Delete dimension/cube in Analytic Workspace
Hello, I've created some dimensions and cubes in an analytic workspace using DBMS_AW package. But, How can I delete these objects using a similar methodology? I have not found any procedure like CREATE_AWDIMENSION/CREATE_AWCUBE that helps me to delete the object.
Thanks by your help.
In 9.2x code stream, having it not in cwm2/all_olap2_dimensions means it will be invisible/unaccessible to the OLAP API but, as you point out, it still exists in the AW, and as such, it still exists in all_olap2_aw_dimensions.
The early comment was a way to potentially "work around" the inability of no automation to "fully" delete it, by suggesting a way to "partially" delete it so as to "hide" the dimension from the OLAP API, without actually deleting it (or any of it's storage, obviously) from the AW.

Dimension updates in Analytic workspace:Materialized views?
We are using the 10g version of Oracle OLAP. We have 1 materialized view joining with our custom table and forming 1 source view per dimension. We load the cube programatically by refresh the dimension materialized views, followed by loading fact data to views against cube and then the actual workspace and cube creation..
Question is :
1) Do dimensions get loaded to analytic workspace only when the analytic workspace is created (programatically or maintain dimension via AW)?
2) Assume we do not create the analytic workspace programatically or do not do a maintain dimension. In this case willl the dimensions in the analytic workspace get refreshed any time the data in source tables in the materialized view or custom table used in dimension source view change?
Please advise.
Thanks,
SudipIf the data source changes for OLAP 10g then you must maintain the AW/ dimensions/cubes. There is no ability to check if anything in the source has changed.
If using 11g, then you can use the MV refresh capabilities to maintain your AW (if your model conforms)...MV refresh features detects changes in the source tables.
Hope I understood your question correctly. -
Cannot drop cube or analytic workspace due to ORA-37409
The error is ORA-37409: cannot delete or truncate AW used by CUBE ORGANIZED table.
This seems very closely related to the bug discussed in this thread: Drop cube organized table
We need to drop and rebuild a cube due to a design change. It looks like there are some CR$ tables related to the cube preventing the drop.
We cannot drop the CR$ table, nor can we drop the cube, nor can we drop the analytic workspace. We have tried disabling materialized view refresh on the cubes (which works but leaves the CR$ tables out there). We have tried the drop using dbms_aw.aw_delete and with dbms_cube.import_xml (to remove everything). No such luck.
Is there a workaround you can give me that will allow us to drop the CR$ tables? Or a workaround that will allow us to drop the workspace?Update:
Our last attempt to drop the analytic workspace did remove almost all OLAP metadata. However, there were still rows in sys.olap_tab$ with object IDs relating the problem CR$ tables. In a test database, we confirmed that deleting these rows does allow us to drop the CR$ tables that cannot otherwise be dropped. However, running DML against a sys-owned table like this is unwise at best, and certainly an unsupported workaround (unless we can get Oracle's blessing to do it).
We may go through MOS and see if Oracle can provide a one-off patch for the bug listed above, to correct this situation. Or perhaps they may be able to provide some other direction.
This puts us in a situation where our only immediate option may be to uninstall the OLAP option and reinstall it. -
Hi
I am completely new to Oracle OLAP.
I have installed Oracle 10g(10.1.0.2) with OLAP option enabled.
I would like to create some cubes using Analytic Workspace manager. When I look into Oracle HomeIntegrated Management Tools, I wouldn’t find Analytic Workspace manager.
Do I need to install Analytic Workspace manager separately? If it comes along with the oracle suite, what did I want to do to have analytic workspace manager in my machine?
Please help me.
Thanks,
DeepaHi
Thanks for the info.
I like to get more information regarding the same in version 10.1.0.2

