OLAP DML - aw access via AWM

Hi All,
Could you please clarify if I can access the AW created and maintained by OLAP DML via AWM?
I created an AW and some dims and cubes inside it, by using OLAP Worksheet, and cannot see these objects in AWM?
Kind Regards, Neelesh

That is another question. As long as you use AWM to define the dimensions, attributes, measures, and cubes, then you should be fine. And you are correct in saying that the OLAP DML can be used as a calculation language to extend the model defined through AWM. (You can do many other things, too, with this 30-year-old language, but then you really are on your own.)
There are two basic points of integration between the objects defined in AWM and objects you define yourself using OLAP DML.
(1) Calculated measures can be directed to FORMULAs that you define. This, in turn, gives you access to PROGRAMs and other structures. There is also a way, not exposed by AWM, to support calculated attributes (in 11.2.0.2).
(2) Cube Build Scripts can execute OLAP DML commands during a cube build. This gives you a way to link into a forecasting program, for example.
In the other direction you can use the (new to 11.2.0.2) objorg function in OLAP DML to get access to the structures defined through AWM. (This is better than hardcoding the generated names.)
So the real issue is how you edit these calculation objects through AWM. One answer, and it is not a bad one, is through the OLAP Worksheet. The EDIT command will bring up a PROGRAM editor, for example.
For a non AWM answer you could try the old OX program, which is available from here: http://www.oracle.com/technetwork/database/options/olap/olap-downloads-098860.html . This provides a full view of all the objects in an AW. It is quirky, but I like it.

OLAP DML help

In the past I regularly used EXPLANG.HLP. I find it more convenient than the pdf or html equivalents. This is now accessed in 10g via a button on the OLAP worksheet. Does anyone know how I can run 10g OLAP DML Help independently of AWM?

Is it the usage of the host variable syntax within the sql define cursor statement which did the trick ... ":_objecttype" instead of "_objecttype".
I've used the following syntax in olap dml programs in 10gR2 (only 1 filter in the sql statement though)...
"where pr.user_id = :_appuser" ... _appuser is a text variable (not argument) defined locally in the program.

Whitepaper/Info Budgeting/Planning/Writeback via Oracle OLAP DML

Hi,
does anyone know of any whitepaper, manual section, general information regarding writeback, planning, budgeting using Oracle OLAPs DML API? We would like to upgrade our proprietary DataAccess-Layer, which interfaces to Oracle OLAP via the DML-API, to allow writeback.
As said the documentation for this topic seems to be scarce to none.
Just to give an example: it is not possible to write back values to the base measures UNITS_CUBE_SALES/COST/UNITS of the UNITS_CUBE in global AW, since all of them are FORMULA objects. The underlying variable to which you can assign values is in 10g UNITS_CUBE_SALES_STORED, whereas in 11g you would limit the ALL_MEASURES_DIM object to the SALES measure and assign a value to a variable named UNITS_CUBE_STORED. Basically this is information I was fishing out of this forum, but didn't find documented in the Oracle manuals.
Therefor I am wondering, if writeback via the Oracle OLAP DML API is something, which is officially not supported? Or maybe I just didn't look in the right places to find documentation.
BTW: I am looking at this topic from an ISV point of view.
Best regards
Ralf

AWM    OLAP-DML Expression to large?

Hello all!
I have a problem with my AW or with my AW -Manager. I used OLAP-DML Expressions ,and when I write longer Expressions, I got:
oracle.express.idl.util.OlapiException: java.sql.SQLException: Keine weiteren Daten aus Socket zu lesen.
So no more data from socket. I have to restart AW Manager. I can compile the Expressio nwithout error, but when I save the Expression I get the error.
I use AWM 11.2.0.3.0A

Not sure why you are getting error.
You can put this in an OLAP dml program and call that program in your formula (i.e., calculated measure).
Some other suggestions:
(1). Define multiple formulas (or calculated measures) in your AW. For example you can define a separate calc measure for moving total function.
(2). Try to use OLAP Expression Syntax, instead of OLAP dml.
IF...THEN..ELSE logic is done using CASE statements in OLAP Expression Syntax. Moving Total and other time-series functions can be done easily also in OLAP Expression Syntax.
(3). Looks like you probably have a dimension whose members are time-series measures. You can define all the time series measures separately also. Its easier to manage each measure and you can do LOOP_VAR and LOOP_DENSE settings also for better performance.

