Is write mode faster than append mode?

Hi All,
I have to write some data after selecting from a table. I have to call six procedure to write data. Each of the procedure writes around 100-150MB data.
If I generate six files in write mode it takes around 11 minutes. (using utl_file.fopen('/tmp','csv','w');)
but if i generate 1 file (combining all) using (using utl_file.fopen('/tmp','csv','a');) It has passed 55 minutes an size of file is still around 500 MB and still growing.
Can anyone explain why append is so slow comapred to write ? or there is any other reason .. note that we have lot of space on server.
Regards,
Amit

What you've written does not compute.
On my laptop I can write that much data far faster than what you've indicated you are seeing.
What version number?
How is the data being selected?
How much time does the SELECT take without the WRITE?
When I have large amounts of data to write my method of choice is to concatenate them into a CLOB and then write it out using DBMS_ADVISOR.CREATE_FILE

Drive does not write CDs faster than 16x despite advertised speed of 24x

CD tested was a 48-52x Verbatim branded pthalocyanine made by CMC Magnetics.

I think it depends on what your burning (data, music, etc.) and the data under run buffer... so "bad" CD's don't get created.

Corrupt file error while writting a file in compress mode

Hello,
I have a scenario where i am writting data in a file in appending mode with filter 'compress' addition using open dataset, on Al11 for the first set of records it works fine but if this file is accessed again for writting data in next select statement ( its between select endselect),the file is getting corrupted, if i try to open this file corrupt file error come. can someone help.
Thanks and Regards,
Gunjan

Hi Gunjan,
Unfortunately, you can't do in that way. The behaviour of that OPEN and FILTER 'compress' clause is to create a compacted file, to be read later, but it can be appended... all your writes go to a pipe and when you close the file this is sent to 'compress' program or other filter and than a compacted file is created.
You can't go back and start inserting again after close it.
Follow documentation:
http://help.sap.com/abapdocu_70/en/ABAPOPEN_DATASET_OS_ADDITION.htm
The addition FILTER must not be used together with the addition AT POSITION or for the access type FOR UPDATE.

File in appending mode

hi all
when i try to write to a file i just have the last line added and the pervoiuse ones are overwritten
how can i keep everything added to the file appear??
what is the appending mode for the file to keep accumelating things rather than overwrite them??

ok here you are
     PrintWriter outT=
                    new PrintWriter(
                      new BufferedWriter(
                              new OutputStreamWriter(
                                      new FileOutputStream("D:/eng.txt"),
                                      enc)) );
           outT.close();
//These   appending mode
           outT = new PrintWriter(
                      new BufferedWriter(
                              new OutputStreamWriter(
                                      new FileOutputStream("D:/eng.txt",true),
                                      enc)) );maybe the problem is with the menu?? cos each time i use getSelectedText() and then i add the selected text to the file and after another select also i want to keep it in the same file
so select add then select add and so on but each time i just have the last choosen text
what is your suggestion now????

Problem with Append mode in File Receiver

Hello,
I am facing some problem with Append Mode in File Receiver.
In channel config, i have given :
Construction Mode : Append
File Type : Text
Message Protocol : File Content Conversion
The size of the file which i am trying to send is about 9.5MB.
I got this error,
"Recovering from loss of connection to database; message
loaded into queue by recover job: System Job (Failover Recovery)".
So, it would seem that there was a loss of connnection to the database
while the file was being written.
Note - XI successfully recovered from the connection loss and
successfully wrote the file, however since the communication channel
was set to append, it appended to the partial file that was written
before the database connection loss. This is not correct. The file
should have been overwritten after the recovery even though the communication
channel was configured to append.
Can anyone help me on this regard.
Thanks,
Soorya.

