Oracle 9i Olap Api XADEMO

How can I run the XADEMO sample code available in $ORACLE_HOME\OLAP\olapi\sample...? The Java class files have been generated but do not know how to proceed?

With the limited details provided, I believe your best place to start on customer churn studies would be with the Data Mining technology rather than OLAP. Please post your question to the following forum on OTN:

Good-luck!

Oracle 9i 9.2.0.5 olap api

HI guys
i patched my oracle9i 9.2.0.1 to 9.2.0.5
and run catpatch.sql to upgrade olap
but when i try to use olap api
MdmMetadataProvider mp = null;
mp = (MdmMetadataProvider) dp.getDefaultMetadataProvider();
it always throws that its mp is null
althougth i validate all cubes and dimensions
(note : i try my code from oracle olap api book
and on sales history schema )
so what is wrong.
note: when i try to use jdev 9.0.3.3 and BI
to build olap connection it do it and it sees all
DIMS and CUBES...., so the problem in olap pi
and u said that this patch will solve all my problems
thanks.

An error occurred during olap API metadata retrieval. This is probably caus

this is what i have done so far. i really nead some help asap!!!
1. Install Oracle 9i Release 2 (9.2.0.1) Enterprise Edition with the General purpose database configuration (Data warehouse works as well). At the end of the installation I chose the password management button to change passwords for the few necessary accounts: SYS, SYSTEM, OLAPSYS, SH.
2. Download the p3948480_9206_WINNT.zip from metalink, the 9.2.0.6 patchset
3. Shut down any existing Oracle9i database instances with normal or immediate priority. Stop all listener and other services running in the Oracle home directory where you want to install the patch set.
4. unzip the content of thepatch to a temp directory
5. start setup.exe under the temp directory (it will start the Oracle Universal installer 10.1.0.3)
6. install the patchset to your Oracle home, selecting the source in the temp_dir\stage\products.jar file
7. review carefully the post-installation tasks for the patchset:
Review the following sections before upgrading a database (quote from the patchset html readme):
8.2.1.1If JServer is part of the installation ensure that there is at least 10 MB of free space allocated to the SYSTEM tablespace.
8.2.1.2 Check XDB Tablespace Size
For RAC installations, ensure that there is at least 50 MB of free space allocated to the XDB tablespace.
8.2.1.3 Set the SHARED_POOL_SIZE and JAVA_POOL_SIZE Initialization Parameters
Set the value of the SHARED_POOL_SIZE and the JAVA_POOL_SIZE initialization parameters as follows:
Start the database:
SQL> STARTUP
If necessary, enter the following command to determine whether the system uses an initialization parameter file (initsid.ora) or a server parameter file (spfiledbname.ora):
SQL> SHOW PARAMETER PFILE;
This command displays the name and location of the server parameter file or the initialization parameter file.
Determine the current values of these parameters:
SQL> SHOW PARAMETER SHARED_POOL_SIZE
SQL> SHOW PARAMETER JAVA_POOL_SIZE
If the system is using a server parameter file:
If necessary, set the value of the SHARED_POOL_SIZE initialization parameter to at least 150 MB:
SQL> ALTER SYSTEM SET SHARED_POOL_SIZE='150M' SCOPE=spfile;
If necessary, set the value of the JAVA_POOL_SIZE initialization parameter to at least 150 MB:
SQL> ALTER SYSTEM SET JAVA_POOL_SIZE='150M' SCOPE=spfile;
If the system uses an initialization parameter file, if necessary, change the values of the SHARED_POOL_SIZE and the JAVA_POOL_SIZE initialization parameters to at least 150 MB in the initialization parameter file (initsid.ora).
Shut down the database:
SQL> SHUTDOWN
8.2.2 Upgrade the Database
After you install the patch set, you must complete the following steps on every database associated with the upgraded Oracle home:
Log on as a member of the Administrators group to the computer where the Oracle components are installed.
Use SQL*Plus to login to the database as the SYS user with SYSDBA privileges:
sqlplus /NOLOG
CONNECT SYS/password AS SYSDBA
Enter the following SQL*Plus commands:
SQL> STARTUP MIGRATE
SQL> SPOOL patch.log
SQL> @ORACLE_BASE\ORACLE_HOME\rdbms\admin\catpatch.sql
SQL> SPOOL OFF
Restart the database:
SQL> SHUTDOWN
SQL> STARTUP
Run the utlrp.sql script to recompile all invalid PL/SQL packages now instead of when the packages are accessed for the first time. This step is optional but recommended.
SQL> @ORACLE_BASE\ORACLE_HOME\rdbms\admin\utlrp.sql
12. Install JDeveloper 9.0.4 (download it from OTN and just unzip it in a directory ... it doesn't require an oracle home)
13. Install BI Beans 9.0.4 (download it from OTN as well), run the setup.exe that comes with it and in the destination oracle home select the directory where you installed JDeveloper and give an oracle home name to it)
14. Install the BIBDEMO schema:
Create a directory on the computer that is running the Oracle9i database. This install_home directory is the location to which you will upload the data files that are required to build the BIBDEMO schema.
On the computer where BI Beans is installed, locate the bibeans_home\bibdemo_schema folder (where bibeans_home is the root folder of your BI Beans installation). Copy all of the files found in this folder to the install_home folder on your server machine.
Open a DOS prompt and navigate to the install_home folder.
Run bibdemo.bat to install the schema, using the following syntax:
bibdemo.bat <path to Oracle database files >
For example, for an instance named my9iService, enter the following:
bibdemo.bat D:\OraHome1\oradata\my9iService
You are prompted for the password for the sys as sysdba user.
The script takes approximately 15 minutes to run, depending on the machine specifications. It is normal to see some error messages while the script is running. In addition, when materialized views are being created in the database, the script will appear to stop; this is also normal. A clear message will tell you when the script has completed.
The log files (*.log) that are generated by the installation script are stored in the folder from which you ran the script.
Here's what
bi_checkconfig.bat -h ana -po 1521 -sid proiect -u bibdemo -p bibdemo -q

WHAT AM I MISSING? SHOULD I USE AW MANAGER? OR DO I NEED TO CREATE AN AMNALITIC WORKSPACE???
WHAT ARE THE STEPS TO CREATE A GOOD METADATA????

Hi,
The issue here is if the whole catalog is corrupt or just one schema. So to try and determine the status of the catalog I would try:
1) Using OEM remove all the objects you created
2) I presume you created your database using the Database Configuration Assistant? You should have used the warehouse template
3) Make sure the following accounts are unlocked and also not expired : SH, OLAPSYS
4) Make sure the password for the SH schema is SH
5) Make sure the password for the OLAPSYS account is manager
6) Install the BIBDEMO schema that is shipped with BI Beans. This in the jdev_home/bibeans/bibdemo_schema
The installation process will remove SH schema from the OLAP catalog.
7)Once this is installed use JDeveloper to see if you can create a crosstab or graph.
8) If the BIBDEMO schema works try creating your new schemas one at a time.
9) Make sure the if you define the a dimension as type time it has END_DATE (column type DATE) and TIME_SPAN (column type number) defined. Otherwise don't define the dimension as type time.
Hope this helps

XML Sax Exception with 9.2.0.5 express*.jar files for Olap API

I was using the olap_api_92.jar that
came with jdeveloper for the olap api and having a coding problem.. In trying to see
if I could resolve the previous problem, I set my classpath to use the jar files provided with the 9.2.0.5
install for AiX.. all beginning with express*.jar
I now get an XML parsing error that I can't fix..
which jar is good, the olap_api_92.jar seems to work..
Help!

Does the user have to be the owner of CWM2 objects to access them via OLAP API?

