Logical end-of-file reached during read operation

Hi,
Something strange happened to my Logic a couple of days ago - all of a sudden. When I start Logic up it gives me the following error message:
*Error reading/writing file “com.apple.logic.pro.cs”: Logical end-of-file reached during read operation.*
I have re-installed Logic, as well as updated it (8.0.2), I have repaired disk permissions in Disk Utility, and it still keeps popping up. I cannot get on with my projects and I have deadlines!
I found an IT support site, according to that I don't have enough space on my HD. However, I do... I'm confused, and desperately need help.
Thank you so much, I'm looking forward to hearing from somebody.

I am not opening any files, just launching Logic.
I know. And when you launch Logic, it loads its preferences files - and it seems this is failing - most likely due to file corruption. So delete the file, as I said, and Logic should load fine.

How can I configure ReFS to NOT fail read operations when a checksum error is detected (on non-Storage-Spaces volumes where data integrity streams are enabled)?

According to William Stanek, in his Windows Server 2012 R2 Inside Out: Configuration, Storage & Essentials book, this is apparently possible: (pg. 615 - here it is on Google Books: https://books.google.ca/books?id=0IyfBAAAQBAJ&pg=PT819&lpg=PT819&dq=read+operation )
Integrity can be enabled when the system is not running on Storage Spaces. When
integrity is enabled and ReFS detects a checksum mismatch, ReFS logs an event and
fails the read operation by default. If you don’t want the read operation to fail, you
can configure ReFS to continue with the read operation. A related event will be logged
regardless.
So then how do I configure it to do that???
(And just to make it super-clear, I'm NOT using Storage Spaces, so there is no redundancy via mirroring/parity, and I'm not expecting any file repair - just detection of corruption. It's just a basic volume formatted with ReFS and
with integrity streams enabled, via format E: /fs:ReFS /i:enabled
For those who want more details, here's the situation:
I try to perform a read operation on a file with corrupted data (purposely done for testing using a low-level disk editor), I get a the following error message:
And an event ID 133 from ReFSv1 gets logged in the System log:
Clicking "Try Again" just brings up the same message, and clicking "Skip" skips the operation entirely.
This is indeed the correct default behaviour.
What I want instead is for the read operation to be allowed to complete, with corrupt data and all, and ONLY for the event to be logged. And according to William Stanek, this is supposed to be configurable somewhere - and after hours of searching, I haven't
been able to find anything.

Hi Tommy,
>>How can I configure ReFS to NOT fail read operations when a checksum error is detected
We can use PowerShell command Set-FileIntegrity to configure this. The specific parameter for controlling this behavior is
-Enforce <Boolean>which indicates whether to enable blocking access to a file if integrity streams do not match the data.
Regarding this point, the following article can be referred to as reference.

File Adapter read Operation

I am using File adapter to read files from the given location.
With this read operation it picks all the files at time.
I want to configure File Adapters that it should pick one file at time from the given location with given polling interval.
Can we do this with file Adapters in BPEL.
I am using SOA Suite 11g.
Thanks,
Arun Jadhav

Hi, in order to achieve that you need to set the "SingleThreadModel" and "MaxRaiseSize" properties for your file adapter.
Edit the adapter's jca file and add the following properties:
<property name="SingleThreadModel" value="true"/>
<property name="MaxRaiseSize" value="1"/>
You can set these properties also through jdeveloper, by opening composite.xml, selecting the adapter and then changing the properties through the properties panel.

Keep getting message pop up "Error reading/writing file "com.apple.logic.pro.cs": Logical end-of-file reached during read operation," and "The Preferences are not loaded completely. Save them to "com.apple.logic.pro.cs" anyway?" Using Logic pro 8. ???

