Importing too much?
Hi,
Just a general question about the "import" statement.
Does the amount of classes imported into a java file, or the number of individual import statements, influence the size of the generated class file?
For example, would a file that included the statement "import java.swing.*" make a bigger or smaller or equal-sized class file, compared to one that included individual import statements for each Swing class that was actually used?
What sort of overhead is there for an import statement?
Ben
No, the class file will stay the same regardless. It doesn't matter if you import a single class or the whole package, there will be no effect on the class file. It can however slow down the time taken to compile it into a class file if you import a whole package instead. Still, even that isn't usually noticable.

Imported too much -- how to fix
I apologize for posting what must be a constant newbie question but I was not able to find the answer to this even after an hour of diligent searching... which is what does emptying the iPhoto trash really do?
When starting up iPhoto for the first time, we accidentally imported too much. Instead of just importing from the copied-images-from-old-computer folder, my wife imported from the whole HD and got things like icon images from various applications into the iphoto pool. How the heck do we get those out of iphoto without deleting them from the HD?
If I understand how things work, putting an image into trash and then emptying the trash will also delete it from the HD. We certainly don't want to do this to app-related images.

Message was edited by: rwexelblatWelcome to the Apple Discussions. When deleting don't delete more than about 100 photos at a time. iPhoto has problems with trying to delete large number of photos in one shot.
Do you still that the *+copied-images-from-old-computer folder+* ? If you do just delete the current iPhoto Library from the Pictures folder, create a new library and reimport just that folder. -

KhanThe import is in post processing. It digs through all the documents and adapts them to the new client. Most of the tables in the application area have a "MANDT" (= client) field which needs to be changed. Depending of the size of the client this can take a huge amount of time.
You can try to improve the speed by updating the table statistics for table D010INC.

HEHello Mohan,
The DBTABLOG table does get large, the best is to switch off logging. If that's not possible, increase the frequency of your delete job, also explore one more alternative have a look at the archival object: BC_DBLOGS, you could archive old records (in accordance with your customer's data retention policies) to reduce the size of the table.
Also, have a look at the following notes, they will advise you on how to improve the performance of your delete job:
Note 531923 - Audit Trail: Indexes on table DBTABLOG
Note 579980 - Table logs: Performance during access to DBTABLOG

Hi all
I'm quite new to database administration.my problem is that i'm trying to import dump file but one of the table taking too much time to import .
Description::
1 Export taken from source database which is in oracle 8i character set is WE8ISO8859P1
2 I am taking import in 10 g with character set utf 8 and national character set is also same.
3 dump file is about 1.5 gb.
4 I got error like value is too large for column so in target db which is in utf 8 i convert all coloumn from varchar2 to char.
5 while taking a import some table get import very fast bt at perticular table it get very slow
please help me thanks in advance.......Hello,
4 I got error like value is too large for column so in target db which is in utf 8 i convert all coloumn from varchar2 to char.
5 while taking a import some table get import very fast bt at perticular table it get very slow For the point *4* it's typically due to the CHARACTER SET conversion.
You export data in WE8ISO8859P1 and import in UTF8. In WE8ISO8859P1 characters are encoded in *1 Byte* so *1 CHAR = 1 BYTE*. In UTF8 (Unicode) characters are encoded in up to *4 Bytes* so *1 CHAR > 1 BYTE*.
For this reason you'll have to modify the length of your CHAR or VARCHAR2 Columns, or add the CHAR option (by default it's BYTE) in the column datatype definition of the Tables. For instance:
VARCHAR2(100 CHAR)The NLS_LENGTH_SEMANTICS parameter may be used also but it's not very well managed by export/Import.
So, I suggest you this:
1. set NLS_LENGTH_SEMANTICS=CHAR on your target database and restart the database.
2. Create from a script all your Tables (empty) on the target database (without the indexes and constraints).
3. Import the datas to the Tables.
4. Import the Indexes and constraints.You'll have more information on the following Note of MOS:
Examples and limits of BYTE and CHAR semantics usage (NLS_LENGTH_SEMANTICS) [ID 144808.1]For the point *5* it may be due to the conversion problem you are experiencing, it may also due to some special datatype like LONG.
Else, I have a question, why do you choose UTF8 on your Target database and not AL32UTF8 ?
AL32UTF8 is recommended for Unicode uses.
Hope this help.
Best regards,

Import taking too much time in oracle 7i
Hi Guys
I am trying to import a table of around 9600000 rows. on oracle 7i it is taking too much time. any suggestion or way i can speedup the process?
Thanks in advance
KhuranaOk.
Note that it is "_disable_logging" not "disable_logging", but I don't have an Oracle 7 database to confirm if it works.
Been a long time since I used Oracle 7. Any reason why you have not upgraded ? Import should be much faster with 11g ...
For further tuning you would need to look at OS and DB performance to find bottlenecks. E.g run bstat / estat.
Other things to look at are disk performance, increase db_block_buffers, increase db_writer etc. -

