%CPU Value on plan_table_output
Does anyone know how the %CPU value is calculated when using dbms_xplan.display in oracle 10g?
I'm sure it comes from plan_table (v$sql_plan) but I can't figure out how the value is calculated...
Thanks

"COST: Cost of the operation as estimated by the optimizer's query approach. Cost is not determined for table access operations. The value of this column does not have any particular unit of measurement; it is merely a weighted value used to compare costs of execution plans. The value of this column is a function of the CPU_COST and IO_COST columns.
CPU_COST: CPU cost of the operation as estimated by the query optimizer's approach. The value of this column is proportional to the number of machine cycles required for the operation. For statements that use the rule-based approach, this column is null.
IO_COST: I/O cost of the operation as estimated by the query optimizer's approach. The value of this column is proportional to the number of data blocks read by the operation. For statements that use the rule-based approach, this column is null."
You could try to perform a test like the following:
1. Create a dummy table named T1, in my case I am using a test table with 100,000 rows.
2. Experiment:
EXPLAIN PLAN FOR SELECT COUNT(*) FROM T1;
Explained.
SELECT
ID,
CPU_COST,
IO_COST,
COST
FROM
PLAN_TABLE;
ID CPU_COST IO_COST COST
0 13331709 11 13
1
2 13331709 11 13
SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY);
Plan hash value: 2552807428
| Id | Operation | Name | Rows | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 1 | 13 (16)| 00:00:01 |
| 1 | SORT AGGREGATE | | 1 | | |
| 2 | INDEX FAST FULL SCAN| SYS_C0020571 | 100K| 13 (16)| 00:00:01 |
------------------------------------------------------------------------------From the above, the total cost of ID 0 is 13, of which 11 is the IO cost. Therefore, the CPU cost is 13-11 = 2. 2/13 = 15.38%. 15.38% rounded up is 16%. That might be the meaning of the %CPU column in the DBMS_XPLAN output.

Process Snmp (PDU Dispatcher) causes High CPU value
Hello,
I have a Catalyst Switch 6000. Inoticed that after the execution of the job inventory in LMS, and after the snmp queries reached the equipement, the cpu value reached 98-99 % due to the process : PDU DISPATCHER (what’s it ?)
I have also a script running in the switch to observe the differents logs. For exemple, when high cpu is obtained, the message bellow appear :
« %SNMP-3-INPUT_QFULL_ERR: Packet dropped due to input
« %SNMP-3-INPUT_QFULL_ERR: Packet dropped due to input
« %SNMP-3-INPUT_QFULL_ERR: Packet dropped due to input
Could you give me any idea or help ?
Thanks in advance.This msg is normally generated when to many snmp request overrun the buffer allocated for such requests. There are a number of things that can cause this as well as a number of known issues that can be worked around using snmp views. Without reviewing show logging and other information available in a show tech, hard to say what the best method to resolve this. Should probably open a TAC SR to troubleshoot the issue further...

