Cannot load " file reference ": Domain object with ID " guid " has already been defined in this or another domain model.
The file to be loaded is a DevExpress xpo data model file and the file itself has successfully loaded on at least 3 prior occasions.
I have searched for the ID guid on the whole hard disk without any result.
How can I fix this?
The problem here is, you have already compiled the file. Look around in your build path for a compiled file, and either move or delete it. Whenever a file is already compiled in a location, the compiler tries to use its resources in the compilation of your new program. This then defines things multiple times, giving you this error.

I use boost log by this config.
[Sinks.2]
Filter="%Severity% >= 2"
Destination=TextFile
AutoFlush=true
Format="[%TimeStamp%] [%ThreadID%] <%Severity%> %Message%"
Asynchronous=false
Target="logs"
FileName="logs/quo.%Y%m%dT%H%M%S.%a.%5N.log.detail"
RotationTimePoint="00:00:00"
RotationSize=104857600
MinFreeSpace=4294967296
MaxSize=4294967296
ScanForFiles=All
when date change to next day. my program crash by exception:
terminate called after throwing an instance of
'boost::filesystem::filesystem_error'
what(): boost::filesystem::last_write_time: No such file or directory: "/root/work/hy-trade/bin/debug/logs/quo.20181027T173106.Sat.00000.log.detail"
I check my disk space, find the free space less than MinFreeSpace in config and the file quo.20181027T173106.Sat.00000.log.detail not exists.
how to avoid this exception?
version of boost is 1.67
thank you
It looks like someone had already deleted the log file before it was rotated. It may have been an external process, or Boost.Log.
With Boost.Log, this can happen if you have multiple file sinks that write log files into the same directory, which is also used as the target directory for the rotated files (i.e. the FileName parameter includes the path specified in the Target parameter, and there are multiple sinks that use that path). The problem is because, according to ScanForFiles=All, the library scans the target directory for any files but does not update the file counter to be used for creating new files. This means that if the file "quo.20181027T173106.Sat.00000.log.detail" was present in that directory when your process started then it would be considered as an old file, even if upon starting your process would be still writing new logs to that file. Then, when a file rotation happens and storage limits are exceeded (e.g. if MinFreeSpace is not satisfied), that file may be deleted. The rotation has to happen on another sink that still stores files into the same "logs" directory.
To solve the problem you can do one of the following:
Use ScanForFiles=Matching in your settings so that the file counter is updated after scanning. This will make sure that new log files have unique names and don't get deleted prematurely.
Write log files to a different directory from your target storage. I.e. specify FileName so that it doesn't point to the same directory as Target.
Also, you may want to add exception handling to avoid crashing in case of errors (which may still happen for whatever reason on filesystem operations). See here and here for more info (also, follow the links in those sections).
i when run this test program create the below error.
import shutil
src=r"G:\aaa"
dst=r"F:\zzz"
shutil.copytree(src,dst, symlinks=False, ignore=None)
FileExistsError: [WinError 183] Cannot create a file when that file already exists:
but the the folder of F:\zzz is empty!!!
shutil.copytree(src, dst, symlinks=False, ignore=None, copy_function=copy2, ignore_dangling_symlinks=False, dirs_exist_ok=False)
dirs_exist_ok dictates whether to raise an exception in case dst or any missing parent directory already exists.
Python 3.8 now have support of dirs_exist_ok parameter. This won't give that error anymore and overwrite the destination folder in case it already exists.
Hence you need to use:
shutil.copytree(src, dst, dirs_exist_ok=True)
"Cannot create a file when that file already exists" is a generic Windows message which is confusing because it's the same for directories or regular files. (Windows isn't known for very helpful error messages, you have to make do with that)
from the online help of shutil.copytree:
>>> help(shutil.copytree)
Help on function copytree in module shutil:
copytree(src, dst, symlinks=False, ignore=None, copy_function=, ignore_dangling_symlinks=False)
Recursively copy a directory tree.