All I want is all my contacts on my phone and the same on my iMac, but no, that's too much to ask, instead I get everything doubled up on the phone and everything doubled up (triple in some cases) on the iMac, why does it do this? and more importantly how can I stop it? Thanks
Look under system preferences on the mac at what is be controlled? Look at Mail, Contacts, Calendars. How many accounts are managing contacts? Just the cloud? the cloud and gmail? or cloud, gmail, yahoo, and exchange? If you have more than one contact account, then you will have different contact lists, if John Smith shows up in more than one of your contact lists, you will have multiple entries.
Pick a contact list that is your master, (I use iCloud), only turn on contact syncing for it. The same for your phone. Spend some time on the iCloud webset (www.icloud.com) and work on your contact list there. Clean it up, remove duplicates, etc...Changes will auto sync back to all your devices. Life gets much simplier.
Just remember, if you sync different contacts lists and a large number of people appear in your different lists, then they will appear as duplicates. -
Too much meta data when importing to Flickr
I've noticed that when I export a photo directly to Flickr it seems to carry with it a TON of useless meta data. It happens when I use the Flickr export plug-in as well as updating to Flickr from their site. Here is an example of too much data (basically everything after Compression):
http://www.flickr.com/photo_exif.gne?id=108281029&context=set-1648131
If I retouch the photo in Photoshop then everything below image length is not include (which is my preference). Here is an example:
http://www.flickr.com/photo_exif.gne?id=111724050&context=set-1648131
Has anyone else experienced this? Has anyone been able to change this function? Thanks!I have not used my EOS-M for video but the GoPro 3+ Black files import with all Metadata intact.

I have a whole bunch of CDs that I would like to import into iTunes. If I do that, would the songs still reside on my PC (which would take up too much space), or is there a way to get them "into the Cloud"? Thanks so much
Sign up to iTunes Match, though I'd consider investing in more storage. If space is a problem now then you're probably not backing up your existing media and content, which you should most certainly do.

Report taking too much time in the portal
Hi freiends,
we have developed a report on the ods,and we publish the same on the portal.
the problem is when the users are executing the report at the same time it is taking too much time.because of this the perfoemance is very poor.
is there any way to sort out this issue,like can we send the report to the individual user's mail id
so that they can not log in to the portal
or can we create the same report on the cube.
what could be the main difference if the report made on the cube or ods?
please help me
thanks in advance

Try this to improve performance of query
Find the query Run-time
where to find the query Run-time ?
557870 'FAQ BW Query Performance'
130696 - Performance trace in BW
This info may be helpful.
General tips
Using aggregates and compression.
Using less and complex cell definitions if possible.
1. Avoid using too many nav. attr
2. Avoid RKF and CKF
3. Many chars in row.
By using T-codes ST03 or ST03N
Go to transaction ST03 > switch to expert mode > from left side menu > and there in system load history and distribution for a particular day > check query execution time.

/people/andreas.vogel/blog/2007/03/16/how-to-read-st03n-datasets-from-db
Try table rsddstats to get the statistics
Using cache memory will decrease the loading time of the report.
Run reporting agent at night and sending results to email. This will ensure use of OLAP cache. So later report execution will retrieve the result faster from the OLAP cache.
Also try
1. Use different parameters in ST03 to see the two important parameters aggregation ratio and records transferred to F/E to DB selected.
2. Use the program SAP_INFOCUBE_DESIGNS (Performance of BW infocubes) to see the aggregation ratio for the cube. If the cube does not appear in the list of this report, try to run RSRV checks on the cube and aggregates.
Go to SE38 > Run the program SAP_INFOCUBE_DESIGNS
It will shown dimension Vs Fact tables Size in percent.If you mean speed of queries on a cube as performance metric of cube,measure query runtime.
3. To check the performance of the aggregates,see the columns valuation and usage in aggregates.
Open the Aggregates...and observe VALUATION and USAGE columns.
"---" sign is the valuation of the aggregate. You can say -3 is the valuation of the aggregate design and usage. ++ means that its compression is good and access is also more (in effect, performance is good). If you check its compression ratio, it must be good. -- means the compression ratio is not so good and access is also not so good (performance is not so good).The more is the positives...more is useful the aggregate and more it satisfies the number of queries. The greater the number of minus signs, the worse the evaluation of the aggregate. The larger the number of plus signs, the better the evaluation of the aggregate.
if "-----" then it means it just an overhead. Aggregate can potentially be deleted and "+++++" means Aggregate is potentially very useful.
In valuation column,if there are more positive sign it means that the aggregate performance is good and it is useful to have this aggregate.But if it has more negative sign it means we need not better use that aggregate.
In usage column,we will come to know how far the aggregate has been used in query.
Thus we can check the performance of the aggregate.

