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...
