Transfer log and archivefile hang.

[Adoer73]

Currently I'm trying to test synchronize between Primary and Standby Server.
I'm using Windows 2000 and Oracle 10g. I have Installed Dbvisit Standby, configure, create standby database.

But when I type command : Dbvisit Standby [Oracle_SID] on Primary Server, the process will come up, but never end, it;s look like hang, I think it should close the window form after log and archive file are transfered to standby server.

Here's the log process :

C:\>DBVISIT IBS
