New Release 1z0-591 Oracle Certification Questions

There are static and dynamic repository variables.

Note:

Variables in the Oracle BI Server can be either repository or session variables, and are defined using the Variable Manager within the Oracle BI Administrator (Manage > Variables).

This brings up the Variable Manager, that divides variables out into repository and session variables, with a further subdivision into static and dynamic repository ones and system and non-system session ones. You can also define variables at the Presentation Server level, these are scoped to individual dashboards and are used amongst other things for setting dashboard prompt values and integrating the dashboard with BI Publisher parameters. Here’s a screenshot of a typical Variable Manager screen.

Oracle Essbase developers creating planning and budgeting applications have been keenly aware of the advantages and disadvantages of the two different storage types available to them:

* Block storage option (BSO) databases support a wide range of calculations, including forecasts, allocations, and aggregations through procedural calculation scripts. The results of these calculations can be written back to the database, but applications that use BSO storage are limited to about 10 dimensions and member counts in the low hundreds of thousands.

* Aggregate storage option (ASO) databases can support about 20 dimensions and member counts in the millions. ASO databases use multidimensional functions rather than procedural scripts to perform calculations, but the results of queries cannot be stored back in the database, making ASO unsuitable for most financial management applications.

In online mode, you connect to a catalog on a running web server. In this mode your permissions are applied, you can select a locale, and you can see the effects of any localization on the catalog. You can see only those objects for which you have the appropriate permissions. Both Presentation Services and the web server must be running for you to open catalogs in online mode.

Use online mode when you want to make minor incremental changes or additions to the catalog, such as changes to permissions, updates to a single object, or migration of new objects to a production environment.

Note:

* You can open a catalog in one of two modes — online or offline. Both modes can operate against an actual production catalog, with no need for any downtime.

* Repository changes can be done in either online

or offline mode. Online mode is when BI Server

is actively reading the repository file (when a

user is logged in). Offline is when BI Server is

idle. Best practice is to develop in Offline mode.

Minor changes can be made when in online

mode.
