Hi,
I need to implent in Message Broker 8 some kind of subflow semaphore control.
I’ve two message flows that use the same subflow (subf1), till now all ok.
Exist any way to put/create/configure any kind of semaphore to:
When the msgf1 > subf1 > msgf1 is processing the call of the subf1 from msgf2 (msgf2 > subf1 > msgf2) must wait until the 1st subf1 ends.
msgf1 > subf1 > msgf1
msgf1 > subf1 > msgf1
The only way is implementing semaphore using global variables?
Best regads,
Gama |

I am too sure that I have completely understood your problem statement but if you're looking for some parallel processing and need to avoid dead locks while doing that using some shared resources, need to take care of wait and signal mechanism.
The bigger question is if you could use global variables or global chache or other mechanism to achieve it.

Hi,
Yes I need for the subf1 does not work in parallel from other message flows.
Is that possible?
Best regards, |

If you use something (like the global cache) that is a singular storage item and is available to all of the flow instances no matter where they're running.
