Unusual IOPS MAPS Result in Logarithmic Notation

The performance metrics report for disk utilization conducted for 72 consecutive hours on a Server 2008 R2 SP1 with a 64TB RAID-6 array being used for a video security camera deployment (110 video cameras) shows the following:
Average Disk IOPS 7.32026E+13
Maximum Disk IOPS 3.07451E+16
95th Percentile Disk IOPS 4733.77
Avg Disk Writes/sec 7.32015I+13
Max Disk Writes/sec 3.07446E+16
95th Percentile Disk 4715.51
There are performance issues with the cameras as currently provisioned...CPU and RAM are within normal limits. Network bandwidth is not a problem.
What does the logarithmic notation on some of these results mean? How should I interpret those numbers? Does it mean that the disk writing load of the cameras is exceeding the IOPS capacity of the disk array
to write to disk? Or alternatively is this just an anomalous result which indicates I should repeat the MAPS report? The server is capable of accommodating 16TB of additional disks in the array. Is it possible that by adding those additional disks to bring
it up to 80TB that the camera writing load might be normalized?
Thanks,
Scott

These are very odd results. MAP is getting the performance from these performance counters in Windows:
PhysicalDisk > Disk Transfers/sec > _Total
PhysicalDisk > Disk Reads/sec > _Total
PhysicalDisk > Disk Writes/sec > _Total
Try looking at these counters in perf mon on the machine in question. Does it also show really large numbers?

Result in scientific notation

Hi,
We migrated an instance from 7.3 to 7.6 x64 (no unicode) and I get an expression result in scientific notation.
How can I make the notation use decimal? I cannot find anything in the documentation.

Where to see mapping result in PI 7.1?

Hi all,
In PI 7.1 sxi_monitor and RWB, we only see see the incoming message in PI, but I haven't found any place where I can see the resulted message of the mapping, or the outgoing message in PI. Anybody knows how to see the outgoing message in PI 7.1?
Thanks

Hi VJ,
really? Can you please tell me the path in sxmb_adm to configure the parameters? can you please post the screenshot of the corresponding config screen?
We have very strict (and strange) security policy, and I have no access to the sxmb_adm, I need to tell the basis team what exactly to change in sxmb_adm (even I have no access to try it).
Thanks

but client doesnot want <![CDATA] and ]] at the end. Basically client doesn't want CDATA tag as it is throwing error wihile collecting message in Web Service.
Please help!!

Hi,
You remove CDATA from xsl program which you are using in mapping so that it will come in output. Because CDATA we will use in DTD only, not required in XSL program.

Problem mapping results with FM F4UT_RESULTS_MAP

Hi experts,
I have modified S_MAT1 search help adding a new tab to the search help. In particular, this new tab searchs by material long description.
The problem is that when I call to the function module F4UT_RESULTS_MAP my results are mixed up. Lines of material long text are sorted in internal table, so I expected that this function module maps from I_SEL to RECORD_TAB table.
How can I solved that?
CALL FUNCTION 'F4UT_RESULTS_MAP'
        TABLES
          shlp_tab          = shlp_tab
          record_tab        = record_tab
          source_tab        = i_sel
        CHANGING
          shlp              = shlp
          callcontrol       = callcontrol
        EXCEPTIONS
          illegal_structure = 1
          OTHERS            = 2.
Previously, I calculate the hit list using SELECT event from callcontrol-step, and saving values to I_SEL internal table.
Any help would be apreciated.
Lots of thanks,
Javier

Owb mapping result in excel sheet

hi ,
can anyone help me to know how i can get owb mapping running status & result in excel sheet.
I have completely forget it.
kindly help.

Hi,
You can view the status by qurying wb_rt_audit_map_runs from any SQL client.
From there your can copy the output to excel.
Otherwise you can use OWB repository browser to view the mapping running status report.

Map result set elements to XML

Hi,
Iam retrieving fields from data base in to a result set.Iam creating an xml file using the result set fields by passing the column names as xml tags.the xml file is generated and working fine.But i wanted to add custom tags instead of column names in my xml files.
is there any way to map the fields with my custom tag names?
Thanks,
Ravi

I know that the site below does not cover exactly what you want but you can customize the code snippets to your needs. All you have to do is to devise a suitable algorithm to avoid the repetition of sibling elements having the same text. With regard to this requirement I advise you to order the records in the ResultSet before processing them because it makes the comparison of the records (which is unavoidable to find the repetitive values) much easier.

