PH12284: THE DEFAULT CONNECTION MANAGER POOL IS FULL

APAR status

• Closed as fixed if next.

Error description

• When using htds execution with trace enabled you might face a
  blockage where the connection pull gets full.
  It is related to a deadlock that is visible in a threaddump.
  Thread Name : Default Executor-thread-4426
  State : Deadlock/Blocked

Local fix

• there are two workarounds for the issue:
  1) disable rulesetdata warehouse tracing
   2) If  still need the tracing on, you can change the current
  ruleset implementation,
  In BOM, you may use a tester in an extender class, instead of
  an extender implemented in IRL.
  Here is an example of a tester in an extender:
  public class CustomerExtender {
  ......
  // THE TESTER
  public static boolean tester(Map customer) { return
  "Customer".equals(customer.get("className")); }
  }
  The extender has to be declared in the B2X part of the BOM
  class.
