Reports Distribution

Question

Hi,
We have been distributing reports to mutiple destinations for almost six months now without any problems. The volume was low, approximately 2000 pages per day.
Now, the volumes hav increased to 15000 and suddenly the report fails to distributes !! It completes all the activities and then gets stuck at the After Report trigger. After an hour or so, it comes out with a memory error. the second time, it just came out with a null error.
Has anybody faced a similar problem ?
Is there a limit to the number of files that can be created via distribution?
Regards.

Answer 1

I have found the same problem if the report is generated in pdf format;
I only have a simple query for know the memory used for the oc4j:
select count(*)
from all_objects objects2
, all_objects objects1
where rownum < (700 * 80 )
it generates around 56000 records ( near 700 pages with 80 records per page ), and with the use of OC4J for generating only this report, the memory consummed is over 250Mb.
In production environment the next error is presented if many users try to get a generated pdf from reports services:
ORA-29532: Java call terminated by uncaught Java exception: java.lang.OutOfMemoryError
ORA-06512: at "SYS.XMLPARSERCOVER", line 0
ORA-06512: at "SYS.XMLPARSER", line 89
Several memory paramenters of the application server and database session parameters has been adjusted (sga_* / java_*) without any good result for delete this error.
It seems an xml parser error relative to the use of DOM,
but ¿Is Oracle Reports Implementation using DOM as a media to generate the pdf format?