Powershell command to get cpu percentage as displayed in task manager
Hi,
I wish to extract the memory and cpu data of each process as shown in task manager. I am able to get the memory size in mb, but
PercentProcessorTime does not return the exact process's cpu % value shown in task manager.
function GetProcessInfoByName ([string]$processName)
Get-WmiObject -class Win32_PerfFormattedData_PerfProc_Process | where{$_.name -eq $processName} | Select-Object
@{Name="Process Name"; Expression = {$_.name}},
@{Name="CPU (%)"; Expression = {$_.PercentProcessorTime}},
@{Name="Memory (MB)"; Expression = {[Math]::Round(($_.workingSetPrivate / 1mb),2)}}
Get-Process | ForEach-Object {$proc = $_; GetProcessInfoByName $proc.Name} | Format-Table -AutoSize
Please help! Thanks.You'll find that determining the exact CPU usage is very difficult because of the always changing value and also because you want an average, not a peak at a particular point in time.
As an example, on my task manager my powershell_ise was never consuming 12% CPU (not even 1%), that was a peak that got caught by the script (as seen in my screenshot above).
I found I get more consistent results (not perfect though) with this variation of the script, which uses Get-Counter to query information:
$CpuCores = (Get-WMIObject Win32_ComputerSystem).NumberOfLogicalProcessors
(Get-Counter "\Process(*)\% Processor Time").CounterSamples | Select InstanceName, @{Name="CPU %";Expression={[Decimal]::Round(($_.CookedValue / $CpuCores), 2)}}
The only problem here is that this does not give you the memory, which is something you're also after.
And while you could join it to the results of the memory retrieved in another way, it doesn't return a PID, just a process name so if you have same many instances of the same program open... you'll get into trouble trying to match them.
You could of course just join them all as one and say... I have 20 powershell.exe processes open and as a whole they're using 10% CPU and 200Mb ram, but that might not be what you're after... -
Query performance difference -- CPU time difference on two servers
Two SQL servers, server A & B, Hardware information as below:
Server A: Clustered. Two physical processors (4 cores). RAM 64GB, SQL Server max memory: 58GB.
Server B: Standalone. One physical processor (4 cores). RAM 16GB, SQL Server max memory: 10GB.
The two databases on A & B are identical (using backup & restore method), same query execution CPU time are different, it is slower on the cluster server with more CPU & Mmeory. I tried many times and all same result, I also tried run DBCC DROPCLEANBUFFERS
& DBCC FREEPROCCACHE before running the query.
When I run the query, on Server A (Slow one), CPU usage is at 20% ~30%. RAM usage is 14%. It is new set up environment so just me using it now.
When I run the query on Server B (Fast one), CPU usage is 40%, RAM usage is 85%.
Both two servers have SAN connected storage.
Query execution plan is exactly same on two serers.
Could someone give me some advise how to troubleshoot this problem? Any suggestion is appreciated a lot! Thanks a lot!

i just want to ask you
which sql version do you use？
have you ever tried xevent before？？
if you use the sql2k8 or latter you can try xevent out to find somgthing clues about your cpu time problem
i provide you the script，pls post your output in the xevent here so that we could judge what the head of the problem is

