What to do next
For Windows, if you have started Sterling B2B Integrator as a Windows service,
use the stacktrace tool to take a thread dump. Follow the same procedure to
perform a thread dump for container JVMs.
For more information, refer to the following Web site: http://www.adaptj.com/
main/stacktrace.
You can use VisualVM in remote mode to take a thread dump on Windows when
you start Sterling B2B Integrator noapp or container in service mode.
Refer to the corresponding VisualVM documentation for information about remote
monitoring of JVM, which is available in the following Web site:
https://visualvm.dev.java.net/
HotSpot Thread Dump Analysis Tools
Following is a list of tools that can be used to analyze thread dumps:
v Thread Dump Analyzer (TDA): (Refer to https://tda.dev.java.net/)
Note: In order to use TDA, you must strip off any starting “< “ symbols in the
thread dump if you are using Sterling B2B Integrator UI to take thread dumps.
v You can also use VisualVM for live monitoring of threads in JVM. (Refer to
https://visualvm.dev.java.net/)
HotSpot JVM DeadLock Detection
In addition to the thread stacks, the Ctrl+Break handler executes a deadlock
detection algorithm. If any deadlocks are detected, it prints additional information
after the thread dump on each deadlocked thread.
Found one Java-level deadlock:
