The following sections provide an
overview of Tivoli Data Warehouse and the warehouse pack for Tivoli Decision
Support for OS/390 RACF Component.
The TEDW ID team maintains this overview.
Please contact us before changing it.
Tivoli Data Warehouse provides the
infrastructure for the following:
·
Extract, transform, and load (ETL)
processes through the IBM DB2 Data Warehouse Center tool
·
Schema generation of the central data
warehouse
·
Historical reports
As shown in Figure 1, Tivoli Data Warehouse consists of a centralized data
store where historical data from many management applications can be stored,
aggregated, and correlated.
Figure 1. Tivoli Data Warehouse basic architecture
The central data warehouse uses a
generic schema that is the same for all applications. As new components or new
applications are added, more data is added to the database; however, no new
database objects are added in the schema.
A data mart is a subset of a data
warehouse that contains data that is tailored and optimized for the specific
reporting needs of a department or team.
The central data warehouse ETL
reads the data from the operational data stores of the application that
collects it, verifies the data, makes the data conform to the schema, and
places the data into the central data warehouse.
The data mart ETL extracts a
subset of data from the central data warehouse, transforms it, and loads it
into one or more star schemas, which can be included in data marts to answer
specific business questions.
A program that provides these ETLs is
called a warehouse pack.
The ETLs are typically scheduled to run
periodically, usually during non-peak hours.
Tivoli Decision Support for OS/390 is
structured with several components relative to the different applications where
it collects data. Consequently also the Extract Transform and Load processes
will be defined as different “subject areas” according to each Tivoli Decision
Support component. For instance in the “DB2 Warehouse Center” one can find as subject
areas, if the corresponding warehouse enablement packs were installed, as
follows:Tivoli Decision Support for OS/390 is structured with several
components relative to the different applications where it collects data.
Consequently also the Extract Transform and Load processes will be defined as
different “subject areas” according to each Tivoli Decision Support component. For instance in
the “DB2 Warehouse Center” one can find as subject areas, if the corresponding
warehouse enablement packs were installed, as follows:Give an overview of your
warehouse pack. Include information that would be helpful for understanding the
overall flow of application-specific data in and out of the central data
warehouse and data marts. Data flow diagrams worked well for some products.
Provide customer-centric rationale on what
benefit customers obtain from installing the warehouse pack. Discuss report
capabilities generically and insert a cross reference to the reports section.
If the warehouse pack does not provide
reports, describe how other Tivoli applications provide value to your product
data. Here is an example statement for warehouse packs that are to be used by
Tivoli Service Level Advisor: The warehouse pack for Tivoli SAN Manager
extracts data from the Tivoli SAN Manager Enterprise Repository database. The
warehouse pack then loads that data into the central data warehouse. The
collection of data from Tivoli products into one central data warehouse lets
you see trends in operation, resource usage, and cross-product
interoperability. The historical data from Tivoli SAN Manager is provided to
use by Tivoli Service Level Advisor and Tivoli Storage Manager.
Tivoli Decision Support for OS/390 is
structured with several components relative to the different applications where
it collects data. Consequently the
extract transform and load processes are also defined as different Subject
Areas according to each Tivoli Decision Support component. For instance in
the “DB2 Warehouse Center” you can find the following Subject Areas, if the
corresponding warehouse packs were installed:
·
D01_TDS/390-MVS_v1.6.0_Subject_Area (ETLs for Tivoli Decision Support
for OS/390 System performance feature MVS component)
·
D07_TDS/390-OPC_v1.6.0_Subject_Area (ETLs for Tivoli Decision Support
for OS/390 System performance feature OPC component)
·
D09_TDS/390-RACF_v1.6.0_Subject_Area (ETLs for Tivoli Decision Support
for OS/390 System performance feature RACF component)
The relationship between Tivoli Decision
Support and Tivoli Data Warehouse through the ETL processes varies according to
the different tasks they perform. The graph below shows what has been just
stated:
Figure 2. Overview of the warehouse pack
for Tivoli Decision Support for OS/390
This figure refers only to the central data
warehouse loading, because this warehouse pack does not provide either data
marts or reports.
To understand how Tivoli Decision Support
for OS/390 interacts with Tivoli Data Warehouse, see that topic in Installing
and Configuring Tivoli Data Warehouse.

WRITERS: Optionally, provide a screen shot
of the final report. If you put several graphics in Word, eventually Word will
crash. So you can put some representative report screen shots instead of every
one.