Hi,
What are required for RDBMS users to use OLAP API? Regarding page 6-9 of Oracle9i OLAP User's Guide 9.2.0.1, following access rights are required.
CONNECT role
QUERY REWRITE system privilege
SELECT privilegs on the database objects containing the data to be analyzed
So, I created a new user TEST1 and granted all the priviges above. Then I tried to create a new crosstab using New Crosstab Wizard in JDev903_pre(OLAPConnecton is using TEST1). When I choose a measure that is created in CWM1, I could create a crosstab without problem. But when I tried to create a crosstab from a measure that is created in CWM2 by OLAPSYS user, I recieved the following error.
BIB-9509 Oracle OLAP did not create cusor.
oracle.express.ExpressServerExceptionError class:OLAPI
Server error descriptions:
DPR: Unable to create server cursor, Generic at TxsOqDefinitionManager::createCursorManager
OES: ORA, Generic at TxsRdbSelectStatement:execute()
The curious thing is that I can create a crosstab from the same measure if I use another connection that uses OLAPSYS. Does the user that connects to CWM2 using OLAP API have to be the owner of those CWM2 objects?
Thank you.
Best Regards,
Seiji

The user does not have to be the owner of the cwm2 objects to access them. Access to cwm2 objects is based on database security. Therefore, if the user is not the owner of the object (if user is the owner, they obviously have access to the object), then as long as the user has been granted access to the underlying physical object (i.e., the table the dimension or cube has been mapped to), the user will be able to access the object.

Unable to select OLAP API metadata

I am using oracle rdbms 9.2.0.5
Initially I was able to view BIBDEMO schema cubes using cubeviewer. I also created my own cubes using CWM2 API and was able to view through the bibeans. All of sudden it stopped working and I am currently unable to even view the demo cubes in BIBDEMO schema using cube viewer, it throws a "red bell with no error message" dialog.
I validated the entire OLAP catalog using the CWM2 API, all the objects are valid.
I do not have a time dimension and any AW cubes.

How can I debug this issue.
Thank you,
Senthil

I figured what the problem is, I missed one of the invalid objects in my OLAP validation log file when I scanned before.
As part of another issue (Issue #1), I dropped and recreated some dimensions. But did not reattach those dimensions to the cube. So in the log, that particular cube was marked as invalid with the error "no dimensions".
FYI - (Issue #1)
When creating dimensions, by mistake I mapped some of the fields using CWM2 map table API to a VIEW. The CWM2 validation API, validated these dimensions and marked them as valid.
But from the query builder I was not able to progress forward from the layout panel to the dimension panel, it will just sit there without throwing any errors. Once I changed the view to the base table in the dimension definition, the querybuilder started working.
Thank you,
Senthil

Data access through the OLAP API

We have created a number of Cubes from the AWM, and access the cubes from a web based application through the OLAP API. The cubes have both base measures and custom measures. Custom Measures are computed by creating the source object for given Formula Expression. The application works fine for a single user, but when a same cube is accessed concurrently by multiple users, we get the TransactionalObjectInvalidException when we call the MdmMeasure.getSource() function for the custom measures.
Since each individual users have individual contexts and the static methods are properly sunchronized, we havent not been able to trace this error so far. The exception is thrown by oracle.olapi.data.source.ImmutableDefinition.checkValidity() API method. Error Trace is:
oracle.olapi.transaction.TransactionalObjectInvalidException

Hi, yes, there are at least two known ways:
1. if you happen to have a UCCX premium, you can create an HTTP application that serves up the prompt file,
2. you can try to access the prompt file like this: http://<uccxip>:9080/prompts/dirname/promptfilename.wav

