Hi Group,
A Short Story:
We recently had a problem of not able to upload a file having 40K
number of records from our WebObjects application to the database. We
used to get java.lang.OutOfMemoryError after uploading around 25K
number of records. Alas! this errors should not occur... we gave a -
Xmx of 500m as the VM arg, but even then, there was no luck in
defeating this error.
Then, we thoroughly analyzed the Upload program and fixed the memory
leak.
We were actually invoking "System.gc()" for every 100 records of
upload and this statement is indeed executed successfully ;-) But,
even after that, the unused memory is not freed and leading to
java.lang.OutOfMemoryError .
Now we are able to upload around 70K number of records successfully
without java.lang.OutOfMemoryError .
What actually we did to solve the above problem was, we disposed the
editingcontext frequently and then invoke gc and thatz the 70K number
of records started uploading camly.....
Issue:
Now, the problem we have is, it is taking around 2-3 hours to upload
70K number of records to the database using our WebObjects
application, we would like to complete this upload with in half-an-
hour or better... hope this is possible, NOT joking. So, can any
please advise a Java/WebObjects solution to achieve this target. We
use Java 1.4.2 and WO 5.2.4
Looking forward to your help.
Thanks & Rgds,
Shravan Kumar.M
