Recently we have upgraded from 11.1 to 11.2 . But after upgrade SQL statements that are running fine in 11.1 was running for hours in 11.2. Statistics are collected 100%...

I am using Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - Production
I have 2 schemas in my application.
1. Application schema
2. EOD(End of day) schema.
End of day schema is populated from Application schema whenever user runs EOD process. The tables are pulled like this.
1. Master tables : Always deleted and reinserted at each EOD process
2. Log tables for each transaction table: Delta between the last EOD and current EOD data is pulled and are used for populating transaction tables
3. Transaction tables: These are populated from log tables pulled from previous step. The logic is like this
Now based on these tables about 30 reports are generated in EOD schema. Please note that each transaction table will have a EOD_ID and any report generated uses the where condition <transaction table>.EOD_ID = <current EOD_ID>
My log table contract_log and transaction table is contract in EOD schema.
contract_log table has data like this
contract_number contract_date customer_idqtyrateeffective_date
11/Jan/2010CUST-0110101/Jan/2010
1NULLNULLNULL112/Jan/2010
EOD on 1st Jan 2010 constructs contract table as
contract_numbercontract_datecustomer_idqtyrateeod_id
11/Jan/2010CUST-011010EOD-1
(Since the change of rate 11 is not visible on 1st Jan 2010 because it is effective on 2nd Jan 2010)
EOD on 2nd Jan 2010 constructs contract table as
contract_numbercontract_datecustomer_idqtyrateeod_id
11/Jan/2010CUST-011011EOD-2
(Since the change of rate 11 is visible on 2nd Jan 2010)
This logic is working fine. But we run more than 20-30 EODs the processing time increased to 10-15 hours.
It took some time to figure out the issue as a single query when run from toad or pl sql developer runs in few seconds but as a part of the whole package it takes 2-3 hours(each query).
The problem found was that oracle execution plan gets corrupted when the process starts. So what we did was to analyze the tables
after they are pulled. This perfectly solved our problem. Currently the whole process is taking only about 12-13 minutes where about 3 minutes is lost on analyze tables and indexes. I know this is a temporary solution as I need to get out of online analyze of tables and indexes.
My code for table and index regeneration is as below
PROCEDURE sp_gather_table_index_stats(pc_table_name VARCHAR2) IS
CURSOR cur_ind IS
SELECT index_name
FROM user_indexes
WHERE table_name = pc_table_name;
BEGIN
EXECUTE IMMEDIATE ' begin DBMS_STATS.gather_table_stats(user,' || '''' ||
pc_table_name || '''' || '); end;';
FOR cur_ind_rows IN cur_ind LOOP
EXECUTE IMMEDIATE ' begin DBMS_STATS.gather_index_stats(user,' || '''' ||
cur_ind_rows.index_name || '''' || '); end;';
END LOOP;
END;
From database server, I need to monitor the details about the sql statements which are being currenlt running in client machines.
I tried with V_$SQLTEXT view where I can only see the SQL statements, hash value,address,SQL_id. but I'm not able to get the user name,name the client machine .
find out these details?.Which Data Dictionary i need to use ?.
It started out pretty simple where I had to update about 40 contacts in the database and I would have 40 separate update statements I would run. The task has jumped to about 300 contacts and I don't want to run 300 update statements. I would like to run this all at once. For example:
update contact
set name = 'Name1'
where row_id = 'row_id1'
update contact
set name = 'Name2'
where row_id = 'row_id2'
update contact
set name = 'Name3'
where row_id = 'row_id3'
My DB is oracle 10, and TOAD is version 9.
After Migrating from 11.1 to 11.2 SQL Statements are running for a long time. Our DBA told that they don't have any execution plans for the SQL Statements in 11.1
I don't want to rewrite the SQl Statement as this is working fine in 11.1. Our DBA conveyed us that they are using DBMS_STATS.AUTO_SAMPLE_SIZE for Schema Level.
But we have planned to generate DBMS_STATS.GATHER_TABLE_STATS Estimate Percentage ==> 100 for only the tables that are used in SQl Statements.
Of course we can change the parameters.. But we are afraid it may have some side effects.
Can we execute more than one insert statements at a time (eg 10) in database and givecommit at the end of insert statements or else give a commit one by one after each insert statements ?

