Hi, You can write a similar implementation of qlicserver. I have with used below method to integrate FlexLM.
1] Get total available license tokens from license server "lic_total" 2] Get total utilized license tokens form license server "lic_used" 3] Calculate available licenses lic_avail=lic_total-lic_used The change will be in next step where one needs to get resource value from only those jobs which are in* running state.* 4] Get the list of running jobs. 5] calculate number tokens that are currently utilized for above running jobs. "lic_used_in_ge" 6] calculate update value update_value="lic_avail + lic_used_in_ge" 7] use qconf to update the global complex resource value = update_value 8] Repeat from step 1. With this the complex resources utilized by suspended jobs won't be considered and your jobs will be released from queued status. I hope this help.
