The import will probably take longer than a plain export because it is writing. Not only does this require the data to be committed (i.e. to disk, not a query commit) but this will write to redo logs, perhaps extend tables etc. beware that cancelling your loader with do one of two things:-
- Commit an incomplete load (which you might need to tidy up)
- Roll-back, which can also take a long time.
For clarity,
- is this an extraordinarily long delay?
- can you still connect to the database with another session?
It might be that the redo/undo areas are full or if redo logs are moved to disk, the filesystem that holds them might be full. Have a look at the oracle logs to see if that's the case.
The
sqlldr will commit at the end anyway. I think you can use the parameter
ROWS=1000 or a suitable number on
sqlldr to force more regular commits, at which point you can use another session to count the rows imported into your table so far.
Does that help?

nfsiostat(8) System Manager's Manual nfsiostat(8)
NAME
nfsiostat - Emulate iostat for NFS mount points using /proc/self/mountstats
SYNOPSIS
nfsiostat [[<interval>] [<count>]] [<options>][<mount_point>]
DESCRIPTION
The nfsiostat command displays NFS client per-mount statisitics.
<interval>
specifies the amount of time in seconds between each report. The first report contains statistics for the time since each file sys-
tem was mounted. Each subsequent report contains statistics collected during the interval since the previous report.
<count>
If the <count> parameter is specified, the value of <count> determines the number of reports generated at <interval> seconds apart.
if the interval parameter is specified without the <count> parameter, the command generates reports continuously.
<options>
Define below
<mount_point>
If one or more <mount point> names are specified, statistics for only these mount points will be displayed. Otherwise, all NFS
mount points on the client are listed.
OPTIONS
-a or --attr
displays statistics related to the attribute cache
-d or --dir
displays statistics related to directory operations
-h or --help
shows help message and exit
-l LIST or --list=LIST
only print stats for first LIST mount points
-p or --page
displays statistics related to the page cache
-s or --sort
Sort NFS mount points by ops/second
--version
