How to calculate Week Start Date and Week End date using DAY_DT in Obiee 11g

In OBIEE 11g, many times we have to calculate on the fly, the various dates functions like Week_Start_date, Week_End_Date, Previous_Yr_Date etc,  just using the Date column. Few projects have Date Dimensions not properly structured to have all columns. So here we have the logical sql’s to calculate the same:
We can calculate the week start date using the below sql:
TIMESTAMPADD(SQL_TSI_DAY,- DAYOFWEEK(MIN(“Dim – Date”.” Date Column”)) + 1, MIN(“Dim – Date”.” Date Column”))
For Week End Date, use the below Sql:
TIMESTAMPADD(SQL_TSI_DAY, 7-DAYOFWEEK(MAX(“Dim – Date”.” Date Column”)), MAX(“Dim – Date”.”Date Column”))
DAYOFWEEK returns an integer in the range of 1 to 7. A value of 1 represents the Monday.

New Features in OBIEE 11.1.1.9.0 release:


 Some more new features have been introduced in latest OBIEE 11.1.1.9.0 release:-

Analysis Enhancement:

1.     You can initiate a search within the subject area displayed in the subject area pane; the option is “Subject Areas Pane”.
2.     You can save columns to Presentation Catalog and reuse the same for other analysis.You can also change the properties of the new column in the Criteria tab but be aware that conditional formatting and conditional action links for the column are not saved to the catalog. Regular action links are saved for the column as well as the format properties.The saved column can be edited from the catalog pane and catalog page. All the changes that you make in the catalog are applied to every analysis that used this column. If you modify it inside a particular analysis, these changes are valid only for the analysis that you are working on.To be able to save new measures as columns you should have the Save Column privilege.
  
 
3. In this version we find a new new type of variables: the Global Variables. Global Variables can be defined in the context of an analysis and can be used in other analysis. Useful to do some intermediate reusable calculations.
4. Radio button and check box dashboards prompts can be showed horizontally. When you create a new dashboard prompt using check box or radio button under Options, you can select between horizontal or Vertical Layout appears under Options.

Export & Print options:

1.     In this version, you will find more options in the Print and Export Options dialog. You can select if you want to include charts, images and formatting or to specify column properties like the column width and to wrap the text in columns.

2.     Export menu no longer includes the Excel 2003 and PowerPoint 2003 options
3.     It is possible to set a limit to the number of rows downloading as CSV format

New RPD checkout option:

1.     If you need to check out an entire repository rather than using projects for multiuser development, you can use the Whole Rpd Checkout option


New Option in Administration Tool:

1.     Display Translation Key in presentation tree and Edit Presentation names options are now available in Administration Tool option for this release. Translation keys have been added to all presentation objects. The translation key is automatically populated and by default it matches the presentation object’s name; however, you can modify the translation key. When you externalize display names in the Presentation layer and run the Externalize String utility, the results contain the translation key. You can right-click any Presentation layer object, such as a subject area, presentation table, or presentation column, and choose Externalize Display Names > Generate Custom Names or Externalize Descriptions > Generate Custom Descriptions to externalize strings.

Report/Dashboard Changes:

1.     Once you are in editing dashboard, you might see the Advanced Page properties option that set the scope of parameters in cases of Go URL, Prompted URL and Navigate to BI content:

 2. In Tables, Pivot and similar you can see Column properties from the edit window as well.

Usage of Key Performance Indicators In OBIEE

To assess your business performance, you must define success via Key Performance Indicators (KPIs), benchmark metrics against which current performance can be measured.
OBIEE 11g allows you to define and customize KPIs, and to then integrate them into your dashboard. In this way you can assess current performance at a glance. Your KPI Watchlist can also be used to create analyses and agents that trigger based on certain threshold conditions and actions.


To create the KPIs, take the following steps:

1.    Log in to Oracle Business Intelligence Enterprise Edition 11g, using your username and password. From the home page, select New -> KPI from the common header area. When prompted to select a subject area, for example select any Sales/Revenue related.
  
