Hi Guys,
I declared Shared Variables in one of my flow. The flow fetch the values from DB and assign values to those shared variables.
My another flow need to get those shared variables , But It gets only declared values like
DECLARE flg SHARED BOOLEAN FALSE.
My First flow assign a value to flg as TRUE. But My Second flow is it receives only FALSE.
Can one suggest me how i need to read those assigned values. |

It says more than that.
Among other things, it talks about a difference between Module and Schema scope.
It also should explicitly state that you can't share variables between two flows. |

RMI to a static variable with synchronized methods residing in a single JVM... would be one way of doing it...
Have fun

Would suggest something simple like reading the contents of the variable from a shared file, or maybe a database table if you happen to have one.
Of course, this has many impacts and drawbacks, including synchronization, performance, etc. which may or may not be relevant depending on what you're doing. But without further information it's hard to make recommendations. |
