Testing concurrency

You can use the SQL statements in member DSNTESD to test concurrency within the data sharing group.

Procedure

To test concurrency:

  1. Run SPUFI concurrently on different data sharing members.
    Specify AUTOCOMMIT=YES.

    Global locking ensures that inserts to DSN8C10.PARTS are coordinated across data sharing members.

  2. Verify that ITEM_COUNT increases by five each time the run completes successfully.
