This article explains why the connection to a Connection Manager (CM) through a Connection Manager Master Process (CMMP) can fail if one or more of the CMs from the CMMP pool is down. It answers the question if - beyond its load-sharing feature - it is possible to use CMMP to implement a fail-over mechanism.
Considering a system which CMMP has two connections CM1 and CM2 in its pool; CM1 runs normally and CM2 is in a failed state. One session could run testnap which will only be connected from time to time. The load balance scheme is random :
- sometimes it properly connects to the running CM.
- sometimes it reaches the failed CM and the connection fails.
Statistically, there is a 50% chances to hit the failed CM, 50% chances that the connection properly works.