Spotlight doesn't show Web, Wikipedia, Maps results. Handoff breaks Mail.

Hi everyone,
I just upgraded my rMBP (2014) to 10.10. The features I was looking forward to most are currently not working for me. Maybe you can help or report similar issues.
1) When using spotlight, it does not show any results from the web, no Bing search results, no Wikipedia entries. It also doesn't show any places via the maps application. Notably, the spotlight settings panel does not show an option to search wikipedia or maps, it does, however, have an entry for bing web search results. I tried unchecking everything except bing results, but still couldn't get spotlight to show anything. Is this a known problem or is something wrong at my end?
2) I started composing an email on my IPhone (6, running 8.0.2) and was happy to see the handoff icon appear in the dock. Clicking it, however, resulted in Mail opening a new message composition window which first started to load (forever) before eventually crashing (Application stopped responding). This issue can be replicated (in fact I have run into it every single time I tried).
Having seen 6(?) beta versions and still having major, feature breaking bugs in the final product is quite disappointing. The argument "hey, it's free, what do you expect?" doesn't count.
Your suggestions are greatly appreciated.
Chris

Most probably web/wikipedia searches in spotlight are only available in select countries. Doesn't work here in India.

Select Query resulting in Scientific Notation

Hello all,
I am running a Select query through a batch file that extracts data from an Oracle database. Several of the fields that I am extracting from contain numbers that are up to 38 digits long. When I extract the data, it converts the numbers into scientific notation and it is important for me to have the entire field. Is there something I can change to my query that will pull the data in its entire form? This is what I'm running now:
select * FROM ML.APPT where APPTDATE >= to_date('01/1/2010','mm/dd/yyyy'
I apologize in advance if this has been answered already.
Thanks!

>
When the extractor finishes, it returns the data into a flat file.
don't quite understand the TO_CHAR function. Does this function mean I need to say something like this: select "TO_CHAR('column name', 99999999999999999999999999999999999999" FROM ML.APPT where APPTDATE >= to_date('01/1/2010','mm/dd/yyyy')
>
Yes- if the tool you use to extract the data (your 'extractor') is converting the numeric data to a string then it is responsible for creating the string in the proper format. If the number is an integer that can have as many digits as you have '9's in your sample format string then that is what you need to do.
Here is how sql*plus (Oracle's tool) will display the data using default settings
SQL> select 12345678901234567890123456789012345678 no_format,
2 to_char(12345678901234567890123456789012345678, '99999999999999999999999999
999999999999') with_format
3 from dual;
NO_FORMAT WITH_FORMAT
1.2346E+37 12345678901234567890123456789012345678
SQL>
----- TOAD will display something similiar but the default uses more decimal digits in the scientific notation data
NO_FORMAT,WITH_FORMAT
1.23456789012346E37, 12345678901234567890123456789012345678You can either format the numeric data in the query using TO_CHAR or the 'extractor' can do it when it converts the data to a string.

Process Flow Execution of Mapping results in ORA-01403: no data found

Hi,
When the Mapping is run standalone, it runs fine, but when run through a Process Flow, it generates ORA-01403 on a FILTER within the Mapping.
What should be the debug steps. The RTE_ROWKEY is mentioned as 0 and does not help.
OWB Version is 9.2.0.2.8
- Jojo

So, when I submit the form, the Apex error I see is:
ORA-01403: no data found
Error Unable to process row of table fRQ (the debug is also posted in mail earlier)
Thanks

View Mapping Result between two Interface Mappings in ccBPM

Hello,
I've got a ccBPM which does two interface mappings. The second one fails. When I redo the steps manually in the Interface Mapping test mode everything works fine. Anyway, I want to get the message from the failed BPM that got out of the first interface mapping, which worked fine in the BPM as well, before entering the second.
Where can I get that message? In Monitoring I can only find messages that got sent.
Thanks for you help!
Regards,
Dirk

Hi,
Please check in Runtime Workbench.
Go to Adapter Engine --> Component Monitoring
Now select your Adapter.
Use Filter and below you will find message ids.
select one and you can see the audit log..where your appln fails.
You can also use SXMB_MONI.
Select the message giving error and in that goto outbound tab..click on link...select view details image button...select the component with error and go to container tab of it....there you will find trace entry....where log of your error will be stored..
Hope it helps.
Best Of Luck