DEVELOPERS: To send your report
requirements to the report vendor, be sure to include a graphic representation
of each report that you would like the report vendor to create. If Word starts
to crash because you have 10 or more graphics imported into the template, put
the graphics in a separate document so that they can be sent with the template
to the enabling team.
This section describes the installation
and configuration of the warehouse pack.
Every prerequisite application and version
number must be listed either below or in your product document that contains
the full list of software/hardware prerequisites. This list must include
version numbers for supported databases, fix packs for databases, version of
Tivoli Data Warehouse, fix packs/interim fixes for Tivoli Data Warehouse, and
fix packs for your product.
Before installing the warehouse pack for
Tivoli Decision Support for OS/390 RACF component, you must install the
following software:
·
IBM Tivoli Decision Support for OS/390
Version 1.6 System performance feature with the following component:
Ø
RACF Component
·
IBM DB2 Universal Database, Version
7.2
·
IBM DB2 Universal
Database for z/OS and OS/390, Version 7 (If your app works on 390, you need this. Otherwise
delete.)
·
Tivoli Data Warehouse, Version 1.2 and
its prerequisites
·
Crystal Enterprise and its
prerequisites
(If your application
requires another warehouse pack to make your application function correctly
with TDW, you need this. Otherwise delete.)
If your product
specifies in the twh_install_props.cfg file whether each central data warehouse
or data mart can be specifically on z/OS, distributed or both, document the
number of systems and locations for the data marts and central data warehouses.
This warehouse pack
supports central data warehouses on DB2 UDB for z/OS and OS/390.
Refer to the Tivoli Data Warehouse
Release Notes and Tivoli Decision Support for OS/390 Administration
Guide for specific information about hardware prerequisites, database and
operating system support, and product prerequisites. For late-breaking news
about prerequisites, refer to the following IBM Software Support Web site:
http://www.ibm.com/software/sysmgmt/products/support/
For performance and disk capacity
reasons, data from Tivoli Decision Support for OS/390 can only be stored in the
central data warehouse database on OS/390 system.
In addition, place Tivoli Decision Support
for OS/390 in the same DB2 subsystem as
central data warehouse.
To avoid resource contention, warehouse
packs on OS/390 must be run in sequence. See the following sections for
instructions on how to install and schedule multiple Tivoli Decision Support
for OS/390 warehouse packs.
Describe restrictions, limitations, known
bugs, etc. in this section. Use section heads to indicate each item, product
note, or limitation.
Refer to the “Estimating the size of your
Tivoli Data Warehouse deployment” in Installing
and Configuring Tivoli Data Warehouse manual.
Accurate database
sizings are important for capacity planning purposes. Customers need to know
the number of rows inserted into key tables to calculate throughput and determine
how long the ETLs will run. Customers also need the base size and daily growth
size to calculate the amount of disk space required for their databases.
Describe the
database-sizing considerations, which include:
·In
the central data warehouse, space for the historical data. See below for an
example showing how the user calculates that value.
·In
the data mart, space for summarized data.
·In
the control database on the control server, space for metadata defining data
marts and reports.
·In
your application's operational data sources, space for tables that are created
by the warehouse pack. (Not all applications do this.)
·In
<specify database>, space for staging tables. The staging tables usually
are approximately equivalent to 1 day’s worth of database space.
·Any
other space requirements you have.
·If
possible, provide formulas and worksheets.
In summary what is
really needed for each database (TWH_CDW, TWH_MART and TWH_MD) is:
·An
estimate of the number of rows of data in key tables based on size of the environment
(Comp, Comptyp, Msmtyp)
·A
formula to calculate the base database size.
·An
estimate of the number of rows of data inserted into key tables based on the
number of Measurements per day (i.e Msmt)
·A
formula for calculating the daily size growth of the database.
.
This is just a sample of how to
approach this. Create worksheets that work for your product's components.
<Here is an example for an imaginary
warehouse pack. Delete this after reviewing.>
There are no pre-installation procedures
for this warehouse pack.
List any steps the customer must do before
running the warehouse pack installation program. For example, this might
include tasks such as creating additional tables in an existing database or
establishing an ODBC connection.
If there are none, say: This warehouse
pack requires no pre-installation procedures.
To install this warehouse pack, perform
the following steps:
1.
Make sure that Tivoli Decision Support
for OS/390 is installed and the data source is available.
2.
Make sure that all prerequisite
product patches are applied.
