Dear oracle-l'ers, I am stuck in chains here... ;-) What already works is calling a program from a job, passing an argument to the program. So far, so good. What I'm *trying* to do is to run a Scheduler Chain, where one of its steps start the said program. Now, when I create a job to run the chain, I cannot add an argument value anymore with DBMS_SCHEDULER.SET_JOB_ARGUMENT_VALUE because this throws an ora-27475. Any ideas, anyone? I'm on 11.2.0.2, but this question was asked before for 10g and never answered: //www.freelists.org/post/oracle-l/parametrized-programs-in-chains-in-10g,2 Kind regards, Uwe -- //www.freelists.org/webpage/oracle-l
