The server name must match what is defined in the Tnsnames. Credentials are required to run queries, to preview the report locally, and to preview the report from the report server. After you publish your report, you may need to change the credentials for the data source so that when the report runs on the report server, the permissions to retrieve the data are valid.
To create a dataset, you can either select a stored procedure from a drop-down list or create an SQL query. To build a query, you must use the text-based query designer. You can specify stored procedures that return only one result set. Using cursor-based queries aren't supported. If the query includes query variables, corresponding report parameters are automatically generated.
Named parameters are supported by this extension. For Oracle version 9 or later, multivalue parameters are supported. Report parameters are created with default property values that you might need to modify. For example, each report parameter is data type Text. After the report parameters are created, you might have to change default values. A custom data processing extension or. NET Framework data provider must be compiled natively for a specific platform. This column answers the question: "Can this data processing extension or data provider be installed on this type of platform?
Many standard. NET Framework data providers are available from third parties. For more information, search the third-party Web sites or forums. To install and register a custom data processing extension or standard. NET Framework data provider, you will need to refer to the data provider reference documentation.
For more information, see Register a Standard. This data processing extension is natively compiled for and runs on x86 and xbased platforms. If you use the query designer in graphical mode, the query is analyzed and possibly rewritten. Use the text-based query designer when you want to control the exact Transact-SQL syntax that is used for a query.
In Report Builder, the query designer associated with this data extension is the Relational Query Designer. A text-based query designer is also available for writing queries. This data source has been deprecated. Results are returned as a flattened rowset. For Azure Analysis Services and Power BI Premium dataset data sources, you must have multi-factor authentication MFA disabled for the credentials being used to connect to the data source.
If you need multi-factor authentication enabled for your environment, review Azure Active Directory Conditional Access as an option to disable multi-factor authentication for the credentials used in the data source. When connecting to an Analysis Services data source, the Microsoft SQL Server Analysis Services data processing extension supports multivalue parameters and maps cell and member properties to extended properties supported by Reporting Services.
The OLE DB data processing extension requires the choice of an additional data provider layer based on the version of the data source you want to use in your report.
If you do not select a specific data provider, a default is provided. Choose a specific data provider through the Connection Properties dialog box, accessed through the Edit button on the Data Source or Shared Data Source dialog boxes. This data processing extension is natively compiled for and runs on x86 and x64 platforms.
Unnamed parameters that are position-dependent are supported. Named parameters are not supported by this extension. To use named parameters, use the Oracle data processing extension. For more information about configuring Oracle as a data source, see How to use Reporting Services to configure and to access an Oracle data source.
Although a data provider may support previewing a report on your report authoring client, not all OLE DB data providers are designed to support reports published on a report server. When you select data source type ODBC , you are selecting a Reporting Services data processing extension that extends the. Use this extension to connect to and retrieve data from any data source that has an ODBC provider.
Although a data provider may support previewing a report on your report authoring client, not all ODBC data providers are designed to support reports published on a report server. To retrieve data from a data source that supports a standard ODBC. NET Framework data provider, use the ODBC data source type and select the default data provider, or select from the installed data providers in the Connection String dialog box.
When you select data source type Oracle , you are selecting a Reporting Services data processing extension that uses Oracle's Data Provider directly and no longer uses the Microsoft System. OracleClient provider as it has been deprecated. To retrieve report data from an Oracle database, your administrator must install Oracle client software and the version must be 11g or later.
It must be installed on the report authoring client to preview reports and on the report server to view published reports. Named parameters are supported by this extension. For Oracle version 11g or later, multivalue parameters are supported.
You can retrieve data from stored procedures with multiple input parameters, but the stored procedure must return only one output cursor. For more information about the associated query designer, see Graphical Query Designer User Interface. The Reports Server accesses the cache and sends the report to output according to the runtime parameters specified in either the URL, the command line, or the keyword section in the cgicmd.
Another way to create a report is through event-driven publishing. With event-driven publishing, the client is the database rather than the end user. With Oracle Reports 12 c Release With the broadcast mechanism, Reports Server discovery can occur within a subnet or across subnets:. On your desktop, right-click My Network Places , and choose Properties.
The subnet mask field will automatically populate. Do not use the local host IP that is, For example, enter: Solution for UNIX platform: Configure the discovery mechanism to disable the built-in broadcast mechanism and enable the COS naming service instead, by replacing the multicast element with the namingService element in the network configuration file rwnetwork.
Solution for both Windows and UNIX platform : Configure the discovery mechanism to disable the built-in broadcast mechanism and enable the COS naming service instead, by replacing the multicast element with the namingService element in the network configuration file rwnetwork. Within a subnet, the client broadcasts a packet with the name of the Reports Server to which it wants to connect. A Reports Server with that name will respond if it exists in the network.
The client then connects to the Reports Server to run the report request. The Oracle Reports client for example, rwclient , rwservlet , or rwrqm broadcasts a packet containing the name of the server to which it wants to connect.
Oracle Reports provides the Oracle Reports Bridge mechanism for connecting two or more non-secured subnets. To configure the naming service, refer to Section 7.
Read this section to learn more about Oracle Reports Services: Section 2. When used in a Web environment, the Oracle Reports Services architecture consists of four tiers: Note: The term tier refers to the logical location of the components that comprise the Oracle Reports Services architecture.
Each of the tiers, though, can reside on the same machine or on different machines. For calling jobs from an HA Reports server, you must use a load balancer.
For example, if the requester specified five minutes as the TOLERANCE , the Reports Server would check its cache for the last duplicate report output that had been generated within the last five minutes. For more information, see Section A. Note: When you configure the Reports Server in rwserver. If the Reports Server is under this maximum, then it can send the job to an idle engine or start a new engine to handle the request.
Otherwise, the request must wait until one of the current Oracle Reports Engines completes its current job. Note: It is recommended that you use the built-in broadcast mechanism for dynamic discovery of Reports Servers. Use the Common Object Service COS naming service for Reports Server discovery only when the built-in broadcast mechanism is not suitable for your environment, as in the following scenarios: You plan to install Oracle Reports on a machine that is connected to a network using VPN.
You want to avoid broadcast traffic on your network. Note: Oracle Reports 12 c Release Using rwdiag, you can replace the functionality of osfind available in the prior VisiBroker implementation, providing information about which ORB applications are running and options for logging ORB-related network traffic.
Thus, following are two scenarios in which the broadcast mechanism may not work, including the solutions for each scenario: If the host machine is not in a network that is, it is a standalone machine.