Hi Venkat,
I would suggest u to split the file in to chunks if u face any problem in processing at a time in append mode and also
Memory Requirements are must 4 processing huge files:
Q: Which memory requirements does the File Adapter have? Is there a restriction on the maximum file size it can process?
A: The maximum file size that can be processed by the File Adapter depends on a number of factors:
o The most important one is the size of the Java heap, which is shared among all messages processed at a certain point in time. In order to be able to process larger messages without an out of memory error (OOM), it is recommended to increase the size of the available Java heap and/or to reduce the concurrency in the system so that fewer messages are processed in parallel.
o Another factor negatively influencing the maximum message size in releases up to and including XI 3.0 SP 13 is an enabled charcter set (encoding) conversion if the message type is set to "Text".
o Using the transport protocol "File Transfer Protocol (FTP)" also uses more memory for processing than the transport protocol "File System (NFS)" (up to and including XI 3.0 SP 13).
o If the Message Protocol "File Content Conversion" is used in a File Sender channel, consider that not only the size of the input file affects the File Adapter's memory usage, but even more the size of the XML resulting from the conversion, which is usually a few factors larger than the original plain text file.
To reduce the memory consumption in this scenario, consider configuring the setting "Maximum Recordsets per Message" for the sender channel. This will cause the input file to be split into multiple smaller mesages.
Plz do refer the following links:
U may plan the availability of ur communication channel using "Planning Availability Times" feature

Neo Bios 1.6 and Slow/Fast/Turbo/Ultra Modes

Can anyone tell me what the difference is between the Slow/Fast/Turbo/Ultra modes in Bios 1.6 on the Neo boards?
The only mode I can get to work is the Slow mode. On all the rest, Win XP boots OK, but when I would run programs, the screen would lock for a few seconds, then come back in low resolution stating I had an unspecified "device failure", and I had to restart my computer for it to work properly.
In any case, I have no clue what the difference is between modes. I was able to complete a 3dMark test while in Turbo mode, and compared it with one run in Slow mode, and the differences were minimal.
Can anyone enlighten me?

No OC, Timings = by SPD, DRAM Frequency = Auto (200/400)
Slow/Fast/Turbo/Ultra-Turbo results
AIDA32 Display/GPU
GPU Clock 200 210 210 210
Memory clk 458 (no change)
AIDA32 Motherboard/Motherboard (Effective clocks)
FSB 809 (no change)
Mem 404 (no change)
Chipset 270 404 404 404
SANDRA MAX3 Memory Benchmark
INT 4340 4837 4956 5099
Float 4390 4834 4970 5048
PAT OFF ON ON ON
Timings 2.0,4,4,6 2.0,3,3,6 2.0,2,3,6 2.0,2,2,6
"Slow" disables PAT/MAT and reduces the chipset bus frequency to 66Mhz (quad pumped)
"Fast/Turbo/Ultra-Turbo" Overclock your video card!!!
If you set your memory timings manualy or use a ratio other than 1:1 there will be no difference between Fast/Turbo/Ultra-turbo (only difference being "by SPD" memory timings) -as far as i can tell
There maybe other differences but not found them ....yet

Creating file in append mode

Hi All,
I have below problem, please let me know your views.
I have requirement to trigger huge data using proxy from ECC and create a single file out of it on file server. Since the data is huge, in order to avoid performance issues, I am planning to trigger multiple message from ECC to XI. Say after every 2000 records are processed, proxy message will be triggered to XI and the program will continue execution.
Now my problem is on the receiver side I need a single file to be created out of all the messages triggered from ECC during a single run. This i think can be done using File adapter in "Append" mode.
However the problem is, data will contain 1 Header record and multiple Item records. In append mode the Header record will be appended multiple times in the file which is not desirable.
Is there any way to avoid this?
Is there any other approach that is feasible in this case where in I need to extract large data from ECC using proxy program and write it to a single file?
Thanks for your help.
Anand

Hi Anand,
I also faced this requirement and solved successfullyby using CREATEIF node function. Please follow below approach...
So your proxy will send several files which you need to create as single file at receiver side. First file only has to create with header. So for this The proxy data which is coming first time should have header data, now compare in mapping whether header data coming in sender proxy data or not. If Header data coming then by using CREATEIF node function, create the target header structure in mapping(target header structure should have 0..1 occurance). If header data is not coming in sender proxy(this is not first proxy execution as it is not having header data) CREATEIF node function doesnt create the target header structure.
In receiver file adapter select append mode so that first time file will create with header as CREATEIF node function create the target structure and for the next executions of proxy it will create only data records.
thanks,
madhu

How to use text_io package in append mode

dear all
I'm using text_io in my form. onece it executes read the content of the file in a text file. next time it will over write the content of the file.
I want to get the all the data in to the file rather overwriting the content. Is there any way to set the cursor potition into append mode?
thanks

Try out:
TEXT_IO.FOPEN built-in function
A Open the file for reading and writing without deleting existing lines (that is, appending).