View 2 Replies View RelatedI recently performed an upgrade on a new server from oracle 10gr2 to oracle 11gr2 (11.2.0.3).
I take the rman backup from oracle 10g server and restore it on new server where I installed oracle 11gr2.
But on my previous oracle 10gr2 server I enabled the auditing. After doing successful upgrade now when I try to login with any user except sys I receive the following error:
SQL> conn scott/tiger
ERROR:
ORA-00604: error occurred at recursive SQL level 1
ORA-00904: "OBJ$EDITION": invalid identifier
ORA-02002: error while writing to audit trail
ORA-00604: error occurred at recursive SQL level 1
ORA-00904: "OBJ$EDITION": invalid identifier
I got the workaround by setting the parameter audit_trail=FALSE (Previous value was DB_EXTENDED) .But I want my auditing to be enabled as per y requirements.
is the upgrade patch the same for standard edition and enterprise edition or there are two separate patches?

Select * from dba_directories; (there are other commands to get this info as well).
I captured screens from the DBUA upgrades, but did not see an option to change this information.Is there a way to feed this information to the install moving forward. IE, ./DBUA -silent ?
Also, anyone tracked the percentage of storage increase from 10.2/11.1 to 11.2.
All my sys tables are very slow after my database upgrade from 10.2.0.4 to 11.2.0.3 on AIX 6.1
For example
select * from ALL_TAB_COLUMNS; -- taking 19 seconds in 11.2.0.3 and few millisec in 10.2.0.4
I have deleted and updated fixed and dictionary table statistics , till I facing this issue

View 1 Replies View RelatedI am going to upgrade database from 11.1.0.7 to 11.2.0.3
1) If compatible is set to 10.2.0 in 11.2.0.3, will it work ?
2) If compatible set to maximum level, will it affect our application ?
3) Whether any code related problem occurred after upgrading like PL/SQL codes ?
We are planning to upgrade our database from Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bi to Oracle Standard Edition 11g . We also have oracle apex installed on Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bi database with oracle apex 3.1
No our plan to upgrade the database and oracle apex to 4.2. Since Oracle Enterprise Edition is licensing is very expensive we though of buying standard edition and upgrade to this version.
can we upgrade the oracle database from enterprise edition to latest standard edition?
Iam doing some oracle database upgrade from 9.2.0 to 11gr2 . is it possible to upgrade directly from this 9i version to 11gr2 .
Version : 9.2.0 to 11gr2
Why COMPATIBLE Parameter is important to be at a certain value before you UPGRADE(10.2.0.4 to 11.2.0.3) to 11g ?

I want to write a function that gets:
1. event_date (dd/mm/yyyy)
2. event_start_time (??/??/???? HH24:MI)
3. event_end_time (??/??/???? HH24:MI)
I got a table called EVENTS that got 2 fields:
1. event_date (dd/mm/yyyy HH24:MI)
2. event_end_date (??/??/???? HH24:MI)
and want to check if there is an event in my EVENTS table that occurs in the same dd/mm/yyyy as the input, and can disturb the input event times. means:
input.event_start_time is between EVENTS.event_date
and EVENTS.event_end_date
and
input.event_end_time is between EVENTS.event_date
and EVENTS.event_end_date
but to compare only the hours here! (HH24:MI)
because the date (dd/mm/yyyy) is checked before..
I don't know how to cut only the hours out of the date and compare them, and don't know how to write the whole function.
I have a table which will the following type of data
"COL1""COL2"
1001"27-DEC-2010 02:00:00"
1002"27-DEC-2010 07:00:00"
1003"27-DEC-2010 09:00:00"
1004"27-DEC-2010 02:00:00"
1005"27-DEC-2010 12:00:00"
Here you can see that we have data for 27th Dec 2010 02,07,09 and 12 hours. I want a query which will show the full 24 hours data even if it doenst have any records. like the following,
COL1 COL2
0 2010122701
1001 2010122702
1004 2010122702
0 2010122703