Help on OLAP DML function – "joinchars"

Hi,
We have built a cube called 'CubeTest' which has a measure called 'TestMeasure' of decimal data type, using Oracle AWM v10.2.0.3.0A.
Now, I am using "Oracle OLAP Calculations v1.2.5", as available on OTN homepage, to define my own calculated measures using OLAP DML for this cube.
I have defined the following two measures (for both, Calculation Type is 'Equation' and both are using free-form equations defined over TestMeasure):
1. Calculated_Measure1
2. Calculated_Measure2
Now, I want to define a third calculated measure in a way that it represents a concatenation of the above two measures suffixed with some standard text.
e.g. A Typical value of the third calculated measure will be like:
Calculated_Measure1 + 'ABC' + Calculated_Measure2 + 'XYZ'
Here, the '+' sign indicates the idea of concatenation.
To achieve the above result, I am using the OLAP DML function "joinchars" to define a free-form equation like the one below:
joinchars(Calculated_Measure1,'ABC',Calculated_Measure2,'XYZ')
Now, the issue is that calculation like the one above, using joinchars is not being created successfully. I tried pre-qualifying (and not pre-qualifying) the names of the calculated measures with the cube name and also experimenting with the “Show” command. Also, once the calculation definition fails to get created, I am not even being able to attach my AW in R/W mode as I get the error as below:
oracle.AWXML.AWException: java.lang.NullPointerExceptionat oracle.AWXML.AW.readAWDefinitions(AW.java:1339)at oracle.olap.awm.dataobject.aw.WorkspaceDO.getModelAW(WorkspaceDO.java:803)at oracle.olap.awm.dataobject.aw.WorkspaceDO.getModelAW(WorkspaceDO.java:749)at oracle.olap.awm.navigator.node.WorkspaceNode.getModelerViewChildren(WorkspaceNode.java:368)at oracle.olap.awm.navigator.node.WorkspaceNode.getChildren(WorkspaceNode.java:341)at oracle.olap.awm.navigator.node.BaseNodeModel.refreshData(BaseNodeModel.java:74)at oracle.olap.awm.navigator.node.BaseNodeModel.dTreeItemExpanding(BaseNodeModel.java:221)at oracle.bali.ewt.dTree.DTreeDeferredParent.__fireExpansionChanging(Unknown Source)at oracle.bali.ewt.dTree.DTreeDeferredParent.setExpanded(Unknown Source)at oracle.olap.awm.navigator.node.BaseNode.expandHelper(BaseNode.java:2186)at oracle.olap.awm.navigator.node.BaseNode.access$400(BaseNode.java:109)at oracle.olap.awm.navigator.node.BaseNode$ExpansionThread.run(BaseNode.java:2136)Caused by: java.lang.NullPointerExceptionat oracle.AWXML.AW.readAWDefinitions(AW.java:1313)... 11 more
For the above issue, I have the following questions to seek your help on:
1. First, obviously, to know what is wrong with the usage of "joinchars" in this scenario.
2. If we use Oracle OLAP Calculations v1.2.5 to define any calculations, and if for some reason, the calculation is not defined successfully, is there any way to see what went wrong and where (this is because if your calculation definition fails, the Oracle OLAP Calculations v1.2.5 utility just exits out without giving any significant information on the reason for failures).
3. When we create any new calculation and then click on “Define Calculations” button, the Oracle OLAP Calculations v1.2.5 utility prompts us with the message “Do you want to update the AW views after creating the calculation (Y/N)? – Can you please help me with the details on the implications of stating a Y or N to this message.
Any help on these questions is much appreciated.
Thanks and Regards,
Piyush

Piyush..
The Error you get on using the rpr command is a display error, its not a functionality issue. Think of this as something similar to the sqlplus buffer overflow issue if you have a pl/sql program which outputs a lot of dbms_output.put_line statements.
So if you get a display error, restrict the cube or the dimensions to a reasonable number and check your output. Example: Take every user dimension and restrict them to a few values... (say, 5 products, 1 channel, 1 location, 1 organization, 2 time periods)..
Rpr <<expression>>
will return the expression for every cell in status.. Depending on the dimensions that the expression is based on, for every dimension depending on the number of values (members) in status, the <<expression>> is evaluated and output'ed.
No of cells in report is Cross product of each dimensions status (statlength).. For example above.. 5*1*1*1*2 = 10 cells.
Shw <<expression>>
will return the expression for the first cell in status.. 1st value (member) in status for every dimension that <<expression>> depends on.
Hence Shw <<expressions>> does not lead to a display error since the output is restricted (small).
Using the OLAP Calc utility to define the formula (the utility uses java olap apis), you may need to do something to protect the single quotes so that the expression gets evaluated with single quotes in the OLAP DML formula.
You can try...
joinchars(CUBE1_CMEAS1, \'ABC\', CUBE1_CMEAS2, \'XYZ\')
If above doesn't work, just ask for help regd how to translate a formula expression containing single quotes (formula is correct in OLAP DML) into the AW via the Spreadheet utility.

How do I view data from OLAP DML program or statement?

Hi
I'm struggling to find any information on this topic anywhere on the net:
How to view data produced by an Oracle OLAP DML program or statement.
Background :
I am using the latest AWM to create and maintain dimensions, cubes and measures. However, I've noticed that AWM, Discoverer OLAP, BI Beans, Excel Plug-In et al only provide a fixed set of formula and expressions.
For example, I wanted to created a Standard Deviation (STDEV) on measure. After much searching I learnt that I could do this by creating a custom measure in AWM by importing a measure defined in an XML dcoument as it's not provided by AWM. The output in Discoverer OLAP on the surface seems to give the correct results, however when drilling from high level to lower level of time time dimension hierarchy Discoverer includes the parent value in the calculation and renders the values incorrect.
My alternative is to use OLAP DML, as it provides a richer range of formuale and calculations possibilities and I was hoping to use this functionality to do create the measures. I have the distinct impression, however, that OLAP Worksheet is the only interface out there to do this.
It seems very primitive and limited with regards to data output, almost like SQL*Plus in many ways.
The burning questions I have are :
1) Do I need to write DML programs to perform these custom measure calculations and add them to cubes or do I import the custom measures via AWM and XML?
2) If the answer to question 1 is DML programming, is there a way of viewing the OLAP data output through a GUI interface without embedding the statements in SQL.
3) Has anyone experienced or noticed the same problem with Discoverer OLAP, AWM Viewer that I mentioned above? i,e, statistical functions performed on whole dimension hierarchy rather than lower levels.
I'm hoping someone out there knows what I am trying to do or get at. Keith, any ideas or suggestions?
Thanks
Kind Regards
Greg

