can you please guide me below mentioned topics? Please share doc if possible
Building Plans and transforms
1. describing and building palns in BAM
2.Working with data flows
3.Describing and identifying the types of transforms in BAM
4.Including Transforms in Plan

Hi
There are technotes on how to Setup ODI-BAM configuration under BAM 11g --> Technotes section.
In addition, there is an ODI tutorial in the samples and tutorials section for BAM 11g.
If you need more support, please reach out to support to contact the Product Management team for BAM.
It sounds like you are using EL in 10g . We can support any questions on the migration but you will need to raise this through support.

Integration HP Planning and Budgeting to Oracle eBS.

hey guys,
i am very new to Hyperion and i want to know how to integrate Hyperion Planning and Budgeting to Oracle eBS.
thanks and regards,
Rahul.

Hello,
Unfortunately there is no prebuilt package that makes "Planning the source for OracleEBS". Right now the ERPi software you are looking at will only control budgetting information. You can review the current compliance of the software by doing a review of the documentation under the chapter "Data Write-back Rules".
If you are looking to source pure data from Planning into OracleEBS then a custom solution will need to be developed and maintained outside of the Hyperion software .... or built to plug into the Hyperion Software (like ODI).
Thank you,

Error when transporting Oracle datasource and transformation.

I am doing transports in BI 7.0 from DEV to PRD. While moving transformation for Oracle Data Source to PRD, I am facing the method of execution error in transport. Please note for the same target we are using two transformations from different Oracle data sources. One is getting transported to PRD. while the other one is failing with error message source system does not exist.
Please help me to solve this issue. Points will be assigned.

Hi Davis,
Before transporting transformation make sure either of source or target should availble in target system.
suppose you have a transformation between Data source and Data Target, first transport Data source, then transport Transformation along with data target.
Before tansporting Transformation either source or target should be avaialble in QA system..then only transportation will happen smoothly..
Hope this helps.

Preview freeze and not working fine on PDF view (building plans)

Imac 27" 5k i7 32GB Osx 10.10.1
When opening a PDF in preview (mostly building plans) some lines are not viewable. When enlarging the pdf and every time i'm scrolling preview freeze for a 30".
(in quick view (mail) the hole PDF is perfect viewable but not scaleable)
Also secured PDF could not be enlarged.
This al worked perfect on Mavericks on my other Imac 27" i7 16GB (mid 2011) 10.9 before upgrading to 10.10 (now it have de same problems as my brand new 5k)
I hope apple coms whit an solution quickly.

Firewall issues were preventing this problem.

I have a class where I need to use SmartDraw but it is not compatible with Mac probook what are some other software programs I can use to make floorplans and building plans?

I am suppose to download SmartDraw to my computer for a class but it is not compatible with Probook is there another program that does the same as SmartDraw? I am planning a building addition and need it for the floor plans. Any help would be greatly appreciated.

There are lots of choices. Just go to the App Store and type in Cad Drawing in the search field. Also Sketchup from Google is a cloud based solution hat works pretty well.

Hi Ajay,
I presume you are talking about this section http://download.oracle.com/docs/cd/E10773_01/doc/oim.1014/b25355/deployinstall.htm#BABHIJGJ . This section does specify the sizing for some deployment scenarios. It is not brief. We cannot propose the hardware configuration for any customer just referencing this.
Please let me know your thoughts.