Logic froze while I was working on something so I forced quit. Now every time I open LOGIC a message pops up that says:
"Error reading/writing file
“com.apple.logic.pro.cs”:
Logical end-of-file reached during read operation."
The only button option is cancel so I press it and another message appears that says:
"The Preferences are not loaded completely.
Do not save them, as you would overwrite the Preferences file with incomplete data."
Then when i close logic a box appears saying:
"The Preferences are not loaded completely.
Save them to "com.apple.logic.pro.cs" anyway?"
There are 3 button options to press; ok, cancel or dont save.
I press "don’t save" cuz I don't want to ruin anything.
I found a discussion located here: https://discussions.apple.com/message/9564253#9564253 that says if I delete the file "com.apple.logic.pro.cs" it will resolve the problem. If I do this will I loose or mess anything up at all, automation, saved channel strips customizations, saved effects, synth, or ultrabeat customizations etc? Or especially will I loose any work I've done? I have hundreds pieces of music files I've created. I'm scared to mess anything up with all the hours and months of work I've done. Is there anyway to fix this without loosing anything? I'm using Logic Pro 8.
Thank you

You can safely delete this file - its the preference file for control surface settings - you haven't said whether you're actually using a control surface or not, if so, you will have to set it up again. A new file will be created when you fire Logic up again, but of course it will contain default settings. If you have a complicated control surface setup, remember to keep a backup copy somewhere in case any future problems arise.
Other than that, you really have nothing to be scared about - hopefully your problem is as simple as that and there isn't an underlying problem (a corrupt hard drive, for example). You seem concerned about losing work, so I guess you want to think about backing that up on a regular basis too. If you're saving your projects to your system drive, do get an external one for this. And also check that you have plent of free space on your system drive - you need to keep about a quarter or third of it free for your OS and programs to run properly (some temporarily stored files can be quite large).

Error "logical end of file reached during read operation"

I am trying to burn a dvd of a wedding I did, and this is the error I am getting. After 5 hours of it trying to burn when I click cancel this it says " logical end of file reached during read operation". Does anyone know what this means, and how I can fix it? I am anxious to get this wedding finished and out to the customer. Any help would be greatly appreciated.

How long is the wedding video?
My standard list of things to do first...
Run MacJanitor (free download) to do all the Unix Cron Maintenance scripts.
Run Disk Utility (Applications -> Utilities) and repair disk permissions on your start up drive (typically your internal drive). Also verify any other drives mounted on the system.
Run Preferential Treatment (free download) to check for corrupt/damaged application and system preference files.
Run Cache Out X (free download) to clear all system and application caches.
Reboot your Mac.
If you still can not get it to run correctly, next thing to try is to throw out the iDVD preference file (don't forget to change back those preferences you want different from the defaults next time you run it). If it still doesn't work, then I would suggest you reinstall iDVD.

EXS 24 Logical end-of-file reached during read operation Result code = -39

EXS kit Trip Hop Remix will not completely load. Upon trying to load it I get the error, Logical end-of-file reached during read operation Result code = -39. The kit ends up lacking samples. It worked at one time but now it will not load up. To try and fix I extracted two kits with the same name but oddly they are slightly different sizes and have different creation dates, one 2004 the other 2007 hmmm (one goes in Garage band for remix tools the other gets placed in 02 Electronic Drum kits) from the install disks using Pacifist hoping to replace corrupted files. NG. I also reinstalled all the samples from the LP8 install disk, still NG. Anybody have a solution. THanks.

To further clarify, the samples are all located in the folder Garage band/.../.../.../Sampler Files/Treated Percussion Sets/Perc-DnB+Triphop. They are used in the EXS24 Trip Hop Remix kit.exs. The 3 samples that seem to be causing the error are, YT2BGLRHTX02_3ue.aif, YT2BGLRHTX03_3ue.aif, YT2BGLRHTX04_3ue.aif. The kit is useless and my song is screwed up now that the kit will not load. Any ideas for a fix out there ?

Error: Logical end-of-file reached during read operation. Result Code = -39

Hello all,
Recently, I have been suddenly getting this error message:
"Logical end-of-file reached during read operation. Result Code = -39."
In my case, when it does come up, it always pops up during the recording of an audio take. Almost immediately after hitting the stop button, this error message would pop up. And then when I go to check the take that was just recorded, there is nothing but shrieking noise. As a result, this pop up error trashes any good take I may have had. It's unpredictable as to when this error decides to pop up as well. So now, when I record, I tend to just have my fingers crossed and hope that this error doesn't pop up especially right after recording a good take!
To no avail, I have tried different I/O buffer settings, repaired permissions, rebooted, and even re-formatted my recording hard disk.
Could this be a possible hint that my hard disk is about to physically collapse? I have had it for about 2 years. Could it be some sort of bug in Logic? Or something else perhaps?
Appreciate any feedback! Thanks a lot!

