So I try
.writemem C:\f.dll 76dd0000 76ec0000
( 76dd0000 ~ 76ec0000 is kernel32.dll's start address and end address )
and I get result from windbg

I imported my excel file into R Environment and saved the path by creating a new file in R scrip. However, when I tried to check my directory and load the dataset, I received the following message " Error: path does not exist: ‘MIS_655_RS_T3_Wholesale_Customers’
What am I doing wrong here?
Thanks
Have you missed the format of your dataset, eg. csv, xlsx.
I suggest you first set your file as working directory, then the following code might help you with it.
Dat_customers <- readxl::read_excel("MIS_655_RS_T3_Wholesale_Customers.xlsx")
When I am trying to read many h5 files in one shoot. There is an OS error states like this:
OSError: Unable to open file (unable to open file: name = '/scratch-lustre/hpc-0227/deepcpgData/c{1,2,3,4,5,7,9,11,13}_*.h5', errno = 2, error message = 'No such file or directory', flags = 0, o_flags = 0)
I am sure all of these files exist and files' name corresponded with c{1,2,3,4,5,7,9,11,13}_*.h5 rightly. I am also using absolute path. My bash script looks like this:
data_dir="/scratch-lustre/hpc-0227/deepcpgData"
train_files="$data_dir/c{1,2,3,4,5,7,9,11,13}_*.h5"
It works when I use the full name of a single file, for example, c16_1572864-1605632.h5. However, I need to read a lot of files. So I have to read them in one round. I have searched many other answers but none of them deal with multiple files and the os error at the same time.
I have the following problem:
I am using the following command:
EXPORT TO "D:\ExportFiles\ACTIVATE_DICT.csv" OF DEL MODIFIED BY TIMESTAMPFORMAT="YYYY/MM/DD HH:MM:SS" STRIPLZEROS MESSAGES "D:\ExportFiles\FMessage.txt" SELECT * FROM DB2INST4.ACTIVATE_DICT;
In the Command Editor of the program, the Control Center successfully exported data from the ACTIVATE_DICT table to a CSV file ACTIVATE_DICT.csv.
But for a number of reasons, I need you to execute this command in the IBM Data Studio or DataGrip program, and there it cannot be executed in this form.
Therefore, I read the following manual enter link description here
and based on it wrote the following command:
CALL SYSPROC.ADMIN_CMD('EXPORT to /lotus/ExportFiles/ACTIVATE_DICT.csv OF DEL MODIFIED BY TIMESTAMPFORMAT="YYYY/MM/DD HH:MM:SS" STRIPLZEROS MESSAGES /lotus/ExportFiles/FMessage.txt SELECT * FROM DB2INST4.ACTIVATE_DICT');
Here is the message on the result of the command:
[2018-10-11 15:15:23] [ ][3107] There is at least one warning
message in the message file.. SQLCODE=3107, SQLSTATE= ,
DRIVER=4.23.42 [2018-10-11 15:15:23] 1 row retrieved starting from 1
in 75 ms (execution: 29 ms, fetching: 46 ms)
And in the / lotus / ExportFiles / directory there is no ACTIVATE_DICT.csv file and there is no FMessage.txt file in the / lotus / ExportFiles / directory.
Question: How then to correctly execute this command ??? Maybe I'm doing something wrong?
sqlcode 3107 is a warning message:
SQL3107W At least one warning message was encountered during LOAD processing.
Explanation
You can load data into a database from a file, tape, or named pipe using the LOAD command. You can specify that any warnings or errors from the LOAD processing be printed to a message file. If no message file is specified, the warnings or errors are printed to standard out (unless the database manager instance is configured as a partitioned-database environment.)
It is to tell you to read message log in the message file you specified. In your case: /lotus/ExportFiles/FMessage.txt
Please read into the file to see what error is logged and if you need help understand what is logged, please post the content of the file.
This message is returned when at least one warning was received during processing. If a message file is being used, the warnings and errors will be printed there.
This warning does not affect processing.
User response
Review the message file warning.
EXPORT command using the ADMIN_CMD procedure
See use of the 'MESSAGES ON SERVER' clause, and how to get these messages using the result set returned by this routine in this case.