Questions on Enterprise Planning and Budgeting

Hi,
First of all: this may be a very wrong place for posting these questions. However, I could not find a forum that seemed closer to the matter so I try it anyway.
With EPB close to hitting the streets, some questions starting popping up - especially now that Oracle has recommended one of my customers - who is just starting out with Business Intelligence and are not E-Business Suite users - to embark on the EPB course.
It is stated by Oracle that EPB - although it is an integrated component of the Oracle EBusiness Suite â can be used as stand-alone product. You can load data into interface tables. Questions:
Does EPB work on its own Data Warehouse and if so, is this DWH also available to other OLAP tools for Analysis? Or should organizations doing Analysis and Reporting apart from EPB have a separate DWH for those OLAP queries?
Does Oracle recommend loading data directly from operational sources into the FEM Interface Tables or does Oracle think it best for non-EBusiness Suite customers to set up a Data Warehouse independently of EPB and in a later stage implement processes to extract data from that DWH into the FEM Interface. Are the FEM Interfaces tables at the operational (fact) level or do they already have some sort of consolidation in them?
Can Oracle somehow convince us that while EPB does not provide hooks for customization it will offer reports desired by non-EBusiness Suite customers with potentially very varied businesses? How much of EPB benefits are you missing out on if you do not have the E-Business Suite? What is EPB then giving you that with OWB and BI Beans/Discoverer you can not easily build yourself?
The specific case of my customer: they have clear requirements for Management Information. Most of these are about analyzing histrical data (the classic slicing and dicing); forecasting and budgeting would be a nice to have in the longer run. They currently do not have a proper Data Warehouse. They have a consolidation point for some operational data. No dimensions have been defined, no data cleansing is performed and some data is not available at all. I am wondering whether EPB would be the proper tool for them to start with. Given their requirements as well as their lack of current experience with BI as well as the relative uncertain situation with regard to the data sources, I would feel more comfortable with a more down-to-earth approach: start designing a DWH and the processes to populate it as well as developing the most urgently needed reports. In that case, EPB would be brought in at a later stage â when the organization as well as the data management is ready for more advanced stuff.
Is there anyone, especially from Oracle, who would care to comment? Also on my feeling that Oracleâs recommendation to use EPB is perhaps somewhat influenced by Oracleâs desire to build up references and experience with this brand new tool â that, as I understand it, is not even generally available â only a âcontroller releaseâ is available right now.
Thanks for anyone for your insights.
best regards,
Lucas

Please note these are not official Oracle or my employers answers, just my interpretation. Hope this might help though.
"Does EPB work on its own Data Warehouse and if so, is this DWH also available to other OLAP tools for Analysis? Or should organizations doing Analysis and Reporting apart from EPB have a separate DWH for those OLAP queries?"
EPB has it's own EPF schema, which it shares with Oracle's other CPM applications, but it's not a traditional warehouse schema arranged as a star schema, you're not supposed to load data directly into it, and it's really designed for storing data that needs to be loaded into AWs for analysis. You'll therefore still need to build your own warehouse schema, and then load data (through the interface tables) into the EPF schema for use with EPB.
"Does Oracle recommend loading data directly from operational sources into the FEM Interface Tables or does Oracle think it best for non-EBusiness Suite customers to set up a Data Warehouse independently of EPB and in a later stage implement processes to extract data from that DWH into the FEM Interface. Are the FEM Interfaces tables at the operational (fact) level or do they already have some sort of consolidation in them?"
It depends. Data can be loaded directly into the EPF (new name for FEM) schema, but you'll probably want to cleanse and transform it first, most probably in a data warehouse. The data that goes into the EPF schema is at transaction level, and EPB will perform any aggregations as it loads data into it's AW. Of course data in the form of balances - that goes into the EPF balances table - will be to an extent already summarised (or at least snapshotted) but the twenty user data tables are just regular fact tables, with the granularity set to whatever you require.
"Can Oracle somehow convince us that while EPB does not provide hooks for customization it will offer reports desired by non-EBusiness Suite customers with potentially very varied businesses? How much of EPB benefits are you missing out on if you do not have the E-Business Suite? What is EPB then giving you that with OWB and BI Beans/Discoverer you can not easily build yourself?"
Too early to see really, especially as no-one apart from Oracle has done an EPB implementation yet. With regard to the question about what EPB gives you that OWB and BI Beans don't already give you, I think the relevant bit is "you cannot easily build yourself". EPB is an application, not a toolset, and it'll appeal to those people that want to buy a supported planning and budgeting application from Oracle, that integrates with e-Business Suite and doesn't require them to build everything from the ground upwards. With OFA and OSA you could have course build a similar application yourself, using Visual Basic or Express Objects and Express Server, but for most people buying it from Oracle was a more sensible solution.
"The specific case of my customer: they have clear requirements for Management Information. Most of these are about analyzing historical data (the classic slicing and dicing); forecasting and budgeting would be a nice to have in the longer run. They currently do not have a proper Data Warehouse. They have a consolidation point for some operational data.

In that case, EPB would be brought in at a later stage â when the organization as well as the data management is ready for more advanced stuff."
Yes, I'd agree with this approach. EPB isn't the place to start integrating and consolidating data, and the EPF schema isn't where you'd want to store your complete data warehouse. You could of course, using the twenty data tables and the user defined dimension tables, but you'd pretty much be limited to querying via EPB (the schema isn't really suitable for querying directly using tools such as Discoverer) and the AW that EPB creates wouldn't be suitable/supported/documented for use by regular OLAP API tools such as Drake or the BI Beans. If it was down to me, I'd build the warehouse as normal, using OWB or any other ETL tool, create my dimensional model as normal, then take selected data out and put it in the EPF schema, and then carry out my planning & budgeting using EPB. I'd then still run Discoverer / Discoverer "Drake", or BI Beans or any other ad-hoc query tool against my warehouse schema for the warehouse "power users", and use EPB as the application for my finance and planning department,

Enterprise Planning and Budgeting

Dear All
Does the Module enterprise planning and budgeting provides controlling functionality similar to encumbrance accounting in GL, or any other control functionality on transactions like Requisition/PO/Invoice Item Wise...?

