I want to export a database file that is created through a query, from the AS400 machine to my pc in the form of a csv file.
Is there a way to create that connection of the AS400 and my pc through a cl program?
An idea of what I want to do can be derived from the following code:
CLRPFM DTABASENAME
RUNQRY QRY(QRYTEST1)
CHGVAR VAR(&PATH) VALUE('C:\TESTS')
CHGVAR VAR(&PATH1) VALUE('C:\TESTS')
CHGVAR VAR(&CMD) VALUE(%TRIM(&PATH) *CAT '/DTABASENAME.CSV' !> &PATH !> &PATH1)
STRPCO PCTA(*YES)
STRPCCMD PCCMD(&CMD) PAUSE(*YES)
where I somehow get my database file, give the path that I want it to be saved in, in my pc , and lastly run the pc command accordingly
Take a look at
Copy From Query File (CPYFRMQRYF)
Which will allow you to create a database physical file from the query.
You may also want to look at
Copy To Import File (CPYTOIMPF)
Which will copy data from a database physical file to an Integrated File System (IFS) stream file (such as .CSV); which are the type of files you'd find on a PC.
ex:
CPYTOIMPF FROMFILE(MYLIB/MYPF) TOSTMF('/home/myuser/DTABASENAME.CSV') RCDDLM(*CRLF) DTAFMT(*DLM) STRDLM(*DBLQUOTE) STRESCCHR(*STRDLM) RMVBLANK(*TRAILING)
FLDDLM(',')
However, there's no single command to transfer data to your PC. Well technically, I suppose that's not true. If you configure a (SMB or NFS) file share on your PC and configure the IBM SMB or NFS client; you could in fact CPYTOIMPF directly to that file share or use the Copy Object (CPY) command to copy from the IFS to the network share.
If your PC has an FTP server available, you could send the data via the IBM i's FTP client. Similarly, if you have a SSH server on your PC, OpenSSL is available via PASE and SFTP or SCP could be used. You could also email the file from the i.
Instead of trying to send the file to your PC from the i. An easier solution would be to kick off a process on the PC that runs the download. My preference would be a Access Client Solution (ACS) data transfer.
You configure and save (as a .dtfx file) the transfer
Then you can kick it off with a
STRPCCMD cmd('java -jar C:\ACS\acsbundle.jar /plugin=download C:\testacs.dtfx')
More detailed information can be found in the Automating ACS Data Transfer document
The ACS download compoent is SQL based, so you could probably remove the need to use Query/400 at all
Assuming that you have your IFS QNTC mapped to your network domain. You could use the command CPYTOIMPF to copy the data directly from an IBMI DB2 file to a network directory.
This sample would result in a CSV file.
CPYTOIMPF FROMFILE(file) TOSTMF('//QNTC/servername or ip/path/filename.csv') STMFCCSID(*PCASCII) RCDDLM(*CRLF) STRDLM(*NONE)
Use the FLDDLM(';') option in addition to make semicolon separated values, omit it to use comma as value separator.

I am trying to export the data of a table on AS400 to another machine through iSeries commands but I am stacked in the middle of the process. I have a stored procedure in which I create the CSV file but after completion I need to transfer this file to another machine (which is of course connected to the AS400).
In the stored procedure, I used the CPYTOIMPF command to export table data to CSV and I wrote the file on the AS400 file system. I don't know if there is an option to write the file directly to another machine.
CALL QSYS2.QCMDEXC(
'CPYTOIMPF FROMFILE(LIBRARY/TABLE) TOSTMF('/QIBM/UserData/TestFolder/2.CSV') STMFCODPAG(*PCASCII) RCDDLM(*CRLF)'
);
This step is completed and the file is written on that directory.
Now I need to transfer this file to a web server that is connected to AS400 without after the above command is completed.
How can I do that?
You can use FTP on IBM i. Here is a modified example from the IBM Knowledge Center
This is a CL program
PGM
OVRDBF FILE(INPUT) TOFILE(MYLIB/QCLSRC) MBR(FTPCMDS)
OVRDBF FILE(OUTPUT) TOFILE(MYLIB/QCLSRC) MBR(OUT)
FTP RMTSYS(SYSxxx)
ENDPGM
This program overrides the input of the FTP client to a script in MYLIB/QCLSRC member FTPCMDS, and the output of the FTP client to MYLIB/QCLSRC member OUT. The first line of the script must contain the userid and password for the remote location.
Here is a sample script from the same Knowledge Center reference:
ITSO ITSO <== This is the user id and password
CD ITSOLIB1
SYSCMD CHGCURLIB ITSOLIB2
GET QCLSRC.BATCHFTP QCLSRC.BATCHFTP (REPLACE
QUIT
This should not be used outside your network as the user id an password are sent in plain text. It also can be a security risk as production user id's and passwords must be stored in plain text in the source file.
In addition, Scott Klement has a presentation on how to use ssh, scp, and sftp on IBM i. This is quite a long thing, so you might want to read about it here.
A short summary is that scp might be the easiest way to go. but you will need to:
Make sure that OpenSSH option of the OS is installed.
Make sure your Windows server is set up as an ssh server.
Set up a digital key to use for the transfer. Private key goes on client side, and public key goes on server side.
Use scp fromfile user#host:tofile in Pase to transfer the file.
I have done a lot of research on the file types of tableau but I would still like to know more about some file extensions
What is the relation between twbx and tdsx?
Is twbx file : twb + tde file OR twb+tde+tds file ?
What would be the main difference between tds and tdsx file ?
How to use a tps(preferences) file in tableau workbook?
can all the file extensions be used on server or only some ?
twbx contains the workbook including a copy of all the data that you connected your workbook to, while a tdsx contains connection information to remote data sources (Server IPs, tables, etc) as well as any local data that somebody else wouldn't have access to otherwise (eg. an Excel file on your computer). No dashboards are involved. https://onlinehelp.tableau.com/current/pro/desktop/en-us/export_connection.html
A twbx is a twb with a tde file if you want. Remote and local data is stored within your workbook so that other people can access it https://onlinehelp.tableau.com/current/pro/desktop/en-us/save_savework_packagedworkbooks.html
a tds only includes references to data sources but no actual data, so if you connect to a local excel file and it is not accessible via a network, a colleague of yours won't be able to use this file to get the data. A tdsx includes these datasets so you can share it. https://onlinehelp.tableau.com/current/pro/desktop/en-us/export_connection.html
A tps contains custom colour palettes, how you can use it can be found here: https://onlinehelp.tableau.com/current/pro/desktop/en-us/formatting_create_custom_colors.html
Generally all files that you can connect to with Tableau Desktop can be accessed via the server (assuming that the server can access them, ie. the files or sources are on the network). You might however be required to install additional drivers on the server to access for example SAP BW. These drivers are not contained in the default installation.
I have a .twb file created using the excel data source that is located in some network file path.
On publishing to server I get this error.
How to resolve this?
I need to provide some access for "Run as user" in my server machine,how could I do that ?
Ensure that when the workbook is created, a connection to the Excel file is created using the full UNC path
Ensure that the Tableau Server Run As user is able to access that file using the UNC path specified in the workbook. An easy way to test this would be to open Windows Explorer as the Run As user, then paste in the UNC path. If the Excel file opens, then you're good to go.
If you still have issues, test access to the file while logged into the Tableau server to make sure there is no firewall or port blocking access from that host. Often Excel isn't installed on servers for security reasons, so the test is not whether Excel opens the file, but whether you can view the contents from the server as the Run As User, even just using the type command at the console.
If you can't get your network access fixed, an alternative is to build and publish extracts to the server. There are multiple ways to accomplish that
i'm trying to run an exe from a sql job.
the db is on the server, as well as the exe file.
the exe is supposed to write stuff on a log.
even though the sql job is successful, i see no change on the log file.
i've checked the exe locally, and it does work.
The job runs on type cmdexec, and the command is :
\\ustlvint02\c\FixProjectsWhichFailedSync\FixProjectsWhichFailedSync.exe
ustlvint02 - the server's name.
the path is valid, since i tested it by running it from my computer (and there, the log isn't created as well).
i'll appreciate any help you can offer.

The account that SQL Server Agent runs on needs to have permissions to 1.) un the exe in that location and 2.) write to the log file location.
Find out account is used by SQL Agent, then verify that this user has the proper execute and write permissions.
Look for the log file in %WINDIR%\System32 (for 32-bit version of SQL Server) or in %WINDIR%\SysWOW64 (for 64-bit version of SQL Server), where %WINDIR% is a path to the folder where Windows is installed (typically, C:\Windows). This destination does not depend on the system account specified for the SQL Agent job. All files which your executable needs to write to or read from must be either specified within an absolute path or be specified within a relative path and thus be present in the aforementioned system folder.
I've wrote the code that creates full backups of my ESENT database, using JetBeginExternalBackup API.
Following the MSDN guidelines, I backed up every file returned by JetGetAttachInfo and JetGetLogInfo.
I've made the backup, erased old database, and copied the backup data to the database folder.
The DB engine was unable to start, the JetInit error code is "JET_errMissingLogFile".
I've checked the backup, it only contains the database file, and "<inst>XXXXX.log" log files. It lacks the current log file (I'm using circular logging, BTW).
Is there any way to restore such backup?
I don't want to use JetExternalRestore API because it's too complex: I don't need to restore to another location, I don't understand why there're 3 input folders not 2, and I don't know the values to supply in genLow and genHigh arguments.
I do need external backups: the ESENT database is used by ASP.NET on a remote server, and I'm backing it up over the Internet.
Or, maybe there's a way to retrieve the name of the current log file, and I should just add it to the backup?
Thanks in advance!
P.S. I've got no permissions to span processes on my web server, so using eseutil.exe is not an option.
Unpack all backed up files to a single folder.
Take the name of your main database file. Replace extension to .pat. Create zero-length file with that name, e.g. database.pat.
After this simple step, call JetRestoreInstance API, it will restore the backup from that folder.
