Historical data in a multisystem, multiproduct environment
Each PAS on each system requires a unique historical database. Use the system's SMF ID as the second qualifier and the PAS ID as the third qualifier when allocating the VSAM data sets to indicate the system and PAS to which each historical database belongs; for example, hilevel. smfid. pasid.HISTDS01. This distinguishes one system's historical data sets from another's and ensures the integrity of each system's data.
MainView products that share the same PAS on the same system also share the same historical data sets.