Creating a DWMQY DIMENSION using Analytic Workspace Manager
Hi everyone,
I need some help creating a "time aware" (DAY, WEEK, MONTH, QUARTER, and YEAR) dimension using Analytic Workspace Manager.
Let me give you some background. I'm coming from a traditional "Oracle Express" OLAP background where all our data is stored in cubes and these are defined, populated and operated on using OLAP DML, there is no SQL or traditional relational tables involved.
I now want to pull data from relational tables into some OLAP cubes and am using Analytic Workspace Manager to do this (maybe this is not the best way?)
Let me explain what I'm trying to achieve. In OLAP worksheet I can type the following DML commands:
DEFINE MY_DAY DIMENSION DAY
MAINTAIN MY_DAY ADD TODAY '01JAN2011'
What this will do is create a "day dimension" and will populate it with values for each and every day between 1st Jan 2011 and today. It will be fully "time aware" and thus you can use date functions such as DAYOF to limit the MY_DAY dimension to all the Fridays etc. Similarly if I define a "month dimension" there will be an automatic implicit relationship between these two dimensions, this relationship and time aware cleverness is built into Oracle.
However, a dimension defined using DML commands (and indeed all objects created using DML language) is not visible in Analytic Workspace Manager (as there is no metadata for them?) and for the life of me I cannot work out how to create such a dimension using AWM. If I create a "Time Dimension" then, as far as I can tell, this is not a proper time dimension but merely a text dimension and I, presume, I have to teach it time awareness.
Can anyone help me? I have no issues creating, and populating cubes from relational tables using Analytic Workspace Manager, the only issue I have is creating a "proper" time aware dimension.
Many thanks in anticipation.
Ian.When a dimension is of type "TIME" in AWM, then for each member of that dimension, you need END_DATE and TIMESPAN attributes in addition to the key column and description column.
So in your case, if there are 5 levels: DAY->WEEK->MONTH->QTR->YEAR
then you will need atleast 15 columns in your source sql table/view
or 20 columns if you have separate column for description.
For example the columns in your source table/view could be:
DAY_ID,
DAY_DESC,
DAY_END_DATE, (which will be that day's date)
DAY_TIMESPAN, (which will be 1)
WEEK_ID,
WEEK_DESC,
WEEK_END_DATE,
WEEK_TIMESPAN,
MONTH_ID,
MONTH_DESC,
MONTH_END_DATE,
MONTH_TIMESPAN,
QTR_ID,
QTR_DESC,
QTR_END_DATE,
QTR_TIMESPAN,
YEAR_ID,
YEAR_DESC,
YEAR_END_DATE,
YEAR_TIMESPAN
Just "map" this table/view to the 5-level time dimension in AWM.
NOTE that behind-the-scenes lot of useful structures are automatically defined to support time-series measures,
and there are lot of calculation templates available also.
Since you came from Express background, I have to say that try to use new OLAP Expression Syntax when creating calculated measures instead of OLAP DML.
Its very rare these days that we need OLAP DML.

Analytic Workspace Manager possible bug: Maintain Cube hangs
Hi All,
I am a newbe, I have been following the tutorial "Building OLAP 11g Cubes". http://www.oracle.com/technology/obe/olap_cube/buildicubes.htm
After the step "Maintain Cube SALES_CUBE", I got the information box "Loading facts for cube SALES_CUBE"...on the screen for the last 4 hours.
Is this normal? Should I kill the process and start again?
I am running Oracle 11g Enterprise Edition Release 11.1.0.7.0 on a Virtual Machine with Windows Server 2008 Standard SP1 with 1GB RAM.
The Analytic Workspace Manager is 11.2.0.1.0 running on a Windows XP SP3.

This is too bad, so far I've been loving 11g Olap as compared to 10g Olap. But now 11g is starting to crop up these bullshit bugs as well. I guess OLAP is still too crappy to rely on for production....good thing I won't recommend a rollout of this product to my clients. It's a great tool for having fun with development, but using Oracle Olap + AWM in a real company is career suicide.

TWO ANALYTIC WORKSPACES - SAME DIMENSION HOW TO REFER
Hi All,
I have two analytic workspaces MSD.MSD3765 and MSD.MSD13834. I attach both of them using the following.
begin
dbms_aw.execute('aw attach MSD.MSD13834 ');
dbms_aw.execute('aw attach MSD.MSD3765;');
code to refer a dimension with the same name which exists in both the aws
dbms_aw.execute('aw detach MSD.MSD3765');
dbms_aw.execute('aw detach MSD.MSD13834;');
end;
I would like to refer a dimension dmentry, which exists in both the aws. Can some one help me out regarding this? I tried MSD.MSD3765.dmentry and MSD.MSD13834.dmentry. It isn't working.

