Shared connection usage notes
- Any object handles (Hobj) created by opening an object are associated
with an Hconn; so for a shared Hconn, the Hobjs are also shared and usable
by any thread using the Hconn. Similarly, any unit of work started under an
Hconn is associated with that Hconn; so this too is shared across threads
with the shared Hconn.
- Any thread can call MQDISC to disconnect a shared
Hconn, not just the thread that called the corresponding MQCONNX. The MQDISC
terminates the Hconn making it unavailable to all threads.
- A single thread can use multiple shared Hconns serially, for example use
MQPUT to put one message under one shared Hconn then put another message using
another shared Hconn, with each operation being under a different local unit
of work.
- Shared Hconns cannot be used within a global unit of work.
