I have had OOM, when there was too much of data being retrieved by Ibatis.
with 2000+ statements, I see that as one of the possibility. My heap was
holding up for X amount of data, and I had a hack to loop it when more than
X was there. Increasing the heap helped me too.

Try to increase java heap space by using -Xmx option.

Hi,
I have ~2000 statements spread over a few hundreds of sqlmap.xml
As soon as I init the SqlMapClient I get:
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

(including you) have successfully made it with
large amounts of data (I'm new to iBatis and Compass/Lucene) so I'm
sure there's a solution.

results of a query and, so, index them. The query is just a "select * from
articles_table".
So I wired everything up and ran several tests with different amounts of data
to be indexed and JVM stack space sizes. The result was an "OutOfMemoryError:
java heap space" error me

Yeah, I just noticed that - it looks like it's failing in the jdbc
driver when it tries to read a blob
BC driver is failing when executing the query.

Sure. Please, see attached.
I don't think the problem is in the RowHandler, though, because the
OutOfMemoryError occurs before invoking RowHandle#handleRow.

this is only my 2 cents but I would throw that class out. Write your own
implementation which uses a row handler. This is the type of situation in
which a row

So iBatis does't have any sort of pagination mechanism to avoid filling up the
heap in this sort of situations?
In such case I should try to implement my own pagination or try to use
Hibernate only for this purpose.

Hi, everybody.
I'm testing the Compass search engine and, in particular, how to index a big
set of documents from a table in a MySQL database. In order to do this I issue
a "select * from table_name" using iBatis, but this seems to be causing the
application to use all heap space available.
