RE: Problem running a report

If the report was creating a large output file on the client (remote) PC, that would explain
the waits on SQL*Net message from client. [the client would be SQL*Plus or Reports
on the PC]. Depending on the network latency, the perceived runtime of the report
can vary between sites.
Does the report file have to be created on the client PCs ? Can you run it as a server process, ZIP the output file on the server and then FTP it
to the clients ?

If the report has to run from the PC, try tuning SQLNet (SDU, TDU) and the Buffer size.
If you are using SQL*Plus, just doing a SET TERMOUT OFF with a SPOOL <myoutputfile>
will make a big difference.

Thanks to everyone who responded. The database is centralized. Yesterday I PINGed some machines in different offices (and TRACERTed, too) right from the server, and the response time was under 100 msec. However, some offices reported it to have run normally. That particular report creates a big file on C: (local machine) which raises the question if the machine had enough space on that drive and how fragmented it was... Oh, users.... Best regards to everyone,
Sergey

Are you using remote connections to a centralized database, or does each office have its own database?

Tracert and netstat commands should help you figure out if its a network issue.

Hi, ladies and gentlemen,
Here is a good one. We have 25 offices nation wide, running similar reports. At the headquarters the one in consideration takes 12 min to complete. Any other office (WAN) it gets stuck and takes a few hours if it completes at all. Here is the output from V$SESSION_WAIT for the session:

  SID       SEQ#  EVENT                      P1TEXT             P1  P1RAW
P2TEXT             P2  P2RAW     P3TEXT             P3  P3RAW     WAIT_TIME
SEC_WT STATE
----- --------- ------------------------- ---------- ---------
  SID       SEQ#  EVENT                      P1TEXT             P1  P1RAW
P2TEXT             P2  P2RAW     P3TEXT             P3  P3RAW     WAIT_TIME
SEC_WT STATE
----- --------- ------------------------- ---------- ---------
and so on.(SEQ# increases and then resets).

At the headquarters (LAN) it shows the same event after scattered read and it is done. Could that be a SQL*Net issue between LAN and WAN? Any ideas are appreciated as always.
TIA,
Sergey
