DEBUG (Create Client Trace and Control Display of Server Subcommands Sent to Remote System)

Only use the FTP client trace to report software problems to IBM. System performance might be affected by this function.

FTP client subcommand

The DEBUG FTP client subcommand produces an FTP client trace or display. The DEBUG subcommand toggles the debugging mode. If the client specifies an optional debug-value, it will use it to set the debugging level. When debugging is on, the client displays with the string '>>>'. You must set the debug-value to 100 to produce an FTP client trace.

DEBug [debug value]

debug value: If the debug-value is 0, debugging is off. If the debug-value is a positive integer, debugging is on. If you don't specify a value, the debug value toggles from zero to one or from a positive integer to zero.
100: Initiate an FTP client trace. The client continues running the trace until the DEBUG is off or until the FTP server ends the FTP client. When the FTP server ends the trace, there might be a significant delay while it is formatting the trace data.

To initiate a trace immediately when the FTP client starts, you need to create the QTMFTPD100 data area in the QTEMP library by using this command:

CRTDTAARA DTAARA(QTEMP/QTMFTPD100) TYPE(*LGL) AUT(*USE)

If the QTMFTPD100 data area exists, then it will set the debug value to 100 and start an FTP client trace. The purpose of this capability is to enable the FTP client debug traces in those situations when an FTP client trace cannot start with the DEBUG 100 subcommand.
