Oracle Express Dimension attributes

Hi,
I would like to create a multi-dimensional database with Oracle Express. I don't how to define dimensions with attributes.
Is anybody can help me?
Thank you.

why is it slow even though i acces the site from my own pc where is oracle express is install..Probably because you have too much going on the machine.
Oracle database works best if it can get 250-400 M Ram to itself. It gets real bad when there is a lot of paging or swapping - which is an OS problem, not really Oracle's problem.

Dimension Attribute Write Back

Is it possible to write-back and update a dimension attribute. If so, could someone please post an example doing this.
Thanks!

I assume that your question is about Oracle-OLAP dimension attribute (and not Essbase).
You will have to come up with a custom front-end (web or windows) where you will enter (or change) the attribute value. Then behind the scenes, you will call DBMS_CUBE.BUILD procedure to update the attribute value for that dimension member.
Here is an example:
Dimension = 'ACC', Hierarchy = 'ACCHIER', Dimension Member = 'CM1' and we want to update an attribute value called "LONG_DESCRIPTION" for this member 'CM1'.
begin
dbms_cube.build(q'! "ACC" USING (
SET "ACC"."LONG_DESCRIPTION"["ACC" = 'CM1'] = CAST('Custom Member 1' AS VARCHAR2),
MERGE INTO HIERARCHIES ("ACC"."ACCHIER") VALUES ('CM1', 'ALL_ACC', NULL),
COMPILE)!');
end;

ORACLE OLAP: trying to read french dimension attributes fails

We have set up the CHANNEL dimension of the GLOBAL AW to have a french translation for the attributes CHANNEL_SHORT_DESCRIPTION and CHANNEL_LONG_DESCRIPTION. Using the AW Manager we had verified that the french values are output correctly. Also when using the OLAP Worksheet we got the correct output. Unfortunately issuing the same sequence of commands via ODP.NET does not output the dimension attribute in the appropriate language. Does anybody know about this problem or have the same experience?
Here is the command stack of the Olap Worksheet
->RPR DOWN CHANNEL CHANNEL_SHORT_DESCRIPTION SKIP
--------------ALL_LANGUAGES--------------
----------------AMERICAN-----------------
CHANNEL_SHORT_DESCRI
CHANNEL PTION
1 All Channels
4 Internet
2 Direct Sales
3 Catalog
->LOCK_LANGUAGE_DIMS=no
->LMT ALL_LANGUAGES TO 'FRENCH'
->RPR DOWN CHANNEL CHANNEL_SHORT_DESCRIPTION SKIP
--------------ALL_LANGUAGES--------------
-----------------FRENCH------------------
CHANNEL_SHORT_DESCRI
CHANNEL PTION
1 All Channels
4 Internet
2 Ventes Directes
3 Catalogue

Just to update this thread: while preparing a little test program, which should make this problem reproducable, I found an ALLSTAT command in our lengthy command stack. This caused the ALL_LANGUAGES_DIM to loose its limit on the selected language. Our parser in turn didn't have any trouble with this, but output the first language, which was the default. The problem was on our side and is solved now.

Converting from Oracle Express Objects to Standard Form

Hi,
I have create an EIF file from our Oracle Express database, then I have created an Analytic Workspace and imported the EIF file. After this I identify the Time dimensions. But when I want to identify the hierarchie dimension of each time dimension, it brings an Error: "ORA-34492: Analytic Workspace Object Jan96 does not exists", but when I look in the OX there exists the object. Where is the problem?
Thanks Diana

