All right. Let’s look at a sampling. We mentioned again, lots of different metrics in the accounting data, and let’s look at a sampling of some of the other metrics available.

Here we have the rate of commits by plan.

Here we have the number of rollbacks by plan.

We can also look at the volume of log data. You know, some plans are continuously executing, others are used by batch jobs that have discreet start and end times.

We can also look at the volume of SQL statements by type for a plan. So let’s go down to that plan that had all the sync read I/Os. And so here’s the volume of SQL statements, opens, closes, fetches, and so on that generated by that plan.

Now earlier we viewed counts of suspension events for DDF work by auth ID. We can learn from exploring those suspension counts across all connection types.

For example, here’s a view of the way of the suspensions by connection type with DDF excluded. So for example, here, we see that the IMS message processing region work in this environment experiences far more global lock contention for parent L locks than the other connection types. And then from here, we can explore and see which applications, which plans are experiencing a lot of that global lock contention. If we instead want to view the suspension events by plan, here again we see this DQPS plan that we’ve seen a few times earlier, already.

And again, lots of sync I/O waits. We saw that earlier, but it also has many waits for other read I/O, which as we talked about earlier was associated with prefetch I/Os.
