Interfacing JAVA and OLAP DML

I am not able to get the patch no 2323002 for WinXP/NT/2000. Our project requires to tap the data stored in the cube for analysis and reporting .We plan to use OLAP-DML as a work about.
Can we write OLAP-DML procedures to reply to the dynamic queries of the users and display ther results in JAVA i.e. interface it with JAVA? Also pls tell me how to create stored procedures. i am a new comer to OLAP. Pls help me out.
thanx in advance

Hi,
You should post this to the OLAP forum.
Thanks, Mark

Need help in interfacing Java and MSMQ.

Dear Java Guru,
I am migrating my application from Microsoft Visual Basic to Sun's Java. All the presentation, logic and data layers are already done in Java but we need to retain MSMQ feature as our application server and browsers are using Microsoft OS.
I have check with Microsoft newsgroups and the sample program and libraries they provide requires the use of VJ++. But I do not want to use VJ++ as I am using pure Java. I would be grateful if you can provide me some sample program and the libraries that I need to include in my classpath. Please advise how to interface Sun's Java to MSMQ in this context and any documentation will be helpful.
URGENT !

Hi,
to use MSMQ in java you should embed MSMQ ActiveX in your java application, which gets messages from one queue type and transfer to another type. If you get my freeware API njawin (njawin11.zip) at http://www.simtel.net/pub/winnt/java/ you will find there an example with MSMQ COM control.

Java and OLAP

Hi,
I want to connect to an OLAP server and execute multidimentional queries using Java.
Can anyone tell me if and how this can be done?
Does JDBC2.0 support this?
Regards,

What I usually do is to construct the OLAP SQL (such as in Oracle) and run the SQL via JDBC. JDBC is there to accept a SQL anyway. As long as you you have the right syntax, it will do. Note that it's prefereable to always have a datamart or datawarehouse to cruch the dats or better, a direct tool such as Cognos.

11g - Listing Workspaces in OLAP DML

Hi All,
Is there a way in OLAP worksheet, to list all the workspaces accessible to the user?
It can be done by querying the data dictionary - "select * from all_aws;" but this information should be available in AW and OLAP DML too?
Regards, Neelesh

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.
DEFINE LIST_AWS PROGRAM
PROGRAM
VARIABLE _owner    TEXT
VARIABLE _aw       TEXT
VARIABLE _errortext TEXT
VARIABLE _id_width INTEGER
TRAP ON HADERROR NOPRINT
" SQL Names are 30 characters long
_id_width = 30
" Declare a SQL cursor to get the list of AWs
SQL DECLARE AW_SQL CURSOR FOR -
SELECT OWNER, AW_NAME FROM ALL_AWS
" Open the cursor
SQL OPEN AW_SQL
" Loop through the results
WHILE SQLCODE EQ 0
DO
    IF _aw EQ NA
    THEN DO
           " First loop, so print report headings
           SHOW JOINCHARS(RPAD('OWNER', _id_width) ' ' 'AW')
           SHOW JOINCHARS(RPAD('-' _id_width '-' ) ' ' RPAD('-' _id_width '-'))
         DOEND
    ELSE DO
           " Print aw and owner names
           SHOW JOINCHARS (RPAD(_owner, _id_width) ' ' _aw)
         DOEND
    " Fetch next row into local varialbes
    SQL FETCH AW_SQL INTO :_owner, :_aw
DOEND
" A SQLCODE of 100 is OK,since it means end of records
IF SQLCODE EQ 100
THEN DO
         SQL CLOSE AW_SQL
         SQL CLEANUP
         RETURN
      DOEND
HADERROR:
   SHOW SQLERRM
   SQL CLEANUP
ENDAnd here is what I see when I call it as the GLOBAL user.

OLAP DML - Book

Hi
Can anyone suggest a good book for gettig to grips with OLAP DML?
Thanks
Melanie

As Anthony said, probably the best guides you'll get to the OLAP DML are the online documentation - which also have the benefit of being free! In all honesty, the online docs are about the best & most comprehensive guide to OLAP DML, and these should be your primary source of detailed information on 9i OLAP and OLAP DML.
If you want to buy a book, there aren't any (as far as I'm aware) that are exclusively about OLAP DML (or the old Express 4GL, which is more or less the same), but a couple that might be of interest to you are;
- Oracle9iR2 Data Warehousing by Lillian Hobbs http://www.amazon.com/exec/obidos/ASIN/1555582877
This covers all the 9iR2 BI&W tools, and has a chapter on the OLAP Option and OLAP DML
- Oracle Express OLAP by Sergei Arkhipentov http://www.amazon.com/exec/obidos/ASIN/1584500840/
Not just about Express (it also covers Disco, OWB etc) but has several chapters on Express 4GL
hope this helps

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.

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:

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

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

The most likely explanation is that you have a numeric attribute whose data type precision is less than that of the column it is mapped to. For example if you had an attribute with data type NUMBER(2) and you mapped it to a column with data type NUMBER(5), then you could get this error on load. Note that some of the attributes may not be visible in AWM. The offending SQL statement should be in the OUTPUT column of the CUBE_BUILD_LOG, but you may be able to fix this by just describing the view associated with the dimension. For example, here is the description of a TIME view created in 11.2..

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,

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.

XOQ-01600: OLAP DML error while executing DML "SYS.AWXML!R11_LOAD_DIM"

hi all,
I am trying to do the tutorial Building OLAP 11g Cubes (http://st-curriculum.oracle.com/obe/db/11g/r1/olap/cube/buildicubes.htm), but when I try to "Maintain Cube SALES_CUBE" I get the following error:
An error has occurred on the server
Error class: Express Failure
Server error descriptions:

Can anyone help me?
Thanks,

I have seen this (in 11.1.0.7, I believe) when the metadata cache ("kgl") gets out of synch with the data dictionary. Specifically there is a flag that determines if prefixes get added to dimension members ("use surrogates" in AWM terms) that becomes false instead of true. If you look at the generated SQL in the OUTPUT column of the CUBE_BUILD_LOG you may find that sometimes a prefix is added to dimension members (e.g. "LEAF_LEVEL_" || dim_table.leaf_column) and othertimes it is not (e.g. just dim_table.leaf_column). A workaround if this is the case may be to execute the following (as dba) before building the dimension.
alter system flush shared_pool;

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.

Creating KPI using OLAP DML

Hi all,
How do we develop KPI (Key Performance Indicators) using OLAP DML in AWM 10g R2 (Analytical Workspace Manager)? I am new to this tool. Can anybody help me with a sample code. If there is any other way of implementing KPI in Oracle BI, kindly quote that example as well.
Kieth, if you can answer my question and give me a sample OLAP DML code, i will be more than happy.
Thanks in advance

In 10g this is not quite as simple as 11g. To create a custom measure that calls an OLAP DML program you need to either:
1) Download the Excel Utility from the OLAP home page on OTN:
http://download.oracle.com/otn/java/olap/SpreadsheetCalcs_10203.zip
but check the readme first:
http://www.oracle.com/technology/products/bi/olap/OLAP_SpreadsheetCalcs.html
or
2) Use Warehouse Builder to manage your AWs. OWB allows you to automatically create custom calculations that call OLAP DML programs.
If you look at this posting on the Oracle OLAP Blog you will find an example of how to create an OLAP DML program and reference it from a calculated measure:
