I have an application where i am using database connection through Driver Manager i.e. i am not using any Connection pool.
The application performs database operation like selecting data from a table and then update another table .
This program run randomly undergo following error :-
java.sql.SQLException: Connection reset by peer: JVM_recv in socket input stream read

In order to solve it i have taken the following actions
(a) I used the connection pool using Weblogic 7.0.
When i run the program it gave me the following error :
"out of Memory Error"

Hence i increased the heap size of Weblogic 7.0 by updating the
startWLS.cmd .
Here i updated the following variable :
set MEM_ARGS=-Xms512m -Xmx512m

But after implementing this it is still giving me the "out of Memory Error"

I know again switched back with my origanal code that is Connecting through Driver manager.

Can anaybody help me and suggest how can i resolve this problem.
thanks in advance.

Thanks for the reply.

But if the Statement is closed anywhere how the program works properly most of the time.I mean to say if i excute this program for 10 times it works fine for 8 times .Infact in the development environment it has never failed .It is happening only in production server.

Kumar,
An "OutOfMemoryError" usually indicates a memory leak in your application. The usual way to locate the cause of a memory leak is to use a profiler. For your information, the JavaPerformanceTuning Web site has a lot of information on profilers for java applications.

Good Luck,
Avi.