Oracle Hyperion Planning, including PBCS, does not include built in functionality for pre-expenditures (a.k.a. encumbrances) or most other accounting controls you would find in PeopleSoft / Fusion Financials. However, you can build this type of functionality into your Planning application.
For example, you could use the Version dimension in Planning (or create a seperate dimension for this purpose) to contain children members which would hold multiple entry types:
Version
     + Approved
     + Encumbrances
     + Adjustments
Version would equal Approved + Encumbrances + Adjustments. Then you could create a Business Rule to do the following: 1) Approved = Approved + Encumbrances 2) Clear Encumbrances. You could build the security in Planning to control who can input into "Approved" and who can run the Business Rule. You could even use the Hyperion Planning workflow capabilities to incorporate work-flow controls into this process.
Hyperion Planning, and PBCS, provides the flexibility to build most financial processes and controls, but it is certainly not out-of-the-box functionality.
Hope this helps.

OWB 9i -Mapping and Transformation

From the Module Editor I created the sample_mapping using the MAPPINGS/Create Mapping. All I see is the single option to create the mapping and there is no option to attach a module to the mapping name. Any help will be appreciated. Thanks

It was step 2, 3 and 4 under section "Create Mappings and Transformations" found in document "Creating a Data Warehouse Using Oracle Warehouse Builder " on here OTN. Has the process changed in OWB9i?.
Thanks

Workforce Planning in Planning and Budgeting Cloud Servie

Hi Experts,
Does Oracle Planning and Budgeting Cloud Service (PBCS) have Pre-build modules Workforce Planning, Capital Asset Planning and Project Finance Planning.
According to my understanding PBCS doesn't have any pre-build modules. I am not sure whether recently it has been added or not, so I wanted to double check.
Thanks in Advance.
Regards
SKH

PBCS still does not offer other planning modules like Workforce plnning/Capex etc.
you can see more info at https://docs.oracle.com/cloud/latest/pbcs_common/CSPGS/apes02.html

Problems with explain plan and statement

Hi community,
I have migrated a j2ee application from DB2 to Oracle.
First some facts of our application and database instance:
We are using oracle version 10.2.0.3 and driver version 10.2.0.3. It runs with charset Unicode 3.0 UTF-8.
Our application is using Tomcat as web container and jboss as application server. We are only using prepared statements. So if I talk about statements I always mean prepared statements. Also our application is setting the defaultNChar property to true because every char and varchar field has been created as an nchar and nvarchar.
We have some jsp sites that contains lists with search forms. Everytime I enter a value to the form that returns a filled resultset, the lists are performing great. But everytime I enter a value that returns an empty resultset, the lists are 100 times slower. The jsp sites are running in the tomcat environment and submitting their statements directly to the database. The connections are pooled by dbcp. So what can cause this behaviour??
To anaylze this problem I started logging all statements and filled-in search field values and combinations that are executed by the lists described above. I also developed a standalone helper tool that reads the logged statements, executes them to the database and generates an explain plan for every statement. But now there appears a strange situation. Every statement, that performs really fast within our application, is now executed by the helper tool extremely slow. So I edited some jsp pages within our application to force an explain plan from there (tomcat env). So when I'm executing the same statement I'm getting with the exactly same code two completely different explain plans.
First the statement itself:
select LINVIN.BBASE , INVINNUM , INVINNUMALT , LINVIN.LSUPPLIERNUM , LSUPPLIERNUMEXT , LINVIN.COMPANYCODE , ACCOUNT , INVINTXT , INVINSTS , INVINTYP , INVINDAT , RECEIPTDAT , POSTED , POSTINGDATE , CHECKCOSTCENTER , WORKFLOWIDEXT , INVINREFERENCE , RESPONSIBLEPERS , INVINSUM_V , INVINSUMGROSS_V , VOUCHERNUM , HASPOSITIONS , PROCESSINSTANCEID , FCURISO_V , LSUPPLIER.AADDRLINE1 from LINVIN, LSUPPLIER where LINVIN.BBASE = LSUPPLIER.BBASE and LINVIN.LSUPPLIERNUM = LSUPPLIER.LSUPPLIERNUM and LINVIN.BBASE = ? order by LINVIN.BBASE, INVINDAT DESC
Now the explain plan from our application:
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 101 | 28583 | 55 (0)| 00:00:01 |
| 1 | NESTED LOOPS | | 101 | 28583 | 55 (0)| 00:00:01 |
| 2 | TABLE ACCESS BY INDEX ROWID| LINVIN | 93709 | 12M| 25 (0)| 00:00:01 |
|* 3 | INDEX RANGE SCAN | LINV_INVDAT | 101 | | 1 (0)| 00:00:01 |
| 4 | TABLE ACCESS BY INDEX ROWID| LSUPPLIER | 1 | 148 | 1 (0)| 00:00:01 |
|* 5 | INDEX UNIQUE SCAN | PK_177597 | 1 | | 1 (0)| 00:00:01 |
Predicate Information (identified by operation id):

