VCA BCSREQUIRED Statement
Valid operands are YES and NO. The default is NO. The BCSREQUIRED option affects the manner in which observations for the VCA_VS file (VSAM data sets) are constructed. Specify YES to require the BCS records for VSAM data sets or NO to allow observations for VSAM data sets to be written to the
MICS
database with BCS data missing.rm
BCSREQUIRED operand
Valid operands are YES and NO. The default is NO. The BCSREQUIRED option affects the manner in which observations for the VCA_VS file (VSAM data sets) are constructed. Specify YES to require the BCS records for VSAM data sets or NO to allow observations for VSAM data sets to be written to the
MICS
database with BCS data missing.Often, when excluding volumes during the Space Collector (VCC) run, a Base Catalog Structure (BCS) (user catalog) is not available for processing. When this happens, VCC only collects VVDS records describing the VSAM data sets.
The BCSREQUIRED parameter lets you specify that VSAM data set allocation information is or is not to be saved in the VCA_VS file when matching BCS records are collected.
The VCC Processing Flags (DAAPFLAG) is set to indicate the presence or absence of the BCS record as follows:
'11......'B - BCS and VVDS elements are present '01......'B - BCS elements are not present
VCA processes the BCS to obtain the following data elements. When the BCS records are not present, some data elements are not valid in the VCA_VS file. See VCA_VS - VSAM Data Set Allocation File for a list of elements affected by this.
