Hi,
I have created a SQL script containing the command:
host exp user/pwd@db file=dmp/produkt.dmp log=log/ex_produkt.log tables=produkt rows=y grants=n indexes=n constraints=n triggers=n
It works perfectly well, in the log file it sais:
... rows exported
EXP-00091: Exporting questionable statistics.
Export terminated successfully with warnings.
Then I have another SQL script containing the commands:
truncate table owner.produkt;
host imp user/pwd@db file=dmp/produkt.dmp log=log/im_produkt.log tables=produkt ignore=y
This command does load the data in the table, but then the dos box does not close, so my script does not continue until I manually close the dos box. Also, a log file is created but no information is written in it.
If I remove the "ignore=y" option, then the dos box DOES close automatically and in the log file I get the "can't create table ..." error. But that is why the ignore option is invented of course.
Any ideas on what I can do or check to solve this problem?

EXP-00091: Exporting questionable statistics.
means that Export exports statistics that is dated before some changes in the table.
So the stistics is not relevant and need to be updated using DBMS_STATS package.
In fact this is only a warning that possibly the CBO will deal with old statistics
and so the execution plans can not be optimal.
STATISTICS
Default: ALWAYS
Specifies what is done with the database optimizer statistics at import time.
The options are:
ALWAYS
Always import database optimizer statistics regardless of whether or not they are questionable.
NONE
Do not import or recalculate the database optimizer statistics.
SAFE
Import database optimizer statistics only if they are not questionable. If they are questionable, recalculate the optimizer statistics.
RECALCULATE
Do not import the database optimizer statistics. Instead, recalculate them on import.
if you dont want statistics to get imported, then use :
--------------------------
host exp user/pwd@db file=dmp/produkt.dmp log=log/ex_produkt.log tables=produkt rows=y grants=n indexes=n constraints=n triggers=n statistics=SAFE
Thanks
Ok thanks
>simply ensure to update the table statistics regulary on all the tables. command is ANALYZE TABLE <tablename> COMPUTE STATISTICS;
I know what that means, just added the end of the log file so that you could see, that there's nothing wrong with that.
>does it also have the last line EXIT; in the script...
It is an SQL script and I start it from SQL*plus, so I don't think I need that. It really is the "host imp ..." command that hangs.
As I said:
When I remove the ignore option, the dos box IS automatically closed and the logfile shows the error that I expect
Now, I need the ignore option AND I want the dos box to close and the script to proceed after the imp command.
as far as i know, dos screen/window/box will get closed automatically once the import command is over and the next sql command will get executed if any in the sql prompt.
May be if that doesn't work, create a batch file and put this import command in the imp.bat and call host imp.bat and see. You can also include exit as the last line in the imp.bat so that we ask it to close.
I have not tried but you can try i think.
Thanks
That of course didn't do it as well. The dos box disappears, but no data is loaded, I was too quick yesterday. AngelIII you are a lucky man!
So still the same problem: rows are loaded, but no log file and the imp command doesn't seem to end.
If any of you still have any suggestions?
Maybe I'll post the same question again, so that new points can be earned.