Hi Greg,
There are two ways to achieve what you want. Both require the use of custom calculations which cannot be created via the calculation wizard within AWM. To do this the easiest way is step outside of AWM and use the Excel Calculation utility that is on the OLAP OTN home page:
Creating OLAP Calculations using Excel
http://download.oracle.com/otn/java/olap/SpreadsheetCalcs_10203.zip
Readme
http://www.oracle.com/technology/products/bi/olap/OLAP_SpreadsheetCalcs.html
(Oracle OLAP DML Reference contains a list of all the OLAP functions that can be used to create a custom calculation. http://www.oracle.com/technology/products/bi/olap/OLAP_DML_10.2.zip)
The Excel tool lets you assign your own formula to a measure and then uploads that measure definition into your AW. It is possible to import a custom calculation template into AWM using the menu option on the Calculated Measure node of each cube, but it is safer to use the Excel Worksheet as this directly uses the public XML API and is always best to use a public API rather than hacking XML templates.
There are two types of custom calculation:
1) Formula: using a formula you can directly call any of the OLAP functions. For example to create a measure that returns the standard deviation for a measure then you would enter the following as the formula for your calculated measure:
stddev(sales_revenue, time)
The easiest way to test if the measure is working as expected is to use the data viewer within AWM.
2) Programs - if the function you need is not provided or you want to do special processing to return a result you can create an OLAP DML program which can return a result. To do this use OLAP Worksheet to define the program and add a datatype to the DEFINE statement, such as :
DEFINE PRG_SD_SALES PROGRAM DECIMAL
In the program return the value you have calculated within your program. Within the program you can do just about anything but be aware that your program is going to fire for every cell within your virtual cube so it must be efficient and fast to execute. For a measure then you would enter the following as the formula for your calculated measure:
prg_sd_sales(time, products, geographies, channels).
The actual program code would look something like this:
DEFINE PRG_SD_REVENUE PROGRAM DECIMAL
PROGRAM
argument T_TIME TIME
argument T_PRODUCT PRODUCTS
argument T_GEOGRAPHY GEOGRAPHIES
argument T_CHANNEL CHANNELS
variable D_RETURN decimal
TEMPSTAT TIME, PRODUCTS, GEOGRAPHIES, CHANNELS
do
limit PRODUCTS to T_PRODUCT
limit CHANNELS to T_CHANNEL
limit GEOGRAPHIES to T_GEOGRAPHY
limit TIME to T_TIME
limit TIME add descendants using TIME_PARENTREL
limit TIME keep TIME_LEVELREL 'CAL_MONTH'
D_RETURN = stddev(SALES_REVENUE)
doend
return D_RETURN
END
This code computes a standard deviation the all months within the specified time range, at year level for all 12 months, at quarter level for the three months within the quarter ans returns NA at the month level.
As the code executes within a implicit loop you can only change the status fo dimensions that for part of that implicit by using the TEMPSTAT command. To test the program at the command line use the OLAP Worksheet and the SHOW command to just return one cell of data, DO NOT SIMPLY USE THE RPR COMMAND because you will have to wait for the whole cube to be returned. If you want to use the RPR command make sure you limit your base dimensions first! You can use PRGTRACE to debug your program code it is not working as expected. Again, the easiest way to test if the measure is working as expected is to use the data viewer within AWM, although this will not return debug information so send all your debug output to a file to capture any errors and/or trace the execution flow.
Hope this helps

Creating variables in OLAP DML - 11g

Hi Experts,
My understanding is that the OLAP metadata is exposed to GUI via formulas only. if I create a variable in OLAP DML worksheet, is it possible to expose it to cube view, and awm by formulas/programs etc?
Kind Regards

In OLAP Worksheet you can select 'SQL Mode' from the Options menu and run the SELECT statement there. Alternatively you can run the SELECT statement from inside an olap dml PROGRAM. Here is an example.

Problem with OLAP DML

Dear All,
We are using OLAP DML to work with multi-dimensional data on an Analytic workspace. How do you access pre-stored multi dimensional variables set up in a analytic workspace, using OLAP API's.
How/Is it possible to load Cube data from a multi-dimensional variable ?
How or from where do we setup OLAP WORKSHEET to work with OLAP DML ??
Regards,
Subhankar

Jean-Marc,
I had an email from one of my colleagues in development and has kindly explained some errors in my previous posting. In 10.2 and earlier, relational import/export should do as good a job as EIF, except that these utilities are slower (due to the need to text encode the EIF data) and less granular (you can only export an entire schema at a time).
Fortunately, there is no need to worry about the various objects that comprise and AW. We manage all that for you directly inside the database.
However, the performance overhead is enough that for clients with the know-how, it's usually recommended to use EIF instead. That being said, the particular problem you are having seem extreme since you should not see a "15 minutes" to "hangs" slowdown when using relational import.
Have you tried monitoring the export job via Enterprise Manager to check the wait events which might be occuring when the system hangs? Are there any messages in the alert log?
It might be a good idea to open a TAR with Support to try and diagnose this issue.

