Re: Access a SAVF

[José Luis Calvo <jlcalvo@xxxxxxxxxxxxx>]

The extension .SAVF was a mistake in the e-mail. Sorry.

I was using the correct extension ".FILE" without result.

Yes the IFSFileInputStream work. But the access is by the TCP servers
(as-file i think) and i want to access it in native form ( for performance)

Just now i am copying (CPYTOSTMF, and CPYFROMSTMF) the SAVF to the IFS, and
access it there.

Of course this have the overhead of the copy.

My test was:
        SAVOBJ (to the SAVF)
        CPYTOSTMF ( the SAVF to a stream file in the ifs)
        access the stream file with java InputStream, and create a .zip file
in the IFS

After that i try to regenerate the SAVF with the inverse process and restore
the objects, and it run sucessfully.

But i don't want the overhead of the copy.

Your extension was wrong when using FileInputStream.  It should be .File --
"/QSYS.LIB/OPERA.LIB/TEST.FILE".  I'm not saying you will be able to
open/read the file.  I think you will because the Toolbox
IFSFileInputStream class works, but I didn't write a testcase to verify
open/read.  At least you won't get a file-not-found error.  Green-screen
command wrklnk is a good command to use to verify QSYS object names
accessed via IFS naming conventions.

One other option you have is FTP.  You could FTP the file from QSYS to a
file in IFS using the FTP class in the Toolbox.  I'm not saying this is a
good option for getting data, but it is one that will work.  FTP does have
an advantage when putting.  When you put savefile data via FTP, the iSeries
FTP server does the necessary data manipulation to preserve the file as a
save file.  My experience is when you simply copy over a save file, the
iSeries no longer sees the file as a well formed save file.

I am trying to access a SAVF from a java program running locally in an
AS/400 (iseries), with the following results:

    using FileInputStream: File /QSYS.LIB/OPERA.LIB/TEST.SAVF not found.

    using IFSFileInputStream: the access is by TCP/IP to LOCALHOST

    using jdbc (db2_classes.jar): File TEST in OPERA is not a database file

I just want to know if this is correct.

I like to access natively the SAVF, for better performance.

Do you have any comments?

P.D.: Sorry for my english. I speak spanish.
