CA Dynam for VSE User Guide

IBM Hardware Based Tape Encryption Support
• The TLBL contains a valid file ID.
• The file ID found does not exist in the Catalog.
If all four of these conditions are met, CA Dynam/T generates a Catalog data
set base record for the data set name in the TLBL. The default values are
those specified in the DYNAM/T option record. You can use the DYNCAT ALTER
command to change these values for the new data set.
Removing Catalog Entries Automatically
Data sets which have been added to the Catalog by way of the automatic
catalog feature can be automatically removed from the Catalog. If you
specified AUTCATD(YES) in the DYNAM/T option record, CA Dynam/T
automatically deletes any data set that was automatically added when the last
active version in the data set is scratched.
This option provides a powerful tool for testing and controlling temporary data
sets on tape without requiring Catalog maintenance. You can create a test
version under a unique data set name with specific retention by simply coding
options on the output TLBL. When the specified retention has passed,
CA Dynam/T returns the tape to SCRATCH status, automatically removing the
test data set name from the Catalog.
Example:
Create the data set JOES.TEST and retain it for thirty days.
// TLBL MYFILE,'JOES.TEST,C',30
At the end of the thirty days, CA Dynam/T deletes the data set without any
manual Catalog intervention.
Sending File-Dependent System Messages
There is often a need to communicate with your Operations staff concerning
specific processing for a certain file at a certain time. Supplementary message
support provides a flexible means of defining your own messages and sending
them to the system console or printer at one or more of four points in file
processing.
You can define these messages in the Catalog by using the DYNCAT DEFINE or
ALTER commands. They will be issued automatically by the system at the
indicated point. For more information, see the chapter "Maintaining the
Catalog—DYNCAT Program."
