The console dialog would be:

CADT570D ENTER 'Y' FOR TDYNRST PARAMETERS
(EOB)
CADT551D ENTER TDYNRST PARAMETERS
TAPEIN,817,2,I
CADT561I FILE TAPEIN LABEL HAS BEEN UPDATED
CADT551D ENTER TDYNRST PARAMETERS
TAPEOUT,243,3,0
CADT561I FILE TAPEOUT LABEL HAS BEEN UPDATED

CADT563I TDYNRST END

Note: TDYNRST reads control statements from SYSIPT rather than SYSLOG
when executed with an UPSI 1.
Synchronizing Volumes (using XSYSTEM)—TDYNSYNC
The TDYNSYNC utility program provides for synchronization between two
catalogs that share tape volume status information by way of the
Cross-system (XSYSTEM) interface. CA Dynam/T and CA 1 MVS are two
systems that utilize this interface. XSYSTEM can also be shared among
multiple CA Dynam/T catalogs running on separate physical or virtual CPUs.
Before establishing a cross-system interface, review all relevant
documentation for all sharing systems. For more information about the
DTNODE and DTPATH option records, see the Programming Guide.
Described later in this section are the control statements TDYNSYNC uses to
perform a variety of functions.
Creating Multi:ACCESS Queue Files for an External Tape System
In order to use the XSYSTEM interface, you must define Multi:ACCESS (MACC)
queue files formatted as DOS- or OS-formatted files. The MACC queue files
serve as data transmission media, or message paths. They are defined in the
PATHID parameter of the DTPATH option record. A separate MACC queue file
must be created and initialized once for each pathid specified in the DTPATH
option record.
The MACC queue files must reside on DASD devices accessible by the FROM
and TO systems using the corresponding paths defined in the DTPATH option
record.
