Hello,

Is there a way to restrict users from being able to submit job that requires a tape mount in os/390 ? The objective is to enable only our operations group to submit jobs that requires tape mounting. Applications group will be prohibited in submitting jobs that will require tape mounting.
We have RACF as our security sw.

I have looked at the racf and tso uads. it seems that you can control tso mount thru the mount attribute in the uads or the racf tso segment (tsoauth, mount attribute). But for jobs submitted by the users , i coudn't find anyway to control this ?

Can anyone provide any suggestion to do this.

You can only do it (I am pretty sure) if you look for a MOUNT message in the wto exit. Then you get to decide if you want to cancel the user or not. This helps only if you have good job naming standards . There *MIGHT* be away if you can get the info from RACFUID

This solution is not that viable since it kicks in AS the job step that requires the tape mount starts to execute. Thus you might have had a number of steps run before you run into trouble. You want a solution that will prevent the job from being initiated in the first place (such as my suggestion to have JES2 parse the converted JCL to spot any tape requests and trigger a JCL error at that point).