Did you run the conversion program listed in the documentation:
If your Express database contains Oracle Express Objects metadata (that is, it was created by Oracle Express Administrator), then you can use a conversion program named CREATE_DB_STDFORM. Without Oracle Express Objects metadata, CREATE_DB_STDFORM cannot generate sufficient standard form metadata for the OLAP tools to work.
This should generate the required metadata but you will not to create some additional attributes to correctly manage time as the conversion utility does not do everything for you:
If you want to perform time-based analysis on your data, you must identify all time dimensions and populate end date and time span attributes before using CREATE_DB_STDFORM. A sample program is provided in this appendix:
Create date and time span attributes for each dimension.
DEFINE TIME_TIME_SPAN VARIABLE INTEGER <timedim hierdim>
PROPERTY 'USERDATA' FALSE
DEFINE TIME_END_DATE VARIABLE DATE <timedim hierdim>
PROPERTY 'USERDATA' FALSE
Populate the end date and time span attributes, as described in "Populating Time Attributes".
Set properties on the Time dimension:
CONSIDER timedim
PROPERTY 'END_DATE' attribute_name
PROPERTY 'TIME_SPAN' attribute_name
The END_DATE and TIME_SPAN values (attribute_name) identify the names of the variables that you just created.
Run the conversion tool with a command like this:
CALL CREATE_DB_STDFORM('aw')
Refer to the syntax description in "CREATE_DB_STDFORM Syntax". After the conversion tool completes successfully, save the changes:
UPDATE
COMMIT
Hope this helps

Oracle Express Performance

Hi,
We are using Oracle Express 6.3.2 & Oracle 8.1.5 for a decision
support system that we are building.
We are using a server with 2GB RAM, Dual CPU( 550MHz) along with
more than 100 GB HDD.The OS being used is Windows NT enterprise
edition server 4.0.On which both Oracle Relational database and
Express express server resides.
The building of multi-dimensional database(MDDB) doesn't take
time, we are using around 9 dimensions with total data in MDDB
being in the range of 5- 10 Lakhs records.The building time is
about 3 minutes.
However, the running of an application(XPJ) based on the MDDB
takes lot of time. The report takes about 2 Minutes to appear
and situtation is even worse in what-if analysis kind of
reports!.The MDDB is being accessed from Windows NT Client
workstation 4.0 with 128 MB RAM.
We have read Oracle Express Performance Tuning and Database
Design Guide which is available from both Oracle Technology
Network (technet.oracle.com) and Metalink, however it doesn't
seem to be of much help.The sparsity etc. have been taken care
of by us.
CAN ANYBODY PROVIDE ASSISTANCE ON THIS ISSUE OR IS IT NORMAL
THING TO EXPECT FROM ORACLE EXPRESS????...., .Request someone to
respond to this issue, as it very urgent & bothersome to us.
Thanks

Dear Friend,
I am trying to configure reports for express data and in this regard I have done the following :
1.Machine A having reports 9i Developer suite Release 2 and Pluggable Express Connection Editor installed on Windows 2000 professional.
2.Machine B having which Express Server 6.3.4 installed on Windows 2000 professional.
3.In Machine A created user OESDBA with Administrator privilige.
In the reports I am able to connect to the Express Server and attach the database and choose the measure.Once all the other steps are done I am able to print the data on the reports.
But if I use a parameter form in which I give the HOST,USER and PASSWORD then substitute the same in the express_server parameter value in the AFTER PARAMETER FORM trigger block then the report gives an error saying that
Express query contains incorrect,missing or damaged information.
How to solve this error ?
Can you please help.

Oracle Reports 6.x and Oracle Express Server

What are the benefits of using Oracle Reports in conjunction with Oracle Express Server? We are currently using OFA for planning and forecasting, and are evaluating Oracle Reports as a tool to produce and publish key financial reports for a large user community. Is there any benefit in using Oracle Reports rather than just creating and publishing the reports directly within OFA?
Thanks,
Bill

Bill,
we tried to use Reports 6i with Express server. There were many troubles.
1. It is very hard task to establish connection Reports/Express
2. It is not possible to enter parameters for the reports
3.There are limitation on the number of dimensions in the report

Oracle Express perfomance problem

Hi, I am facing performance issues with following application in Oracle Express using OFA as front end. There are 9 dimensions in cube and one measure. DB size 18-20 GB. geography and time dimension is dense, all other are composite. Leaf level data for one month and one geography is 50k rows only. It is taking more than 1 hour to run following command.
allstat
lmt geography to 'G036'
lmt time to 'DEC06'
value=na
upd
I have to na the data before uploading new data. could someone pls suggest some better way to na the data, which should be faster?
thanks very much.