3.
Make sure that Tivoli Data Warehouse
is installed. For instructions about installing Tivoli Data Warehouse, refer to
Installing and Configuring Tivoli Data
Warehouse.
4.
Record the following information that
will be used during the installation:
|

(for example TCDW1)
Customer fills
this in.
|
5.
Install the
warehouse pack as described in Installing and Configuring Tivoli Data
Warehouse, using the installation properties file (twh_install_props.cfg)
located in the tdw_weps\d09\ v1200 directory.
6.
If you want to run
multiple warehouse packs on OS/390 select “Do not schedule the data extraction,
transformation and loading”, when the ETL configuration window is
displayed. In this way you are able to
manually schedule ETLs in sequence as explained in the following Post-installation
procedures section.
7.
Perform the post-installation steps
described in Post-installation procedures.
The ODBC source is
the data source name you put in the twh_install_props.cfg file. If your
warehouse pack is capable of having multiple sources of data, then add a line
for each data source below. State that they have to specify the ODBC connection
information for each additional data source while installing the warehouse
pack.
Provide the location of the installation
media. You do not need to explain how to install Tivoli Data Warehouse.
Complete the following post-installation
procedures.
Before running any ETL process, if this
is the first Tivoli Decision Support for OS/390 warehouse pack that you are
installing and you have installed Tivoli Decision Support for OS/390 using a
schema (Tivoli Decision Support for OS/390 table prefix) name different from
DRL (which is the default name), you must customize the db2os390.translate
file, as described in Installing and Configuring Tivoli Data Warehouse. For instance, if your schema name is DRLxxx,
you must change the following:
__TDS390_SCHEMA DRL
into:
__TDS390_SCHEMA DRLxxx
If you are installing this warehouse pack
as the only OS/390 warehouse pack, you can schedule it using the ETL
configuration window during the installation steps. On the contrary, if you are
installing multiple OS/390 warehouse packs, you must ensure that their ETLs
must be run in sequence. During the installation process, you selected “Do not
schedule data extraction, transformation and loading”. Now you must create
shortcuts in the Data Warehouse Interface to link the ETL processes in
sequence. With shortcuts you specify only the first ETL process runs. All the
other processes run automatically because they are linked to that process. For
details see “Scheduling warehouse pack ETL processes” in Installing and
Configuring Tivoli Data Warehouse manual.
If there are none,
say: This warehouse pack requires no post-installation procedures.
If your warehouse pack doesn't have any
dependencies between processes, delete that part of the step.
This
warehouse pack has no migration from previous release.
To uninstall the warehouse pack on your computer select Start>
Programs> Tivoli Data Warehouse> Uninstall a Warehouse Pack. For
further information see Installing and Configuring
Tivoli Data Warehouse, “Uninstalling warehouse pack” chapter. Before
uninstalling the warehouse pack, you can delete the related data from
the central data warehouse by running a specific SQL script. A sample of it can
be found in the twh\apps\d09\v1200\misc directory, the name is
d09_data_delete.sql. The sample deletes both the static data and the instances
loaded in the central data warehouse by this warehouse pack. Before running
this script make sure you do not need those data anymore and make sure you are
connected to the central data warehouse Database on host.
To uninstall
the Warehouse pack using this script open a DB2 Command Window and enter the
following command from the twh\apps\d09\v1200\misc directory:
db2 –z
<your logfile name> -tvf d09_data_delete.sql
The sample provided
is deleting both the static data and all the instances loaded in the CDW by the
ETLs.If your warehouse pack requires the user to perform additional steps
beyond what is documented in the Installing and Configuring Tivoli Data
Warehouse guide, then list them in order. If your warehouse pack requires a
different uninstall order, reflect that here. If there are no additional steps,
delete the steps.
If your application
and warehouse pack do not use fully qualified host names and Centr_Cd, then you
need to provide examples and description of how the customer will create the
lookup table for multiple data centers.
After you install the
warehouse pack, you can configure Tivoli Data Warehouse to separate data for
multiple data centers. To set this up, you must create SQL scripts with the
following values:
|
Information
for scripts
|
Value or
location
|
|
Field in source
data
|
MVS System IS
|
|
Name of lookup
table
|
D09.Centr_lookup
table
|
|
Name of center
list
|
TWG.Centr
|
For the procedural
instructions and example of SQL
statements, see the information about warehouse pack installation in the Installing
and Configuring Tivoli Data Warehouse guide.
