Configuring a Multilevel Secure System › Software Configuration

Software Configuration

Many components make up a z/OS system. Because some components depend on macros from other components, the installation sequence is important. The following list details one sequence that we recommend for CA Top Secret MLS system software installation, although other installation sequences work equally well:

• z/OS V1R5
• JES2
• JES3
• DFSMS
• TSO/E
• VTAM
• PSF
• ISPF
• TCP/IP
• z/OS UNIX System Services (UNIX)
• CA Top Secret
• CA Examine r3.5

Restrictions

If your site shares DASD, the following restrictions apply:

• All z/OS systems must be operating at z/OS V1R5 or higher
• z/OS MLS systems should not share DASD with systems that are not MLS.
• All z/OS MLS systems must share the same CA Top Secret databases
• All z/OS MLS systems in the global resource serialization complex must be the same set of z/OS systems that are sharing the CA Top Secret databases.
• The JES2 complex must be the same set of z/OS systems that are sharing the CA Top Secret databases or subset of these systems.