filter("LINVIN"."BBASE"=:1)

Now the one from the standalone tool:

| 3 | TABLE ACCESS BY INDEX ROWID| LSUPPLIER | 16540 | 2390K| | 332 (0)| 00:00:04 |

| 5 | TABLE ACCESS BY INDEX ROWID| LINVIN | 93709 | 12M| | 6073 (1)| 00:01:13 |
|* 6 | INDEX RANGE SCAN | LINVOICE_BMDT_FK | 93709 | | | 84 (2)| 00:00:02 |
Predicate Information (identified by operation id):
2 - access("LINVIN"."BBASE"="LSUPPLIER"."BBASE" AND "LINVIN"."LSUPPLIERNUM"="LSUPPLIER"."LSUPPLIERNUM")
4 - access("LSUPPLIER"."BBASE"=:1)
6 - access("LINVIN"."BBASE"=:1)
The size of the tables are: LINVIN - 383.692 Rows, LSUPPLIER - 115.782 Rows
As you can see the one executed from our application is much faster than the one from the helper tool. So why picks oracle a completely different explain plan for the same statement? An why is a hash join much slower than a nested loop? Because If I'm right a nested loop should only be used when the tables are pretty small..
I also tried to play with some parameters:
I set optimizer_index_caching to 100 and optimizer_index_cost_adj to 30. I also changed optimizer_mode to FIRST_ROWS_100.
I would really appreciated, if somebody can help me with this issue, because I'm really getting more and more distressed...
Thanks in advance,
Tobias

Hi again,
Here ist the answer:
The problem, because I got two different explain plans, was that the external tool uses the NLS sesssion parameters coming from the OS which are in my case "de/DE".
Within our application these parameters are changed to "en/US"!! So if I'm calling in my external tool the java function Locale.setDefault(new Locale("en","US")) before connecting to the database the explain plans are finally equal.That might explain why you got two different execution plan, because one plan was obviously able to avoid a SORT ORDER BY operation, whereas the second plan required to run SORT ORDER BY operation, obviously because of the different NLS_SORT settings. An index by default uses the NLS_SORT = 'binary' order whereas ORDER BY obeys the NLS_SORT setting, which probably was set to 'GERMAN' in your "external tool" case. You can check the "NLS_SESSION_PARAMETERS" view to check your current NLS_SORT setting.
For more information regarding this issue, see my blog note I've written about this some time ago:
http://oracle-randolf.blogspot.com/2008/09/getting-first-rows-of-large-sorted.html
Now let me make a guess why you observe the behaviour that it takes so long if your result set is empty:
The plan avoiding the SORT ORDER BY is able to return the first rows of the result set very quickly, but could take quite a while until all rows are processed, since it requires potentially a lot of iterations of the loop until everything has been processed. Your front end probably by default only display the first n rows of the result set and therefore works fine with this execution plan.
Now if the result set is empty, depending on your data, indexes and search criteria, Oracle has to work through all the data using the inefficient NESTED LOOP approach only to find out that no data has been found, and since your application attempts to fetch the first n records, but no records will be found, it has to wait until all data has been processed.
You can try to reproduce this by deliberately fetching all records of a query that returns data and that uses the NESTED LOOP approach... It probably takes as long as in the case when no records are found.
Note that you seem to use bind variables and 10g, therefore you might be interested that due to the "bind variable peeking" functionality you might potentially end up with "unstable" plans depending on the values "peeked" when the statement is parsed.
For more information, see this comprehensive description of the issue:
http://www.pythian.com/blogs/867/stabilize-oracle-10gs-bind-peeking-behaviour-by-cutting-histograms
Note that this changes in 11g with the introduction of the "Adaptive Cursor Sharing".
