Fileset-Local – Renaming an output file when finished

[Steve Drozdowski]

Using the fileset-local protocol to move a batch file thru the engine.  When done, I want to rename (and/or move) the outbound file to indicate that it is finished processing.  Anyone have any good ideas about how to do this?

Thanks much!

Steve –

  Whatever value the metadata has for OBFILE will ultimately be the file name.

  Example –

           # The fileset driver’s configuration in NetConfig

           # may be overridden by setting the equivelant key

           # to the desired value in the messaga meta data

           # field DRIVERCTL.

           #

           # Here the name of the outbound field is changed

           # from what is configured in NetConfig to the

           # value supplied by the user by setting file name to

           # the value currently in the variable ‘file_name’.

           set dvr_ctl_str “{FILESET {{OBFILE $file_name}}}”

           msgmetaset $mh DRIVERCTL $dvr_ctl_str

Hi James, thanks for this info.  This might come in handy.

What I am actually trying to do is to create a file in an OB directory with a “.lck” extension (indicating that the file is still being processed), and then when it is all done, rename it without the “.lck” extension.

Any ideas?

Thanks.

You could use a upoc thread, first make sure the OB queue of OB thread and xlt queue of the IB thread are both 0, then another tcl to change the file name. Put the below tcl in the Read TPS inside the UPoC properties.

Hope this helps,

Sam 🙂

break

     }

  }

          if {$ob_q == 0 && $xlt_q == 0} {

      # change the output file name

     

  } else {

      echo “Continue scanning…”

      return “”

  }

Steve,

You could put the procedure that renames the file into the ‘send ok’ tps.  That way you’re guaranteed that the engine has closed the file.

Thanks Greg, I will try that!   😀

Greg will this method only work if the outbound fileset-local “style” is set to EOF?  Currently we are using style NL because the file being processed is very large.  If I switch to EOF, will the entire file (a single big message) be kept in memory until it isa ready to be written out?

Thanks.

If you know you have the last transaction…

Do a msg copy and set the the metadata for the filename of the second message to .done

Have an alert sitting there watching for file change to .done and fire off your script to rename and cleanup.