Thanks for those suggestions Erik...
It's been happening for a month I guess and I don't think that anything new's been installed. I will try recording to the start up disc and to maybe to some USB discs I have.
It seems to happen after working on a project for some time.
After say tracking takes for 45 mins or so. Maybe it's just coincidence, but do you think that might indicate a hardware issue?
Now there might be a clue. What happens when you then quit Logic, reboot your Mac, and reopen the active session? It might be that your disk has become a bit messy from all the traffic, and it just needs to 'settle' in OS X again. Click on the *Spotlight icon* top right of your screen and see if any indexing is taking place. Wait for it to finish before launching Logic.
Alternatively, you could exclude your recording disk from Spotlight indexing alltogether, by dragging the disk to the Privacy field in the Spotlight Sysprefpane.
One other thing to do: turn off Journaling , using *Disk Utility.* Select your recording volume in Disk Utility, hold the alt key while dropping down the File menu. Choose *Disable Journaling.*
On the other hand, it might also point to a RAM issue. Do you ever suffer Kernel panics (=the darkening 'curtain' and the message "You need to restart your Mac... etc")? or 'unexplained' crashes? If not or very rarely, I'ld rule out a RAM issue. If daily, it could be. What you can try in this case is to turn of your Mac and physically take out and reinsert your RAM.
And when you trash (=eject/unmount), physically disconnect and reconnect your recording disk? Does that help? (Logic should not be running when you do this)

Cisco SG300 HOSTP_flash_operation: fatal error during read operation!

I have 2 Cisco SG300-52P switches. Earlier this week, one of them started dropping connections and POE was not working on a couple of devices... I came in this morning to restart them when no one else was around. After restarting them, the troublesome one was still not detecting POE devices.
I have been waiting for some down time to do a firmware update, so I thought this might straighten things out. I Downloaded the updated bootloader and firmware from Cisco's site. Updating the (non-problem) SG300 went exactly as it should. Upgrading the the bootloader on the problem SG300 went exactly as it should. Started the firmware update on the problem switch ....... and it didn't come back online. The power light was flashing, and occasionally the lights on ports would blink like they were trying to reset, but they never made it. There weren't really any special configurations on this switch so I had nothing to lose by trying a factory reset via the pinhole on the front ...... same result.
I connected to the serial port via a win7 PC with putty. .. All setting per Cisco. I got a message that the connection was detected, but it would not accept keyboard input. I power cycled the SG300 and watched the messages go by ... It looked like everything was working. I even got a message that the "Initialization task was completed"..
Then this message "HOSTP_flash_operation: fatal error during read operation!"
We have had a couple of internet and power outages recently, but I am trying to rule out other issues before blaming it on that.
any suggestions?
putty output file attached

I am not familiar with SG series products, but looking at the error message in the attached file, it appears there is an issue with reading from the flash. It could be that the flash file is corrupted and the flash needs to be formatted and then reload the software again.
If you have support contract on the product, I would suggest you open a TAC ticket with Cisco and have them help you.

