Oracle Database Diagnostic and Tuning Packs – exactly what are you not licensed for ?

It’s that time of year. The expense of Christmas is becoming apparent and January payday has seemed to be forever in arriving.
“…and I need a crown !”, said Deb.
This caused me to pause for a moment. Was my better half getting delusions of granduer ?
Further, delicate enquiries revealed that it was merely a dental crown to which she was referring.
Not that it seems to make much difference financially. You could probably buy a fairly substantial piece of regal headgear for what the dentist was asking.

On the plus side, Queen Deb’s costume for the next instalment of the Licensing Epic doesn’t require such accoutriments…although a big pair of headphones and lots of hairspray may be in order. Yes, I’m still on my Star Wars themed odyssey through Oracle Database Licensing.

In the previous posts, I’ve already covered :

Now, it’s time to get to grips with the licensing minefield that are the Diagnostic and Tuning Packs.
Queue the orchestra….

Episode 2 – Attack of the Diagnostic and Tuning Packs

Confusion is rife in the Data Centre. The Geeki have found that the incredibly useful AWR and ASH utilities are in fact secret members of The Diagnostic Pack.
Fearing the presence of the Dark Side, they must now re-enter the realms of the mysterious Oracle Database License to

  • Determine which features are part of these packs
  • Work out exactly what constitutes usage of these packs
  • find out which database objects that are part of these packs

With this information, at least they will know which objects they must avoid if they are not to have to pay substanital additonal licenses…

Disclaimer

This code has been written and tested on Oracle Database 11gR2 Express Edition.
The licensing information I’ve referenced is for Oracle Database 11gR2.
I’m fairly sure it all works as expected. However, as you undoubtedly know, you shouldn’t take my word for it.
Before you go playing around with this on any production environment, please make sure it does what I think it does.
Of course, if you do find any issues, I’d be great if you could put a comment on here so that I can correct any issues…and also to give a pointer to anyone else looking at this post.
Yes, I know the standard disclaimer about “similarity to events or persons living or dead” always goes at the end of the film, but I thought it best to put it at the start.
Incidentally, have you ever wondered exactly what real-life events Star Wars could have a similarity to ?

Decyphering the Ancient Holocron – Diagnostic and Tuning Pack Licensing

Whatever Database Edition you choose to install, the Diagnostic and Tuning Pack objects will end up sitting in your database.

Why look at these together, rather than separately ?
Well, one reason is that, if you want to use any Tuning Pack features, you must also purchas the Diagnostic Pack.

The ancient archives contain no clue as to why this would be, but it is thought that these tools were originally intended to be universally available. However, at some point, someone decided that they should be available only as additional cost options to the Enterprise Edition.
The assumption that the license documentation was written after the code would probably help in understanding what follows.

Let’s start by taking a look at the features included in each of these packs. This is worth doing as the feature usage auditing does not specify explicitly which database features are part of which pack ( or even if a feature is an additional cost option). As for most of this post, this information can be found in the Database Licensing Documentation.

Diagnostic Pack Features

So, from the licensing documentation, we can see that the Diagnostic Pack includes :

  • Automatic Workload Repository (AWR)
  • Automatic Database Diagnostic Monitor (ADDM)
  • Active Session History (ASH)
  • Performance Monitoring (database and host)

There’s other stuff in there, but the point is that some of the descriptions are a bit vague to say the least.
For example, “Performance Monitoring” – would that include BSTAT/ESTAT and tkprof ?
Well, no, it doesn’t. However, further clarity is needed here. We’ll come onto that in a moment.
First though, let’s take a look at…

Tuning Pack Features

The list for the Tuning Pack is a bit shorter but some ambiguity still remains :

  • SQL Access Advisor
  • SQL Tuning Advisor
  • Automatic SQL Tuning
  • SQL Tuning Sets
  • SQL Monitoring
  • Reorganize objects

Reorganize objects is another one of those ever-so-slightly fuzzy definitions.

Enabling and Disabling the Packs

Instructions are included for disabling access for both packs from Enterprise Manager.
There is also mention of the
CONTROL_MANAGEMENT_PACK_ACCESS init.ora parameter.
However, what neither of these settings will do is to disable access to the command-line APIs.
And here’s the rub. The documentation clearly states that any and all methods of accessing Oracle Diagnostics/Tuning Pack functionality, even through command-line APIs, or direct access to the underlying data, requires a license.

What we need then, is a comprehensive list of these APIs to help us avoid accidentally using the packs and incurring the resultant licensing costs.

Command Line APIs

Using the information in the licensing documentation, we’re going to build a table listing all of the command-line APIs for each pack. At least then, we’ll have a reference for database objects that we shouldn’t be using without licensing these packs.

