Oracle Management Packs
http://kerryosborne.oracle-guy.com/2008/10/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.
- They are only available with Enterprise Edition
- 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:
SQL> @test_cmpa
SQL> --
SQL> -- Test setting control_management_pack_access=NONE
SQL> --
SQL> select name,value from v$parameter where name like '%pack%'; NAME VALUE
-------------------------------- ------------------------------
control_management_pack_access DIAGNOSTIC+TUNING SQL> select snap_id, begin_interval_time, snap_level, snap_flag from dba_hist_snapshot where snap_id = (select max(snap_id) from dba_hist_snapshot); SNAP_ID BEGIN_INTERVAL_TIME SNAP_LEVEL SNAP_FLAG
---------- ------------------------- ---------- ----------
3826 27-OCT-08 08.12.32.405 PM 1 1 SQL> select count(*) from dba_hist_sysstat where snap_id = (select max(snap_id) from dba_hist_snapshot); COUNT(*)
----------
500 SQL> alter system set control_management_pack_access=NONE; System altered. SQL> select name,value from v$parameter where name like '%pack%'; NAME VALUE
-------------------------------- ------------------------------
control_management_pack_access NONE SQL> @awr_snap
SQL> exec dbms_workload_repository.create_snapshot(); PL/SQL procedure successfully completed. SQL> select snap_id, begin_interval_time, snap_level, snap_flag from dba_hist_snapshot where snap_id = (select max(snap_id) from dba_hist_snapshot); SNAP_ID BEGIN_INTERVAL_TIME SNAP_LEVEL SNAP_FLAG
---------- ------------------------- ---------- ----------
3827 27-OCT-08 08.13.10.553 PM 1 5 SQL> select count(*) from dba_hist_sysstat where snap_id = (select max(snap_id) from dba_hist_snapshot); COUNT(*)
----------
0
So it seems clear that the setting affects not only reporting but also collecting since no records were created in the DBA_HIST_SYSSTATS view. You may have also noticed the SNAPSHOT_FLAG column which is new in 11g. This column is used for a couple of purposes. First, it indicates whether the snapshot was generated manually using the dbms_workload_repository.create_snapshot procedure or automatically by the standard scheduled AWR snapshot process. I’m not sure why that is important, but hey, what do I know. I guess someone at Oracle decided that checking on manually created snapshots is a way to track AWR usage. Here’s an excerpt from the DBMS_FEATURE_REGISTER_ALLFEAT package which is used to monitor usage of “special” features.
/**************************************
* Automatic Workload Repository (AWR)
**************************************/ declare
DBFUS_AWR_STR CONSTANT VARCHAR2(1000) :=
'select count(*), NULL, NULL ' ||
'from wrm$_snapshot ' ||
'where dbid = (select dbid from v$database) ' ||
'and status = 0 ' ||
'and bitand(snap_flag, 1) = 1 ' ||
'and end_interval_time > ' || DBFUS_LAST_SAMPLE_DATE_STR; begin
dbms_feature_usage.register_db_feature
('Automatic Workload Repository',
dbms_feature_usage.DBU_INST_ALWAYS_INSTALLED,
NULL,
dbms_feature_usage.DBU_DETECT_BY_SQL,
DBFUS_AWR_STR,
'A manual Automatic Workload Repository (AWR) snapshot was taken ' ||
'in the last sample period.');
end;
By the way, there are a couple of views that will allow you to see how your database is spying on you (DBA_FEATURE_USAGE_STATISTICS and DBA_HIGH_WATER_MARK_STATISTICS). Here’s a couple of scripts to look at them, feature_usage.sql and feature_hwm_stats.sql. Note that these views exist in 10gR2 as well, so these scripts will work in a 10g environment as well.
SQL> @feature_usage
SQL> set lines 132
SQL> set pages 999
SQL> break on version skip 1
SQL> select version, name, detected_usages, currently_used, first_usage_date, last_usage_date
2 from DBA_FEATURE_USAGE_STATISTICS
3 where detected_usages > 0
4 order by 1, 2

But I digress, remember the SNAP_FLAG field that I said was used for a couple of purposes. Well the second thing it’s used for is as an indicator of whether there is any data associated with a snapshot (i.e. if the CONTROL_MANAGEMENT_PACK_ACCESS parameter was set to NONE when the snapshot was generated). So after a little playing around here’s a table of possible values:
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):
SQL> @awr_snaps2
SQL> col snap_mode for a10
SQL> col awr_mode for a10
SQL> select a.snap_id, snap_flag,
2 decode(bitand(snap_flag,1),1,'Manual','Automatic') Snap_Mode,
3 decode(bitand(snap_flag,4),4,'Off','On') Data_collection,
4 count(sql_id)
5 from dba_hist_snapshot a, dba_hist_sqlstat b
6 where a.snap_id = b.snap_id(+)
7 and begin_interval_time > sysdate-1
8 group by a.snap_id, snap_flag
9 order by 1
10 / SNAP_ID SNAP_FLAG SNAP_MODE DATA_COLLECTION COUNT(SQL_ID)

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)
