Long Running Processes

By using AutoScript, in kosmos/BOS suite, we can build software (intelligent agents) that can support long running processes. For example every agent that is specialized as "coordinator" has a capability to keep his "code" running for days or moths. See for example the following "action code" of an agent (from AutoServices demo application).




   call bpm_setprocedureowner(__activation_user)                   {.....set the procedure owner}


  {(1)....any user can put a new service request}


   callwait bpm_assign_job ( "new service request" , __activation_user , "" , 0)


   serv_id = bpm_getrecid(1,__au_step)                   {......get the record id of the service request}

   app_date = LookUp("SERV","SERV",serv_id,"ADATE","")

   customer = LookUp("SERV","SERV",serv_id,"CUSTOMER","")

   car_no = LookUp("SERV","SERV",serv_id,"CAR_NO","")


   comm = strcat(customer," with car ",car_no)

   call bpm_setprocedurecomment(comm)                       {.....set the procedures comment}


  {(2)....at date (app_date) the GATE SECURITY waits the customer to come for the appoinment}


   app_date_num = DateToNum(app_date)

   callwait bpm_assign_job ( "service appointment" , "" , "GATE SECURITY" , app_date_num , erv_id )


  {(3)....the CHIEF MECHANIC makes the first estimation of labor and materials, assigns a mechanic}


   callwait bpm_assign_job ( "service estimation" , "" , "CHIEF MECHANIC" , 0 , serv_id )

   disas_mechanic = LookUp("SERV","SERV",serv_id,"MECHANIC1","")     {....disassemble mechanic}

   reass_mechanic = LookUp("SERV","SERV",serv_id,"MECHANIC2","")     {....reassemble mechanic}


  {split activities....at the same time, the warehouse prepares the materials,}

  {       the mechanic starts working, the cafeteria hosts the cutomer}


   split_in_branch                     {parallel split....the technical department does the job while in...}


      split_in_branch         {parallel split...(4) the warehouse prepares the required parts while ...}


          callwait bpm_assign_job ( "collect parts" , "" , "WAREHOUSE" , 0 , serv_id )


      and_branch               {(5).... the assigned mechanic disassebles the engine}


          callwait bpm_assign_job ( "disassemble" , disas_mechanic , "" , 0 , serv_id )




      {(6).... the assigned mechanic puts the parts and reassebles the engine}


      callwait bpm_assign_job ( "reassemble" , reass_mechanic , "" , 0 , serv_id )


   and_branch                                     {(7).... the cafeteria the customer takes a cofee}


      callwait bpm_assign_job ( "host customer" , "" , "HOSTESS" , 0 , serv_id )


   join_branches               {...the customer finished his/her coffee and the job has been done}


   {(8)....the customer goes to the office in order to pay}


   callwait bpm_assign_job ( "payment and goodbye" , "" , "OFFICE" , 0 , serv_id )




We can shut down the agency server as many times as we wish without loosing the code (agent) any of his process information.