Oracle 11g OLAP & SQL

Hi All
Our company is in the process of doing a POC warehouse where we are using Oracle OLAP extensively for summary management. I have been tasked with porting all our existing reports (Cognos) from using an Informix backend to start using Oracle. The OLAP team has created some cube views for me but Im struggling to get my around how Im going to use them for reporting purposes.
Example
1) Im using the following sql (abbreviated) to get my data:
select
v_product.product_description.
v_product.level_name,
v_sales.sales,
v_sales.calc_measure
from v_product, v_sales, v_location, v_time
where ... all the joins....
v_product.level_name in ('DEPARTMENT', 'CLASS')
and v_location.level_name = 'TOTAL'
and v_time.level_name = 'TOTAL'
2) This brings back data that looks like:
product_description level_name sales calc_measure
MEAT DEPARTMENT 232323 23.56
POULTRY DEPARTMENT 43444 35.23
BEEF CLASS 232323 23.56
CHICKEN CLASS 67455 35.23
LAMB CLASS 73444 23.56
PORK CLASS 55555 35.23
3) I need to create a list report thats grouped by department and for each department shows all the classes but off the data above is very difficult. I cannot just select the all the class values and then do the aggregation in the report as there is a calculated measure so I need to select the value for that level from the cube view. Is it possible in one sql statement or will I need more?
Thanks for any ideas

Dave thanks for your reply. Please excuse my poor example this was my first day using cube views and I cannot login to my work setup from home so going by memory alone.
To answer your question
1. We are using 11g AW
2. I don't remember the exact cube view names but not relevant to my question (I think)
3. Alas the oracle forums don't support much formatting else I would have provided an ascii example. I have uploaded the sample report output here http://i279.photobucket.com/albums/kk145/angusgoosemiller/sample.gif
Better Example
1. From what I can gather if your query more that one level in the same dimension from a cube view you get the results denormalized as rows. So effectively for my report I what the department and class levels from the product hierarchy where class is a child of department and some relevant measures one of which is a calculated measure. If I select this from the cube view I am getting results in the form:
DEPARTMENT LEVEL ... row values
DEPARTMENT LEVEL ... row values
CLASS LEVEL ... row values
CLASS LEVEL ... row values
2) My report is a list report that is grouped by department and for each department all the class records are displayed with the measures. There must also be a department total for every department level and a grand total for the report. If the calculated measure was not included I could just return all the class records as the there is a department attribute defined that is also in the cube view and calculate all the department values dynamically in the report. However due to the calculated measure and probably as a best practice from a performance/redundancy perspective I only want to select from the cube view in its aggregated form like is currently happening.
3) From a report design perspective this provides some challenges as relationally hierarchy levels are normally modeled as columns and we use to process calculated measures dynamically in the report. Going forward we would like all the calculations etc happening in the OLAP engine.
4) So basically the way I see it I need the following from the cube:
4.1) The department records
4.2) The class records
4.3) the department total records
4.4) the grand total record for all departments
Can I get that in one SQL statement in such a manner that I can produce a report? How would an oracle based reporting solution get the data, via sql or directly from the cube via the olap api.
Thanks for your help I really appreciate any advice!
Cheers
Angus

Oracle discoverer olap and 11g olap

Does anyone know if i can use disco plus olap against an 11g database cube. currently with my patch level it definately doesn't work as i cantwven select a catalog to report on but if i add patches will it work? and is it certified?
i have read the following and it still isn't clear
Doc ID: 808276.1
and
Doc ID: 727948.1
please help
Thanks

Oracle makes it a general policy not to announce things in future releases, even bug fixes, without due approval from senior management. This puts Oracle developers in the unfortunate position of not being able to pass on information in forums like this, which is why you are not able to get a straight answer to your very reasonable question.
It is true that full support and certification for D4O and the Excel Add-In did not make the 11.1 release. This was for two reasons.
(1) On the OLAP Option side there were so many changes to the metadata layer in 11.1 that there simply was not time to fix all the bugs. As I said earlier, D4O basically works against 11.1, but the OLAP group did feel confidence in its stability and performance. I can say that many D4O related OLAP bugs were logged and targeted for 11.2 and that stability and quality is the number one goal for the 11.2 OLAP release.
(2) The teams that worked on Discoverer classic, Discoverer for OLAP, and the Excel Add-In were moved on to new projects following the acquisition of Siebel. You can see the statement of direction here .
Of these clearly the latter is the bigger problem. Oracle OLAP itself is committed to maintaining support for existing interfaces and the OLAP API (used by D4O) has not been deprecated. In fact it was the basis of much of the work in 11g.

