I am trying to find it if there is any way for sharing the variable between execution groups that are running on the same broker other than Cache node (since its not supported by IBM), DB (since its expensive).
I thought we could do this by using the queue, then later decided not to go with that as it may get into loop if the message not deleted from the queue somehow.
Can you guys please suggest if there is any better way in achieving this?
Thank you!! |

| Yes, and has been discussed ALOT here. Singletons, solidDB, Web Services are a few examples. |
But they're all custom solutions, there isn't an inbuilt solution. |

Hi,
Is it just sharing a variable between Multiple Execution Groups in same Broker? Then we do have a shared variable concept.
Declare a variable as shared one & initialize it. This variable can be used across broker. Also it can be assigned different values from any flow.
These variables will be accessible across broker But each message flow will have a local copy of this variable with certain value corresponding to the message flow.
Is this helpful or did I misunderstood the question itself? |

ESQL Shared variables are only 'shared' within the same EG. They are defined in all EGs that deploy the ESQl code that defines the shared variable, but they have different values in each EG. |