The fastest method would be to rename your geography and time dimension values
to a temp value (to be removed on your next eif export/import)
And then add them back and load ..
ie
mnt time rename 'DEC06' 'XDEC06'
mnt geography rename 'G036' 'XG036'
update
mnt time add 'DEC06'
mnt geography add 'G036'
" NO Need TO NA Anything .. just load your data
You could try deleting the members instead of the rename .. but this caused
me some problems in the past .. so i found the rename to work better.

OLAP Dimension Attributes in a BI Beans Crosstab

Hello,
How can I show my custom OLAP dimension attributes in the BI Beans Crosstab?
Can I compare this attributes with the measures?
I have a cube with three dimensions and I have defined some limit amounts which are valid only for one of the dimensions. Additionally they are defined only for aggregated levels in this dimension.
I was wondering whether I could define these limit amounts as dimension attributes and use them to compare with the measures.
Is there any other possibility?
Maybe I can create my custom column in the Crosstab?
Thanks in advance,
Michal

I would recommend using the built-in security feature of the analytic workspace. There is a command called PERMIT that can be applied to both dimensions and cubes and controls user access to dimension members.
There is a document on the OLAP home page that explains how to secure and AW using the permit command

Problem with Oracle Express Administrator

Hi everybody,
I want to ask about Oracle Express Administrator,
Please tell me why variable I define in Relational Access always be function in my express? the data always 0.00 too ? I use table Oracle in this
And why always make three database ? after the batch manager ?
Please I'm new with Express Administrator.
Best Regards,
Djohan Wahyudi

This is the way every Express object that is modelled gets implemented at the physical level. Each object has a physical storage object, which is a variable that is usually dimensioned by a composite to manage storage sparsity. This physical object is difficult for users to understand as the dimensionality is not based on the presentation format the user will want. Hence, a logical object (a formula) is used to breakout the variable into the base dimensions making it easier for users to interact with from the perspective of creating queries. There is more information in the user guides on this subject.
I would recommend upgrading to 10g Release 2 rather than using Express. The latest release of the database contained an OLAP multi-dimensional engine within the core database. There is no separate engine like there is with Express and the administration and management tools are much easier. Please refer to the OLAP wbsite on OTN for more information:

'dimension attribute was not found' error while refresing the cube in Excel

Dear All,
Thanks for all your support and help.
I need an urgent support from you as I am stuck up here from nearly past 2-3 days and not getting a clue on it.
I have re-named a dimension attribute 'XX' to 'xx' (Caps to small)in my cube and cleared all dependencies (In Attribute relationship tab as well).
But while refreshing the data in excel client (of course after processing the full cube) I get an error
'Query (1, 1911) the [Dimension Name].[Hierarchy Name].[Level Name].[XX] dimension attribute was not found' error.
Here I am trying to re-fresh an existing report without any changes with the new data.
Does not it re-fresh automatically if we clear the dependencies or there something that I am missing here (Like order of the dependencies).
Cube processed completely after modifications and able to create new reports without any issues for same data. What else could be the reason?
Can some one help me here?
Thanks in Advance and Regards,

Thnaks alot Vikram,
In se11 ,when i was trying to activate the /BIC/FZBKUPC , it is showing the warnings like
Key field KEY_ZBKUPCP has num. type INT4: Buffering not possible, Transport restricted.What it means.
In PErformance Window it is showing like:
A numeric type was used for a key field. A table of this sort cannot be buffered.When buffering, the table records for numeric values cannot be stored in plain text.
Procedure
You can enter "no buffering" as an attribute of the technical settings and then repeat the activation process. The table is not buffered.
If you want to buffer the table, you must replace the type in the key field by a character type, i.e. that you must modify the table.
Please adivice with your valueable suggestyions.
Thanks Vikram.

How can I login to Oracle Express Ed 11g Rel 2 on windows XP 32bit?

I installed Oracle Express Ed 11g Release 2 32bit on windows XP 32bit and I can not login ito it. Installation asked for a password to be created at installation which I used to login with.
The login window is started from a shortcut that installation created on my desktop. I tried to download and install three times. I went thru a SW removable before another download. The login responds with "Invalid Login Credentials"
I have admin rights to my PC. What could be the issue?
Please help.
Thanks.