The table

The table we’ll create to hold this information will consist of the following columns :

  • object_name
  • object_type
  • pack_name – the pack to which the object belongs or BOTH if it belongs to both of them
  • full_member – Y if it’s completely a member of the pack or N if it is only under certain circumstances
  • notes – details of the circumstances in which the object is considered a member of the pack
CREATE TABLE pack_members( 
    object_name VARCHAR2(30), 
    object_type VARCHAR2(20), 
    pack_name VARCHAR2(10), 
    full_member VARCHAR2(1), 
    notes VARCHAR2(4000)) 
/

Populating the table

First, the simple bit. This script populates the table with details of all the objects explicitly listed in the license documentation :

--
-- Script to populate the pack_members table with
-- Diagnostic and Tuning Pack API Objects that are individually specified by
-- the license.
--

--
--  DBMS_WORKLOAD_REPOSITORY
--
INSERT INTO pack_members(
    object_name, object_type, pack_name, 
    full_member, notes)
VALUES(
    'DBMS_WORKLOAD_REPOSITORY', 'PACKAGE', 'DIAGNOSTIC',
    'Y', NULL)
/

--
-- DBMS_ADDM
--
INSERT INTO pack_members(
    object_name, object_type, pack_name, 
    full_member, notes)
VALUES(
    'DBMS_ADDM', 'PACKAGE', 'DIAGNOSTIC',
    'Y', NULL)
/

--
-- DBMS_ADVISOR - NOTE - this is a member of BOTH packs
--
INSERT INTO pack_members(
    object_name, object_type, pack_name, 
    full_member, notes)
VALUES(
    'DBMS_ADVISOR', 'PACKAGE', 'BOTH',
    'N', 
    'DIAGNOSTIC PACK - Only if advisor_name => ADDM OR task_name LIKE ADDM%'
    ||' TUNING PACK - where advisor_name => SQL Tuning Advisor OR SQL Access Advisor')
/

--
-- DBMS_WORKLOAD_REPLAY
--
INSERT INTO pack_members(
    object_name, object_type, pack_name, 
    full_member, notes)
VALUES(
    'DBMS_WORKLOAD_REPLAY', 'PACKAGE', 'DIAGNOSTIC',
    'N', 'COMPARE_PERIOD_REPORT function only')
/

--
-- V$ACTIVE_SESSION_HISTORY
-- NOTE - this is a synonym for V_$ACTIVE_SESSION_HISTORY
--
INSERT INTO pack_members(
    object_name, object_type, pack_name, 
    full_member, notes)
VALUES(
    'V$ACTIVE_SESSION_HISTORY', 'SYNONYM', 'DIAGNOSTIC',
    'Y', 'Synonym for V_$ACTIVE_SESSION_HISTORY')
/

INSERT INTO pack_members(
    object_name, object_type, pack_name, 
    full_member, notes)
VALUES(
    'V_$ACTIVE_SESSION_HISTORY', 'VIEW', 'DIAGNOSTIC',
    'Y', 'Synonym for this view is V_$ACTIVE_SESSION_HISTORY')
/

--
-- DBA_STREAMS_TP_PATH_BOTTLENECK
--
INSERT INTO pack_members(
    object_name, object_type, pack_name, 
    full_member, notes)
VALUES(
    'DBA_STREAMS_TP_PATH_BOTTLENECK', 'VIEW', 'DIAGNOSTIC',
    'Y', NULL)
/

--
--  DBA_STREAMS_TP_COMPONENT_STAT
--
INSERT INTO pack_members(
    object_name, object_type, pack_name, 
    full_member, notes)
VALUES(
    'DBA_STREAMS_TP_COMPONENT_STAT', 'VIEW', 'DIAGNOSTIC',
    'N', 'Only rows where STATISTIC_UNIT = PERCENT')
/

--
-- DBMS_SQLTUNE
--
INSERT INTO pack_members(
    object_name, object_type, pack_name, 
    full_member, notes)
VALUES(
    'DBMS_SQLTUNE', 'PACKAGE', 'TUNING',
    'Y', NULL)
/

--
-- V$SQL_MONITOR - NOTE - this is a public synonym for V_$SQL_MONITOR !!!
-- Therefore, we'll specify the underlying view here as well
--
INSERT INTO pack_members(
    object_name, object_type, pack_name, 
    full_member, notes)
VALUES(
    'V$SQL_MONITOR', 'SYNONYM', 'TUNING',
    'Y', 'Synonym for V_$SQL_MONITOR')
/

INSERT INTO pack_members(
    object_name, object_type, pack_name, 
    full_member, notes)
VALUES(
    'V_$SQL_MONITOR', 'VIEW', 'TUNING',
    'Y', 'Synonym for this view is V$SQL_MONITOR')
/