How to use olap api

i have generated cube with oracle 9.2.0.1.0 with star schema and now i want use directly access olap api from java programs ,what is the steps pls suggest me?
i am little bit confused about that
is there any examples with java progarams

Wrong forum, refer to the OLAP forum:

It appears to be missing metadata. Since you are trying to get the schema, this is most likely a field that is required but not present (something silly, like labels). Try the following scripts posted below that verify metadata.
When creating solved level hierarchies, all of these dimensions require 4 special dimension attributes. All 4 of these dimension attributes require a level attribute to be mapped to a populated column in each of the solved hierarchies.
The 4 special attributes are:
GID
PARENT_GID
ET
PARENT_ET.
You can check if these attributes exist with the following query:
SELECT DA.OWNER,\n\
DA.DIMENSION_NAME,\n\
DA.ATTRIBUTE_NAME,\n\
NVL(DA.DISPLAY_NAME, DA.ATTRIBUTE_NAME),\n\
NVL(DA.DESCRIPTION, DA.ATTRIBUTE_NAME),\n\
(CASE WHEN D.DESCRIPTOR_VALUE = 'Long Description' THEN 4\n\
WHEN D.DESCRIPTOR_VALUE = 'Short Description' THEN 5\n\
WHEN D.DESCRIPTOR_VALUE = 'End Date' THEN 1\n\
WHEN D.DESCRIPTOR_VALUE = 'Time Span' THEN 2\n\
WHEN D.DESCRIPTOR_VALUE = 'Year Ago Period' THEN 3\n\
WHEN D.DESCRIPTOR_VALUE = 'Grouping ID' THEN 6\n\
WHEN D.DESCRIPTOR_VALUE = 'Parent Grouping ID' THEN 7\n\
WHEN D.DESCRIPTOR_VALUE = 'ET Key' THEN 8\n\
WHEN D.DESCRIPTOR_VALUE = 'Parent ET Key' THEN 9\n\
ELSE 0\n\
END)\n\
FROM ALL_OLAP2_DIM_ATTRIBUTES DA,\n\
all_olap2_entity_desc_uses edu,\n\
all_olap_descriptors d\n\
where\n\
DA.OWNER = EDU.ENTITY_OWNER (+)\n\
AND DA.DIMENSION_NAME = EDU.ENTITY_NAME (+)\n\
AND DA.ATTRIBUTE_NAME = EDU.CHILD_ENTITY_NAME (+)\n\
AND EDU.DESCRIPTOR_ID = D.DESCRIPTOR_ID (+)\n\
ORDER BY DA.OWNER, DA.DIMENSION_NAME, DA.ATTRIBUTE_NAME
For these 4 attributes, it's not enough that they just exist, (note you can name them whatever you want) but they also have to be marked as the appropriate type as per the above SQL.
Note also that the above SQL checks for other specially marked attributes such as Long/Short Description and End Date/Time Span. These attributes can exist without being marked as such (and can even be missing completely), and OLAP API will still function. However, I believe the OLAP API functions "better" if these attributes exist and are marked as special.
The below SQL will check your column mappings for all attributes. (As a general rule, you shouldn't have to worry too much about mapping any CWMLITE logical entity to a valid table/column, because the CWMLITE API should catch if you don't use a valid table/column.)
select owner,\n\
dimension_name,\n\
hierarchy_name,\n\
level_name,\n\
attribute_name,\n\
table_owner,\n\
table_name,\n\
column_name,\n\
(case when dtype = 'NUMBER' then 0\n\
when dtype = 'DOUBLE' then 5\n\
when dtype = 'FLOAT' then 4\n\
when dtype = 'DATE' then 7\n\
else 1 end)\n\
from\n\
all_olap2_dim_level_attr_maps\n\
ORDER BY OWNER, DIMENSION_NAME, HIERARCHY_NAME, ATTRIBUTE_NAME
Finally, note that any hierarchy which you map as coming from an AW will be a solved level hierarchy.