I have a field in Customers table called shipeddate....
I wnat to check the number of hours an item which has a shipeddate is in the store room to the current datetime...
But the business hrs of the store room are from 8am-5pm..
So when a shipped date is 4pm on MOnday
and i am checking on 9 am Tuesday the number of hrs shud be 1(4-5 of Monday)+1(8-9 of tuesday) =2hrss..
How can i achieve this...
i am using one query but not getting correct minutes.
here is my query:
v_Interval:= to_timestamp(v_temphrs,'HH24:MI:SS')-to_timestamp(v_outpunch1,'HH24:MI:SS');
v_TotalHrsMin1 := extract(hour from v_interval) * 60 + extract(minute from v_interval);
here v_interval datatype is "interval day to second" and v_temphrs datatype is varchar2 and value is : 12:00:00 and v_outpunch1 datatype is varchar2 and value is: 06:10:00
and v_totalHrsMin1 datatype is number.
here i should get value 370.
but i am getting value 350.
I am using the below sql query to calculate working hours. The problem which i am facing is that query is taking lot of time to calculate the working hours. reduce the execution time of this query or if there is any other way to calculate working hours
The following query take 63.499 sec
SELECT sql_calc_found_rows gstime,
MAX(stoptime) AS mx,
MIN(starttime) AS mn,
[Code].....
I want to convert below MS-SQL query in oracle 10g.
for eg:
Select numasdate,
Cast(numasdate / 60 as Varchar) + ' hours ' +
Cast(numasdate % 60 as Varchar) + ' minutes'
as [TotalHoursAndMinutes]
From
#SampleTable
Output:
9436 157 hours 16 minutes
537 8 hours 57 minutes
9323 155 hours 23 minutes
12525 208 hours 45 minutes
I have a table with a date field. This field storage dates with hours like this:
01-08-2012 8:30:00
01-08-2012 8:15:00
01-08-2012 9:30:00
01-08-2012 9:40:00
02-08-2012 8:30:00
02-08-2012 9:30:00
02-08-2012 9:34:00

I have to generate a report with the day and the frequency :
__Day_______ Hour Range__CountRecords
WEDNESDAY 8 - 9 2
WEDNESDAY 9 - 10 2
THURSDAY 8 - 9 3
The block of the hour must be 1 hour (8-9,9-10 and so on)
how generate the hours range.
My database oracle version is 8i. (I know that is very old but I can't change because It´s a legacy system).
I am not getting added hours from results.
SELECT audittimestamp + interval (SELECT EXTRACT(TIMEZONE_HOUR
FROM systimestamp) FROM DUAL) hour from tab1I want to add Timezone_hour to my timestamp.
I am fetching data which are older than 2 hours from now. TRANSACTION_TIME is varchar2 field in "MM/DD/RRRR HH:MI:SS PM" format.
SELECT * FROM TRANSACTION_DETAILS
WHERE TO_DATE(TRANSACTION_TIME,'MM/DD/RRRR HH:MI:SS PM') <(SYSDATE - 2/24);
Is there anything wrong in the query.
format of dtActivityStartDate/dtActivityFinishDate: 2010-09-17 14:50:51.150 Note: Both dtActivityStartDate/dtActivityFinishDate
vcActivityName = Process Request
usdFuncTimeCalc (vcActivityName,dtActivityStartDate, dtActivityFinishDate)
i need to calculate time elasped for that type of activity following are the rules:
(If Process Request is the activity)
Working Days: Monday through Saturday
Hours of Operation: 9AM 5PM
only working hours of day need to the counted like for example if it is sep 15 11 Am is dtActivityStartDate & Sep 17 is dtActivityFinishDate is 10 Am. then time elapsed is 11am to 5pm on sep 15 , 9 to 5 on sep 16 & 9 to 10 on sep 17 so total should be
6+ 8 + 1 = 15 hours + minutes.
format of date time: 2010-09-17 14:50:51.150
vcActivityName = Process Request
Don't worry about process request..
I want to validate dynamic hours value using decode in sql...
If value is greater than 24PM it should display some statement...
if value is less than 0AM it should display some statment...
I have the following code which will produce a list of dates -
SELECT to_date('01-Jan-2013','DD-Mon-YYYY') + rownum - 1
FROM all_objectsWHERE rownum <= to_date('31-Jan-2013','DD-Mon-YYYY') - to_date('01-Jan-2013','DD-Mon-YYYY') + 1 01/01/201302/01/201303/01/201304/01/2013.....30/01/201331/01/2013
But what I'm looking for is a way to also include all possible hours with the dates, so my output would be like -
01/01/2013 0001/01/2013 0101/01/2013 0201/01/2013 03...31/01/2013 2131/01/2013 2231/01/2013 23
