Flag Or Monitor CPU Utilization?
Dec 22, 2010
I have to run a resource extensive SQL. It utilizes CPU to a great extent. I've created a new user just to run this particular report. I need to ensure that this particular user doesn't uses more CPU.
Hence, I need to generate an alarm (email) only if a threshold is exceeded for a certain period of time (above x% for y minutes),(example more than 80% for 10 min.), so that I can either kill the process or continue running it depending on CPU usage.
Can I do it using scripts or OEM. I couldn't find any specific metrics to do it in latter. (I'd prefer scripts though. )
My system details are as follows:
1. Database: Oracle 10g R2
2. Unix: Sun OS 5.10

Recently we have upgraded to 11g(11.2.0.3) from 10.2.0.2 on AIX 5.1 enviornment. After upgrade, it has been noticed that CPU utilization is more while executing a program.
CPU is crossing 85% in 11g, in 10g it is 60% during the program execution. I have gone through the SQLs which are getting executed, elapsed time for all SQLs are less than in 10g. i.e. elaspsed for all SQLs in 11 is very less. in AWR report, DB CPU stood in the top.

I had one of my RAC nodes go down due to a disk failure. I have a 3 node cluster running 10.2.0.4 on Dell 610's running Windows Server 2008. I have been running AWR reports this afternoon and am seeing CPU time as my top timed event. Here is the exerpt from the report I am looking at:
Cache Sizes
~~~~~~~~~~~ Begin End
---------- ----------
Buffer Cache: 20,032M 20,032M Std Block Size: 8K
Shared Pool Size: 12,688M 12,688M Log Buffer: 6,336K
[code]...
I wanted to ask if there was anything that I could be doing to alleviate the workload on the 2 remaining nodes right now? As far as I understand it there is no way to stop users from hitting the database and without my 3rd node to load balance the CPU will continue to be pegged until the end of the day as the users are logging off.

I am not a DBA, we are using Oracle 10g DB for our PLM applictaion Enovia, we are now trying to do 4GT in our windows 2003 server where our DB kept, while reading articles about this. we are informed that /LARGEADDRESSAWARE (IMAGE_FILE_LARGE_ADDRESS_AWARE) flag needed to be set to True in the application (here it is Oracle) to use more than 2GB in the RAM.
So My question is "Whether the corresponding flag is set to TRUE or not in Oracle 10g"? Is there any way to check that?"

we are running a 2 node rac database of oracle 10.2.0.4 in aix 6.3. The shared pool utilisation goes up when we run our jobs and sql statements. But it does not come down. It been 2 gig for over 3 days without any processes running.
Is there a threshold time period after which oracle will release the space utilisation from the shared pool????

I have records like the following
Program_Name Effective_Date Valid_Flag
ABCD 2/10/2012 N
ABCD 2/14/2012 N
ABCD 2/20/2012 Y
ABCD 3/01/2012 N
ABCD 3/10/2012 N
[Code]...
I have to write a select statement to to keep the first record and then pull only the records when the Valid_Flag changed. The result set should be like below.
Program_Name Effective_Date Valid_Flag
ABCD 2/10/2012 N -- I have preserved the first record
ABCD 2/20/2012 Y -- Valid_Flag chages to a Y for teh first time and so on.
ABCD 3/01/2012 N
ABCD 3/14/2012 Y
ABCD 3/25/2012 N
ABCD 4/25/2012 Y
If there is no change in the flag, I do not have to pull that record.

I have a scenario, where I need to find the bucket values with the flag as "Y". The problem is i have 5 buckets
Bkt1 Bkt2 Bkt3 Bkt4 Bkt5 Flag
------------------------------------------
1000 500 230 100 677 Y
789 100 122 666 888 N
783 110 142 166 788 N
781 110 112 616 988 Y
709 130 121 661 878 N
Here I need to write a SQL query in Oracle 10g fetching the respective bucket value(for all the 5 buckets) along with the flag as "Y" and more importantly should have the bucket name as well.This is needed as in the UI we need to display the respective bkt value which is "Y" as bold.
So in the final List I need to have the VO which should contain the respective bucket name, respective value and flag as "Y"
Some thing like this I need to get in my final ArrayList in java
Bkt1 1000 Y
Bkt1 781 Y
Bkt2 500 Y
Bkt2 110 Y
Bkt3 230 Y
Bkt3 112 Y
Bkt4 100 Y
Bkt4 616 Y
Bkt5 677 Y
Bkt5 988 Y
how we can do it using the SQL query.

I am working on an archiving strategy. I want to roll off transactions that are older than seven days, but only if they are flagged as Completed. The numbers of transactions are very large so this is a worthwhile venture.