--
-- V$SQL_PLAN_MONITOR - public synonym for V_SQL_PLAN_MONITOR.
-- Again, specify the underlying view here as well
--

INSERT INTO pack_members(
    object_name, object_type, pack_name, 
    full_member, notes)
VALUES(
    'V_$SQL_PLAN_MONITOR', 'VIEW', 'TUNING',
    'Y', 'Synonym for this view is V$SQL_PLAN_MONITOR')
/

INSERT INTO pack_members(
    object_name, object_type, pack_name, 
    full_member, notes)
VALUES(
    'V$SQL_PLAN_MONITOR', 'SYNONYM', 'TUNING',
    'Y', 'Synonym for V_$SQL_PLAN_MONITOR')
/

COMMIT;

Now things get slightly more involved. We’ve got to decipher the rules in the documentation to determine exactly which other objects are also part of the respective APIs…

--
-- Find all of the Diagnostic Pack views that are not specified by
-- name in the License and insert them into the PACK_MEMBERS table
--
INSERT INTO pack_members( 
    object_name, object_type, pack_name,
    full_member, notes)
    SELECT object_name, object_type, 'DIAGNOSTIC',
        'Y', NULL
    FROM sys.dba_objects
    WHERE owner = 'SYS'
    AND object_type = 'VIEW'
    AND (
        object_name LIKE 'DBA_ADDM_%'
    OR ( 
        object_name LIKE 'DBA_HIST_%'
        AND object_name NOT IN (
            'DBA_HIST_SNAPSHOT', 'DBA_HIST_DATABASE_INSTANCE', 
            'DBA_HIST_SNAP_ERROR', 'DBA_HIST_SEG_STAT', 
            'DBA_HIST_SEG_STAT_OBJ', 'DBA_HIST_UNDOSTAT')
        )
    )
    UNION    
    SELECT object_name, object_type, 'DIAGNOSTIC',
        'N', 
        'Only where ADVISOR_NAME = ADDM or TASK_NAME LIKE ADDM% '
        ||'or TASK_ID relates back to TASK_NAME that is like ADDM%'
    FROM sys.dba_objects
    WHERE owner = 'SYS'
    AND object_type = 'VIEW'
    AND object_name LIKE 'DBA_ADVISOR_%'
/
COMMIT;

After that, we should now have 165 records in the PACK_MEMBERS table. Of these, 159 are Diagnostic Pack, five are Tuning pack, and one – DBMS_ADVISOR – is part of both packs.

List of Diagnostic and Tuning Pack APIs

Now, finally, you can see all of the APIs for each pack in one place.
For the Diagnostic Pack :

SELECT object_name, object_type
FROM pack_members
WHERE pack_name IN ('DIAGNOSTIC', 'BOTH')
ORDER BY 2,1
/

The output is :


OBJECT_NAME                    OBJECT_TYPE

And now for the Tuning Pack :

SELECT object_name, object_type
FROM pack_members
WHERE pack_name IN ('TUNING', 'BOTH')
ORDER BY 2,1
/

The output is :


OBJECT_NAME                    OBJECT_TYPE                                      
------------------------------ ------------------------------

DBMS_SQLTUNE                   PACKAGE

V_$SQL_PLAN_MONITOR            VIEW                            

Ideally, there should be a way of disabling access to these objects and that’s a theme I’ll return to in a later post.
For now though, if you want to find the underlying tables for any of these views, you can do this fairly easily (remember, these
underlying tables will also trigger the license if accessed directly)…

SELECT dep.referenced_owner table_owner, dep.referenced_name table_name
FROM dba_dependencies dep, pack_members pm
WHERE dep.name = pm.object_name
AND dep.type = pm.object_type
AND dep.owner = 'SYS'
AND dep.referenced_type = 'TABLE'
AND pm.object_type = 'VIEW'
AND pm.object_name = 'DBA_ADVISOR_TASKS'
/

TABLE_OWNER                    TABLE_NAME                   
------------------------------ ------------------------------
SYS                            WRI$_ADV_TASKS                 
SYS                            WRI$_ADV_EXECUTIONS            

It’s not quite so good at getting a complete list of all the tables that fall into this category as some of the views actually reference tables that have nothing to do with these packs, such as COL$ and USER$.

In the next Episode…

Just when you thought it was all under control, the next post will attempt to address the question “Just what is the most expensive query I can run on Oracle ?”

No previews, but I can tell you that it’s related to the Diagnostic and Tuning Packs.
In the meantime, I’ve got to start doing some expectation management ahead of Valentines Day.