CAN i CALL OLAP DML THROUGH JDBC IN JAVA PROGRAM

I HAVE ORACLE V 9.2.0.1.0 AND AFTER CREATING A CUBE FROM ENTERPRISE CONSOLE I HAVE TO GO WITH EITHER SQL PACKAGES OR OLAP DML PROGRAMS ,SO PLS GIVE ME PROPER WAY AND LINK OF SOURCES TO WORK WITH OLAP DML IN JAVA PROGRAMS
CAN I USE AS PREPARED STATEMENT OR CREATE STATEMENT IN JAVA
TO CALL OLAP DML? BECAUSE NORMALLY WE MUST USE OLAP WORKSHEET TO EXECUTE OLAP COMMANDS

The access OLAP objects via Java you have two options. You can code directly against the OLAP API and I think someone has already provided you with the link to the supporting documentation. The OLAP API docs provide worked examples on access OLAP metadata and retrieving OLAP data. However, this is extremely low level coding. An alternative is to use the Business Intelligence Beans. Oracle Business Intelligence Beans enables developers to productively build business intelligence applications that take advantage of the rich OLAP functionality in the Oracle database. OracleBI Beans includes presentation beans - graph and crosstab, data beans - query and calculation builders and persistence services, which may be deployed in both HTML client and Java client applications. OracleBI Beans is seamlessly integrated into Oracle JDeveloper to provide the most productive development environment for building custom BI applications. For more information goto the the BI Beans home page

Specifically on executing OLAP DML see the following example:

Creating CUBE through OLAP DML

Hi
We have a relational database in which we had build cubes . Now we want to convert this into multi dimensional database format . Is it possible to make cubes through OLAP dml and are these cubes accessible via OLAP access packs .
Amar

So far, it has been my understanding and experience that you can't start from "nothing" and have an AW that is capable of using the OLAP API (Java-based access). It always needs the presence of a valid ROLAP cube, and the wizard really does nothing more than create from that the MOLAP equivalent in an AW. I haven't seen anything that lets you do this from only OLAP DML commands. I would love to be wrong, and have a method presented, but all my searching says you can't get there from here.

Query AW with OLAP DML

Hi,
i would like to access and query my cube. Is it possible to do it without building a view? Can I do it just using OLAP DML? Where can I find an example?
thank you

Yes. You can query using OLAP DML. Try this in the OLAP Worksheet (within the AWM)
(Assuming you have attached to the AW)
allstat
limit dimName1 to 'dimValue1'
limit dimName2 to 'dimValue2'
report measName1
Hope this helps,
Swapan.

Creating a Cube using pure OLAP DML

This should be quite simple, but neither reading OLAP_*.pdf nor googling helped me, so maybe you can give me a hint where to look:
I want to create dimensions, populate them, create a cube, and finally populate it, using just OLAP DML (i.e. no DBMS_AW or CWM/CWM2 packages).
1) How can I execute OLAP DML? Right now I'm using sqlplus, wrapping each line in execute dbms_aw.execute(...);
There's some better way, right? :)
2) Can someone give me a link to a simple tutorial, showing how to create a cube et c.? Right now I'm as far as
AW CREATE olaptest1
DEFINE dimfoo DIMENSION TEXT AW olaptest1
DEFINE dimbar DIMENSION TEXT AW olaptest1
SQL SELECT DISTINCT(foo) FROM footable ORDER BY 1 INTO :dimfoo
(the latter one fails, telling me that "quux is not a vaild olaptest1!dimfoo")
3) Have I understood this correctly: I only need an Catalog if I want to work with AWM or DBMS_AWM, not if I just use DML?