The only strategy I have been able to come up with so far is to partiton on date. Then when 7 days comes up, sweep the about-to-be archived day for the few remaining not Completed transactions, put those into a new table (a new version of this partiton) and switch partitions. Each day I do this until the older parititions are empty.

I would like to update the complete flag of all the rows of a table except the most recent two rows of each category.
The table has fields like:
category - string,
item - string,
creation_date - string ('YYYYMMDDHHMI'),
complete_flag - boolean,
etc.
Each category does not have the same amount of records with the same creation_date so I do not want to filter by creation_date. Is there a way to accomplish this?

In a 3-node RAC setup; one node is showing high CPU utilization around 40~50%. The CPU utilization was less than 20% 10 days back but from 9th oldest day it jumped and consistently shows the double figure. I ran AWR reports on all three nodes and found one node with high CPU utilization and shows below tops events-
EVENT WAITS TIME(S) AVG WAIT(MS) %TOTAL CALL TIME WAIT CLASS
CPU
time 5,802 34.9
RFS
ping 15 5,118 33,671 30.8 Other
Log file sequential
read 234,831 5,036 21 30.3 System I/O
Sql*Net
more data from
client 24,1711,08745 6.5 Network
Db file sequential
read130,939 4533 2.7 User I/O
Findings:-
On AWR report(file attached) for node= sipd207; we can see that "RFS PING" wait event takes 30% of the waits and "log file sequential read" wait event takes 30% of the waits that occurs in database.
1)Are these symptoms of undersized log buffer?
2)I feel Network wait can be reduced by tweaking SDU & TDU values based on MDU.

The stand alone stored procedure has 2 parameter, an IN and OUT...
CREATE OR REPLACE PROCEDURE someprocedure( businessdate IN NUMBER,
tablename OUT VARCHAR2)
This procedure has multiple inner blocks. Intention is to control execution of each of the inner blocks basing on the value of flag field obtained from a "processlogtable". This processlog table has structure as below.
jobname varchar2(100)
controldate (date)
controlflag varchar2(1)
I have the below code snippet at the beginning of each inner block that checks value of the flag and then proceeds with execution of that block. The intent is to avoid redundant call of a block that has successfully executed first time. That is, once a specific inner block fails for some reason, the re-execution of the stored procedure should AVOID re-executing the PRIOR successed steps.
I've the code set up as below, but the prior successed block(s) code gets re-executed again once the procedure is re-executed after a failure.
CREATE OR REPLACE PROCEDURE someprocedure( businessdate IN NUMBER,tablename OUT VARCHAR2)
CURSOR c_missingtablename
IS
SELECT datatablename
FROM (
SELECT UPPER(datatablename ) TABLE
FROM
WHERE datatableName IN ('Aaa','BbB','CcC');

I am looking for a way to monitor the creation of new datafiles / tempfiles.Let's say I am creating a new datafile of 8GB in size, and it takes a few minutes to create.
I have looked at v$session_longops, and several other system views, but cannot find any that indicate how the file creation is progressing.
I want to be able to display something simple, such as "72% complete".

Many moons ago, at a previous employer, I had access to the SQL Monitor tool that came with TOAD. I could really use an alternative to this now, as we don't have TOAD here, and it would need to be free. I'm getting a problem with a forms update failing, and I really need to see what's actually being submitted to the database by the form. We're still stuck on Forms 6 by the way

I am using basic replication in oracle 10.2.0.3. My materialized view object contains around 3 million records. Usually we are using FAST refresh but in my materialized view having some problem that’s the reason I am going to Complete refresh.
If I start complete refresh it will take 8-12 hours to complete refresh.
My Question is: During Complete refresh how to monitor complete refresh running or not except using
v$mvrefresh.
Is there any way to monitor complete refresh because suppose target database not available/network problem/ dead lock occur in my database. I can’t able to track refresh.
Even there is no notification in alert log.

I can use trigger to monitor ALTER TABLESPACE ddl statement against a particular tablespace in a schema.
CREATE OR REPLACE TRIGGER HOT_MAIL_DDL_CHANGE
AFTER ALTER TABLESPACE <tbs_name>
ON SHANNURA.SCHEMA
BEGIN
INSERT INTO HOT_MAIL_DDL_AUDIT_LOG VALUES
(SYSDATE,
SYS_CONTEXT('USERENV', 'SESSION_USER'),
ORA_SYSEVENT,
ORA_DICT_OBJ_TYPE,
ORA_DICT_OBJ_NAME
);
END;
/
I think, line no.2 isn't a valid statement. Or can I use AUDIT instead - in fact, I want to monitor/audit only ALTER TABLESPACE ddl statement and that too for a particular tablespace only.
