  • IBM i 7.3 Adds Authority Collection Feature

    IBM i 7.3 has added a feature called “Security Authority Collection” which tracks how applications and application users “use” an object.  Inquiries against that collection will provide advice on securing critical business data and applications from intrusion by identifying who needs to have access to data and in what context.  This is a major enhancement to security management that is unique to IBM i.

    Leveraging SSDs and IASPs with BRMS Migration

    One significant change in IBM i 7.2 is the modernization of storage tiering in the BRMS migration function. In prior releases, the migration function in BRMS works only for library migration between auxiliary storage pools (ASPs) based on the specified policies for frequency of use. However, in IBM i 7.2 with PTF SI57831 applied, the BRMS migration function is enhanced to support the migration to independent ASPs (IASPs), migration of *LNK lists for IFS files, and migration of database files to different SSD and HDD storage tiers within the same ASP.

    SQL CPU Utilization was introduced in the IBM i 7.2 release.

The systemwide value is only available on 7.2, while the thread-level support was PTF’d back to 7.1.