Deployment of Analytic Workspace
Hi,
I have a query regarding the deployment of an AW in various environments like dev, test and live.
When we first create the AW in dev environment, we specify an AW name and the tablespace to be allocated for that particular AW. For deploying the AW in different environment, we use the XML template that is exported from the AW using 'Export Analytic Workspace to Template' option. But while creating the AW from template, there is no option to specify the tablespace for the new environment.
Could anyone please help me how tablespace can be specified while deploying AW in other environments.
Thanking in advance,
MainakThis is a bit of a hack, but it will work
Towards the end of the XML template file you should see an entry something like this.
<AW
Name="MY_AW"
Version="11.2">
</AW>The name of the AW will obviously be different, and the version may be different as well. It doesn't matter because you will just delete the section from the XML document.
Now in AWM you first create an empty AW using the simple "Create Analytical Workspace..." option. This will allow you to specify a tablespace. Once you have done this you select "Create Analytical Workspace From Template..." and import your objects into the AW you just created. Note that you must create an AW with the same name as the original as it is embedded into the XML for the cubes and dimensions.
The more sophisticated version of this is to delete the AW section above and then add a header to the XML template
<!DOCTYPE Metadata [
<!ENTITY % BIND_VALUES PUBLIC "OLAP BIND VALUES" "OLAP METADATA">
%BIND_VALUES;
]>Finally you replace all occurrences of your AW name with the string
&AW_NAME;For example, instead of
<AWPrimaryDimensionOrganization
MVOption="NONE"
HierarchyConsistencyRule="STAR_CONSISTENT"
AddUniqueKeyPrefix="False"
AW="MY_AW">you would have
<AWPrimaryDimensionOrganization
MVOption="NONE"
HierarchyConsistencyRule="STAR_CONSISTENT"
AddUniqueKeyPrefix="False"
AW="&AW_NAME;">You can see this type of XML if you export a single cube or dimension to a template. I don't know why AWM doesn't let you do the same thing for the whole AW. -
We have an AW with cubes refreshing every day. Fast solve of these cubes with incremental set of data finishes usually within an hour or two.
Our recent requirement needs for us to remove some old facts as well as a few dimension members. The facts can be cleared but we noticed that deleting dimension members (using synch load) is causing a full cube solve due to changed relations. With the amount of data existing in this AW, full solve takes about 2 days to complete. Deleting dimension members for which we never ever loaded any facts also causes the same result as above.
I was wondering if there is any way we can delete these dimension members without triggering a full cube solve.
Another question is if it is possible to update dimension primary keys inside of the AW?
Any help is really appreciated.
Database Version 11.2.0.3These types of questions have been answered in the past by David Greenfield.
There are two ways to delete a dimension member through commands.
(1). OLAP dml command "REMOVE_DIMENSION_MEMBER" explained here: http://docs.oracle.com/cd/E11882_01/olap.112/e17122/dml_commands_2042.htm#OLADM2692
OR
(2). dbms_cube.build command:
exec dbms_cube.build(q'! "TIME" USING (DELETE FROM DIMENSION WHERE MEMBER = 'APR-2011') !');
Take a look at this old post, where David Greenfield explained it.
https://forums.oracle.com/message/9426946
There is no way to rename a dimension member in a standard-form analytical workspace. There is "MAINTAIN RENAME" olap dml command, but it will not work with dimensions created through AWM. You can add the new dimension member, then copy cube data associated with old/existing member to the new member and then delete the old member.
For cube copy data example, take a look at these old (15-Feb-2011, 16-Feb-2011 and 17-Feb-2011) posts by David Greenfield:

Creating an Analytic Workspace
Hi,
i want to create an analytic Workspace without the AWM, but I want to see the Dimensions Cubes, etc what I create in the AWM. I Work with the AWM 10.2.0.3.0. What packages must I use for it? Someone say I must use the cwm2 and the dbms package an otherone say that I must use the AW/XML package.
Give it a Example for Creating an AWM??
ThanksIf you want to create the AW without manually sitting in front of the AWM, Oracle prefers you to use the AWXML and AWAction packages in Java. If you have the AWM installed on your machine, you have the jar files you need in the AWM install directory.
