I have the below scenario:
[u]Report_Time M I Ta[/u]
02-SEP-13X Y35167005
01-SEP-13X Y35931902
03-SEP-13X Y35931901
The output I am expecting from above is:

II need to extract minimum report time , max report time and corresponding Ta.
1) Extaract time from date field
2) Extract minute form that time ..
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

We have scheduled some Jobs such as monthly, semi-annually reports using dbms_scheduler. we use 10gR2 software and windows 2003 server. we have a report which supposed to run at 4:00 AM and as soon as the report finishes it sends the report as email to the authorized users. when the scheduler ran the report inside the report it shows as ran at 3:08 AM where they get systimestamp. but when i query the
select last_stat_time, next_run__date from dba_scheduler_jobs where job_name ='TEST';
last_start_time next_run_date
03-DEC-12 04.00.00..223000 AM -04:00 07-JAN-13 04.00.00..200000 AM -04:00
when I query systimestamp from dual on that database from sqlplus:
i get the following:
systimestamp
04-DEC-12 07.40.16..152000 AM -05:00
I see the difference of -04.00 and -05.00 from both of the queries. i know the systimestamp from dual is correct. how to I fix the scheduler Job to run at the correct time with daylight savings to take effect?
Till statspack we had
elapsed time = time spent on waits + time CPU was used
Total time during snaps = Elapsed time + (may be) time waited for CPU...In AWR is it possible to draw such equation? I can see that the AWR report has following elements
1) End Snap time - Begin Snap time
2) DB time - as mentioned at the top of AWR report
3) DB CPU - in "Top 5 Timed Foreground Events" (I assume this is 'CPU used by sesson timing' in statspack)
4) Total of time for all Statistics in "Time Model Statistics"
5) BUSY_TIME + IDLE_TIME - "Operating System Statistics"
Time between 2 snapshots? or what else? Also for which seconds to multiply to 'DB Time(s)' per second and 'DB CPU(s)' per second in Load Profile to get the db time and CPU time?
I understand that when data is read from the disk, I/O is done..And When computations are done then CPU is used..Then where the following equation fits?
DB Time = sum of database CPU time + waits
Is I/O considered as a part of CPU time?
Does this equation changes with SAN, OS caching?
I have an AWR report based on two snapshots one an one hour time window, under the "SQL ordered by Elapsed Time" section, there is a query having Elapsed Time = 7012 seconds, which is almost two hours, how is this possible? I have been told that this i aggregate value of all sessions.
View 3 Replies View RelatedI want to make report of processing time for tasks. Every task has several stages and connected with them modification dates. I need calculate total processing time for every task.
In my calculations i have to consider only "working" hours. There is time window table (For example working hours: from 8 a.m to 4 p.m, but can be different thats why i use table with id - different id = different time window). Scripts i used to simulate problem:
create table t (
id number,
s_date date,

table t constrains "working" hours:

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 have a table structure as follows Student(Id,First_Name, Last_Name, email, Contact, Address1 ,Address2, City, Edit_Date,Create_Date,Archived)
Now if there is more than one row with same email the one with the latest edit date should be updated with missing fields by using same field value other rows (if the field is present in more than one row, the one with the next latest edit date is to be considered) and
the archived status of all rows with same email except this master row must be set to 1.The Create_Date must be set to the minimum of all the create_date values of rows with same email value
I have a page which downloads statspack reports from different servers and stores them in APEX. As well as this it also display a summary of data (top 5 wait events & load profile info) when hovering an icon: [URL]... The chart will refresh itself and display the data based on the value of P10_SNAPVAL (storing the PK value). The report does not do as I expect it to do (it isn't refreshing the table). I have the following:
PL/SQL Dynamic Content region making the report Dynamic Action- Event: Change- Item: P10_SNAPVAL- Action: Refresh- Affected Element: Region - Load Profile (the PL/SQL Dynamic Content)- Event scope:
I've tried both bind & live The value of P10_SNAPVAL is changed whenever the user hovers a penguin icon (this works because the chart works).

into try_o values (1,2,'f1',5)

I need to get the row that contains the least pk2 among the group of records with the same fld1 and fld2. but if I used
select min(pk1), min(pk2), fld1, fld2
from TRY_o
group by fld1, fld2;
I get a record that doesn't exists as the min(pk1) and min(pk2) are from different records. I need to get the min(pk1) and its corresponding pk2.

Here the GROUP is changing when the data type is changing and thus for same data type the group shall remain the same As of now this is achieved by - first selecting distinct object_type, then it's mod(rownum,<input variable) and this result of 'mod' is doing the grouping which is the retrieved along with rowid of all individual record
Present query is as following and it is not much efficient
SELECT DO.ROWID RWID, RID
FROM DO,
(
SELECT OT,CASE MOD(ROWNUM,:v) WHEN 0 THEN :v ELSE MOD(ROWNUM,:v) end as RID
FROM(
(SELECT DISTINCT OBJECT_TYPE OT
[code]....
I tried using sequence with cycle but it gave different results. Even I tried following but it did not gave satisfactory results
select d.rowid,d.object_type,x.x1 from do d,(select distinct object_type,mod(rownum,:v) x1 from do where
created>'01-jan-2008')x where d.object_type=x.object_type and created>'01-jan-2008';
In short the query needs Distinct with mod(rownum) and individual records in a single pass The mod(rownum) i.e. group shall change when the object_type changes but then shall remain constant through out the particular object_type.
I am trying to restore to a backup instance on a backup server. When I try to recreate the tables I keep getting ORA-01659: unable to allocate MINEXTENTS. The tablespaces and datafiles on both servers show as the same size in OEM.
I have dropped all tables and OEM shows tablespaces are empty. Then I run a script to recreate all tables. Most of the tables don't get created because their TS is full. After the script to recreate all tables runs, the main tablespaces are full, more full than on the production machine. I have also tried ALTER TABLESPACE xxx COALESCE; on each tablespace right after dropping all tables and before recreating them to reclaim free space. Why is it full? I've only dropped and created the tables, there shouldn't be any data in them yet.
ORA-01659: unable to allocate MINEXTENTS beyond 2 in tablespace PLUS_T...The backup instance was already there, all I did was drop the tables. Here's what I ran on prod to build a script to recreate the tables on backup server. Got it off Burleson somewhere.

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 a requirement where the data between [] or ][ has to be extracted from a string.
