To repdef or not to repdef – this is the question…

But sure that sense Is apoplexed…                                                                   I am of late have been involved in a lot of tuning activity around replication server.  Lots of things to tune.  Lots of hidden moving parts.  Complex creature (although […]

Sybase HADR: A glimpse at HADR option ported with ASE 16 SP02…

Now that SAP ASE comes with it own brand-new Always-On option it is worth having a closer look at it. Below is a peep-view at Sybase HADR Option. HADR has three basic components:  ASE, RS and Fault Manager.  I skip the Fault Manager for the moment (although it reduces all of self-management to nil) and […]
