. NI_CAN 2.7.3
Unfortunately the above stated problem still arose.
What can I do to fix this problem?
I found a hint on http://www.labviewforum.de/Thread-XNET-CAN-die-ersten-Gehversuche.
There it is written to deploy the dbc file againt.
If this is a good hint, so how do I deploy a dbc file?
I would feel very pleased if somebody could help me! :-)
Best regards

Hi Lukas,
I think the problem is caused by differenet drivers for the CAN communication.
NI provides two driver for CAN: NI-CAN and NI-XNET.
NI-CAN is the outdated driver which is not longer used by new hardware. NI replaced the NI-CAN driver with NI-XNET some years ago, which supports CAN, LIN and the FLEXRAY communication protocol.
You wrote:

NI CAN is the outdated driver. I think that you should try to install NI-XNET instead of NI-CAN on your PXI-System, to get rid of the error message.

Return value from database function taking a lot more time than the query

Hi guys,
I have a Query that does a call to a database function. The function takes in a few parameters and returns a Date. Now, the query within the function takes barely .05 seconds. However, doing a select get_join_dates from dual is taking almost 6 seconds for each call.
Here is the Query:
select s.student_id, s.student_name, s.organization_code
from   student s
where s.student_id = :p_student_id
and    s.student_enrollment_date = get_join_dates( :p_year,
                                                   :p_month,
                                                   :p_student_id,
                                                   s.organization_code );And here is the database function. The select inside this function barely takes 0.05 seconds per call. This function gets called 3 times in my case as there are 3 records in the org_body table for this student.
create or replace function
get_join_dates( p_yyyy in org_body.fiscal_yyyy%type,
                       p_month in org_body.fiscal_mm%type,
                       p_student_id in student.student_id%type,
                       p_organization_code in org_body.organization_code%type) return date as
    t_enrollment_date date;
    cursor cur_latest_enrollment_date is
      select max(enrollment_date)
      from   org_body
      where fiscal_yyyy = p_yyyy
      and    fiscal_mm = p_month
      and    student_id = p_student_id
      and    organization_code = p_organization_code;
BEGIN
    open cur_latest_enrollment_date ;
    fetch cur_latest_enrollment_date into t_enrollment_date;
    close cur_latest_enrollment_date ;
    return t_enrollment_date;
exception
    when others then
      null;
end;owever, when I run the following statement below, it takes close to 6 seconds to retrieve a record. In turn, my Query is becoming really slow and taking almost 35 seconds. Imagine that with more records.
select get_join_dates( 2010, '01', '2167543', 'PSYCH01' ) from dual;If I run my query with this condition below, it takes 0.5 seconds.
select s.student_id, s.student_name, s.organization_code
from   student s
where s.student_id = :p_student_id
and      s.student_enrollment_date = '01-JAN-10'Any ideas would be greatly appreciated.

Any reason why you are doing this with the stored function?
You could just do this with SQL. Embed the query in the function as a subquery in your initial query from STUDENT.
select s.student_id, s.student_name, s.organization_code
from   student s
where s.student_id = :p_student_id
and    s.student_enrollment_date =
(select max(enrollment_date)
      from   org_body
      where fiscal_yyyy = :p_year
      and    fiscal_mm = :p_month
      and    student_id = s.student_id
      and    organization_code = s.organization_code);Why your function is not performing: I cannot say that with the information you have provided.
Maybe sqltrace a call and see what the reason is.

IPhoto needs to be upgraded everytime I open it. Then it finds consistences. I have rebuilt the database many times

iPhoto needs to be upgraded everytime I open it. Then it finds consistences. Then it repairs the database.
I have also rebuilt the database many times useing command + alt.
Now it shows every event three times. If I delete one version of that event, it deletes them all.
Then next time I open iPhoto it needs updateing and repairing again
I have used disk utility to repair permissions

Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.
