CHKPT/RSTRT Program—TDYNRST
TDYNRST provides support for CA Dynam/T-controlled tape files in conjunction
with the VSE CHKPT/RSTRT facility. You do not have to make special
provisions for CA Dynam/T support when a program that has CHKPT/RSTRT
capability is initially executed.
If the program terminates normally, all files are cataloged as usual. However,
if it terminates early for any reason, and a restart is to be performed,
TDYNRST must be executed immediately before the RSTRT statement. The
operator is prompted to enter parameters that define the CA
Dynam/T-controlled files involved in the restart. When these have been
defined, TDYNRST does the following:
• Verifies that the volumes specified by the operator are the correct
volumes.
• Updates the label records and the Catalog entries to allow processing to
continue under CA Dynam/T control.
Use of this facility is subject to the following conditions:
• Submit all necessary TLBLs and ASSGNs before executing TDYNRST.
• Mount the input and output tapes on the correct drives, and assign the
logical unit through job control. TDYNRST does not perform AVR and does
not verify that the assigned physical tape has the correct volume serial
number.
• Establish the desired mode specification for output tapes on the ASSGN
statement. However, all other CA Dynam/T options are recognized from
the TLBL.
• Do not perform the DYNCAT SCRATCH function between the original
execution of the problem program and the restart.