JZ0T3: Read operation timed out

Hi! I'm trying to solve this problem for a while and actually I couldnt find the cause of the problem.
For some reason, deep inside the code of my application that error happends when I execute some inserts on the same Sybase table (they could be performed concurrently). I said "deep inside the code" since if I test a similar code, but outside the application (that is, just executing the inserts in a stand alone java main) the problem can't be reproduced.
The connection is obtained normally as follows:
try {
Class.forName("com.sybase.jdbc2.jdbc.SybDriver");
}catch (ClassNotFoundException e) {
System.out.println("Oops!");
Connection conn = DriverManager.getConnection(url,user,psw);
conn.setAutoCommit(true);
The driver been used is jconnect 4.5
Then, several inserts are performed:
String exampleQuery = "INSERT INTO SampleTable (id) VALUES ("1")\nSELECT @@IDENTITY";
PreparedStatement stmt = conn.prepareStatement(exampleQuery);
ResultSet rs = stmt.executeQuery();
if (rs.next())
System.out.println(rs.getInt(1));
Some of the query executions raise the following exception:
java.sql.SQLException: JZ006: Caught IOException: java.io.IOException: JZ0T3: Read operation timed out.
     at com.sybase.jdbc2.jdbc.ErrorMessage.raiseError(ErrorMessage.java:485)

     at com.sybase.jdbc2.tds.Tds.nextResult(Tds.java:1796)
     at com.sybase.jdbc2.jdbc.ResultGetter.nextResult(ResultGetter.java:69)

     at com.sybase.jdbc2.jdbc.SybStatement.queryLoop(SybStatement.java:1455)
     at com.sybase.jdbc2.jdbc.SybStatement.executeQuery(SybStatement.java:1440)
     at com.sybase.jdbc2.jdbc.SybPreparedStatement.executeQuery(SybPreparedStatement.java:70)
I've just found a workarround to solve this problem: synchronizing the execution of the query. That seems to avoid concurrent insertion.
The funny thing is: when I extract the code from the application and execute it in a stand alone java main, even stressing with multiple threads executing batch inserts in a for clause, the problem NEVER happends.
Any tip is welcome since I actually don't know what to do. Thanks a lot, I hope anyone replies!!
Bye!

Hi Sean,
I informed the senior developer and she said she has emailed the Oracle regarding this issue. We are developing a website for a company who has purchased the Oracle CRM on demand.

Need file adapter polling with read operation to be triggered by a BPEL without using synchronous read

The scenario is:-
Web Service Client -->input-->BPEL-->if input valid-->trigger file adapter with read operation--> receive file
i am not able to stop the polling until it is required to trigger the polling.
As soon as i deploy the composite the file adapter starts polling without waiting for input.
Since i am using two receive activities, the second one which is suppose to receive file from file adapter is always showing pending state. (asynchronous callback)

Hi there,
IMHO the traditional read is used only as inbound operation, that means
that it starts polling the input folder as soon as the composite gets
deployed - which is the same you are experiencing.
In your case you need an outbound operation that needs to be invoked at
a certain moment. I don't know what are the reasons not to use sync
read, but this is the only outbound read operation supported by the
adapter. If you can not use the sync read, then you would have to design
some custom solution where you call a web service or EJB for instance
that reads the desired files.
Another option I can think of, though have not use personally is using
the adapters programatically in Java - take a look at this blog post as
it seems related to this topic -
https://technology.amis.nl/2012/01/22/using-the-oracle-weblogic-technology-adapters-with-custom-java-message-driven-bean-mdb-triggered-by-file-adapter-part-of-the-story/.
Hope this helps,

Multiple File Location in Read operation in File Adapter.

Hi,
I am using File Adapter for Read operation. Normally we would make a Logical Directory for reading files at that location. But I have come up with a scenario where we need to read file from 6 different File locations.
Is there any way that the same BPEL process can read file from 6 different locations.
OR
Do I need to make 6 BPEL processes to read file from 6 different locations.
I am using Oracle SOA 10.1.3.4 and JDeveloper 10.1.3.4.
Will really appreciate if someone can help in this regard.
Thanks for the needful.
Cheers,
Varun

Hi Oracler,
Thanks for your reply.
As suggested, the BPEL process with six different file adapters for six different directories and put them on each of the six branches of the pick activity. Will there be any performance oriented issues if you use six adapters for polling at 6 different locations??
Also, the other solution that you have provided from this link Re: Can we have dynamic folder for Polling in BPEL works fine. One of a problem that I encounter while using this solution is that everytime you do any chnages in your BPEL process, the entries from bpel.xml are missing.
Thanks for the needful.
Cheers,
Varun

Can Scheduler be used in ORACLE SOA to trigger FTP Adapter read operation

I need to create an ESB project where scheduler should trigger the File/FTP Adapter read operation.
Where can I provide the time settings viz. (xx HR: yy MM: zz SS everyday)?
Is it possible in Oracle SOA?
Please provide any tutorial where scheduler has been used to invoke the File/FTP Adapter rather than invoking it real time (gets triggered the moment files are placed).
Thanks

You should the quartz timer within the SOA Suite to obtain this functionality.

