Dump and db size

How to check if a dump file is larger or lesser than the db size?
thx.

select sum(bytes/1024/1024) from dba_data_files will give the size of the db
compare with your dmp size
Whatever it is the dump will be much smaller the DB
i have 45 gb db but the dump will be of 2gb size

Hi Divyanshu,
I was away on to another project for configuring change control tool.
As mentioned earlier I don't have OS access.
But could able to download Thread Dumps via NWA as mentioned by David...., but couldn't able to open them.
Opened OOM.hprof file through MAT to check leak suspects etc. I could hardly understand as it is my first Java AS project ....here is bits and pieces from the dump analyzer tool.

Filename and path sizes and characters

I am failing to load 4000+ tracks to my Ipod from my XP machine using Itunes 7.50.0.20. This is an Ipod Clickwheel 20GB. I want to load 17.86GB in the now empty Ipod. However it gets so far then stops saying there is not enough space.
I wonder if am I getting the wrong message?
Some of my tracks have very long filenames/paths e.g 124 charactere filenames and 213 character paths. I also have some filenames with " (double quote) in.
Could this be the reason?
If so what characters must I avoid and what size should the filename and paths be limited to?

Filenames and paths are irrelevant. They are renamed on the iPod anyway.
20 GB is not really 20. It is a rounded number all HD manufacturers use. Plus you lose some space due to formatting and the iPod software. There is also meta data for the songs which takes some space.

Photoshop CC 2014 UI Menu Text And Icon Size?

so i really like that adobe has added the "experimental" option to increase the ui menu text and icon size in photoshop cc 2014, it was almost unreadable on my 2560 x 1440 27" monitor with photoshop cs4 and illustrator cs4, but the lone 200% setting is too big... seems that 125%, 150%, or maybe even 175% would be much better solutions. in fact, for reasons i can't quite understand, the ui text and icon size in illustrator cc 2014 is spot on, absolutely perfect on my monitor, even tho there is no option for increased ui size as far as i can tell, it was spot on the moment i installed and launched it.
in short, the photoshop cs4 and illustrator cs4 user interfaces were identical in size as far as i could tell, and far too small on my 2560 x 1440 27" monitor. in terms of cc 2014, the illustrator ui is perfect out of the box on my monitor, considerably larger than illustrator cs4, while the photoshop cc 2014 ui is identical to cs4, tiny, but can be enlarged 200% which makes the ui too big. why couldn't/didn't adobe just make the photoshop cc 2014 base ui the exact same size as the illustrator cc 2014 ui? it would have been perfect (for my monitor size).

thanks... just wish illustrator cc 2014 wasn't so perfect in terms of ui size, i mean it's just great and, consequently, makes it seem as if the ball was dropped with photoshop cc 2014... i mean how can one be spot on while the other be so far off?

Drag and Drop and Image Size

I need to be able to drag and drop images but I need them to be a certain size when I drag them out of an Aperture project. For various reasons, I don't want to use the export function. Only drag and drop will be efficient for the workflow that I"m planning. Problem is, the pixel dimension is not wide enough when I test it by pulling an image on to the desktop.
My ultimate goal is drag them, sized and ready to go, and drop them onto a web browser upload page. I don't want to fumble with the extra steps of exporting them to another folder on the desktop and then upload the images from that folder to the browser.
So does anybody know how or if it's possible to control the drag and drop SIZE /DIMENSION of an image?

The drag and drop size is determined by your preview settings. What actually gets "dragged & dropped" is the preview, not the master file. You can control the quality and size of the preview in the Aperture preferences.

I have many photos with file extension of .PDD and that Photo Deluxe 4 no longer will operate in Win 7. How can I open? Next in Elements 11, how do I load and print different pictures and different sizes options on the same page?

Multiple Convert/Dump and Load tasks in a single SSIS package?

I'd appreciate some input. We have a single data file that has about 1,000,000 rows of data spanning 28 time periods in the columns across each row. The file is too large to import at one time, and so we have created 9 different transformation files to pull subsets of the timeperiods using MVAL. The end user does not want to have to break apart the file and/or schedule 9 separate imports to bring this file in each time. So, I've attempted to create a single SSIS package that runs each of the 9 required component imports, but I'm running into the following error any time that I try to run more than one import at once:
An error occurred while running a packageException of type 'System.OutOfMemoryException' was thrown.
I've tried using a ForEach loop to simply loop through each of the transformation files and run an import for each transformation file it finds. But, I understand that SSIS doesn't release memory until the end of the ForEach loop, which would explain an out of memory issue. I then broke it out and specified 9 distinct Convert task and 9 distinct Dump and Load tasks in the package with an order of Convert 1 --> Dump and Load 1 --> Convert 2 --> Dump and Load 2, etc. This results in the same out of memory issue any time I enable it to run more than 1 convert/dump & load task in the package - they are not running simultaneously, but rather sequentially. I don't understand this. In looking at the logs, it looks like it's creating the temp files for the first import and adding them into BPC, and then creating the temp files for the second import but then fails prior to the second load. This will work for a smaller data file, but shouldn't the memory be released after the task and allow subsequent tasks to complete? Any recommendations on how to address this and automate this load?

Quick update - I created unique ssis packages for the distinct imports and called those packages from within the initial package that is kicked off through Data Manager, and I ran into the same out of memory issue. Any ideas, suggestions, or help would be greatly appreciated.
Thanks!

I just updated my iTunes and I do not like the newer version.....can I go back to the earlier version?? This new version does not have the iTunes DJ nor does is show at the bottom as in the earlier version how many songs and the size of my library.

