Mandar, did you have enough disk available for the export file?  You don't say anything about checking your filesystem.

Hi All,

Oracle 8.1.6.1 NT 4 SP5

I'm facing a problem with all exports hanging on our production database. Tried it several times, but the export seems to get stuck at different points each time. The strange part is that at this point v$session_event shows absolutely nothing happening - all the wait numbers just freeze indefinitely and v$session_wait shows a 'SQL*Net message from client' wait - the session seems to be doing nothing at all. This is the output from v$session_event for my latest try

SID       EVENT                                  TOTAL_WAITS  TOTAL_TIMEOUTS
63         latch free                                2                      2
63         db file sequential read             178                   0
63         db file scattered read               6195                 0 
63         file open                                 3                      0
63         SQL*Net message to client      244859             0  

63         SQL*Net more data to client    149282              0  63         SQL*Net message from client  244858              0

I'm running this on the server itself, so the network's not an issue. Tried different export modes and parameters (full, owner, tables, buffer, direct, etc.) but with the same result. I'm pretty new to this site, but I'm told that this problem's been there for some time now but was never really taken seriously since we don't take regular exports.

I'm about to raise a TAR on this one, but any pointers before that would be useful.

TIA, Mandar.