No Boot with Performance Mode FAST

When I set Performance Mode other than SLOW (no matter if FAST or TURBO) my system won´t boot (all other settings default, D.O.C. DISABLED).
This happened with Bios v1.9 and also happens with Bios v1.7 (re-installed hoping it might solve the problem)
NO way activating MAT/PAT
Any help very appreciated
System:
MSI 865PE Neo2-FIS2R (MS-6728)
Intel P4 3.0 GHz FSB800 HT (default)
Zalman CNPS 7000A-CU
2x 512 MB Twinmos Winbond DDR400 CL 2.5
MSI GF4Ti4200 (MS-8870)
Samsung SP1614N 160GB 7200rpm 8MB
Soundblaster Audigy 2 ZS
Pinnacle DC10+ v7 Videocard
LG GSA-4040B
LG DRD-8120B
Tagan TG-380-U1 380W
Windows XP HomeEdition SP-1

This might be a long shot...but try the following settings if you want PAT/MAT:
Bios 1.9 for 865pe
FSB=201
Vddr=2.70V, or higher if it doesn't work
Memory freq= AUTO (If you set it to 400 mhz you won't get MAT)
Performance Mode= TURBO (FAST increases AGP/PCI bus)
Timings= depends on you ram, set it manually to whatever specifications you have (If it still doesn't work, try setting to SPD)
If all of this doesn't work then set memory freq to 400Mhz and Performance mode Turbo, or Ultra Turbo and you WILL get higher performance even if you don't have PAT/MAT. Test this with Sandra and you will see that the memory bandwidth is almost as high as with PAT on.
Recommended: Install ClockGen and set it so that it loads with windows. Use it to set the FSB to 200 and AGP/PCI 66/33 for added stability.
Please post back to see if this works for you guys. Good luck!

G5 won't boot other than 'safe mode'

I've got a first gen. G5 DP1.8 I use exclusively at work. My system locked two days ago, so I forced quit and restarted.
After that the system attempts to boot, then aborts. Came in yesterday morning and it fired up, fine. Restarted just to check it out and that was the last time it has booted in anything other than safe mode. I've reset the PRAM, NVRAM, PMU/SMU, repaired permissions, cache, all the usual stuff. I've tried removing startup items, etc. Seems to be a startup issue as the unit will boot in 'safe'. Finally out of frustration, I upgraded the OS to 10.3.8 thinking that could repair whatever startup issues, but no. I CANNOT get the machine to boot. I get the chime, booting screen, mac icon, and spinning, then it shuts down.
Here's part of the system log if it helps (the first half is an attempted normal boot, the second half is safe mode):

Apparently this has something to do with temp? The
machine will cold boot first thing in the morning
with no problem, but once it's been on for a couple
of minutes it will not restart (except in safe
mode).
It sounds like you have some component changing value with heat. It's hard to tell if it would be on the logic board or in the power supply though without swapping them out. It's strange it starts in safe mode though. Did you try resetting your open firmware?

Error in Seeburger SFTP receiver in append mode.

Hi,
I am trying to do content conversion in Seeburger SFTP adapter at the receiver side and was successfully able to create the first CSV record.
I am using append mode in receiver adapter.
But when sent another record from sender; I got below error.
Always, first record gets processed successfully then second and subsequent records always fails.
Message processing failed. Cause: javax.resource.ResourceException: Fatal exception: com.sap.aii.af.ra.cci.XIRecoverableException: >> Description: putFile: Target filename <out.txt>; Flags set: appending=<true>; ; Reason: Failed to convert Ace to the native form.>> Details: putFile: Target filename <out.txt>; Flags set: appending=<true>; ; Reason: Failed to convert Ace to the native form.>>SendingStatus: NOT_TRANSMITTED>>FaultCategory: COMPONENT_ERROR>>Retryable: true>>Fatal: true, >> Description: putFile: Target filename <out.txt>; Flags set: appending=<true>; ; Reason: Failed to convert Ace to the native form.>> Details: putFile: Target filename <out.txt>; Flags set: appending=<true>; ; Reason: Failed to convert Ace to the native form.>>SendingStatus: NOT_TRANSMITTED>>FaultCategory: COMPONENT_ERROR>>Retryable: true>>Fatal: true
Regards,