Strange cpu clock report DV7T 4100 CTO
just bought the DV7T 4100 CTO with a core i7-720qm processor (windows 7 64bit)... updated the bios to F.23. The strangest thing is that every single diagnostic software (CPU-z, Hardware Monitor, Intels T-monitor...etc...etc) reports my CPU as a 930Mhz on idle...although im sure its supposed to be 1600Mhz...
when i pump up prime 95... it reports 1750 Mhz ... why is my CPU beeing reported as half the speed than it should be? (having intels turbo thingy in consideration here...)Ok...here's the main problem...
the multiplier stays at x7 at idle (133 bus x 7 = 931Mhz)
when in turbo mode it goes up to x13 (checked it with TrotthleStop...x13 is the maximum supported multiplier) which brings the CPU to 1729Mhz...
Problem 2. the temperature coresponds to the factory CPU values...since at 931 Mhz it stays at 50-55 C (sometimes 60)
while at 1729Mhz it climbs up to 80 C... which is what most people would get if they had their real clocks...
it almost seems as if the Bus speed or the multiplier value is reported divided by 2... anyone know the benchmark CPU values of this (or a similar) model...so i can compare?
Thanks in advance... -
Question about CPU temperature
Hi, I have just built a new system with the following,
Motherboard - MSI 760GM-P23 (FX)
CPU FX 6300
and as this is my first venture over to the AMD side of PC's I have some questions about the CPU temp.
The image below is from my system under load, I'm told that the temp readings from AMD CPU's are not accurate below 40c?
The FX 6300 'package temp' cant be accurate with a low of 13c it's simply not possible in a room that's almost 20c.
What is TMPIN1? I hope that's not my actual CPU temp as 69c is way to high. and a Google search for TMPIN1 brings up lots of forum posts regarding MSI boards, Hence my post here.
TMPIN0 looks like the most likely sensor for CPU temp but I'm just not sure, so which one is it? and where is TMPIN1 reading it's info from?
Regards and many thanks, DaveWhat you see with HWINFO is the readings from two different sources. One is the reported temp by the AMD sensor, the other is the same temp but as reported and translated by the Fintek chip that MSI generally uses on their boards.
The differences in readings boils down to the digital signal to analog conversion by the two data suppliers, .i.e AMD sensor/Fintek chip.
If in doubt, always use the higher reported temp as the acceptable one. Quite frankly, I would think what the Fintek reports is probably close to what the real temps are. Common sense will dictate that what you see from the AMD sensor is virtually impossible unless you use liquid cooling.
Also remember that the software in use may differ in readings slightly.
The Fintek chip is reporting 2 CPU temps. I summise the higher as being the CPU core and the lower value as being a sensor in the vicinity of the CPU that MSI has added.
Comparing the info with your HW Monitor, I further believe that TMPIN1 is the same as the Fintek CPU higher temp. TMPIN2 is the one for the lower CPU value in HWINFO and TMPIN0 is probably your southbridge.
If you wish, run both these software packages at the same time and stress your machine in Prime95, Then you can monitor and figure out which ones are going up or down in unison. You may also find that the temps will be a lot closer then. -
Higher than normal cpu for fed (PunjectRx) process
I noticed on my 3850 that the CPU seems to have gone up overnight a fed days ago and has stayed there. Everything seems to be fine at the moment but I was just wondering what the process is that's causing it (google gives me nothing) and if I should be worried.
Running show processes cpu sorted gives me this:
Core 0: CPU utilization for five seconds: 15%; one minute: 18%; five minutes: 25%
Core 1: CPU utilization for five seconds: 97%; one minute: 45%; five minutes: 34%
Core 2: CPU utilization for five seconds: 15%; one minute: 51%; five minutes: 39%
Core 3: CPU utilization for five seconds: 10%; one minute: 20%; five minutes: 42%

10184 481691 20810070 573 5.20 5.37 6.54 34816 iosd
I asked for detailed info on the fed process and got the output below. As you'll notice, the high cpu value on the core doesn't always show up on the same core. What is that PunjectRx process that's responsible for the higher than normal value do?
Core 0: CPU utilization for five seconds: 20%; one minute: 27%; five minutes: 30%

Performance problem - Tablespace Free Space
Hi,
Version 10204
I am running the following statment in order to monitor tablespace free space.
There are some tablespaces that i am not interesting to monitor , and i also whant to be alert
only when less than 4 GB left in the tablespace.
I build the following statment.
Using the hint : /*+ NO_CPU_COSTING */ gave me the best performance but there are alot of time
that its took to this statment few minute to run befor it finished.
Could one help to improve its performance ?
Please note that it performe even less good when i used the RULE hint or not using hint at all.

- cpu costing is off (consider enabling it)Version 10204
I am running the following statment in order to monitor tablespace free space.
There are some tablespaces that i am not interesting to monitor , and i also whant to be alert
only when less than 4 GB left in the tablespace.
And just adding to Dan's reply, if you are on 10g as you mentioned, why not to use the built in Alert mechanism to monitor and get alerts about the tablespace usage using the GC or Database Console than creating a home grown solution like the one you have posted?

Sql Query is running fine in one database but running from long in other
Hi All,
Please advice me on below:
One query is running fine on 11gr2 database with having 2GB SGA and cost of the running query is 15, but the same query is running from long time in other database having same 2GB SGA.
Below is teh Query:

dbms_aqadm.grant_queue_privilege(''ALL'','''||:B1
||''','''||CDU.USER_NAME||''',true); end;', 'grant '||DECODE(:B2 ,

USER I/O Wait (Please help kind of stuck here from long time)
I have a delete statement running from more than 24 hrs now and the session info says its waiting on user I/O. There are no blocking sessions and its doing a full table scan of a table having around 500000 records. I dont understand what exactly its waiting on and how to check that and why it taking more than 24 hrs to FTS of 1 table? Here are some of the statistics:

Any help would be appreciable.
This deletes more that 60% of the records from this table so indexed should be out of question here, i think.

