Initialization Best Practices › Creating the VSAM File

Creating the VSAM File

Beginning with R15, the VSAM file is required to initialize CA Top Secret. We also recommend that you place the VSAM file on the following volumes:

• On a volume that other systems do not use heavily
• On a volume that is not subject to extensive I/O
• On a volume separate from the primary security file

Business Value:

The VSAM file can contain digital certificate, Kerberos, and data classification information that previously was stored in the Static Data Table (SDT). Using the VSAM file improves scalability.

Additional Considerations:

The Virtual Storage Access Method allows the transfer of information between the CPU's main memory and a direct access storage device. Records organized in logical key field sequence, in physical creation sequence, or by relative-record number, can be accessed directly or sequentially.