After the
configuration for multiple data centers, you must modify the tables when data
centers are added and removed.
If your application
and warehouse pack do not use fully qualified host names or the customer
account code/customer ID, then you need to provide examples and description of
how the customer will create the lookup table for multiple customer
environments.
After you install the
warehouse pack, you can configure Tivoli Data Warehouse to separate data for
the multiple customer environments. To set this up, you must create SQL scripts
with the following values:
|
Information
for scripts
|
Value or
location
|
|
Field in source
data
|
MVS System ID
|
|
Name of lookup
table
|
D09.Cust_lookup table
|
|
Name of
customer list
|
TWG.Cust
|
For the procedural
instructions and example of SQL
statements, see the information about warehouse pack installation in the Installing
and Configuring Tivoli Data Warehouse guide.
After your
configuration of the multiple customer environments, you must modify the tables
when customers are added and removed.
Describe any maintenance tasks required
for this warehouse pack.
This section describes maintenance tasks
for the warehouse pack.
Together with the procedures describing
maintenance tasks in Installing and
Configuring Tivoli Data Warehouse, it is recommended that you back up your
data on a regular basis. Ensure you have sufficient back up to restore as much
event data as you need to store in the central data warehouse.
For further
information refer to the section about backing up and restoring in Installing and Configuring Tivoli Data
Warehouse.
Describe any special
backup and restoration considerations. For example, if the warehouse pack
requires that additional tables be created in the operational data store, these
tables must be backed up.
To manage the high volume of measurement data, use the
Prune_Msmt_Control table where the deletion criteria are specified. The
Prune_Msmt_Log table keeps a history of all data deletion activity.
For further information refer to “Pruning data from the
central data warehouse” in Enabling an
Application.Describe any special data pruning considerations. For example,
if the warehouse pack requires that additional tables be created in the
operational data store, these tables may need to be pruned.
By default the data older than the deletion criteria
specified in the Prune_Msmt_Control table is deleted when the CDW_c05_Prune_and_Mark_Active process
runs. This process is within the CDW_Tivoli_Data_Warehouse_v1.2.0_Subject_Area.
By default, this process runs daily at 6:00 a.m..
Include this optional statement if your warehouse pack
uses measurement data. Otherwise, delete this section.

Note: PMsmtC_Age_In_Days column contains the "Prune Measurement Control
Age in Days”. This is the age at which measurements are deleted (day duration yyyymmdd).
For
successful Tivoli Data Warehouse maintenance do not change the Tivoli Data
Warehouse ETLs, but rather create new ETLs in another subdirectory of the apps
directory. At the same time define your process in the Data Warehouse
Center. Tivoli Data Warehouse provides
standard maintenance of its subdirectories and processes, if not modified.
Refer to Enabling an Application for details on how to create your ETLs.
If you have additional maintenance tasks,
describe them in additional sections. Please notify the TDW ID team so that
they can consider whether that new maintenance task is common enough to be
added to this template.
If you have any
additional troubleshooting information, describe it here. Before documenting a
problem/solution, check the Installing and Configuring Tivoli Data Warehouse
guide to see if the topic is already documented there.
For common problems
and solutions, see the Installing and Configuring Tivoli Data Warehouse
guide.
The warehouse pack has the following
process:
·
D09_c05_RACF _Process
5.1 D09_c05_RACF_Process
Repeat this section for each process.
Explain the function of the process, list
its process steps, and describe the function of each step. If steps need to be
linked together, explain how they connect. Installing and Configuring Tivoli
Data Warehouse has instructions for linking steps together. You need to
tell them if they need to do that and what links are needed.
State whether the process is run once or
repeatedly. Explain the circumstances in which it runs, for example, a process
might be run once immediately after installing the warehouse pack to configure
it. A repeated process might run nightly to extract data from an operational
data store or periodically to delete data from the warehouse. If the process is
specific to the central data warehouse ETL or the data mart ETL, explain that.
Explain how to recognize when the process
fails, and what to do if that happens. A common cause of errors is nonvalid
data in the source database. The ETL process creates exception tables. Explain the corrective action to take for
common errors.
This process is used to load component
and measurement tables from source data into the central data warehouse database.
The process has the following steps:
·
D09_c05_s010_processRACF
This step
populates the component table (Comp table),the component attribute table
(CompAttr table) and the component relationship table (CompReln table).
·
D09_c05_s020_processRACF
This step
populates the measurement table (Msmt table).
