I have a mview based on the database link. Mview created without the error and first time refrehment has been done properly in time, but after the first time it is not refreshing.
CREATE MATERIALIZED VIEW "SMSCHAT"."TBL_VOICECHAT_NEW1"

I have set the refreshment time for mview for 15 min with the following command
alter MATERIALIZED VIEW SMSCHAT.TBL_VOICECHAT_NEW1 REFRESH FAST START WITH sysdate+0 NEXT sysdate+(15/86400*60);
But now this mview is not refreshing and no jobs is showing in dba_jobs_running.

My Oracle jobs are not running. I can run them manually but they don't start automatically as per interval. The job_queue_processes=100 and CJQ process is not running. I started CJQ0 process by resetting it to 0 and then to 100. But as soon as I enabled a job this background process stopped.
The job also did not execute in its next execution time. I have created the database manually without using DBCA. Is the problem because of this? I have set crontab immediately to get rid of it.

"Oracle parse sql and stores explain plan, if the same sql comes again then oracle don't parse it again (soft parse) and gets the explain plan through cursor sharing."
Is there any parameter through which I can set cursor_sharing refresh interval to generate new execution plan?

I am studying Oracle® Database VLDB and Partitioning Guide 11g Release 2 (11.2),
ORA-14767: Cannot specify this interval with existing high boundsby giving an example other than given in the above mentioned document.
the example given in the document is as follows:
To increase the interval for date ranges, then you need to ensure that you are at a relevant boundary for the new interval. For example, if the highest interval partition boundary in your daily interval partitioned table transactions is January 30, 2007 and you want to change to a monthly partition interval, then the following statement results in an error:
CREATE TABLE transactions
( id NUMBER
, transaction_date DATE
, value NUMBER)
PARTITION BY RANGE (transaction_date)

One user complained that, his session is closing automatically when his session exceeds exactly 01 hour 1 minute.
default profile is assigned for this user. I checked the idle_time value of this default profile. it is UNLIMITED only. What else I need to check to find out is there any timeout parameter has been set or not?

i have to divide into 3 groups and take a count 7am-12pm, 12pm-7pm, 7pm-7am groups
It looks so complicated to me, because IN time and OUT time together how we do it.
suppose one person 6am IN and out 8PM means he will be in 7am-noon , noon to 7pm, 7pm-7am -- 1, 1 1 on 3 interval another scenario is if one person in 2am in the morning it has to be previous days count. Is this possible to do it in query.

I'm having trouble using interval data types in a procedure. I need to pass a number of minutes as a parameter, and then use them for arithmetic on a timestamp with time zone. This works no problem:
set serveroutput on
create or replace procedure tstz(mins varchar)
as begin
dbms_output.put_line(systimestamp - interval '10' minute);
end;
[code]...
I've tried a few variations of data type and type casting for the parameter, but I can't make it work.

I have a procedure I need to feed a number into in order to generate some thumbnails.
I'm trying to automatically update the value every time a new row is inserted but I'm having trouble with the code.
DECLARE
varInt NUMBER :='SELECT MAX(IMAGE_ID) FROM IMAGES';
begin
create_blob_thumbnail(varInt);
end;I get the error +'ORA-06502: PL/SQL: numeric or value error: character to number conversion error'+
If I run the query SELECT MAX(IMAGE_ID) FROM IMAGES, it returns the last row ID I created just as it should. The create_blob_thumbnail(varInt) procedure works fine if I manually put in a number.

I have created a job using DBMS_SCHEDULER with named schedule.
After i have modified the schedule using the below queries,
exec dbms_scheduler.disable( 'JOB1' );
exec dbms_scheduler.set_attribute_null('JOB1','schedule_name');
exec DBMS_SCHEDULER.SET_ATTRIBUTE( name => 'JOB1', attribute => 'repeat_interval', value => 'freq=WEEKLY;BYDAY=SUN,WED,FRI;BYHOUR=05');
exec dbms_scheduler.enable( 'JOB1' );
I am using the client system to change the setting and the time zone differs from that of production. Even though the job is scheduled to run at 5 AM it show the start date as 6:30 PM which is the client system time.
