Db2 Cloning Tool: Enhanced App Cloning Index Processing (PI99726)
If you perform Application (Tablespace) Cloning with the Cloning Tool, chances are that you will experience a free performance boost after applying APAR PI99726 (PTF UI57180).

Db2 Cloning Tool: What is Skeleton Cloning?
Unless you’ve seen a presentation on the Cloning Tool, you may not be aware of support for something called Skeleton Cloning. The only references to “skeleton” in the user guide are in the context of ISPF, and there’s no mention of it in the panels or profiles. Skeleton Cloning is a subset of Subsystem Cloning, […]
Db2 Cloning Tool Version Mismatch Processing
Db2 Online/Pending alters are a great thing for Db2 schema evolution. This does, however, create an interesting challenge for application cloning operations.

Five things from yesteryear that have still “got it”
Nostalgia, or “a sentimental longing or wistful affection for a period in the past,” is a common occurrence in adulthood and has never been as visible as it is today. Think about hipster-culture—bringing back old game consoles like the Nintendo 64, and shunning Spotify in favor of vinyl (it just sounds better). While initially, users […]
