OLAP objects based on Views

Hi
I am creating OLAP objects (Dimension and Fact) based on views. Log generated by validation API showing that all objects (dimension, cube and catalog) in catalog are valid. But when I am using Jdev to create presentation based on that it is giving me following error. I am using JDev 9.0.4.0 Build (1419).
oracle.dss.dataSource.common.QueryRuntimeException: BIB-9509 Oracle OLAP did not create cursor.
oracle.express.ExpressServerExceptionError class: OLAPI
Server error descriptions:
DPR: Unable to create server cursor, Generic at TxsOqDefinitionManagerSince9202::crtCurMgrs2
OES: ORA-00979: not a GROUP BY expression
, Generic at TxsRdbSelectStatement:execute()
Can you provide some input on this if something special is required to create catalog based on views? If you can give me sample script or any online resource that I can try in my env it would be helpful.
Thanks in advance.
regards
Prakash

I would recommend posting this on the OLAP forum.

Can Data Links be established between Data sets based on View Objects?

Hi all,
In the BI Publisher Documentation it's given that Datasets based on view object queries do not support Data Links / Group Links. We found out that only way to establish relationship between view object Datasets is to create a view link and then upload it to create a Dataset.
1. Is there any other way to establish relationship between view objects Datasets in DataModel editor itself just as in the case of data sets based on (SQL queries e.t.c.)?
2. If so can View object Datasets be linked to Datasets based on other Datasources?
3. Will the Datalinks for View object Datasets be supported in any of the upcoming releases. Is there any ER logged for this case?
Any insight on the above issues will be really helpful.
Thanks

Enhance the data source with date and time and populate these fields in the user exit using the function module IB_CONVERT_FROM_TIMESTAMP .
OR
You can create Z function module IB_CONVERT_FROM_TIMESTAMP in BW side and write a routine in update rules/transfer rules to populate date and time.
hope this helps ...

Problem with 2 View Objects based on One Entity -Probably a Bug in ADF BC

Hi
I am using JDeveloper 10.1.3(SU5) and adf faces and ADF BC and to explain my problem I use HR schema.
First, I created 2 view objects based on countries table named as TestView1 and TestView2. I set TestView1 query where clause to region_id=1 and TestView2 query where clause to region_id!=1 in the view object editor and then I created 2 separated form on these 2 view objects by dragging and dropping from data control palette.
Now when I insert a record in the form based on TestView1 with region_id set to 1 and commit the record and go to the next form I can see the record in the second form which is completely wrong since it is against the where clause statement of the second form.
I am really confused and the situation is very wired and it seems to me something like bug in adf bc.Am I right.Is there any work around or solution for solving this problem.
Any help would be highly appreciated.
Best Regards,
Navid

Dear Frank,
Thank you very much for your quick response.
Reading your helpful comments now I have some questions:
1- I have commited the record in the database so shouldn't the query of view objects be re-queried?
2- We try to use ClearVOCaches (entity_name,false) in afterCommit of the base entity object but unfortunately it does not work correctly. after that,We got root app module and used findViewObject method to find all the view of that entity (we have found them by using name not automaticlly) and called executeQuery of all views. From my point of view it has 2 big disadvantages. First suppose that this entity is an important entity and 4 or 5 viow objects are based on it. Now, For inserting one record we should re-execute 4 or 5 view which I think makes some performance issues. Besides, If during the development one programmer add a new view object based on this entity and don't add the executeQuery in the afterCommit for this view, again we have the same problem. Isn't there at least a way that automatically refresh all related view objects however the performance issue still exists.
3- You mentioned that this issue is handled in the developer guide. Could you kindly give me a refrence which developer guide you mean and which section I should read to overcome this problem.(I have ADF Developer's Guide for Forms/4GL Developer's Guide , however I search for clearVOCaches and surprisingly nothing was found!!!)
4- Could you please give me some hints that from your point of view what is the best method to solve this problem with minimum performance effect.
Any comment would be of some great help.
Thanks in advance,

Which is better creating view accessor based on view object or view instanc

When creating view accessors whether in the entity object or in the view object, we have two options:
1- create the view accessor based on a view object.
2- create the view accessor based on a view instance.
what are the differences between these two options?
what are the cases where I should only use option 1 or option 2?
which one is better?