performance ISSUE related to AGGREGATE
Note 356732 - Performance Tuning for Queries with Aggregates
Note 166433 - Options for finding aggregates (find optimal aggregates for an InfoCube)
4. Run your query in RSRT and run the query in the debug mode. Select "Display Aggregates Found" and "Do not use cache" in the debug mode. This will tell you if it hit any aggregates while running. If it does not show any aggregates, you might want to redesign your aggregates for the query.
Also your query performance can depend upon criteria and since you have given selection only on one infoprovider...just check if you are selecting huge amount of data in the report
Check for the query read mode in RSRT.(whether its A,X or H)..advisable read mode is X.
5. In BI 7 statistics need to be activated for ST03 and BI admin cockpit to work.

You can go to T-Code DB20 which gives you all the performance related information like
Partitions
Databases
Schemas
Buffer Pools
Tablespaces etc
use tool RSDDK_CHECK_AGGREGATE in se38 to check for the corrupt aggregates
If aggregates contain incorrect data, you must regenerate them.
202469 - Using aggregate check tool
Note 646402 - Programs for checking aggregates (as of BW 3.0B SP15)
You can find out whether an aggregate is usefull or useless you can find out through a proccess of checking the tables RSDDSTATAGGRDEF*
Run the query in RSRT with statistics execute and come back you will get STATUID... copy this and check in the table...
This gives you exactly which infoobjects it's hitting, if any one of the object is missing it's useless aggregate.

Check SE11 > table RSDDAGGRDIR . You can find the last callup in the table.

