Using the EXEC command, you can execute only EXECs on the CA VM:Schedule service virtual machine. The EXECs run under CMS subset and should be very short, because the server cannot process any other work while the EXECs run.
You cannot run EXECs that modify user storage on the CA VM:Schedule service virtual machine. If an EXEC contains CA VM:Schedule commands, the commands must be preceded by CP SMSG *, not VMSCHED. For example, to schedule an EXEC called WEEKRPT at 11:00, enter the following command:
cp smsg * exec weekrpt weekrpt (at 11:00:00
When an EXEC runs on an operational CA VM:Schedule system, the server stacks the user ID that scheduled the EXEC and then invokes the EXEC with its parameters. If an EXEC running on the CA VM:Schedule service virtual machine must use the stack, a read of the first stacked line or a DESBUF must be performed at the start of the EXEC.
Important! Do not use the CMS WAKEUP command in EXECs that run on the CA VM:Schedule service virtual machine. Using WAKEUP can impact the ability of the product to operate and run scheduled requests. Any program that intercepts timer interrupts has the potential of impacting CA VM:Schedule’s ability to operate correctly.
To find out more about EXECs that run on the CA VM:Schedule service virtual machine, contact your system administrator.
