In these cases, I have often seen issue with the Network configuration
cause this. Most often, its a DNS server that is not working correctly,
that is causing the code to sit on timeouts...

Subject: JDBC performance issues after moving to Java 8
Date: Fri, Jul 6, 2018 8:01 AM

We have a Java application running on IBM i v7.1. It was working fine
with
Java 6, but when we moved to Java 8 in preparation for an upgrade to
v7.3,
the program started taking over an hour to run. As far as I know, the
only
change was to move to Java 8. We are using the 32 bit JVM for both
Java
6
and Java 8.

Any ideas on where to look for issues? We are not getting any errors
that I
know of, and everything is running through properly. It just takes
over
an
hour for the program to run now when it used to take minutes. The
application is using JDBC to communicate with a MS SQL Server. It is
basically synchronizing data for another process that runs on Windows.