Hello Timo,
I will try to explain my question better.
when we create view accessor, after click on create new view accessor icon, the create view accessor window is opened, at the header of this window there is a statement says:
Select a view object or shared view instance and shuttle it to the selected list to create a view accessor.
and here is my concern, which one to use
1- select a view object from one of the available view object and shuttle it to the selected list.
2- select a view instance from the application module and shuttle it to selected area.
If you have FOD sample (and I am sure you have it :) ), I see that oracle team has used both of them in different places, for examples
1- in oracle.fodemo.storefront.entities.PersonEO all view accessors are created from view instance in SharedLookupService application module.
<ViewAccessor
    Name="PersonTypesVA"
    ViewObjectName="oracle.fodemo.storefront.lookups.LookupsBaseVO"
    AMUsageName="SharedLookupService"
    ViewInstanceName="PersonTypes"/>is it because they are used to create LOV?
2- in oracle.fodemo.storefront.entities.OrderEO the view accessor is created from a view object, not from instance inside application module.
    <ViewAccessor
    Name="OrdersVO"
    ViewObjectName="oracle.fodemo.storefront.store.queries.OrdersVO"/>I couldn't find the usage of this accessor?
Hope it is clear now.

Separate App Module, View Object based on Select not EO: Best practice?

Hi,
I have a list of base tables(parameters) that are used everywhere in my application for selection components (List, Combo, Radio).
I'm considering creating a separate app module with a view object based on query for each table.
I have created a BaseTableAM application module for managing those tables, Entity objects and View Objects in update mode.
Those tables are rarely changed.
Example of table:
ItemType
item_type_id = primary key
name = description
In the BasetableAM:
ItemTypeEO entity object
ItemTypeVO updateable view object based on related entity object.
Now in my project I will create combo boxes for selection of the item_type_id.
Separate application module:
SelectionViewAM composed of View Objects based on Select statements and not on Entity Objects.
Example of view object ItemTypeViewVO:
SELECT ItemType.ITEM_TYPE_ID,
ItemType.NAME
FROM ITEM_TYPE ItemType
All view objects in this application module will be read-only and for selection only.
By basing all those View Objects on select statements not based on Entity Objects I suppose there will be no locking and "value changed" management => less overhead.
Is this a good practice?
Being read-only I could have based those View Object on Entity Object with flag updateable set to no, what would you recommend?
By creating a separate Application Module for those selection view objects, I know that update will not be possible.
Thank you for your advice.
Frederic

See this article for View Object tuning tips:
http://www.oracle.com/technology/products/jdev/tips/muench/voperftips/index.html
Are you planning to use this AM as a nested AM inside other application modules?
If you don't the "selection AM" will have its own, separate database connection/transaction.
If you do, it will share connection, transaction with its containing "root" AM.
It may not be relevant to your application, but just realize (which is explained in the article I point to above) that view objects that are not related to entity objects do not "see" pending changes in the current transaction. That feature depends on the VO/EO cooperation. It's fine to build VO's without an EO -- in fact we've made it easier to do this in 10.1.2 in the Design Time wizards -- but you just want to make sure you realize what features it's giving up. If you don't need those EO-related features, then by all means create an Expert Mode VO that's not related to EO's.

Create LOV in form that is not based on view

Hello
I have this problem: I'm making a form that is not based on view object. From the Data Controls I can drag a view as a combo box, but I cannot drag a view as a ListOfValues ...
So I must create a non-SQL-based View and create attributes of my form and attach the LOV to one of the attributes ?
Is there another solution ?
Thanks
agruev

Yes, input list of values must be model driven.
What we do is :
Create Dummy view as:
Select 1 as id,
null as code
from dual;
and we bind code with list of values view object.

