Dear all,

We HISP Vietnam team meet a problem and need solution to solve. Currently
DHIS2 of HISP Vietnam using report module to generate reports which created
by BIRT report designer. On the March 19th, 2009 there was a training class
for users to practice entering data and generating reports. The class
includes 40 users work at same time in the program.
Entering data values was fine. But when there are many users generate
reports at the same time. The system suddenly become very slow and every
user get the OutOfMemorry java exception when click in any button of the
program. That time Tri has to restart the tomcat of server, the sistuation
become better for 2 minutes, and the problem appear again when few users
generate reports. This even affect to another users who doesn't generate
report but entering data in the class that time.
Tri has checked in database, there were many many transactions opened but
weren't closed.
After meeting to find the reason, we don't know about other reason except
reports were designed by BIRT. May be we were wrong. We are looking forward
your suggestions and consult to find out the right reason and solutions to
solve. May be change another tool instead of BIRT, or correct the program or
someway else. Dr. Trung requested us have to find the right solution before
April.
Please help us...