2. The KPI Entry screen will then appear. This screen enables you to define the actual value and target value measures for the KPI, as well as an optional time offset to show performance as a trend.

3. Then, you specify the dimensionality of the KPI,by for example making it analyzable by two levels in the store hierarchy, and two in the time hierarchy or
you want users to be able to switch the product category for which the KPI is displayed but you want the year, 2010, to stay constant (or “pinned”). To do this, click the Add button on the Dimensionality screen, select the “Times”.”Year”attribute, and select 2010for Value. Then click Addagain to add the “Stores”.”Product” attribute column, but leave Value as Not Pinned. Click Next to proceed to the next step in the process: defining the thresholds. 
The values used for these dimensions can either be “pinned”,so that they stay static for this KPI, or
they can be dynamic, allowing the user to change them to vary their “point of view”. As well as using
regular  “attribute” columns to define these dimensions, you can also use complete hierarchies in the
form  of hierarchical columns from the semantic model presentation layer.


4. On the Thresholds screen, you can specify values that will determine whether the performance achieved warrants an OK, Warning, or Critical indication. In this example, performance will be considered OK if it is within 90 percent of the target and critical if it falls below 70 percent.

 

5.  Click Next to proceed to the next step, where you can define related documents for the KPI. This enables users to reference other analyses, external Web pages to support the KPI. For this example, however, there are no related documents, so click Finish to move to the final steps, where you can name and save the KPI.
 You can create more KPI in similar manner.

Displaying KPIs, Using a KPI Watchlist

Now that you have defined one or more KPIs, you can give users a means of displaying these on a dashboard through a KPI watchlist. To create a KPI watchlist, take the following steps:
1.    From the Oracle Business Intelligence home page, select New-> KPI Watchlist.
2.    From the Catalog view on the left-hand side of the screen, drag and drop the  KPIs you created previously onto the watchlist on the right. The selected KPIs will then be displayed in a grid format, showing the actual and target values, along with the variance and the percentage variance.

OBIEE11g Grand Totals with Calculated formulae (divison)

Lately, we ran into a User specific scenario, where they wanted us to display Grand total row also as division of total members and participants, based on region.
We tried a lot to achieve it through aggregation rule, using server complex aggregate, but it was not giving correct result. As you can see in image below:

Scenario was to achieve Grand total for “% Finalized column” as 154.33  instead of summation (sum) 598.86. Since our report was a Union Report , so we tried new functionality of OBIEE 11g , named “Add Result Column”.
We wrote small formula in Edit column as below, where saw_1 is region, saw_2 is Total Members and saw_3 is Participants
(Sum(saw_2 by saw_1)/Sum(saw_3 by saw_1)*100.00)
This gave us the correct answer.

Connection Pools


Connection Pools – What it is and Best Practices 

The Connection pool is an object in the Physical layer that describes access to the data source. It contains information about the connection between the Oracle BI Server and that data source.

The Physical layer in the Administration Tool contains at least one connection pool for each database. When you create the Physical layer by importing a schema for a data source, the connection pool is created automatically. You can configure multiple connection pools for a database.
Connection pools allow multiple concurrent data source requests (queries) to share a single database connection, reducing the overhead of connecting to a database. For each connection pool, you must specify the maximum number of concurrent connections allowed. After this limit is reached, the connection request waits until a connection becomes available. Increasing the allowed number of concurrent connections can potentially increase the load on the underlying database accessed by the connection pool.

Improperly defined connection pool would affect the OBIEE performance and user experience. Here are some tips to consider while defining connection pool.
  • Change the default maximum connections. The default is 10. Based on your system usage change the value that is more realistic to your system usage
  • Create a separate connection pool for execution of session variables
  • Create a separate connection pool for the execution of aggregate persistence wizard. Remember that you need to give the schema user owner credentials for this connection pool as the wizard creates and drops tables
  • If need be create a separate connection pool for VVIPs. You can control who gets to use the connection pool based on the connection pool permissions.