An update.
Error message "Unable to convert ACE to native format" means it is not able to convert A SCII C ompatible E ncoding to the native encoding which is used in file system.
I am unable to make head or tail of it... I am doing content conversion in adapter module tab and have specified Transform.ContentType = text/plain;charset=utf-8
The file which gets generated is of ANSI encoding and doesn't appear to be a problem as it works when the file gets generated for the first time.
Also, it works OK when I use unique file name in receiver adatper where 1 file for each record is generated.
The problem is only in append mode.
When checked in Seeburger RWB, there was inconsistency in file details for messages.
For the successful message, file details were:
File details
Host LTFBG-ANIRUD-PI.com
Path /out
File name OUT.CSV
Remote file name OUT.CSV
Detailed status description PUT command for file <OUT.CSV> has been performed successfully.
whereas, for failed messages it was:
File details
Host LTFBG-ANIRUD-PI.com
Path /out
File name null
Remote file name null
Detailed status description Error on send, will be retried
Could that be product error?
Has anyone faced this problem before?
regards,
Anirudh.

Open file in append mode

I am using JSR-75 for file IO. How can i open a file for writing in append mode?

Don't create multple threads on the same topic:

Creating a file in append mode

Hi All,
I have a requirement where in i need to create a flat file in append mode . The requirement is as follows :
- In a week , SAP sends certain number of IDOCs to XI . For the first IDOC that comes in ,XI has create a file and later for the rest of the IDOCs ,XI just has to append the file contents .
- During the End of the week , the target system picks this file for processing.
My file structure is as follows:
Header
seg1
seg2
seg2
seg3
seg3
seg1
seg2
seg2
seg3
seg3
Trailer.
So ,while creating a file in append mode , is there any way apart from creating one more interface to pick the finally created file , i can make sure that the file gets written in the above format without header and trailer getting repeated.
Regards
Vinay P.

Hi, Vinay
If you don't want to use a new interface, you can use a operating system command in your target communication channel..
The OS script must:
pick up only one header line and move it to a temporal file. For example, with UNIX command you can do that with
grep "criteria" file | head -1 > temporal_file
pick up each detail line and move it to the temporal file.
pick up only the last trailer line and move it to the temporal file
Rename temporal file to final flat file.

Carme.

IPhone 4 Video Mode image is larger than camera mode. Normal or Bad?

Hey there, im using an iphone 4 White. I start to browse through my device.
But something caught my eyes. Which is the video Mode.
So this how it goes, when i view my device in camera mode everything is normal.
But i switch to video mode, the image became large. Its like the device automatically zoom in..
Becaus of this, each time im taking a video, i need to take a step back..
So what im asking now is, is there any chances that it can be fix... For what i know, when im using my iphone 3gs everything works fine.
So Do help me find a solution to my curiousity.. Thank You.

I'll try to give you an explanation; I hope it's clear.
When taking a photo the iphone uses the full camera sensor (2592 pixels by 1936 pixels).
Which gets the full wide view of the lens.
In order to record video the iphone appears to only use the middle of the sensor to record (1280 pixels by 720 pixels); and it ignores the pixels around it.
Which then cuts down the field of view by almost half; and that looks like it has zoomed in.
Have a look at my diagram, red is the photo mode, blue is video mode:
This is a limitation of the hardware, as it might not get faster data from the sensor to allow the camera to shoot higher resolution, or a wider field of view.
It actually allows the iphone camera to not have as apparent aliasing issues, but certainly lowers the field of view.
Other cameras can "skip" lines to record video.
This allows for much wider field of view, but it does introduce pronounced aliasing issues (as information is "lost" inbetween the lines).
So this probably won't be fixed in the iPhone 4; although video was "added" to the older iphones by developers, it isn't likely to be that easy on the iphone4.
But you will probably hear of a higher pixel count camera in the iPhone 5, and it will possibly be able to take higher resolution video; but in a similar way it will probably only use part of the sensor.
I hope this makes sense?

About "Append mode" of cs6, cc & cc2014 project file in order to insert xml sequence which is sent from 3rd-party tool

let me ask you all something about “Append mode” of cs6, cc & cc2014 project file in order to insert multiple xml sequence which is sent from 3rd-party tool into specific project file .
Finalcut pro 7 & x was supported this , but i am not sure will support this on cs6, cc & cc2014 .
is this possible ??
could someone let me know about this - append mode possible or not ??

Is write mode faster than append mode?