What could be the issue? Could be many different causes. Mistyping the password is one, or the database could be offline but in most cases that will give a different error message. Open a command box, Start/Run/cmd and try:
$ sqlplus /nolog
connect system
... Password ... <the one used with the installer> ... Connected.
select name from v$database;
login window is started from a shortcut If you're talking about the Apex page, the one that opens a web browser to http://<hostname>:8080/apex and that one needs Apex credentials, not database user credentials. Apex users can be mapped to database users but that is something done via the apex administrator.
Two database accounts "out of the box" are SYS and SYSTEM users, those are special- SYS owns the catalog, SYSTEM is a user with dba role privileges, almost as powerful within the database as the SYS user.

How to use unixODBC with Oracle Express on Ubuntu 8.10?

I downloaded Oracle Express a couple of days ago, so I am totally new to Oracle.
I tried connecting via unixODBC, using dsn=oracledsn, user=dba, password=abcd and received error info:
1: st=01000, nerr=0, msg=
[unixODBC][Driver Manager]Can't open lib '/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/lib/libsqora.so.10.1' : file not found
but the shared 'so' library actually does exist at the path above. I also set
ODBCINI=/etc/odbc.ini;export ODBCINI and immediately checked it was in the environment.
The .ini files are:
/etc/odbcinst.ini
[OracleExpressdrv]
Driver = /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/lib/libsqora.so.10.1
Description = Oracle 10g express driver
/etc/odbc.ini
[ODBC Data Sources]
oracledsn = Oracle Express DSN
[oracledsn]
Driver = OracleExpressdrv
Note: The dsn and the driver names are enclosed within square brackets but came out as web links above in the preview.
After many hours of googling I have not been able to find how to connect via ODBC to a local (on my PC) Oracle Express.
Advice would be most welcome.

hello
I have the same problem. My system is Fedora 11
I set the odbcinst.ini and odbc.ini files as you mentioned. I also set the LD_LIBRARY_PATH :
$ echo $LD_LIBRARY_PATH
/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/lib/
when I try to connect using isql, I get that error:

I couldn't figure out what I am missing.
May someone help please?

JSP 1.2: jsp expression in attribute value doesn't parse.

Hi, I'm trying to use a jsp:expression in an html attribute value in JSP 1.2 but jasper doesn't seem to be able to parse it correctly. I'm using the XML syntax in my jsp, the relevant snippets are as follows:
<jsp:scriptlet>
String versionedPath = "/mysite/2.1/images";
</jsp:scriptlet>
<img src="%= versionedPath %/foo.jpg" />
The JSP documentation claims that this will work but I'm beginning to think this syntax won't work when using JSP's XML syntax. I already know that the following won't work:
<img src="<jsp:expression> versionedPath </jsp:expression>/foo.jpg" />
as it did in JSP 1.1 because it's not well-formed xml.
Is it even possible to use jsp expressions in attribute values when using JSP 1.2's XML syntax? If so, please enlighten me, and if not, well, that seems pretty broken to me.
TIA...
--Stuart

you should use this:
<img src=<%= versionedPath %>/foo.jpg >

Oracle Express Server v.6.3.1.0 installation problem

I downloaded oes6301nt.exe - Oracle Express Server - NT (118MB) from the Oracle web site, unzipped it and start using Universal Installer to install it for stage/product.jar. I specified Oracle Home as OraExpress81 and path as F:\Oracle Express\olap and chose a typical installation.
At about 98% completion, I got an error: Invalid Search Spec or no DLLs found F:\Oracle*.dll on a error meassge box with an OK button. I clicked the OK button and the installation went to 100% and gave me a message "The installatio of Oracle Express Server was successful. I then re-booted the machine.
But when I tried to run the Express Instance Manager, it wouldn't start. It just blinked for 5 sec then quited.
I checked the programs, the installed programs are:
Program -> OracleExpress81 ->Application Development ->INTYPE File Assistant
NetWork Administration -> Net8 Assistant
Net8 Configuration Assistant
Net8 Easy Config
Express Instance Manger
Express Server 6.3.0 -> Express Instance Manager
Express Language reference
Could you please tell me what could probably be wrong with the installation. Thanks for your help in advance.