The destination directory must not already exist.
So first time it probably works, but other times you need to perform
shutil.rmtree(dst)
to remove the destination directory prior to copying the tree (note that Windows is annoying with permissions and that files with read-only attribute can choke shutil.rmtree, which I personally copied the code into a custom version (you're encouraged to do so in the online help) to add a os.chmod(path,0o777) prior to deleting regular files.
Whenever I add a third config file to my .immuconf.edn I get:
No configuration files were specified, and neither an .immuconf.edn file nor
an IMMUCONF_CFG environment variable was found
This is driving me crazy since I cant really find anything wrong.
Using this loads thing OK:
["configs/betfair.edn" "configs/web-server.edn"]
however this generated an error:
["configs/betfair.edn" "configs/web-server.edn" "~/betfair.edn"]
This is the content of betfair.edn
{:betfair {:usr "..."
:pwd "..."
:app-key "..." ;; key used
:app-key-live "..."
:app-key-test "..."}}
(where ... is replaced with actual strings)
Why am I getting this error when adding the third file and how can I fix this?
Make sure that the last file specified in your <project dir>/.immuconf.edn (~/betfair.edn) exists in your home directory.
Immuconf does some magic to replace ~ in filenames specified in .immuconf.edn with a value of (System/getProperty "user.home") so you might check if that system property points to the same directory where your ~/betfair.edn file is located.
I have recreated your setup and it works on my machine so it is probably a problem with locations or access rights to your files. Unfortunately, error handling for the no arg invocation of (immuconf.config/load) doesn't help in troubleshooting as it swallows any exceptions and returns nil. That exception would probably tell you what kind of error occured (some file not found or some IO error happened). You might want to file a pull request with a patch to log such errors as warnings instead of ignoring them.
I had made a source file data type change in source analyzer. I did realize that it had made the mapping invalid. I ran the mapping and it failed. Now I reverted the change, validated the mapping, check in the mapping, validated the workflow, check in the workflow.
Now I am getting the error:
Severity Timestamp Node Thread Message Code Message
INFO 7/23/2015 10:40:03 AM node01_CSADevelopment READER_1_4_1 FR_3055 Reading input filenames from the indirect file [<input_directory_folder>/<input_file>].
Severity Timestamp Node Thread Message Code Message
ERROR 7/23/2015 10:40:03 AM node01_CSADevelopment READER_1_4_1 FR_3000 Error opening file [<input_file_folder>/<header_of_the_input_file>]. Operating system error message [No such file or directory].
here the term "input file" is the file which I wanted to load and "header_of_the_input_file" is the header of the input file.
I don't understand, why it is happening. I had just made a small change and then reverted it.
The error is just saying the filenames mentioned in the indirect file are not found. So, you just need to make sure all the source files are there in the "input_file_folder"
There is a property in the session to configure the source file as indirect. An indirect file contains a list of source filenames. Informatica reads all the files listed and loads the data. If you think you have inadvertently made the source file indirect, you can change the option in session properties (mapping tab -> Source Qualifier)
It does not have anything to do with the datatype change and reverting it.
I need my program to start a new log file in each execution. I want to use PoCo as I am already using this library in the code.
From my point of view, I have two possibilities but I do not know how to configure any of them using a channel in Poco.
Just starting a new file each time the program starts
The atual file name (not the rolled but the one that is being writting) containing the timestamp when it was created.
If I am not wrong, using FileChannel is not possible any these possibilities. I guess I could write a new PoCo channel but, obviously, I prefer something already working.
Does anybody have any idea for this. I tried to figure out using two channels but I do not see how.
thank you
FileChannel has rotateOnOpen property. If you set this to true, it will create new file every time channel is opened. See FileChannel. If you do not have this property available, you are using an older version of Poco; in this case, you can simply open File channel with a newly generated name every time your application starts:
std::string name = yourCustomNameGenFunc();
AutoPtr<FileChannel> pChannel = new FileChannel(name);