Unusually effective Map app in iPod Touch

"Any sufficiently advanced technology is indistinguishable from magic."
My first Gen iPod touch seems to know where I am when I'm using the Maps application even if I'm not connected to any wifi network. This happened to me in San Francisco once but I chalked it up to the prevalence of WiFi network there. But recently I was driving around Oxnard (not a place with great free and open wifi coverage) following directions on the map app I had set up ahead of time, and I found that the blue dot showing my position changed as I was driving around, showing my current location in real time.
How the heck does this happen? The thing doesn't have GPS AFAIK.

You might have come into an area that allowed your iPod to update your position. (It happens.)
No iPod has a built in GPS that I am aware of. That's an iPhone feature, because they have the 3G thing.

'Mapped instrument' for percussion notation not mapping

I followed instructions to create a "mapped instrument" corresponding to drum samples from VSL. As I understand it, one assigns both a note head and an instrument group to each MIDI note. So, for example, my sampler instrument has three different kick drum sounds, coming from three different MIDI notes. I've assigned them all the "Drum Group" called "kick drum", and I've set the "Pos" field to 'down-arrow' 3.5, with the understanding that this means three lines below the top line, with an additional .5 to reach the bottom space on a clef.
Why aren't the MIDI notes that I've associated with the kick-drum settings, in the mapped instrument, appearing as they should on the score? When I change the MIDI-note/pitch in the piano roll, from a note associated with pos down-arrow 2 to pos down-arrow 4, I expect the note to go down two staff lines, but it doesn't. I can't make rhyme or reason of the connection between that track and the score it produces...?
Thanks,
Ben

In my opinion the best out there is BFD- I own it, and it sounds great. For Latin style percussion and other things like that you would need to buy the expansion kit, just to give you a heads up. It's designed to be a very good and very expandable system, with you having the ability to add sounds depending on what you actually will use, percussion, Jazz, etc.
Right now you can buy BFD 1.5 for $199, maybe cheaper somewhere, and upgrade to BFD 2- a major upgrade- for $199. That way you can sort of try it out and see if you like the sounds before committing all the way.
Just a thought. Go on their website and you can listen to it in action a little bit. A warning, though: right now BFD and Logic can't used BFD's multiple outputs. It's being worked on. You can only get the stereo out, not each piece of a kit onto a separate track, which is a major reason I got BFD.

Unusually High MAPE Values

Posting it again for anyone to give you some inputs.
We ran forecast on a selection ID that has all Product-Customer combinations using Auto Model 56 in the bakground on Prod-cust level. The system has proposed a strategies like constant, croston, seasonal and so on ..which is fine.
We have set up a limit of 80 for the Error Metric MAPE in the Diagnosis group. If I am not wrong, MAPE is a percentage value and 80 should mean 80%. But after the forcast run using 56, the system generated abnormally high MAPE values, for example MAPE values obtained are in 10's of thousands like 2,956,009.830 and even 10,000,000.000 . These are no where close to our limit 80. MAPE is the average of absolute percentage differences between Acutals and Expost forecast. So how could system generated MAPE be so high for all the combinations . Are we supposed to read it differently, because i thought auto model though may not propose the best fit model parameters, but atleast not give us a forecast which has such high MAPE values. I was expecting MAPE within 100 or worst case 200, 300 but not thousands and millions..
Am I missing something ? Please help - Susan

Hello Susan
You could use the MAPE-A. You have to implemnt it on your own in a badi.
The MAPE-A ist a value between 0-2.
Hope thats helps you.

Calculator: removing scientific notation in results?

This seems like it must be a bug or a corrupted app, but I'd just like to confirm: with the calculator in "basic" mode, dividing two numbers which only have one significant digit returns a result like so: 1/3000 = 0.000333 (the setting for decimal places seems to be irrelevant).
However, changing either number to have more than one significant digit returns the result in scientific notation, like so: 1/3100 = 3.225806e-04.
Can anyone else duplicate this or help me correct it? It's obnoxious to have to keep adjusting the numbers. And yes, I realize that means my math skills suck. Thanks in advance.

Bumpty-bump. Can anyone at least confirm or deny? TIA.