To do this in iMovie 11. use the SHARE menu. Share your project using the Share menu and choose Export Using QuickTime.
In the Dialog box that comes up, choose Sound to AIFF, or one of the other sound options. This will create a file that you can drag into iTubes.

Blue screen hard disk dump AND memory dump

I sent my toshiba satellite a215-s4767 to the repair depot for a screen replacement and since i got it back i have had 2 blue screen memory dumps and 1 hard disk dump blue screen(that was last night). I got it back on christmas eve so ive had it back for 2 weeks.

Please take a look at this document USB 3.0 Blue Screen Document. Verify your USB 3.0 chipset is the same as described in the document and if it is the same download the fix from Intel.

I am using your software: CS^ InDesign Suite on a PC using a Windows 7 operating system. Due to eyesight issues, I need to have the menu bars of programs in easy-to-read font and picture size. Specifically, the menu bar

Hi,
I am using your software: CS6 InDesign Suiteon a PC using a Windows 7 operating system.
Due to eyesight issues, I need to have the menu bars of programs in easy-to-read font and picture size. Specifically, the menu bar across the top (File, Edit, View, etc.), and the menu bar on the left side with the graphic depiction of options.
In earlier versions of Windows (e.g. XP), whenever I changed the screen resolution on my computer to a lesser resolution in order to show the link icons on my desktop in a larger, more readable size, all the software programs, including yours, appeared on my screen with the menu bars in the larger font size that I needed.
However, in Windows 7, this is not the case. Even though I have selected the lowest resolution, making the icons on my desktop extremely large, I cannot read the options across the top menu bar of your program, nor the pull-down menu items that they contain. I cannot see the graphic depictions of options on the left side of the screen. They are all too small. How can I make your program increase the size?

CS6 is not high-DPI compatible/ enabled and that can't be changed. If you cannot6 make it work with your operating system means, then short of joining Creative Cloud and using newer versions there is nothing you can do.

How do I change the font and graphic size when using Firefox

I have recently switched from Windows to Mac. When resizing the window in Mac the font and graphic size do not follow -- they stay the same size and only more "white space" is created by increasing the window size. How do I get the graphics and fonts to adapt to the new window size or at least make the whole image bigger. I am using Firefox 3.6.12 and Mac OS10.6.5. Thanks for the help.

Tablespaces and block size in Data Warehouse

We are preparing to implement Data Warehouse on Oracle 11g R2 and currently I am trying to set up some storage strategy - unfortunately I have very little experience with that. The question is what are general advices in such considerations according table spaces and block size? I made some research and it is hard to find some clear answer, there are resources advising that block size is not important and can be left small (8 KB), others state that it is crucial and should be the biggest possible (64KB). The other thing is what part of data should be placed where? Many resources state that keeping indexes apart from its data is a myth and a bad practice as it may lead to decrease of performance, others say that although there is no performance benefit, index table spaces do not need to be backed up and thats why it should be split. The next idea is to have separate table spaces for big tables, small tables, tables accessed frequently and infrequently. How should I organize partitions in terms of table spaces? Is it a good idea to have "old" data (read only) partitions on separate table spaces?
Any help highly appreciated and thank you in advance.

The question is what are general advices in such considerations according table spaces and block size? If you need to ask about block sizes, use the default (i.e. 8KB).
I made some research and it is hard to find some clear answer, But if you get contradictory advice from this forum, how would you decide which bits to follow ?
A couple of sensible guidelines when researching on the internet - look for material that is datestamped with recent dates (last couple of years), or references recent - or at least relevant - versions of Oracle. Give preference to material that explains WHY an idea might be relevant, give greater preference to material that DEMONSTRATES why an idea might be relevant. Check that any explanations and demonstrations are relevant to your planned setup.

Is it a good idea to have "old" data (read only) partitions on separate table spaces?
It is often convenient, and sometimes very important, to separate data into different tablespaces based on some aspect of functionality. The performance thing was mooted (badly) in an era when discs were small and (disk) partitions were hard; but all your other examples of why to split are potentially valid for administrative. Big/Small, table/index, old/new, read-only/read-write, fact/dimension etc.
For data warehouses a fairly common practice is to identify some sort of aging pattern for the data, and try to pick a boundary that allows you to partition data so that a large fraction of the data can eventually be made read-only: using tablespaces to mark time-boundaries can be a great convenience - note that the tablespace boundary need not match the partition boudary - e.g. daily partitions in a monthly tablespace. If you take this type of approach, you might have a "working" tablespace for recent data, and then copy the older data to "time-specific" tablespace, packing it and making it readonly as you do so.
Tablespaces are (broadly speaking) about strategy, not performance. (Temporary tablespaces / tablespace groups are probably the exception to this thought.)

What is the best Practice to improve MDIS performance in setting up file aggregation and chunk size

Hello Experts,
in our project we have planned to do some parameter change to improve the MDIS performance and want to know the best practice in setting up file aggregation and chunk size when we importing large numbers of small files(one file contains one record and each file size would be 2 to 3KB) through automatic import process,
below is the current setting in production:-
Chunk Size=2000
No. Of Chunks Processed In Parallel=40
file aggregation-5
Records Per Minute processed-37
and we made the below setting in Development system:-
Chunk Size=70000
No. Of Chunks Processed In Parallel=40
file aggregation-25
Records Per Minute processed-111
after making the above changes import process improved but we want to get expert opinion making these changes in production because there is huge number different between what is there in prod and what change we made in Dev.
thanks in advance,
Regards
Ajay

Hi Ajay,
The SAP default values are as below
Chunk Size=50000
No of Chunks processed in parallel = 5
File aggregation: Depends largely on the data , if you have one or 2 records being sent at a time then it is better to cluster them together and send it at one shot , instead of sending the one record at a time.
Records per minute Processed - Same as above
