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
Her an example:
This function very well:
if time_utility eq 'CURRENT_DAY' then CUB_MEMBER_TRANSACTION_F_TVON / CUB_MEMBER_TRANSACTION_F_DURATION else -

Is there a limit for the length of Expressions? Or is there a problem with AW -Manager ??
Thanks a lot

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.

IF/ELSE IF in OLAP DML Expression

Is it possible to do an IF/ELSE IF clause directly within my DML Expression?

You maybe right. I could not find the information in the documentation where it is mentioned that the end of line character for a single line expression is '-' character.
I did see the following in OLAP DML documentation.

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..

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.

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.
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

" 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

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.

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;

I have seen this kind of error show up if you rename an object (e.g. a measure) and then make further modifications. Did that happen in your case? If you export the cube to XML, delete it from AWM, and then recreate it from XML, then it may resolve the problem. If not, and if it is preventing your from making progress, then I would open a service request since we usually need to enable tracing to resolve this class of error.

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?

Tip: Improving The Performance Of OLAP DML Table Inserts

Quick Oracle OLAP Tip:
If you need to write the contents of a variable, or a group of variables, to a relational table, you would normally use the SQL INSERT command. Normal practice is to loop round all of the variables' dimension values, inserting the variable values into the relational tables one by one, until the variable has been completely loaded into your database table.
Oracle 9i OLAP however introduces two new commands, SQL PREPARE and SQL EXECUTE (http://download-west.oracle.com/docs/cd/B10501_01/olap.920/a95298/sql5.htm#1027902) , that allow us to prepare our INSERT statement in such a way that it uses bind variables to pass values to the Oracle tables. Bind variables are generally a 'good thing' and reduce the amount of time Oracle has to spend parsing your SQL insert statements. In addition, you can specify additional options with SQL PREPARE to specify 'direct path' insertions (quicker as they bypass the normal SQL engine and directly load data into Oracle blocks), nologging (to eliminate redo log generation), and to nominate individual partitions to load data in to. It's worth noting that there's an error in the current OLAP DML documentation that suggest that any OLAP DML insert operation into an Oracle table locks the entire table, preventing other AW processes from inserting into the table until you commit. This is actually incorrect, and full-table locking only occurs if you use the DIRECT=YES option, which locks the table in the same way that SQL*Loader locks the table as they both use the Direct Path API.
However, an even better solution than using SQL EXECUTE and SQL PREPARE is to use the OLAP_TABLE feature in Oracle 9i (http://download-west.oracle.com/docs/cd/B10501_01/olap.920/a95295/olap_tab.htm#73729) to create a view against your AW variable, then use this view as the source for a "INSERT INTO table SELECT * FROM source" SQL statement, optionally using the /*+ INSERT APPEND */ option if you want to carry out direct path insertions. By using OLAP TABLE and having the SQL engine insert multiple variable values into our target table, rather than having an OLAP DML program loop through the variable and carry out multiple single-row insertions, we were able to increase our write performance by an order of magnitude compared to our earlier SQL INSERT command. One thing to bear in mind though is that, if you are running many copies of the program concurrently, using direct path insertions may well cause lock contention, as each process will obtain an exclusive table lock while the direct insertion takes place. In the case of concurrent processes, it may be better to use conventional path insertions (but still use SQL PREPARE and EXECUTE, or OLAP TABLE) as these only require row-level exclusive locks.

you can use Execution plain
http://stackoverflow.com/questions/7359702/how-do-i-obtain-a-query-execution-plan
and add index.
Index according to the fields you ask queries can improve performance greatly larger!
You can use the statistics for building indexes:

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:
