In addition to the SHUTDOWN command, it is also possible to use the CANCEL command to shut down a TDP. For example, to cancel a TDP named TDP1, use the following command:
CANCEL TDP1
The effect of this command is similar to that of the Cancel form of the SHUTDOWN command.
When shutting down a TDP, you can use the CANCEL command to generate a dump. For example, to cancel TDP1 and generate a dump, use the following command:
CANCEL TDP1,DUMP
Using PC IACMODE on z/OS SP release 4.3 or later always produces the following message when TDP is shut down:
IEF352I ADDRESS SPACE UNAVAILABLE
This is a normal result of z/OS requirements when using a system linkage index. It does not indicate an error in either TDP or z/OS.
