Has anyone been able to change the attribute of a queue from HARDENBO to NOHARDENBO on UNIX (specifically AIX).
I've been told it is a performance hit if you're using teh BOTHRESH.
Any info is appreciated |

From the Application Programming Reference:
| Quote: |
Hardening information for each MQGET call within a unit of work, however, imposes a performance overhead, and the HardenGetBackout attribute should be set to MQQA_BACKOUT_HARDENED only if it is essential that the count is accurate.
On Compaq OpenVMS Alpha, OS/2, OS/400, Compaq NonStop Kernel, UNIX systems, and Windows, the message backout count is always hardened, regardless of the setting of this attribute.

Since you are Unix, there is no point in you trying to set this value.
Remember, it is only valid for local and model queues.
