Number Of Waits Reaches To 100 In 8-hour Snapshot

Oct 8, 2013

in the awr report I saw some segments in Segments by ITL Waits section. Number of waits reaches to 100 in 8-hour snapshot. Is it small/big number? Should I consider increase INITRANS or there is nothing to be worried because value 80-100 are not too high?

SQL & PL/SQL :: How To Manipulate Greater Than 24 Hour Clock In Oracle

Jul 14, 2011

I have an Oracle application that deals with a 29 hour clock. so the days begin at 5am instead of midnight. I am trying to get data from a table where time is up to certain number of hours, but when it reached the 00 clock my whole query returns no records, even though there is plenty of records before the midnight hour, because the data is saved as lets say 2530 instead of 0130

I am using this

SELECT *
FROM WORK.WORK_UNIT
WHERE (to_char (current_garage) = :entry_blk.curr_garage
OR 'all' = :entry_blk.curr_garage)
AND route >= 0 AND run >= 0
AND ((package_id > 0 and work_code = 99) OR
(package_id is null and work_code = 1))
and Nvl (Emp_No, 0) = 0
AND work_date = :entry_blk.p_work_date
AND on_time <= TO_CHAR(SYSDATE + :Entry_Blk.up_to_hour/24, 'HH24MI')

since oracle deals with a 24hour clock, my code doesn't seem to work if there is data for after midnight (00 hour). I am using :Entry_Blk.up_to_hour/24 to determine up to how many hours I want to see data, i.e.

on_time <= TO_CHAR(SYSDATE + 2/24, 'HH24MI')
will give me data up to 2 hours

SQL & PL/SQL :: Time Range Include A Specific Hour?

Aug 11, 2010

I'm looking for a way to say if a time range includes a specific hour.

If I was looking to work out if 01:00 to 04:00 includes 02:00, then this works:

CASE WHEN TO_DATE('02:00','HH24:MI') BETWEEN TO_DATE('01:00','HH24:MI') AND TO_DATE('04:00','HH24:MI') THEN 1 ELSE 0 END

But, if the time go over two days (with midnight in between), it doesn't work:

CASE WHEN TO_DATE('02:00','HH24:MI') BETWEEN TO_DATE('18:00','HH24:MI') AND TO_DATE('04:00','HH24:MI') THEN 1 ELSE 0 END

Generating ADDM Reports Automatically Every Hour?

Jun 9, 2012

I have been trying to develop a script for generating ADDM Reports every hour and save it in a directory on the server. I was able to develop a script to run the AWR Reports for every hour and save them in a directory, but I ran into troubled waters in the ADDM script.

Database Version : Oracle Database Enterprise Edition 10.2.0.3
OS : IBM AIX 5.3

I'm trying to debug the script below to generate ADDM reports on a per hour basis and save them in a folder as well as mail than to a particular entity.

########################################################################################
# Set up Oracle environment variables...
#------------------------------------------------------------------------------
export PATH=/usr/bin:/etc:/usr/sbin:/usr/ucb:/oracle/app/oracle/product/10.2.0/bin:/usr/bin/X11:/sbin:.:/oracle/app/oracle/product/10.2.0/bin
export ORACLE_HOME=/oracle/app/oracle/product/10.2.0
export ORACLE_SID=sarcotest2.ora
export ORAENV_ASK=NO

[Code].....

Initially, the script did return me an ADDM report, but the problem was that it generated the report for only a set of two snapshots (eg: 410110 and 410111). later when the snapshots advanced further, it still generated the same report for the same snapshots.

Now, it seems it have made several changes to the script in the declare and dbms_advisor section and the reports are not being generated anyway.

One problem I am facing is

ORA-13605: The specified task or object ADDM_UAT does not exist for the current user.
ORA-06512: at "SYS.PRVT_ADVISOR", line 2043
ORA-06512: at "SYS.DBMS_ADVISOR", line 560
ORA-06512: at line 1

It seems the task is not being generated at all in my user's schema.

PL/SQL :: Query Returning Zero Results For Yesterdays Same Hour

Apr 22, 2013

I have the following query:

SELECT
d_dtm,
BTS_ID,
CASE WHEN D_DTM = (D_DTM-24/24)
THEN sum(V_ATT_CNT)

[Code]....

But it is not returning any results because of the "having" clause. I know it should return results because all I want it to do is in one column have the V_ATT for the current time period, and in the 2nd column, have the V_ATT 24 hours ago. I've checked the data and I should get results back but can't seem to figure out why this is not working...

SQL & PL/SQL :: Display Date Ranges In One Column As Separate Date Periods (start And End Date) In Two?

Jun 1, 2010

I'm trying to work out how to take a table like this:

IDDate
12502-Feb-07
12516-Mar-07
12523-May-07
12524-May-07
12525-May-07
33302-Jan-09
33303-Jan-09
33304-Jan-09
33317-Mar-09

And display the data like this:

IDPeriodPeriod StartPeriod End
125102-Feb-0702-Feb-07
125216-Mar-0716-Mar-07
125323-May-0725-May-07
333102-Jan-0904-Jan-09
333217-Mar-0917-Mar-09

As you can see, it's split the entries into date ranges. If there is a 'lone' date, the 'period start' and the 'period end' are the same date.

Group Records With Less Than One Hour Separation And Count How Many Per Group

Nov 1, 2013

I'm trying to group sets of data based on time separations between records and then count how many records are in each group.

In the example below, I want to return the count for each group of data, so Group 1=5, Group 2=5 and Group 3=5

SELECT AREA_ID AS "AREA ID",
LOC_ID AS "LOCATION ID",
TEST_DATE AS "DATE",
TEST_TIME AS "TIME"
FROM MON_TEST_MASTER
WHERE AREA_ID =89
AND LOC_ID ='3015'
AND TEST_DATE ='10/19/1994';

[code]....

Group 1 = 8:00:22 to 8:41:22

Group 2 = 11:35:47 to 11:35:47

Group 3 = 15:13:46 to 15:13:46

Keep in mind the times will always change, and sometime go over the one hour mark, but no group will have more then a one hour separation between records.

PL/SQL :: Query To Extract Changes

May 7, 2013

I am using Oracle database version 11.2.1 and would like to extract the level change and level start date where reason_code is 'PROMO' split by ID.

The test script is below:

id number,
start_date date,
reason_code varchar2(10),
level number
)
insert into test values(001, '01-JAN-13', 'PROMO', 2);

001, 2, '08-MAR-13' , 3, '05-MAY-13'
002, 4, '13-APR-13' 5, 02-MAY-13'