I'm not sure exactly why you want to do this.
I guess I didn't explain very clearly :)
We (i.e. the company I work for) creates software (in C++) which needs to work with a lot of data which is in an Oracle-DB.
As the analysis done by the SW would profit (performance-wise) from the layout of the data in an cube, we want to get the data in a cube.
But information like the number of dimensions isn't known beforehand (as that's sth. that's dependent on the site the customer uses the SW on, and can
change with time), the software has to do the creation of dims and the cube itself.
(For the curious ones: http://www.centerpoint.eu.com/ )
And as OLAPI isn't available for C++ (at least afaics), I'd really want to do this in PL/SQL.
If you do use standard form, you then allow yourself the
option of using the various tools later
That's really not needed :)
You can always build the original AW using
AWM, then save the build script it generates, and use
that to do subsequent builds.
Is that build-script in OLAP DML? How do I save it?
BTW, in addition to the SPL INFILE command, there is
the DBMS_AW.INFILE plsql routine, which saves you
some quotes :-).
dbms_aw.execute('infile ''work_dir/my.inf''') vs
dbms_aw.infile('work_dir/my.inf')
I hate superfluous quotes :)
Thanks Jim!

[OLAP DML] display on screen the output while the program is running

Hi,
I'm running a script in AWM that is quite long, and I've placed some few 'show' so that I know what the program is doing, but it won't show on the screen the outputs until the program ends. I guess it writes all the outputs in a kind of buffer and release the content of the buffer at the end of the program.
How could I have it to release this buffer continuously?
Thanks

i think the relational analogy would be an anonymous pl/sql block executing a list of commands while outputting a list of useful dbms_output.put_line log statements:
Just as with SHOW and olap worksheet cmd line, you cant see the running dbms_output log while the pl/sql program is running... you need to wait for it to complete before you can see the log.
You can write to a file and close/exit the file each time or you can write to log table and commit each time but i guess, some such heavy lifting is needed if you want to track the long running process mid-way.
NOTE: For regular operations like dbms_cube.build load/forecast/allocate process/steps, you can always run queries against CUBE_BUILD_LOG etc mid-way. But if it's pure olap dml actions being performed then no neat pre-built handle to check things mid-way exists.

How to generate OLAP DML code or CWM2 code outside of workspace manager 10g

I am using AWM 10.2, where I am creating cubes and dimensions etc. I can export the workspace into XML, but i want more, i want to generate definition of my OLAP, i want to see OLAP DML code for creating my workspace. Anybod has an idea ?
1) How can I generate OLAP DML definition of my existing workspace ?
Second thing is, that I really don't understand the concept of CWM2, what is this good for ? Is my AWM automatically generating some CWM2 statements and executing it ? Where can i see them ? Why do i need another logical CWM definition when I have regular OLAP definition ?
2) What is the role of CWM2 in OLAP ? How can i generate CWM2 code outside of my existing workspace ?

The DESCRIBE command will give you the definition of the object but it won't tell you anything about how objects should be populated. The API for Analytic Workspaces (AW/XML) takes responsibility for both object creation and object maintenance.
What is it that you might want to accomplish by using OLAP DML to create the objects?

Anyone know of a good OLAP DML/DDL tutorial? (and NOT reference guide)

In addition to Analytic Workspace, I am trying to learn how to build cubes using just the OLAP DML / DDL language.
Oracle and others have published a great deal of reference material on the language of OLAP DML / DDL but I can't find any real tutorials that guide me logically thru the process of creating cubes and all that goes with it (defining dimensions, hierarchies, measures, calculations etc..) All the reference material is spread out in bits and pieces and difficult to efficiently learn from. Does anyone have any good OLAP DML / DDL tutorial links they could recommend? Thanks.

Thanks.This is a very difficult task. The OLAP DML/DDL only supports basic multidimensional variables, dimensions (very primitive), and relations. The externally visible cubes and dimensions are a construct of a lot of component objects (a dimension has many primitive dimensions and relations put together to create the higher level DIMENSION that goes with a cube; a cube has multiple variables and other pieces that get put together) in the AW, plus a bunch of metadata objects in the Oracle dictionary.
You really don't want to try to create your own and expect them to interact with the OLAPI interfaces. It is possible to construct your own version of things, but you'd also have to do your own view generation, etc. There are applications out there that are created from scratch, but they are completely from scratch (including whatever interactions they have via SQL). Whatever you create will not work with any of the Oracle-provided interfaces, nor the recently-announced Simba MDX package.