I have tables called; quotes, trades and sym saved as splayed tables in a directory called splay in my q directory. I cannot figure out how to load these tables using the methods identified on the code.kx.com website. When I check the file properties, it says file type is File, so I do not know what type of file to open after the filename. Once I have managed to load these files, I need to select all records that contain the symbol IBM (in the column sym of the tables). I have tried so far:
q)\cd splay
q)\l quotes
'quotes. OS reports: The system cannot find the file specified.
[0] (.Q.l)
q)\l trades
'trades. OS reports: The system cannot find the file specified.
[0] (.Q.l)
.Q )\l trades.q
'trades.q. OS reports: The system cannot find the file specified.
[2] (<load>)
))\l trades.dat
'trades.dat. OS reports: The system cannot find the file specified.
[4] (.Q.l)
to no avail. the same approach but for the directory itself.
q)\l splay
I have tried to just run the files without loading by being in the directory but this has also not been successful.
q)\cd splay
q)\cd
"C:\\Users\\Lewis\\splay"
q)t:get`:trades
'trades. OS reports: The system cannot find the file specified.
[0] t:get`:trades
^
q)q:get `:quotes
'quotes. OS reports: The system cannot find the file specified.
[0] q:get `:quotes
^
q)load`quotes
'quotes. OS reports: The system cannot find the file specified.
[0] load`quotes
^
One of the ways the code.kx.com website says to do this, and one of my first approaches:
C:\Users\Lewis\q>q/q.exe splay
KDB+ 3.5 2017.10.11 Copyright (C) 1993-2017 Kx Systems

To exit, type \\
To remove this startup msg, edit q.q
'/q.exe. OS reports: The system cannot find the file specified.
[0] (.Q.l)
.Q )
and the final approach I have had to load these files or directory is:
q)))load `splay
'splay. OS reports: Access is denied.
[6] load `splay
^
q))))\cd splay
q))))load `splay
'splay. OS reports: Access is denied.
[9] load `splay
^
Please, help me!
If you are in the directory /Users/Lewis you should be able to pass the splay as a command line parameter, like this: q splay. There may be an issue with the path you are using to your q application q\q.exe which is causing an error to flag up.
Alternatively you should be able to open it from inside an active q session like: \l splay provided you are in the directory /Users/Lewis OR like \l . if you are in the directory /Users/Lewis/splay, where . is a shortcut for the current directory.
Additionally you stated that you have the tables trade, quote and sym. It all depends how you saved the data to disk but the sym file should not be a table like the other two, which you should see when you load the data in.
The error OS reports: Access is denied. is probably due to the q process not having appropriate permissions to access the file. If you start the process with admin privileges you should be able to get around this error.
In isql-vt (the Ubuntu name for Virtuoso's isql), I am trying to import a test .ttl file, but get the error "Can't stat file":
SQL> DB.DBA.TTLP(file_to_string_output('./scratch/ttl/granule.ttl'),'','http://origin.mytest.org/');
*** Error 42000: [Virtuoso Driver][Virtuoso Server]FA112: Can't stat file './scratch/ttl/granule.ttl', error (2) : No such file or directory
However, the file is definitely there; I can even cat it:
SQL> !cat ./scratch/ttl/granule.ttl;
#prefix datacite: <http://purl.org/spar/datacite/> .
#prefix prov: <http://www.w3.org/ns/prov#> .
<http://0.0.0.0:3000/granule/MOD09.A2016278.0110.006.2016279074214.hdf>
datacite:identifier "MOD09.A2016278.0110.006.2016279074214.hdf";
prov:wasGeneratedBy <http://0.0.0.0:3000/run/MODAPS_456056327>;
a prov:entity .
SQL>
Why is the DB.DBA.TTLP command saying it can't stat it?
Trying to use the full path gave a much better error message:
SQL> DB.DBA.TTLP(file_to_string_output('/home/ubuntu/Origin/scratch/ttl/granule.ttl'),'','http://origin.nasa.gov/');
*** Error 42000: [Virtuoso Driver][Virtuoso Server]FA003: Access to
'/home/ubuntu/Origin/scratch/ttl/granule.ttl' is denied due to access control in ini file
So, the solution was to add the path in /etc/virtuoso-opensource-6.1/virtuoso.ini, eg:
...
DirsAllowed = ., /usr/share/virtuoso-opensource-6.1/vad, /home/ubuntu/Origin
...
and restart virtuoso for the change to take effect.