Music Taking Up too Much Space on my hard drive...
Need some assistance... Have download approx. 30g. of Music Files on my 60 g. 5th. Generation iPod. At the same time I now have 30 g. of back-up files on my laptop hard drive....The music files are now taking up too much memory. I bought an 80 g. external hard drive and have copied all my music files onto it... (Accidentally deleted my downloaded music files last year off of my laptop. An expensive lesson!!! So now I download all music on a seperate external hard drive... Can I delete the existing music files off of my laptop, without losing all the stored music on my Ipod when I reconnect with my library on iTunes? I'd just like to safely remove music files from my laptops hard drive without accidentally deleting music already stored on my ipod! Need the memory on my laptop hard drive for other purposes... Anyone out there that can help me with this? Thanks!!!
iPod Video Windows XPMake sure in edit>preferences>advanced that you itunes points to its new loaction.
Also make sure that itune has copy music into new folder, and organise folder checks ticked to the on position.
Consolidate your library in itunes.
Then go through an double check each folder before deleting it from original location.
This will "copy" music and organise all your music into one location aswell as build Library.
You can add any folder that is missed as you check everything off.
It will not delete anything so you will need to manually delete as it is shifted.
Alternatively you can copy everything in exporer to the desired location & import entire folder into library. Once done, consilidate library, check for dublicates. -
After Effects Ram Preview Drops Frames , Using Strangely Too Much Ram
System Specs :
CPU : Core i7 4770k
Memory : 16 GB DDRIII
Graphic Card : GTX 770 4GB RAM
Storage : 256 GB SSD + 2 TB HDD
OS : Windows 7 SP1
Using After Effects CC 12.2.1.5
NOTE : NOT ANY ADDITIONAL HARDWARE IS ATTACHED TO MY PC . NO SOUND RELATED EQUIPMENT NOR CAPTURE CARD NOR ANY THING ELSE
Hi there
As you Already Don't know I'm an After effects Specialist Using it for quite long time . There is an Ancient Problem with CS6 CC versions . I have a short Small size 1080p Video , about 8 MB , I drag it into project panel and then put it into timeline hence it creates a sequence . There are no Effects and nothing added to timeline , just a small simple video . The Strange Problem is when I click "0" for ram preview , The video starts playing and the green bar above timeline starts to fill . When Ram preview Finishes and plays the video from beginning I See there are several frames Between which are not being loaded to Ram ! The video plays RGB color bar instead of main video and when I check the Green bar above Timeline I see that those frames are being dropped and there is no Green bar above them !
I have had this problem several times before but this time it is too important and the problem should be solved . What is obvious is that some frames are not being rendered or are being deleted after render !
Another Strange problem is that when I open Task manager , It shows AE uses around 10 GB ! of RAM when I press "0" for Ram previewing this video !
So there is a Logical explanation here , Somehow when I do ram preview this video it uses extra ordinary too much ram so AE is unable to load the full video (8 MB) into Ram and hence deletes some of frames .
most of my videos have not this problem and use acceptable amount of ram .I've had this issue with some of my videos till now .
Listen carefully : "This has nothing to do with AE preferences or low memory or plugins . because there is nothing wrong with any individual components of may hardware or software . I have far more than enough RAM for a 8MB video . My Memory has no hardware or software problem . I tested them and if there was any problem with memory or other hardware that should have affected other applications . I have the most recent AE version . I have the most Recent windows updates and drivers . I have a Clean virus free system , and as a computer engineer this strange AE problem is rarely caused by viruses , trust me . I have not any hardware instead of ones a normal PC has . I have not any problem with my whole entire system configuration because I have benchmarked my PC with several up to date softwares . I have tested my PC with almost any STRESS TESTING solutions available for really long period of time , 3 days by IDA64 . Not any driver conflict , dll missing , registry problem have been discovered , as I know perfectly how to solve them ."
I asked some of my friend whom are expert in AE . I handed them my videos and Watched ALL OF THEM HAD THE SAME ISSUE ! So the problem isn't related to my Local PC . What i believe is that there is some malfunctioning or miss coded part in AE source code that decides to reserve such a huge strange amount of ram for such a tiny 8MB video . The point is that the AE works fine , no crash or any problem report . So the AE it Self decides to allocate such huge amount of ram and thinks it is correct ! So I think this is a work around that AE developers in adobe are using to bypass a problem or conflict ! by Using more amount of RAM . I think that there might be some miss understanding between the AE and my installed codec . I installed MEGA CODEC PACK on my PC to enable some new codec supports , and so are some of Windows default de/encoders changed to new ones . I think there shouldn't be any problem But there is something wrong between AE and de/encoder modules !
Please any one with any suggestion , I really appreciate your advices .###UPDATED###
Well thank you guys for your patience ...
as you considered I forgot to mention the codec itself and other stuff ...
The video is in 1080p , 35 sec long , it is a green screen shot , this video is directly downloaded from YouTube and plays perfectly on all tested PCs . here are detailed info :
Format : MPEG-4
Format profile : Base Media
File size : 8.55 MiB
Duration : 34s 993ms
Overall bit rate mode : Variable
Overall bit rate : 2 050 Kbps
VideoFormat : AVC
Format/Info : Advanced Video Codec
Format profile : [email protected]
Codec ID : avc1
Codec ID/Info : Advanced Video Coding
Bit rate : 1 927 Kbps
Width : 1 920 pixels
Height : 1 080 pixels
Frame rate mode : Constant
Frame rate : 30.000 fps
Color space : YUV
Chroma subsampling : 4:2:0
Bit depth : 8 bits
Scan type : Progressive
NOTICE : This video is just for testing the lighting and etc , and so the Sampling and other specs are not considered for broadcast .
I think you hit the point ! Thats K-lite codec pack installed on every machine which the video is tested on ! The point is whats wrong with it ?! I have had never ever any problem with this codec pack !!!
The deadly question : So what are the alternative ways to work with codecs that AE doesn't support ?! because installing codec looks simple and sufficient ! -
Kernal Task in Mac 10.10.2 using up too much CPU
Is it true that kernel_task could be using too much ram its because I upgraded from and old OS: as an example from MAVERICS TO YOSEMITE ? If yes - how do I fix this?
Yes, I am backing up with Time Machine and also an external drive [LaCie]. As I have no other security programs on my Mac other than what the Mac itself offers - I was backup up to 2 external drives - now real do not see if that is necessary or causing additional problems. I checked out the internet and conservatively made some adjustments to System Preference in General and Privacy. I deleted and removed from the hard drive files and Applications which I really did not need - then completely deleted them from Trash. I should have kept a log of what i had done - and certainly will in future particularly if i need to ask for technical assistance. I started this journey because that little coloured twirling disk was driving my husband and me crazy and it took forever to open files and programs. I try to ensure that only those programs that we are using are open. After use I quit them. As we both are Seniors but enjoy the Mac and its freedom its important for me to be as informed about what I need to know about troubleshooting the Mac - unfortunately, the Internet has 60 answers for one question - yours, Mr. Davis, has been the most functional and analytical response so far. If you can bear with us perhaps you can direct us to where we need to go. I will say that after all the tweaks this morning - the system is running better ... although I really cannot say what the specific action were, if any, that made the difference. I should mention that our internet provider suggested that we weekly reboot our WiFi connection. Any assistance or direction you might recommend for future maintenance will be most gratefully appreciated.
