hi,
working with export i have faced some problems.

i have written a stored procedure which will execute os command.

with this procedure i want to execute the following exp command:

exp xxx/xxx@xxx FILE="xx.dmp" LOG="xx.log" OWNER=xx DIRECT=Y statistics=NONE CONSISTENT=Y

it works fine.

but problem is that it takes too much time to complete as compare with executing normal shell exp command(provided above).

what is the problem?
plz help me.
thanks

I think this is an overkill for a simple export job.
If you are calling it from pl/sql using PRO*C or JAVA, there is this unwanted overhead (which is little in many cases).
>>takes too much time to complete as compare with executing normal shell exp
Is that a consitent case? Did try both the options in the exact load conditions?
>> OWNER=xx
Is the stored procedure in the same schema as the OWNER?
>>DIRECT=Y
Idea of DIRECT=y is to bypass the SQL Engines.
If you call it from pl/sql, it may be defying the parameter.
I am not sure about this. Will have to set up a test case.

Regards~

yes i am calling it from pl/sql using JAVA.

i have not tried with consistent=N. now i am checking it.
no, the same problem with the option consistent=N.
the problem is that it halts a long time at some position.i am watching the progress with the log file.on the log file, suppose,at size 3853 there is no progress,it halts a long time.

Is the stored procedure in the same schema as the OWNER?
yes

should i exclude direct option?

thanks

Consistent=n has nothing to do with this.
>>should i exclude direct option?
Try it~.