Out of memory Error while querying SQL Script based Calculation View

Hi All,
I wanted to test the performance of Graphical and SQL Script based Calculation views.
Created Graphical (CA_GRPH) and SQL Script (CA_SQL) Calculation views.
Analytic View (AN_GRPH) for both Calculation views are the same which is Graphical based (90 Attributes and 5 Measures)
In Analytic View data foundation I have a Fact table which has 1.5 Billion records and 9 Dimension Tables –collectively 500 million records (7 Attribute Views). 9 Referential joins with cardinality N:1 and 1 Referential join with cardinality N:N.
I wanted to keep (CA_GRPH) and (CA_SQL) as a base Calculation views and leverage those to create various calculation views (Will be creating different Calc views for respective Business segments)
In order to test this I have created below calc views on top of base calc views.
Graphical Based: Created (CA_GRAPH_XYZ) by having CA_GRPH in projection with 30 Calculated Columns. – This retrieves data in 13 secs
SQL Script Based: Created (CA_GRPH_ABC) by having CA_SQL in projection view with 30 calculated columns – This errors out after 1.50 mins.
Could not execute 'SELECT "COLUMN_A","COLUMN _B"," COLUMN _C"," COLUMN _D", SUM("COLUMN _REVENUE") AS ...' in 1:50.480 minutes .

Hi Raj,
Thanks for your time, please find edited snap hot of Analytic View (AN_GRPH) below,

END
/********* End Procedure Script ************/
Later i have built one more Calculation view(CA_GRPH_ABC) using (CA_SQL)in projection. i have 30 calculated measures in this final calc view. this final calc view is throwing above mentioned error.
Not sure if i can use SQL script based calc view in graphical based calc views?

Is the fact that it doesn't exist in the database a problem ?
Is the fact that it is active is good enough ?
By the way thanks for your speedy reply !

Role-Based CLI Views with AAA method

Hi,
I'm configuring Role-Based CLI Views on a router for limiting access to users.
My criteria:
- There should be a local user account on the router that has the view 'service' attached to it
- If the router is online and can reach the radius server, people in the correct group are assigned the view 'service'
My configuration:
aaa new-model
enable secret 1234

The ERROR
Now I want to go configure the cli view 'service'...
# enable view
Password: 1234
*Jun 1 08:00:02.991: AAA/AUTHEN/VIEW (0000000D): Pick method list 'mgmt'
*Jun 1 08:00:02.991: RADIUS/ENCODE(0000000D): ask "Password: "
*Jun 1 08:00:02.991: RADIUS/ENCODE(0000000D): send packet; GET_PASSWORD
*Jun 1 08:00:21.011: RADIUS: Received from id 1645/13 10.1.1.1:1645, Access-Reject, len 20
The Questions
Why does the 'enable view' try to pick a method list when you have to supply the enable secret to access the root view?
Can you change this behaviour to always use the enable secret?
The TEMP Solution
If you're logged on to the router via telnet or SSH, the solution or workaround to this issue is:
aaa authentication login VIEW_CONFG local
line vty 0 4
login authentication VIEW_CONFG
Do your configuration of the view and re-configure the line to use the correct (wanted) method of authentication.
Thanks so much for the suggestions

hi,
You have the following configured:
aaa authentication login mgmt group my_radius local
aaa authorization exec mgmt group my_radius local
line con 0
authorization exec mgmt
logging synchronous
login authentication mgmt
line vty 0 4
authorization exec mgmt
logging synchronous
login authentication mgmt
transport input ssh
Hence every time you try to login to the console or try the ssh the authentication will head to the radius server because of the following command "login authentication mgmt".
You cannot make it locally. Whatever defined on the method list mgmt first will be taking the precedence.
enable seceret will be locally defined. but you have the following configured:
aaa authorization exec mgmt group my_radius local
line con 0
authorization exec mgmt
line vty 0 4
authorization exec mgmt
Hence exec mode will also be done via radius server.
when you configure:
aaa authentication login VIEW_CONFG local
line vty 0 4
login authentication VIEW_CONFG
You are making the authentication local, hence it is working the way you want.
In short, whatever authentication is defined 1st on the method list will take precendence. the fallback will be checked only if the 1st aaa server is not reachable.
Hope this helps.

Anisha
