The CTTSBD utility searches the Media database for data sets and volumes that satisfy selection criteria specified in INCLUDE / EXCLUDE statements.
Selected volumes are sorted according to the volser of the first volume in each input volume chain. Each data set on each selected volume chain is then copied to a new volume or volume chain. Various parameters are used to control the actions taken by the CTTSBD utility, such as
whether to copy expired data sets
which data sets can reside together on the same output volume chain
how many data sets or volumes can be in a volume chain
When a data set is successfully copied, the CTTSBD utility updates the relevant Media database records and catalog information according to user specifications. Using the CTTSBD utility parameters, the user can indicate
cataloging of the output data set (OUTCAT parameter)
retention of output and/or input data sets (OUTRET and INRET parameters)
Vault pattern of output and/or input volumes (INVAULT and OUTVAULT parameters)
copying of certain historical information about the input data set to the output data set record (COPYATTR parameter)
The CTTSBD utility terminates when one of the following occurs:
All selected volumes have been processed.
An operator command is issued (see "Modify Command").
A specified number of input volumes have been processed (NUMVOL parameter).
A specified maximum amount of time has passed (TIMELIM parameter).
Processing of a specified maximum allowed number of input volume chains is stopped due to runtime errors (MAXERR parameter).
