Oracle Management Packs

There has been quite a bit of confusion about the licensing of Oracle Management Packs and about their functionality. Here are a couple of links to the Oracle Docs which describe what’s not allowed without licensing these packs.

10gR2 Management Pack Licensing

11gR1 Management Pack Licensing

A couple of things to be aware of.

1. They are only available with Enterprise Edition
2. The Tuning Pack depends on the Diagnostic Pack

11gR1 includes a new parameter (CONTROL_MANAGEMENT_PACK_ACCESS) which controls access to features based on the Diagnostic and Tuning Packs at the database level. The valid values for this parameter are NONE, DIAGNOSTIC, and DIAGNOSTIC+TUNING. Setting this parameter to NONE disables several features at the database level including AWR (which is the only feature I’ll discuss in this post). By the way, the default is TUNING+DIAGNOSTICS, so AWR is still enabled by default. Also, note that snapshots are still created, even if the parameter is set to NONE, but they don’t contain any data. So they are not just limiting access to the reporting capability, but also disabling the collection of data. Here’s a quick example on a 11.1.0.7 database:

I’m pretty sure about the Snap_Mode (i.e. whether it’s automatic or manual) because of the code snippet we saw in the usage monitoring package (DBMS_FEATURE_REGISTER_ALLFEAT). The Data_Collection part is just a guess based on my observation (and very little observation actually, so there may well be other possibilities), but it appears that the 3rd bit (4) is on (1xx) when data has not been gathered (i.e. when CONTROL_MANAGEMENT_PACK_ACCESS=NONE). I have no idea what the second bit does by the way. So here’s a little script to look at the snapshots using what we’ve learned thus far (it shows the number of SQL statements on which data has been collected as a verification of whether data has been collected for this snapshot or not):

So what’s this good for. Well not that much probably, but at least we’ll be able to easily see what we can and can’t access with or without the DIAGNOSTICS and TUNING packs. And it’s nice to know that, if were’ not licensed to use AWR, we can turn off the collection of the data easily. (No sense spending CPU cycles collecting data we’re not licensed to look at)
