Business Continuity Manager, Tiered Storage Manager for Mainframe, and MAR use the same environment variables and system symbols. Therefore, if Tiered Storage Manager for Mainframe or MAR is running on the system, we recommend that you do not change the environment setting values (environment variables or the values set for system symbols) that are currently valid in the system. In particular, if you change the prefix for the license information dataset, you need to re-register the license for Tiered Storage Manager for Mainframe because the license information dataset is shared by Business Continuity Manager and Tiered Storage Manager for Mainframe. Keep this fully in mind when you need to change an environment setting value.
The following describes how to check the environment setting values that are currently valid in the system.
- If Business Continuity Manager has been installed (upgrade):
Check the environment setting values you obtained during the check before upgrading. For details, see Checking the setting values of the environment.
- If Business Continuity Manager has not been installed (new installation):
Use the KTDSPENV command of Tiered Storage Manager for Mainframe or the RSDSPENV command of MAR to check the values. For details on the KTDSPENV command, see the Tiered Storage Manager for Mainframe User Guide. For details on the RSDSPENV command, see the Mainframe Analytics Recorder User Guide.
