Activate Callstack Dump From Server Manager

Server_Manager-Enterprise_Server_Processes

While doing some not-so-fun troubleshooting, we needed to get a callstack dump from a Call Object Kernel that was going into a zombie state. I hate those things!

Anyway, follow the steps below to get a callstack dump from Oracle JD Edwards EnterpriseOne Enterprise Server:

  1. Within the Network and Queue Settings configuration, verify Jdenet_n Signal Handler is enabled.
    Server_Manager-Network_Queue_Settings
  2. Set the Create Kernel Process Dumps to Create Kernel Dumps
    Server_Manager-Network_Queue_Settings2
  3. When a call object kernel crashes (zombie) locate it in Server Manager and open the jde.log.
  4. Scroll down to the bottom and you will see an entry related to a dump file. On a Windows Server, the entry will tell you exactly where the file is located. For Linux and Unix locate the dump file in the same directory as the parent logs files.

Now, the fun part you get to try and figure out what happened.

Do you have any tips when it comes to getting or reading dmp files?
