Size of data processed by the engine

The Power Query specification here describes the "Size of data processed by
the Engine" as:
"Limited to available virtual memory (for 64-bit version) or about 1GB for 32-bit version, if data cannot be fully streamed, such as when sorting the data set locally before filling it"
What is meant by the part where it says "if data cannot be fully streamed, such as when sorting the data set locally before filling it"?
Is it saying that the limits don't apply when sorting? Is it applicable to 32-bit only?
Thanks

Power Query will try to tell the server to do the transformations on their side if they can which means that Power Query does not need to store all of the data locally. In certain cases this is not possible, so Power Query has to download the data
locally before doing the transformation, which takes up memory.
In this case, if we have to do the sort locally (because the user has buffered the result or because the data source we are using cannot be streamed), then the 32-bit version of Power Query can use up to around 1 GB of memory while the 64-bit version of
Power Query can use as much virtual memory that's available on the system.
I hope that helps.
Thanks.

Size of data stored in the database

How can i find the total amount of space data occupies in the database?

Hi,
Check the dba_extents view which give u all the allocated extents and their sizes for all the objects in the database.
Good luck,

Listing File, path, sizes and dates

Hi all
Case: I have 6 machines on one network (some with 2 drives), another on another network (connected by vpn) and 3 external drives.
These all have accumulated stuff, some repeated as I've upgraded and re-purposed machines but left directories behind as a safeguard.
I need to rationalise the space and develop a more systematic approach to backup and archiving.
My first step is do an inventory of what's where and my natural approach is work with a data base of file name, path, size, created date and last modified to allow me to do some maths on archiving to dvd.
Using find as follows
find [Start Somewhere Directory] -print > [workspace path]/TestOutput.txt
gives me a nice list of file name I can parse out in a database
But I don't get size and dates.
Adding -ls produces that info but creates header lines for parent directories and adds permissions, node and other info I don't need.
I got to here
find [Start Somewhere Directory] -type df -exec ls -lshk {} \; -print > [workspace path]/TestOutput.txt
but still has the hierarchical output rather than flat paths.
Am I doing this all the hard way ? Is there a tool that returns just what I'm looking for ?
Or what command will allow me to take just the relevant columns form ls to the print parameter ?
Or can I extend find to add the size and date info to the output ?
Kind Regards
Eric

I just so happened to have done something similar before!
It relies on mdls so isn't exactly speedy, but produces a full path, size, modification date, modification time, creation date and creation time as a comma separated list. mdls is not exactly predictable as to which order you get its output, so basically you have to try first without any editing.
Anyway, here it is:
sudo find ~/testfolder -type f \! -name ".*" -exec echo 'mdls -name kMDItemFSSize -name kMDItemFSCreationDate -name kMDItemFSContentChangeDate "{}" | tr "\n" "," | sed "s%^$/.*$ .*ChangeDate = $....-..-..$ $.*$ .CreationDate.= $....-..-..$ $.*$ ...00,.FSSize.= $.*$,$%\"\1\",\6,\2,\3,\4,\5%"' \; | shI'm sure it could be improved!
You could also do it with AppleScript, since that can access the creation date easily.

Lock-In Amplifier and offline data processing

Hi everyone,
I've been successfully using the Lock-In Amplifier to do live data processing. The processed Lock-In outputs and the frequency values are then saved. Recently it has turned out that the real acquisition capabilities needed mean that online processing is not possibe. (As 4 channels are being simultaneously sampled each at 4Mhz and acquiring for several seconds.) I have built the Lock-In Amplifier into an offline processing VI where I strip out the arrays for Channel 0 (Signal) and Channel 1 (Reference) and send chunks of data to the Lock-In. I wanted to check that the Lock-In doesn't have any problems working offline? Are there any other things I need to know for offline processing?
Many thanks

Hi,
I've not personally had the change to use Lock In Amplifiers with our hardware yet, but from searching through the LabVIEW developer zone I came across this example VI, I hope it's some help to you: http://zone.ni.com/devzone/cda/epd/p/id/4532

I get an error message saying "system overload, the audio engine was not able to process all the required data in time (10011)

i get an error message saying "system overload, the audio engine was not able to process all the required data in time (10011)

The thing is, that error message has been appearing when playing/recording a track that was running perfectly a few minutes ago and nothing has changed!
That can mean, that your project is too ambitious for your Mac. Are you using many complicated automations on that track?
4GB memory is not much, when doing audio processing. GarageBand will need all memory it can get, or will be forced to continually swap pages to your disk, to free RAM, and that can cause this error.
When this error occurs, it is best to restart the computer. This will free your RAM. Close all other applications that are competing for memory, i.e. other multimedia applications, and Safari.
Also, make sure, that you have plenty of free disk space. Don't let the free disk space drop below 20G.
Where is your project located? On an external drive or your internal drive? If it is on an external drive, connect this drive directly, not daisy-chained, or move the project to your internal drive.
I got up to eat, came back and tried to continue but GarageBand shuts down and displays that message every time I try to run the song. I've also recently run songs with several more tracks than this one and they worked perfectly. Any tips?
Are your other projects, that worked perfectly, still working?

Errors in the high-level relational engine. A connection could not be made to the data source with the DataSourceID of '

When I deploy the cube which is sitting on my PC (local) the following 4 errors come up:
Error 1 The datasource , 'AdventureWorksDW', contains an ImpersonationMode that that is not supported for processing operations.  0 0
Error 2 Errors in the high-level relational engine. A connection could not be made to the data source with the DataSourceID of 'Adventure Works DW', Name of 'AdventureWorksDW'.  0 0
Error 3 Errors in the OLAP storage engine: An error occurred while the dimension, with the ID of 'Customer', Name of 'Customer' was being processed.  0 0
Error 4 Errors in the OLAP storage engine: An error occurred while the 'Customer Alternate Key' attribute of the 'Customer' dimension from the 'Analysis Services Tutorial' database was being processed.  0 0

Sorry hit the wrong button there. That is not entire solution and setting it to default would work when using a single box and not in a distributed application solution. If you are creating the analysis database manually or using the wizard then you can
set the impersonation to your heart content as long as the right permission has been set on the analysis server.
In my case I was using MS Project Server 2010 to create the database in the OLAP configuration section. The situation is that the underlying build script has been configured to use the default setting which is the SQL Service account and this account does
not have permission in Project Server I believe.
Changing the account to match the Project service account allowed for a successful build \ creation of the database. My verdict is that this is a bug in Project Server because it needs to include the option to choose impersonation when creating the Database
this way it will not use the default which led to my error in the first place. I do not think there is a one fix for all in relations to this problem it is an environment by environment issue and should be resolved as such. But the idea around fixing it is
if you are using the SQL Analysis server service account as the account creating the database and cubes then default or service account is fine. If you are using a custom account then set that custom account in the impersonation details after you have granted
it SQL analysis administrator role. You can remove that role after the DB is created and harden it by creating a role with administrative permissions.
Hope this helps.

Maximum package size for data packages was exceeded and Process terminated

Hello Guru,
When i am execute the process chain i got this message Maximum package size for data packages was exceeded and Process terminated,any body help to me in this case how can i proceed.
Thanks & Regards,
Suresh.

Hi,
When the load is not getiing processed due to huge volume of data, or more number of records per data packet, Please try the below option.
1) Reduce the IDOC size to 8000 and number of data packets per IDOC as 10. This can be done in info package settings.
2) Run the load only to PSA.
3) Once the load is succesfull , then push the data to targets.
In this way you can overcome this issue.
You can also try RSCUSTV* where * is an integer to change data load settings.
Change Datapackage size for extraction, use Transaction RSCUSTV6.
Change Datapackage size when upload from an R/3 system, set this value in R/3 Customizing (SBIW -> General settings -> Control parameters for data transfer).
IN R/3, T-Code SBIW --> Genaral settings --> Maintain Control Parameters for Data Transfer (source system specific)
Hope this helps.

What's the maximum size of data a coherence cluster can hold?

What's the maximum size of data a coherence cluster can hold before it starts noticing a degradation in performance?
Assume a partitioned topology is used with only one backup for each partition.

Hi,
Coherence partitioned cache is designed for linear scalability and it does it quite well. I don't see any reasons of performance degrations with increase in data size given, you have enough cores and memory for processing the requests and managing the data.

Wat is the maximu size of data XI can handle

HI,
I would like to know wat file size XI system can handle at one time. What size of data can XI handle.
Please reply me as soon as possible.
Thanks in advance.
Chirag

Gohil,
This all depends upon your hardware and sizing the XI box. Also it depends on how complex your mapping and whether you are using any BPM inside the scenario or not. I have come across where XI is used just to move the file of 1GB also.
If your file adapter or XI is going down with this file then I would suggest to read chunks of data into XI and process further.

Map Reporting Application - Push Data process creating 40 MB size files

Hi all,
We have 6 map reporting applications in our Planning app. 2 of them push data to a BSO cube, 4 of them push data to an ASO cube. For the ASO cube ones, the process creates files that are about 40 MB size in the Essbase server under C:\Windows\Temp folder. The files are encrypted. I can't tell what the content is... The only reason I think the push data process creates these files is because of the date stamp of the files. They match the push data process.
Have you seen this? Is there a way to stop it? Since we run this process every hour and the files are pretty big, we run out of disk space pretty quickly. Our work around is to purge the files or delete them, but it would be ideal if we can stop this.
Any help?
Thanks,
Mehmet

Hi Mehmet,
Which version of planning are you using?

Data processing in multiple caches in the same node

we are using a partitioned cache to load data ( multiple types of data) in multiple named caches. In one partition, we plan to have all related data and we have got this using key association.
Now I want to do processing with in that node and do some reconciliation of the data from various sources. We tried entry processor, but we want to consolidate all data from multiple named caches in the node. In a very naive form, I am thinking each named cache as a table and i am looking at ways to have a processor that will do some some processing on the related data.
I see we could use a combination of Invocable object, Invocation service and entry processors, but I am unable to implement it successfully.
Can you please point me to any reference implementation where I can do processing at the data node without transfering data back to client.
Also any reference implementation of Map reduce (at the server side) in coherence would be helpful.
Regards
Ganesan

Hi Ganesan
A common approach to perform processing in the grid is to execute background threads in response to backing map listener events. The processing is co-located with data because the listener will be called in the JVM that owns the data. The thread can then make Coherence calls to access caches just like any other Coherence client.
The Coherence Incbutor has numerous examples of this at http://coherence.oracle.com/display/INCUBATOR/Home. The Incubator Common component includes an event processing package that simplifies the handling of events. See the messaging pattern for an example: Message.java and MessageEventManager.java
I am not sure I answered your question but I hope the information helps.

How to extract the size and date from a given file

Hi,
I want to extract the size and date of a file (it can be either a video, audio or text file) that the user points to the location of. But I am not sure how. Does Java have an api that can do this? If not is there some other way of doing this? Can anyone help? Thanks in advance.

Have a look at java.io.File, specifically
public long lastModified()
This format returned (I find) is nasty, so then use java.util.Date (or java.sql.Date, look the same on the surface to me) to format it.
Cheers,

Also, is it a 64 bit machine? check the target platform of the application and set it accordingly.
Few things to try
- Check if the reports exist and are accessible by the application (permissions, filepath,)
- Do not publish the report using the publish option, just as a test copy them manually.
See if this helps,
