Dumping jobs to tape in server mode
The following example shows how to dump jobs to tape when dump job is in server mode. The first thing that needs to be done is to *CALL the dump job DSP; then a standard labeled tape is created on device 560. Because device 560 is defined as a JES3 managed device, it must be varied online as an execution device to the global processor (SY1).
*V,560,ON,SY1
IAT8180 0560 VARIED ONLINE TO JES3 ON SY1
*X,DJ,OUT=560,LABEL=SL,SERVER=YES
Instead of using a specific device, a generic or esoteric device
name could have been specified on the *CALL command. In this case,
the device name must be enclosed in parentheses:
*X,DJ,OUT=(3490),LABEL=SL,SERVER=YES
or
*X,DJ,OUT=(LDE10435),SERVER=YES
As a result of the *CALL command, a dump job server address space
is started. The dump job server address space initializes and allocates
the tape device. The tape device is allocated with deferred mounting
so you will not see any IAT5210 messages asking the operator to mount
the tape if this is a JES3 managed device. A mount message (IEC501A)
will be issued when a *START,DJ command is issued and the tape data
set is opened.

The job name of the dump job server address space is DJ followed
by the job number of the DJ DSP that started the server address space.
To display information about the dump job server address space, issue
one of the following commands:
D A,DJ* or D A,DJ000033

After the dump job server address space has successfully initialized,
dump job issues the messages below to show that it is ready to begin
dumping jobs to tape. Message IAT7272 contains the name
of the tape data set that will contain the jobs that are dumped to
tape. This data set name must be specified on the *CALL,DJ command
when you restore the jobs from tape.
IAT7272 DJ0560 (JOB00033): OUTDSN=JES3.DJ.D1998091.T163039

*IAT7228 ISSUE START OR CANCEL FOR DJ (JOB00033) (0560)
The data set name that is generated is different for standard label
tapes versus unlabeled tapes. For standard label tapes, the data
set name has the following format, where jesn is the JES3
subsystem name.
jesn.DJ.Dyyyyddd.Thhmmss
For unlabeled tapes, the data set name is not unique and has the
following format, where jesn is the JES3 subsystem name.
jesn.DJOUT
To dump jobs to tape, issue the *START,DJ command and specify which
jobs you want dumped. In the example that follows, jobs in priority
4 will be dumped to tape:
*S,DJ,P=4
As a result of the *START command, dump job dumps the requested
jobs to tape:
*IEC501A M 0560,TAPVOL,SL,,IEESYSAS,DJ000034

You can now issue additional *START,DJ commands to dump other jobs
to tape. When you are finished dumping jobs to tape, you can cancel
the DJ DSP. As a result, the dump job server address space will close
the tape data set and end.