Actually Reega had a good point, not sure why he didn't go down the route.
You may want to find out what's that table/index your session is waiting from the value, something like
select owner||'.'||segment_name, segment_type
from dba_extents
where file_id=4 and (block_id between 116937 and 116937+66)This might be a long run query if you have many objects.
Actually the better view to query is v$session_wait instead of v$session.

COLLECTION ITERATOR PICKLER FETCH along with XMLSEQUENCEFROMXMLTYPE
Hi All,
We have Oracle database 10.2.0.4 on solaris 10.
I found some xml queries which are consuming CPU and memory highly, below is the execution plan for one of this xml sql.

),'6209870F57C254D6E04400306E4A78B0'))Seems due to
1.COLLECTION ITERATOR PICKLER FETCH along with XMLSEQUENCEFROMXMLTYPE which i think is due to usage of table( XMLSEQUENCE() )
2.Conversion taking place according to SYS_OP_C2C function as shown in Predicate Information.
3.Table is not using xmltype datatype to store XML
4.Wilcards have been used (/AlternateKey/@keyType)
Could anyone please help me in tuning this query as i know very less about XML DB
Including one more sql which also use to consume huge CPU and memory, these tables are also not hving any column with xmltype datatype.

Added one more sql..Looking at the second query, it too has a lot of bind variables... Can you find out the types and values of each BIND. Also, I'm suspcious about the use of XMLCONCAT.. Can you found out why the developer is using it..

I see that one of my queries from an application time is spending most of its time in the hash group by. I'm running Oracle 11g with a quarter rack exadata appliance. Is there a better way to run or design this table?

The query below has two tables and one view.
The query functions well but as soon as i add v_date and fin_year conditions, the query shows only matched results.That is the outer join is not showing the desired result.
I also want those values not in bill_ent and v_bm.
select mjcd,v_bm.amt,nvl(sum(gross_amt),0) from mjhd,bill_ent,v_bm
where mjcd>='2011'
-- and v_date>='01-MAR-07' and v_date<='29-FEB-08'
and mjcd=src_mjcd(+)
and mjcd=h_code(+)
-- and fin_year='20072008'
group by mjcd,v_bm.amt

MYHCheck out the SQL Reference for "OUTER JOIN". It says:
Oracle recommends that you use the FROM clause OUTER JOIN syntax rather than the
Oracle join operator. Outer join queries that use the Oracle join operator (+) are subject
to the following rules and restrictions
then a bunch of points there, and then:
If the WHERE clause contains a condition that compares a column from table B with a constant, then the (+) operator must be applied to the column so that Oracle returns the rows from table A for which it has generated nulls for this column. Otherwise Oracle returns only the results of a simple join.
I guess this is where you are stuck... -
Simple query but not using index..please help??
I do have this column indexed. Why my query is not using this index?
Any help .

Tune Query with Millions of Records
Hi everyone,
I've got an Oracle 11g tuning task set before me and I'm pretty novice when it comes to tuning.
The query itself is only about 10-15 lines of SQL, however, it's hitting four tables, one of them is 100 million records and one is 8 million. The other two are pretty small comparatively ( 6,000 and 300 records). The problem I am having is that the query actually needs to aggregate 3 million records.
I found an article about using the star_transformation_enabled = true parameter, then on the fact table I set all the foreign key to bitmaps and the dimensions have a standard primary key defined on the surrogate key. This strategy works but it still takes a long time for the query to crunch the 3 million records (takes about 30 minutes).
I know there's also the option of doing materialized views and using query re-write to take advantage of the MV, but my problem with that is that we're using OBIEE and we can't control how many different variations of these query's we see. So we would have to make a ton of MVs.
What are the best ways to tackle high volume queries like this from a system wide perspective?
Are there any benchmarks for what I should be seeing in terms of a 3 million record query? Is expecting under a minute even reasonable?
Any help would be appreciated!
Thanks!
