CPU Time Per User Call / High Or Low?
Aug 10, 2012I've plan to use "CPU Time Per User Call" metrics.
The thresholds are:
Warning: 8000

But this alarm raise every minute.
I think it's too low.But which is the correct value to identify performance problems?

I can't get the data in v$sessstat
Unable to get the information in AWR
dba_hist_active_session_history do not have field which indicate memory related information
Shall I concetrate on EVENT in dba_hist_active_session_history which continuosly had sort, direct path read
Or

Security :: How To Find User And IP Address From Oracle Database
Jun 19, 2013Last week we have realized that a user who connects through SQL Developer(as nothing wrong found in application server logs) has made a serious change in the database which created a real mess. The user has done some mischief in some calculations by making some inserts and updates in some important tables in our production database.
How can I find which user or from which IP the change is made.
Replication :: Oracle Materialized View - High Redo Generation
Nov 15, 2007I have created 5 materialize view with REFRESH FORCE option.
REFRESH is done with every 10 min.
My destination database is MySQL.
DBlink is created in ORACLE 10g
Materialize view is created using DBLINK.
Since refresh materialize view done with every 15 min, my Redo generate gone on toss.System is generating 1 redo file for 1 min. The size for redo log is 500MB.Since materialize views are created base on mysql table, system is doing complete refresh every time which causing to generate more and more redo.
Is there any setting/option/or solution to reduce high redo generation.
Performance Tuning :: Oracle 11g High Memory Usage Dbw0 And Dbw1
Jul 31, 2012We are using the 11g AMM feature and Memory_Target set to 96GB and total RAM on the Server is 128GB Now the top and free shows up only 200MB memory free on the system.
There are 2 process dbw0 and dbw1 which consumes the top memory and this is 30GB per dbw.
Why is the dbw process taking up so much memory when there is not much load on the database.

Find Youngest User In Database?
Feb 6, 2007How do you find the youngest user in a certain table
select a.illness_desc
from uma.pc_illness a, uma.pc_patient b, uma.pc_diagnosis c
where b.patient_no = c.patient_no and c.illness_code = a.illness_code
and b.age = '21';
i currently have this (it also needs to display their illness which i have done) but i can do only if i cheat and see what the youngest user is, so instead of b.age = 21 i need something that will search the database and find that youngest age
we are using SQL+

As of now, the access rights are same for all the windows users logging into the Oracle application with the same Oracle user Id.

We are not looking for the users to be identified externally.

SQL & PL/SQL :: Adding High And Low To Zip Plus Four Values?
Jan 19, 2011I have a table with zip codes and their plus four values. For ex: zip code of 10000, which has corresponding plus four values of 001, 002, 003, and 008, 009, 010. The issue is just that--a zip code can have sequential plus four values, and then it will skip several potential plus four values, and then start again. I would like to assign a low plus 4 value and high plus four value to a zip code, keeping in mind that the plus four values are not always sequential. So, it would be similar to this:
zip plus4 low plus4 high
10000 001 003
10000 008 010

SQL & PL/SQL :: 70% / 30% From High And Low Priority Element
Oct 27, 2011I have a priority column(possible values are 1 or 0) in a table where
i need to get 70% of high(1) and 30% of low (0) and max i can fetch for select is 50 records.
Eg1: Total if i have 60 in which 20 high and 40 low then 70% of 20 = 14 and remaining should be taken from Low i.e. 36 from low. so total will be 50 transactions.
Eg2: Total if i have 60 in which 40 high and 20 low then 70% of 40 28 + remaining should be taken from Low i.e. 22 from Low.
Eg 3: If i don't have any high then total should be picked from low vise versa.
I have below query but it is having problem when there is no low priority.
SELECT ID,PRI FROM temp tbl WHERE pri = '1' AND ROWNUM < ((70/100)*50)+1
UNION ALL SELECT * FROM temp WHERE pri = '0'
AND ROWNUM < 50-(SELECT COUNT(*) FROM temp WHERE pri = '1' AND ROWNUM < ((70/100)*50)+1)
High Availability Of EM-Database Control
Oct 22, 2010I have setup of two node (prod-db1, prod-db2) clustered database 11gR2 on windows 2008 R2 server. Everything is working fine at this setup.
My question is: Is there a way to make the Enterprise manager Database control run and be available at both the nodes independently. What I see that even at node 2 (which is prod-db2) the EM-DBControl is (https://prod-db1:1158/em) - which means the agent is running at node 1 (prod-db1) only.
My question is that how to make the EM-DBControl also run separately at prod-db2. My idea is to make the high availability of EM-DBControl (in case Prod-db1 machine is down).
SQL & PL/SQL :: High Volume Similarity Grouping
Nov 15, 2010I am in the very early planning stages of a project the goal of which is to identify separate organizations which may in fact be the same organization.
Our first implementation of this task was a process designed to look for a few thousand organizations in a pool of a few hundred thousand organizations. To accomplish this we made heavy use of Oracle's Text index as well as a custom index type we created which utilized n-grams. This approach worked quite well for on-demand editing of the organizations, in which a user might log in and say in addition to what we already know about organization A we also know x, y and z does that change anything and worked acceptably well for the bulk processing we did on our "known" information once a week running for a couple of hours on the weekend.
We have now been tasked with reworking this initial implementation only now we want to look at a set consisting of several million organizations for potential matches which exist within the set. As in our initial implementation we will be breaking what we know about organizations into groupings so we aren't comparing a phone number to an email address and normalizing the data as much as we can so we ignore things like case and punctuation. Even after all this we are still talking about looking for similar values in a group which might be in the tens of millions (some types of data will have more than one value per organization).
My initial thought on the problem is to use n-grams though not in the way we did in the past. The basic idea here is that we break the search values up into all the substrings it is made of and look for other values which have a high number of those substrings in common.
SQL & PL/SQL was the best place for the question, but I could not think of a better one.
