To ask the question another way... Is it unusual, or expected, for a version 12.0.1.3457 dbsrv12 running with -im c on RedHat ES5.7 to have 0% checkpoint urgency throughout a 16 minute period of heavy activity, with no checkpoints taken during that period? Yes, it's not a very good sample, especially since it hasn't passed the standard-20-minute-boundary, but... I'm used to the checkpoint urgency increasing over time. And with -im c checkpoint-only-in-memory-mode it's those checkpoints that give you the only recoverability you have. ...tickle edit |

With In-Memory CheckPoint Only (-im c), I started the server with -gc option (or without), but does not perform automatic checkpoint. Only when shutdown or "checkpoint" command. What is missing? I use sql anywhere 16.0.0.2178 |
