In DB2, there is this command that shows active EDUs (engine dispatchable units):
There are two fields in the respective output:
EDU ID and
According to this db2pd page from the DB2 knowledge center, each is defined as follows:
EDU ID: The unique identifier for the engine dispatchable unit (EDU). Except on Linux operating systems, the EDU ID is mapped to the thread ID. On Linux operating system the EDU ID is a DB2 generated unique identifier
TID: Thread identifier. Except on Linux operating systems, the thread ID is the unique identifier for the specific thread. On Linux operating systems, this is a DB2 generated unique identifier
I wanted to know what is considered EDU or thread on a Linux/Unix operating system? Are they the same? What is the difference?
