Shared Graphs update time

Hello guys,

We are curently running ALM QC 11.51 and we have a request to lower the updated data from shared graphs to 30 minutes.

I have modified in site configuration the parameter GRAPH_RESULTS_LIFESPAN to 30 and even 5 but the data is still beeing refreshed at 60 minutes intervals. I also restarted the service with no luck.

Please help

Thank you,

Dorin
