Multi-CPU Environments

In a multiple-CPU environment, perform the following actions:

• Place the following CA Top Secret files on a shared DASD volume:
  • Security file
  • Audit/tracking file
  • Recovery file
• If sharing a security file between multiple CPUs, specify the control option SHRFILE(YES) on each CPU.
• Back up the security file from one CPU only. Omit the BACKUP DD statement or code the BACKUP(OFF) control option on all systems but one.
• If “secured” data sets reside on shared DASD volumes and CA Top Secret is being used through one CPU only (usually during transition), system 913 abends might occur. Use program TSSPROT to remove the protection bits from the affected data sets. Set TSS control option ADSP as ADSP(NO) to prevent future data sets from being marked as protected.

Important! Due to VSAM file requirements, CA Top Secret r15 for z/OS can no longer share secfiles with CA Top Secret for z/VM or CA Top Secret for VSE.