This section is in landscape mode on
purpose. The tables are too wide for portrait presentation.
This section provides the heart of the
application integration information-how the application's operational data maps
to the data being stored in the central data warehouse. Information developers
should work closely with developers to provide complete and meaningful
information. Detailed data descriptions are crucial to effective data sharing.
Information that is saved in the central
data warehouse will be visible to the customer in reports, in the Tivoli
Service Level Advisor (TSLA) GUI, and other tools. The customer should be able
to look at a component name (Comp_Nm) and have some clue what resource is being
measured.
While the content of the tables changes
from application to application, most applications will have data in all of the
tables shown in this section. All columns might not be used and therefore do
not contain any information.
Before reading this section, read about
the generic schema for the central
data warehouse, which is described in Enabling an Application for Tivoli
Data Warehouse. That document defines the content of each table and
explains the relationships between the tables in this document.
Describe how you came
about the data values you put in the tables in this section. The following is
an example from NetView. Modify it so that it applies to your product.
This section provides
an example of how information is stored in Tivoli Data Warehouse. The
data values shown in the following tables come from a generic installation.
Shaded central data warehouse columns
indicate values that source applications must translate and deliver
corresponding Java resource bundles. Internationalization of data is described
in Enabling an Application for Tivoli Data Warehouse.
Note to writers:
If you are documenting one of the IBM
Tivoli Monitoring PACs, ask your developers whether they had to edit the
resource bundle. If they did, that means that they didn't use translatable
words in the MsmtTyp_Nm field (and possibly others), but it wasn't noticed
until after testing was too far along to change the value. They
"fixed" this for translation by hand editing the resource bundle
files that are sent to translation, without changing the scripts that created
the untranslatable strings in the database.
That means that the database contains one
value (usually a camel case abbreviation like PctCPUBusy), but the report
interface will show a different, human-readable value (for example, Percent CPU
Busy). If this happened, you need to
add info in the section describing that column to explain it and to help them
map the database value to the translated string. Some of the strings will be
translatable if you ignore the underscores (Percent_CPU_Busy). This is
important for people writing reports to know the values they will see in the
database. You have to do this for each
item they hand-edited.
A table showing the corresponding values
might be a good idea. For example, something like this:
The values for MsmtTyp_Nm are stored in
the central data warehouse as a short string, but are displayed in reports as
descriptive phrases. The following
table shows how the values of MsmtTyp_Nm in the database correspond to the
values displayed in reports.

PctCPUWait
|
Percent_CPU_Wait

Shaded columns in the following tables
are translated. These columns are also marked with an asterisk (*) after the
column name.
Some of the commonly used static data is
listed below. Remove any that you are not using. Also, depending on your
application you will add additional static data types.

Note1: The
Comp_Corr_Val column is used to correlate the component instance to its
parents. In the above Comp table sample this column was left empty
for better readability. However in a real case, for this warehouse pack, it is
built using the following structure:
CompType_Cd Component instance Comp_Corr_Val
MVS_SYSTEM mvs_system_id ----
MVS_SYSAPPL sysappl_name "MVS - mvs_system_id"
Note2: The Component Name (Comp_Nm column) , for components of
type MVS_SYSTEM, contains the MVS System Identifier (SID) as specified in the SMFPRM00 member in the SYS1.PARMLIB.
The SID is 1 to 4 characters long.
Note that an alternative
MVS identifier is the SYSNAME which is 1-8 characters long and could also be
used in the future.

Data extraction into Tivoli Data Warehouse is done in an
incremental way.
New data from the source database
is loaded into the data warehouse by checking that the existing measurements
for a component are older than the new available ones.
The following columns d09.stage_cntl table store this information:
·
cntl_comp_id (INTEGER)
·
cntl_dttm (TIMESTAMP)
When loading measurements, this control table checks
each comp_id, and accepts only those with a newer timestamp.
After successful loading of the
measurement data, this control table is updated with the last timestamp present
in the twg.msmt table for each comp_id.
Applications should describe their design
for incremental extracts in this section. If not part of the warehouse pack,
state “This warehouse pack does not have incremental extraction.”
For example, you could state something
like: “This warehouse pack uses incremental extraction to extract data from the
central data warehouse and store it into the data mart tables. The data in the
TWG.Extract_Control table controls this process.” Then you can provide what the
entries would be in the TWG.Extract_Control table. Here is an example from