Read existing cubes with Java OLAP API

Hi,
i am new to the Oracle OLAP API and i have a question for which a do not find the answer in the documentation..
I need to access all existing cubes in a database, get the names, the corresponding dimensions etc.
There is no problem in reading the dimensions their hierarchies, the measures an so on. But i found no method or class to read out the information about cubes (names, dimension).
The only thing i found in the documentation to get a cube was over a MtmMeasureMap, but when i call this method i get the exception: Not supported by server version ORAOLAP10.2.0.1.0
Any hints?
Thanks

In current releases, the OLAP API is primarily a query API. Queries can include measures from multiple cubes, so there is no real purpose for a cube object. Therefore there is no Cube class in the Mdm logical metadata package.
Cubes are useful in OLAP mappings, and there is an MtmCube class in the Mtm mapping metadata package. It is possible to navigate between Mdm and Mtm objects. The code that follows prints out the names of all of the cubes and the names of their dimensions.
I don't understand the "Not supported by server version" error that you got. This sample code works for me in 10.1.0.4, and I expect it would work in 10.2, too.
Geof
MdmMetadataProvider mdp; // given
Hashtable cubes = new Hashtable();
MdmSchema rootSchema = mdp.getRootSchema();
Iterator subSchemas = rootSchema.getSubSchemas().iterator();
collectCubes(rootSchema, cubes);
while (subSchemas.hasNext())
collectCubes((MdmSchema) subSchemas.next(), cubes);
// enumerate cubes
Enumeration cubeList = cubes.keys();
while (cubeList.hasMoreElements())
MtmCube cube = (MtmCube) cubes.get(cubeList.nextElement());
System.out.print(cube.getName() + ": ");
Iterator dimensionMaps = cube.getDimensionMaps().iterator();
boolean first = true;
while (dimensionMaps.hasNext())
MtmDimensionMap dimensionMap = (MtmDimensionMap) dimensionMaps.next();
MdmDimension dimension = (MdmDimension) dimensionMap.getMdmSource();
if (first)
first = false;
else
System.out.print(", ");
System.out.print(dimension.getName());
System.out.println();
void collectCubes(MdmSchema schema, Hashtable cubes)
Iterator measures = schema.getMeasures().iterator();
while (measures.hasNext())
MdmMeasure measure = (MdmMeasure) measures.next();
MtmMeasureMap measureMap = measure.getMeasureMap();
MtmCube cube = measureMap.getCube();
// See if we have already visited this cube for another measure
String id = cube.getID();
if (null == cubes.get(id))
cubes.put(id, cube);

OLAP API to get child nodes ?

Hi, I am new to OLAP API (Java), I spend some months in Hyperrion Essbase JAPI, now turn to Oracle but feel quite confused about a lot of concept. Here is a task in my hand that is to present the dimension tree in XML format, just like:
<?xml version="1.0" encoding="GBK"?>
     <Member name="Market" gen="1">
          <Member name="East" gen="2">
               <Member name="New_York" gen="3" />

I didn't find ways on how to get child nodes for a given node, for example, how can I get East,West,South,North nodes (called "member" in Essbase) from "Market" node?

and there is line in code ( object name =/bi/olapService) is this line is constant or i should use or it depends on my PC)
can any one explain it and exaplain the connectionj code
thanks

hi oracle guys
thanks , but i can't do this at all.
did u mean i can patch olap engine to newer one
and keep my DBMS oracle9i release 1
but i need to solve to my proplem, and how to make
the connection not to change my oracle because
this not just joke to change my oracle release
so did any one tried to connect to olap oracle9i 9.0.1
please help ,my project depends on this project