ViClose session not called after Read operation Timeout in an IVI COM driver

Hi everybody
I have a small VI sample that is initializaing an IVI COM driver for an OPM instrument, set some parameters into the instrument then is doing a single Read power measurement. My Read operation receives a single parameter called MaxTimeout that user could change depending on his own interest. Inside the Read function I change temporarily the VISA query timeout to user timeout but at the end of Read operation the original VISA session timeout is reverted to its original value before Read operation was called. If the Read operation timeout is long enough for the Read operation to complete ( 100 ms or more) the VI is doing its job and when finished the viClose is called twice for DefaultHandler and for OpenHandler.
If the Read operation timeout value decrease ( 50 ms) then Read operation could not be completed and a Read Operation Timeout error is thrown from inside this method. This error is then propagated trough Error path until the VI end in a Simple Error Handler. Now on my VI I close all open references to my driver interfaces but I don't know why VISA itself is not calling viClose on the DefaultHandler and OpenHandler as in the case when was no VI error. I could see all these diferences in my NI Spy window and I could post this if that could be of any help. Bear with me cause I am more a C, C++, VB programmer and much less of a LabVIEW programmer. BTW the Error Handling from LabVIEW looks a a little weird and the only sure thing is that I wired in Error In and Error Out path in all my VI calls. What kind of error handling should I perform on the Read method in order for VISA to close properly both OpenHandlers even if there is an error in my VI?
Thansk
sorinvalea

So viClose is not called by VISA after an error takes place in a VI that is calling some operations on an IVI COM driver.
I discovered that all VI sessions opened trough VI that encountered a timeout error in Read operation and that were not properly closed after VI completed are in fact viClose by the LabView itself when I am closing LabVIEW application.
So these left over open vi sessions are kept aside by LabVIEW until it closes itself and then clean them one by one by calling viClose on them....

Passing file name dynamically in Synchronous read operation of FTP adapter in OSB

Hi,
We are implementing the integration in OSB 11g and using FTP JCA adapters to check if the file exists in the FTP location or not. We are using Synchronous read operation of FTP adapters. We need to pass the file name dynamically at run time. In the JCA file we can hard code the file name. How that file name can be taken dynamically using OSB.
Regards,
Sharmistha

Hi Sandeep,
This is possible.
For creating filenames dynamically for your sender, you will have to crate a variable name ( eg: %VAR%) as you file name and then you will have to give the name of your file under variable substitution. Just check this link for more info,
http://help.sap.com/saphelp_nw04/helpdata/en/14/80243b4a66ae0ce10000000a11402f/frameset.htm
In the case of receiver file adapaters, you have 5 options for file creation like,
1.Create
2.Append
3. Add time stamp
4.Add Counter
5. Add Message ID
You can choose any of these options or you can do it dynamically from you payload. Just check out this help link for more info,

Invoking Composite from BPMN with file read operation

hello,
I have a composite which does a simple file read and dumps data to database using mediator.
right now composite gets kicked off by presence of a file in a directory.
I would like to invoke this composite from a BPMN process, unfortunately because of nature of file adapter created through composite, jdeveloper doesn't expose the FileAdapter read operation as WSDL so I cannot create a service task out of it.
How can I invoke composite directly without having to create a file adapter at the BPMN level and take care of transforming the records to DB adapter?
thanks.

As you guess, it is stored in the PSD, but only with the Maximise Compatibility switch. Without that switch, a dummy image is stored which has the text "This layered Photoshop file was not saved with a composite image.", in English, German, Japanese and French.
My program
psdparse extracts each layer in an 8-bit file as a PNG, and the merged image for both 8- and 16-bit files. That link is to a Subversion repository containing source code.
