Database configuration files in e.Spreadsheet
e.Spreadsheet and BIRT reports has the ability to change the data source connection information at runtime using configuration files.
In e.Spreadsheet Designer, you can create a data source to provide the connection information for a database or other data source. When you run a report using Actuate iServer system, you can use a different data source connection than the connection that you provided int her eport. You can change the connection information for one report or update the connection information for every report that you run on an iServer machine. To set run-time connection information, you usea connection configuration file.
Using a connection configuration file
A connection configuration file is an XML file that you can use to set data source connection settings to use when Actuate iServer system runs a report. The settings that you include in a connection configurtaiton fiel can overrride the settings in a report. For example, you can develope a report using one data source, such as a test database. Then, you can create a connnection configuration file to run the report with a differnt data source, such as the production equivalant production database.
You can use the same connection configuration file for every spreadsheet report that you run on Actuate iServer. e.Spreadsheet Designer and BIRT use the same connecton configuration file. Each entry in the file is specifically for a particular product.
Actuate iServer expects the file to be in UTF-8 encoding, which allows a variety of special characters. You can also a file with only ASCII characters.
There is no default location for the connection configuration file. To use a connection configuration file, you create the file and then specify its name and location using the ConnConfigFile parameter in Actuate Management Console. Set the ConnConfigFile parameter to the absolute path and name of your connection configuration file. If you have a cluster of iServers, each iServer in the cluster must have access to the file. The path can be local absolute path and name of your connection configuration file must be specified for each iServer in the server configuration. If you use a single copy of the file for a cluster, put the file in a shared location and then specify the path to that shared location for all iServers in the cluster.
When you run a report, Actuate iServer uses the connConfigFile parameter to identitfy where to find a configuration file. Actuate iServer uses the connection information in the file to connect to a datasource. If no configuration file exists, or if the file does not correctly specify a data source, then Actuate iServer uses the connection information from the datasource definition in the spreadsheet report.
Creating a connection configuration file:
To create a connection configuration file, create an XML file and provide connnection values for one more data sources. Each entry in a connection configuration file must include the name of the data source and one or more of the available properties for a connection to that data source.
To override teh connection information in an e.Spreadsheet Designer data source, create a ConnectOptions element with one or more property sub-elements, using the following syntax.
data_source_name
prop_value
* connection_name is an identifier used to identify a set of connection properties for a data source. The connection name must be unique within the set of connection name identifiers for a particular product. For example you can use Production_db as a connection name for an e.Spreadsheet Designer connection and for a BIRT connection. The connection name does not need to match the name of the data source in the report.
* Data_source_name is the name of the data source that the report uses. The data source name must match the name of the data source in the report.
* Property_name is the case-insentive name of the property toset
* Prop_value is the property's value.

Chracter or list of characters to be recognize as the delimiters of the columnnames property. If this property is
not set, it uses its default value, ",;:".
Property Name: Columnnames
Delimited list of names to assign to columns. This property is ignores unless this data source is a fixed-width or delimited
text file.
Property Name: ColumnTypes
Comma-delimited list of number formatting to assing to columns. For example , G,G,N,S,T is a list of number formats for five columns. This property is ignores unless this data source is fixed-width or delimited text file. Valid characters include:

Example of a sample configuration file:
The following example shows how the settings in a connection configurationf iel can direct Actuate iServer to use production server when it runs a report. Both the development database and the production database use the Oracle thin drive. The connection configuration file change the SalesConnection data source from the develoment database, devserver, to the production database, prodserver:
SalesConnection
jdbc:oracle:thin:@prodserver:1521:salesdb
iServer Express
